The long intellectual and moral separation between man and nature form the basis of the problems we humans have with nature. The negative effects of human activities on nature will bring the end of the world after a while, and this is no longer something that human beings can bring back and correct. History repeats itself and man seeks a way to live. People living in the distant future start to live in cities flying in the sky, which we now call Skyland, due to the destruction they have created in the world. They continue their research and observations in laboratories in order to establish a new living space where they can meet all their basic, social and physical needs, such as cafe-restaurant, conference hall, exhibition area, shopping areas, etc., and to continue their lives.
