Longevity Hacker: When Every Curse Becomes a Blessing

Ye Bufan spent a hundred cautious years as a nameless rogue cultivator in the Zhao Kingdom. Born with a low-grade Yang spiritual root, he once dreamed of stepping onto the immortal path— but after a lifetime of toil, even as an old man, he still couldn't form his Foundation. Just when he decided to give up cultivation, marry a wife, and live out his final years in peace... he was abducted by a stunning witch from the Demonic Sect— and turned into her furnace cauldron! Worse, she forced him to practice a life-draining demonic art that consumed lifespan with every session. Ye Bufan was ready to die... until a voice echoed in his mind: "Negative Effect Reversal System activated." From that moment, every curse became a blessing. Blood Spirit Art: Increases cultivation quickly. Side effect: lose ten days of lifespan per session. → After reversal: gain ten days of lifespan! Demonic Foundation Pill: filled with deadly poison, forms the lowest-grade core. → After reversal: forms the supreme Heavenly Dao Foundation! Soon, the "furnace" became the immortal, and even the witch who captured him stared in disbelief— her cauldron had surpassed her cultivation and turned into a living legend. The Demon Patriarch: "The pain of the Heaven-Devouring Art should break your bones daily— What? You say it feels good? And you're cultivating faster?! Impossible!" The Heavenly Seer: "Each divination shortens your lifespan, yet your longevity keeps rising?! Are you blessed by Heaven itself?" From Foundation Establishment to Ascension, Ye Bufan walked the demonic path backward— a hundred years to immortality, all by hacking the system of fate itself.
