Yan Chixia is the illegitimate son of the Wulong Manor, a renowned martial arts family. Because his mother was of low birth, he suffered years of abuse at the hands of his stepmother, Bai Meizhu. At six, he was locked in a dark, windowless storeroom for ten years. On the brink of despair, he stumbles upon an ancient mirror engraved with the words "Mirror of the Nine Heavens Mysterious Goddess." A mysterious young man reflected in it helps him master the long-lost arts of the Nine Heavens Unified True Scripture and the Nine Heavens Sword Inquiry. At sixteen, he breaks through the mirror, escapes his prison, and wanders the martial world. Nearly starving to death in the mountains, he is rescued by a band of outlaws from Wufeng Mountain. In this stronghold where strength is everything, Yan Chixia starts out as a servant. Armed with the peerless martial arts foundation he gained from the mirror, he shines in his first battle and gradually earns the respect of his companions. Yet turmoil still grips the martial world, and the shadows of Wulong Manor's past and clues to old acquaintances from the Nangong family continue to haunt him. From a worthless wretch trampled by all to a rising star among the outlaws, Yan Chixia wields the Mysterious Goddess's legacy and sets out on a path of revenge and martial enlightenment.
