Lin Yuan, the first-generation mender of heaven's fate, carries the spirit fox A Yao, the mountain-guarding divine beast Dun Dun, and his natal sword spirit Xuan Shuang. After suffering tragic defeats through eight missions, he initiates his ninth and final journey, shuttling across twelve parallel worlds to fight the fortune-plundering villain organization "Fate-Stealing Bureau" and overturn the doomed fates of the original chosen ones betrayed by destiny. Centered on the core theme that "obsessions find closure and fate is mended," the series blends high-octane satisfaction with deep companion bonds and fateful redemption.
