Dai Chuxi accidentally fell into thousands of strange lands built by human obsessions. Each foreign land is a dungeon that risks his life. The copy has its own set of cruel rules. Illusions and traps are hidden in the dark. Those who fall will be trapped in the illusion forever.
Along the way, she met three companions: Qi Wanjia, who is good at deducing rules, Ao Yan, who is strong in close combat, and Shen Yici, who can see through illusions. The three of them served as her backing, accompanying her through numerous dungeons such as taking pictures in a bamboo house, obeying orders in the market, and being a ferryman in the foggy river. Dai Chuxi relied on his keen insight to solve the puzzle of the dungeon. He grew up in the situation of life and death, constantly collected clues, uncovered the secret of the birth of the dungeon in the alien world, and found a way to break the illusion and return to reality.
