The next day Senior asks if he can learn by himself how to make things. He sees that they have books on how to do it, so he asks to be taken to the forge room. Senior tells him to read the book first, and then practice with iron bars. He says that those who can make things with ordinary iron will be the real craftsmen, not the students who can do it with rare metals. Senior says that he can't feel the energy of ordinary iron as strong as it does from rare metals, but he can feel it when he strikes a bar. He kneads it, and it shrinks again.
