Wa Lun clasped his hands together and said, "Brother Cheng, you are proficient in formations, so we will all listen to you now. Whatever you say to do, we will do."
As soon as Wa Lun spoke, Yu Wanyue and the others who had come up expressed their willingness to follow Ning Cheng's lead. They heard the noise outside growing louder and louder, and the cultivators outside, even if not familiar with formations, should be able to break through the formation very soon given this kind of attack. It was clear that Wa Lun and the others were worried that they wouldn't have broken through the formation before them by the time the cultivators outside invaded.
Ning Cheng didn't waste words. He directly said, "Since that's the case, I won't stand on ceremony. Everyone pay attention to where I throw the Array Flags. As soon as I throw down a flag, immediately concentrate your attacks there."
