At Mao hour, I am seducing souls in the underworld; at You hour, I am giving orders in heaven. Last night I added ten years to a mortal's life in the life book, but this morning it was written in the life and death book that he died on the spot. But when I took away his soul with my own hands, I discovered that it was not just Yangshou that had been erased, but also the destiny that should have been his.
In the Three Realms, the Ming Book records life, and the Life and Death Book records death. It should be even one ten thousandth. Nowadays, the error is getting bigger year by year. More and more people who "should not die" die early, and the essence of their fate disappears. Heaven says this is destiny, and hell says this is reincarnation, but I know that someone is stealing the lives of all living beings in the cracks of the three realms.
During the day, I am Jiang Qi, the coldest seductress in the underworld; at night, I am Si Mingxingjun, whose origin is a mystery in heaven. In order to find out the truth, I can only walk back and forth between the Yin and Yang realms, avoiding the temptations of heaven and hell, while working together with Su Zhiyao, a girl from the Qintian Prison who can see the cracks in fate, to solve the case. But she didn't know yet that the two mysterious people she was tracking were actually the same me.
