Free Star City was a concept proposed by Yan Xia. His original idea was to be something like an ordinary star city. But Ella didn't think so. It transformed a star city with excellence. This star city is very big, much bigger than it looks. Yan Xia stood on the street and saw an underground escalator. This escalator was very interesting. Each standing place on it existed independently and was not a whole. When you stand on it, it will start to slowly rotate 180 degrees. Why is this happening? Because this escalator leads to the underground world. The entire spherical star city is not only the ground space, but also the underground world. The gravity direction of the underground world is outward, which means that the people outside the star city and the people inside are standing on the same ground. The outside world disappears when you move away from the ground. The underground world is visible more clearly the further away from the ground, because it is convex, just like a basketball. You stand inside the basketball instead of standing outside the basketball. . The so-called ground is actually only a thin layer, probably less than 200 meters thick, carrying the common pipelines of the front and back worlds.
But this spherical star city is more than that. After Yan Xia came to the underground world, she looked up at the sky and found that there was another ground and another city above her head. The two cities are less than 1,000 meters apart, and you can even touch the tops of some high-rise buildings overhead from your own side of the world. "The gravity control here must be very complicated!" Yan Xia marveled at the structure of this star city. If two cities want to reach each other, they need to take a rotating elevator. The elevator flips over during operation and reaches deeper into the city. "That's part of it, the harsh summer." "Don't forget that this is a star city with a diameter of 16,000 kilometers." Yan Xia went to the third city and saw an underground escalator in this city. Sure enough, he took the escalator to the fourth city, and above the fourth city was the fifth city. "Matryoshka doll?" "Don't tell me you applied 10 layers." Ella made a sound of denial. "Of course it's more than 10 floors." "The space used for each layer is actually 1,300 meters, and the radius of Star City is 8,000 kilometers. Excluding the energy storage device in the center, I actually made 666 layers." "Isn't there a legend on earth?" "The bottomless abyss on the 666th floor, where demons live." The 666th floor is actually 1332 cities, or 1333 cities, from large to small cities.
"In this way, we can carry more lives to the maximum extent. Now the population that the entire Star City can carry can theoretically exceed 3 trillion, but I set it at 800 billion." "The only flaw of the entire Star City is that it is unfavorable for fighting against the Orcs. Only the buildings on the surface of the Star City are open to fighting against the Orcs. The heights of the internal buildings are all about 6 meters." It is indeed not very friendly to the war beast tribe, because the average standing height of the war beast tribe is now about 7 meters. The floor height that would make them comfortable would be at least 10 meters, but that would waste too much space, so Ella made some compromises. "But it's actually enough. Star City can survive with a population of 10 billion on its surface, and the War Beast Tribe will not be able to fill it up." Yan Xia thinks this is the best state. The purpose of Free Star City is to connect the star systems of the Federation and lead more creatures into the universe. Ella is really thinking about the role of Free Star City. Not all the space in the entire star city is used for city construction. In fact, if you dissect this spherical star city, you can see a tapered cylinder that continues to expand from the inside out. Expressed on a two-dimensional level, in addition to the central circle, this circle also has There is a sector-shaped area occupied, and the space in this area is the power assembly of Star City. In fact, Star City itself is not a perfect circle. It is actually a flat surface on the side of the thruster. "Does each floor need to have a floor leader?" Yan Xia said half-jokingly. Ella thought about it seriously. "Indeed." "Maybe we can make Liberty Star City a little more entertaining." "For example, people on Star City can gain points by defeating floor masters through games in the virtual world, and these points can be used to purchase some special items in Free Star City." "This way Star City should be more playable." "In fact, every star city in the Federation has similar things. Because now the virtual world and the real world are integrated, every star city is actually equivalent to a new map in the virtual world." "Go to another star city and you can fight monsters with new characteristics." "I heard that some people travel between star cities specifically to collect achievements for killing these monsters, and even go to other star systems to kill monsters in other star systems to obtain achievements." "This kind of people are called achievement collectors, and they are the envy of ordinary people." Yan Xia thought for a while, if she were an ordinary person, she would indeed envy these people. Running around the universe, killing different monsters with different people, it is simply a real-life version of Pokemon. He thought: "Perhaps we can start from this direction and give these collectors some discounts. For example, after completing the complete illustration of a certain star system, we will give him an extra interstellar round-trip ticket, which can allow him to go to other star systems." "There won't be too many of these people, but they should be able to bring some exchanges." Yan Xia will not let go of any possibility. It is imperative to make all aspects of the Federation connected in the star system. "It is feasible. Maybe someone will collect this specifically for the ticket." "But Yan Xia, I think the reward range should be expanded. In fact, there are thousands of monsters in each star city. Maybe we can do this."
"Collect all the achievements of a star city and enjoy a 20% discount on public transportation anywhere in the star system. Collect all the achievements of a star system and enjoy a 50% discount on public transportation within the star city. At the same time, they will be given a round-trip star system spaceship ticket and 1,000 energy coins. " "As for collecting the monster achievements of all star systems in the entire Federation, I think it should be impossible." Not to mention that ordinary people can't do it, even Yan Xia can't do it. The Federation is too big now! "It is indeed possible to do so. Free Star City can also set up some strange monsters to wait for those people to come and collect achievements." "Entertainment has its own advantages." "But Free Star City should also have professional places. Ella, are there any professional research institutes here? Perhaps some scholars will choose to live in a place with high flexibility like Free Star City." Yan Xia asked this question of course for his own consideration. Ella was very particular about this: "Of course there are. Some cities in the 666th floor are educational cities. A large number of research institutes have been set up in these educational cities for scholars to study and use." Yan Xia nodded. Sure enough, he liked this star city very much. It was so perfect. "Are other Free Star Cities like this too?" "Yes, there are currently 37 Free Star Cities in total. It is expected to increase tenfold within 2000 years and strive to exceed 400." Yan Xia felt that there were too many. "Maybe the Federation's population is too small. The Federation has only 110 trillion people now. 400 star cities like this are enough to accommodate half of the Federation's population." "That's not good." "Ella, let's have more birth subsidy policies in the future. We need to reach a population of 100 trillion."
