Civil engineering PhD Shen Yanzhou time-travels to the Great Zhao Dynasty, waking up with only starving refugees and a dilapidated temple around him. The State and Dynasty Construction System activates: he burns lime, makes cement, builds official roads, regulates river channels, and settles 100,000 refugees, walking all the way from the ruined temple to the Golden Throne Room. Merchant Su Wantang joins hands with him, spreading the Su Merchant Association across seven provinces. The emperor both uses him and fears him, while the aristocratic families both hate him and cannot stop him. Over ten years, Shen Yanzhou rewrites the national fortune of Great Zhao with cement and blueprints: roads are built, and so is the national fortune.
