Republican Era: You’re a County Magistrate With a Million-Man Army

[Infrastructure fanatic + warlord rivalries + all-out troop building] He transmigrates to a hopelessly rotten Republic of China and becomes a county magistrate in a town where the officials and bandits are all in cahoots. Driven into a corner, Lin Rui binds to the System for a Tycoon in Troubled Times and becomes a ruthless war god from the start! He summons fifty death soldiers armed with Thompson submachine guns, slaughters the Black Tiger Gang, and executes its tyrannical boss! He crushes a riot at the police station and raids the four great clans within seven days, taking total control of the county government! He goes all out on infrastructure. Massive cement and steel plants roar through the night, their output the highest in the nation. He issues bonds to raise financing, builds the world's tallest skyscraper, and constructs a massive deepwater naval harbor! He recruits a million refugees and forms an invincible garrison battalion, with heavy artillery crushing all opposition. While the surrounding warlords are still killing each other over a few old rifles, Lin Rui has already built an invincible industrial empire! The warlords are dumbfounded: “You're just a little county magistrate. How the hell did you build an army of a million?!”
