With the matter concerning Nathan already dealt with, Sarah, Diana and Olivia did not have to continue staying within the military territory while waiting for the leader of the territory to come over anymore.
So, immediately after they were informed about the matter concerning the leader of the military territory being dealt with, they immediately organized the territory. Those gold rank soldiers that had come from Trista territory had already been subdued by the three of them.
Then without hesitation, they immediately began making reforms for the territory. And of course, they understood that it was going to take some time for them to be able to completely change the structure of the military territory.
But even then, it was not as if that was their real intention. Instead, they just wanted to make sure that the territory was quite stable, before they went back to Trista territory.
