The modern killer Zhou Huaijin was implanted into the memory of the underworld judge and awakened into the [Netherworld Sign-in System]. During his escape, he could receive heaven-defying rewards such as formations/laser weapons/mecha modifications every time he signed in. He discovered that the Pacific Rim-style crack creatures were actually ancient monsters, and that the Neon Genesis Evangelion troops controlled the Book of Life and Death of the Underworld. The male protagonist with a sunshine attribute uses violence to suppress the conspiracy of the Ten Palaces of Yama. On the surface, he is a degenerate and defecting ghost. In fact, he uses a laser array to destroy the judge's mecha, starting an epic of redemption for his family and country.
