In 5070 AD, with the progress of science and technology and the improvement of productivity, human beings on the earth finally ended nearly 10,000 years of division and separation, forming a unified "Earth Federation". Liu Xuan was born in such a new era.

This year is the year 5200 A.D., and one hundred and thirty years have passed since the whole earth became one, and in these hundred and thirty years, mankind has been in a state of recuperation, and the union of the earth has not been smooth sailing.

Knock, knock, knock.

There was a knock on the door, and the force was a little heavy, and it seemed so irritating in the early morning. Liu Xuan struggled to get up on the bed, looked at the watch showing six o'clock with dissatisfaction, and put on his clothes while beckoning to wait.

Today is Saturday, it's hard to rest, who is bothering yourself?

There were two men in black and sunglasses standing outside the door, although they couldn't see the appearance of their faces clearly, Liu Xuanneng could clearly see the horizontal flesh on their faces, and at first glance they were people who had practiced.

Seeing the person dressed like this, Liu Xuan secretly scolded himself in his heart, he was not sober when he woke up in the morning, he knew that he would take a look at the person in the "cat's eye" first, standing outside the door in such a dress, and he would not open the door for them if he killed Liu Xuan. However, now that everything is over, the two big men at the door will not allow the slightly thin Liu Xuan to close the door again.

"Who are you looking for?" Liu Xuan's mind was confused, this room is lived by himself, who else can he find?

"Hello, are you Mr. Liu? Professor Liu Qingyun's son? It was one of the black-clothed people who spoke, don't look at him a little horizontal, he turned out to be respectful when he spoke, which made Liu Xuan even more puzzled, what the hell is going on, what is the situation mentioning his father.

"Hello, I'm Liu Xuan." Liu Xuan actually wanted to say that you confessed your mistake just now, but he mentioned Liu Qingyun, which made Liu Xuan admit his identity after thinking twice. Dad's name hasn't appeared in his ears for a long time, which makes Liu Xuan a little inexplicably kind.

"Then let's ask Mr. Liu to come with us." It's still the same laughing voice, but there is a little unmistakable in the tone. Such a tone made Liu Xuan understand that if he didn't cooperate well, he would have to use some means.

"What are you?" Liu Xuan was talking, but his hand secretly stretched out to the doorknob, Liu Xuan regretted it in his heart, it turned out that someone came to the house to recommend a one-button alarm device, but Liu Xuan didn't even listen and drove people away. Liu Xuan now just hoped that he could quickly close the door and keep these two people out.

Hope is good, reality is always cruel. The man in black obviously expected Liu Xuan to do this, so he directly reached out and grabbed the door, Liu Xuan used his strength to eat, and did not shake the door in the slightest.

"Teacher Liu, we advise you to be smarter. Come with us, we won't hurt you, it's just that the situation is a little special. Another man in black spoke, and this man seemed flat in tone and tone. This feeling is like giving Liu Xuan an order.

Although the two of them haven't taken out any weapons yet, Liu Xuan also knows that if he doesn't cooperate, they may use violence.

"Can I pack my things?" Liu Xuan asked tentatively, his voice was a little loud, he hoped to make noise to the neighbor opposite, so that he would have a chance to be rescued.

"Of course, Mr. Liu, I advise you to pack up comprehensively, it may be difficult for you to have a chance to come back." The first man in black spoke easily, but Liu Xuan was in front of him.

What do you mean by not coming back? Are they here to kill themselves? But what are you doing with yourself talking so much nonsense?

Liu Xuan's brain was running rapidly, but his body didn't dare to stop, he returned to his room, and the two men in black also came in and closed the door with their backhands.

Liu Xuan has always been alone, and if he really wants to clean it up, he really doesn't have anything necessary. The two men in black stood in the doorway, not saying anything. The door has been guarded by them, this room is on the tenth floor, and it is impossible for Liu Xuan to open the window. No matter how you look at it, Liu Xuan has no possibility of escaping.

Liu Xuan had no choice but to decide to take one step at a time, thinking that he was still lecturing on the podium of Heming University yesterday, and he fell to such a point today, it was really confusing.

After cleaning up for a long time, Liu Xuan only had a watch in his hand, which was left for him by his father, that year, he was just ten years old, and his father Liu Qingyun was just thirty-five years old.

Liu Xuan thought about it, and picked up the photo frame on the top of the bedside table, inside was a family photo, a total of three people, Liu Xuan who was held by his father, Liu Qingyun who was holding Liu Xuan with both hands, and next to him was a smiling and happy mother. It all seemed so harmonious.

Liu Xuan still remembers that on the night when he was ten years old, his father returned home in a hurry in civilian clothes from the aerospace base, kissing and hugging his mother and himself, and the joy was something Liu Xuan had never seen before.

"Daddy has been chosen, Daddy is going to the stars!" That was the sentence that Liu Xuan heard the most at that time.

"When are you coming back?" Liu Xuan cares about this, the so-called starry sky, for a ten-year-old child, is just "starry sky".

"Soon." The two-word answer really made Liu Xuan happy, he was afraid that his father would not come back.

It's just that Liu Xuan at that time didn't see the nervousness hidden under his father's smiling face and the worry hidden in his mother's bland look.

Accompanied by his mother, Liu Xuan also saw the successful launch of the "Explorer 1" carrier rocket on which his father and his party were ridden and disappeared into the vast starry sky.

A few months later, due to the rapid deterioration of the environment, in order to clean up the earth's environment first, the "Earth Parliament" passed a resolution to stop funding for the space industry and give priority to environmental management.

In just a few days, the space agency, which had lost its funding, shut down, leaving only a team of a few people to continue to contact humanity in outer space. After decades of governance, the environment has improved, but the space agency still hasn't rebuilt.

The "soon" in Liu Xuan's father's mouth has been a full twenty years now. Liu Xuan also waited for 20 years.

When Liu Xuan was twenty-five years old, her mother also had cancer and left this world, and until the last moment, she didn't wait for any news from her husband, Liu Qingyun seemed to have evaporated from the world.

Mankind has struggled for thousands of years, and apart from the long-term development of weapons, there have been no real changes in all walks of life and in the 21 st century.

Speaking of which, Liu Xuan still doesn't know what the mission of "Explorer No. 1" is.

"Teacher Liu, it's time, it's time to go." The man in black's words brought Liu Xuan back to the display, Liu Xuan nodded behind the man in black, put the watch on his hand, took the photo out of the frame, and put it in his pocket.

After doing all this, Liu Xuan walked up to the man in black and said, "Okay." Liu Xuan's words were so plain, he had put life and death aside, and only in his memories just now did he realize that this world was too cruel to him, and there was no need for nostalgia.

The man in black was a little surprised, they didn't expect Liu Xuan's "luggage" to be so small, so little that they couldn't see it on their bodies.

They still had to act according to the order, and a man in black took out a black pocket in his pocket, put it directly on Liu Xuan's head, and said, "Sorry, this is very important." ”

Liu Xuan did not resist, and let the black pocket be put on his head, and all the light disappeared at this time.

Liu Xuan, who was in the dark, could only feel that the man in black opened the door and led him downstairs.
