Chen Zian, a doctor of modern medicine, accidentally traveled to the second year of Zhenguan in the Tang Dynasty and became an inconspicuous young man outside Chang'an City.
He originally wanted to practice medicine in a low-key manner and live a stable life, but during a polo match, he rescued the prince Li Chengqian who fell from a horse and fell into a coma. From then on, this young doctor who was full of modern medical science became the prince's most trusted friend.
"Zian, do you think I can still stand up on these legs?"
"Don't worry, your highness. With me here, you can not only stand, but also run and jump. You will be the best emperor of the Tang Dynasty in the future."
Chen Zian smiled, but as he smiled, he remembered Li Chengqian's ending in the history books - he was abolished for his rebellion, exiled to Qianzhou, and died in depression.
Since God allowed him to come and made him good friends with the prince, don't blame him for not practicing martial ethics.
Cured Du Ruhui's terminal illness, saved Wei Zheng's lungs, and nursed Empress Changsun's health along the way. Yu Chigong's gout, Cheng Yaojin's old cold legs, Qin Qiong's old injuries... He took care of all the health problems of Zhenguan's famous officials!
But Chen Zian soon discovered that medical skills can cure diseases, but they cannot cure people's hearts. Changsun Wuji's suspicion, Li Tai's ambition, and the undercurrents in the court... He will use the wisdom of modern people to accompany Li Chengqian through the most difficult years, and he will also help this tragic prince change his destiny that is destined to fail.
This is not only a history of medicine, but also a life-and-death relationship that spans thirteen hundred years.
In the prosperous age of Zhenguan, as long as I am here, the prince will not rebel, and the Tang Dynasty will not decline.
