Ten years ago, humanity stood on the brink of destruction when mysterious gates—portals to other dimensions filled with terrifying monsters impervious to conventional weapons—began appearing worldwide. Alongside these gates, some humans gained extraordinary abilities, becoming hunters tasked with entering the gates and clearing the deadly dungeons within. To survive and thrive, many hunters formed guilds.
Among them is Sung Jin-Woo, an E-rank hunter infamous for being the weakest of them all. During what should have been a routine raid in a supposedly safe dungeon, Jin-Woo and his party discover a strange tunnel leading to a deeper, more dangerous area. Drawn by the hope of treasure, they push forward—only to face unspeakable horrors. Against all odds, Jin-Woo survives the ordeal and wakes up to find a mysterious system interface that only he can see. This system offers him the power he’s always dreamed of—but at a cost he could never have imagined. Based on Chu-Gong's popular web novel and webtoon.
