"Guys, keep holding. A more powerful wind force will come and try to destroy everything. As all the elders already told us to use our full strength. Also, be careful about those earthquakes as they also contain Spiritual energy so naturally we need to protect the whole Kingdom from those earthquakes and those wind forces."
The leader of the Warriors told everyone to hold on to their ground as more impact would be coming toward them. Even though they did not go inside the danger zone and stayed outside of the kingdom, they could still feel the energy fluctuation that was created inside of the danger zone one after another.
As they had already been informed by the warrior association of what would happen with those Monsters. So they naturally can predict that most likely those Monsters begin to explode and all of these impacts get created by those explosions.
