Review Detail of emrade in I Can Make Everything Level UP

I understand trying to nerf the power of the MC but when not done right, it just makes the MC look like an idiot. It's like he is allergic to getting stronger. He finds out that when killing monsters in the dungeons, he gains alot of XP, and could easily level up and level up his skills too. Any average MC would at least try to get stronger.. .Grind the heck out of the dungeon but this MC has no motivation to do so. Its so frustrating.
