Solo leveling S1 & S2

They say whatever doesn't kill you makes you stronger, but that's not the case for the world's weakest hunter, Sung Jinwoo. After being brutally slaughtered by monsters in a high-ranking double dungeon, Jinwoo comes back with the System—a mysterious program only he can see—that's leveling him up in every way. From the weakest hunter of all mankind to the legendary Shadow Monarch, this is his story of leveling up solo.
