The day I dressed as a fake eunuch, I was preparing to sleep with the imperial concubine.
But she sneered and pointed at the poisoned wine in the corner: "Drink it, I will leave no one alive here."
I took out the stethoscope with my backhand and pressed it on her chest: "Mother, you are happy."
When the imperial concubine panicked, I used modern medical skills to save the emperor.
Three months later, when I was in charge of the Imperial Hospital, the imperial concubine knelt outside the palace and begged me for help.
The new emperor on the throne was playing with my stethoscope with a smile.
