In this world, monsters are getting more powerful, but no matter how strong they are, they disappear in this mental hospital. Some even lose their dignity and become food ingredients or pets. We're talking about the Green Peak Mental Hospital, which is full of talents and powerful warriors. Lin Fan, a patient with severe mental illness, acquired a system one day. He claims that he's not mentally ill. He's just a normal person who enjoys cultivation. He's only got simple hobbies like sticking wires into sockets, climbing onto electrical transformers, and standing on the roof to wave a metal stick when it thunders.
