"Natural Suppression"

Just like how the headquarters' location was chosen because there were a lot of monsters…

The Roid Valley might not be worse than the headquarters because of the number of monsters around. 

The Roidley was finally a bit comforted by this fact and suddenly no longer disdained to be a part of the Roid Valley.

Although Ainsley did send out the worst members to the Roid Valley, she meant to train them harder than the others by using the Roid Valley's geographical advantage. 

With a lot of monsters around, the members had to train hard every single day, unlike those at Butterfly Pagoda, Sloan Village, or the Godfather Mausoleum branch. 

The other three areas didn't have many wild monsters around, so the members couldn't train every single day. 

It could be said that Ainsley put the mediocre members to these three branches. 

On the other hand, she kept the best and the second-best members at the headquarters and the Crimson Lily branch.
