It was only a matter of time before the sparks of violence turned into flames of war. Arthur couldn't let that happen.
So he had to take a break from studying formations to step in and put a stop to all the fighting. He also decided to make some changes to the games, such as removing the ranking list.
Unfortunately, he couldn't make this change because Purple Vine interfered. In fact, Purple Vine's actions only riled up the disciples of the Purple Flower sect and made them more violent.
If the patriarch of the Purple Flower sect hadn't appeared to calm the situation down, the fighting would have escalated. What the Patriarch did was to give Arthur permission to make any changes that he wanted to the exchange program.
This permission allowed Arthur to remove the most important source of conflict between both sides. The issue wasn't eliminated completely, but everyone calmed down and got to live along with each other for the next few months.
