AD 2242. Humanity has built miracles. This miracle is called "Jianmu". It is an orbital elevator. Its base "Kunlun" is located in western China. It is like a giant vine reaching up to the sky and the earth, connecting the surface of the earth with the "Yaochi" space station in outer space. Through it, humans can enter the universe cheaply and efficiently. A new golden age seems to have arrived.
