The heroine is not a "healer" in the traditional sense, but a "corpse reader". She can reconstruct the complete experience of the deceased from the bones, organs, and residual drugs of the corpse-including the palace secrets such as being poisoned, beaten, and long-term mental torture. The concubines in the harem killed each other, but no one dared to report it to the official, so the heroine, an "outsider", became the only channel that could speak for the dead. The core of the story is not to cure the disease, but to "examine the body - solve the case - avenge the dead". The palace fight is cut from the perspective of a widower, and each corpse is a unit of the case.
