There's a huge plot hole. The level starts at 0 not 1. MC manage to level up to 2 without needing to earn experience at all. He started at level 1 and when he got a class he becomes level 2 instantly. MC says he can level up to 100 by just picking 100 level 1 classes. Bullshit. Even with that level logic is still fine, i would've been reading this if MC doesn't just yap about game mechanics in his monologues that is completely unnecessary to his situation. I've read 10% of the novel yet the novel barely made progress.
