Shen Lingshuo, Sihe, and Xie Qingxuan are the last orthodox descendants of the Nuowu, Wuzhu, and Yinyang lines respectively. On the surface, the three of them are ordinary folklore researchers, museum librarians and history teachers. They firmly believe in science and never mention ghosts and gods.
Until strange things happened frequently in urban and rural areas: evil in ancient houses, strange shadows in deserted villages, evil at construction sites, and resentment in ancient towns... All incidents pointed to the remnants of a thousand-year-old evil that had been forgotten.
In order to protect the safety of one party, the three were forced to join forces. Nuo dance suppresses evil spirits, shamanic sounds penetrate the secluded world, and Xuanmen cuts off yin and yang. Ancient methods are used to break the mystery, and scientific explanations are used to conceal the truth. There is no love or ambiguity in the whole process, only tacit understanding and sharing life and death.
While they were investigating clues, solving secret cases, and breaking formations, they were fighting against the man-made black hands behind the evil, and uncovered the ultimate secret guarded by the Three Meridians for thousands of years - there are no ghosts in the world, only the human heart hides evil and obsession turns evil into evil.
Purpose: scientific cloak, hard-core evil suppression, unit case grabbing, and constant reversal of the main plot
