When the Hero Is a Smart Paradox Player

"Great heroes, we summon you from another world to defeat the Demon King and the invaders, to save us from misery. Come forth! Five heroes!" But these poor natives don't know that among the five heroes, one is even more evil than the Demon King! Who is he? He is Zhang Kan, a staunch advocate of medieval medicine, a map painter, a cannery owner, the most loyal lackey of the Ming Dynasty, a friend of Rome, a man who punches the Pope and kicks the Fallen Empire, who sees lives as numbers and borders as nothing—a Paradox player! A story of a Paradox player transmigrating into a hero. This is a Western fantasy world where historical armies, figures, and technologies from different eras of OTL fall from the sky. The protagonist's teammates include Rommel, a chicken farmer, Napoleon, and many other historical big shots, heroes and scoundrels from Tongliao, spanning multiple famous Paradox timelines like TNO and KR. A crazy adventure story of a Paradox fanatic. See how he saves the other world by training Linde Van, strategically marrying off daughters, and building an endless toll road economy! (A meme novel, don't take it too seriously, the protagonist is crazy.)
