The Great Ming's Mightiest Eunuch

I, Wang Cheng'en, am the last loyal eunuch of the Ming dynasty. Now I’ve returned with the Empire System. Mission: assist Chongzhen and restore the Ming. Rewards: flintlock blueprints, high-yield seeds, and the power to summon great generals. Goal: carve out an empire on which the sun never sets! Wu Sangui? Let him keep guarding Shanhai Pass. The Donglin faction? Send them all to the mines. All I care about are the System’s merit points and His Majesty’s realm. Your Majesty, sit back and relax. I’ll win this realm for you.
