A City Falls from the Sky

They are the creators of the new era, the pioneers in rewriting the new order, and the civilized bandits who run rampant in feudal society. Their team of a hundred people can stop an army of millions. They control the lifeblood of the world and they are fearless. Rebirth? Time travel? No! They are a bunch of miserable people who fell from the sky. Soaps and perfumes are already out, and the business they have done is unimaginable. Lay ceramic tiles on city walls, build reinforced concrete fortresses, generate hydroelectric power, wind power, and mine rare resources... With millet and rifles, they used a civilization that was dozens of centuries in advance to wreak havoc in feudal society. Which is faster, your sword or my bullets? Do you want me to let it fly for a while?
