The white lion cub Lingyao is born. Despite being troubled by an ancient prophecy, his father, Chilie, accepts him. His jealous uncle, Chixiao, pretends to pledge allegiance to the family, then plots to kill Chilie at the Sunken Mirror Pond, seizes the lion's den, takes the family hostage, and hunts Lingyao down. Lingyao escapes into the wilderness, where he meets Qingli and Liqiu before traveling far to Snowridge Lion Valley to train under a master. Two years later, he returns to rescue his family and defeats Chixiao in a decisive battle at Broken Wind Cliff. But Chixiao's son, Moliao, secretly harbors a grudge and plots his revenge, eventually kidnapping Lingyao's son, Lingyi. Keeping his cool, Lingyao devises a rescue plan and defeats Moliao on a rainy night. Yet he chooses to abandon killing, establishes a covenant at the boundary stone, and breaks the cycle of hatred, restoring peace to the grasslands.
