"Hmm? How could you know this?"
Hearing Jiang Xiaobai's words, the old man in the blue robe was a little stunned and then looked at him in surprise as if he wanted to find something on Jiang Xiaobai's face.
The corner of Jiang Xiaobai's mouth twitched at the sight of this. He couldn't help cursing in his heart, "Who do you look down upon? Do you think only you can recognize this?"
But he didn't say that because he knew very well that if he said something like that, the old man might not help him.
