After a mysterious illness takes his mother's life, Han Chun, the second prince of the Heavenly Demon Sect, finds himself cast out into one of the most secluded clans. As an unlikely heir to the throne, he now dedicates himself entirely to figuring out the cause of his mother's untimely death.

Unfortunately, in the Bubu Clan where he now resides, it is difficult to maintain focus when survival takes precedence. Demonic beasts roam the outskirts, and bandits loot at will.

As if by divine providence, Han Chun stumbles upon a strange scroll that contains a long-forgotten martial skill.
