The heroine is a time traveler, and the identity she has traveled through is a vicious female supporting character in the original novel who cannot survive the first three chapters and specializes in giving the heroine experience and throwing dirty water. What's even more frightening is that a "evil villain growth system" is bound to her brain. Every task issued by the system is to guide her to persecute the original heroine and eventually send her to the guillotine. But she doesn't. This "anti-bone boy" uses the system's rewards (medical skills, prescriptions, and insight into the disease) to save lives, cure illnesses, and save lives, turning all events that persecuted the heroine into opportunities to save the heroine. Under the watchful eye of the system, she wants to forcibly reverse the fate of the "evil female supporting role" and live her life as the kindest and greatest female doctor in the entire capital.
