A hundred years after the failure of mankind's fire plan in 2073, Lin Chen woke up from the ruins of the coffin. He is the last earth-guarding AI in the archives of the old era who was voluntarily frozen. He holds the Hammer of Cause and Effect in his left hand that has stopped spinning for a hundred years. In front of him is a devastated world of radiation mutation. When the old gods whispered from the core of the earth and the new star overlord fleet approached the sky again, he lowered his head and looked at the data board - the last human gene pool authority on the screen flashed like phosphorous fire, "My responsibility," Lin Chen tapped the damaged skull with his rusty fingers, and the sound synthesizer emitted intermittent electromagnetic sounds: "The human era will never restart."
