I, a science student preparing for the college entrance examination, took with me the knowledge of an entire library and became a slave about to be buried on the border of Daqin. In the court, hundreds of scholars laughed at me for being of humble origin and not knowing how to govern a country. I spread out the Daqin version of the national map with my backhand: "Your Majesty, the first question - how to make the Daqin Railway connect the north and the south in three years?" When I photographed the "Five-Year Development Plan" in front of Ying Zheng, the civil and military officials of the Manchu Dynasty thought I was writing a myth. Until I made hundreds of steel in my left hand, made simple fertilizers in my right hand, optimized taxes with mathematical models, and improved crossbow machines with physical laws... Confucianists were confused: "Why does this man's theory not talk about benevolence at all?" Legalists were confused: "Can the law be revised with statistics?" Ying Zheng held my hand, with a glaring look in his eyes: "My dear, the stars and sea of Great Qin begin with your 'examination paper'!"
