A time-travel countdown suddenly appeared in Yang Guang's mind, telling him that in one week he would time-travel to the 14th year of the Sui Dynasty and become Emperor Yang of the Sui Dynasty. And he awakened a passive skill. In the Sui Dynasty, there was an unlimited supply of porridge and pickles! He directly posted a message on Zhihu asking for help. What if he traveled through time and became Emperor Yang of Sui Dynasty? Will those who served in ancient times resist if they were only provided with white porridge and pickled vegetables? Zhihu big guys have offered suggestions. Travelers must have completed the three sacred books, all textbooks from primary school to university, and all technologies such as steelmaking, thermal weapons, shipbuilding, and steam engines. Yang Guang used his photographic memory to study crazily, and successfully traveled through time a week later, using the knowledge and technology he learned to develop his power crazily! A few years later, he already controls most of the world's wealth, is the controller of the only thermal weapons army, and has a fleet that sweeps the world. The Sui Dynasty is already an empire on which the sun never sets! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
