Swallow an Immortal World

The young master asks the old man if he killed some people in the mountains. The old man replies that he didn't kill anyone, but that he killed a bunch of people who were from the same sect. He says that he's not sure if this is a trap, or if it's the force of his secret skill. He asks the young man if there are any gaps between their strengths. The young man says that there are, but he doesn't know if the gap is caused by the secret skill, or by the fact that the two of them are at the same level as each other. The elder of the sect says that the more powerful a secret skill is, the less likely it is to be mastered by a disciple. The more powerful the skill, the more likely a disciple is to master it. The older of the two says that his skill is so powerful that he has devoted years of his life to mastering it. Now, he says, he can't possibly get close to the elder because he has mastered it. He adds that he made some jades from the tomb and put the essence of his skill into one of them so that the elder could use it against him.
