Chapter 31 — Patient MC-09

At 7:32 in the morning, Lu Chen discovered another sign.

He stared at it.

Lu Xiaoxiao stared back.

Neither moved.

The sign had been taped directly beneath the consultation fee notice.

PATIENTS ARE PEOPLE

Lu Chen read it twice.

Then:

“That one can stay.”

Xiaoxiao blinked.

“Really?”

“Yes.”

“No fight?”

“No.”

She looked suspicious.

“You sick?”

“No.”

She climbed onto a chair and touched his forehead.

“Normal.”

“Thank you.”

She sat back down.

Madam Zhou entered carrying breakfast.

“What did she do now?”

Lu Chen pointed toward the sign.

Madam Zhou read it.

Then nodded approvingly.

“Good.”

Xiaoxiao smiled proudly.

“Daddy agrees.”

“That must be serious.”

Lu Chen looked toward both of them.

“Why is everyone surprised when I agree with something reasonable?”

Xiaoxiao answered immediately.

“Because rare.”

Madam Zhou turned away to hide a laugh.

The clinic door opened.

Jian Wei walked in.

Xiaoxiao pointed toward the sign.

“Uncle Jian.”

He read it.

Then looked at Lu Chen.

“What happened?”

“Nothing.”

“You suddenly discovered ethics?”

Lu Chen stared.

Jian sat down quickly.

“Good sign.”

Xiaoxiao nodded.

“Also your fee six times.”

His face fell.

“Still?”

“Permanent.”

Lu Chen almost approved.

Qin Ruoxi arrived at 7:48.

Deng Hu followed.

Dr. Zhao had already called twice.

Su Qingyue sent one message:

I’ll meet you at the hospital. Hanmei legal records are with me.

Good.

No unnecessary convoy.

No one was bringing Qin Zhenguo.

Also good.

The old man had argued.

Naturally.

Dr. Zhao had won.

Barely.

Lu Chen handed Xiaoxiao to Madam Zhou for kindergarten.

She looked toward the adults.

“You finding Patient Nine?”

“Yes.”

“Is patient sick?”

“We don’t know.”

“Then check first.”

Lu Chen paused.

Simple.

Correct.

“That is the plan.”

She nodded.

Then held out her hand.

“What?”

“Lunch money.”

“You have lunch.”

“Emergency.”

“For what?”

“Candy.”

“No.”

She sighed dramatically.

“Medical emergency.”

“No.”

Madam Zhou dragged her away before negotiations escalated.

Qin Medical Center looked completely ordinary from the outside.

That had become suspicious by itself.

Patients moved through the lobby.

Nurses carried charts.

A man argued with billing.

A child cried because someone had mentioned an injection.

Normal hospital.

Underneath it—

old sealed corridors.

Compromised medical systems.

A hidden vault.

An abandoned Hanmei server room.

A Wake Plate.

And apparently Patient MC-09.

Dr. Zhao met them outside the executive elevator.

He looked at Jian Wei.

“No weapons.”

Jian glanced at the sword strapped beneath his coat.

“This is medical equipment.”

“No.”

“It has been used medically.”

“That makes it worse.”

Lu Chen stepped into the elevator.

“Leave it with Deng Hu.”

Jian stared.

“You too?”

“Yes.”

“This hospital is hostile.”

Zhao pressed B2.

“It is accredited.”

“Same thing.”

Ruoxi looked away.

Su Qingyue entered just before the doors closed.

Dark suit.

Tablet.

No strawberry scarf today.

Xiaoxiao would complain.

She looked at Lu Chen.

“Temperature?”

He frowned.

“Mine?”

“No.”

“Yours?”

“Yes.”

“36.5.”

He stared.

“You checked?”

“Your daughter sent me a message.”

Silence.

Ruoxi slowly looked toward Su.

“She has your number?”

“Yes.”

Lu Chen closed his eyes.

“How?”

Su’s expression remained calm.

“I gave it to her.”

“Why?”

“Emergency strawberry-milk logistics.”

Jian made a strange choking sound.

Lu Chen decided the hospital investigation was safer.

They did not go to B3 first.

They went to medical records.

Dr. Zhao insisted.

Correctly.

“MC-09 is a patient designation,” he said as they entered the restricted records office. “We start with the chart.”

Su shook her head.

“Hanmei classified it as a research case.”

“That is Hanmei’s problem.”

Zhao tapped the hospital counter.

“If the person received care here, there is a clinical record.”

Lu Chen nodded.

Su looked between them.

“You two agreeing remains unsettling.”

“We are not friends,” Zhao said.

“No,” Lu Chen added.

Ruoxi smiled.

“Of course.”

A senior records administrator had already prepared access under Qin family authorization and current medical-review authority.

No broad search.

No mass export.

Specific case.

Good.

The administrator typed.

“MC-09 does not exist as a patient number.”

Su frowned.

“It exists in Hanmei.”

“Yes, President Su. But not in our hospital-number format.”

“What cross-reference?”

The administrator searched.

One result.

Restricted.

She looked toward Ruoxi.

“Executive privacy hold.”

“Opened by?”

The woman hesitated.

“Former Vice President Luo Jian.”

Of course.

Ruoxi authorized access.

The record opened.

Everyone became still.

Clinical patient name:

SHEN YULAN

Lu Chen’s expression changed.

Jian looked toward him.

“You know her.”

“Yes.”

Ruoxi did too.

“Hidden vault.”

“Yes.”

Su looked between them.

“Who is she?”

Lu Chen answered:

“A patient I treated.”

He did not say more until he read.

Good habit.

The hospital record continued.

Internal Meridian Research Cross-Reference: MC-09

There.

Same case.

No new person.

Someone they already knew.

Dr. Zhao folded his arms.

“She is still admitted.”

Lu Chen looked up.

“Where?”

“Recovery floor. Private room.”

“Status?”

“Stable.”

“Since when?”

“Since you saved her.”

Good.

No casual repeat life count.

She had already crossed that threshold once.

Treating her again would not automatically become another acknowledged life.

Ruoxi looked toward the chart.

“Why was she in the hidden vault?”

The records administrator shook her head.

“Not in standard chart.”

Of course.

“Who moved her there?”

Another restricted note.

Luo Jian.

Seven months ago.

Then a later transfer order.

Four months ago.

Then acute event.

Recent.

The period when Lu Chen had found her.

He read everything in sequence.

First admission:

Recurrent syncope. Episodic peripheral cold sensation. Transient numbness.

Nothing extraordinary yet.

Cardiac workup largely normal.

Neurology inconclusive.

Then one peculiar incident.

During a routine blood draw, the tube had been placed beside an old meridian-conduction calibration plate awaiting disposal.

The blood-tube temperature dropped by 2.8 degrees Celsius.

Localized.

Temporary.

No matching drop in Shen Yulan’s body temperature.

Interesting.

Su leaned closer.

“That is why Hanmei classified her under Cold Response Phenotypes.”

“Yes.”

“C-9.”

“Yes.”

But it was not Su Qingyue’s condition.

Different.

Very different.

Lu Chen continued.

Subsequent controlled observation—

before anyone had obtained formal research consent—

reported another temperature drop when the sample was exposed to an archived meridian-imprint substrate.

That was a problem.

Not merely medically.

Ethically.

“Who ordered the second exposure?” Lu Chen asked.

The administrator checked.

“Research request originated from Hanmei.”

“Approving physician?”

Silence.

Then:

Shen Yao.

Dead.

Su’s expression chilled.

“He had already been dead by then.”

“Yes.”

The administrator looked uncomfortable.

“System accepted the credential.”

Lu Chen had heard that story too many times.

Then Luo Jian entered the chart.

His handwritten note had been scanned.

STOP RESEARCH PROCESSING.

All capital letters.

Below:

Patient has consented to clinical testing only. No valid research consent exists.

Then:

No further exposure of biological material to Meridian Conduction substrates.

And:

MC-09 IS A PATIENT CROSS-REFERENCE, NOT OWNERSHIP OF THE SAMPLE.

Finally:

Patient not property.

There it was.

Full context.

Ruoxi read slowly.

“He protected her.”

“In this instance,” Lu Chen said.

Important.

One good act did not erase waking Ruoxi without permission.

One violation did not erase another act of medical ethics.

People remained inconveniently complicated.

Su continued down the page.

“Hanmei appealed.”

“Yes.”

“Who denied?”

The administrator looked.

“Luo Jian.”

“Second appeal?”

“Approved.”

Everyone became still.

“By?” Su asked.

The woman swallowed.

“Shen Yao.”

Dead again.

Ruoxi’s expression hardened.

“So the dead credential overruled the living hospital vice president.”

“Yes.”

“Did the transfer happen?”

“No.”

“Why?”

The next note answered.

Luo Jian had physically placed a hold on the specimen storage unit.

Manual.

Not digital.

Three signatures required for release.

His.

Patient’s.

Independent physician.

Only his appeared.

The patient had never signed.

Good.

Dr. Zhao looked toward Lu Chen.

“Before we investigate the sample, we speak to Shen Yulan.”

“Yes.”

Su closed the chart.

“Agreed.”

Ruoxi looked at her.

“You’re surprisingly patient today.”

“This concerns a patient whose material was almost transferred into a company I now control.”

Su’s voice cooled.

“I would like to know what my company inherited before someone tells me I own it.”

Good.

They went upstairs.

Shen Yulan was awake.

She sat by the window reading a paperback novel.

No monitors beyond basic observation.

No oxygen.

No IV.

She looked healthier than when Lu Chen had last seen her.

Color returned.

Pulse stronger.

Life Meridian stable.

Good.

She looked up.

Then froze.

“Doctor Lu.”

Lu Chen nodded.

“How do you feel?”

She stared at the crowd behind him.

“Concerned.”

Reasonable.

“There are too many important-looking people.”

Su Qingyue glanced toward Ruoxi.

Ruoxi glanced toward Jian.

Jian looked at himself.

“I look ordinary.”

“No,” Shen Yulan said.

“You look like trouble.”

Lu Chen almost smiled.

“Accurate.”

Jian looked betrayed.

Lu Chen approached alone first.

“May I examine you?”

“Yes.”

Pulse.

Normal.

Temperature.

Normal.

Neurological check.

Normal.

Life Meridian.

No obvious foreign graft.

No Northern House winter lattice.

No Quiet Heart mark.

No Borrowed Pulse architecture.

Good.

He withdrew.

“No acute problem.”

Shen Yulan relaxed.

“Then why are you here?”

“MC-09.”

Her expression changed immediately.

There.

Recognition.

She closed the book.

“Who told you?”

“Hospital records.”

She looked toward Su Qingyue.

“Hanmei?”

Su stepped forward but remained several feet away.

“I own Qinghe Pharmaceutical Group. Qinghe acquired Hanmei.”

Shen Yulan’s expression hardened.

“Then I don’t consent to anything.”

Su answered immediately.

“Understood.”

No argument.

Shen Yulan seemed surprised.

Su continued:

“I am here because someone used a dead Hanmei executive’s credentials to request your sample.”

A pause.

“I want to know whether my company was used against you.”

Shen Yulan looked at Lu Chen.

He nodded once.

Factually accurate.

She thought.

Then:

“You can ask.”

Good.

Her choice.

Ruoxi and Deng Hu stayed near the wall.

Jian remained outside after Lu Chen told him there were already too many people.

He complained for seven seconds.

Then left.

Progress.

Dr. Zhao sat beside the window.

Medical staff.

Appropriate.

Lu Chen asked:

“When did you first hear MC-09?”

“Seven months ago.”

“Who said it?”

“A research nurse.”

“Name?”

Shen Yulan shook her head.

“She introduced herself. I forgot.”

“Do not guess.”

“Okay.”

“What were you admitted for?”

“Fainting.”

“How often?”

“Three times in two months.”

“Trigger?”

“Twice after standing.”

“One?”

She frowned.

“After donating blood at a community drive.”

Interesting.

The narrative has been taken without permission. Report any sightings.

“Any cold symptoms before hospital?”

“Hands sometimes.”

“Whole body?”

“No.”

“Temperature drop?”

“Not that I knew.”

“Family history of Northern House, Ye family, Yunzhou maternal line?”

She looked confused.

“No.”

Good.

“Any relatives with strange cold episodes?”

“No.”

“Blood disorders?”

“No.”

“Cultivation?”

She laughed.

“No.”

“Spiritual training?”

“No.”

Good.

Separate case.

Shen Yulan continued.

“The first few tests were normal.”

“Then?”

“They drew blood.”

“Routine?”

“That’s what I thought.”

“What happened?”

“A nurse came back twenty minutes later.”

“She looked frightened.”

“Why?”

“My sample was cold.”

“Did she say how cold?”

“No.”

“Then?”

“A research team came.”

“Hospital?”

“Two wore Qin Medical Center badges. One had Hanmei.”

Su’s expression tightened.

“Did they explain the research?”

“They said my blood had shown an unusual thermal reaction and asked if I would consent to additional analysis.”

“Did you?”

“No.”

“Why?”

“They couldn’t explain what they wanted to expose it to.”

Excellent instinct.

“They said ‘calibration substrate.’”

Exactly chart language.

“I asked what that meant.”

“What did they say?”

“That it was proprietary.”

Shen Yulan’s eyes sharpened.

“So I said no.”

Good.

“What happened next?”

“The next morning they drew routine blood again.”

Her expression changed.

“I found out later they tested that one anyway.”

Su’s jaw tightened.

“Without consent.”

“Yes.”

“Who told you?”

“Luo Jian.”

There.

“What did he say?” Lu Chen asked.

Shen Yulan looked toward the ceiling, remembering.

“He came alone.”

“First time you met him?”

“Yes.”

“He closed the door.”

“I thought I was in trouble.”

“Then?”

“He asked if I had signed research consent.”

“I said no.”

“He asked if anyone had told me my clinical blood could be reused for a research test.”

“I said no.”

Shen Yulan paused.

“He got very quiet.”

Ruoxi knew that kind of quiet.

So did Lu Chen.

“What next?”

“He apologized.”

That surprised Su.

Shen Yulan continued.

“Not for himself.”

“For the hospital.”

“He said something like…”

She frowned.

Then gave the approximate wording honestly.

“‘Someone used a medical order as research permission. Those are not the same thing.’”

Good.

Then:

“He asked if I wanted all research use stopped.”

“I said yes.”

“And?”

“He stopped it.”

At least tried.

Su asked carefully:

“Did he mention Hanmei?”

Shen Yulan nodded.

“He said the request came through Hanmei.”

“Shen Yao?”

She frowned.

“I remember that name.”

“Why?”

“Because Luo Jian got angry.”

“What did he say?”

Shen Yulan thought.

Then:

“Dead signatures do not create consent.”

Silence.

Su wrote it down.

Lu Chen looked toward her.

“You’re recording?”

“Yes.”

“Good.”

She almost looked surprised by the praise.

Shen Yulan continued.

“He told the nurse to flag any order under Shen Yao.”

“Then what?”

“I thought it was over.”

“It wasn’t.”

“No.”

Her expression darkened.

Three days later, someone tried to move her.

Not discharge.

Transfer.

“To where?” Ruoxi asked.

“I was told another facility.”

“Name?”

“I never saw paperwork.”

“Who came?”

“Two transport staff.”

“Hospital employees?”

“I assumed.”

Deng Hu quietly wrote details.

Shen Yulan continued.

“I asked why I was being transferred.”

“They said specialized testing.”

“I refused.”

“What happened?”

“They left.”

“Then Luo Jian came again.”

“How soon?”

“Maybe twenty minutes.”

“Angry?”

“Yes.”

“Scared?”

She considered.

“Yes.”

That mattered.

“What did he do?”

“He moved me himself.”

“To the hidden vault?” Lu Chen asked.

Her eyes shifted.

“You know about that.”

“I treated you there.”

She nodded.

“I don’t remember all of it.”

Reasonable.

She had been very ill.

“He said the room was not ideal, but it was off the normal transfer map.”

That explained why he used it.

Not necessarily originally built for her.

“He told me I would stay there until he knew who had issued the order.”

Ruoxi’s face hardened.

“Did you agree?”

“Yes.”

Good.

Voluntary.

“At first.”

Lu Chen caught that.

“What changed?”

Shen Yulan looked down.

“After a few days, I wanted out.”

“Why?”

“No windows.”

“Anything else?”

“People kept checking me.”

“Who?”

“Mostly normal nurses.”

“Mostly?”

“There was one man.”

“Name?”

“No badge.”

“Appearance?”

She described him.

Middle-aged.

Average height.

Mask.

Gloves.

Nothing useful.

“Cultivation?”

“I wouldn’t know.”

“What did he do?”

“Checked my pulse.”

Lu Chen’s eyes sharpened.

“How?”

“Three fingers.”

Not standard.

Could be cultivator.

Could be traditional physician.

“Anything else?”

“He asked if I dreamed.”

Everyone in the room became still.

Shen Yulan noticed.

“What?”

“What did you answer?” Lu Chen asked.

“I said no.”

“Did you?”

“Yes.”

Good.

No procedural dreams.

Different case.

“What did he ask next?”

“If my left hand ever went numb.”

Ruoxi’s face changed.

Shen Yulan looked at her.

“Why?”

Ruoxi did not answer immediately.

Lu Chen did.

“Another patient has that symptom.”

True.

“Did yours?”

“No.”

“So what happened?”

“The man left.”

“Then?”

Shen Yulan swallowed.

“Two nights later, I got sick.”

There.

The acute event Lu Chen treated.

“Symptoms?” Dr. Zhao asked.

Finally entering more directly.

“Cold.”

“Whole body?”

“Yes.”

“Fever?”

“No.”

“Shivering?”

“Yes.”

“Chest?”

“Pressure.”

“Conscious?”

“Mostly.”

“Any medication before onset?”

“I had an IV.”

“What?”

“Saline, I think.”

“New bag?”

“Yes.”

“Who changed it?”

“I don’t know.”

Dr. Zhao looked toward Lu Chen.

The original event might have been induced.

They would review chart.

Shen Yulan continued.

“My hand started burning.”

“Which?”

“Right.”

Not Ruoxi.

Good.

“Then I couldn’t breathe.”

“That is when I found you,” Lu Chen said.

She nodded.

“After that, it gets blurry.”

Lu Chen remembered.

He had saved her.

Acknowledged life #9.

No need to recount the entire scene.

But now they finally understood why she had been hidden below Qin Medical Center.

Not because Luo Jian wanted to experiment on her.

At least initially—

he had been protecting her from an unauthorized transfer.

Then someone reached her anyway.

Ruoxi’s face was unreadable.

“This makes him look better.”

Shen Yulan looked confused.

“Who?”

“Luo Jian.”

Lu Chen answered before the conclusion hardened.

“In this case.”

Ruoxi nodded.

“In this case.”

Good.

He had still awakened Ruoxi without consent.

Complexity did not erase accountability.

Su asked:

“Did Luo Jian ever explain why your blood became cold?”

“No.”

“Did he think you had Northern House lineage?”

Shen Yulan frowned.

“He asked where my mother was born.”

“Where?”

“Jiangzhou.”

“Grandmother?”

“Also Jiangzhou.”

“Any Yunzhou ancestry?”

“Not that I know.”

Lu Chen looked toward Su.

No obvious maternal Northern House connection.

Good.

Su opened the Hanmei research file.

“There is a note attached to C-9.”

She read:

Possible Northern House lineage markers — sample unavailable.

Shen Yulan’s expression sharpened.

“They wrote that about me?”

“Yes.”

“It’s wrong.”

“Possibly.”

She looked toward Lu Chen.

He nodded.

“Your Life Meridian does not resemble Su Qingyue’s maternal pattern.”

Shen Yulan looked between them.

“Her what?”

“Different case.”

“Good.”

She seemed relieved.

So was Lu Chen.

They did not need every cold symptom to come from the same ancient bloodline.

Dr. Zhao requested Shen Yulan’s original lab storage logs.

The records administrator sent them.

There.

The crucial detail.

First cold event:

Blood tube had been placed beside a disposal tray containing an old meridian-imprint calibration plate.

Second event:

The sample cooled only after exposure to an archived substrate.

When no substrate was nearby—

temperature remained normal.

Lu Chen read the pattern twice.

“Your blood is not generating cold.”

Shen Yulan blinked.

“Then what happened?”

“It reacted to something.”

Su leaned closer.

“Meridian residue.”

“Likely.”

“Like recognition.”

“Maybe.”

Ruoxi looked at him.

“Possibly?”

“Either.”

She almost smiled.

Lu Chen continued:

“The important point is that Shen Yulan’s condition is not the same as yours.”

Su’s Cold Nails suppressed an inherited blood resonance.

Shen Yulan’s blood seemed to react when exposed to external archived meridian information.

Different direction.

Su transmitted.

Shen responded.

At least from current evidence.

Interesting.

The records administrator sent one more scan.

Luo Jian’s handwritten classification correction.

Lu Chen read aloud:

MC-09 IS NOT NORTHERN HOUSE.

Strong.

Then:

Cold response appears secondary to contact with foreign meridian residue. Do not merge classifications for statistical convenience.

Su’s expression darkened.

“They merged it anyway.”

The next Hanmei report grouped C-1 through C-9 under Cold Response Phenotypes.

Yes.

Someone wanted one category.

Even when the mechanisms differed.

Why?

Research convenience?

Or because they were searching for a common principle beneath different resonance illnesses?

The next line from Luo Jian:

A cold thermometer does not prove winter.

Lu Chen almost smiled.

He liked that sentence.

Su noticed.

“You approve.”

“Yes.”

“Of Luo Jian.”

“Of one sentence.”

“Important distinction.”

“Very.”

Shen Yulan looked toward all of them.

“So why did they want my blood?”

No one should hide that from her.

Lu Chen answered.

“They may have believed your sample could detect or react to preserved meridian signatures.”

She stared.

“What does that mean?”

“If biological material changes when it comes near someone else’s archived spiritual pattern, it could potentially be used as an indicator.”

“For what?”

“Identity residue.”

“Cultivation?”

“Possibly.”

She frowned.

“Like a test?”

“Yes.”

“For whether someone had touched something?”

“Maybe.”

“Whether a sample belonged to someone?”

“Possibly.”

Shen Yulan looked disturbed.

“So they wanted to use my blood like equipment.”

Silence.

Exactly.

Su’s expression became hard.

“That may be why Luo Jian wrote ‘Patient not property.’”

Shen Yulan looked at her.

Then nodded slowly.

Deng Hu finally asked:

“Did Luo Jian give you anything?”

Shen Yulan thought.

“A card.”

Everyone looked at her.

“Where?”

“My bag.”

“Still here?”

“My sister took my personal things home.”

“Can she bring it?”

“Yes.”

“Do you remember what was on it?”

“A phone number.”

“Anything else?”

She hesitated.

“Three words.”

“What?”

IF THEY RETURN.

Deng Hu’s expression hardened.

“Who are ‘they’?”

“He didn’t say.”

“Did you call?”

“No.”

“Why?”

“Because I got sick before I could decide whether he was paranoid.”

Fair.

“Number?”

“I don't remember.”

Good.

No miracle memory.

Her sister could bring the card.

No need to force.

Lu Chen looked at Shen Yulan.

“One more question.”

“Okay.”

“The man without a badge.”

“Yes?”

“Did he touch your left wrist?”

She thought.

“No.”

“Your right?”

“Yes.”

“Where?”

“Here.”

She pointed two finger-widths above the wrist crease.

Life Meridian point.

Not ordinary pulse position.

“What did he say?”

“Nothing.”

“Did his sleeve move?”

Shen Yulan frowned.

Then:

“Yes.”

Everyone waited.

“What did you see?”

“Marks.”

Ruoxi became still.

“What kind?” Lu Chen asked.

“Three lines.”

Silence.

“Color?”

“Gray?”

“Where?”

“Inside his left wrist.”

Not Luo Jian necessarily.

The unbadged man.

Three gray lines.

Witness Physician mark?

Or copied version?

Ruoxi looked toward Lu Chen.

“Same as Luo Jian?”

“We haven’t confirmed Luo Jian has it.”

Only the Shuanghe note said if his left wrist carries three gray lines.

We had no direct observation.

Good.

Now an unknown man in Shen Yulan’s vault had three gray lines.

Could be Luo Jian?

She said middle-aged, masked, average height. Luo Jian’s age perhaps not fixed. Maybe could be. But she had met Luo Jian multiple times; she likely would recognize him even masked? Unless disguise. Better ask.

“Could it have been Luo Jian?”

Shen Yulan answered immediately.

“No.”

“Voice?”

“Different.”

“Build?”

“Different.”

Good.

Separate person.

“Did the mark look exactly like this?”

Ruoxi did not expose her own palm.

Instead, Deng Hu showed a sketch of the Quiet Heart three-line mark.

Shen Yulan looked.

“Similar.”

“Exact?”

“I don’t know.”

Good.

No forced certainty.

Someone else carried a three-line mark.

That widened the Witness system.

Perhaps more than one physician branch.

Or counterfeit.

Unknown.

Dr. Zhao looked toward Shen Yulan.

“That is enough.”

Correct.

The patient was becoming tired.

Lu Chen checked pulse again.

Normal.

“Rest.”

She nodded.

Then stopped him.

“Doctor Lu.”

“Yes?”

“If my blood is useful to them…”

Lu Chen waited.

“Can they take it again?”

“Yes.”

Honest.

Her face paled slightly.

“But?”

“You can refuse research.”

“That didn’t stop them before.”

“No.”

He did not patronize.

“So we change the practical safeguards.”

“How?”

“Your chart gets a hard consent restriction.”

Dr. Zhao nodded.

“I’ll place it.”

“Physical specimen access requires patient authorization plus two independent physicians.”

Zhao nodded again.

Su added:

“And I will issue a legal hold across Qinghe and Hanmei systems. No MC-09 material can be requested, transferred, analyzed, or copied without explicit patient consent.”

Shen Yulan looked at her.

“You can do that?”

“Yes.”

“Will it work?”

Su paused.

“Against legitimate systems.”

Good answer.

“Against whoever has been using dead credentials, we also need security.”

Deng Hu nodded.

“I’ll handle the hospital side.”

Shen Yulan looked toward Lu Chen.

“And if they come anyway?”

He answered simply.

“Call me.”

No grand promise.

No guarantee.

Just direct.

She nodded.

“Okay.”

Outside the room, Ruoxi stopped.

“Why did the unknown man ask whether Shen Yulan dreamed and whether her left hand went numb?”

That was the important question.

Jian had rejoined them.

He answered first.

“Testing whether she had a Covenant mark.”

“Maybe,” Lu Chen said.

Jian sighed.

Ruoxi ignored him.

“If they thought MC-09 was Northern House, why ask Quiet Heart symptoms?”

“Because whoever visited her may have been testing more than one hypothesis.”

Su looked toward the chart.

“Hanmei merged distinct cases.”

“Yes.”

“Cold response.”

“Memory.”

“Identity.”

“Succession.”

“Meridian conduction.”

Ruoxi’s expression sharpened.

“They were building a catalog.”

That fit.

Not one disease.

Different phenomena sharing a property:

Resonance.

Information moving through biological or spiritual systems.

Su’s blood broadcast a signal.

Shen Yulan’s blood reacted to foreign meridian residue.

Qin’s Covenant stored memory across a body and successor.

Patient Two accumulated borrowed identity through recognition.

Patient Four apparently became more persistent through recording.

Different diseases.

Different mechanisms.

Someone had been studying what they shared.

Lu Chen disliked the implication.

Jian looked toward him.

“You have the face.”

“What face?”

“The theory face.”

Lu Chen ignored him.

Ruoxi asked:

“What is the common factor?”

He answered carefully.

“Recognition.”

Silence.

Su frowned.

“Explain.”

“Su Qingyue’s blood is recognized by something external.”

Su became still.

“Shen Yulan’s sample appears to recognize foreign meridian residue.”

He looked toward Ruoxi.

“The Quiet Heart Covenant recognizes a designated successor.”

Then toward Jian.

“Patient Two became more stable every time systems recognized borrowed authority as genuine.”

And Patient Four—

he did not state the theory as fact.

But everyone understood.

Recognition might anchor it too.

Someone had built research around a principle broader than any individual condition.

Su’s expression grew cold.

“Hanmei’s Meridian Conduction Project.”

“Yes.”

“Was not merely pharmaceutical research.”

“Probably not.”

“Shen Yao knew?”

“His credential knew.”

Important distinction.

The real Shen Yao had died two years ago.

Whether he personally directed later actions was impossible.

Could have been involved earlier.

Could have been impersonated.

Do not merge.

Ruoxi looked toward Deng Hu.

“B3.”

He nodded.

“The old Hanmei server room.”

Lu Chen raised a hand.

“Not yet.”

Jian stared.

“Again?”

“We find Shen Yulan’s physical specimen first.”

“Why?”

“Because someone wanted it.”

Fair.

“And because the current system says it is still in the hospital.”

Su checked her tablet.

“Storage Unit B3-MC.”

Deng Hu looked toward Dr. Zhao.

Zhao’s expression soured.

“That is beneath the old laboratory wing.”

“Hidden?”

“No.”

“Good.”

Then:

“Mostly.”

Of course.

B3-MC was a legitimate specimen storage room.

No ancient door.

No hidden bell.

No spiritual gate.

Just cold fluorescent lighting, locked refrigerators, barcode scanners, and an overworked lab supervisor who clearly wanted everyone gone.

Lu Chen immediately liked her.

“You have authorization?”

Ruoxi handed it over.

“Patient consent?”

Dr. Zhao handed over the temporary access approval Shen Yulan had signed specifically allowing them to verify whether her stored material remained intact.

Good.

The supervisor examined everything.

Then allowed access.

No one skipped procedure.

Correct.

MC-09 had one sealed storage tray.

Physical lock.

Luo Jian’s original manual hold remained attached.

A red tag:

NO RELEASE WITHOUT PATIENT CONSENT

The lab supervisor frowned.

“This should have been reviewed months ago.”

“Why wasn’t it?” Zhao asked.

“Executive hold. Then Dr. Luo resigned. Nobody wanted responsibility.”

Very human explanation.

Sometimes bureaucracy preserved things by accident.

The supervisor opened the outer compartment.

Inside—

three specimen slots.

One.

Empty.

Two.

Empty.

Three.

Occupied.

One cryovial.

Label:

MC-09 / S.Y.

Shen Yulan.

Collection date seven months ago.

Su looked toward Lu Chen.

“That is the sample Hanmei wanted.”

“Maybe.”

The supervisor scanned it.

Barcode matched.

Chain of custody appeared intact.

But—

Lu Chen activated Life Meridian perception.

Biological sample.

Faint.

Old.

Still readable.

He had just examined Shen Yulan upstairs.

Her Origin Pulse rhythm was fresh in his mind.

He looked at the vial.

Then again.

His expression changed.

Ruoxi noticed immediately.

“What?”

“This is not Shen Yulan’s blood.”

Silence.

The lab supervisor went pale.

“That’s impossible.”

“No.”

She looked offended.

Then terrified.

“What do you mean?”

“Label matches.”

“Yes.”

“Sample doesn’t.”

Su stepped closer.

“Could degradation alter what you see?”

“Not like this.”

Dr. Zhao immediately moved to the practical question.

“Wrong blood type?”

“Test it.”

Good.

No mystical conclusion alone.

The supervisor ran an internal archive query.

Shen Yulan:

O positive.

Vial historical typing:

AB positive.

Everyone stopped.

The lab supervisor stared.

“That should have triggered rejection.”

“Unless the result was never entered.”

It hadn’t been.

The vial had never gone through standard clinical processing.

Research-only storage.

Convenient loophole.

Or deliberate.

Ruoxi looked toward Lu Chen.

“So someone swapped it.”

“Yes.”

“When?”

“Unknown.”

“Before Luo Jian’s hold?”

“Could be.”

“After?”

“Could be.”

Jian sighed.

No one teased him.

Su looked at the vial.

“Whose is it?”

“No idea.”

“Can you read Origin Pulse?”

“Faintly.”

“Recognize it?”

Lu Chen examined again.

No.

Not Pei.

Not First Infiltrator.

Not Su.

Not Ruoxi.

Not Qin.

Not Jian.

Not anyone he currently knew well enough.

But there was something strange.

Three artificial scars.

Near the left-wrist meridian pathway.

Not a Quiet Heart mark exactly.

But related architecture.

Witness-style.

Interesting.

“Could be from someone carrying a three-line medical mark,” Lu Chen said.

Ruoxi’s expression hardened.

“Luo Jian.”

“Unknown.”

“Luo Wen?”

“Unknown.”

“The masked man?”

“Unknown.”

Jian rubbed his forehead.

“I miss simple enemies.”

“So do I.”

The lab supervisor found something else.

“Wait.”

Everyone looked.

“The tray weight.”

“What?”

“When the manual hold was placed seven months ago, the unit logged physical weight.”

Good modern equipment.

“Current?”

She compared.

Different.

“By how much?”

“About twelve grams.”

That was not just a vial swap.

Something else had been inside.

Maybe a small glass ampoule.

Or paper in waterproof sleeve.

“Can we see original inventory photograph?”

“Maybe.”

She checked.

Yes.

Automatic compliance image from manual-hold placement.

Seven months ago.

Tray contained:

One cryovial.

One thin resin slide.

One folded paper strip sealed in plastic.

Now—

only vial.

Two items missing.

So someone had accessed the tray after Luo Jian’s hold despite system saying no release.

“How?” Deng Hu asked.

The supervisor checked logs.

“No electronic access.”

“Mechanical override?”

She became still.

There was an emergency key.

“Who held copies?”

“Lab director. Vice president. Facilities.”

Former vice president Luo Jian.

And others.

Deng Hu started collecting names.

Good.

Su zoomed the old inventory image.

The resin slide had a small label.

Barely visible.

W-L

Jian looked toward Lu Chen.

“Wen Luo?”

“Maybe.”

Potentially a reference sample.

The paper strip had handwriting.

Too small.

They enhanced only enough to read the first line.

COMPARE ONLY IF—

Rest obscured.

No miracle.

The original paper was gone.

So was the resin.

Whoever accessed MC-09 had not merely wanted Shen Yulan’s blood.

They wanted whatever Luo Jian had hidden alongside the case.

Perhaps a Witness Physician reference sample.

Maybe Luo Wen’s.

This changed the meaning of MC-09.

The case had become a hiding place.

The lab supervisor looked sick.

“This happened under my department.”

Dr. Zhao spoke calmly.

“You didn’t know.”

“I should have.”

“You follow the evidence first.”

Lu Chen looked toward him.

Zhao noticed.

“What?”

“Nothing.”

“You made a face.”

Apparently everyone knew faces now.

Deng Hu pulled the corridor camera archive.

Retention only six months.

The tray had been placed seven months ago.

Too late for original hold.

But the swap could have happened later.

There was one anomaly.

Four months and eighteen days ago.

One day after Luo Jian’s last confirmed public sighting.

At 2:13 a.m., B3-MC corridor camera lost feed for nine minutes.

No electronic door entry.

Then returned.

Same pattern.

Physical access.

No digital trail.

Ruoxi looked toward Deng Hu.

“Four months and eighteen days ago.”

“Yes.”

“Luo Jian vanished four months and nineteen days ago.”

One day later.

He may have returned secretly.

Or someone followed.

Unknown.

Su looked toward the cryovial.

“If Luo Jian swapped Shen Yulan’s sample himself, why?”

“To protect her,” Ruoxi said.

Possible.

“Then whose blood did he substitute?”

No answer.

Maybe his own.

Maybe Luo Wen’s.

Maybe decoy.

Need test.

Lu Chen asked for one thing.

“Do not open the vial.”

Everyone looked at him.

Jian frowned.

“We need to know.”

“Yes.”

“But?”

“If this was deliberately substituted, opening it may be the expected next step.”

Ruoxi nodded.

The false Wake Plate instruction had already taught them that.

Do not blindly follow the bait.

Su looked toward the vial.

“So we test externally.”

“Barcode history. Storage metadata. Old lab photographs. Blood type already gives mismatch.”

“Origin Pulse comparison?”

“When we have a verified reference.”

Luo Jian's.

Luo Wen's.

Masked man's.

Not now.

Good.

The vial remained sealed.

Then Dr. Zhao asked the most useful question.

“If Shen Yulan’s real sample is not here, where is it?”

Silence.

Exactly.

The sample Hanmei wanted had vanished.

Not transferred through approved channels.

No digital record.

Someone had removed it.

Seven months ago or later.

If Luo Jian moved it for protection, perhaps he documented where.

If someone else stole it—

they possessed a biological sensor that reacted to foreign meridian residue.

A tool.

A patient’s blood used as equipment.

Lu Chen’s expression cooled.

He hated that.

They returned to Shen Yulan’s room.

Lu Chen told her.

No euphemism.

“Your stored sample is missing.”

She stared.

“Missing?”

“The vial in your tray is not yours.”

Her face paled.

“How do you know?”

“Blood type mismatch.”

Good to lead with conventional evidence.

“And another method also does not match.”

She breathed slowly.

“Did they take it?”

“We don’t know who did.”

“Hanmei?”

“Unknown.”

She looked toward Su.

Su did not defend her company.

“I don’t know,” she said. “If a Qinghe or Hanmei system was involved, I will tell you when we establish it.”

Good.

Shen Yulan looked back at Lu Chen.

“What can they do with my blood?”

“Potentially test it against meridian residues.”

“Find people?”

“Maybe.”

“Track someone?”

“Possibly.”

“Open something?”

Lu Chen paused.

“No evidence.”

She nodded.

Fear controlled.

Not erased.

“Can they hurt me with it?”

“Not remotely from what we know.”

That mattered.

She exhaled.

“Good.”

Then:

“I want every remaining sample destroyed.”

Everyone went quiet.

Her choice.

Su immediately said:

“Any sample held by Hanmei or Qinghe under your identity will be frozen from use and located first. If legally and medically eligible for destruction, I’ll have it destroyed under witnessed chain of custody.”

Shen Yulan looked toward Dr. Zhao.

“What about the hospital?”

“We preserve only what is clinically required,” he said. “Anything retained solely for unauthorized research should not remain without your consent.”

She nodded.

“Then destroy those.”

“Understood.”

Lu Chen approved.

Quietly.

Her sister arrived twenty minutes later with Shen Yulan’s personal bag.

Inside—

the card.

White.

Plain.

Luo Jian’s handwriting.

Front:

IF THEY RETURN

Below:

a phone number.

Deng Hu checked.

Inactive.

No subscriber.

Back:

three lines.

Not a message.

Instructions.

1. DO NOT GIVE MORE BLOOD.

2. DO NOT LET THEM TEST YOUR LEFT HAND.

3. IF I DISAPPEAR, ASK DR. ZHAO FOR THE PAPER CHART.

Everyone slowly looked at Dr. Zhao.

He stared back.

“What?”

Shen Yulan pointed.

“You.”

“I can see that.”

Ruoxi narrowed her eyes.

“Paper chart.”

Zhao looked genuinely confused.

“I never received one.”

Lu Chen studied him.

No reason to suspect deception yet.

“Office?”

“No.”

“Locker?”

“No.”

“Home?”

“No.”

“Any sealed envelope from Luo Jian?”

“No.”

Zhao frowned.

Then stopped.

Everyone saw it.

“What?” Lu Chen asked.

“He gave me a cardiology textbook.”

Silence.

Jian stared.

“That is the most doctor way to hide something I have ever heard.”

Zhao looked offended.

“It was a good textbook.”

“When?”

“Seven months ago.”

“Before or after MC-09 hold?”

Zhao thought.

“After.”

“Where is it?”

“My office.”

Everyone moved.

Dr. Zhao’s office was painfully normal.

Desk.

Computer.

Two chairs.

Coffee.

Books.

Many books.

Jian stared at the shelves.

“This is worse than the archive.”

Zhao ignored him.

He pulled down a thick cardiology reference.

Inside the back cover—

nothing.

He frowned.

“Wrong edition.”

Of course.

Second book.

Nothing.

Third.

A hollow had been cut into the inside of the rear binding.

Inside—

a folded paper chart.

Jian looked delighted.

“Doctors are insane.”

Lu Chen ignored him.

The cover read:

MC-09 — CLINICAL ONLY

No patient name.

Inside:

Shen Yulan’s legitimate clinical results.

Then Luo Jian’s private notes.

First:

Not Northern House.

Second:

Not spontaneous Blood Calling.

Third:

Response requires proximity to preserved meridian identity material.

Then:

Potential use as detection medium creates immediate ethics problem. Do not disclose mechanism to Hanmei until consent framework exists.

Good.

Then the line that mattered:

Shen Yulan is not the research asset. Her reaction is the symptom. Find why her blood recognizes foreign meridian residue.

Lu Chen nodded.

Exactly.

Treat patient.

Do not turn symptom into tool.

Next:

Possible prior exposure?

Then:

Patient reports blood donation 2 months before admission. Donation center used equipment supplied by Hanmei Community Health Program.

Everyone became still.

So perhaps Shen Yulan’s blood was not naturally special.

Maybe she had been exposed.

“What donation center?” Ruoxi asked.

The chart listed it.

Jiangzhou East Community Blood Center.

Equipment batch number.

Hanmei-supplied.

Su’s expression became cold.

“That program predates Qinghe acquisition.”

“Yes.”

“Can we trace equipment?”

“Do it.”

She already was.

The note continued.

Hypothesis: foreign meridian residue introduced during prior blood-donation event.

Interesting.

Not inherited.

Acquired.

Like the Third Bell patient had mentioned resonance disorders arising after exposure to damaged Gate systems.

But do not jump to Gate.

Here it could be contaminated equipment.

If acquired, MC-09 demonstrates that recognition sensitivity can be induced.

That was worse.

Someone might be able to create biological detectors deliberately.

Next:

Do not repeat exposure experimentally.

Good.

Then:

Need compare with original Witness sample.

There.

W-L resin slide.

Likely Luo Wen.

Maybe.

Next note:

Father’s resin reference remains stable.

Everyone stopped.

Father.

Direct.

So W-L was almost certainly Luo Wen.

Not fully proven by initials alone—but private context strongly supported it.

Luo Jian possessed a preserved reference sample from his father.

Eighteen or more years old.

He had hidden it in MC-09 storage.

Why?

Next line:

If MC-09 reacts to Father’s reference without active spiritual stimulation, someone has altered patient biology to recognize Witness authority.

Silence.

Ruoxi looked at Lu Chen.

“That is why the unknown man asked about her left hand.”

Yes.

Maybe.

They were testing whether Shen Yulan had been engineered—or exposed—to recognize the Quiet Heart Witness system.

This was no longer just cold blood.

Someone may have been probing the Covenant through a living patient.

Next page.

Date:

Seven months ago.

Test NOT performed.

Good.

Luo Jian had refused to expose her deliberately.

Then:

Do not use patient to answer question. Find another way.

Excellent.

Next:

Shen Yao root account continues requesting transfer.

Someone wants MC-09 and Father’s reference in same facility.

There.

That was the threat.

Then:

Why?

No answer.

Another line:

Possibility: identify current Witness successor.

Ruoxi’s expression changed.

Luo Jian.

If Shen Yulan’s altered blood could react to Witness reference material, perhaps it could identify someone carrying the same succession authority.

A detector for Luo family’s hidden role.

And possibly other marked physicians.

The masked man with three gray lines may have been testing whether she reacted to him.

Did she?

Shen Yulan had said her hand burned later, not during exam.

Unknown.

The final page was handwritten more roughly.

Date:

Five months ago.

Two weeks before Luo Jian resigned.

Confirmed unauthorized access attempt.

Moved Father’s reference and instruction strip from primary tray?

Question mark crossed out.

Then:

No. Leave decoy.

Everyone stared.

Decoy.

The current cryovial.

So Luo Jian had planned something.

Next:

Real reference moved to paper archive route.

Where?

No entry.

Then:

MC-09 true sample removed from B3-MC. Patient consent does not permit continued research storage. Clinical aliquot remains in standard lab only.

Excellent.

So Shen Yulan’s research sample had not been stolen by an enemy.

Luo Jian himself had removed it.

Following her consent restriction.

Good.

Dr. Zhao checked hospital standard clinical lab records.

Yes.

A small clinical aliquot remained under ordinary patient care policy.

Not research.

No unusual transfer.

Safe enough.

Shen Yulan’s fear could be reduced.

Important.

The missing research sample had been removed correctly—though poorly documented in the compromised system.

Then what was the vial now?

The decoy.

Whose blood?

Next line answered.

Decoy from expired anonymous control stock. No patient identifier. AB+.

There.

Not Luo Jian.

Not Luo Wen.

Not mysterious.

Just anonymous control blood.

Perfect.

Lu Chen almost smiled.

Good medicine sometimes eliminated exciting theories.

Jian looked disappointed.

“That is boring.”

“Yes.”

“Good?”

“Very.”

Ruoxi laughed softly.

So the missing items from the tray—

Luo Wen’s resin reference.

Instruction strip.

Those were the real target.

And Luo Jian had moved them before disappearing.

The chart continued.

If I fail to return, Dr. Zhao unknowingly holds route to next record.

Zhao looked offended.

“Unknowingly?”

Jian smiled.

“Accurate.”

“Quiet.”

Next:

Do not put location in electronic record.

Then:

Route key: page 914.

Everyone looked at the cardiology textbook.

Zhao opened page 914.

A chapter on conduction abnormalities.

One paragraph underlined.

Not medical significance.

First letters of five sentences.

Ruoxi read them.

R I V E R

River.

Jian groaned.

“That is terrible.”

Zhao looked defensive.

“I did not write it.”

Next clue.

Margin notation:

17 / EAST

River 17 East.

Could be address.

Locker.

Pier.

Ward.

Need not guess.

Deng Hu searched ordinary property and hospital references.

Several results.

Then one matched Luo Jian’s old parking expense claims.

East River Storage, Unit 17.

Commercial self-storage facility.

Still active.

Rented under—

not Luo Jian.

Under a company.

Which?

Deng Hu looked up.

“Remembrance Holdings.”

Everyone became silent.

The Qin family trust.

Ruoxi stared.

“Our trust?”

“Yes.”

“Who authorized?”

Deng Hu checked.

“Qin Zhenguo.”

Date:

Twenty-seven years ago.

The trust had maintained Unit 17 continuously.

No one in current Qin administration knew why.

Another mortal hiding place.

No spiritual archive.

No hospital network.

Just a storage locker.

Again.

Pei’s philosophy.

Stupid systems.

Useful.

Ruoxi called Qin Zhenguo.

He answered:

“What now?”

“East River Storage. Unit 17.”

Silence.

No heart monitor here, but Dr. Zhao had remote data.

Heart rate:

Stable.

“Do you remember it?” Lu Chen asked.

Qin did not force.

Good.

After a few seconds:

“No.”

No change.

“Then we do not push.”

Qin sighed.

“What is there?”

“Possibly Luo Jian’s next record.”

“Why would my trust own it?”

“Twenty-seven years.”

Silence.

The same year as Luo Wen’s supposed death.

Qin’s expression through video changed slightly.

But heart remained stable.

“Do you want to go?” Ruoxi asked.

Qin looked at Lu Chen.

“No,” Lu Chen said.

Qin stared.

“You didn’t even let me answer.”

“Your cardiologist agrees.”

Dr. Zhao nodded.

“Strongly.”

Qin sighed.

“Fine.”

Progress.

Before leaving, Lu Chen returned to Shen Yulan.

He gave her the corrected information.

“Your research sample was removed by Luo Jian under your consent restriction.”

Her shoulders dropped.

“So they don't have it?”

“We cannot guarantee no unauthorized copy ever existed.”

Honest.

“But the sample we thought was stolen was deliberately removed by him.”

“And the vial downstairs?”

“Anonymous control blood.”

She laughed once.

Relief.

“Good.”

“Yes.”

“What about the clinical sample?”

“Ordinary medical storage. You can discuss retention with Dr. Zhao.”

She nodded.

“Then I want anything not medically necessary destroyed.”

“Understood.”

Su had already prepared the paperwork.

Not automatic.

For Shen Yulan to review and sign.

Good.

Before Lu Chen left, she asked:

“Doctor Lu.”

“Yes?”

“Was Luo Jian a good doctor?”

Lu Chen paused.

Complex question.

“He made at least one decision for Qin Ruoxi without her consent.”

Shen Yulan waited.

“He also protected your consent when others ignored it.”

“So?”

“So people are not one decision.”

A pause.

“I don’t know him well enough to give you a verdict.”

She nodded slowly.

“That seems fair.”

Good.

East River Storage looked disappointingly modern.

Concrete.

Roll-up doors.

Security cameras.

Receptionist eating sunflower seeds.

No ancient bells.

Jian looked around.

“I like it.”

“Why?”

“No underground temple.”

Deng Hu checked Unit 17 paperwork.

Current payment automated through Remembrance Holdings.

Access log:

No electronic entry in eleven months.

But mechanical key allowed.

Old unit.

No interior camera.

Of course.

Ruoxi possessed corporate authorization.

Still, they called management.

Documented entry.

Witness present.

Boring procedure.

Lu Chen approved.

The lock opened.

Inside—

boxes.

Many boxes.

Old office furniture.

A broken chair.

Two metal filing cabinets.

One refrigerator unplugged.

Jian stared.

“This is the secret?”

“Probably.”

“Very disappointing.”

“Good.”

They searched carefully.

No spiritual perception first.

Ordinary labels.

Qin family tax records.

Old hospital invoices.

Eastern River maintenance receipts.

Nothing.

Then Ruoxi opened a small cardboard box labeled:

CARDIOLOGY — OBSOLETE

Inside—

three paper ECG rolls.

A stethoscope.

A silver ring.

Three engraved lines.

Everyone became still.

Luo Wen’s Witness Physician ring.

Maybe.

Could be.

Do not assume.

Beside it—

a sealed resin slide.

Label:

W-L

There.

The missing reference.

Luo Jian had moved it here.

Good.

Also a folded strip of paper.

The missing instruction.

Ruoxi did not open it yet.

She looked toward Lu Chen.

“Patient?”

“No patient involved.”

“Then?”

“Open carefully.”

She put on gloves.

Unfolded.

Luo Wen’s handwriting.

Older.

First line:

If my son wakes the Keeper’s successor without a physician present, he is frightened.

Silence.

Not evil.

Frightened.

Second:

Fear does not make the decision correct.

Lu Chen’s expression changed slightly.

Same philosophy.

Third:

Do not punish the successor for his fear.

Ruoxi read that twice.

Then:

Do not excuse him either.

Good.

Very good.

Jian exhaled.

“I like his father.”

“Maybe.”

Jian looked at Lu Chen.

“Potentially.”

Xiaoxiao had infected even absent people.

The next paragraph:

Luo Jian carries the Witness Physician succession mark on his left wrist.

Confirmed.

I activated the first line when he was twenty-one. He did not consent because I told myself he was too young to understand.

Ruoxi’s expression changed.

Parallel.

Qin had marked her at eighteen without full explanation.

Luo Wen had done the same to Luo Jian.

Intergenerational secrecy.

Same mistake.

I was wrong.

Simple.

Then:

If he later makes the same choice for someone else, do not tell him he inherited the mistake.

Pause.

Tell him he repeated it.

That line landed.

Inheritance explained.

It did not absolve.

Good.

Then:

The Witness Physician exists to protect the Keeper from the Covenant and the Covenant from those who would exploit it.

He does not own the Keeper.

He does not own the successor.

Exactly.

Ruoxi closed her eyes briefly.

Then continued.

Final section.

If Luo Jian disappears after activating a successor, check whether his own mark was awakened first.

There.

The note from the package had warned:

HE LEFT BECAUSE SOMEONE ELSE WOKE HIS MARK.

Now older instruction supported the relevance.

A Witness successor who dreams may begin remembering cases he never personally treated.

Procedural/inherited memory.

Similar but not identical to Qin succession.

Then:

The first remembered case will usually be the last unresolved patient of the prior Witness Physician.

Everyone became quiet.

Luo Wen’s last unresolved patient.

Which?

The Fourth Patient?

Maybe.

No assumption.

Next line:

If he remembers Patient Four, do not let him approach Eastern River.

Silence.

Lu Chen looked toward the old clinic in his mind.

Lower east wall.

No opening.

Good.

Then:

If he remembers MC-09, he is not remembering my case.

Interesting.

MC-09 did not exist eighteen years ago under that number.

So this part had been added later?

Different ink.

Yes.

Recent.

Luo Jian’s handwriting.

Not Luo Wen.

Two eras on one instruction strip.

Luo Jian added:

MC-09 is mine.

Meaning his patient.

Not ownership.

Responsibility.

Then:

I woke Ruoxi because I was afraid Qin Zhenguo would die before I found Lu Chen.

There.

Direct.

I was wrong to do it without asking her.

Ruoxi became completely still.

No defense.

No excuse.

Then:

Afterward, my own mark woke.

Silence.

There.

Someone activated Luo Jian’s Witness succession mark after he activated Ruoxi.

Next:

I began dreaming of my father’s last patient.

Everyone stopped breathing for a second.

Then:

Not Patient Four.

Good.

Important.

Next line:

Patient Three.

The unidentified child from Eastern River.

There.

A new connection.

Luo Jian's first inherited procedural memory concerned Patient Three.

The child.

Not Patient Four.

That preserved separation.

Then:

The child survived the fire.

Silence.

Jian leaned closer.

Lu Chen read on.

My father moved the child before his staged death.

So four years later.

Interesting.

I do not know the child’s name. The Covenant removed it from my dream every time I approached it.

Then:

But I know where the child was sent.

Everyone stared.

Next line:

QIN FAMILY CARE.

Ruoxi’s expression changed completely.

“What?”

The Qin family had hidden a child.

Thirty-one years ago.

A patient from Eastern River.

Could that connect to the Qin family’s current symptoms?

Maybe.

Do not jump.

Next:

Not adopted. Not blood. Protected under ordinary charity records.

Good.

No surprise secret Qin heir.

Then:

If you want to understand why the Qin family began getting sick, find what happened to Patient Three after leaving their care.

There.

The mini-arc snapped back into focus.

Patient Three.

A child placed under Qin family protection.

Not biologically Qin.

But possibly the origin of whatever later affected the family.

Ruoxi looked toward Lu Chen.

“Grandfather never mentioned a child.”

“His memory is sealed.”

“Yes.”

“Do not ask tonight.”

She nodded.

Good.

The final line:

I went to find Patient Three.

Then:

That is why I disappeared.

Silence.

Luo Jian had not simply run from the hospital.

He was following the inherited memory of his father’s last unresolved patient.

And if the note was genuine—

Patient Three was the key to understanding the Qin family’s hidden illness.

Jian slowly exhaled.

“So MC-09 led us to Luo Jian.”

“Yes.”

“Luo Jian led us to Patient Three.”

“Yes.”

“Patient Three leads back to the Qin family.”

“Yes.”

He looked almost pleased.

“That is annoyingly coherent.”

“Good.”

Ruoxi did not smile.

She was staring at the words:

QIN FAMILY CARE

Then:

“Patient Three was a child.”

“Yes.”

“Thirty-one years ago.”

“Yes.”

“Protected by my family.”

“Yes.”

“And Grandfather doesn’t remember.”

“Not safely.”

Her voice lowered.

“If that child harmed my family—”

Lu Chen stopped her.

“We do not know that.”

She looked at him.

“The note says find what happened after leaving our care.”

“Yes.”

“Meaning something happened.”

“Yes.”

“To us.”

“Possibly.”

She sighed.

He did not smile.

This time the word mattered.

Su, who had remained quiet, looked toward the resin slide.

“What about Luo Wen’s sample?”

“Preserve it.”

“For future Origin Pulse verification.”

“Yes.”

“If we find Luo Wen.”

“Or someone claiming to be him.”

Good.

No one touched the silver ring.

No one activated anything.

No one opened a new door.

Progress.

Deng Hu documented every item.

Photographed.

Bagged.

Chain of custody.

Ordinary systems.

Boring.

Useful.

At 6:11 p.m., Lu Chen finally returned to the clinic.

Xiaoxiao was sitting behind the consultation table.

Again.

A new sign had appeared beneath:

PATIENTS ARE PEOPLE

Now another line:

PEOPLE ARE NOT KEYS

Lu Chen stopped.

Xiaoxiao looked up.

“Good?”

He stared at the sign.

Patient Two.

Su Qingyue.

Qin Ruoxi.

Shen Yulan.

Luo Jian.

Every conspiracy they had uncovered eventually turned a person into a door, a sample, an authority, a signal, a successor, a tool.

“Yes.”

Xiaoxiao smiled.

“Can stay?”

“Yes.”

“Forever?”

“We’ll see.”

“Fine.”

He stared.

She giggled.

During dinner, Xiaoxiao asked:

“Did you find Patient Nine?”

“Yes.”

“Was she sick?”

“She is recovering.”

“Did you help?”

“She was already my patient.”

“Did bad people take her blood?”

Lu Chen paused.

“Someone tried to use it without permission.”

Xiaoxiao frowned.

“That’s stealing.”

“Yes.”

“Did you get it back?”

“Her important clinical sample is safe.”

That was the simplest accurate answer.

She nodded.

Then:

“Who next?”

Lu Chen looked toward the paper note in his bag.

Patient Three.

A child who survived Eastern River.

Protected by the Qin family.

Later gone.

Somehow connected to the illness now appearing around the family.

“We find another old patient.”

“Kid?”

“At the time.”

“How old now?”

Lu Chen calculated roughly.

If the child had been perhaps school-age thirty-one years ago—

late thirties or forties now.

But exact age unknown.

“Adult.”

Xiaoxiao nodded.

“Then charge fifty.”

Lu Chen stared.

Business returned quickly.

At 9:46 p.m., Qin Ruoxi called.

Her voice was quiet.

“Grandfather remembered something.”

Lu Chen stood.

“Did anyone push?”

“No.”

“Heart?”

“Stable.”

“What?”

“He saw the phrase ‘Qin Family Care’ in the photograph of Luo Jian’s note.”

That alone triggered an ordinary fragment.

Not deep sealed recall.

“Then?”

“He remembered a place.”

Lu Chen waited.

“Not the ancestral house.”

“Where?”

“An old children’s convalescent home the Qin family funded.”

Silence.

“Name?”

Ruoxi answered:

Spring Willow House.

“Still exists?”

“No.”

“When closed?”

“Twenty-four years ago.”

Seven years after Eastern River.

“What happened to records?”

“Most transferred to Qin Medical Center’s predecessor charity office.”

“Most?”

“One child’s discharge file is missing.”

There.

“Patient Three?”

“We don’t know.”

Good.

“Anything else?”

Ruoxi’s voice tightened.

“Grandfather remembers visiting one child there.”

“Name?”

“No.”

“Sex?”

“Boy.”

Good.

Not Jian’s infant girl.

Not Xiaoxiao.

Different timeline and sex.

“Age?”

“He thinks around eight or nine.”

Good.

“Condition?”

“That’s the part that matters.”

Lu Chen waited.

Ruoxi continued:

“Grandfather says the boy was healthy.”

Silence.

“Then why convalescent care?”

“He wasn’t there because he was sick.”

Lu Chen’s expression changed.

“Why?”

A pause.

“Because everyone around him was.”

There.

The Qin family hidden illness.

Not necessarily inherited.

Not necessarily from Covenant.

Perhaps exposure.

Patient Three.

A child who appeared healthy while people around him developed symptoms.

Ruoxi continued:

“Grandfather remembers three staff members fainting in the same month.”

“What else?”

“One developed memory gaps.”

“Another?”

“Heart rhythm problems.”

Exactly the Qin symptoms.

Lu Chen became still.

“Did the child cause it?”

“We don’t know.”

Good.

“Grandfather says Luo Wen told him something.”

“Exact words.”

Ruoxi repeated:

“Do not call the child contagious until we know what is being transmitted.”

Silence.

Not disease necessarily.

Maybe resonance.

Maybe recognition.

Maybe something else.

Then:

“People around him are not catching an illness.”

A pause.

“They are beginning to remember something that never happened to them.”

Lu Chen’s eyes hardened.

Borrowed memory.

But not Patient Two.

Different mechanism.

Patient Three.

A healthy child.

People around him developing fainting, cardiac changes, numbness, memory fragments.

The same symptom cluster now appearing in the Qin family.

Perhaps not because of inherited blood.

Perhaps because the Qin family had once cared for a patient carrying something that could persist through memory or recognition.

Ruoxi’s voice came softly through the phone.

“Lu Chen.”

“Yes?”

“Grandfather says the boy disappeared from Spring Willow House.”

“When?”

“Twenty-four years ago.”

“Taken?”

“Unknown.”

“Run away?”

“Unknown.”

“Dead?”

“No record.”

Then the final fragment:

“Before the boy disappeared, he left a sentence carved beneath his bed.”

Lu Chen waited.

Ruoxi read it from the old maintenance photograph Deng Hu had just found.

I REMEMBER YOU EVEN IF YOU NEVER MET ME.

The clinic became very quiet.

Lu Chen looked toward the sign Xiaoxiao had taped beneath the consultation fee.

PEOPLE ARE NOT KEYS

Patient Three had survived.

And somewhere between a burned clinic and a forgotten children’s home—

someone had turned memory itself into something that could travel between people.
