Shake It, The Crazy Dragon Is Out

Legendary figure Chen Zigong has been dormant in Dragon Prison for ten years. On the eve of his release, he is entrusted by his cellmate, Big Brother Tang, to protect his sister, Tang Xiaoyu. To conceal his identity, he disguises himself as a janitor at the Tang family martial arts academy, only to face an invasion led by Zhao Qingcheng who forces Tang Xiaoyu to sign a seven-day life-or-death contract! In secret, Chen Zigong mentors an old groundskeeper into a world-class fighter. On the seventh day, at the arena, the old servant fights valiantly against the heavens but still falls short of the God of War summoned by the Zhao family. At the critical moment, Chen Zigong tears away his disguise, slays the God of War with a single palm strike, and turns the seven-day pact into the legendary prologue of his return to the peak!
