The sound clearly surprised and startled everyone present there, and especially the people from the Gao family. Mostly because Cui Xie's location and the direction of that slapping sound didn't match.
Their surprise turned into shock the moment that they saw and heard what happened next, as Li YunMu seemed to have slapped her own son, and then scream at him,
"Stop this Jian'er don't you think is enough what you have already done? Do you want to bury this family tonight?"
"Mo-Mother!? But mother he…"
"Shut up, I know already! But he is right, at the moment we can't make a move against him! There are much more important things to care about!"
No one had expected that the woman who seemed to care the most about her son, would suddenly act like that, and treat him like that.
Cui Xie on the other side didn't seem to care much about the scene behind him, as he just continued to walk calmly amidst the crowd and leave the place.
