Great Ming: Sister-in-Law, Please Behave. I Only Want to Farm

You transmigrate into the Ming Dynasty as the good-for-nothing Prince of Liao, and from the start face a poisoned cup sent by the Jianwen Emperor as part of his campaign to strip the princes of their fiefs. Luckily, your widowed imperial sister-in-law secretly sends you a hundred thousand taels of silver to keep you alive. Think this prince is going to scrape by? I turn around and open the industrial technology tree: primitive steelmaking, volley-fire tactics, and steam-powered ironclads sweep all before them. When the imperial court's half-million-strong army lays siege, I roll out the dynamite cannon and tell the world: truth is found only within the range of artillery!
