In a world where portals to monster-filled dimensions have emerged, Sung Jin-Woo stands out as the weakest hunter among mankind. Dubbed the "World's Weakest Hunter," Jin-Woo's contributions to raids are limited to mere survival. However, faced with mounting financial pressures, including his mother's hospital bills and his sister's tuition, Jin-Woo has no choice but to continue risking his life. When an opportunity for a bigger payout arises, he seizes it, only to find himself face-to-face with an overwhelmingly powerful being. With the party leader injured and the healer incapacitated, Jin-Woo must find a way to lead them to safety. Miraculously surviving the harrowing encounter, Jin-Woo discovers that he has gained access to a mysterious system visible only to him. This interface promises to grant him the power he has long dreamed of, but at a cost. As Jin-Woo embarks on a journey to uncover the secrets behind his newfound abilities and the dungeons that spawned them, he must navigate the treacherous world of hunters and guilds. With each level gained through the system, Jin-Woo grows stronger, transforming from the weakest hunter to a formidable force. However, as he delves deeper into the mysteries surrounding the gates and his own powers, Jin-Woo realizes that the price of his strength may be higher than he ever imagined.
