Demonic Cultivation: My Side Effects Become Ultimate Power

Transmigrated into a ruthless world of demonic cultivation, Li Yan becomes a disposable pill slave—force-fed parasitic worms by a twisted Daoist. Death seems certain until he awakens a reality-breaking system: every deadly side effect transforms into overwhelming power. Poison that should kill? Now it's immortal strength. Curses meant to cripple? They become divine abilities. In a realm where demonic cultivators sacrifice anything for power, Li Yan's enemies unwittingly fuel his rise with their own twisted techniques.
