While hiding his identity and uniting with people of the An Kingdom to fight against the oppression of the Lian Kingdom and the curse of beast transformation, he exposes the truth that Ye Huan maintains the light‑energy pillar by absorbing human lives. Finally, together with his companions, he destroys the root of evil, breaks down prejudices, achieves coexistence between humans and beast‑men, and ushers in true light.
