you come from the sky

Lu Yongan, director of the Institute of Mathematics, Chinese Academy of Sciences, was awakened by a sudden knock on the door.

Lu Yongan breathed a sigh of relief with lingering fear, picked up the balled shirt from the chair and put it on his body, before he had time to button it, he stepped on the creaking wooden floor and opened the door.

As soon as he opened the door, Lu Yongan found that the two people who came to him were very strange.

One of them has a short-shaved head, is thin and tall, like a bamboo pole, young, his face is yellowed by the sun, but his eyes are black and bright, and there is a thin layer of blue-black stubble on his chin. A baggy brown coat with blackened cuffs.At this time, he was standing in front of the door with his arms half-raised—obviously, he was the one who knocked on the door like a ghost early in the morning.

The other one was standing not far behind this "bamboo pole". He looked about in his early 30s and was wearing a light gray shirt.Contrary to the man in the front, the man in the back is meticulous to the point of nervousness, whether it is hair, shirt, trousers, or cloth shoes. He wears an Innag Swiss watch on the hand holding the coat, obviously he is looking for someone. He didn't even lift his head when he heard the door open.

Lu Yongan was puzzled and asked, "What are you doing?"

As soon as he asked, the tall and thin bamboo pole in front suddenly grabbed his hand and shook it like an old acquaintance. The kindness made Lu Yongan almost suspect that they were his old acquaintances.Don't look at this "bamboo pole" man is thin, but his hands are very strong, holding Lu Yongan's hand is painful.Lu Yongan wanted to pull his hand out, but with this movement, he discovered that the hand of "Bamboo Pole" had a thick layer of calluses on the fingertips and the tiger's mouth. This is the callus that only people who often pull the trigger will have.

Lu Yongan immediately became alert, and he intuitively realized that the "bamboo pole" in front of him was a secret service officer!

Lu Yongan retreated vigilantly and wanted to distance himself, but the secret service officer changed the posture of the two of them from shaking hands to a close hug very naturally and professionally, and took advantage of the opportunity to put his head on Lu Yongan's shoulder, " Bamboo Pole" said in a low voice: "It's not convenient here, let's go in and talk."

Who are these two people?Why did you come to him?What did he do?Or come to him to find out what's going on?Lu Yongan wanted to refuse, but he couldn't refuse, so he could only let these two weirdos into his house.

"Live by yourself?" the secret service officer asked as soon as he entered the house.

"Hmm." Lu Yong'an didn't intend to pour water for the guests, and he stood stiffly by the door, looking ready to "please" these two to leave at any time.

"Don't move that!"

"Swiss Watch" is standing next to Lu Yongan's bookshelf at this time, he seems to be very interested in Lu Yongan's research notes, Lu Yongan quickly walked over, squeezed "Swiss Watch"'s arm, and hugged a dozen of his research notes , stood by the window, so that on the one hand, he could distance himself from the two of them, and on the other hand, in case... He meant that in case something really happened, he could jump out of the window and escape.

Leaning against the window, Lu Yongan raised his voice guiltily and asked, "Who are you? I want to see your IDs!"

The secret service officer didn't seem to care about Lu Yongan's pettiness.

He smiled casually and said, "Director Lu, don't be so nervous."

Then came over, skillfully kept a distance from Lu Yongan that would not irritate him, took out the ID and handed it to him.Lu Yongan staggered a bit, if he hadn't touched the wall behind him, he would have fallen to the ground - it wasn't that person's ID that frightened him, but when he just took the ID, even if it was only a short glance, Lu Yongan Yong'an is also very sure that this secret service officer has a gun on his waist.

At that time, although gun control was not as strict as it is now, secret service personnel would carry guns. There are usually two situations: one is that the person has a very high status and is not controlled by general regulations; the other is that they came out with a mission this time Yes, moreover, this task is life-threatening.

No matter what the possibility is, it is not something Lu Yongan can bear.He licked his lips nervously, swallowed twice, and repeatedly stated his name to the two comrades. After repeating, he said: "Comrade, did you find the wrong person? I have just been the director for less than half a year, what am I Do not know at all."

The young "Zhugan" took back his certificate, which showed that his name was Yuan Youbing. Listening to Lu Yongan's appeal, Yuan Youbing smiled and said, "That's right, it's you."

"Did you organize it..." Yuan Youbing, who spoke fluently and professionally since we met, stopped for the first time. He frowned and touched his trouser pocket, and took out a small piece of paper that was crumpled after being tortured for a long time But the note was worn too hard in his pocket along the way, and the line of writing on it that was originally written in pencil is now blurred and only the word "brain" can be recognized.

Yuan Youbing clutched the note in his hand with some embarrassment, like a student who was caught typing a cheat sheet, he looked at his toes and waved his hands helplessly: "That's the one..."

"An answer to the mathematical model of the influence of electromagnetic fluid on the exploration of the internal structure of the human brain." The young man who had been silently looking at Lu Yongan's bookshelf finally spoke.

"That's right, that's right." Yuan Youbing murmured to himself twice, while poking his head with his fingers, trying to remember it, he raised his head and continued to say to Lu Yongan, "Didn't you start a project? It's called about the inside of the human brain...electricity...mathematics...learning..."

After "learning" for a long time, Yuan Youbing didn't remember it. He clapped his hands in frustration, turned around and shouted to the other person: "Director Fang! You can't always count on me!"

Seeing Fang Haochen ignoring him, Yuan Youbing pouted with wide eyes and said, "I found this person for you, you can ask yourself later!"

Fang Haochen withdrew his fingers hovering between the spine of the book, and glanced at his watch——Lu Yongan noticed that he had looked at his watch many times since he entered the room. Generally, this kind of person is either obsessed with time or paranoid about this time " meeting" was impatient.

"You don't need to ask." Sure enough, Fang Haochen said, "He can't."

Yuan Youbing was stunned for a moment, then he walked quickly to Fang Haochen's side with a livid face, pulled Fang Haochen's clothes and whispered in his ear: "You..." He seemed to want to curse, but because of his status, he put The three dirty words squeezed back between the teeth, "What are you fussing about!"

"How long did it take us to come here from 201, isn't it just to find him?!"

"Can't you just say nothing now without asking?"

"Director Fang, you are my ancestor!" Yuan Youbing was like a cannonball, with an angry and helpless tone, "If you don't ask, I can't do business when I go back!"

"I asked, and it was wasting my time." But no matter how outspoken Yuan Youbing was, Fang Haochen remained unmoved.

He glanced down at his watch again, as if he was about to leave.

"Ah, that..." Lu Yongan changed his vigilant attitude just now, and put on a cautious and ingratiating posture, "Are you from 201?"

In the end, Yuan Youbing was provoked by Fang Haochen just now, and accidentally exposed his identity.

Many people may not know it, but Lu Yongan, the director of the Institute of Mathematics of the Chinese Academy of Sciences, knows more or less.

He heard that when the country was first established, a large number of patriotic students returned to the country. With the support of the central government, they set up scientific research projects one after another. If some projects were successful, the impact would be even greater than the atomic bomb and hydrogen bomb.It's a pity that those projects were either too illusory to have any application value, or stagnated due to subsequent turmoil.Anyway, now, after more than 20 years, there are very few projects that are still alive, and the 201 project is one of them.

Lu Yong'an didn't know what 201 was researching, and he didn't know why 201 was able to survive. He only knew that since they were coming to him, it meant that 201's project was related to his research content.

Thinking of this, an indescribable impulse suddenly surged in Lu Yongan's heart. He knew that his thesis might be suppressed for ten or twenty years after entering 201. He also knew that he might leave his hometown after entering 20. He knew even more , Walking into 201, he may not be able to get out for the rest of his life.

But every cell in his body is urging him to join 201.

Lu Yongan has been pondering and researching this scientific research topic for more than ten years, and there has been almost no breakthrough in the past ten years. If it is in 201, if he can use the talents and efforts of the most powerful researchers, his scientific research topic Maybe it really works.

Also... this is an unspeakable secret in Lu Yongan's heart. He has long heard that organizations like 201 have great power. carry.Thinking of this, Lu Yongan's heart was moved. He did have a small "difficulty": at the beginning of the turmoil, his wife took the child and left him, the "stinky old nine" who could be knocked down at any time. For Yu Nian, the mother and son have not heard from each other for more than ten years. If he can join 201, this little "difficulty" will definitely be resolved.

"Needless to say, you can't." But Fang Haochen simply rejected Lu Yongan's wish.

"I..." Lu Yongan still wanted to fight, but seeing that Fang Haochen had already walked to the door, he said hurriedly and tremblingly, "If I can't, my students, a few of my students can also participate, and they all participated There are several projects in this project that are really good.”

This is Lu Yongan's last and most helpless request, but as long as there is one person in his research group who can enter, even if this person is not him, he is willing.

However, Lu Yong'an's begging could not even get Fang Haochen's pity. He walked out of the room in a few steps without even giving him a look.

Yuan Youbing on the side seemed helpless with Fang Haochen, he rolled his eyes and shook his head, and followed him out.

As the two left, the room that had been noisy for less than half an hour quieted down.

The sunlight refracted through the curtains among the dancing dust in the house, as if everything just now was a dream.

It seems that no outsider has ever come, and there has never been a 201.
