In 2035, the ecological environment of the earth was destroyed, and more and more natural disasters such as storms and earthquakes caused many buildings to collapse.

To this end, I designed and built a city that can protect the earth's ecological environment and resist all kinds of natural disasters.

The city is built below the ground 10-200 meters, which is called an underground city. Most buildings in the underground city are10-200m high. The entrances and exits of the underground city are all hemispherical buildings with a height of 10, because it can resist storms. There are shopping malls, schools, hospitals, banks, casinos, maglev subways, elevators and so on.

There is an artificial sun in every block of the city, and the underground city is connected by the maglev subway and the underground expressway network, which makes people come and go very convenient and fast. The original above-ground cities have been transformed into forest parks and nature reserves, and the ground has become a paradise for animals.

How to resist earthquakes in underground cities? There is a magnetic sucker at the bottom of the dungeon, which can suck the ground, and there is a straightening device at the bottom. If the ground tilts, it will straighten the house, but it won't fall down anyway.

With this kind of city, people are no longer afraid of storms and earthquakes. The earth has become more beautiful because of the improvement of the ecological environment, and birds are singing and flowers are fragrant. People's lives are better and happier.
