Shen Xi, a master of surgery, traveled through time overnight and became an orphan girl in the last years of the dynasty whose life experience remains a mystery. Faced with the desperate situation of starvation and war, her silver needle can save one person, but it cannot save the world. Until she met Ying Zhaoshuo, a down-and-out prince who had the world in his heart but was trapped in reality. The two reached a consensus: to rely on medical skills and survive on infrastructure. Ye Qiu used modern knowledge as an edge, starting from improving farm tools, building water conservancy, and establishing an epidemic prevention system, and built "Xin'an City" brick by brick in the desolate land where refugees gathered. Concrete roads replaced mud, schools were filled with the sound of reading, and workshops produced artifacts far ahead of their time. However, prosperity touched the old aristocratic cake headed by the prime minister, and conspiracy and destruction followed. At the same time, the shadow of the northern barbarian cavalry moving south is approaching day by day. Shen Xi must complete the final puzzle of this ideal city amidst the overt and covert attacks of the powerful and the countdown to war. Her needle can determine not only life and death, but also the fate of mountains and rivers, and draw a blueprint for a new world on the ruins of the old era. The starting point of all this stems from the unfulfilled regrets and responsibilities contained in the photo from the future in her portable medical book.
It's okay, good-looking, good-looking.
