In a World Overrun by Demons, I Begin with Infinite Enhancements

Li Zhufeng transmigrates to a world overrun by demons. He discovers that he can strengthen weapons, armor, and cultivation arts without limit. Strengthening weapons and armor: Forge divine weapons from evil spirits, and they’ll slay strange creatures the moment they’re drawn. Strengthening cultivation arts: Turn mundane techniques into divine powers, and suppress hordes of demons with a wave of the hand. Everyone says a terrifying Demon King lurks above the heavens. Li Zhufeng looks up from afar and sighs too: “Yeah, it really is terrifying.” “After all, the best materials for strengthening in this world are all growing on him.”
