The Alliance Army didn't attack the exotic beast sect right away. Their Army had yet to adjust, so they had been staying in the camp. From time to time, they would come out to practice, but not for anything. They just had the people from the various sects fight together, and didn't get into any formations.
The exotic beast sect was also training. After all, tuli and the others had only been here for a short time, and the exotic beast sect had never undergone any military training before.
However, both sides knew that they did not have much time to prepare. The Alliance Army was very clear that every day they stopped here, they would be exhausted by another day. Furthermore, the exotic beast sect would not let them stay there and train quietly. Just because they did not attack the exotic beast sect did not mean that the exotic beast sect would attack them. Therefore, they were even more careful now.
