I can't understand mc's personality, she changes too often, sometimes he's very daring (when it's causing him problems) other times he's too loose, when he was a little more daring , it might have saved him some trouble...another point that I don't understand, that's why the mc doesn't progress at all without his system, he spent a year at the academy without advancing only a little in his magic cultivation, nor in the level of these spells, he relies completely on his system, suddenly I don't understand what he does all the time in which the other students progress, are their talents so weak? it has no compatibility with black magic? the author does not explain anything, he is just blocking it as long as he does not use his system, which is frustrating
