Back in the Peaceful Years, I Saved an Emperor Named Chai Rong

After a failed resuscitation, modern emergency physician Shen Yi transmigrates into Shen Qian, a junior medic traveling with the Later Zhou army. He opens his eyes to blood and fire in the military camp, where he uses modern medicine to stitch wounds and clean injuries, and devises a triage system. From an old soldier, he learns that it is the sixth year of the Xiande era, the final year of Chai Rong's northern campaign. This greatest ruler of the Five Dynasties has less than a year to live, while Zhao Kuangyin's Chenqiao mutiny is already brewing in secret.

Seeing history's course at a glance, how could he stand by and let the chaos continue? Beneath Youzhou's walls, Chai Rong is critically ill with an infected wound. At the risk of his life, Shen Qian operates on the emperor in his presence, disinfecting with strong liquor and stopping the bleeding with a branding iron, dragging him back from the jaws of death. At court, he repeatedly outmaneuvers the Imperial Medical Bureau, fights epidemics, and makes alcohol disinfectant, but finds himself caught in the Zhao brothers' tests and attempts on his life, becoming a key piece in their game of power.

He confesses to Chai Rong that he comes from a thousand years in the future, and the two pledge themselves to one another as ruler and subject, joining forces to defy the inertia of history. Again and again, he uses modern medicine to fight deadly illnesses and matches wits with Zhao Kuangyin's ambitions, thwarting the Chenqiao mutiny and helping Chai Rong reclaim Youyun. When the age of chaos finally gives way to peace, the physician from a thousand years in the future at last faces the time to return. He opens his eyes in the emergency room again, and the history book on his phone has already been rewritten: Chai Rong's life has taken a different course.
