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

In the afternoon, Lin Xuan and Zhang Xiang took a plane to New York to attend the Wallfacers hearing.

Lin Xuan even asked Luo Ji if he wanted to hitch a ride with her, but Luo Ji refused outright.

"You go ahead, I won't go. It doesn't really matter whether I attend this kind of meeting or not. After all, if I had to say something, all I could do is tell them which countries I've traveled to in the past two years. I'm sure the PDC wouldn't like to hear that."

Left with no other choice, Lin Xuan had to go by herself.

Zhang Xiang appeared very comfortable on the plane.

Since Luo Ji arrived at the Red Coast Third Base, he has been talking with Luo Ji about the events that have occurred in the past two years.

Luo Ji was a university professor, and having traveled to so many places, his knowledge far surpassed Zhang Xiang's.

After a few casual words of flattery, Zhang Xiang began to yearn for Luo Ji's life.

"I'm so envious of you, Teacher Luo. I wish I were a Wallfacer so I could travel around with you like this."

Luo Ji gave a helpless smile but did not answer the question.

In fact, he was under a lot of pressure. Since becoming a Wallfacer two years ago, Luo Ji had never stopped thinking.

He was pondering a question: Why did he become a Wallfacer?

This is crucial; only after knowing this can Luo Ji proceed with the next step of reasoning.

In the past, Luo Ji did not take the identity of a Wallfacer seriously. He only wanted to enjoy the rights that came with being a Wallfacer, but he did not want to bear the responsibilities of being a Wallfacer.

However, since the birth of his daughter a few months ago, Luo Ji has developed some different feelings.

He suddenly began to feel a sense of attachment to this world.

The thought that this wonderful world would be occupied by a group of aliens four hundred years from now filled Luo Ji with an indescribable pessimism.

Humans are such strange creatures; they only realize the value of something when they are about to lose it.

Luo Ji didn't completely want to give up his responsibilities as a Wallfacer; rather, he felt helpless about it.

He didn't know what he could do for this collapsing world.

He thought about it for a long time, but still had no clue.

Even someone as capable as Taylor is now surrendering along with him.

Diaz was also better than him, but his daily work, besides manufacturing a larger hydrogen bomb, consisted of challenging the PDC at the conference table.

Hines also had his own plans, but Luo Ji felt that his plans were almost impossible to realize.

The only thing that gave Luo Ji a glimmer of hope was Lin Xuan.

Whether advocating for the Super Dream Project or implementing the space elevator and controlled nuclear fusion projects, Lin Xuan has always been at the forefront of humanity's struggle.

He once thought that Lin Xuan would be a useless Wallfacer like himself, but Luo Ji realized that he was wrong; Lin Xuan was far better than him.

They were even stronger than all of the Wallfacers combined.

……

The plane landed smoothly in New York City, and Lin Xuan and Zhang Xiang walked into the venue.

Only three Wallfacers attended this meeting.

Lin Xuan, Hines, and Reydiaz.

Lin Xuan glanced at the seats inside and outside the hall and saw a few familiar faces.

Chang Weisi and Fitzroy, two high-ranking military and political officials, also attended the meeting.

In the original storyline, General Fitzroy confirmed the existence of the Trisolaran fleet's invasion using the Hubble Space Telescope 2.

Because he was in charge of managing the NMD system, Lin Xuan rarely saw him, only occasionally meeting him at PDC meetings.

Another person who attended the meeting was Thomas Wade, the director of the PIA intelligence department.

Since Cheng Xin went into hibernation due to illness, Wade has been following up on the Ladder Project.

The probe is flying faster than they imagined, and barring any unforeseen circumstances, it should meet the Trisolaran fleet in about a hundred years.

As the meeting began, Galnin reluctantly walked onto the podium.

This year he is the rotating chairman, but he is not happy.

Because of Lin Xuan's presence, Galning was on tenterhooks for the past two or three months since becoming the rotating chairman of PDC, fearing that Lin Xuan would give him a tough challenge right away.

He just wants to end this meeting as soon as possible and then wait until next year, when Sai will be the rotating chairman of the PDC again.

Ryoko Kamisato, during her tenure as chairman, quipped that Lin Xuan single-handedly turned the position of PDC chairman into a time bomb, making it so that no one dared to take it, and everyone was passing it around, afraid that the bomb would explode in their hands.

Similar to previous Wallfacer hearings, after a simple preliminary process, it was time for the two Wallfacers to explain their work progress.

This time it was Lin Xuan's turn to give her report, and everyone in the room held their breath.

The memory of Lin Xuan's surprising statement and her casually producing a controlled nuclear fusion algorithm is still fresh in my mind.

They've learned their lesson now; before Lin Xuan speaks, everyone keeps quiet and doesn't ask her any questions.

But this time, Lin Xuan's work report seemed rather conventional.

It simply stated that the database for Project Super Dream had been completed and that the three space elevators would be officially put into use in the 7th year of the Crisis Era.

"good, very good!"

Galnin couldn't help but lead the applause.

He wasn't applauding Lin Xuan's work progress, but rather delighted that Lin Xuan was finally able to perform normally this time.

Meanwhile, everyone in the venue who had been on tenterhooks breathed a sigh of relief, and some even wiped the cold sweat from their foreheads.

Lin Xuan has had such a huge impact on these people over the past two years that they now have a psychological shadow over her, always feeling that she might do something crazy at any moment.

The next Wallfacer to report was Hines.

Many people are optimistic about his plan and are quite interested in it, since improving human intelligence has always been one of the important topics of human exploration.

So when Hines said that current hardware technology could not meet the requirements of his plan, the PDC unanimously approved his hibernation application.

The last one is Radiáz.

Everyone is aware of his recent actions, and many people have long harbored resentment towards him as the second Wallfacer.

Radiaz stood up, ignoring the stares directed at him, and spoke.

"My plan requires technical support from PDC."

"The construction of a model of a larger-yield stellar-class hydrogen bomb is simply impossible with current computer capabilities."

"Even if we were to complete just one percent of the model of the entire project, it would take the computer a full twenty years."

"Therefore, I need PDC's permission to borrow Lin Xuan's Super Dream Database to complete the calculations for the entire stellar-class hydrogen bomb model."

Upon hearing this, everyone turned to look at Lin Xuan.

Everyone had heard of Lin Xuan's Mega Dream Database; it was said to be able to enhance the computing power of computers by using the human brain as a computing unit.

This thing is like a biological computer, but the one Lin Xuan created is clearly more advanced, already involving things at the level of consciousness.

"This is impossible."

Lin Xuan directly rejected Radiaz's proposal.

“Mr. Radiaz, I don’t know if you were aware of the Dream Database I created before making this request. It has only completed the first stage of data construction and is far from meeting the computational requirements you are asking for.”

Rediaz nodded slightly.

“I know, I’ve considered that, which is why I hope PDC will agree to my request. As far as I know, the first phase of your database project is complete. The reason you can’t reach the computing power I’m asking for is not because the database can’t handle it, but because you’re worried that too much computing power will cause irreversible damage to the computing unit.”

Radiaz is right. The database is basically complete. If we want to increase computing power, we can connect more human brains. This will increase the computing power of this machine quite quickly.

However, since the second phase of the Super Dream project has not yet begun and the algorithm has not been optimized, if the computer is forced to perform such a high-load task, the computing unit will crash.

If it were just a regular computer, you could simply replace the computing unit if it crashed. But the computing unit of Lin Xuan's database was a living, breathing person!

To put it bluntly, what Radiaz is doing is using human lives to increase computing speed, because once the brain is overloaded with this kind of computation for a long time, there is only one outcome: brain death.

"You're committing murder!"

Soon, the representative of the United States spoke first.

The representative of the British Empire was more rational; he asked Diaz for his opinion.

How many people will die?

"According to preliminary estimates, based on the average human brain's workload, completing this project would result in approximately 14,000 deaths."

"You're insane! You're going to kill over ten thousand people to build your model? You're a complete madman!"

The American representative could no longer hold back and directly cursed.

However, Radiaz was completely unconcerned about the insults he received from the crowd.

"Gentlemen, necessary sacrifices are worthwhile. If the deaths of ten thousand people can accelerate the development of my stellar-class hydrogen bomb model, then I think it is worth it."

"I disagree."

It was Lin Xuan who spoke.

No one expected that Lin Xuan would preemptively reject Diaz's request before PDC could.

“I designed the Super Dream Project. It enjoys the same rights and status as other Wallfacer projects. I strongly oppose your plan to turn that machine into a tool for slaughtering and harvesting human brain computing power.”

"Besides, I think these sacrifices are meaningless. Your plan has already wasted a lot of human resources, and now you want to waste more than 10,000 lives?"

The first sentence was generally agreed upon by everyone, but Lin Xuan's second sentence surprised everyone present.

Why does this sound so familiar?

Upon hearing this, Rediaz shook his head slightly.

"You say my plan is a waste of resources, how can you prove it?"

A barely perceptible smile suddenly appeared on Lin Xuan's face; it seemed he had been waiting for Radiáz to say those words.

"Everyone saw it, he asked me to prove it himself, I didn't force him!"

At this moment, everyone present felt a chill run down their spines. They finally remembered why that sentence sounded so familiar. Lin Xuan had said the same thing when she broke through Taylor's barrier.

"Could it be..."

Everyone felt their breathing quicken, and a very bad premonition rose in their hearts.

Lin Xuan slowly opened her mouth, speaking each word slowly and deliberately.

"Wallfacer Rey Diaz, I am your wall breaker!"
