Tan Yunxian, a female doctor from the Ming Dynasty, traveled to modern times because of a thunderstorm that robbed her soul, just when the new coronavirus epidemic first appeared. After changing his name (Tan Xiaoxian), he integrated into modern times and used the power of traditional Chinese medicine to provide free medical services and save people. However, he fell into public opinion for "practicing medicine without a license" and attracted attention from disease control. The mysterious people Lu Cheng and Su Mo got closer to each other as "protectors", each with hidden family agendas.
In order to search for anti-epidemic medicinal materials, she, Lu Cheng, and Su Mo went deep into the mountains of western Hubei, experiencing life and death along the way. They not only encountered clues about the spread of the virus, but also discovered the undercurrent of family power. After returning, she combined traditional Chinese and Western medicine to explore ways to fight the epidemic, and struggled through medical controversies and family quarrels. The secret rivalry and emotional entanglements between Lu Cheng and Su Mo also became more complicated as the epidemic escalated.
When the results of the fight against the epidemic begin to show, the shadows of forces such as "MG Pharmaceuticals" emerge, and family secrets, emotional choices and new changes in the virus are intertwined. Tan Xiaoxian will use the wisdom of ancient medicine to break the situation. With Lu Cheng's forbearing protection and Su Mo's passionate pursuit, he will write a legend of doctors that spans time and space on the modern anti-epidemic battlefield, uncovering the shocking secrets entangled with intrigues and emotions behind the epidemic.
