“Though I’ve learned of the symptoms and formula from you, we haven’t seen any patient with our own eyes. So I can’t guarantee that I’ll come up with a solution. Besides, the plague has spread to the entire state. I’m afraid it will be difficult to deal with it.”

Lin Mengya was worried about it as well.

According to Long Tianyu’s words, she could go to the Yun State, but she couldn’t go to the core places.

That was to say, she could only deal with the aftermath or take precautions outside the core places.

The contribution she could make to the epidemic area would be greatly weakened.

“You’re right, but I’ve once seen a patient who got poisoned by a similar poison. And I think this poison may be closely related to the one in the epidemic area. If we work on the solution together, Mr. Baili, will the success rate be higher?”

The patient she referred to was Xiao Yixin.

He had arrived at Lin Mengya’s mansion long ago. With her token, he had been treated very well.

Though he said he had let it go, Lin Mengya believed that he had had enough of suffering from the poison, given that he once was such a big shot.

It was just that he had always been a quiet gentleman, so he wouldn’t talk about it if Lin Mengya didn’t mention it.

“Of course! Bring him here, hurry up. This time, I’ll go with you. I really want to meet this vicious schemer in person!”

Baili Rui’s eyes were shining. It was hard to tell whether it was because of excitement or anger.

Lin Mengya was stunned for a moment. She realized that her teacher seemed to have become more vivacious.

She looked at him with a strange expression and wondered if falling in love would change a person’s personality.

It reminded her of Long Tianyu, who would chat and joke with her recently.

She nodded heavily in her heart. “It seems it will.”

“Okay. I’ll go find him right now. Please wait for a moment. He is in my mansion now.”

In fact, it didn’t take long for Lin Mengya to find Xiao Yixin.

When Long Tianyu asked her where she was going, she just replied that Baili Rui wanted her to bring Xiao Yixin over so that they could discuss the matter about the Immortal Powder.

It made sense. Since the current Immortal Powder was made based on Baili Rui’s old formula, Long Tianyu certainly would recover faster with his help.

When Lin Mengya brought Xiao Yixin to the stone room eagerly, to her surprise, her teacher and Long Tianyu were not arguing somehow.

“I’ll have to trouble you for all this, Mr. Baili.”

Long Tianyu stood up, cupped his hands, and said to Baili Rui seriously.

“Don’t worry. I know what to do. You’re occupied with numerous affairs every day, Prince Yu, so leave these trivial things to me.”

Baili Rui also had a serious expression on his face. The two of them bowed to each other in a natural and unrestrained manner.

Standing in front of Lin Mengya, Long Tianyu stretched out his hand and gently stroked the messy long hair beside her ear.

“Don’t come back too late.”

Lin Mengya nodded. She knew that Long Tianyu was worried about her condition.

However, since Baili Rui was there and Lin Mengya was just his assistant, it wouldn’t take her long.

After a quick glance at Xiao Yixin, Long Tianyu left the stone room quickly.

However, Lin Mengya, who had always been sensitive, felt that there seemed to be something weird about these two people.

However, she didn’t know what exactly it was.

“Sit down.”

Her teacher said coldly to Xiao Yixin, so different from when he talked to her.

Xiao Yixin immediately bowed to Baili Rui as a junior before sitting cautiously on the chair in front of him.

“Mr. Baili, this is Xiao Yixin. His family and my family are friends for generations, and he is my brother’s friend. As you can see, the poison has caused his muscle to atrophy and shift, and that’s why he becomes what he looks like now.”

After Baili Rui heard those words, his sharp gaze fell on Xiao Yixin and then on Lin Mengya.

“You go out first, Mengya. I want to check up on him and you’re a girl, so you need to go out for a moment.”

Lin Mengya was surprised at the words. Back when she was an intern, she had seen all kinds of bodies.

She had studied the structure of the human body thoroughly in the anatomy class.

She wanted to refuse but surrendered in the end as his teacher was glaring at her with a serious look.

She had no choice because a student in ancient times must follow his teacher’s order.

Though the door was ajar and Lin Mengya was bored, she wouldn’t be as stupid as to peep into it because there were guards around.

Standing in the passageway, she listened carefully to what was going on inside the room.

In the beginning, everything seemed to be going well, but gradually—

“Ahh—it hurts! Mr. Baili…I…”

“Huh?” Lin Mengya widened her eyes. “It’s just a check-up. Why did Xiao Yixin scream so shrilly?”

“Be brave! To a real man, the pain of this level is nothing. If it weren’t for the sake of Mengya, I wouldn’t have even bothered to treat you.”

On hearing Baili Rui’s scolding voice, Xiao Yixin couldn’t help but let out a low groan, and his scream of pain gradually weakened.

It was just that…

“Hiss… Mr. Baili, what are you doing with the knife?”

“What else can I do with it? Of course, I’m using it to check your physical condition. As a man, it’s not a big deal to have a small cut on the body.”

Xiao Yixin fell silent again, probably because he was scared.

Lin Mengya was very curious now. She wondered if her teacher’s examination method was different from that of hers.

It was natural that she would become curious. She had been doing physical examinations through the Shen Nung system, so she almost forgot some ancient examination methods if her teacher didn’t mention them.

The check-up finally ended with Xiao Yixin’s yelling voices.

“You can come in.”

Lin Mengya immediately opened the door and walked into the room after hearing her teacher’s words.

Xiao Yixin, who was still sitting on the chair, looked a little frightened. Baili Rui, however, looked displeased while frowning.

“Huh? Is it because the poison in Xiao Yixin’s body too hard to deal with?”

“Oh, coward, it’s just a check-up. Why did you scream so miserably? People might think I was murdering you!”

Baili Rui glared at Xiao Yixin with disdain. The latter showed a bitter smile, not daring to argue.

Lin Mengya felt that the atmosphere was a little strange, but she didn’t think much about it. After all, her teacher was the Saint of Poison, so his technique was naturally different from that of an ordinary person.

“How is it, Mr. Baili? Do you know how to deal with the poison inside Brother Xiao?”

On hearing the question, Baili Rui put on a serious look as he replied, “I had a look, and his own flesh and muscle are fine. I left a shallow cut on his body, but there was no blood flowing out and he didn’t feel any pain, which showed that his original skin has been covered by another layer of new human skin. Because of that, he looks so horrible now.”

The answer was totally beyond Lin Mengya’s expectation. She was still confused because it was not easy for new human skin to grow.

If the poison had this magical effect, wouldn’t the life of those burn patients be full of hopes?

“Even Mr. Baili hasn’t seen this poison before. What is it exactly?” Lin Mengya wondered to herself.

“It seems to be a kind of venomous insect called Venomous Armored Insect. This coward wasn’t poisoned too seriously, so only part of his skin has been covered by the new skin. Back then, I was lucky to meet a patient who was poisoned very seriously. He was 1.8 m tall but ended as a ball-shaped man about 0.2 m tall.”

“Venomous Armored Insect?” Lin Mengya did not expect that there was such a strange kind of venomous insect in the world.

“Does it mean that the poison that caused the plague has something to do with this insect?”

This was what Lin Mengya was concerned about the most, and what her teacher said next enlightened her.

“Not really. If people accidentally swallowed the powder ground with these insects, their meridians would shrink, and if the worst comes to the worst, their bones would atrophy, exactly the same as the symptoms you told me. But I think someone must have processed it, otherwise, it wouldn’t have caused a plague.”

Having found the crux of the plague, Lin Mengya breathed a sigh of relief.

She turned around and saw that Xiao Yixin was looking at her with inquiring eyes. Since he had done her such a big favor, she thought she should return the favor.

“Mr. Baili, can you cure Brother Xiao?”

Baili Rui looked at Xiao Yixin, and a sly smile suddenly appeared on his face.

“Yes, but this would make this coward suffer. Not everyone could make it after taking my medicine.”

Baili Rui thought that Xiao Yixin would run away after hearing his words.

To his surprise, Xiao Yixin looked at him with gratitude and bowed to him before saying, “Thank you, Mr. Baili. I have nothing to return the favor, but I’m willing to do anything for you even at the cost of my life.”

“Humph, your life is so trivial, and your flesh is not nutritious enough to be the material of my poison. Get lost. I’ll come to treat you tomorrow, and you can rest assured that you will recover fully with me there!”

Baili Rui’s tone was particularly cold.

Xiao Yixin couldn’t help shivering. He then smiled bitterly.

“I’ll not bother you any longer, Mr. Baili. I’ll go back for a rest now. Long Tianyu is still waiting for me, and if I go back late, he will be worried about me.”

Baili Rui waved his hand and walked into his medicine room fast.

Lin Mengya and Xiao Yixin walked out side by side. Under his black cloak, Xiao Yixin’s eyes regained their usual color.

“Brother Yixin, I have to apologize on behalf of my teacher. He is a cranky man, but his medical skills are beyond doubt. He is the best poison-maker and physician in the world.”

Lin Mengya was not bragging.

She didn’t know this before until she heard some legendary stories about her teacher from Zuo Qiuyu.

At the age of 15, her teacher was recognized as the best poison-maker and physician in Dajin.

Lin Mengya believed that his medical skills must have reached a very high level after years of hard work.

“It’s okay. I brought all this upon myself. Mr. Baili is a straightforward man. I believe that your father and brother would feel relieved after learning that you’re learning from Mr. Baili.”

Xiao Yixin didn’t tell Lin Mengya what had happened to him, but she could roughly guess it.

She stuck out her tongue in secret. She knew that Long Tianyu must have told Baili Rui on her when she went to look for Xiao Yixin.
