Lin Yuan, an apprentice beast tamer from a humble family, is framed for colluding with demons and driven out of his sect. By chance, he awakens an innate pupil art that lets him communicate with all beasts. He tames a dying Hellwolf and awakens its bloodline, then uses fragments of the Beast-Taming Decree to awaken an ancient dragon soul. In an ancient human city besieged by foreign races, he unleashes a beast tide to slaughter the invaders. At the imperial capital, he uses a young Taotie to cow the assembled ministers. In the end, he learns that he is the reincarnation of the first Beast God.
