At the end of the meeting, the vast majority of people chose the strategic research room under the conditions of medium and low technology, and only Zhang Beihai chose the space war research room under the high-tech level.

In this regard, Pang Xuelin can understand that among the people here, basically no one will really be able to see the strategic decisive battle between human civilization and the three-body civilization in the future.

Therefore, it is of more practical significance to choose a space strategic research laboratory under medium- and low-tech conditions, which is relatively easy to achieve.

More importantly, under the current situation where there are still extensive differences among the major powers, the research of space warfare by various countries will inevitably focus on the low- and medium-tech fields.

In this way, the low- and medium-tech strategy laboratory is also more beneficial to personal development.

Even two hundred years later, the reason why human civilization has formed a political pattern between the international and Asian fleets, the European fleet, and the North American fleet is not unrelated to the current development of space strategies by various countries.

When Chang Weisi announced the end of the meeting, Pang Xuelin stopped Zhang Beihai, who wanted to leave.

"Colonel Zhang Beihai, can we talk?"

Zhang Beihai glanced at Pang Xuelin expressionlessly, and then turned his gaze to Chang Weisi.

Chang Weisi smiled: "Beihai, since Professor Pang wants to talk to you, you can talk to Professor Pang." ”

Chang Weisi took Pang Xuelin and Zhang Beihai to a reception room and said, "Professor Pang, you and Beihai have a good talk, I won't bother you." ”

With that, Chang Weisi exited the reception room and did not forget to close the door before leaving.

Zhang Beihai looked at Pang Xuelin and said lightly: "Professor Pang, is there anything to do with me?" ”

Pang Xuelin said with a smile: "Can you tell me why you chose to study space warfare at a high-tech level just now?" ”

Zhang Hokkaido: "With the technological level of the three-body civilization, we can only fight with them when the spacecraft enters the relativistic speed and has the ability to fly interstellarly!" There is no point in studying space warfare under low- and medium-tech conditions now. ”

"Then you don't have to worry that in four hundred years, our starships will not be able to reach the speed of relativity at all, maybe other people's research will be more practical."

Zhang Hokkaido: "If our starships still can't enter the high-tech level after four hundred years, then no matter how much we study now, there is no point." More importantly, I believe in the potential of human basic science, even if Zhizi has locked our basic scientific research, there is still a lot of potential to be tapped at the application level. ”

"Good!"

Pang Xuelin stood up, paced back and forth in the reception room for a few times, then turned to look at Zhang Beihai and said with a smile: "Colonel Zhang Beihai, are you interested in working in the office of the wall-facing person?" Of course, I'm not impressed, and if you choose to refuse, I respect your choice. ”

If Cheng Xin was by Pang Xuelin's side, he would definitely spit on him at this time.

When the co-author wants to come over by himself, it is part of the plan, and when he is looking for Zhang Beihai, he needs to respect the other party.

Zhang Beihai was still expressionless, muttered for a long time, and said, "I need time to think about it." ”

Pang Xuelin was not surprised, and said with a smile: "I'll give you a day to think about it, tomorrow I will take a special flight to Switzerland, if you want to figure it out, you can go directly to the airport tomorrow to find me!" ”

With that, Pang Xuelin got up directly and left the reception room.

Outside the reception room, Chang Weisi was waiting.

Seeing Pang Xuelin come out, Chang Weisi hurriedly greeted him.

Pang Xuelin said with a smile: "General Chang, I have finished talking with Colonel Zhang Beihai, I have something to do next, so I won't stay long." ”

"Professor Pang go slowly!"

Sending Pang Xuelin away, Chang Weisi turned around and returned to the reception room, and saw Zhang Beihai, who was still sitting on the sofa and contemplating, Chang Weisi said: "Beihai, what did Professor Pang tell you just now?" ”

Zhang Hokkaido: "The wall-facing man wanted me to go to his office, and he said to give me a day to think about it. ”

Chang Weisi frowned slightly, took out a cigarette and lit it, took a deep breath, and said, "Beihai, this is a good opportunity!" ”

Zhang Beihai raised his head and looked at Chang Weisi.

Chang Weisi said: "It is inevitable that the wall-facing person will intervene in the space force plans of various countries, in fact, before Pang Xuelin, the wall-facing Taylor has proposed to come to our army for inspection. Our political wisdom needs to be tested on how to balance the wall-facing plan with the mainstream defense plan. You should know that Taylor, Rediaz, and Hines, the three facers have all begun to form a general staff, and there is no shortage of military personnel from various countries who have been selected to enter the staff. It is the two wall-facing people in our country, Luo Ji lives in seclusion in Northern Europe and does not ask about the world, and Pang Xuelin is immersed in the ladder plan, preparing to send a human brain to the three-body world. Now Pang Xuelin invites you to take up a post in his office, which is a good thing! Moreover, the resources that can be mobilized by the wall-facing people are far beyond our imagination! ”

Perhaps, it was Chang Weisi's last sentence that made Zhang Beihai make up his mind.

Zhang Beihai raised his head and said, "Okay, I agree to go to Pang Xuelin's office to work!" ”

The next day, Pang Xuelin met Zhang Beihai, who was accompanied by Chang Weisi, at the airport.

"Colonel Zhang Beihai, welcome to join our team!"

Pang Xuelin said with a smile.

Regarding Zhang Beihai's joining, Pang Xuelin has the attitude that it is better to come, and it doesn't matter if he doesn't come.

By his side, Zhang Beihai can undoubtedly mobilize more resources and have more space for him to play.

If he doesn't come, then his existence is equivalent to a shadow, even if his plan fails, Zhang Beihai can win a glimmer of hope for the continuation of human civilization in the future.

"Professor Pang, in the future, Beihai is the son of an old comrade-in-arms, and he will be handed over to you in the future! This kid has a lot of thoughts, but he is absolutely sure! ”

Pang Xuelin said with a smile: "Don't worry, General Chang, if I wasn't optimistic about Colonel Zhang Beihai, I wouldn't have invited him over!" ”

……

"It's so beautiful here!"

Cheng Xin got off the helicopter and looked around curiously.

This is a valley with snow-capped mountains in the distance.

Not far away, there is a sapphire-like lake, calm as a mirror, bordered by grasslands and forests, and the fragrance of plants fills the air.

Pang Xuelin, Cheng Xin, Kanter, Zhang Beihai and others boarded the vehicle that came to meet them, and the car followed the asphalt road around the lake and soon came to a European-style manor on the other side of the lake.

At the door of the manor villa, Luo Ji and a fresh-looking woman have been waiting for a long time.

"Professor Pang, welcome to visit!"

Luo Ji smiled, and then introduced: "This is my wife, Lan Yi, Yiyi, this is Professor Pang who told you!" ”

Pang Xuelin glanced at Lan Yi with a strange expression, and said in his heart: Dashi is really awesome!

, Luo Ji fell in love with the goddess of his dreams, and after becoming a wall-facer, he described the appearance and temperament of the goddess in his dreams to Dashi, and Dashi found him Zhuang Yan.

Now, Zhuang Yan's life trajectory has been changed by himself, and as a result, Dashi has found Luo Ji Lan Yi, whose appearance and temperament are not much inferior to Zhuang Yan.

I don't know if this Lan Yi is from the United Nations, or if he was found among ordinary people in the Great History.

Pang Xuelin smiled: "Dr. Luo Ji is so blessed! ”

Luo Ji had a happy smile on his face and said, "Professor Pang, let's go in and talk!" ”

Pang Xuelin and Luo Ji chatted in front, and Lan Yi was responsible for entertaining Cheng Xin and his party.

"I met Dashi in the capital, he should be hibernating soon!"

Luo Ji sighed and said, "I know, alas, Da Shi Na's disease, hibernation now is the best choice." ”

Pang Xuelin nodded and said, "Dr. Luo Ji, do you really plan to live in seclusion here for the rest of your life?" ”

Luo Ji smiled bitterly: "Otherwise, what else can I do, the identity of the wall-facing person is not what I want, it was imposed on me by them!" What's more, I have Yiyi, even if I live here for the rest of my life, I am very happy. ”

Pang Xuelin smiled faintly and didn't speak.

He knew very well that when Luo Ji and Lan Yi's child was born, in a few years, the United Nations would start to put Lan Yi and the child into hibernation and force Luo Ji to perform his duties as a wall-facing person.

It was at that time that Luo Ji understood the law of the dark forest, and sent the coordinates of the star 187J3X1 60 light-years away from the solar system to the universe through the solar wave amplification power function, and one hundred and fifty years later, the star was destroyed by an unknown civilization.

It wasn't until more than 200 years later that humanity observed the destruction of the star, and after the Battle of Doom, realized the importance of Luo Ji and restarted the Wall Facer Act, so that Luo Ji could turn the tide at the last moment.

That evening, Lan Yi cooked a sumptuous dinner for the visitors.

Early the next morning, Pang Xuelin and his entourage said goodbye to Luo Ji and left this paradise.

"Professor Pang, where are we going next?"

On the helicopter, Kanter asked.

"Go to CERN!"

"Good!"

A small town on the outskirts of Geneva, once the world's mecca of physics, but now, it gives Pang Xuelin a feeling of being abandoned for a long time.

The town is still on duty, and CERN is still functioning, but the roads are sparsely populated with pedestrians, few vehicles, and the roads are littered with fallen leaves.

Along the way, you can also see graffiti on the walls from time to time.

"Physics doesn't exist anymore!"

"Physics is meaningless!"

"The universe is no longer the universe we see!"

……

Occasionally, you can see one or two drunks on the street, wandering around with wine bottles.

Under the introduction of the guide sent by CERN to receive them, these drunks are all well-known scholars with the title of professor and doctor of so-and-so university on their heads.

"Since the arrival of Zhizi on Earth and the interference with particle collision experiments on Earth, the LHC (Large Hadron Collider) has been completely abolished, and its original successor, the upgrade of the high-brightness Large Hadron Collider project, has also been stopped, and now there are only a few staff and physicists left behind at CERN, and most of them are either changing careers to other majors or going back to university to teach, and they are not willing to do anything, just like the few drunks I saw just now, who are drunk all day long, and I feel that they are all going crazy......"

The guide at CERN named Ben Turner.

Pang Xuelin nodded with a heavy face, and after a moment of silence, he stopped a drunk man who was wearing glasses, looked to be in his early forties, and most of the hair on his head had fallen out.

"Hey, isn't this a wall-facer? Haha, what are you doing here? Can't find what you're looking for here! ”

The drunk pointed at Pang Xuelin, blew the bottle, and laughed.

Pang Xuelin said: "What's your name?" ”

"Hope Rupert."

The smile on the drunkard's face suddenly retracted, glanced at Pang Xuelin lightly, turned around and left.

Ben Turner on the side said: "Professor Pang, Hope Rupert is a physicist in the former Cavendish Laboratory of Cambridge University, after the three-body crisis came, Cambridge University originally wanted him to go back, he was unwilling, some time ago we were going to dismantle the LHC, this guy is crazy and generally runs to the front of the engineering truck to block it, and also fires the engineering vehicle, this guy is a little abnormal now." ”

Ben Turner pointed to his head.

Pang Xuelin glanced at Ben Turner lightly, looked at Hope Rupert's back, and said loudly: "Mr. Rupert, without the Large Particle Collider, we will no longer be able to study physics?" ”

"Boy, you haven't grown any hair, you know a fart!"

Rupert turned around, looked at Pang Xuelin, and said disdainfully.

Pang Xuelin laughed and said lightly: "I proved the BSD conjecture and the ABC conjecture, I invented Ponzi geometry, and I also solved the problem of solving nonlinear partial differential equations. ”

Rupert glared at Pang Xuelin, and said for a long time: "Boy, don't talk about these useless things, if you have the ability, let the three-body people lift the blockade of Zhizi!" ”

Pang Xuelin slowly stepped forward and said with a smile: "Who said that if you seal the large particle collider, you can seal physics." Are there any auditoriums or classrooms nearby? ”

In the latter sentence, Pang Xuelin said to Ben Turner.

Ben Turner said: "Not far in front of you is where CERN's headquarters are located, and there is a lecture hall in it. ”

Pang Xuelin said: "At eight o'clock in the evening, I will wait for you in the CERN lecture hall, and if you have the ability, you can call all your friends from the physics community who are still in the town, and I will tell you, how to lift Zhizi's blockade of physics!" ”

Rupert glanced at Pang Xuelin deeply, turned around and left directly.

Pang Xuelin said loudly: "Remember, at eight o'clock in the evening, the CERN lecture hall, see you or leave." ”

……

Ben Turner was curious: "Professor Pang, do you really have a way to lift the blockade of Zhizi?" ”

Not only Ben Turner, but Kanter, Cheng Xin and even Zhang Beihai all looked at Pang Xuelin curiously.

If the blockade of Zhizi can be solved, with the outstanding achievements of human beings in the field of culture and art, it is entirely possible that another wave of technological explosion will break out, and by the time the Trimaran fleet arrives in the solar system in four hundred years, maybe human beings will be able to crush the Trisolaran.

Pang Xuelin smiled and said: "I don't have any way, I just want to stimulate them, it's not a matter for these physicists to stay at CERN all the time, their brains shouldn't be wasted in the anesthesia of alcohol for the rest of their lives, I need to convince them to come out and help me do things!" ”
