When Lü Yang acquires the legendary 【Book of a Hundred Lifetimes】, he discovers a path to resurrection—each death grants him another chance to begin again, retaining treasures, cultivation base, lifespan, and occasionally unlocking dormant talents from previous incarnations. Yet this power comes with a brutal limitation: only finite uses remain. As the Cultivation World descends into turmoil, Lü Yang chooses seclusion within the Demon Sect, intending to cultivate in solitude across countless lifetimes until achieving immortality. But the sect proves devastatingly treacherous, teeming with ruthless prodigies. His first lifetime ends in agony—his Senior Sister's overwhelming assault drains his life force entirely. The second sees him seizing dominance and returning the favor, only to fall to his Senior Brother's lethal ambush. Through the third, fourth, and beyond... After a hundred lifetimes of struggle, Lü Yang emerges transformed: the Primordial Saint Sect's most fearsome Demonic Overlord, a calamity incarnate within the sect's dark halls. "The Demon Sect truly breeds talent. Such honeyed words they speak." "I find myself rather fond of this place."
