Wei Xian: I Am the Great Terror

When Li Guanqi woke up, he found that he was tied to a bone altar, and a group of black-robed lunatics were about to sacrifice him to an evil god called the "Thousand-Faced Moon." The system was long overdue. Welcome to Thousand Faces Moon Simulator [Current script: "The Secret of Enlightenment of the Black-blooded Monster"] [Simulation starts——] Relying on the simulator to repeatedly read files, predict the future, and extract entries, Li Guanqi fought his way from the altar to join the sect, and gradually established a foothold in the cannibalistic world of immortality. But he gradually realized something was wrong. Every time the simulator is used, it accumulates "Tao-tainted values", and the pollution goes deep into his bones. He begins to see things he shouldn't see - worms in his aura, his reflection smiling at himself in the mirror, and the moon with human faces in the sky. What's even weirder is that every script he simulates points to the same buried ancient truth. The Moon Servant came to his door, bowed respectfully to him, and said something that made his hair stand on end: "You've been missing for too long. We've been waiting for you to come home."
