Danzi boys Dan Xiaohuang, Mao Duoduo and Puff took shelter from the rain on a rainy night and accidentally entered the barrier of a midnight convenience store, falling into a strange secret realm of infinite reincarnation. Following clues and relic fragments, the three of them passed through four secret rooms: an abandoned kindergarten, an ancient temple in the mountains, a stranded cruise ship, and a clock shop in the old city, gradually uncovering the truth behind the demise of the previous generation's treasure hunting team. The faceless clerk is the only remaining survivor from that time, just a gatekeeper who has been imprisoned by the barrier for a long time. The three of them work together to solve puzzles and overcome levels, grow up side by side in rules-based adventures, rely on courage and tenderness to resolve obsessions, break reincarnation, and bring about a reversal story of warmth and healing.
