Xu Qingzhi, a master's degree student in civil engineering, was still having a passionate conversation with her instructor during her final defense, and the next second she transformed into an ancient peasant eldest sister with a humble family and many younger siblings. Good news: People are still alive. Bad news: My home is in Qinglong County, a desperate place where there are no birds pooping and there are nine floods in ten years. Floods occur every year and the fields turn into vast oceans. In addition to worshiping gods and Buddhas, the villagers drag their families and families to escape the famine. Looking at her hungry brothers and sisters and the desperate villagers, Xu Qingzhi silently picked up the pitchfork, oh no, it was a measuring pole. "What kind of dragon king do you worship? What kind of destiny do you believe in? Get up and build infrastructure!" Folks: Is this little girl from the Xu family stupid because of the water? Best Relative: Can that poor guy be used as food? It's better to sell your siblings for money! Faced with doubts, Xu Qingzhi was too lazy to talk nonsense and went straight to work. Surveying the terrain, building water conservancy, burning bricks and making pottery, improving farm tools... Scientific farming, targeted poverty alleviation, a combination of punches that will make God confused. The flood is coming? Sorry, the newly built dams and canals make it impossible to come back. By the way, it can also silt out the land and raise fish. Are the bandits coming? Oh, learn about fortresses, traps, and moats, and ensure that they experience the cruelty of an ancient version of a tower defense game. When the mudflat that was once turned into a land of fish and rice, well-known far and wide, with easy access to trade routes and prosperity for everyone, the faces of those who mocked her were swollen. But, why did the amnesiac man who she picked up from the mountain look more and more strange in his eyes? A certain rough guy (whose real identity is the prince who visited privately incognito): "Zhizhi, Jiangshan is my betrothal, how about marrying me?"
