In ancient times, the Yellow Emperor fought against Chiyou, and Chiyou was helped by four ferocious beasts. The Yellow Emperor was defeated for a time, and the Sky Fox came to his aid. Later Huang Di won and Chi You was defeated. Only the remaining souls of the four ferocious beasts were left, and the sky fox also died. Tianhu left a prophecy: Tianhu will come to the world again, and the ferocious beast will also wake up. A line of traditional Chinese medicine practitioners in the Yellow Emperor's camp inherited the witchcraft from Chi You, and some of their descendants studied it. Later, they had different ideas from the doctors and left the Miao territory. Thousands of years later, the medical lineage migrated to the northeast, and the population declined. At the same time, there is more than one Sky Fox coming into the world! Could it be that the ferocious beast will also wake up? As the last descendant of a line of doctors, where should I go? Where are the healers who inherited the witchcraft heritage now? What secrets lie in the forests of Changbai Mountain? Will the demon clan and human cultivators join forces again? Below, I will tell you my story.
