The female body has a special constitution and is born with a "vaginal bone". She can trigger the "death replay" ability by touching the corpse within seven days after death, and can see the memory fragments of the last seven days and nights of the deceased's life. After she was forced to marry the prince who died suddenly, she used this ability to redress the injustices of the concubines, eunuchs, and maids in the palace who died in vain, and gradually uncovered the bloody secrets of generations of the palace. Every autopsy is a dangerous journey to empathize with the dead - the longer she looks at it, the easier it is to be eroded by the resentment of the deceased. Once she does not stay awake for more than seven days, she will be permanently lost in the memory of the deceased and become a living corpse.
