At the end of the Dayou Dynasty, the imperial power fell and demons lurked in the courts and streets. The four paths of Confucianism, Buddhism, Taoism and witchcraft coexist, but the path of cultivation often leads to madness and mutation.
Gu Shen, also known as Wuyou, appears to be an apprentice at the lowest level of the Criminal Department in Beijing, but in fact he is a time traveler from the modern era, possessing the professional knowledge of forensic medicine from his past life. He unexpectedly acquired the ability of [Tongyou Corpse Language], which allows him to extract the last emotional fragments and image afterimages of the deceased by touching the corpse, but he is also cursed - every time he uses the ability, his life will be consumed. Only by solving strange cases and accumulating merit can he continue to live.
In order to survive, Gu Shen was forced to get involved in a series of strange demon murder cases. He used silver needles to detect poisons, examine bones and identify injuries, and used modern forensic techniques to uncover the "magic stories" in the eyes of the ancients; he used the power of corpse speech to peel off cocoons and uncover the shocking conspiracy hidden in the shadow of the dynasty.
When an autopsy knife encounters a strange corpse whisper, when modern science collides with weird legends, a story about immortality, betrayal and revenge begins.
