She is a well-known and beloved eldest daughter of the Tang family. In an accident, she suddenly traveled to a dynasty that has not been recorded in history. The medium of time travel is actually the jade pendant left to her by the old man when he died. This dynasty is very backward and the people are miserable. Let's see how I, the academic master of Imperial University, can help you live a prosperous life, build city walls with cement... Let's build infrastructure together, and let's build a beautiful socialist life together...
Intention: time travel - the eldest lady is coming, everyone gets out of the way
