Shen Mo, a heir to a family of metaphysics who appears as gentle as jade but is actually sinister and cunning, was forced to marry Chu Qingli, the eldest daughter of the Chu family who was rumored to have killed her three fiancés due to an unexpected "substitute marriage" incident. On their wedding night, Chu Qingli turned into a ghost and demanded her life. Shen Mo used a soul-suppressing talisman to suppress her, only to discover that the "bride" had the remnant soul of an ancient evil god sealed in her body. What's even weirder is that the real legitimate daughter of the Chu family has disappeared long ago, and there is another personality hidden in Chu Qingli's body—an amnesia girl who is proficient in mystical arts. Shen Mo thought this was just a ridiculous deal, but he accidentally got involved in a battle for the throne that spanned a thousand years. The five major Xuanmen families, the sleeping strange gods, and the missing royal bloodline, all clues point to an ancient prophecy: when the two moons are in the same sky, the strange gods will come, and the world will become purgatory. The ancestral Yin-Yang jade pendant in Shen Mo's hand is the only key to unlocking the seal of the strange god. Is it to protect the common people, or to dance with the evil god? Shen Mo held the prickly "substitute bride" in his arms and whispered in her ear: "Good boy, stop pretending, I know you can hear me."
