Ye Qiu, a modern surgeon, possesses peerless medical skills and engineering knowledge that transcends the times. However, due to an accident, his soul traveled to an fictional ancient dynasty called "Dayin" and possessed the body of an orphan girl who was abandoned by her family. The beginning is a refugee camp on the edge of famine and war. With the silver needle technique of "living dead people, flesh and white bones", she rescued the down-and-out prince Xiao Jingxing (male protagonist) whose life was hanging by a thread, and the two formed a life-and-death friendship. Ye Qiu knows very well that it is easy to save one person, but difficult to save the world. She was no longer satisfied with practicing medicine. Instead, she started from the refugee camps and used modern knowledge to burn cement to strengthen the dams, improve agricultural tools and crops, and build simple medical clinics and schools. What she did quickly touched the interests of the conservative faction headed by the prime minister. From cutting off her building materials to exposing her sorcery, there were constant obstacles. At the same time, the barbarians in the north are ready to take action, and the country is in danger. Under Xiao Jingxing's recommendation, the emperor gave Ye Qiu an "impossible task": to build a deserted "land of sinners" into a self-sufficient fortress that can provide support for the front line within one year. Ye Qiu and Xiao Jingxing join hands, one is responsible for technical research and people's livelihood management, and the other is responsible for dealing with the court and integrating resources. What they face is not only natural and man-made disasters, but also confrontation with the entire rules of the old era. The modern medical book and photos Ye Qiu locked in the drawer are not only the secret of her time travel, but also involve an amazing past event about the origin of this dynasty. Finally, when a brand-new city was built on the wasteland and the barbarian iron cavalry approached the city, Ye Qiu stood on the city wall. The silver needle in her hand saved not only human lives, but also the fate of the country.
