World view rules: In the 22nd century, humans discovered the ruins of "Leye City" in the deep sea, the core of which is the living server "Brain of Cthulhu". The server will absorb the consciousness of those who come into contact and convert it into a data stream to feed the sleeping ancient god. The cognition of those who come into contact is gradually contaminated, and everything they see and hear is distorted into a mixture of flesh and technology. The "Civilization Preservation System" bound to the protagonist is actually a creation of the ancient god Nyarlathotep, who induces humans to activate the server by issuing tasks. System rewards are actually catalysts for cognitive pollution.
