Under the black soil of the Northeast, the ancient contract of Chumaxian hides mysteries, and the spate of abnormal deaths in modern cities and remote countryside are tearing open the gap between reality and the spiritual world. Funeral parlor forensic doctor Shen Zhiwei has been carrying the inheritance of the Immortal since childhood. He can see the souls of the dead with his left eye and discern the yin energy with his right hand. He wanted to hide the inheritance and become an ordinary forensic doctor. However, when he took over the first "death by spontaneous combustion" case, he discovered that the body of the deceased had strange runes that did not belong to the earthly world.
From unsolved cases in secret rooms in urban high-rises to corpses floating in dry wells in old houses in mountain villages, from the sudden death of Internet celebrity anchors to the sudden deaths of scientific researchers in laboratories, each corpse tells the hidden truth - some people use magic sacrifices to extend their lives, some use spiritual bodies to take revenge, some people are punished by heaven for touching taboos, and there are even family curses that span a century are secretly at work. Chen Yan was forced to awaken the spiritual power of the fox fairy in his body, and joined hands with Lin Lan, the hot-tempered criminal police captain, and Xuan Qing, a veteran Taoist master of onmyoji, to form a special detective team to find answers between the forensic autopsy table and the altar of Chumaxian.
