Jiang Wanqing, a 16-year-old medical girl, went into exile because her family was ruined, so she became a maid in the palace with her family's medicinal diet. The ten-year-old prince Liu Ming woke up from a coma, his eyes were like those of an adult, and he uttered "sterile" surprises - he turned out to be Lin Jingming, a doctor of traditional Chinese and Western medicine who had traveled through time.
When they first met under the cliff, she saved his life with a golden needle; when they met again inside the palace wall, he protected him secretly with his childish body. From the Department of Medicinal Food to the Imperial Medical Office, from treating existing diseases to "treating pre-diseases", she used "Shen Nong's Materia Medica" as the guideline to integrate medicine into the diet to fight epidemics and save people; he used modern medical science as a guide to secretly plan and promote changes.
Four palace romances are intertwined, and political intrigue and medical ethics collide. From the Fuzi transfer case to the smallpox epidemic prevention war, from the witchcraft disaster to the marriage in the Western Regions, they got to know each other in crisis and stayed with each other in life and death. He said: "From now on, I will taste every medicinal meal you make first." She gave a five-color medicine bag in return: "May your highness always be healthy." (This story is fictional)
An agreement spanning a thousand years, a reunion of ancient and modern medical minds. When the magnetic needle of the Han Dynasty reappears in 2025, and when the heartbeat frequency is fixed at 120 again - the medical ideal that has not been fulfilled in the previous life will eventually illuminate the world in this life.
This is a vow of love that transcends time and space, and it is also an inheritance of the immortal kindness of doctors.
Purpose: Doctors are benevolent, medicine and diet can cure diseases, and benevolence helps people.
