Dong Zheng stared at Cheng Sheng and felt torn between helping Cheng Sheng and continuing to hate the foreign enemies. But, he knows whatever his decision is, it doesn't matter, since he knows well that what Cheng Sheng said is correct. If Cheng Sheng wanted to leave to help the foreign enemies save their sect leader's life, who could stop him? Even if Cheng Sheng is not the strongest sword cultivator, he is just not a sword cultivator. He is also a mage, and he is the strongest mage! Cheng Sheng even made the mages rise in the cultivation world!
