Chen Mo, a doctor of modern architecture, accidentally passed through the Great Yan Dynasty and became a scapegoat in a small border town who was about to be killed. Faced with the desperate situation of starvation, corruption in the officialdom, and the presence of barbarians, he relied on his knowledge system that was thousands of years ahead of his time and his bottomless scheming strategies to embark on the road of changing his destiny against the odds. From the construction of the first reservoir to the establishment of a complete industrial system; from an abandoned prisoner to the actual person in charge of power. On the surface, he is an upright official who prays for the people, but secretly he is playing a shocking game of chess. The powerful officials in the officialdom regard him as a thorn in their side, the political forces are eyeing him, and the enemy's spies have repeatedly assassinated him. However, when everyone thought he was just a lucky "genius from heaven", Chen Mo smiled at the edge of the cliff and threw out his real trump card - using modern knowledge to crush ancient conspiracy and using dimensionality reduction to create a legend. In this strange land, he not only changed the direction of history, but also redefined what it means to truly "strategize."
