They were all too serious!
It wasn't just Beibei.
Xu Xiaoshou looked back at Lei Shuangxing and realized that this guy had defended Beibei from the very beginning. Or rather, he had spoken up for the 'convention' of the ancient swordsman.
Even Master Siren...
Xu Xiaoshou looked over and realized that his Teacher, who was usually kind, did not look at him at all this time. His expression was calm, but oh that deep furrow between his eyebrows...
He was not being calm, rather it was the case of 'out of sight, out of mind'!
The old sword saint clearly knew what his student was like.
Since he knew that persuasion was futile, Xu Xiaoshou was right from his point of view.
That was because he was determined to stand on Beibei's side. He could not speak up for Xu Xiaoshou, but he would also not ignore his position and speak up for Beibei, who was on the opposing side.
It would be better to keep quiet!
