From the Start, the Exiled Prince Crushes Six Kingdoms with a Single City

[Modern special forces soldier transmigrates into a hostage prince of a fallen kingdom + advanced technology crushes all opposition + an empress falls for him + power struggles among the nations spiral out of control] Xu Xian opens his eyes and finds himself the eldest prince of the recently fallen Great Yu dynasty, a useless prince demanded as a hostage by the country that rebelled against them! His birth mother was the daughter of a rebel general, and her entire clan died in a sea of flames. Now the powerful figures of six kingdoms treat him like a dog. The southern Yue officials mock him for his ignorance, the western Zhao poison doctor wants to use him to test medicine, and the barbarian cavalry plan to force him to crawl beneath a horse’s belly… But no one knows that the soul now inhabiting this body belongs to a 21st-century military engineer! When the barbarians besiege the city and demand the hostage prince’s head to use as a chamber pot, Xu Xian pulls out a machine tool and builds an AK. When the strategists’ secret guards come to slit his throat in the dead of night, a flashbang blinds them. When southern Yue’s literary talents mock his lack of refinement, the timeless poems he recites leave their leading scholar vomiting blood and dying! At court, the old emperor is critically ill, the second prince’s parentage is in doubt, and his five-year-old younger brother clings to him and cries, “Elder brother, take me with you.” Xu Xian touches the blueprints for a steam engine he has just drawn, looking at the spies and advisers of the strategists, the saintess of the farming school, and the traitor from the Mohist school kneeling across the great hall. “I don’t need the throne! But none of you from the six kingdoms will get out alive!” “One day, I’ll crush the six kingdoms with science and flatten the barbarian steppes with internal combustion engines!” “As for the mastermind who set fire to my clan…” He stares at the divination poem from the strategists hanging behind the imperial throne and smiles ominously. It’s time for an engineering-minded man to make the rules of this world.
