Dayuan Shuangxing: Faxiao and I Share the Infrastructure System

Modern heroes accidentally crossed the Great Abyss. One became the son of a poor farmer, and the other became the legitimate son of a military commander in the capital.

Xie Yu was taking imperial examinations and making inventions in the south of the Yangtze River, while Xiao Jiming was killing enemies at the border and accumulating points. The two exchanged knowledge across thousands of miles and crazily climbed the technology tree. There are no super relatives or bloody villains, only the emperor and the empress end up stumbling upon CP. Let's see how two infrastructure madmen, one civil and one military, use modern knowledge and system plug-ins to revolutionize the Dayuan Dynasty and create an eternal prosperous age!
