In this chapter, we learn that the sect leader has broken the "phoenix martial sting" by using the "returning sincerity" mantra in his own body. We also learn that this is the same technique that the old man used to break the "Phoenix martial sting." The old man taught the new sect leader how to do this, but he didn't tell him the exact same thing. The two of them are bitter because they're both from a different family, so why are they bitter toward one another? They're born with the same family, which is why they don't like one another. They can't compete with one another for the leadership position of the sect, so they have to kill each other. They've already agreed to this, and it's time for them to do it.
