Hu Die, a double doctor of modern history and geography, accidentally traveled through time and became Hu Die'er, the daughter of the Taifu of the prosperous Tang Dynasty. With the knowledge of two generations, she helped the low-key and tolerant third prince Li Ke step by step in the turbulent times of the late Zhenguan years, and broke out of the battle for the throne and ascended the throne.
During this period, Prince Wenrun abstained from power for her, and the second prince Iron-blooded helped her expand her territory, and her relationship with Li Ke became more intense amid intrigues and wars. Taking history as a mirror and the land as a plan, she not only assisted him in creating the prosperous age of Taihe, but also became the only queen in his life, writing a legend of "mountains and rivers as evidence, a pair in life".
