Wutang was framed for multiple crimes and was sent to the Sin Domain to undergo twenty dungeon trials in exchange for freedom. Wearing a supervision collar, he passed through many strange dungeons and got acquainted with the irritable and protective refugee boss Kasluoge, the mysterious 12th princess Yuan Yu, and conquered the kind-hearted ghost Xiu Di Qiu.
In the dungeon, Wutang not only has to solve strange puzzles and deal with all kinds of dangers and strangeness, but also has to deal with the rules of the sin domain and the disputes in the twelve domains. He gradually discovered that the Sin Domain hid the forbidden magic conspiracy of man-made ghost cultivators, and Yuan Yu's true purpose and the power game in the Twelve Domains gradually emerged.
The trio formed a bond in the trial of life and death. The fateful entanglement between Wutang and Yuan Yu, and the fight side by side with Kasluoge, were intertwined with dungeon puzzle solving, power struggle and emotional warming. As clues such as Tianlingjing's Evil Suppression Tower and Geyou Tower's Suspense Cloud emerge, a greater crisis concerning the balance of the Sin Domain and the fate of the Twelve Domains is quietly approaching.
