The Australian's representative was not expecting to blow this off like this. He just wanted to test the water out before making an actual exit. He looked around and the people around him either shook their heads or looked away from him. They drew a clear line that they did not want to get involved in whatever he stepped into.
He met with The Emperor's eyes and quickly realized he was not joking. The Emperor was serious about kicking him out. Even with those three choices presented to him, there was no choice for him to turn back. The choice was very clear that The Emperor did not like him and wanted him out. Giving back the territories that Yu Shun captured might be a choice, but he did not know what The Tang Empire would do to him. There was a big chance that The Tang Empire would declare war against his faction and take over Australia the same.
