Betrayed by his Master after achieving Core Formation and forging his Golden Core, Bai Langtian loses everything—his cultivation base ripped away, his body cast into an abyss teeming with demonic beasts. Against impossible odds, he survives the fall and encounters Shangguan Yue Ling, a senior sister who endured the same treachery a decade prior. Abandoned in this demon-infested valley, she discovered an unconventional path to power: consuming the corrupted essence of the beasts surrounding them. Yue Ling unveils the forbidden art of Demonic Cultivation, offering Langtian a chance at restoration. To rebuild his shattered strength and exact vengeance upon his betrayer, he must undertake a perilous journey—devouring the flesh and essence of ten thousand demonic beasts, transforming suffering into unyielding power.
