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

Three months later, about four months had passed since Lin Xuan became a Wallfacer.

However, Ding Yi and Wang Miao's space elevator and controlled nuclear fusion technologies have not made much progress.

Lin Xuan wasn't in a hurry. If all else failed, he could just exchange the system for a set and let the two of them figure it out themselves. He was simply too lazy to waste so many shock points.

He is a Wallfacer, not a savior. Humanity must learn to think for itself, instead of relying solely on him.

The best example is Luo Ji in the original work. After becoming the Swordholder, Luo Ji protected the Earth for more than sixty years of the Deterrence Era, but in the end, he was completely destroyed by Cheng Xin.

Lin Xuan felt that this was the result of people relying too much on the great Luo Ji, so he now wanted to make people get used to not relying on him, just like he never relied too much on the system in his mind.

"System, please redeem a cooking robot that can cook for me, thank you."

Lin Xuan placed the cooking robot she had redeemed aside and casually turned on the fruit-cutting robot in front of her that automatically cut fruit.

"Hmm... Using the technology obtained from the system to enjoy life doesn't mean I'm dependent on the system. I'm just a bit lazy. It's not bad to bring smart home technology to this world ahead of time."

Just then, the doorbell rang.

Lin Xuan glanced at the person outside the door through the electronic screen and was immediately stunned.

"Oh, what a rare guest."

The person who arrived was none other than Zhang Beihai, who had disappeared for a long time.

When Lin Xuan met Zhang Beihai before, she left him her home address. She thought that this guy would not come to find her for the next two hundred years, but she did not expect that he would take the initiative to meet her, a Wallfacer.

He opened the door and welcomed Zhang Beihai in. The latter was somewhat shocked when he saw the furnishings and the messy smart home devices in the room.

Shock level from Zhang Beihai +6.

He wasn't shocked by these technologies. After all, smart home technology and big data technology were proposed in the same era, so it wasn't surprising that Lin Xuan was able to implement them.

What truly shocked him was that Lin Xuan actually had the inclination to study these things.

It's important to understand that ever since the existence of the Trisolarans was confirmed, the public has lost much hope for Earth's future.

Therefore, some technologies that are not useful for future wars have been temporarily suspended, in order to save more resources for the upcoming doomsday war.

This naturally includes smart home technology.

Zhang Beihai thought that Lin Xuan, as the fifth Wallfacer, should be under the greatest pressure at this moment, but judging from his current appearance, it was as if he didn't care at all about the apocalyptic war four centuries later.

"Speak, what brings you here? As the director of the political department of the Space Force, you shouldn't have time to wander around here, right?"

Shock level from Zhang Beihai +5.

"You know everything?"

Zhang Beihai was a little surprised.

He was only appointed as the director of the political department of the Space Force by Chang Weisi today. The time between his taking office and his arrival at Lin Xuan's home was less than three hours.

Lin Xuan's information network is incredibly advanced, isn't it?

Little did he know that Lin Xuan was just saying it casually. After all, Zhang Beihai's sudden visit must have been due to some unknown change.

The most likely explanation is that his position as director of the political department has been confirmed.

In the original storyline, in order to deal with the potential rise of escapism in the future space force, General Chang Weisi selected a group of non-commissioned officers with extremely high political awareness to enter the cryogenic chamber as a reserve of talent for the future apocalyptic war.

This plan is called the "Reinforce the Future Plan".

As the proposer of the "Reinforce the Future Plan," Zhang Beihai was naturally a member of the plan. However, in the original storyline, the plan unfortunately coincided with the suicide of the first Wallfacer, Taylor, causing the plan to be shelved for a long time. It wasn't until Ding Yi developed controlled nuclear fusion technology that Zhang Beihai began to implement his plan.

Thinking about it this way, Lin Xuan immediately understood why Zhang Beihai had come to find her.

"Ready to hibernate?"

Taylor's survival means that Zhang Beihai's reinforcement plans may be brought forward.

Before hibernating, Zhang Beihai had one last thing to do: to correct the direction of human scientific research.

Ding Yi has been in charge of the research on controlled nuclear fusion technology. Once the controlled nuclear fusion technology is completed, the construction of a space fleet will definitely be put on the agenda.

As for the development direction of the space fleet, there are currently two options.

On one hand, they were building propellant spaceships, which, to put it bluntly, were just large chemical rockets. The idea of ​​using these to deal with the future Trisolarans was utterly ridiculous.

The other direction is to follow the path of radiation-powered spaceships.

The spaceships manufactured using this technology are more suited to the needs of interstellar warfare, but no one knows whether humanity can achieve this, given that the Sophons have locked down fundamental physics.

Therefore, deciding which path to take becomes a very important decision.

Zhang Beihai definitely favored the latter, since what they needed now was a military force that could truly contend with the Trisolaran fleet, not some space junk that could only fly.

But now the decision-makers are some senior aerospace personnel in high positions, who still prioritize stability.

Therefore, as long as they are alive, they will definitely waste a lot of resources to devote themselves to the construction of propellant rockets.

This would be absolutely fatal to Zhang Beihai's future plans.

Now that the "Reinforce the Future Plan" has been brought forward, the only person who can solve this problem is Lin Xuan, the fifth Wallfacer.

"As expected, nothing escapes your eyes. I want you to think of a way to suggest this to the Planetary Defense Council. If you present it as part of your Wallfacer project, they should take your suggestion seriously."

Hearing Zhang Beihai's request, Lin Xuan sighed helplessly.

“I’m glad you chose to come to me to solve this problem, instead of directly assassinating those old aerospace engineers.”

"Shock level from Zhang Beihai +10!"

Zhang Beihai was completely dumbfounded. He felt as if he had no privacy whatsoever in front of Lin Xuan, as if all his thoughts could be seen by the man in front of him.

Little did he know, Lin Xuan knew the original plot.

In the original storyline, Zhang Beihai, a ruthless man, did exactly that.

In order for the PDC to adopt the proposal for a radiation-powered spacecraft, he assassinated all the old spacefarers and staged it as an accident.

If I can't solve the problem, then I'll solve all the people who raise the problem!
