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

Crisis Era 21, 2028 AD.

Eighteen years have passed since the Wallfacer Project began.

The potential dangers posed by "immortals" are gradually becoming apparent in human society.

Death was once the only fair thing between the rich and the poor, but now, this fairness has been completely shattered with the advent of cell division fluid.

A lifespan of three hundred years is enough for a rich person to accumulate wealth exceeding that of a country, and class solidification has almost reached its peak.

More and more chaebol families are rising up, fighting and scheming against each other.

This made the already impoverished lives of the lower classes even worse.

In a short time, the public's condemnation of PDC grew stronger and stronger. If it weren't for the cloning technology provided by Lin Xuan, the chaos created by the crowd would have already overturned the entire PDC building.

Previously, when people learned that Lin Xuan possessed a life-extending drug but did not disclose the technology to the PDC, many accused Lin Xuan of selfishness. However, due to the construction of the space elevator and the mirror project at that time, these negative voices about Lin Xuan hardly caused any waves.

But now, Lin Xuan's wise move has once again raised people's expectations for this Wallfacer.

Some people even hope that Lin Xuan will become one of the rotating chairpersons of PDC to oversee the behavior of the entire PDC.

Ultimately, left with no other option, the PDC had to issue three decrees.

First, the immortals will pay 30 percent of their total annual income in taxes each year, and an additional 1 percent will be collected every ten years.

Second, starting from Crisis Era 21, those who become immortals are prohibited from holding any military or political positions or participating in any political activities.

This resolution nearly cost Chang Weisi and a number of other senior officers their jobs. In the end, it was only through a joint vote by Zhang Huaimin and a group of high-ranking Chinese officials that Chang Weisi was able to retain his position in the Asian Fleet.

As for the third and most ruthless one, all immortals must participate in the Future Reinforcement Plan and fight for the future.

The enactment of these three laws directly resulted in the immortals, who were originally above tens of thousands, becoming exploited money-making machines. All the wealth they acquired, in a legal sense, belonged to the PDC.

This is actually a result of a time lag.

Lin Xuan had been stuck on the technology of RX cell division fluid for a long time before PDC finally managed to reverse engineer it. At this time, the harbingers of a major downturn were just beginning, and the problems of human society were being amplified at an accelerated pace.

There seems to be no problem, but the problem lies in this time difference.

Just as the first generation of rotating presidents of the PDC retired, immortals appeared. However, all the previous generation of rotating presidents of the PDC gave up the possibility of becoming immortals, because it was necessary to ensure the succession of the PDC rotating president and the representatives of various countries. After all, the PDC has now become the largest power center in all of humanity. Once the representatives of the PDC can all live to be over three hundred years old, the PDC will become a feudal autocratic power group.

This allowed Zhang Huaimin and his generation of rotating chairpersons to continue this tradition.

This tradition, in theory, would essentially cease to exist after three iterations. After all, those in power crave immortality. Perhaps after Zhang Huaimin steps down, the next rotating chairman will begin using this cell division agent.

Subsequently, the world order deteriorated rapidly. The social conflicts caused by the immortals erupted within three years of Zhang Huaimin's generation taking office as the rotating chairman. The next generation of rotating chairmen did not even have time to be elected before their possibility of becoming immortals was completely nipped in the bud.

After all, the top executives of PDC are just a group of ordinary people. After seeing the harm brought by immortals, they are even less likely to choose the path of immortality.

However, that's how people are; once they discover they can't live forever, they begin to relentlessly suppress the group of immortals.

The international community began to tighten controls on cell division drugs, prohibiting their use by anyone except the Space Force. Those who had become immortal were also having a very difficult time, becoming a chosen worker who had to work endlessly for the PDC for the rest of their lives.

Many immortals even chose to end their lives by committing suicide, which gradually reduced the hostility of human society towards immortals.

In less than six months, the term "immortal" went from being envied to being despised.

The immortals also ended up being ridiculed, just like the hibernators of yesteryear.

When people look back on this history, they can't help but marvel at Lin Xuan's great wisdom. He may have foreseen that human society would become like this, and people had misunderstood his actions before.

This time, a barrage of shock points flooded Lin Xuan's mind once again.

Lin Xuan was completely dumbfounded. She hadn't done anything, so why were there so many shock points?

Although the global economic system has collapsed beyond recognition, people's investment in education remains the same as before.

After all, the future depends on the next generation to continue developing science to deal with the Trisolarans, and no country has ever ruined itself by pursuing education, so this is a long-term investment.

"By the way, Congmin, why are you so free today? You even have the mind to read. Have you finished your homework?"

Lin Xuan suddenly looked at Luo Congmin, who was reading a book next to her.

"Um, I've already finished my middle school entrance exam, so I don't have any homework."

Lin Xuan was taken aback, and then realized that this girl was almost 16 years old this year and would be going to high school at the end of the year.

"Ah... uh, is that so?"

"Otherwise what? You're my brother, don't you ever care where I go to school?" Luo Congmin rolled her eyes at Lin Xuan.

Despite the diligent instruction of Wang Miao and Ding Yi, Luo Congmin's performance in mathematics and physics remained consistently poor, even absurdly so.

However, she possesses extraordinary talent in the humanities and social sciences.

In her first year of junior high, she began submitting articles to various magazines and publishing some collections of prose poems. In her second year of junior high, while her peers were still playing video games, this girl had already begun studying Leo Tolstoy's "Resurrection".

So much so that the girl had a whole warehouse full of books.

Lin Xuan previously suggested that she could find someone who had read these books to extract the knowledge and then transmit it to Luo Congmin, which would save a lot of time, but Luo Congmin refused.

She insisted on reading herself, and even now that e-books are so common, she still prefers to read physical books. She says that every time she reads these books, her thoughts can transcend time and space to connect with the authors.

The humanities and social sciences are different from the natural sciences. The truths of the natural sciences are fixed; they are there, waiting for you to discover them. The truths of the humanities and social sciences are obvious, but everyone needs to use their own thinking to ponder and understand them.

But Lin Xuan wasn't interested in these books. Every time he read them, the dense text made him feel drowsy, and he would lose interest after reading just two pages.

"By the way, don't you have any thinner books? These books are all too thick; I can't possibly finish reading them."

"Thinner books? Yes, they're on the bottom shelf."

Lin Xuan bent down and indeed found a book that was noticeably thinner than the surrounding books.

"The History of the United States?"

Lin Xuan: ? ? ?
