Solo Leveling Sung Jin Woo

Started out as a low level E-rank hunter going on dangerous mission to earn enough money for his mother's treatments, and to take care of his little sister. Unfortunately, no matter what he did his levels would never go up for in this world one's rank is set in stone, or so he thought. During dungeon sweep his part came across a secret room that trapped them inside with no way out except to play the rules of the room. As the struggled desperately to figure out the puzzle behind the devilish room the fiendishly looking statues came to life and began to slaughter the party. at the last minute they were able to figure out the enough of the puzzle to open a door but it would only allow a few to escape and Jin was chose to be the one left behind. Some how he was able to survive and as a result gained the ability to increase his stats while still only being an E-ranked hunter. Now he has grown stronger and obtained power allies to summon but not with harsh trials and sacrifice to say the least.
