Lin Qingqian, a cardiac surgeon in the 21st century, opened his eyes and became a whipped maid in an ancient medical hall. Before she had time to digest the fact of time travel, an exclamation came from the front hall: "Guanshi Zhang is out of breath!" She rushed forward and used the "death technique" cardiopulmonary resuscitation to revive the person. The stethoscope slipped from her arms. It was her only connection with modern times. Overnight, the name of "Miracle Doctor Maid" spread throughout the county. When the county magistrate's son was kicked by a horse, she used suturing to stop the bleeding and save his life; when a wealthy businessman suffered from stomachache for ten years, she gave him a new life with a bowl of soup; when cholera broke out, she isolated and disinfected it and saved the people in the city. Late at night, Xiao Chen, a man in black, broke in injured. She sutured his wounds, but she didn't know that the man who pursued her awkwardly was actually the prince of the court. From a maid to an imperial doctor, from being framed and fleeing to being rehabilitated, she used modern medical skills to save danger time and time again. On the wedding day, Xiao Chen announced in public that he would abolish the harem and marry only her. She promoted modern medicine, established hospitals, trained medical students, and was posthumously named a "Medical Saint." This is a story about a modern female doctor who uses her medical skills to counterattack in ancient times and falls in love with a cold and aloof prince.
