This world is very chaotic. After a human dies, he will turn into a ghost. Some are good ghosts, and they will go to Luoshan Gate; some will turn into evil ghosts, and they will stay in the world, wandering around, harming the world, and causing many things. Human beings do not believe in ghosts. Human beings regard these things as just a little weird. However, because of these ghosts, a kind of people appeared. They were called death hunters. However, most people did not know them.
