The Rebellion's Quack Doctor

I died in an unexpected accident, only to wake up possessed by a doctor. Fifteen years as a medical drama fanatic. They say even a dog at a Confucian school can recite poetry after three years, so I learned quite a bit of medical jargon—but a doctor? Really?! To make matters worse, I ended up becoming the personal physician to Jin, the leader of a massive rebel army and a terminally ill patient. But what's with these doctors around here? Pouring boiling oil on wounds? Draining the raw blood from patients who are coughing up blood?!

*“Everyone entering this room must wash their hands thoroughly from now on!”

“The new doctor sure has a lot of rules. Interesting.”*

Three months remain until Jin's predicted death. Can this quack doctor actually save him?
