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

In the fourth year of the Crisis Era, approximately eight months have passed since the Wallfacer Project was implemented.

"Happy New Year!"

Inside the Red Coast Third Base, Lin Xuan, Ding Yi, Wang Miao, and a large group of staff members were celebrating the arrival of New Year's Day.

This winter was exceptionally cold, and the snow piled up thickly in front of the Red Coast Base. Zhang Xiang volunteered to drive a bulldozer and spent a whole day clearing it before finally managing to clear the road.

"Hey, do you know that next year is the end of the world as predicted by the Mayan civilization?"

As Zhang Xiang spoke, he picked up a piece of tripe with his chopsticks and put it into the bubbling hot pot in front of him.

His words were originally intended to lighten the mood, but in the context of the Trisolaran invasion, they immediately silenced everyone in the room.

"Zhang Xiang, you're really something. You silenced a group of people with just one sentence. Your AOE effect is much stronger than the electromagnetic weapons I've been researching recently. I should have put your mouth on the table."

Wang Miao laughed and joked, breaking the awkward atmosphere.

"Uh, I was just saying."

Knowing he had spoken out of turn, Zhang Xiang said nothing more and turned to look at Lin Xuan, who was deep in thought.

"Brother Lin, what are you thinking about?"

After a year of getting along, the people in the Red Coast Third Base had become as close as family. Occasionally, people from the PDC would come over to check on the progress of the [Super Dream Project] and borrow the super database to store some useful information.

Lin Xuan's thoughts were interrupted by Zhang Xiang, and she finally realized what was happening.

"Huh? Oh... nothing, I was just thinking, it's 2011 already, shouldn't the nuclear power plant in that island nation have leaked by now?"

Everyone:? ? ?

What words?

Although everyone knows that there are some grudges between China and the island nation, isn't it inhumane to curse them for a nuclear power plant leak?

Lin Xuan was too lazy to explain. If the fourth year of the Crisis Era corresponded to the real-world year 2011, then the earthquake in the island nation would likely arrive as scheduled.

"It's a pity that Zhang Beihai has already entered hibernation. Otherwise, we could have invited him to the New Year celebrations this year. That way, it would be more lively with more people."

Zhang Beihai entered hibernation a month ago, at the end of the third year of the Crisis Era. Zhang Xiang told Lin Xuan about this, and his "Reinforce the Future Plan" was finally approved by the PDC.

Lin Xuan had given instructions on this matter to some extent, so the overall approval process went quite smoothly.

In fact, after being injected with the cell division agent, he could have completely avoided hibernation, since his lifespan was already quite long, but Zhang Beihai insisted on hibernating.

The reason is probably only known to Lin Xuan.

He actually admired this guy quite a bit; at this moment, he had the courage to decide on his own escape plan and even foresaw the possibility that he would spend the rest of his life in endless space.

To ensure the success of the plan, Zhang Beihai resolutely abandoned his wife, children, and elderly parents. Although the PDC would take care of them, Zhang Beihai was still worried and eventually asked Zhang Xiang to take his children to the Red Coast Third Base.

“By the way, Brother Lin, Dr. Luo Ji said that he and Zhuang Yan are going to come back to China after the New Year, apparently to register their child’s household registration. PDC asked me to go and meet them.” Zhang Xiang suddenly said.

"You have a child?"

Lin Xuan was somewhat surprised to hear this news.

He originally thought that the two of them would not have children for at least two years, since in the original plot, Zhuang Yan seemed to have gone into hibernation shortly after the child was born.

At that time, Taylor had just committed suicide. It should have been in the 8th year of the Crisis Era, which is about 4 years ago now.

"It seems the plot has taken a significant turn. If Taylor doesn't die, Luo Ji can't possibly remain unable to deduce the Dark Forest Theory forever, right?"

Lin Xuan felt a pang of regret. If that were really the case, she might as well not have saved Taylor.

If Taylor knew about Lin Xuan's idea, she would probably go for a 6.

"Alright, let them come to my place while they're here. We haven't seen Luo Ji in a long time, and I happen to need to see him too."

Zhang Xiang nodded slightly, then shook his head.

"No, Brother Lin, that's not what I meant. What I meant was, we're both Wallfacers, but Luo Ji already has a child, while you, Brother Lin, don't even have a partner?"

Lin Xuan was silent for two seconds before meeting Zhang Xiang's gaze.

"Can I ask the PDC to put you into hibernation and bring Shi Qiang back?"

Upon hearing this, Zhang Xiang immediately waved his hand.

"No way, Brother Lin, I was just asking. Besides, even if you wake up Captain Shi, he'll ask the same question. I heard him say that when you first became a Wallfacer, you flirted with a girl named Cheng Xin in front of the PDC building, but you failed. If you really want to find a girlfriend, I can teach you a few tricks."

Lin Xuan: ? ? ?

"Wang Miao, call the hibernation management office and tell them to wake Shi Qiang up. I'll kill him right now!"

Just as the group was laughing and chatting, Lin Xuan's phone rang.

Lin Xuan picked up the phone and saw that the caller ID showed it was Weide.

"Lin Xuan, I've taken care of the matter you asked me to investigate last time."

When she answered the phone, Wade's calm, still voice came from the other end. From his voice alone, Lin Xuan could not sense any emotional fluctuation in him.

"So fast?"

Lin Xuan thought it would take Wade a long time, but it turned out that only a few months had passed and there was already progress.

"Yes, the good news is that the information you gave me last time was indeed reliable. Our experiments have shown that the influence of sophons on some research areas has indeed weakened. The bad news is that these experiments have made almost no substantial progress in scientific development."

As he spoke, Wade began to read aloud.

“2001年5月4日，2003年12月1日，2009年1月5日……”

Lin Xuan took out a piece of paper and quickly wrote down all the dates on it.

Wade didn't explain the meaning of these dates, because if he did, Zhizi would also know, and the intelligence gathering would be pointless.

But he believed that with Lin Xuan's intelligence, she should be able to understand the meaning of this coded message.

Sure enough, after hanging up the phone, Lin Xuan stared at the dates for a moment before understanding the hidden message in Wade's words.

“张翔，去帮我调取一份2001年5月4日的福克斯新闻内容，以及2003年12月1日BBC新闻报道，然后是2009年1月5日的华夏新闻联播……”

Wade gave Lin Xuan a total of 7 sets of time, and the number 7 corresponds exactly to the PDC's G7.

The chronological order should correspond to the dates when the seven countries joined the PDC. Therefore, matching these dates with the important news that happened in their respective countries at that time is the message that Wade wanted to convey to himself.

Soon, Zhang Xiang found the news of the day for the seven countries according to Lin Xuan's needs.

On May 4, 2001, the Pentagon was attacked by Chinese hackers, and all the pages of American websites were covered with the Chinese national flag.

On December 1, 2003, an influenza virus outbreak occurred in the British Empire.

On January 5, 2009, China began to take measures to deal with the rampant spread of swine flu.

On July 7, 2010, a large number of machines in France malfunctioned, suspected to be due to a Trojan virus attack.

……

By connecting all the events that occurred in the seven countries at different points in time, Lin Xuan quickly discovered their commonalities.

They all involve viruses or the spread of viruses.

However, it's somewhat puzzling whether "Vade" refers to a Trojan virus or a biological virus.

After all, among the events at these seven points in time, there were both Trojan virus attacks and biological viruses, which left Lin Xuan somewhat confused, unsure of what Wade was trying to express.

Just then, Wang Miao, who had finished eating, came over and looked at the information Lin Xuan was organizing on the paper.

"Um... Lin Xuan, this seems to be talking about the development direction of our Super Dream server."

Lin Xuan was taken aback.

"Huh? How come I didn't notice?"

He genuinely couldn't see any connection between these news reports and blockchain technology. If Wang Miao hadn't reminded him, he would have been thinking about the spread of the virus.

Wang Miao pointed to the information Lin Xuan had listed and let out a burp.

"Look, the first news item says that Chinese hackers attacked the Pentagon in the United States, and the second news item says that a virus has appeared in the British Empire. From these two pieces of information, we can roughly determine that what Wade is trying to say is related to some kind of computer virus."

"As for the third point, it seems to be talking about biological viruses, but it is actually talking about ways to eliminate viruses, because the swine flu outbreak in China back then took a long time to be eradicated, and each virus has independent transmissibility."

"If Wade was simply expressing his opinion on the virus, he could have easily chosen a different news story, such as the Philippines-China conflict in 03."

Lin Xuan nodded slightly upon hearing this; Wang Miao's analysis made a lot of sense.

"As for the fourth point, I know about the French incident. At that time, nearly 50% of the machines were paralyzed, and the crisis was only resolved by replacing them all."

……

Lin Xuan quickly reorganized Wang Miao's analysis in her mind.

A computer virus, each virus is an independent entity, can spread and replicate in its surroundings, and is extremely difficult to eliminate, crippling more than 50% of systems...

Lin Xuan's eyes lit up instantly.

"I get it, Wade is talking about blockchain technology!" he thought to himself.

Blockchain technology is a technology that was developed by humankind only a few years later.

Simply put, blockchain technology functions as a trust protocol.

Unlike other protocols that have a central point as the overall control end, the biggest feature of blockchain technology is decentralization, or in other words, everyone is the center.

This ensures the absolute security of the technology, because without a central control point, it is virtually impossible to attack its central server.

Just as attacking someone's brain or heart will kill them, blockchain technology is like a Mahayana cultivator in a fantasy novel, capable of achieving rebirth from a drop of blood.

Conversely, his resolutions are difficult to eliminate or tamper with from a single node unless you can compromise more than 50% of the nodes; otherwise, tampering with his data is meaningless.

In this way, it seems that neither attacking the center nor attacking the nodes will work. In fact, if you want to perform some dangerous operations through the nodes, the technology also has the ability to trace back to the source.

In this light, blockchain technology almost perfectly aligns with all the information represented by the seven news items provided by Wade.

But Lin Xuan knew that, given Wade's personality, he would never simply tell her these things.

He must be hiding a deeper message.

Lin Xuan tossed the paper aside. Zhi Zi had been watching him constantly, so he had to complete the analysis on his own.

From a timeline perspective, blockchain technology had not yet been developed in this era, so what Wade wanted to express was likely related to his "Super Dream Project".

Wang Miao confirmed this as well, saying that what Wade was referring to was likely related to the optimization of his own servers.

In that instant, Lin Xuan thought of a possibility.

"understood!"

A smile appeared on Lin Xuan's face.

"As expected of you, Wade, you actually came up with such a brilliant idea."

The fact that Wade specifically told Lin Xuan about blockchain technology is likely because he wanted to convey a certain meaning.

Do not create databases in places that are visible to the public.

If possible, all data should be stored together in the brains of all humans!

madman!

This guy is absolutely insane!

Lin Xuan felt somewhat shocked.

He created the "Super Dream Project," intending to use all human brains as computing units to build a space elevator for himself, but Wade was even more insane.

He wants to put even the databases created by supercomputers directly into the human brain.

If the consequences of doing so can be applied to all of humanity, then humanity will achieve a brainwave communication method similar to that of the Trisolarans!
