Li Rui, a modern scholar of Tang history, once traveled through time, became a prisoner awaiting death under Li Shimin's sword.
With his accurate prediction of history, he barely managed to save his life, but was forced to get involved in the turbulent early Tang Dynasty.
Locust plagues, powerful countries, aristocratic families, Turks, battles for thrones... The torrent of history is rolling in.
What he wants to do is not to obey history, but to transform history!
Use statistics to reorganize household registration, use management to optimize logistics, and use a global perspective to redraw the blueprint of the empire.
Smelting steel, forging cannons, and sailing to sea, he wanted to spread the reputation of "Khan of Heaven" to every corner of the world.
However, when he tried to use modern thinking to shake the foundation of the thousand-year-old monarchy, the biggest resistance came not from his enemies, but from the king to whom he swore allegiance to the death, and the peerless woman from five surnames and seven hopes who moved his heart.
When the dimensionality reduction of knowledge hits upon the complexity of human nature and the coldness of power, can a time traveler really transform a great era as he wishes?
