After a car accident, Shen Yan, a modern business tycoon, accidentally traveled to a strange world. When he was about to die, he was saved by Su Huaizhou, a miracle doctor who lived in seclusion in the mountains. In order to survive, he concealed his identity, changed his name to "Su Yan", became Su Huaizhou's teacher, and embarked on the path of studying medicine. During the learning process, Su Yan not only witnessed the magic of traditional medical skills, but also experienced a change in mentality from a business elite to a doctor.
Once, Su Yan tried to independently treat a poisoned teenager when his master was away, but due to a misdiagnosis, the teenager died and shouldered a heavy blood debt. Master Su Huaizhou ordered him to provide for the young man's father, Wang Dashan, to retire and die in order to atone for his sins. This incident made Su Yan deeply understand the reverence of doctors for life, and also made him lose his previous arrogance.
In the long process of atonement and studying medicine, Su Yan gradually grew up and his medical skills became increasingly sophisticated. When he was able to stand alone, Master asked him to go down the mountain to help the world. On the way down the mountain, he met Xiao Jingyan, the current prince, who was poisoned by the strange poison "Blood Jade Spider". Faced with the prince's suspicion and threats, Su Yan suppressed the poison with superb medical skills. A battle involving life, death and power began between the two, and Su Yan's career as a doctor opened a new chapter.
