This chapter begins with a description of the process of refining a person's body. The first step is to "levy" a muscle and then "crack" it. The second step involves "sapping" the muscle, and the third step involves refining the organ. This is a very painful process, and it's one of the most painful things a person can do. The narrator wonders if the person who invented this process had tried this on his own. He wonders if he's the one who came up with the idea to do this kind of thing. He's also wondering if the man who invented the refining process was the same person who created the first step in the first chapter. This chapter ends with the narrator explaining that he has been practicing this refining process to save his sister.
