Lu En transmigrates to another world with a game System, but the only way to level it up is to hunt down Demon Kings. During his demon-hunting journey, Lu En encounters all kinds of people: a mage who can't use magic; a dwarf who loves explosions; an elf prince who has given up on life after someone stole his identity; an obsessed saintess who follows him everywhere; and a skeleton searching for hope in the future.
