In the suburbs, the city's third cadre sanatorium is built on the edge of a park and shares a green space with the park. In the middle is a low fence with an iron gate. The veteran cadres of the military region who recuperate here often pace out to enjoy the beauty of the sunset, feed fish, or say hello to the pigeons on the grass.

A wheelchair was pushed slowly from a distance. The little nurse pushing the wheelchair was texting her lover with a mobile phone in one hand, and didn't care about the surrounding situation.

The old man sitting in the wheelchair looked old and his hair had lost very little. Each one was like a silver silk thread. He combed it orderly towards the back of his head, revealing his wise broad forehead, and his face full of gullies was full of traces of years.

The old man was covered with a thick blanket on his knee, and his eyes closed slightly, like a half asleep posture.

Outside the garden, a military jeep stopped. Lin Tao got out of the car and walked straight towards the old man. Behind him was a guard, who followed Lin Tao with a small step.

"Is that the old gentleman?" Lin Tao stood in front of the old man and politely took off his military cap.

The old man didn't speak. He silently looked at the distance. Instead, the little nurse behind him put away his mobile phone and asked, "are you? It's not time for us to visit. Please leave!"

"You!" ordered the guard, in a quiet but powerful voice. "Do you know who this is? Come with me!"

The little nurse was also a person who had worked in the military region sanatorium for several years. After this reminder, she saw the flowers on each other's shoulders and was so scared that she stuck out her tongue. So she stepped on the brake of the wheelchair and stood aside with the little guard.

Lin Tao waited for the two men to go away before he asked again, "are you that old man?"

The old man was noncommittal, still with a dull face, tilted his mouth and looked at the distance behind Lin Tao. His eyes were a little dull

"Ha ha... I know that for everyone here, you are just an ordinary retired veteran. Those people of the Ministry of national security hide your true identity so that you can spend your old age in peace. Coincidentally, I happen to have several friends in the Ministry of national security, so it's not difficult to find you..."

Lin Tao smiled: "and according to my investigation, you are not as forgetful as you appear. My people found the go game you play every night in the computer in your room. According to the progress of the game, your old stage is quite high!"

"Just say it, what do you want to ask?" the professor suddenly smiled, and the pretended foolishness in his eyes was swept away, but he didn't seem to appreciate each other's self cleverness.

"Commander He Gang died..." Lin Tao said very politely, "now, I am responsible for taking over the whole biology department. I know he is only the second head of Super Brain laboratory, and this base was established by you alone. Therefore, please give me some advice on some questions you don't understand!"

"Oh, I don't know you, but I'll give you five opportunities to ask questions." Professor Naduo smiled.

"Thank you. The first question I want to ask: it's just a supercomputer copied based on the data of alien civilization, but no matter how advanced, it's essentially the same as our computer, isn't it?"

"Yes..." Professor Naduo's nostalgia rose. "It's just a data storage and output device. Even if it shows the intelligent illusion that it can answer with us, it doesn't have the ability to think and self-consciousness. It just answers our questions according to the information in the database."

"Well, the second question... Who and how is the knowledge contained in it stored?"

"Well, in short, it is based on the light wave information received by our launched satellite in space, stripping the background light through some specific methods, reducing noise, then decoding the resources, and then inputting it into the terminal device... As you know, sunlight has seven colors. You can regard it as a unique Hex language, and the flicker of each color light Information with different frequency composition is not easy to find without prompt. After transcoding, the hidden important technical data and all resource information are stored in Tianhe for ready access... "

"Why do aliens hide such important information in the sun?"

"In fact, it is not intentional hiding. First, in terms of efficiency, only light can spread at the fastest speed in the universe. Second, if this kind of transmission is aimless, in such a vast universe, light will also be consumed during transmission, and the possibility of being received is almost zero

Just like you shoot the enemy with a gun, you can't close your eyes and shoot around?

Therefore, for them, the best way is to send the signal purposefully to the center of all possible life planets - stars, and then use the huge energy jet of the star itself to amplify and reflect the signal to the stars rotating around it,

This is a very clever way, but it is possible that for millions of years, mankind has been bathed in such an ocean of knowledge without knowing... "

"Well, the fourth question..." Lin Tao paused thoughtfully, then squatted down in front of many professors and stared sincerely into each other's eyes, "can it... Lie?"

Professor Naduo's body shook slightly in his wheelchair. For 30 years, since the establishment of super brain, this question that has been lingering in his mind was finally asked by another equally intelligent person.

"According to xingweike's monitoring and calculation of the super brain, it is only a terminal output device of internal data, that is, it does not have thinking and self-consciousness - it will not lie!"

"I noticed what you said, but xingweike's opinion..."

"Hehe, you're very sharp. My personal opinion doesn't matter..." the professor hehe smiled. The two looked at each other for a moment. Suddenly, they both smiled. Lin Tao nodded. This was basically the same as his guess. He stood up and respected the professor with a standard military salute to show his infinite admiration for the elder.

In terms of feeling, Xu Zhe is more like He Gang, good at power and politics, while Lin Tao is closer to that. As someone said, similar people have the same temperament and will naturally attract each other, that is, people flock together and birds of a feather flock together.

"You have another question, don't you want to ask?" nado also keenly felt the intelligence and sensitivity of the young man in front of him, which was really like when he was young... So he felt some closeness to him.

"This question involves your personal position. You can choose not to answer: Why have many bioengineering materials been modified in the notes you left to the Institute?" Lin Tao asked politely.

Professor Naduo smiled: "even if I don't modify it, they can't complete the research. The so-called modification is just to give them an illusion, or... A beautiful fantasy. Imagine that as long as you get the correct data, you can complete the experiment, prolong human life to infinity and have a beautiful dream, isn't it?"

"You mean... Even you don't know how to prolong human life. The problem of genetic code is unsolvable?" Lin Tao looked thoughtfully at the wrinkles on the faces of many professors. Indeed, if a person mastered the secret recipe of living for thousands of years, how could he wait for his life to wither in this wheelchair?

"Or, there is another possibility - you don't think human beings should prolong their life, you should die with this secret!" Lin Tao asked tentatively.

The professor shook his head and smiled strangely. He was noncommittal and waved to the nurse to push himself back.

Lin Tao watched the professors leave. The sun came from the old man's ear, making the back look so ethereal and unreal

Suddenly, he remembered something and asked loudly, "why should alien civilization help us?"

The professor's voice came from a distance: "you have asked five questions..."

Lin Tao angrily flattened his mouth. He regretted that he should have asked this question first. It seems that he made a mistake. He turned around, turned his back to the setting sun, greeted the guard, and let's go

At the moment of turning around, suddenly, a dazzling reflection from the grass in the distance reflected into his eyes. After all, Lin Tao grew up in the army and worked in army weapon research and development for several years. At that moment, he realized with experience that the size and intensity of the reflection was a sight!

And I happen to be on this reflective track with many professors!

"Get down!" Lin Tao shouted. He could only throw down the guard nearby. Almost at the same time, two dull sounds of "bang bang" swept through his ears.

Lin Tao took out the May 4th pistol from his waist. While rolling, he aimed at the direction where the gunshot sounded and fought back. The flash did not shine again. Instead, a figure rolled from the grass and disappeared behind the low brick wall like a civet cat.

"Catch up with him!" Lin Tao ordered. The guard jumped forward, then bounced up and chased in that direction like a rabbit.

These guards are first-class special combat personnel selected from thousands of miles in the army. They are agile and have excellent shooting skills. Ten or eight ordinary people can't get close to them at all.

Lin Tao turned his head and ran to the old man, but it was too late

The shot was very accurate. Lin Tao estimated that the distance from the flower bed to here was at least 150 meters. The bullet came from the gap between the female nurse's arm and waist and directly penetrated the professor's heart. The shooting interval between the first shot and the second shot was less than half a second, and the shooting position between the two shots was only half a centimeter away. Moreover, The shooting position is still a strong backlight area that ordinary snipers will never choose!

Lin Tao held the fallen professors in his arms. The blood on his chest was pouring out like a spring. A lot of blood was also gushing out of his mouth and nose. Lin Tao knew that it was late, really late

Professor Naduo raised his hand, grabbed Lin Tao's skirt with his last strength and said with difficulty: "... There are two... Two..."

"What? What has two?" Lin Tao instinctively felt that it was a very important sentence, but the voices were very weak. The second half of what he wanted to say was drowned by the blood gushing from his throat. Behind the two people, a dirty disabled little beggar was struggling to climb over, hugging the old people and sobbing

Lin Tao didn't care about this. His thoughts were entangled by the last sentence of many professors, like a mess of hair, two? What has two?

In his hand, he tightly held a small memory, which was secretly stuffed into his arms by many professors at the last moment. Although he didn't know what it was, he knew that this thing was extremely critical!
