Starting as a Wallfacer, his defection to the Three-Body Problem shocked the world.

While the Zhiyuan Star project was under construction, at the Red Coast Base...

A disheveled man was standing outside Lin Xuan's office.

"Wei Cheng, husband of former ETO member Shen Yufei, is currently a technical advisor for PES."

Lin Xuan looked up at the unkempt man in front of her and gestured for him to sit down.

The latter then entered Lin Xuan's office. He looked around and found that the walls of the entire office were completely empty, and there were very few decorative items on the desk.

"Mr. Wallfacer seems to really like this minimalist style of decor."

“Simplicity represents stability, just like the theorems in mathematics,” Lin Xuan said.

Upon hearing this, Wei Cheng reached out and brushed the hair that was obstructing his vision upwards a few times so that he could see the man's face clearly.

"I thought you would be like other big leaders, enjoying decorating your office with landscape paintings and calligraphy."

Lin Xuan smiled and shook her head.

"What's the point of making those landscape paintings and calligraphy that even they themselves can't understand? It's just a way for some people with no knowledge to show off. The more a person lacks something, the more they flaunt it. I don't care about those things."

“At least it should be made more impressive, after all, I heard this is the center of your team,” Wei Cheng said.

Upon hearing this, Lin Xuan shook her head slightly.

"No, you're wrong. Red Coast Base is not the center of our team."

Shock level from Wei Cheng +1.

"what is that?"

“The core of our team is neither this Red Coast base nor the Reach in space, but myself.”

Lin Xuan pointed to himself.

"Where I am, that is the center."

Wei Cheng smiled; he couldn't remember the last time he had shown such an expression.

“I’m not a very talkative person because I’m too lazy to talk to others, but Mr. Lin Xuan, I think we should get along very well.”

"my pleasure."

As Lin Xuan spoke, she pointed to the tea and snack robot next to her.

"There's coffee and drinks available, help yourself."

Wei Cheng bent down and took out two paper cups from the cabinet. He poured a glass of water for himself and Lin Xuan, and then sat down opposite Lin Xuan.

"I had heard Professor Wang Miao mention you before. He said you are a very creative person, and now that I have met you, it seems that is indeed the case."

"You should know my work experience. In my early years, I worked for ETO. Later, I was recruited by PDC to PES. In recent years, I have been mainly responsible for the construction and design of the research vessel 'Qiusuo'."

The "Qiusuo" is the first research vessel built by the Asian Fleet at Harbin Institute of Technology.

The ship's name is derived from the phrase "The road ahead is long and arduous, but I will persevere in my search," representing humanity's first step in exploring the vast universe.

“Those guys had no idea about the design of this ship at first, but I gave them the best design solution in just one week.”

It's clear that Wei Cheng still harbors some of the pride of a mathematician.

“Yes, that’s why I submitted a secondment request to the PDC. I want you to be in charge of completing the ‘Mirror Project’ in Los Angeles,” Lin Xuan said.

Upon hearing this, Wei Cheng reached for an A4 sheet of paper from the table beside him and began drawing on it while speaking.

“I had heard about that project before. It was a very good design. I thought that the person who designed it must have at least two-thirds of my ability. However, I made some optimizations in some local areas, which may make the project go more smoothly.”

His hands moved without stopping, and each time he put pen to paper, every line he drew was a precise and error-free image.

When Wei Cheng put down his pen, an image of Los Angeles' underground city appeared on the paper.

Lin Xuan picked up the paper and compared it with his design. He then discovered that apart from some of the parts he had changed, the rest were exactly the same!

He took a magnifying glass and magnified the observation to the millimeter level, but it still remained consistent with the design drawing.

Even some incorrect lines on the design drawing, caused by ink cartridges spreading out during printing, resulting in thicker ink marks, were corrected on Wei Cheng's drawing.

"As expected of the guy known as a humanoid computer, his talent in geometry and mathematics is probably hard to find in the human world."

Wei Cheng reached out and placed a few dots on the drawing he had made.

"Well, these few places can actually be optimized. If a lot of people live here in the future, some cables will need to be connected on these two main roads. We need to reserve some expansion modules in advance."

Lin Xuan was shocked.

Goodness, while I'm still figuring out how to build the dungeon, this guy has already considered the city planning after the dungeon is built.

“These are minor matters. The reason I asked you to take charge of this project in Los Angeles is because I need you to incorporate some elements into the construction process.”

As Lin Xuan spoke, she took out the second design and handed it to Wei Cheng.

Compared to the first image, this image is not much different in terms of the main structure, but some key nodes have added components similar to airlocks on spacecraft.

"This picture is only for you, me, and the Trisolarans to know; it must not be told to anyone else."

Lin Xuan was speechless when she said this. The Trisolarans' surveillance was everywhere. Now, when people made oaths, the Trisolarans could hear everything clearly.

After glancing at it a few times, Wei Cheng directly lit the design drawing with a lighter.

"remember."

"remember?"

"Ah."

Wei Cheng's answer was quite calm, as if he were talking about eating and drinking.

Lin Xuan was shocked by the guy's memory speed. He only glanced at it a few times, but he was able to memorize it all. However, considering his ability to draw maps freehand that he had just demonstrated, Lin Xuan didn't question anything.

"Then, for the next few years, you'll have to stay in Los Angeles for a while. The braised noodles and spicy soup there are pretty good. You can try the local snacks when you have time."

Wei Cheng nodded.

"Perfect timing, it's good to change things up. I've been staying in Northeast China for a year, and I'm getting a bit tired of eating things like sweet and sour pork."

After seeing Wei Cheng off, Lin Xuan went to find Liu Chang again.

Liu Chang contacted him in the morning, saying that the reverse engineering of the batch of wheat seeds he had given him had made progress, and asked him to go and take a look.

"The effect is still not as good as the batch you provided, but if it's only for theoretical purposes, it should be enough."

Liu Chang handed Lin Xuan a thick stack of files, which contained experimental records about that batch of seeds.

“I’ve already submitted a copy of the data to PDC, and I’ve also left a backup copy in the Mewtwo world,” Liu Chang said.

Liu Chang was speechless at Lin Xuan's behavior of getting on the train first and then buying the ticket later.

Lin Xuan nodded slightly.

"A theoretical basis is enough, otherwise the PDC will think I conjured up something out of thin air."

"Is not it?"

Lin Xuan didn't want to continue arguing with Liu Chang about this topic, he said.

"After the PDC received the data, did they have any other reaction?"

Liu Chang shook his head.

"No, they have bigger problems to deal with right now."

"What trouble?"

Lin Xuan couldn't think of anything more important than solving the food problem during the Great Depression.

Liu Chang smiled.

"You can check the news online; it's about the Wallfacer Project in Rediaz, which has been secretly restarted by some countries."
