What Lin Zhen did was so shocking it can't be described as merely out of the ordinary.
Overtly insulting Lin An, especially in front of so many people, there probably wouldn't be a second person in all of New World bold enough to do so.
Who was Lin An?
He was the second son of Saint Ancestor Lin Zhen, and it was said that the Saint Ancestor tremendously cherished his children. Two sons and a daughter, each were the apple of Saint Ancestor's eye.
Once, his two sons were stranded in the Original World and the Saint Ancestor single-handedly stormed this world, stirring up chaos, and beat the Imperial Clan till they were running all over the place, rescuing both sons. This demonstrated just how much he loved his children.
Risking verbal insult against Lin An was simply a death wish.
Not only was Lin An humiliated, his mother too was insulted.
