It tells the story of forensic doctor Lin Mo who returns to his hometown due to the unsolved case of the mysterious death of his parents ten years ago. When he stepped into the courtyard covered with mildew, strange phenomena followed one after another: crying in the middle of the night, a black pottery bowl that automatically shifted, "Su Xiulian" written in blood on the wall, and a female ghost in a cheongsam appearing in the mirror. As the investigation deepened, he discovered that the death of his parents was related to the "Corpse Array" underground in the old house, and the copper key left by his mother could actually open the corpse of Blue Mandala growing in the freezer of the morgue. When he found a bronze tripod inscribed with "Guihai Blood Sacrifice" in the basement, the sealed family curse suddenly awakened - it turned out that his grandmother was the only survivor of the disappearance of a village in western Hunan in 1995, and a "pottery urn of resentful souls" made from human blood sacrifice was suppressed under the foundation of the old house. Lin Mo must crack the forbidden spell of the "Ling Fei Sutra" before midnight on the Ghost Festival, otherwise he will be refined into a new sacrifice together with his parents' souls. In the collision between forensic rationality and metaphysical curses, he used a scalpel to cut open the spirit body and deciphered the runes with the logic of the autopsy report. Finally, at the ancient well at the junction of Yin and Yang, he faced the resentful spirit that took the form of his mother and revealed the cruel truth that "Su Xiulian" was actually a Gu master who was sacrificed a hundred years ago, and that she was the reincarnation container of the blood sacrifice.
