Jin-Woo is known as the “World’s Weakest Hunter” and struggles to survive in low-level dungeons. However, during a disastrous raid, he and his party get trapped in a deadly Double Dungeon. Left for dead, he receives a mysterious “System”, granting him the unique ability to level up—something unheard of among hunters.

As Jin-Woo grows stronger, he embarks on a journey to uncover the secrets of the dungeons, the System, and the origins of his new power. He rises from being the weakest hunter to the strongest, eventually facing monarchs and rulers, godlike beings that influence the world’s fate.
