2 Solo leveling/I alone level up

Ten years ago, "the Gate" in a form of a dungeon appeared and connected the real world with a realm of magic and monsters. To combat these vile beasts, ordinary people received superhuman powers and became known as "Hunters."

Twenty years old Sung Jin-Woo is one such Hunter, but he is known as the "World's Weakest," owing to his pathetic power compared to even a measly E-Rank since he was like an ordinary human but just a bit of strength. Still, he hunts monsters tirelessly in low-rank gates/dungeons just to pay his mother's medical bills.

However, this miserable lifestyle changes when Jin-Woo, believing himself to be the only one left to die in a mission gone terribly wrong—awakens in a hospital three days later to find a mysterious screen floating in front of him. This "Quest Log" demands that Jin-Woo completes an unrealistic and intense training program or face an appropriate penalty. Initially reluctant to comply because of the quest's rigor, Jin-Woo soon finds that it may just transform him into one of the world's most fearsome and strongest S rank Hunter.
