Song Wanwan, a modern funeral director, transmigrates into the body of a sacrificial bride sent to bring good fortune to Bianjing's richest man. On their wedding night, her “frail” husband, Gu Wenxuan, sacrifices her with his own hands. As she teeters on the brink of death, she binds herself to The Rules for Surviving the Weird. Then she discovers that her husband is the Lord of the Abyss, ruler of all the ghosts and monsters. He grips her waist and pins her against the coffin, laughing softly: “Since you've seen through me, my lady, why not stay with me for all eternity?” From then on, she's dragged into his abyss, yet becomes his one and only weakness and salvation.
