Awakened Negative Reversal System: Losses turn into gains, poison into divine elixirs.

Ye Bufan transmigrated to a cultivation world. As an ordinary rogue cultivator of Zhao Kingdom, he possessed a low-grade Yang Spiritual Root. He diligently cultivated for a hundred years, yet still failed to reach the Foundation Establishment Realm and grew old in vain. With his immortal path seemingly shattered, he merely wished to marry a wife and live out his remaining days in peace. However, fate had other plans. He was abducted by a stunning witch from the Heavenly Demon Sect, forced to become her spirit cauldron and practice harmful demonic arts that drained his lifespan. Trapped in desperation, he had no way to escape. At his darkest hour, the Negative Reversal System awakened! All side effects of cultivation techniques, pills and spells were perfectly reversed into supreme blessings. The Blood Spirit Art that cost ten days of lifespan per practice? It granted him ten extra days instead! The toxic Demonic Foundation Pill that only forged inferior foundations? It became non-toxic and forged a peerless Heavenly Dao foundation! The bone-piercing, slow-cultivating Holy Demon Art felt incredibly pleasant and boosted his cultivation speed immensely. Divination arts that cost lifespan and heavenly tribulations granted him boundless longevity and constant heavenly blessings. The demonic art that degraded aptitude ultimately elevated his physique to an immortal rank.
