Qin Xiaoxiao was accidentally reborn to the age of 22 through "installment payment" and became an ordinary traffic policeman in Lanjiang City. In order to repay the "huge debt" of 100,000 merits from the underworld, she bound the merit system and formed a partnership with Shui Qingqian, a female ghost from an aristocratic family thousands of years ago. From then on, in her ordinary position as a traffic police officer, she repeatedly solved strange cases by relying on her criminal investigation instincts from her previous life, her newly acquired yin and yang eye abilities, and Shui Qingqian's supernatural perception.
