Kaoshantun, deep in the northeast, is hidden in the folds of the remaining mountains of Changbai Mountain. Buried under the black soil are not only crops, but also secrets that our ancestors dare not tell. Twenty years ago, young Chen Mo fled his hometown with his parents due to a strange "yellow man's house"; twenty years later, an urgent telegram dragged him back - the grandmother who raised him died mysteriously in his old house, and his death was exactly the same as that of his neighbor who had the house.
Returning to Kaoshan Village, Chen Mo found that the village had changed, but nothing seemed to have changed. The sound of hair being combed can be heard every night in the mourning hall of his grandmother, there are strange shadows hidden in the mirror cabinets of the old house, the "ecstasy" in the back mountain always swallows no one when the fog rises, and the old people in the village look at him with indescribable fear.
As he peels off the old things left by his grandmother bit by bit, the curse of Huang Pizi, the taboo of Chumaxian, the "substitute" in the ancient well, the ginseng picker who froze to death in the mountains a hundred years ago... These strange things that have been dusted by time surface one after another. He gradually understood that his escape was not the end, but the beginning of the curse, and he had already been the "sacrifice" chosen by the black earth.
