The chapter opens with a discussion between the doctor and the student. The doctor tells the student that the student's illness is incurable, and that he has visited many hospitals to find out the cause of the patient's pain. The student says that he gave the student some painkillers to numb his pain, but the pain was not getting any better. He tells the doctor that the pain is caused by the student using his internal energy, which is a form of internal force. He says that the joints of the knee and waist are aflame, but this is different from inflammation, because the internal energy of the body is not completely destroyed. The patient asks the doctor to teach him a martial art called "Grifling Technique." The doctor explains that this is a technique that was not taught in traditional Chinese medicine, and he has changed it a bit. He asks the student to promise him one thing first: that he will give him a chance to become the doctor of the student, even if he has a hundred things he can still promise him. The physician says that it is not easy for him to be a doctor, as he is just a new student in medical school. He adds that the patient needs to lie on his belly first, and then he can begin to teach the grappling technique. He explains that the technique is very impressive, and to him, it is more urgent that his health. He then tells the patient that he does not need to worry about the silver needles, as they are not able to pierce the skin. Instead, he uses his internal force to pierce through the skin, and the patient feels no pain.
