In the fifteenth year of Yuanqing's reign in the Great Chu Dynasty, Shen Ciyuan, the legitimate daughter of Duke Dingguo, died in a fire. The moment before she died, she finally knew: the real culprit who killed her mother was her stepmother, the one who betrayed her was her fiancé, the third prince, and her loyal personal maid was an spy planted by others from beginning to end.
Reborn as fifteen years old - my mother had just passed away three months ago, my stepmother had not yet entered the house, and everything was still too late.
In this life, she is no longer a gentle and virtuous daughter of the boudoir. The forensic skills she secretly learned from the library of the Imperial Medical Office in her previous life have become her sharpest knife. She performs autopsy, examines bones, and investigates cases to find the murderer. She searches for the truth on the dead and plays chess games among the living.
