Yang Jian is the god in heaven who is in charge of eliminating disasters. He will violently and mercilessly destroy any target that brings harm to the three realms. However, the crisis of spiritual energy depletion in the world is imminent, and Yang Jian falls into the human world. Only by learning to influence the monsters in the world with true emotions instead of violence can he complete his mission and return to heaven as a god. Yang Jian, who has no other talent except violence, finds his his former partner Xiaotian Quan (a black dog), reincarnated as a mortal girl by the name of Wang Xiaoxiao, and begins a monster-hunting operation of unprecedented difficulty.
