While many time-travelers were still thinking about burning glass, making soap, and becoming the "returnee faction" boss, Su Nian, a female doctor of archeology in the Department of History at Beijing Normal University, "didn't take the ordinary path." She was forced to wear a white lab coat and traveled to a Northern Wei palace that was in the throes of the "Sinicization Reform", becoming the palace maid next to the emperor who "only caused chaos".
Facing the treacherous court, the ferocious martial arts group, and a group of colleagues who only use modern knowledge to "pretend to be gods and ghosts". Su Nian had no system or golden fingers. Her only trump card was the model called "Big Data Quantitative Historiography" that she wrote into her master's thesis the day before time travel.
Others rely on physical fitness and appearance to travel through time, but Su Nian relies on rigorous academic research and data deduction. While the stupid prince was still struggling with the difference between his legitimate sons and his concubine, and when the paranoid villain was still framing his loyal ministers, Su Nian had already discovered in the ruins the "big granary - Khitan soil" that could support the economy for the next hundred years.
When the emperor stood at the peak of power and was confused about having "no successor", Su Nian used the simplest and crudest "imperial pedagogy + imperial examination system reform + KPI assessment" to create a "spiritual iron army" that could crush everything.
