The last descendant of the dragon race, Ye Long, is reborn with bitter hatred, abandoning a female body to choose a male body. Xu Lang also carries memories of his past life, pretending to court her, but Ye Long plays along with his game. During the covenant bonding, she uses a secret dragon technique to rewrite it into a same-sex master-servant contract, making him a slave. Within seven days, she feigns weakness; the dragon scales and dragon horns she gifts him both turn into poisons, rotting his bones and causing infertility, while further deepening the contract and causing black veins to appear on Xu Lang's body. On the night of transformation, Xu Lang actually offers her to He Tianfang to pay off a debt. Ye Long appears with the imposing aura of a war god, shattering his dream of control, publicly activating the contract, and forcing Xu Lang to kneel. The abuser of the past life now sees their positions reversed.
