Qin Feng, a time dealer from the future, fell into the fictional historical dynasty called "Daqian" due to the turbulence of time and space. In order to repair the space-time machine and return home, he must collect huge "national luck values". The way to obtain national fortune value is actually to build infrastructure! Qin Feng pretended to be a reclusive "Moji tycoon" and sneaked into the court to bind the infrastructure system. Not only does he have to face the emperor who is extremely imaginative, but he also has to deal with the scheming and powerful officials in the court. He not only built roads and bridges, but also developed cement, glass and even steam engines, turning political crises into business carnivals. In the process, he encounters the heroine, a geologist who also traveled through time. The two of them, one civilized and one military (actually, they are two funny men), went about their business crazily in ancient times, eventually leading Da Gan to a strange development path.
