Due to his special fate, the male protagonist was accidentally involved in a series of supernatural events that could not be explained by conventional principles. The first story at the beginning points directly to the "Big Horse Monkey" often spoken by the elderly in Northeast China. In a realistic painting style with a strong sense of reality, this mysterious creature hidden in the deep mountains and forests is no longer just a bedtime story to scare children, but has turned into a real crisis. Facing the unknown in the mountains, how will the protagonist respond? A journey that combines folk taboos and exploration begins.
