None of the people present were idiots. They were all heroes in the past. Although their cultivation base might not be as high as the people from The Fiend sect, they were no less calculative than the people from The Fiend sect when they fought with others. Therefore, they were very clear about what it meant when the other party called them lowly commoners from the lower realm.
They used to be upper-class people. In their eyes, those ordinary people were just lowly people. They had never paid attention to the life and death of those people. Putting themselves in their shoes, they could clearly understand what kind of attitude the other party had towards them.
