Ghost Contract

Terror is resurrected, ghosts are rampant, ordinary weapons are invulnerable, and it is difficult for humans to survive! Later, someone proposed the theory of "demon killing demons"! They think that since human weapons cannot harm ghosts, can they themselves kill themselves? After constant attempts and efforts, humans finally found a way, and that is--Ghost Contract! After a hundred years, humans finally have the ability to protect themselves and fight back! This novel and its characters are purely fictitious.
