I Alone Level-Up

Ten years ago, after the opening of the “Gate” that connected the real world to the monster world, ordinary people in society were given the power to hunt monsters inside the Gates. They are known as “Hunters”. However, not all Hunters are powerful. My name is Sung Jin-Woo, a Hunter of Rank E. I’m someone who has to risk his life in the lowest dungeon, the “weakest in the world”. Having no skills to show, I barely made enough money to fight in low level dungeons… at least until I discovered a secret dungeon with the highest difficulty in a D-level dungeon! Finally, as I was accepting death, I suddenly received a strange power, a quest diary that only I could see, a secret that only I knew to raise my level! If I trained in accordance with my quests and hunted monsters, my level would rise. Going from the weakest Hunter to the strongest S-ranked Hunter!
