Su Wanzhao, a handyman disciple of the Xuanqing sect of the Great Chu, died unjustly because his parents were falsely accused by the sect, and he was reduced to a slave at the bottom and was bullied. Once she was in danger in the back mountain, she picked up the "Underworld Mission Book" bound to her soul and became the "Soul Seducer". She had to complete tasks such as redressing the grievances of the wronged souls, transforming obsessions, and unlocking functions such as the Yin and Yang Eyes and the Time Acceleration Training Room. As the mission progressed, she not only improved her strength, but also discovered that her parents' grievances were related to the head of the sect. At the same time, she went from supervising to falling in love with Gu Mingyuan, the head of the Underworld Soul Crossing Division. The two teamed up to expose the crime of embezzling disaster relief funds and persecuting disciples. The heroine eventually became the head of the Xuanqing sect and the leader of the Yin and Yang envoys of the underworld, achieving a counterattack from being a handyman to controlling Yin and Yang.
