On his way home on New Year's Eve, migrant worker Jiang traveled through the Abyss of Infinite Dungeon, a terrifying dungeon with zero survival rate. When she was in a desperate situation, she discovered that the major bosses in the dungeon were all her relatives, and she relied on the protection of her relatives to survive. However, after clearing the level, I was unable to return to reality. I gradually realized that the words, deeds, and timeline of the duplicate relatives were inconsistent with reality, and I also encountered a cold and cruel parallel self. It turns out that the copy is connected to countless parallel worlds, and she was deliberately involved in the chess game of life and death. In order to return to the original world, Jiang Yu must break through all the dungeons and uncover the huge conspiracy behind the parallel space.
