Outside the real world, there is an infinite world composed of countless nightmare spaces. These spaces are filled with all kinds of dangers and puzzles, and only the strongest and smartest will survive. Every once in a while, some people in the real world will be selected by mysterious forces, enter this infinite world, and be forced to participate in nightmare games one after another. The winner of the game can gain powerful power and mysterious rewards, but the loser will be lost in the nightmare forever and have his soul devoured.
