Since Inquisitive Sky Hall Master was not too willing to tell the other four teachers of the convention, Xue Ying would naturally not oppose him.
Even though there were rumors about this, firstly, rumors were rumors and would only be temporary and secondly, it was the minority who felt that Xue Ying's decision of selecting Xing Huo Xun Yi was unfair!
The talented cultivators who participated in the convention would usually be concerned about this and would tend to collect information about it. They would understand that Xing Huo Xun Yi was the son of 'Monarch Xing Huo', and had cultivated for more than 500 billion years. He was merely ranked at about 3,600th, and they would feel that it wasn't fair… there were also some of the higher-ups from the six great holy grounds who were concerned about this convention who would try to understand the matter.
