Duan Youhun, a Ph. D. In Physics, traveled through the late Han Dynasty and became a crippled young master of Liangzhou Prefecture, awakening the overlord system. He used distilled spirits to poison his enemies, used lever traps to capture famous generals alive, and used black powder and steam engines to usher in the industrial era. He raised troops in Liangzhou, burned the Wengcheng to force Lu Bu to retreat, and threatened the emperor to command the world; he used tear gas and heartless cannons to sweep Cao Yuan, and Chibi used a steam ironclad ship to smash a serial ship. He ascended the throne and established the Daliang Empire, ushered in the age of electricity, pacified the Shu-Han Dynasty, conquered Rome, laid out a global railway network, and finally led the Daliang sword to point at the sea of stars, creating the legend that the sun never sets.
