The Tech Guy’s Transmigration

The Tech Guy’s Transmigration

Rodney, an engineering geek, is transmigrated into the body of a minor royal saddled with a destitute fief, crushing debts, and three exiled ex-wives. He applies his modern technical knowledge to rebuild the wasteland territory from the ground up, introducing gunpowder, firearms, smelting, and other innovations to drive off bandits and restore prosperity. One man's engineering expertise becomes the unlikely engine of an entire civilization's revival.
