Countless people in the world will be forcibly pulled into the infinite space of the treacherous realm and fall into various copies of strange rules. Not everything written in black and white here is a way out. True and false rules are intertwined, traps and lies are hidden, and violators will be killed in strange and ruthless ways. The dungeons progress layer by layer, and people's hearts are far more sinister than ghosts. Only by seeing through the rules and deducing the loopholes can we break free from the prison and survive against the odds in an endless desperate situation.
