Folklore scholar Shen Jingci went to Wuyin Village, an ancient village that was barely visible on the map, to investigate an endangered skill of "returning gods with clay sculptures". However, the last old craftsman he was looking for disappeared mysteriously, leaving only a house full of weird, half-finished clay sculptures. The atmosphere in the village is depressing. The villagers are secretive about a forgotten mountain god. Every household has strange runes carved on the lintel. As the investigation deepened, Shen Jingci discovered that the so-called "returning the gods" was not an offering, but an ancient suppression ritual. Whenever the thick fog lingers in the village, whispers will come from the forgotten shrine deep in the mountain col. The disappearance is just the beginning of this sacrifice. His only clue points to a young man in the village whose identity is a mystery - Cang Shu. He seems to be the only person who knows all the secrets of Kirigakure Village. In this land shrouded in thick fog and taboos, Shen Jingci must uncover the mind-shattering truth behind the shrine before he himself becomes a sacrifice.
