Ch 29 bc main saved the school and an important lady of a merchant group, she give him a black card exclusive and main could get exclusive medicine with the card but the hospital is having trouble finding the medicine Ch 24 main unlocked a new hero character who is a scientist of engineering Ch 21 recap, main won the competition but something happened in the real world. Mercenaries invaded the school to assassinate the rich lady due to some political strife within her family branches of business. The students were in the crosshairs and main saved his classmates and showed he is powerful than his usual lvl 3 self. Main lvled up his hero card more Ch 14 a rich lady that is sponsoring the competition is looking for potential students who would be a good investment to raise and lvl up to join in her company of fighting in dungeons. Her eye is on main as curious of him unable to lvl up past 3 but is able to do the impossible Ch 7 main needs to make money to help his parents. He managed to pay the hospital bills but his father still needs longer treatment. His college has a competition to fight a dungeon and defeated the elite boss. By forming teams, and even killing other teams to get points, whoever kills the boss wins a lot of money. Ch 4 recap, so far ppl can lvl up and gain xp from defeating monsters coming from portals. Main was always at lvl 3 and no improvements. But when main protected his family from an elite monster, main lvled up and unlocked something inside. His internal system had a feature where he can unlock hero-like characters to borrow their strengths. That's why main never lvl up past 3 bc all the exp was going to his internal system to unlock a lvl 10 hero character with unique elemental attributes. It is an expensive system that takes all of mains xp to lvl up but having a hidden card that he can actually use, main will lvl those features and even unlock more characters in his arsenal
