In this resource point, there are actually not that many Senior Beasts. The reason why the human mages were unable to wipe out the magic beasts was because of the countless Junior beasts.
Granted, the Junior beasts have limited strength, and Senior Mages can easily kill them; sometimes, quantity can create qualitative changes!
It would take a very long time for the Senior Mages to kill all of these Junior magic beasts, and while they do that, the Senior beasts wouldn't stand idly.
Even if the strength of the weaker beasts is not much, they win in numbers. They can still occupy the human mages and give time to the stronger magic beasts to launch attacks.
As such, the two sides were in a stalemate, yet it seems like that would change soon.
With Rezen's relentless effort, the number of Junior Beasts starts to dwindle. Even just waving his hand and throwing the modified Ghost Berries in the air has become tiring after doing it an uncountable number of times.
