A Bandit Queen Tried to Force Me into Marriage, So I Had to Unite the World!

[Live-in son-in-law | Female bandit chief | Multiple heroines | Plagiarist | Technological superiority | Bandit stronghold development | Political intrigue and conquest | Comeuppance and comeback | Rousing power fantasy] Modern programmer Su Chen transmigrates into the body of a poor scholar in ancient times, scraping by through copying other people's writing. Before he can enjoy the vanity of being admired, a band of bandits kidnaps him and takes him to their mountain stronghold. The stunning chief announces imperiously, "I've taken a fancy to you! Marry me and join our Blackwind Stronghold as a live-in son-in-law!" Su Chen is dumbfounded, but the AI in his mind is unusually clear-headed: "Ding! Host faces a historic decision. Will you accept?" The gentle yet forceful first-in-command, the fiery and hot-tempered second-in-command, and the mysterious third-in-command with a fragile disposition are all stunning beauties, and they're sisters! With the AI's guidance, Su Chen plays the pampered husband on the surface, while secretly using its knowledge to transform the stronghold. He smelts steel in blast furnaces, paves roads with cement, improves firearms, and even modernizes healthcare and sanitation. When the imperial army arrives to wipe them out, they don't find a ragtag mob. Instead, they face the beginnings of a modern army, well-equipped and rigorously trained! Using tactics developed by the AI, Su Chen repeatedly turns the tables against stronger foes, transforming the stronghold into a paradise in a chaotic age that everyone longs to find. He wins not only the hearts of the three chiefs, but also the support of countless commoners. "AI, should we dig a canal next, or improve the farm tools?" Su Chen asks softly, his arms around his beloved wife. The AI replies in its cold voice: "Host, based on an analysis of the current situation, the most urgent task is to claim the world!"
