In the twenty-sixth year of the Republic of China, Foshan Town in Lingnan was hit by heavy rains. The corpse of Yizhuang disappeared mysteriously, and the beggar from the ruined temple died suddenly and mysteriously. Corpse charms and corpse oil pottery pots with the word "Xuan" engraved on them were left at the crime scene - this was the handiwork of "Xuanqing Taoist", the culprit of the Peking massacre three years ago.
Detective Lin Zhenghong possesses the secret skills of Taoism. He uses a compass to distinguish yin and yang and a peach wood sword to kill evil spirits. He is both a law enforcer and an exorcist. He quickly saw through Taoist Xuanqing's conspiracy: the other party wanted to find nine corpses with special horoscopes and refine "nine-turn corpse puppets" that were invulnerable and could help them live forever.
From chasing corpses on rainy nights, searching for clues in Huichun Hall, to confronting corpse puppets in mass graves, Lin Zhenghong pressed forward step by step, but was repeatedly thwarted by Taoist Xuanqing's strange magic. As innocent people die one after another, he not only has to decipher the secrets of the Xuanyin sect's corpse refining, but also faces the police's doubts and people's panic. He also discovers that there is a deeper dark conspiracy behind this evil magic, and a life-and-death battle between good and evil begins.
