"Zhuang Yan, Zhuang Yan!"

Zhuang Yan was listening to a lecture in the classroom when he suddenly heard a shout at the door of the classroom.

Zhuang Yan turned her head and saw that the person who called her was the counselor, and there was a school leader standing next to the counselor.

In addition, there are several uniformed staff members who look like they work in government units and a blonde foreigner.

The old professor who was writing on the board stopped the chalk in his hand, turned his head and smiled at Zhuang Yan: "Zhuang Yan, someone is looking for you, go over and take a look." ”

"Hmm!"

Zhuang Yan nodded, and the life assistant sitting next to her hurriedly got up and pushed Zhuang Yan out of the classroom.

After Pang Xuelin was elected as the wall-facing person, the relevant departments assigned Zhuang Yan a life assistant.

Zhuang Yan is paralyzed in the lower half of her body, she has no feeling below the waist, and she usually needs to be taken care of when she goes to the toilet.

Now, Zhuang Yan has two life assistants by his side, one is in charge of the school and the other is in charge of the school.

Coming to the corridor, the school leader said: "Zhuang Yan, this is the United Nations Development Programme High Commissioner Evander, these two are the staff of the Fangyuan Notary Office in the capital. ”

"Hello! Do you have anything to do with me? ”

Zhuang Yan smiled at them, although she didn't know what they were looking for her, but inexplicably, she felt that this matter was inseparable from Pang Xuelin.

"You're so lucky to be an angelic girl." The UNDP High Commissioner made an exaggerated expression and said with a smile: "Ms. Zhuang Yan, have you heard of the Stars Project?" ”

"Project Stars?"

Zhuang Yan was stunned and nodded hesitantly.

It seems that I saw it on the news two days ago, as if the United Nations is going to auction off stars within a radius of 100 light years in the solar system or something.

But I don't buy stars, why are these people looking for themselves?

Evander smiled: "Ms. Zhuang Yan, congratulations, someone anonymously bought a star for you, the star number is DX3906, 286 light years away from the solar system, the most important thing is that this star is in the clean night sky, it can be seen with the naked eye!" As long as you sign your name on this document, the star is yours! ”

"What? The ...... that this star gave me"

Zhuang Yan felt a little dizzy, an unprecedented sense of happiness swept over her, and her mind turned over and over, leaving only one sentence: "He gave me a star, he gave me a star, he gave me a star......"

Without any doubt, she was sure that the giver of the star was Pang Xuelin.

Next, under the guidance of Evander, Zhuang Yan signed his name on the document in a daze.

"Ms. Zhuang Yan, congratulations, you are the first girl in human history to get a star."

In the applause and envious eyes of everyone, Evander said solemnly.

"Thank you, thank you!"

Zhuang Yan's voice trembled, he choked slightly, and his eyes were red, but the smile on his face couldn't be hidden.

Just ask, for a woman, what could be happier than the person who loves her to give her a star?

In the past six months, she and Pang Xuelin have been getting along day and night, and if you want to say that she has no good impression of Pang Xuelin, it is false.

However, Zhuang Yan at that time did not dare to have too many extravagant ideas.

After all, he will never be able to stand up again in his life, but Pang Xuelin is an internationally renowned mathematician, and the two are very different regardless of their identity and status.

Especially after Pang Xuelin was elected to face the wall, Zhuang Yan extinguished any unrealistic ideas.

It's just that she didn't expect that Pang Xuelin would give herself such a big surprise without saying a word.

In the next afternoon, Zhuang Yan kept looking at his mobile phone over and over, flipped out the address book from time to time, clicked on Pang Xuelin's name, and wanted to dial him.

But when he thought that it was early in the morning in New York, Pang Xuelin must still be sleeping, and Zhuang Yan suppressed his idea of contacting Pang Xuelin immediately.

So she simply found a photo of herself and Pang Xuelin, and looked at it stupidly, the corners of her mouth rose from time to time, flashing a trace of shyness.

When he went home at night, Zhuang Yan didn't tell his mother that Pang Xuelin had sent a star to him.

After eating, she excused herself to be tired and went back to her room to sleep.

Then, she quietly turned off the lights in her bedroom, went to the balcony in a wheelchair, and tried to find the location of DX3906 given to her by Pang Xuelin in the night sky according to an astronomical observation manual given to her by the Commissioner of the United Nations High Programme in the afternoon.

It's just that in this era of severe light pollution, even if it is a rare clear sky today, there are not many stars in the sky.

But Zhuang Yan was not disappointed.

She took out her mobile phone and quietly dialed Pang Xuelin's phone.

Soon, the phone was connected, and Pang Xuelin's slightly magnetic voice came from the other end of the phone: "Hey, Yan Yan!" ”

"Brother Pang, I'm looking at our stars."

Zhuang Yan's voice was sweet, and Pang Xuelin could feel her happiness from the heart at this time.

Pang Xuelin was slightly stunned: "How did you guess that I sent it?" ”

Zhuang Yan smiled: "Except for you, who would give such a gift." ”

Pang Xuelin laughed and said, "Do you like it?" ”

"Hmmm! Like. By the way, Brother Pang, when are you coming back? ”

"It's hard to say, I still have something to do here, I guess it will be a month or two when I'm done."

"Oh." Zhuang Yan was slightly disappointed, but soon became happy and said, "Brother Pang, when you come back, let's look at our stars together, okay?" ”

"Good!"

A shy smile appeared on Zhuang Yan's face.

At this time, she vaguely heard that someone seemed to be looking for Pang Xuelin on the other end of the phone, and said obediently: "Brother Pang, then you are busy first, I won't bother you." ”

"Well, Yan Yan, it's night here, remember to rest early!"

"Good...... Oh, by the way, big brother ......."

"Huh?!"

"I ...... I miss you! ”

After saying this, the phone beeped and Zhuang Yan took the initiative to hang up.

"This girl!"

Pang Xuelin looked at his phone, smiled and shook his head.

The reason why I bought DX3906 and gave it to Zhuang Yan this time is that on the one hand, it can be regarded as a surprise for her, the two planets in this star system can also provide a lot of wealth for Zhuang Yan's life after waking up from hibernation; DX3906, on the other hand, is home to the Living Planet, a galaxy located in a busy shipping lane in the universe where even the legendary Zeroers have been revealed.

According to the statement, the Zeroers may be a group of intelligent individuals, or a civilization, or several civilizations.

But they do exist.

They want to restart the universe and return to the pastoral age.

According to the information that Pang Xuelin got from the world of "Country Teacher", this group of zeroers finally succeeded, and they opened a new universe.

As for where exactly they went, no one knows.

However, Pang Xuelin is sure that if he can get in touch with the Zero, he may have the opportunity to explore the ultimate mystery of the universe.

……

"Alright, let's move on, where did you just go?"

Pang Xuelin looked at Cheng Xin, who was sitting opposite him, and said lightly.

Cheng Xin was a little distracted.

After coming into contact with Pang Xuelin in the past few days, Pang Xuelin did not leave a good impression on her.

The main reason, of course, is that Pang Xuelin used the power of the wall-facing person to force himself to stay by his side, and his attitude towards himself was lukewarm, and his words were fierce.

Once you don't do things well, you will even split your head and cover your face and be scolded.

In addition to this, Pang Xuelin showed the quality of a qualified wall-facing person.

Calm, decisive, wise, and do not drag things out.

But the phone call just now completely subverted the image of Pang Xuelin in Cheng Xin's impression.

She couldn't imagine that this man still had such a gentle side, speaking softly and softly, and the originally hard lines on his face became softer, and he was completely different from when he was to herself.

Are you so annoying?

Cheng Xin secretly complained in her heart, but on the surface, she didn't dare to say anything.

Cheng Xin continued to report to Pang Xuelin on the latest demonstration results of the expert group's ladder plan.

"NASA has just completed two small nuclear explosion thrust tests in space, and the results show that in order to reach the rated speed, the mass of the vehicle can only be maintained at a maximum of eleven kilograms, the radiant sail can be lowered to ten kilograms, and the payload is only half a kilogram, but it cannot be more, because the increase in load will inevitably lead to the thickening of the sail rope, and if the load increases by one gram, the sail rope will increase by three grams, making it impossible to reach one percent of the speed of light."

"The technology of deploying nuclear bombs on the propulsion section of the route is relatively mature. The difficulty is to control the precise interleaving of the aircraft's course with each nuclear bomb, as well as the control of the detonation of the nuclear bomb. ”

"Each nuclear bomb must be detonated at the moment when the radiant sail has just passed over it, at distances ranging from 3,000 to 10,000 kilometres, depending on the explosive yield of the bomb. As the speed of the sail increases, the control accuracy required is getting higher and higher, but even if the speed of the sail reaches one hundredth of the speed of light, the control accuracy is above the nanosecond, which is still possible with the current technology. ”

"Since the aircraft itself does not have any power, its sailing direction is completely controlled by the explosion position of the nuclear bomb, each nuclear bomb on the route is equipped with a position control engine, which is precisely positioned before the sail arrives, and the distance between the two is only a few hundred meters when staggered, and adjusting this distance can make the explosion thrust form a different angle with the sail, and then control the course of the aircraft."

"The radiant sail is a soft membrane that can only tow the payload behind with a sail cable, which makes the whole vehicle look like a huge parachute that is laid horizontally in the direction of sailing, and the nuclear explosion occurs between 3 and 10 kilometers behind the parachute, depending on the yield. In order to avoid the impact of nuclear explosion radiation on the capsule, the sail rope is very long, so that the capsule can lean back as much as possible, this distance is up to 500 kilometers, and the surface of the capsule is covered by evaporative cooling material, which continuously evaporates in each nuclear explosion, and constantly reduces its own weight while cooling down. ”

"Those halyards will be made of flying blade material, only one-tenth the thickness of spider silk, invisible to the naked eye, and a single halyard will weigh only twenty grams for a hundred kilometers, but it will be strong enough to drag the capsule when accelerating, and it will not be cut off by nuclear radiation."

……

Pang Xuelin nodded and said, "It seems that the decision to only send brains is still wise, by the way, how is the selection of candidates for the ladder plan?" ”

Cheng Xindao: "Because only the brain can be sent, considering ethical factors, it can only be found from terminally ill patients at present. However, among the terminally ill patients, it is required to have an aerospace background at the same time, and their mental quality is mature and stable, so the screening is not very smooth now......"

"You say, how about living your brain cut out and send it over?"

"Huh?!"

Cheng Xin's eyes widened.

Pang Xuelin smiled and said: "Look, you graduated from aerospace engineering, and you work in PIA, you have good personal qualities and technical foundation, and psychological quality, barely okay." The most important thing is that with your nature, it is impossible to betray humanity. So what do you think of sending you over and striving for a foothold in the three-body world? ”

"But I'm ...... But I'm healthy! ”

Feeling Pang Xuelin's gaze wandering over him, Cheng Xin had goosebumps all over his body.

She felt that in front of Pang Xuelin, she seemed to be a lamb to the slaughter, and the other party was thinking about where to go under the knife.

"If you don't want to, forget it!" Pang Xuelin shook his head and said: "Actually, if you really can't find a qualified candidate, I have discussed with Vader, and I am ready to start from within PIA, Vadim is the best choice, that guy is an old fritter in the space system, and he has worked in the KGB for many years, and his psychological quality is excellent, the only limited regret is that he still has a wife and daughter who love him...... Gee...... What a pity! ”

"Professor Pang!" Cheng Xin suddenly raised his head and said loudly: "What if...... If you really can't find the right person, then ...... Then don't cut off Big Brother Vadim's brain, just cut mine, I'...... I'd love to volunteer......"

Cheng Xin said, and the tears of the bean fell down.

After working at PIA, Vader was cold and tough, and Pang Xuelin took pleasure in teasing and bullying himself all day long.

These days, PIA's honest Vadim can bring her a little brother-like warmth.

Cheng Xin didn't expect that Pang Xuelin and Vader would be so frantic and ready to attack Vadim.

If Vadim was to go, she would rather go on her own!

Pang Xuelin laughed: "It is worthy of Our Lady Cheng!" ”

"What did you say?"

Cheng Xin raised his head and looked at Pang Xuelin with teary eyes.

Pang Xuelin smiled: "I said just kidding, do you need to cry?" ”

"You?!"

Cheng Xin gritted his teeth and looked at Pang Xuelin, suddenly stood up and said, "Professor Pang, as a wall-facing person, is it interesting for you to bully me like this?" If you tease me like this in the future, then I will quit my job, resign and return to China, find a job and get married and have children with peace of mind! ”

"Yo, I still know how to resist, it seems that I haven't reached the advanced stage of Our Lady's cancer, and there is still salvation!"

Pang Xuelin said with a smile.

Cheng Xin said: "Professor Pang, what do you mean?" ”

Pang Xuelin stood up and came to the floor-to-ceiling window.

His Hilton Hotel is located in the heart of Manhattan, facing the ocean and surrounded by skyscrapers.

The Presidential Suite is located on the top floor of the hotel, and from the floor-to-ceiling windows, the sea and sky are in the distance, and the high-rise buildings spread along the coastline, forming a magnificent picture of industrial civilization.

Pang Xuelin said: "Cheng Xin, do you say that human nature is important or animal nature is important? ”

Cheng Xin was slightly stunned, and blurted out without thinking about it: "Of course it's human nature!" ”

Pang Xuelin was not surprised by her answer, and said: "But the essence of life is the beast, and the beast nature is the driving force for us human beings to stand tall in the world and keep forging ahead. ”

"Huh?"

Cheng Xin looked at Pang Xuelin blankly, and always felt that Pang Xuelin's words meant something.

Pang Xuelin said again: "People, always think too highly of yourself, you see that now we have become the master of the earth, so in order to distinguish ourselves from beasts, we put a halo on ourselves, and call it human nature, how high-sounding, how righteous and awe-inspiring." But we seem to forget that animal nature is the essential reason why we survive on the earth and become the master of the earth. You said that if the universe is similar to our nature, and there are also the jungle among civilizations, and we still communicate with them with human nature, do you think human civilization can survive in this universe? ”

"But...... But ......"

But after a long time, Cheng Xin said: "Professor Pang, if there are civilizations in the world with a higher level of technology than us, their own moral level should not be much worse, right?" ”

Pang Xuelin smiled: "Do you think this conclusion itself is scientific?" ”

Cheng Xin fell silent and did not speak again.

Pang Xuelin said: "Cheng Xin, remember one sentence, it is not easy to survive in this world, fangs are often easier to win people's respect than good deeds." Just like just now, if I keep bullying you, if you keep swallowing your anger and don't know how to resist, then you will always be in a state of pain. You see that as soon as you resist and threaten to resign, my attitude towards you is much better! ”

In the end, Pang Xuelin smiled again.

Cheng Xin stared at Pang Xuelin with a pair of beautiful eyes, his chest rose and fell violently, and after a long while, he said, "Professor Pang, as a wall-facing person, how can you be so brazen?!" ”

Pang Xuelin stepped forward with a smile, patted her on the shoulder and said, "Little girl, you have to remember that being brazen is exactly the basic requirement of a wall-facing person. ”

As he spoke, Pang Xuelin shook his head, walked past Cheng Xin, and returned to the sofa area.

Behind him, Cheng Xin's low retort came: "You yourself are not a few years older than me, what are you pretending to be old-fashioned!" ”

Pang Xuelin staggered, turned his head and stared at Cheng Xin viciously.

Cheng Xin was startled, and hurriedly said, "Professor Pang, if there is nothing else, then I'll go first." ”

"Well, let PIA speed up the screening process for candidates for the Ladder Program. Oh, by the way, didn't you graduate in aerospace? You can see if there are any suitable terminally ill patients among your classmates, and if so, recommend a few to come! ”

Cheng Xin, who was about to go out, was slightly stunned, turned around and said, "Professor Pang, please don't curse my classmate to death!" ”

With that, she left the room without looking back.

Seeing Cheng Xin's back disappear behind the door, Pang Xuelin smiled: "This girl, after training, she has really grown a little." ”

At this time, Kanter walked in and said, "Professor Pang, we have rejected Yun Tianming's application to buy Stellar according to your request, and this is Yun Tianming's personal file, please take a look." ”

Pang Xuelin nodded, took Yun Tianming's file and looked at it.

Kanter was curious: "Professor Pang, this Yun Tianming ......"

"Oh, it's okay, I just want to see if Cheng Xin's relatives, friends, and classmates have qualified candidates for the ladder plan, after all, after the implementation of the ladder plan, if the people we sent over can really gain a foothold in the three-body civilization, it will have a crucial impact on the future of our human race. Therefore, it is better for the candidate to have some kind of relationship with the people we are familiar with, so that the future is also easy to control. ”

"Oh!"

Kante nodded, not saying anything more.

Kante didn't know how to describe Pang Xuelin.

In fact, so far, among several wall-facing people, Pang Xuelin is the most unpredictable.

Needless to say, Luo Ji really plans to use the authority of the wall-facing person to eat and wait for death to live in seclusion in the mountains for the rest of his life.

The remaining facers, Taylor, Rediaz, and Hines have all formed their own staff, and their plans are also progressing steadily, and they seem to be relatively reliable.

Only Pang Xuelin, after taking up the position of the wall-facing person, plunged headlong into the ladder plan.

But even if this plan is successful, will it help humanity to win the battle one day?

Kante didn't see it until now, anyway.

And Pang Xuelin seemed to have fallen in love with Cheng Xin, a beautiful girl from PIA, and used administrative means to directly stillinstate Cheng Xin's suitor's star delivery plan.

Even so, Pang Xuelin didn't seem to be at ease, looking at his current appearance, he was ready to cut off the brain of Cheng Xin's classmate and send it to the three-body world.

If it is said that in the past, the impression that Pang Xuelin left on Kanter belonged to the typical image of a scholar, gentle as jade, calm and wise.

But now, Kante couldn't read it, he couldn't even think of what this wall-facing man was trying to do.

Does he also want to be like Luo Ji and use the wall-facing plan to pick up girls?
