No matter what the original intentions of the Canglang Palace were in instigating this conflict, Pei Xuanjing knew one thing - that everyone was now waiting for his response, and based on his actions this time, would determine their attitude towards him.
If Pei Xuanjing chose to back down and soothe the anger of the Canglang Palace, it would mean one thing - he was admitting defeat. This would make other forces think he was weak, and might encourage them to gang upon him like a pack of hyenas, tearing at him to seize any advantage. Thus, Pei Xuanjing would not back down or compromise.
Moreover, he was not the one at fault this time, so why should he back down?
True, this conflict had somewhat disturbed Pei Xuanjing's original plans and was somewhat unexpected.
But after some consideration, Pei Xuanjing found that this was also an opportunity - an opportunity to make genuine contact with the forces of the Sky Wasteland.
