Purity went silent when they heard Chu Yunfan's words. None tried cursing him again. They only dared to curse him before because they thought he was overestimating his strength.
However, they finally understood why Chu Yunfan was so confident—because he had the strength to back up his words. Purity could not fight back if he had decided to destroy them.
Even if Purity had Nine Stars' help, Chu Yunfan could kill all of Purity's experts. He did not need to kill everyone in Purity to cause the sect to collapse. There was no doubt about it.
Purity could not help but feel resentment toward their sect master. They dared not feel such resentment toward Chu Yunfan because they knew he could destroy them with just a word, no different from crushing an ant with a boot.
