Xu Zhao, a master of civil engineering from Gou Luqiao, a national first-class registered structural engineer, who has been working with steel and concrete all year round, opened his eyes and transformed into an ancient peasant girl who was about to starve to death on her way to escape famine. Good news: She's alive. Bad news: The game starts in hell mode, with all three sets of war, famine, and plague. Looking at his sallow-looking family members and the refugees all over the mountains and plains, Xu Zhao wiped his face and spoke professionally, everyone. Others fled south, but Xu Zhao led the whole village into the mountains. "How can a bird live in these ravines without pooping?" "Live, not only can you live, but you can also live well." Burning lime, making cement, building canals, building dams, building kilns, building water trucks... Xu Zhao ignited the soul of infrastructure engraved in his DNA! When the first solid rammed earth wall surrounding the building went up, everyone was stunned. While others are still eating chaffy vegetables, Xujiacun has achieved free tap water (bushi). Others were still worried about the bandits. Even the officers and soldiers had to take a detour after seeing the fortifications in Xujiacun. Later, a down-and-out general passed by with his remaining defeated soldiers. He looked at this paradise-like mountain fortress and fell into deep thought. He thought he picked up an ordinary village girl, but he didn't expect that he would find a treasure that could plan a city. General: "Miss Xu, I am willing to use the country as an employer. Please build a few more roads for me...?" Xu Zhao (holding the helmet on the headrest): "Bring me the drawings first. Oh, by the way, what is the budget? The project payment cannot be delayed!" This is a story without a golden finger. It depends entirely on knowledge to change destiny.
