The spirit of Zhao Xuanni, the school belle from the Department of History, traveled through the Qin Palace and became the concubine of Ying Zheng. In order to survive, she silently wrote "Ten Questions on the Downfall of the Qin Empire" overnight. Ying Zheng was furious after seeing this, but the next day he summoned her into the inner hall with dark circles under his eyes: "How can I make my four-horse chariot break eighty miles per hour?" Zhao Xuanni raised his forehead: We agreed to burn books and humiliate scholars, but why did it turn into providing me with a laboratory? Since then, Daqin has had cement roads, telescopes, and blast furnaces for steelmaking. Seeing that the empire's iron hoof was about to crush the sky, Zhao Xuanni quietly disappeared in Ying Zheng's arms. When she opened her eyes again, she was lying back in her university dormitory. The phone vibrated, and a text message from "Eternal Emperor" popped up: "Ni Ni, the radiator in Xianyang Palace is leaking, please come home quickly."
