The story takes place in the modern Chinese city "Cloud City". On the surface, it is prosperous in science and technology, but in fact, it is undercurrent. Since the "Heaven Secret" was shattered thousands of years ago, the boundaries between Yin and Yang have become blurred, and metaphysical systems such as Maoshan Taoism, Wu Nuo secrets, and Gu magic have been passed down in the dark. The police station has a mysterious "Special Case Investigation Division" that specializes in handling supernatural murders. The protagonist, Lin Mo, is a forensic doctor and the 63rd generation descendant of Maoshan Zhengdao. He masters Taoist techniques such as the 'Sky Eye' and the 'Five Thunder Curse'. However, he is bound by modern scientific thinking and can only look for traces of metaphysics on the autopsy table. World rules: The recovery of spiritual energy is carried out quietly, but it is covered up by the official; Wu Nuo priests can summon the afterimages of ancient gods, Gu magic can control biological genes, and Maoshan magic can spy on cause and effect. Three main lines are intertwined: scientific reasoning, metaphysical detection, and secret war between forces. The background of the era is 2030. Yuncheng has just experienced a major earthquake, and the ground veins are disordered, causing various supernatural events to occur frequently.
