Lingxi, the most famous female medical officer in the Nine Heavens, could not bear the war, plague, and devastation in the world, so she asked the Emperor of Heaven for her life: She must use her body as a doctor to save the suffering of the world, and accumulate enough merits before she can change her life to peace. With her heavenly medical skills and the golden finger of space waiting to be awakened, she was reincarnated as Lin Xi, a 21st century surgeon. She refined top-notch Western medicine technology and public health thinking in the modern emergency room, but died suddenly due to overwork.
After a second time travel, Lingxi came to the Dayin Dynasty where wars were frequent and plagues were raging. She changed her name to "Su Yixian" and embarked on the road to save the people with modern medical memory and space (including medicines, equipment, and technical materials). From border typhoid fever to capital smallpox, from cholera epidemic areas to post-disaster schistosomiasis, she used the combination of traditional Chinese and Western medicine to solve hundreds of difficult and miscellaneous diseases. She created original concepts of isolation and epidemic prevention, immunization, and health city planning. She established hospitals, medical schools, and epidemic prevention systems, trained countless local doctors, and led the people to rebuild their homes and revive life from the ruins.
Her benevolence and medical skills shocked Emperor Xiao Che of Dayin who paid a private visit incognito. This emperor, who worked hard to govern but suffered from the decline of people's livelihood, went from initial admiration to later crazy love. He cleared the obstacles in the court for her and made an oath of eternal love. When Lingxi reversed the fate of the world with her merits and allowed Dayin to usher in the dawn of prosperity, Xiao Che fulfilled his promise-employed thousands of miles of mountains and rivers to help her ascend to the top of the Ninth Five-Year Plan and become the unique "Miracle Doctor Empress" respected by all people in history. Her story is a legend of the benevolence of a doctor, and a historical record of governing a country like a doctor.
