Main story: Su Qingwu, a top modern forensic pathologist, accidentally transmigrates into the body of a bullied orphan girl at a Taoist temple in ancient times. From the start, she faces a desperate predicament: she has been framed as an “ill-omened person” and is about to be burned alive. With her extraordinary modern forensic expertise, she examines a corpse before a crowd, identifies the real culprit, clears her name, and shocks the land. From then on, she begins her journey through the ancient world, “speaking for the dead and fighting for the living.”
Using the Taoist temple as her base, she cracks one strange case after another, from “ghosts knocking at the door” to “walking corpses.” With a scalpel and hard evidence, she smashes every superstition, only to become entangled in even stranger events involving genuine sorcery and restless spirits. Along the way, she meets Xie Buyan, a blind musician whose identity is shrouded in mystery. Though sightless, he can “see” the unclean things invisible to ordinary people. One believes in science, the other possesses supernatural abilities. From their initial wariness to their later partnership in investigating the unknown, the two become an unbeatable crime-solving duo.
