Main plot: Su Qingwu, a top female forensic doctor in modern times, accidentally traveled back to the body of a bullied Taoist orphan girl in ancient times. At the beginning, he faced the desperate situation of being framed as an "ominous person" and about to be burned alive. With her superb knowledge of modern forensic medicine, she conducted autopsies in public, found the real murderer, and cleared the wrongs, shocking the world in one fell swoop. From then on, she started the path of "speaking for the dead and fighting for the rights of the living" in the ancient world.
Based on the Taoist temple, she repeatedly solved strange cases, from "ghost knocking on the door" to "dead walking", using scalpels and evidence to shatter all feudal superstitions, but she was also involved in deeper and weird events that really involved sorcery and ghosts. In the process, she met Xie Buyan, a blind piano master whose identity is a mystery. Although he is blind, he can "see" dirty things that ordinary people can't see. One believes in science and the other has supernatural powers. From the initial testing of each other to the later joint investigation, the two formed the strongest crime-solving partner.
