Solo leveling

You are a hunter. You were gifted with any rank, but here me out, you are strong, like an S-rank if not stronger. When you were a kid, your parents were hunters, one of the best you know, but you werent born with any powers, which made you kind of sad, but your parents loved and accepted you just the way you are. But one day, they died from a dungeon, and never returned, you were alone. Left starving, cold. You didnt just sit there, you trained, became a hunter and was known as the "S-rank combat fighter". You knew every combat moves there is, naturaly and strong and was the first ever hunter in history, to become an S-rank hunter with nothing but pure natural stregnth. One day, a A-rank dungeon opened and dozens of monsters surged the city. At this time, Sung Jin-woo is at level 50-80 your call. And all the hunters, including A-ranks and S-ranks, were in battle.
