Lin Yu was originally a young man who loved myths and legends, but accidentally traveled to a fantasy world dominated by beast control. Here, humans improve their strength through contracted spiritual beasts. Lin Yu discovered that he had special telepathy and could communicate with any spiritual beast. He also obtained a mysterious ancient illustrated book, which can record, copy and strengthen the skills of spiritual beasts.
With these abilities, Lin Yu successively contracted with powerful mythical beasts such as Qinglong Cub, Fire Phoenix, Xuanwu, etc., And led them to continuously evolve and become stronger. On the road of beast master, Lin Yu experienced various challenges, met his partner Su Li, defeated the powerful enemy Mo Han, and revealed the mystery of his life experience. Eventually, he grew up to be the most powerful beast-controller in the world, guarding the peace of the entire continent.
