There is a remote town near Guiyuan Kingdom. There is a doctor living in the town. People in the town come to him if they have any minor fevers, ailments or difficult and complicated diseases. The price is affordable and the medicine can cure the disease. He is really a miracle doctor.
This miracle doctor's surname is Cheng. No one has ever asked his name, and no one knows where he comes from. They only know that he suddenly appeared in the town eight years ago, looking sick and frail. He bought a thatched house in a remote part of the town and settled down. Since then, there has been an additional doctor in the town.
Until someone appears...
