In the future world of 2190, due to the destruction of the earth, humans have created a virtual universe based on the core left by alien civilization, and everything generated in the virtual universe is an entity, and both AI and humans can use it. At that time, humans had developed a certain degree of hive consciousness. There was no longer war between humans, but unity. The virtual universe is divided into the first world, the second world, the third world, the fourth world and the zero world. The zero world is a world in nothingness. It was originally a good AI world, but later collapsed due to immature technology and was used to suppress some AIs. The first world is the main world where humans live. The second world is the experimental AI world, with various immature AIs. Most of the meaning of AI comes from here. The third world is a paradise created by humans for AI, making AIs think that they are very free. The third world is just an appearance.
The novel tells the story of Yuma who first helped humans, then was moved and started to help AI. In the process, he was deceived again but found that he was deceived by AI.
