My Immortality Cheat: I Trade Levels for Lifespan

Transmigrated into the frail, dying body of an old spiritual farmer with mere days left to live, Wei Zhong is an easy target. His greedy disciple already plots his murder, eager to claim his meager inheritance and resources. Scorned and weak, death seems inevitable. But Wei Zhong isn't helpless. He wields a hidden, unprecedented ability: the power to downgrade his cultivation realm in exchange for years of precious lifespan! His combat strength doesn't diminish; instead, his forgotten martial arts and unparalleled mastery over low-level spells turn him into an unpredictable, lethal force, capable of slaying far above his apparent level. With renewed vitality and a ruthless cunning, Wei Zhong must navigate a world teeming with powerful cultivators, hidden auctions, and dangerous secrets. As mighty sects and rival families underestimate the 'dying' old man, can he truly forge an infinite path to power, or will his unique cheat be exposed, attracting a deadly hunt for his immortality secret?
