Negative Reversal System: Losing Lifespan = Gaining Lifespan. He Trains, He Wins, He Becomes #1

A "Negative Reversal System" turns every curse into a blessing — losing lifespan becomes gaining lifespan, deadly poison refines the ultimate Dao foundation, painful cultivation becomes pure pleasure, and even Heaven's punishment turns into divine blessings. The laws of cultivation no longer apply to him. Ye Fan was born with low-grade spirit roots. After a hundred years of hard work, he still couldn't even reach the Foundation Building stage. Resigned to a quiet retirement, he planned to find a wife and live out his remaining years in peace. But fate had other plans. Kidnapped by a stunning demoness from the Heavenly Demon Sect and forced to cultivate a forbidden art that drains his lifespan with every session, Ye Fan should have been doomed. Then his system awakened. 【Negative Reversal System】 Every drawback becomes an advantage. Every forbidden technique turns into a blessing. Every punishment from the heavens becomes a reward. Now, losing lifespan increases his lifespan. Poison strengthens his foundation. Excruciating pain feels like euphoria. And instead of divine punishment, the heavens bless him daily. While others weaken from forbidden arts, Ye Fan only grows stronger — so fast that even Immortal Lords are left stunned: "How are you increasing your talent every time you break through?!" This is the story of a cautious schemer who uses a broken system to turn forbidden paths into the ultimate shortcut to invincibility.
