Mo Yang, the last descendant of the Xuanyuan bloodline, awakened the reincarnation of the Demon Emperor in the Qingyun Sword Sect and became a taboo existence that was punished by both immortals and demons. In order to suppress the rampaging ice dragon soul in her body, the saint Ling Yue of Hanyue Palace was forced to make a deal with the Netherworld Demon Lord, but left half of her soul in the underworld. When the human-sacrifice conspiracy behind the plan to mend the sky emerged, the two discovered that the so-called cracks in the heavens were actually the wounds of a superior civilization harvesting the world. On the day when the broken sword was reforged, Mo Yang tore off the shackles of blood and used the body of the Demon Emperor to hold the Xuanyuan Sword and point it at the sky - "If mending the sky requires eradicating love, then let this hypocritical way of heaven experience another great catastrophe!"
