I Am the Youngest Son of Emperor Yang of Sui Dynasty, but I Can Return to Modern Times at Any Time

Ye Chen, a gold medal lawyer, was framed and became a delivery boy. In a car accident on a rainy night, his soul transformed into Yang Gao, the youngest son of Emperor Yang of Sui Dynasty, and he was trapped in the Jiangdu rebellion.

When Yu Wenhua was regicide and usurping the throne in Jiangdu, Li Shimin was building troops in Taiyuan, and Du Fuwei was galloping across the Jianghuai River - Ye Chen lit the first electric lamp on the deserted beach of Taihu Lake, used modern steelmaking methods to make the first Tang Hengdao, and set up an intelligence network covering the south of the Yangtze River in the dark.
