Story summary:
Zhang Yan, a graduate of the Medical University, picked up a bronze token engraved with the word "Xuanyuan" in the ancient ruins in western Hunan. From then on, a talkative ancestor lived in his mind - the Yellow Emperor with three souls and seven souls.
Huangdi gave him three things: half of the hidden volume of the "Huangdi Neijing": it can cure all diseases and kill people; a ray of "Human Emperor Qi": which can strengthen the body and read minds through clairvoyance, but it can burn three years of life in one go; a cause and effect spanning five thousand years: the battle that Huangdi did not finish back then is now Zhang Yan's turn.
Therefore, during the day, Zhang Yan was a very poor doctor in the city, and at night he became an "underground miracle doctor" - specializing in treating difficult and complicated diseases and beating up lawbreakers.
