Li Wei, a doctor of modern agriculture, accidentally traveled to the troubled times of the late Tang Dynasty and became an unknown soldier in Huang Chao's army. Seeing starving people everywhere and divided families, he determined to use modern knowledge to transform this collapsed era. From improving farm tools to promoting new imperial examinations, from breaking the monopoly of nobles to establishing promotion channels for civilians, Li Wei assisted Huang Chao in establishing a new regime that was very different from the historical trajectory. However, in the collision of power, tradition and modern ideas, the road to change is far more difficult and bloody than imagined. This is an epic about ideals and reality, tradition and innovation, redemption and price.
