Review Detail of Niko91 in King of German Mercenaries

Ok i don't even know were to start, the idea has some potential but you kinda ruined it with bad writhing , and an mc that is dumer than a rock .He was kill in a street fight and now he's rushing to war, were if you are lucky you might survive he uses almost no knowledge from the future , why is it so hard to have an mc with a brain.
