The fourth brother tells the sixth brother that he can hide his power and sense of smell from the other brothers. The sixth brother says that he forgot that his body is frail, so they won't bother him any longer. The next day, the fourth brother asks why the kid is so crazy when he sees martial arts manuals. The kid says he hasn't eaten or slept since yesterday, so he can't remember what he's read. The martial arts manual, he says, has a secret layer. It's called giant elephant stomp, and it's created by imitating the movement of a giant elephant. If one can master this, he'll have the same power as an elephant, and he will be able to topple mountains and peaks. Unfortunately, some pages aren't included in the manual, so the kid decides to learn the manual first and see if he can figure out where the missing pages are. He says he only has one day left to master the secret art, and if he goes out, he can find a quiet place to train. He'll definitely master this art.
