A graduate student in the Department of Modern History unexpectedly passed through the soul of Emperor Yang Guang of the Sui Dynasty who was thirteen years old. At this time, the Sui Dynasty was surrounded by Wagang and wars were everywhere. Outside, Li Yuan raised troops and divided the country. There was only one year left before the death of the country.
Faced with the mess that has been infamous in history for thousands of years, he abandoned his arrogance and ignorance, and used modern knowledge and forward-looking vision to turn the tide: he temporarily stopped fighting to stabilize the situation, opened warehouses to provide relief and calm the people's hearts, rectified the official administration, and promoted the frenzy of technological innovation and infrastructure construction - building roads, connecting canals, building internal combustion engines, mass-producing cars, and establishing a national transportation and industrial system.
Surrounded by the fat man's guard who is greedy for money but loyal, he has gathered under his command heroes such as Li Mi, Dou Jiande, Zhai Rang and other troubled times. While resolving multiple crises such as mutiny, rebellion, and time and space chaos, he promotes technology sharing, people's livelihood, and trade interoperability, and gradually builds the crumbling Sui Dynasty into a prosperous dynasty with leading technology, national peace and security, and all nations coming to the dynasty.
