This is an era abandoned by the Heavenly Dao, and he is a harbinger of disaster despised by all. When the immortal sects send him to the Executioner's Terrace, the Demon Lord he once swore to hunt smashes through the mountain gate, staining the long stone steps with blood. He smiles at him. “They don't want you, but I do. If the immortal path has no place for you, then come with me and become a demon. I'll overturn the Heavenly Dao for you.”
In the “Era of the Fallen Dao,” when the path to ascension has been severed and resources have run dry, Ling Wuchen bears the ill-omened Calamity Divine Vein and struggles to survive among the immortal sects. Mo Yuan, the exiled crown prince of the demon realm who bears the Primordial Chaos Demon Heart, is his destined nemesis. But a “spiritual corruption” crisis threatening the world's survival forces these two outcast souls into an alliance. From wary enemies, they become each other's only cure and salvation. When an ancient conspiracy is unveiled and the truth of the Heavenly Dao exposed, one commands calamity while the other wields chaos. They vow to carve out an entirely new path to the heavens in this crumbling era, for all living beings and for themselves.
