Modern forensic doctor Song Qingzhao accidentally traveled to the Qingli period of the Dasheng Dynasty, and his soul passed through the daughter of a woman who was dismissed from her post and sentenced to punishment, and the lowest scribe in the punishment department, "Song Zhao". Relying on her knowledge of modern forensic science and rigorous logic, she started by examining unknown corpses and cracking the "will-o'-the-wisp" case, and gradually broke the secular shackles of "women are not allowed to be tortured". During the investigation process, she was involved in a series of major cases such as imperial examination fraud, corruption of imperial merchants, and palace secrets. She supported each other with the upright censor Bao Yanzhi. The full text is based on the main line of "post-mortem analysis - counterattack in the workplace - institutional reform". Each case is related to historical facts (such as the Qingli New Deal, tea and salt law reform), and the highlights focus on "professional crushing prejudice", "smart solving of unresolved cases and slaps in the face" and "women's breakthrough in the workplace".
