Comments of chapter undefined of I am a Problematic Dungeon Master

..Are you kidding me? an army of sadistic, overpowered fanatics , at least 45.000 vs 800 elves and dwarves, and most of those were non-combatants of children, elders and women. And youre telling me that despite Ein barely have any mana from the dungeon, not only exhausted his mana reserves at the elves kingdom to the point where he fainted. And yet he was able to do all of this AND save the only one that nearly died? Author, why? Tell me why in detail why this makes any sense to you after this big event made them split and exhaust their resources and still come out on top..
