Based on the ancient "Jedi Tiantong" as the background - after the defeat of the Wu clan, the remnant soul of the leader Chi You split into nine paths, attached to nine "ground nodes" such as the Yellow River, Qinling Mountains, and the southwest Miao border, and transformed into the "Hebo", "Mandrill", "Gu God" and so on in folklore, feeding on human souls to maintain its existence.
