The transmigrated youth Lin Yang awakens the Demonic Cultivation God System, relying on various absurd operations to accumulate evil energy values and redeem top-tier cultivation techniques and magical artifacts. Inside the academy, he plays all sorts of creative tricks, modifying a stink tofu electroshock rifle, thrashing opponents in the arena with bizarre spear techniques, and subduing demonic cultivators at the crematorium. In the secret realm battle, relying on lifespan-burning techniques and omnipotent self-healing, he goes head-to-head with fierce beast kings. In the city's martial arts tournament, Lin Yang maxes out earth-grade martial skills, pushing aside all prodigies through underhanded tricks and hilarious stunts. The secret realm grand exam is even more unhinged: using steel rolls as talismans, inventing bizarre elixirs, and blocking bridges to rob examinees, he fights the geniuses of the entire province single-handedly.
