The soul of a modern society animal takes the form of Zhu Ju, a fourteen-year-old boy from an aristocratic family. His parents were killed and he was expelled from the Zhu family by his eldest brother. He went to Leping with his sister to observe mourning, holding the ancestral body-training method "Thirteen Horizontal Exercises" in hand, and sitting in the pharmacy and tree farm of the house. He polished his body in a remote county and sought a way out step by step in the undercurrents of the rivers and lakes.
