In this chapter, we learn that Dr. Manette's skill in butterfly acupuncture and his command of thirteen ghost needles are essential to his ability to master the huaxia system. He also learns that if he is to become a master of the system, he will need to be recommended by three other masters. Doctor Manette tells the others that he is sorry that he did not have time to greet them, but he will take them to the trial grounds. He tells them that he does not understand the medical book, which he has been studying since he was forty years old. He hopes that someone will be able to understand the book and fulfill his wish in his lifetime.
