Yun Yehe was once the most dazzling Taoist genius of Jiuxiao Sect, but his Taoist heart was cut out by his best friend Lu Ciqing with his own hands, and his spiritual veins were taken away, and he was discarded like a pair of worn shoes. After five years of exile, he used his broken body to swallow demon blood and refine demon bones, and finally used a fate-defying method to reforge his Taoist heart. When that familiar figure knelt under the sect's altar again, Yun Yehe stepped on the clouds and returned with a blood sword in his hand, splitting the sky with one sword and shattering the thousand-year sect rules. Everyone then knew that the betrayer was not ruthless, but used his body as a bait to block the ninth heavenly catastrophe for him. Now he is back, not for revenge, but to personally return the stolen Taoist heart to the person who is still guarding the star lamp for him.
