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

Lin Xuan thought for a long time before she remembered who this guy was.

The genius mathematician that Shen Yufei "kept".

Shen Yufei is the representative of the ETO's salvation faction in the first book of The Three-Body Problem. She valued Wei Cheng's mathematical achievements and asked him to help solve the Three-Body Problem. She even married him in name only.

Later, Shen Yufei died, and Wei Cheng was taken away. The story never mentioned where he went. If Wang Miao hadn't brought it up, Lin Xuan would have thought he was dead.

"He now works at PES, mainly responsible for ballistic missile calculations for some weapons and the deployment of future Earth defense orbits. PDC noticed his mathematical talent very early on, so they recruited him ahead of time."

"This guy has a nickname now, Humanoid Computer. You know the Reach space station, right? He was in charge of designing it. My god, Lin Xuan, you don't know, that space station is simply a work of art. Wei Cheng refined its orbital deviation to the thickness of a finger. The difficulty is comparable to standing a marble slab on a needle."

Lin Xuan's focus, however, was on something else entirely.

What is PES?

"The Planetary Defense Council's Space Engineering Division (PES), like the Planetary Defense Agency (PIA), is an independent department of the Planetary Defense Council (PDC). Its main tasks are related to Earth orbit and the construction of spacecraft."

Lin Xuan nodded slightly.

This was the first time he had ever heard of PES; it wasn't in the original storyline.

However, upon reflection, this makes sense. It's impossible for the PDC to have only one independent department, PIA Strategic Intelligence; it's just that it wasn't mentioned in the original storyline.

"The spacecraft design, like the space elevator, involves three projects being carried out simultaneously. Would you like to take a look?"

Lin Xuan shook her head.

"Not interested. No matter how it's designed, it's just space fireworks anyway."

Lin Xuan spoke very softly, and Wang Miao didn't hear her clearly.

"what?"

"nothing."

Lin Xuan waved her hand.

"In that case, you'll have to fly to New York. Should I have Zhang Xiang take you there?"

“No need, the engineering department is located within China,” Wang Miao said.

"You don't know this yet, do you? To save time, the PDC has consolidated the fleet design work from more than seventy countries into three: the Asian Fleet, the European Fleet, and the North American Fleet."

Lin Xuan was taken aback.

"Good heavens, isn't this the prototype of the future solar system fleet?"

In the original storyline, after the Great Depression ended, the PDC evolved from the Planetary Defense Council into the Solar System Fleet Joint Conference, becoming independent of all nations on Earth and establishing its own sphere of influence in space.

"I am mainly responsible for the engineering and manufacturing of the Asian Fleet. The construction base for the first warship of the Asian Fleet is in Northeast China, with PES providing technical guidance and Harbin Institute of Technology responsible for the specific implementation. So there is no need to see me off. PES has already booked my flight to Heilongjiang Province."

"I see."

That makes sense, after all, Harbin Institute of Technology is the only university in the world with nuclear strike capability, and its heavy industry is relatively developed, so it's not surprising that the first warship base was built there.

"Looks like I need to speed things up too."

……

Three days later, inside the Three-Body game.

Qin Shi Huang stood on a high platform, looking down.

"What kind of work are you doing? All the Trisolaran warriors are nothing but a bunch of shameless, disloyal cowards!"

From the audience, Planck was the first to voice his opposition.

"Ying Zheng, I cannot agree with your point of view. Those ETO warriors who sacrificed their lives for the Lord should not be insulted like this."

"Bullshit! They're nothing but cowards! Traitors! Good-for-nothings!"

Enraged, Qin Shi Huang swung his long sword, slamming it onto the ground with a loud thud.

"You have absolutely no honor!"

“ETO has been established for so many years, and all you’ve learned is to fish in troubled waters. All you’ve ever done is obstruct my actions and hold me back in various ways. I should be like Lin Xuan and donate all of you useless people to organ donation!”

His finger trembled as he pointed at the group of ETO core members below the stage.

"You call yourselves highly educated intellectuals? Look at what you've done all these years!"

"A bunch of idiots. I put you in charge of sowing discord, and look what you've done! For the past few years, you've been using the name of Sophon Information to sow discord between the Space Force and the PDC. And what's the result? Being smeared by you has become an honor, even a symbol of loyalty."

Everyone was silent.

"Thanks to you guys, Chang Weisi is almost promoted from the commander of the Space Force to the head of the Asian Fleet, and Wang Miao's space elevator is almost up to the point of being on God's face. Is this what you people have accomplished in just a few years?"

“This has nothing to do with us; it’s all because of Lin Xuan,” Newton said.

“His control over the overall situation is too great, and the technology he possesses far surpasses current Earth technology. We need to ask the Lord to transmit higher-level technology to us so that we may have a chance to defeat Lin Xuan.”

“That’s impossible,” Ying Zheng said.

"The Lord has two commands for us: first, to kill Luo Ji, the Wallfacer, without attracting the attention of others; second, to try to win over Lin Xuan."

“I don’t understand,” Newton said.

“This task is too difficult, especially the first one. We need to know why we can’t attract other people’s attention,” Planck continued.

"It cannot be spoken of. Evans may know, but he is dead now."

"The second question is about Rediaz," Mozi said.

"Zhi Zi observed that Lin Xuan did not execute Rediaz as required by the PDC. Could this person pose a potential threat to the upcoming plans?"

"no."

"The Lord doesn't care about his plans, but as Lin Xuan said, Diaz's actions will bring forward the environmental crisis for humanity. Humanity may very well restart civilization in this despair and have the opportunity for a second Renaissance. At that time, humanity will complete a technological leap in a short period of time, and there is a possibility of a large-scale outbreak of escapism, which is something the Lord does not want to see."

"understood."

After a long silence, Freud finally spoke.

"We need to try hacking into the Super Dream database. Perhaps we can cooperate with Lin Xuan. Otherwise, this technology will cause us a lot of trouble."

"Would the Lord agree?"

"He will agree. According to the Lord's will, Lin Xuan's threat lies in himself, not in his creation. The Lord's will is to take the gentlest approach toward Lin Xuan. The Lord's speculation about him is not clear and needs to be constantly revised."

"Aristotle!"

Qin Shi Huang suddenly pointed his long sword at Keiko Yamasugi below.

"You need to speed things up and complete the Wall-Breaking task against the Wall Breaker Hines before Lin Xuan does."

Keiko Yamasugi nodded slightly.

"I'm still a little short. I need to apply for a period of hibernation."

"can."

"Hiens' plan requires a analytical camera based on CT scan and MRI technology. Lin Xuan is currently in charge of this. When he is able to implement this technology, please wake me up."
