Ye Bufan traveled through the world of cultivating immortals and became a casual cultivator in the Kingdom of Zhao. He had a low-grade Yang spirit root. He practiced hard for hundreds of years and still had no foundation in his old age. He wanted to get married and spend the rest of his life, but he was abducted by the beautiful witch from the Heavenly Demon Sect and forced to practice life-reducing magic skills. In a desperate situation, he awakens the negative reversal system, which can turn negative side effects of exercises, elixirs, etc. Into positive. Since then, he has taken advantage of the "side effects" of magic skills to rise against the odds, increase his lifespan, improve his cultivation, build top Taoist foundations, and defeat powerful enemies from all walks of life. He has gradually grown from a down-and-out old cultivator to the pinnacle of the world of immortality, deducing a sinister and steady counterattack legend.
