You're Just a Down-and-Out Prince, Is It Really Reasonable to Amass a Million Soldiers?

【Alternate history + dead border city + decisive and ruthless protagonist + unstoppable wish-fulfillment + building a power base】 Lu Chen transmigrates to the Great Jing Dynasty and becomes a down-and-out prince. His fief is barren and surrounded by enemies. From the start, the court cuts off his supplies, and his soldiers mutiny! At this desperate moment, he activates the Prosperous People, Strong Nation System! The more people in his fief, the more points he earns each day. Points can unlock all kinds of military supplies, including guns and cannons... Lu Chen quells the mutiny with a single shot to establish his authority, then angrily executes corrupt officials and says coldly: “When the law becomes a tool for the powerful to oppress the people, I, the prince, will abolish it with my own hands!” He makes his fief prosperous and thriving, while the court’s lands are filled with starving corpses! When the Tatars invade, modern weapons crush them. Then, after great effort, they manage to bring in a few cannons and scoff: “Lu Chen, do you have cannons? Let’s see you survive this time!” Lu Chen sneers. “Sorry, I wouldn’t touch that junk. I’ve got dozens of howitzers!” Two years later, Lu Chen’s tanks roll across the land and planes fill the skies... The officials demand coldly, “You’re a vassal prince. Is it really reasonable to command a million troops?” Lu Chen looks up indifferently. “Why should I explain myself?” The emperor swears at him. “Do you have no respect for the ancestral laws?” Lu Chen answers firmly, “Only the weak follow rules. The strong make them!” From then on, wherever the sun and moon shine, it is all my land! Wherever my armies march, all nations bow and the world submits!
