A Million Zombies Invade. Is Raising Ten Million Troops Really Too Much?

[Set in a fictional world, unrelated to reality] [A zombie story, possibly with other elements mixed in] [Mass recruitment, conquest, no saintly heroics. A newbie author whose first ten thousand words usually decide their fate. If it gets picked up for serialization, I’m out of here.] Reincarnated in another world, I’m told as soon as I arrive that the apocalypse is coming! Zombies are everywhere, and danger is constant. Luckily, I have the Red Alert System. As long as I have enough funds, I’ll slaughter anything that comes my way, even the gods! A million zombies invading? I’ll just turn around and raise an army of ten million! It’s a numbers game, right? It’s not like I’m the only one with an army! My brothers-in-arms are endless, while your forces are dwindling by the second! In this battle, the advantage is mine!
