Necronomics

"If you let these necromancers go unchecked, you will one day be overwhelmed by the undead army!" "What undead army, I haven't seen it? These are skeletons specially used for mining. They work in dangerous mines instead of miners." "This is a zombie that generates dangerous chemicals in a factory. Deadly chemicals can't kill dead zombies." "This is the Dread Knights. They are, uh, plowing the fields now. They don't need to eat or rest." "In these days, everyone has guns and artillery, so who still fights with an army of the undead?" When war broke out one day and people saw a massive army of undead armed with muskets and artillery, they were stunned.
