Is Hell Empty? All the Demons Are Here with Me!

[Class Change + Demon Summoning + System + Succubus + Leveling] Hell is empty, and demons are walking the earth. More accurately, Lin Jiu has contracted every last one of them! On the day of the class-change ceremony, the school’s most celebrated student, Lin Jiu, awakens as an F-rank Summoner. The worst talent paired with the most useless class. Lin Jiu says, “I don’t care what class I get, as long as I can make money.” But when he learns that F-rank Summoners can’t enter dungeons at all, and sees his future income disappear, the usually unflappable Lin Jiu falls apart. Then he accidentally binds himself to a System, and his class mutates into a unique, special class: Demon Summoner! At his first summon, the heavens and earth change color. An S-rank succubus descends, her overwhelming presence knocking everyone unconscious! From then on, he has a succubus sidekick and a human-shaped body pillow. With each summon, Lin Jiu contracts more and more demons. He’s practically an army all by himself. Class changers watching Lin Jiu solo the hardest dungeon: “You call that F-rank?” The career prodigies defeated by Lin Jiu: “I thought Summoners were the weakest! How is he pinning me to the ground?” Looking at the nearly deserted demon realm, the Demon King sighs wistfully: “You’re about to empty my whole home. How about contracting me, too?” Later, Lin Jiu and his demon army cut through every opponent, leaving all demons bowing in submission wherever they go.
