Clone Alex was speechless because those people were fighting over his territory. Actually it was possible to take over other territories. If that person did not enter his territory over a period of time, then any one could take over that territory.
'Why did they need a territory?' It makes Alex confused. It's really a confusing thing for him because why would anyone need the territory for the competition.
So without doing anything he just silently listens to the person and sometime later he seems to understand why those people needed the territory. Actually the competition is called the Ranking competition.
The more you are able to rank high in this competition the more you will get rewarded. Not only that but in this competition the owner of a territory receives the territory bonus that is really useful in this competition. Because of this right now both of this group are fighting with each other for territory.
