"Alright, speak up then! We are listening." Although they were somewhat dissatisfied with Zhou Tian's attitude, just as Zhou said, they were already here, and it would indeed be inappropriate if they left without even communicating with Zhou Tian.
Of course, because they had no expectations of Zhou Tian, those Sect Masters had already made up their minds. If Zhou Tian's next words didn't carry significance, then there would really be no need to continue this meeting. And at that point, even if Zhou Tian begged them, they absolutely wouldn't stay any longer.
