This was x many times Tang Shaoyang encountered such a thing. The people, for some reason, did not like him and his group and looked for trouble for him. He was also aware that he was the cause of this trouble. He could avoid a situation like this easily by backing down, but he was in the position to do so. If his people saw their Emperor lowered himself just to avoid trouble, he would lose respect from them.
Tang Shaoyang tried to ignore the man, but of course, as usual, the man called Russo would not back down after stepping up. That would hurt his pride which would lead the other adventurers to think he was a coward, 'Is there no other way to get out of this situation without crushing this man's head?'
