When I was eight years old, I was playing in the village during the winter vacation, but I accidentally saw the big horse monkey in my grandma's story. I always thought that the big horse monkey was as scary as the story told, and was an out-and-out monster. But who would have thought that with the appearance of the big horse monkey, people were gradually being killed in the village. When the victims appeared one by one, a secret that had been hidden in the village gradually surfaced.
