Back in the Great Song as a Capitalist

I transmigrate to the Great Song by accident, only to find it struck by drought. First things first, I make money. Once I’ve earned enough, I start developing gunpowder, and before long, guns and cannons appear out of nowhere. I can’t ride a horse, so I invent a car. Is that really so outrageous? The car is too slow, so I invent a plane. Is that so outrageous, either? Keep mouthing off and I’ll drop an atomic bomb on you. We might as well all go down together.
