In this chapter, we learn that feng-hao's martial arts skills are different from those of ordinary practitioners. He uses a technique called "yellow-grade" to train his physical strength and he uses "martial-secret script" to teach his other skills. The elder feng tells us that there is only one person in the family who can use this technique at a high level. He says that he will help him when he changes the master of his family. He is proud of his son's ability to use the yellow-grade technique. He tells the elder feng that although the skills he gave him are powerful, he has to wait until he recovers before he can use them again. He explains that there are two professions in the area of tian-wu: pharmacists and poison masters. The first is the noble profession of treating illnesses and injuries, and the second is the profession of creating poison pills. According to pharmacopeia, the first profession is to swallow the medicine and condense it into a capsule. The second profession is the practice of making poison pills, which is the worst profession on the mainland. This is why pharmacists are called "poison masters" because they are so evil.
