Years of Peace is a female-oriented transmigration novel centered on strengthening a nation through medicine. It spans forty chapters in six volumes, totaling about 130,000 words. The story features a strong female lead and a career-focused plot with no romance, while political intrigue is shown through its consequences rather than serving as the main storyline. It is set in a world where four kingdoms stand in opposition: Chen has a deep medical heritage but is weak and unable to protect its treasure, Yan has the strongest military, Qi is wealthy through trade, and Qin prides itself on refined ritual and music. Chen is mired in a triple crisis of military weakness, economic hardship, and a shortage of talent. Chen Anning, a twenty-nine-year-old modern emergency physician who fought epidemics, dies in the line of duty in an epidemic zone and transmigrates into the body of the young daughter of Chen Yongnian, the prime minister of Chen, who lies gravely ill and near death. She pieces together her memories in this unfamiliar body, heals herself, and is reborn. From then on, armed with her modern medical knowledge alone, she becomes caught up in the fate of an era.
