Elderly Li Shunji arrives in the underworld after an accident and is assigned to the Fifth Hall of Hell, ruled by a female Yanluo King. When he drinks the Mengpo Soup, everyone is shocked—it has no effect on him. This has never happened before. The Fifth Hall’s Yanluo King, Chu Qinyao, panics. As the daughter of the Fengdu Emperor, her hall ranks last among the ten. If word spreads about the Mengpo Soup failing, she’ll lose her bet and be forced to marry the Western Spirit Emperor’s son, Lord Du.
