[23 years of the era of crisis, the way home]

It's still the same city. The city floated on the back of Jupiter's bunker, and the structure was barrel-shaped, with a slight curve in the middle, and people lived on the inner side of the cylinder. Yuantong is not fully enclosed, the circular ground at both ends will leave space to the outside, and at both ends are helipads, where various spaceships are parked.

Liu Shaoming lives in a villa and lies on the top floor of the villa, which is also a comfort zone. Lying on a chair, looking through the glass at the slightly curved greenery. The grass is particularly fresh and natural, and there are many green trees dotted with it, which seem to be greener than on Mars or even on Earth in the past. The only drawback is that there is no sky in this world, just because heaven is earth, earth is sky, and the city itself is a cylinder. Liu Shaoming looked up, it was still a large piece of grassland, a slightly curved surface, very similar to the Hulunbuir grassland of the earth in the past, but after looking at it for a while, he was a little dizzy.

The child suddenly opened the door of the upper floor, stepped into the comfort zone, and stared quietly at the cylindrical city.

"Dad, why don't the trees and grass fall down on it?" The child innocently asked, the world is a fairy tale for him.

"Because of gravity, we're sucked in by what's underneath. They are also sucked in and can't fall. Liu Shaoming smiled and said that he was impressed by the child's innocence. In fact, what Liu Shaoming said is not quite right, because this is not real gravity, but the child lacks knowledge, so he can only tell him so. The city itself rotates, and the centrifugal force it creates mimics the gravitational force that people experience on Mars. So everything is the same as usual, the grass and the trees are clinging to the inner wall, not falling and not floating upwards.

"Son, we'll go back to another home together in a few days." Mr. Liu said that the other home he was referring to was the home of Mars. Since the tachyon strike did not take place in the end, the Solar System Fleet's search team later went to the asteroid belt and destroyed the launcher, only to find that the Earth rebels had fled, and the location of the launcher was empty. The search team later thought that the emitters had been built in many places, and searched the entire solar system on the Internet, including eight planets and Pluto, and found no other tachyon emitters. Eventually, the federal government informed the world of the news, and the vast majority of people were on their way home to Mars, with only a small percentage willing to stay in Space City.

"There?"

"Well......" Liu Shaoming thought for a long time, and had been struggling to choose the right words, words that could be explained to the child, "Go to Mars...... It's another planet. ”

"Wow! It's awesome that we're actually going to live on another planet. The child happily said, "Is it the Cute Eye Planet?" ”

Liu Shaoming was stunned, he didn't know how innocent and childish the child's world was, how many novel and wonderful things there were, but in fact, it was more ignorance in his heart, "No, go to Mars." I still have my mom, and other people have lived on planets, including you...... months. ”

"Is Mars all fire? Wow...... Don't, don't, I don't want to go to the planet with fire. ”

"Mars has no fire." Liu Shaoming patiently explained, and then ordered the smart worm to collect things. After hearing the command, the intelligent worm walked out of the container, then crawled through the container in a winding way, transformed into a human form, and then walked up and down the stairs. Intelligent insects, also known as "particle clusters", are composed of black, finger-sized man-made particles, which can be combined by themselves through some kind of connection, like pairs of swarms of ants, which can be connected together with their bodies to build bridges. Even if they were to break it apart one by one and throw it in all directions, they would quickly come and connect together, and there was a kind of force field connection between them. Moreover, a single particle has the ability of deep learning, in short, it is as intelligent as a human.

Soon, a large package was enveloped in a cluster of black particles. Then put it on the flying car outside the house.

"We're going home." Liu Shaoming said, not forgetting to take a few more glances at the villa, and then added, "I will come back to live if I have the opportunity in the future." With that, he took the child by the hand and walked into the car.

The wife was already in the car, and the wife came back from her daze at this time, took the child from Liu Shaoming's hands, and held it in her arms. Then he turned his head to look at Liu Shaoming, "Let's go." ”

……

The journey is short, and it will not take long to reach the vacuum tube train station. There were a lot of people on the platform, and everyone was carrying a big bag, a big suitcase. Some people have nothing on their hands, they are wearing designer coats, followed by an intelligent robot, with luggage on their shoulders, hands, and heads. There are also men, and from time to time there are women next to them holding their arms. There are more people than ever, they are all waiting for the train, they also want to go to Mars, oh, back to their old home. The light particle strike is gone, so there is no need to hide behind cover, they are the ones who went back to Mars. The electronic stop sign suspended in the air reads:

【Yuyu District - Apron A】

The green handwriting on it is clear and clear, lying quietly in the border of the stop sign, the border is blue, and the shape is very similar to the box pulled diagonally by the mouse on the computer.

The train arrived at the station at a very fast speed, and there was no deceleration process in the process, and it was difficult to see even the movement process. Looking at the train from the perspective of the people on the platform, it seems as if the train appeared in the same place and instantly.

At this moment, the door of the vacuum tube surrounding the outside of the train slid open, and at the same time, the door of the train also opened. So, Liu Shaoming took Lin Xi's hand, Lin Xi took the child's hand, and the three of them entered the train in parallel.

From time to time, the train automatically closed the hatch without detecting a person, and the outside vacuum tube was also closed, and the sound of the vacuum tube expelling gas sounded outside the train. At that time, when passengers came in, some air penetrated in, so the gas had to be exhausted before the train started.

After the gas was exhausted, the maglevitating train in the vacuum tube started, and after a continuous acceleration, the train sped towards the tarmac at a speed of 700 kilometers per hour, and the view from the windows was difficult to see.

……

In the middle of the night, Liu Shaoming's family was already sitting on the spaceship, the spaceship slowly moved away from the space city, Liu Shaoming couldn't help but look back at the magnificent space city, it was a huge cylinder, from the entrance and exit of the space city, you can also see the spaceships inside, and a little bit of grass. There were also many, many spaceships flying out of the entrance, like wasps coming out of the nest, and they also embarked on the way home to Mars.

It's time to go home.

"Look, kid, our hometown is there." Liu Shaoming said faintly.
