烛九阴

On snowbound Mount Buzhou, the ancient serpent immortal Zhu Jiuyin lives under a heavenly seal. Nine-year-old orphan A Fei enters the mountain to save his gravely ill mother and becomes Zhu Jiuyin's only disciple. Their bond brings warmth to his long isolation, but A Fei is later killed after becoming caught in a conflict with powerful people. His disciple's death breaks the seal, and Zhu Jiuyin sets out to avenge him.
