Genius female coroner Li Qiuhan, to inherit her maternal grandfather's legacy, disguises herself as a man to enter the Dali Temple, forced to partner with the "Living Hades" Shaoqing Mo Hanxi. From the ghost-demanding-life case, the opera troupe headless case, the locked-room poisoning case to the imperial examination fraud, border military provisions, and imperial palace secrets, they solve nine bizarre cases step by step, gradually uncovering a major court treason case and overthrowing villains such as Li Chengqi and the Prince Regent. The cold-faced Shaoqing goes from being on guard to being protective and secretly jealous, finally holding the little female coroner in his arms after her identity is exposed. The Emperor bestows a marriage, they have a grand red wedding, and from then on there is an extra table in the autopsy room, with the sunlight just right and long, peaceful years.
