Modern forensic doctor Xia Ren accidentally traveled to the Daqian Dynasty and became the nephew of the chief registrar of Dali Temple. Coincidentally, the prime minister's son died mysteriously in a secret room. The government wanted to beat him and framed General Mu's daughter as the blame. Gu Changfeng relied on his modern forensic knowledge to open coffins, conduct autopsies, and restore the methods of committing crimes. He successfully overturned the case and uncovered the real murderer, and became famous in one battle. After that, he relied on his excellent case-solving skills to get involved in political disputes in the court. He worked step by step among the imperial power, the prince, and the aristocratic family, solving strange cases one after another, and gradually uncovered the shocking conspiracy involving rebellion and collaboration with the enemy. As a commoner, he became a key figure in stirring up the situation of the Qian Dynasty.
