After centuries of relentless effort, the Heavenly Demon finally succeeded in creating a forbidden art—the Reincarnation Art. But before he could perfect it, the heavens declared war upon him. In a battle so fierce it shook both heaven and earth, he was ultimately defeated by the Sword God. Yet, just as the final blow was about to claim his life, he unleashed his forbidden art and escaped into the mortal realm. He awakened in the body of a prince from the Ling family—a once-promising cultivator who had lost his powers to poisoning and was now a hostage of the Feng clan. Branded by the consequences of his forbidden magic, the Heavenly Demon must carve his way back to the Sacred Realm to reclaim his throne and exact his vengeance. This is the tale of an unyielding demon who will stop at nothing.
