O Senhor do Mundo Antigo

Engineering graduate Jace crossed into another world, where he became a collateral relative of a feudal lord. Upon arrival, he was immediately forced to select the wives, choose a fiefdom, and repay the debts of three convicted wives. Burdened by debt, surrounded by bandits, and facing a land in ruins, he applied modern industrial knowledge to reshape the order of an agricultural civilization. He introduced gunpowder, advanced smelting techniques, firearms production, perfumery, and even rainmaking, steadily turning the devastated territory around.
