One day, the "Ghost Story" system suddenly descended on the world. Everyone will be randomly pulled into a strange dungeon and must abide by the rules of the dungeon. Anyone who violates it will die. Dungeons are divided into different levels (D, C, B, A, S). The higher the level, the more terrifying it is and the more generous the rewards will be.
At the same time, a "copy of the national destiny" is opened between countries - each country sends representatives to enter, and the performance directly affects its own resources, living environment and international status.
Imagination can be very beautiful
