After Marrying the Princess, I Changed the World

In the fifth year of the Zhenguan era, Du Heng, a 24-year-old modern engineering student, accidentally transmigrates to the outskirts of Chang’an in the Tang Dynasty, becoming a destitute 14-year-old orphan.
With no System and no “Golden Finger” cheats, relying solely on modern knowledge, scientific thinking, and historical foresight, he starts from a half-acre barren garden. He stuns the Emperor with a single stir-fry dish and shakes the royal court with a piece of glass.
He establishes the Institute of Science, developing penicillin, forging horseshoes, and promoting movable type printing.
He opens the Xiaoyao Tower restaurant, creating a membership system, advocating for food traceability, and leading public opinion reform.
He assists General Li Jing in defeating the Turks, presenting a sand table to secure Yin Mountain, reshaping the martial prowess of the Great Tang through technology.
Joining hands with four extraordinary women, Princess Changle, Princess Gaoyang, Wu Xu, and Zheng Liwan, he builds a family and national structure of “Four Pillars Co-governance.”
From cuisine to medicine, from glass to steam power, from Chang’an to the globe—
He does not vie for power, yet becomes the pillar of the empire;
He does not seek vain fame, yet rewrites a thousand years of civilization.
After Marrying the Princess, I Changed the World tells the story of how an engineering student uses the spirit of science to quietly ignite the spark of industrial civilization during the prosperous Zhenguan era, ultimately guiding the Great Tang on a magnificent journey to becoming an empire on which the sun never sets.
