Review Detail of Alex1911 in Infinite Mana in the Apocalypse

I don't know how to feel about this story. I like the setting, the writing quality is much better than most fanfic, the update speed is awesome. But the MC is absolutely infuriating, it's like the author purposely make a MC with negative IQ just to tick off reader for fun. After clearing the first dungeon, he sell all the cores for money without strengthen himself. He has infinite mana yet he sell the summoning skill book( and some other skill books as well).... Fck, why the hell does he even sell skill books? Just learn everything and only sell the cores he doesn't need for money. He kept clearing dungeons multiple time and selling drops in bulk, yet he asked how did people discovered him..... Does the fcker think everyone has his IQ? On the bright side, he did learn from his mistake, but those are common sense, even a "normal" ten years old is suppose to know that. Thing might get better latter but currently I just can't stand this MC retardness.
