The protagonist "Yang Yifan", a genius surgeon at a tertiary hospital, accidentally traveled to the Ming Dynasty and was mistaken for a "heretic monster" and almost beheaded.
With his superb medical skills and strange modern knowledge (such as hand washing, disinfection, stethoscope, CPR), he counterattacked step by step, and was recommended to join Tai Hospital as an apprentice.
There are endless funny scenes, such as teaching people to gargle and being treated as a "magic trick", using a lighter to light a fire and being treated as a "fairy", and treating a eunuch's aphonia but being chased and shouting "the miracle doctor gives medicine".
He used modern surgical techniques to save a seriously injured prince, gained trust, and officially entered the palace medical system.
