Hello, Mr. Major General

Chapter 1729: Believe It or Not

This kind of experiment was very boring, and most of it was done by machines. However, Lu Jin wanted to show Gu Nianzhi what he was capable of. He did it himself, and Gu Nianzhi watched with relish.

When she heard her phone ring and saw that it was Xie qingying calling, she almost had the urge to hang up.

Nevertheless, for He Zhichu’s sake, she thought about it and answered the call.

“Gu Nianzhi, did I interrupt you and Mr. Peter for the Lantern Festival?” Xie Qingying asked first, her voice a little stiff.

Gu Nianzhi frowned. “There’s nothing going on between Mr. Peter and me. We’re just friends. Why would we celebrate the Lantern Festival Together?”

She really hadn’t spent the lantern festival with Peter…

Xie Qingying felt very uncomfortable. Countless speculations swirled in her mind. In the end, she suppressed her emotions and said in a low voice, “Young Master He went to deliver something to you today. Someone secretly took photos of the two of you.”

Gu Nianzhi was rendered speechless.

“Secretly? who has so much free time?” Gu Nianzhi was speechless. “It’s the 15th of the first lunar month today!”

Secretly taking photos outside of her home during the holidays?

What the hell!

“Yes.” Xie qingying nodded lightly, “Who else? Wen Shouyi. She sent me a photo. I was so angry that I blacklisted her and forgot to save the photo. She then withdrew it. I don’t have any evidence. It doesn’t matter if you believe it or not, I’ve already informed you.”

Gu Nianzhi’s lips twitched. Wen Shouyi was quite a character. She had kept such a close watch on her. Did she know that she was testing her and her parents’DNA?

Gu Nianzhi rolled her eyes and asked, “Is it convenient for you to talk?”

“I’m in the car.”Xie qingying looked outside the car. It was late and she was almost home.

“Oh, let’s text then.” Gu Nianzhi beamed. “You can be more specific.”

“Is it inconvenient for you to talk?” Xie qingying couldn’t help probing. “Am I still disturbing you?”

“No, I’m watching someone do an experiment. It’s very interesting.” Gu Nianzhi smiled and hung up. She then sent a text to Xie Qingying.

Gu Nianzhi replied, “When did Wen Shouyi send you a photo? Can you give me a rough description of what it looks like?”

Xie Qingying heard that Gu Nianzhi was watching someone do an experiment and didn’t believe it at all.

Where was she going to watch the experiment on the 15th day of the Lunar New Year?

But she didn’t say much and only sent Gu Nianzhi a screenshot of Wen Shouyi retracting the photo.

Gu Nianzhi looked at the time Wen Shouyi retracted the photo. “There’s still time. I’ll teach you a way to show the photo that the other party has already retracted.

This was because the action of taking the photo back did not mean that the other party had really deleted the photo from your phone at the right time. Instead, they had replaced the previous photo with an established message.

The photo that the other party had sent was actually still in the cache on your phone. Most people did not know how to pull the photo out of the cache.

The photo would only truly disappear after the phone had cleared the cache.

Gu Nianzhi noticed that Wen Shouyi had only taken a few minutes to retrieve the photos. Xie Qingying’s phone must still have photos of Wen Shouyi in the cache.

Xie Qingying was especially surprised. “The retraction message can still be recovered?!”

Gu Nianzhi nodded with a smile. “Yes, of course.”

She then sent Xie Qingying a series of instructions to follow her instructions.

Xie Qingying used an iPhone, so it was more difficult to retrieve photos from the cache than it was on Android.

However, with Gu Nianzhi around, these were not a problem.

While she was there, she had learned a lot of practical hacking knowledge from Zhao Liangze.

Jailbreaking an iPhone was just a normal operation for hackers.

Xie Qingying followed Gu Nianzhi’s instructions and operated the phone step by step, as if she had opened the door to a new world.

When she pulled the two photos that Wen Shouyi had taken back from her phone, she was already full of admiration for Gu Nianzhi.

This little girl was simply too amazing.

Her beauty was complemented with wisdom. It was no wonder He Zhichu still had feelings for her.

Xie Qingying was determined to keep her distance from Gu Nianzhi. With mixed feelings, she saved the two photos on her phone and forwarded them to Gu Nianzhi.

She then replied: “I still have something to do. I just wanted to remind you.”

“Happy Lantern Festival.”

Gu Nianzhi also replied, “Happy Lantern Festival.”

Xie Qingying closed the chat and looked up to see that the car had stopped at her door.

“Qingying, are you okay?” Xie Qingying’s best friend got out of the driver’s seat, opened the car door for her, and helped her out of the car.

Xie Qingying’s drunkenness was almost gone. She smiled and nodded at her best friend. “Thank you. Go and accompany your boyfriend. I’m going back to sleep.”

Her best friend sighed. “Let me help you in before you leave.”

Xie Qingying was helped into the house by her best friend. After washing up, she went to bed.

However, she could not sleep and was in a state of excitement.

After her best friend left, Xie Qingying took out her phone and began to call He Zhichu.

However, He Zhichu had been working all this time and did not pick up her call.

…

While resting her chin on her hand, Gu Nianzhi looked at the photos on her phone in a daze.

Lu Jin set up the equipment and had them start the DNA sequencing test for Wen Dayou and Liang Meili.

He turned around and saw Gu Nianzhi holding her phone in a daze.

“What’s wrong? who was on the phone just now?” Lu Jin was very focused when he was working, so he paid little attention to the things around him.

Gu Nianzhi frowned and raised her head. She showed the photo on her phone to Lu Jin and said in confusion, “Look, how did you take this secretly? I can see that the quality of the photo is quite good, but I can’t tell where the person who took it is at all.”

If she could find the location of the person who took the photo and check the nearby surveillance cameras, she should be able to trace it back to Wen Shouyi and find Satoshi Saito.

Although she looked left and right, she still could not determine the location of the person who took the photo.

Lu Jin looked at it and said, “From the angle of the photo, it was taken from the top of the side. This angle is a little strange, and it doesn’t look like an ordinary digital camera.”

He pointed to Gu Nianzhi’s computer and said, “Send me the photo, I’ll analyze it for you.”

“Okay!” Gu Nianzhi cheered up and quickly sent the two photos to Lu Jin.

Lu Jin turned on his desktop computer, which was comparable to a central server, and opened the photo with a mathematical analysis software.

Soon, the flat photo was three-dimensional on Lu Jin’s computer screen.

People, objects, and the surrounding buildings were all clearly displayed on the screen.

Lu Jin pointed at the picture on the computer and said, “With this model, you can deduce the exact location of the camera from the angle of the character’s display.”

“You can deduce that?!” Gu Nianzhi was extremely surprised. Her black pupils seemed to be able to speak as she looked at Lu Jin.

As Lu Jin smiled proudly, he clicked his mouse twice on the computer screen. “Of course I can deduce that.”

“Do you know a gun ballistics expert? They can tell what type of bullet it is and what type of gun it came from from just by looking at a bullet hole.”

“An even better ballistics expert can even pinpoint which gun the bullet came from.”

“We used the same principle to calculate the location of the person who took the photo.”

“This person took the photo with an optical lens, and the photo was also developed with film, making it more difficult to track down.”

“If he used a digital camera and the photo was a digital image, I would be able to pinpoint his location in less than a second.”

Lu Jin shook his head regretfully. “But now, I have to model his photo and calculate from the angle of the light rays in order to find the end point of the light rays, which is where the person took the photo.”

“Don’t you have surveillance cameras in the residential area? Can you pull them up and take a look?” Gu nianzhi quickly said, “Maybe he’s in the surveillance.”

Lu Jin shook his head. “You can look at the surveillance cameras, but don’t get your hopes up. Looking at the angle and the texture of the photo, I feel like he used a telephoto lens to take the photo from a tall building in the distance.”

The surveillance cameras around the residential walls could not see this person at all.

The optical lens also avoided being scanned by electromagnetic waves, so conventional methods would not be able to find this person.

Only Lu Jin, who used complex three-dimensional analytic geometry and linear algebra to perform modeling and calculation, could accurately find his location.

Gu Nianzhi watched in admiration as Lu Jin programmed and calculated on the computer.

Half an hour later, Lu Jin finally finished running his program.

He pointed at the window of a high-rise building on the 3D model with his mouse. “It’s here. That person used a telephoto lens to secretly take photos of you.”

As he spoke, Lu Jin wrote down the floor and house number of that person. “Find He Zhichu and have him arrested.”

Gu Nianzhi nodded happily and immediately called He Zhichu.

At this time, He Zhichu’s work had just come to an end.

In order not to be disturbed, he had set his phone to silent mode.

As soon as he picked it up, he realized that there were a lot of missed calls in front of him. The most recent missed call was actually from Gu Nianzhi.

He Zhichu was slightly startled and immediately called Gu Nianzhi back.

Gu Nianzhi was about to call again when she realized He Zhichu had already called. She quickly said, “Young master he, are you still working? Did I disturb you?”

He Zhichu grinned. “I just finished. What’s the matter? is something the matter?”

“Yes, something the matter.” Gu Nianzhi replied and sent He Zhichu an address, a set of coordinates, and two photos from Xie Qingying.
