Du Ming, a young man who was short of money and trapped by the embarrassment of reality, chose to come to the Sea Breeze Bridge and jumped to end his troubled life. He was supposed to fall into the river and die, but he failed to die as he wished. Instead, he was accidentally selected by the mysterious world of rules and ghost stories, and was forcibly transported into the dungeon space to start a strange survival.
When entering the first dungeon, the level of the dungeon was marked as F. The survivors who entered the dungeon together, including Du Ming, all followed the label and assumed that this was just a beginner's dungeon with low difficulty. They put down their guard and faced the challenge with peace of mind. But as the dungeon progressed slowly, the hidden truth slowly surfaced, and everyone was shocked to realize that the dungeon in front of them only had an F-level appearance, but there was danger hidden inside. The true level of the dungeon was the extremely dangerous S-level, and a sudden fatal crisis instantly enveloped everyone who entered the game.
