Kante's arrival did not change the trajectory of Pang Xuelin's life in a short period of time.

Although the countries of the wall facing plan have reached a consensus, there is still a lot to be argued about the authority and selection of those who face the wall.

The four people who face the wall are the former U.S. Secretary of Defense Frederick Taylor, the former president of Venezuela, Manuel Rediaz who performed well in the process of resisting American aggression, and the former president of the European Union, Bill Hines, who is not only a politician, but also an outstanding scientist, who has been nominated for the Nobel Prize in Medicine or Physiology and the Nobel Prize in Physics for discovering that the brain's thinking and memory activities are carried out at the quantum level, and the last one who faces the wall is prompted by Ye Wenjie, Preparing to create a cosmic sociology.

Of these four people, Taylor represents the interests of the United States, Manuel Rediaz represents the interests of Russia and third world countries, Bill Hines represents the interests of Europe, and Luo Ji undoubtedly represents the interests of China.

Pang Xuelin didn't know if Luo Ji had entered the sight of the Planetary Defense Council because of the ETO assassination at this time, if not, it was better to say, if there were, then there were two candidates from China.

As the proposer of the wall-facing project, as well as the top mathematician in the world, coupled with his former ETO membership, he is convincing enough to become a wall-facer.

Not to mention Luo Ji, the factor of the Trisolarans ordering ETO to assassinate Luo Ji alone is enough to make Luo Ji enter the ranks of those who face the wall.

Therefore, whether China can get the quota of the two facers depends on the government's game within the PDC (Planetary Defense Council).

However, one thing Pang Xuelin can be sure of is that his current treatment has not shown signs of decreasing, and even after Kante came over, Pang Xuelin's treatment in both security and all aspects has even been further improved.

Originally, Zhuang Yan knew that Pang Xuelin was alone in this world, and he still thought of inviting Pang Xuelin to her house to spend Chinese New Year's Eve together.

As a result, it failed the security audit.

In the end, Pang Xuelin discussed with Li Yao and decided to have a Chinese New Year's Eve dinner together at Xishan Villa on Chinese New Year's Eve.

So, on Chinese New Year's Eve, Li Yao and Wang Miao brought their son over, Zhuang Yan and her mother were also invited over, plus the staff in the villa and Kante, who had almost become Pang Xuelin's personal assistant, everyone gathered together to make dumplings and eat Chinese New Year's Eve dinner to watch the Spring Festival Gala, and had a lively Spring Festival.

After the Spring Festival, Pang Xuelin entered a busy state again.

Except for the occasional pass through Kanter, where he made some specific comments and suggestions on the "Wall-Facer Act", he spent most of the rest of his time immersed in papers on macrophysics.

The biggest difference between this world in the field of basic science and the real world is the discovery of macroatoms.

The so-called macroatom refers to the atom that is visible on the macroscopic scale.

This is the black technology shown in Liu Cixin's other "Ball Lightning", but the worlds of "Ball Lightning" and "Three-Body Problem" are on the same side, so the existence of macro atomic technology has also been mentioned in the Three-Body Problem.

The nucleus of a macroatom exists in the form of a two-dimensional string, has no entity, and can only be observed by refracting visible light, while the macroelectron exists in the form of a "cavitation", which is visible to the naked eye, and is excited by lightning and other lightning to become a ball lightning.

In the absence of observers, the macro electrons excited by energy are in a quantum state, and everything can only be described by probability, and the probability of being excited is very small.

Humans destroyed by macroelectrons (ball lightning) do not die, but instead live in another world in a form similar to a "ghost", with only a small chance of appearing in this world. (Because it collapses when it is observed, thus explaining the existence of the soul)

To this end, Pang Xuelin specially found the discoverer of macroatoms, Nobel Prize winner in physics Ding Yi, and wanted to ask him if he had any way to shield the monitoring of Zhizi from the aspect of macroatoms.

In the evening, Pang Xuelin, Kante and Ding Yi sat on the terrace of Xishan Villa, chatting while drinking tea.

"Block Jiko's surveillance?"

When Pang Xuelin came up with the idea, Ding Yi took his trademark large pipe in his mouth and fell into deep thought.

After a long time, Ding Yi shook his head and said: "Actually, up to now, our understanding of macroatoms is still quite rudimentary, and after Zhizi appeared, we also interfered with the related experiments of macroatoms, so I didn't think of any suitable way to shield Zhizi for the time being." ”

Pang Xuelin nodded, not surprised by this answer.

, Friedric Taylor, the wall-facing man, wants to use a ball lightning weapon against the Trisolarans, but the final answer is "The Lord doesn't care." ”

This can also indirectly show that the research of macroatoms by the Trisolarans may be far beyond human imagination.

Even in the third part of the three-body problem, "Death and Immortality", there is a saying that macroelectrons (ball lightning) are formed after the low-dimensional expansion of microelectronics.

According to string theory, the universe is made up of 11 dimensions of space-time, of which 10 dimensions are the spatial dimension and one dimension is the time dimension.

The reason why we see the universe is three-dimensional is because the remaining seven dimensions are curled up in microscopic particles.

In the early days of the three-body world, the universe took on a ten-dimensional form.

In the ten-dimensional universe, the speed of light is infinite, and light can travel from one end of the universe to the other in an instant.

But later, because of the war between civilizations, the macroscopic dimension of the universe continued to collapse through dimensional reduction attacks, and finally formed the three-dimensional universe visible to the naked eye of human beings today.

And the speed of light has also been continuously reduced due to the dimensionality reduction strike, and it has become 300,000 kilometers per second today.

In the third part, those human beings who are lucky enough to enter the four-dimensional space will have an indescribable sense of depression when they return to the three-dimensional universe, which is the so-called three-and-three-hundred-thousand-thousand-dollar syndrome.

The vast and boundless space that we usually feel is not a cage that imprisons us.

The three chatted on the terrace for a while, and the staff came over to tell Pang Xuelin that dinner was ready.

"Professor Ding, let's go to dinner first, and continue to talk after eating."

"Good!"

Ding Yi got up with a smile and, together with Kanter, followed Pang Xuelin into the restaurant.

Dinner is a simple four-dish and one-soup, the chef's skills are very good, although ordinary home-cooked dishes, but always give people a different feeling.

There is a TV in the restaurant, and everyone eats while watching the TV news.

"A few days ago, the Planetary Defense Council (PDC) voted on the "Wall Facer Act", of which thirteen votes were in favor and two abstained, and the "Wall Face Bill" will be submitted to the United Nations General Assembly for consideration in the near future......

"At 18:30 EST, the US National Strategic Missile Defense (NMD) system successfully conducted a test exercise to destroy the low-dimensional Zhizi in low-earth orbit, which was the third test conducted by the NMD system after turning the direction of interception into space, and the target was a reflective film discarded from the International Space Station in October last year. A spokesman for the Planetary Defense Council (PDC) said that the interceptor with a nuclear warhead successfully destroyed the target. The area of the target is about 3,000 square meters, that is, the NMD system is sure to destroy it before the three-dimensional unfolded Zhizi is far from reaching a sufficient area to form a mirror that poses a threat to human targets on the ground......"

"According to a report by our correspondent in the United Nations Secretariat, the United Nations spokesman announced at the just-concluded United Nations press conference that the issue of fugitiveism will be discussed at the recent special session of the United Nations General Assembly, which was jointly promoted by the Planetary Defense Council and the permanent members, aiming to urge the international community to reach a consensus on the issue of fugitiveism and the public ownership of technology, and to formulate corresponding international law!"

Escapism, as the name suggests, means that humanity escapes the solar system before the arrival of the Trimaran Fleet.

Soon after the emergence of fugitivism, many media reported around the world that the United States and Russia, two major countries in space technology, had secretly started their own plans to escape from outer space.

Although both governments immediately and categorically denied the existence of such plans, it caused an international uproar and sparked a movement for "public ownership of technology."

At the third special session of the General Assembly, many developing countries demanded that the United States, Russia, Japan, China, and the European Union make their technology public and provide all advanced technologies, including aerospace technology, to the international community free of charge, so that all countries and nations of mankind can enjoy equal opportunities in the face of the three-body crisis.

The "public ownership of technology" movement received a unanimous response from developing countries, and even supported by some EU member states, but the relevant proposals were rejected at the UN Planetary Defense Council meeting.

Subsequently, China and Russia put forward a proposal for "public ownership of limited technology" at the Fifth Special Session of the United Nations General Assembly, proposing the public ownership of technology among the permanent members of the Planetary Defense Council, which was immediately rejected by the United States and Britain.

The U.S. government says that any form of public ownership of technology is unrealistic and naïve thinking, and that even in the current situation, U.S. national security is still "second only to the defense of the planet."

The failure of the "limited technology publicization" proposal also caused a split among the technological powers, leading to the collapse of the proposal to create a United Earth Fleet.

The repercussions of the setback of the "technology publicization" movement are far-reaching, and it has made people realize that even in the face of the devastating three-body crisis, human unity is still a distant dream.

The "public ownership of technology" movement was sparked by fugitivism, and only by reaching a consensus on fugitiveism can the international community partially heal the rifts that have been created between developed and developing countries, as well as between developed countries.

It is against this backdrop that the current special session of the General Assembly is about to be held.

……

"Actually, we really should seriously consider the issue of escape, and under the premise that humanity's cutting-edge science is locked up by Zhizi, it makes no sense to plan the defense of the earth and the solar system in four and a half centuries. Considering the heights that human technology can reach in the next four centuries or so, the more realistic goal of mankind is to build an interstellar spaceship that will enable a small group of people to flee into outer space to avoid the complete extinction of humanity! ”

In the restaurant, Ding Yi said.

Pang Xuelin smiled faintly and said, "But, who leaves, who stays?" ”

As soon as he said this, the restaurant fell silent again.

Under the premise that the three-body crisis has been announced globally, who will leave and who will stay has become the biggest problem.

In the original book, this issue runs through the era of crisis, deterrence, and broadcasting, and later even the prohibition of human flight under international law.

Until the final Dark Forest Strike came, and the earth humans were completely wiped out, this problem could not be solved.

"Alright, let's not talk about this heavy topic, come on, Professor Ding, Dr. Kanter, let's have a drink!"

"Cheers!"

The three of them clinked glasses lightly and drank them all.

At this time, a piece of news was once again inserted on the TV: "According to the news just received by this reporter, Professor Ji Xingxian, Professor Jiang Zhiwen, and Professor Bu Jiashu, famous aerospace experts in China and academicians of the Chinese Academy of Engineering, encountered a micrometeorite rain during a spacewalk not long ago and unfortunately died ......."

Pang Xuelin was stunned for a while, holding a cup, watching the news on TV, and didn't speak for a long time.

Ding Yi and Kante soon discovered his anomaly.

Kanter said, "Professor Pang, what's wrong?" ”

Pang Xuelin came back to his senses, shook his head and said, "It's okay?" ”

Ding Yi said curiously: "Professor Pang, do you know these scholars who sacrificed?" ”

"No, I don't know, I just feel the danger of space, we want to completely conquer space in the future, and we don't know how many sacrifices we will have to us!"

Ding Yi nodded, and said with a somewhat solemn face: "Yes, now in the aerospace institute, the rocket faction and the non-working spacecraft faction are arguing fiercely, and I don't know if their death will have any impact on this controversy." ”

The corners of Pang Xuelin's mouth curled up slightly, and he didn't answer.

Of course, he knows that this meteorite rain is man-made, and its protagonist is the male protagonist of another dark line in "Dark Forest", and he is also the founder of the future galactic human race - Zhang Beihai!

Zhang Beihai created this micrometeorite rain precisely to kill these old-school academic authorities, so as to ensure that the aercumite faction can gain a real voice in the future space system.

Because the non-working spacecraft is the best carrier for mankind to conquer the stars and seas in the future.

In China, Zhang Beihai is forbearant and introverted, resolute and decisive.

He inherited from his father the unanimous view of the School of Future History (a school of scholars and soldiers who make reasonable deductions about the future of mankind) - that humanity will be defeated!

But on the surface, he showed a firm triumphalist mentality, and even his superiors and colleagues were a little puzzled as to where his triumphalist mentality came from.

However, because of this, he was selected as a member of the future political work task force and went into hibernation.

Two hundred years later, Zhang Beihai woke up before the start of the Dark War, fearing that the fleet would be controlled by the Steel Seal Clan (the Mental Steel Seal, invented by Bill Hines the Wall-Facer), Zhang Beihai, as a human in the Common Era, was chosen to be the executive captain of the "Natural Selection".

However, this is exactly the opportunity that Zhang Beihai dreamed of.

At the moment of taking over the "Natural Selection", Zhang Beihai directly started the spaceship and chose to escape by boat.

At the same time, the Asian Fleet sent four ships in pursuit of the "Natural Selection".

And the results of the Doomsday Battle just proved the correctness of Zhang Beihai's escape.

As a result, the few remaining spaceships of mankind formed starship humans, which became the seeds of future galactic humans.

Although in the later dark battle, several remaining human spaceships broke out in internal strife for survival materials, Zhang Beihai hesitated for a moment and died together with the entire crew of the "Natural Selection".

But in any case, throughout the trilogy, Zhang Beihai's success is unmatched.

Compared with Luo Ji, who has comprehended the laws of the dark forest, this is the savior of human civilization in the true sense.

He has never been officially awarded the title of "Wall Facer", but because of his inner sense of responsibility, he has become the most successful "Wall Facer" of all time.

"Perhaps, if there is a chance in the future, we can cooperate with each other."

Pang Xuelin was secretly worried in his heart.
