The story tells the story of Guo Deyou, a water policeman from the Wuhe Corpse Recovery Team of Tianjin Wei, and his junior brother Ding Mao, who, under the instigation of the wine-drinking monk Li Daleng, investigated the case of a sunken corpse at the Sancha River estuary. They experienced the experience of exploring the haunted building at Weijiafen, seeing the way from the Yin-Yang River Fairy, catching monsters in the Evil Dog Village, and finally caught the real culprit behind the scenes.
