As all races invade, the Heavenly Dao manifests. Su Rui transmigrates into this world and, from the start, awakens the special Beast Tamer class. But because his family is poor, everyone laughs at him: contracts cost an endless fortune. Just as everyone is waiting to see him make a fool of himself, the System arrives in the nick of time, and he summons an ancient overlord! While everyone else struggles to clear beginner dungeons in a party, he breezes through them alone with one beast. While everyone else fights over a single piece of beginner gear, he casually sells it as junk. Just when everyone thinks he peaked on his debut, he turns around and brings out Belial... He contracts every giant beast in the world all by himself!
