The surface of the earth is radiated, and human survival depends on a hallucinogenic fungus called "Psychic Spore", which is both an energy source and a hallucinogen. Long-term consumption will cause physical changes. The city in the sky "Zion" is absolutely isolated from the wasteland "Area 9" on the surface. Air, water, and even "hope" are scarce resources rationed by class. "Everything has a price, and if you don't have money, you are just an animal." The world runs on an extremely strict "psychic credit" system, and the law has been transformed into a "business contract." Killing and stealing can be legalized as long as sufficient "liquidated damages" are paid. The "stealing" ability of the protagonist Lin Qi is the most complete blasphemy against this set of money-oriented rules. In order to adapt to the high-intensity "rule analysis", he is gradually losing his "human" emotions and becoming numb to pain, fear, and love. This "dehumanization" is not only his weapon, but also a hidden danger that he may eventually degenerate into a monster.
