Fabricating The World: Creating A Three-Body Invasion At The Beginning

"Oh my god, how close was it?!"

Cheng Xin looked at Europa going away and asked in shock.

"At the nearest time, it was 150 kilometers away from here, almost passing by."

"There is no way, Jupiter has thirteen satellites, and it is impossible for the space city community to completely avoid them.

"Europa's orbit has a very small inclination with the equator, so this row of cities is very close to each other.

"It is the main water source for Jupiter's urban communities, and there are many industries on it, but once an attack comes, they will all be sacrificed."

"After the sun explodes, the orbits of all Jupiter's satellites will undergo major changes. When the time comes, the space city will have to avoid them, which will be a complicated operation."

Cao Bin explained to Cheng Xin while launching the spaceship he came in.

This kind of spacecraft is extremely small, with a shape and size like an ancient car, and can only accommodate two people.

Cheng Xin was instinctively uneasy about flying into space in such a small aircraft, although she knew that this worry was unnecessary.

Cao Bin just told the AI ​​to go to North America 1, and the spaceship started its thrusters and took off.

In the next three days, Cao Bin took Cheng Xin to visit four more space cities.

The first place they went to was North America 1, which was closest to Asia 1, which was a pure spherical space city.

The biggest advantage of this design is that all areas can receive the same lighting with only one artificial sun in the center of the sphere.

However, the shortcomings of the spherical configuration are also obvious, mainly due to the large differences in gravity at different latitudes.

The gravity is greatest in the equatorial region, and decreases as the latitude increases, leaving the polar regions in a state of weightlessness.

In this way, people living in different areas must adapt to life under different gravity.

The third space city Cao Bin took Cheng Xin to was Europe IV.

Europe IV is the least populated space city, with only 4.5 million people, and is the richest place in the bunker world.

Cheng Xin was surprised to see a large area of ​​exquisite villas under the small sun. Each villa had a swimming pool, and some even had wide lawns.

The tranquil surrounding sea is dotted with patches of white sails, and there are leisurely fishermen beside it.

She saw a yacht sailing slowly by. Its luxury was no less than that of the past Earth. A cocktail party with a small band was being held on board.

She was surprised that such a life could be moved to the shadow of Jupiter, 800 million kilometers away from the earth.

Pacific One can be said to be the opposite of Euro Four.

This is the earliest space city built by the bunker project. In North America, it is also a standard sphere configuration.

Its biggest feature is that it does not belong to the urban community on the back of Jupiter, but orbits Jupiter and is a satellite of Jupiter.

Pacific One is the only city where you can move in freely without a residency requirement.

The city was mainly populated by the unemployed and homeless, as well as many poor people who had lost social insurance for various reasons, as well as destitute artists. Later, it even became the stronghold of some extreme political organizations.

Pacific One has no urban thrusters and no artificial sun inside. The most important thing is that it does not rotate and the city is in a state of complete weightlessness.

Cao Bin did not take Cheng Xin further into the interior of Pacific One because according to him, the social order in the city center was very chaotic.

Gang fights often occur in the city, and a conflict a few years ago actually penetrated the ball wall, causing a serious air leakage.

Later, there seemed to be some unwritten agreement that these conflicts only occurred in the central area of ​​the city.

Cao Bin also told Cheng Xin that the federal government had invested a lot of financial resources in establishing social welfare on Pacific One.

Although most of the more than six million people living here are unemployed, they can still guarantee a basic life.

"What will happen here if the Dark Forest attack comes?" Cheng Xin asked.

"There is only destruction. The city has no propellers. Even if there were, it would be impossible to advance to the shadow zone and run in parallel with Jupiter.

"Look at these," Cao Bin pointed to the large group of buildings floating in the air, "If the city speeds up, all of these will hit the ball wall and cause the ball wall to break.

"At that time, the city will be like a bag with a leaky bottom, so if a strike warning appears, the only option is to evacuate the people here to other space cities."

She knows that compared with the previous era, the bunker world is far from an ideal society.

The great migration to the edge of the solar system has caused the reappearance of some social forms that have long since disappeared. However, this is not a regression but a spiral upward. It is something that will inevitably appear when opening up new territories.

After taking Cheng Xin to see the four space cities, Cao Bin began to tell her about the current political structure of the earth.

Currently, there are 64 large space cities on the backside of Jupiter, Saturn, Uranus and Neptune, as well as nearly a hundred medium and small space cities and a large number of space stations. In the bunker world composed of them, 900 million people live. people.

This is almost all of the existing human beings. Before the attack of the dark forest, the earth's civilization had already entered the bunker.

The political status of each space city is equivalent to that of a country. The four city groups together form the Federation of the Solar System, and the original United Nations has evolved into a federal government.

In history, the city-state era has appeared in all major civilizations on earth. Now, the city-state world has reappeared in the outer reaches of the solar system.

The earth has now become a sparsely populated world, with less than five million people living there.

Those are those who are unwilling to leave their home planet or are fearless of death that may come at any time.

There are also many brave people in the bunker world who constantly travel to the earth for travel or vacation, and every trip is a life-threatening adventure.

But as time goes by, the attack of the dark forest is getting closer, and people have integrated into the life of the bunker world. The nostalgia for their mother planet gradually fades in the busyness of making a living.

There are fewer and fewer people going to Earth day by day, and the public no longer pays attention to the information from the mother planet. They only know that nature is reoccupying everything there, and every continent is gradually covered by forests and grasslands.

People also heard that the people who stayed behind lived like kings. Everyone lived in a spacious manor with their own forests and lakes.

But they must carry guns when they go out to prevent wild beasts from attacking.

The entire earth world is currently just an ordinary city-state in the solar system federation.

"Ah, I have mixed feelings. Our Mother Earth has actually fallen to this end!!"

"Then what can we do? Do we really want to stay on earth and wait to die?!"

"Can't you just push the earth away like inside a little broken ball?!"

"The technology of the Little Broken Ball world can be regarded as Zenith star technology to a certain extent. The formation solidification technology and the fusion reaction technology are both black technologies!"

"Even if you don't mention technology, under the constraints of the laws of the dark forest, if you dare to push the mother planet, then you are just marking the enemy along the way!"

"well"
