Xing Yingyuan, a doctor of science and engineering, mysteriously crossed the city wall of Xi'an and became a poor orphan girl in the Dasheng Dynasty. Faced with an existential crisis, she backhandedly revealed her "technology tree": making perfume, refining steel, and making cement... She just wanted to make money and settle down, but she accidentally became famous in Chang'an, and was even targeted by the seventh prince Yun Kaiji, who was rumored to be "not doing his job properly." He promised her unlimited resources and absolute protection, and invited her to work together to create an earth-shaking revolution. From then on, she was responsible for the amazing skills that shocked the world, and he was responsible for the power to determine the country. When modern thinking collides with ancient royal power, they join forces to create the most unscientific and prosperous age.
