"Energy Shortage"

This was why, the status of monsters had always been the lowest in the eyes of many creatures, and for beasts to mutate into monsters because of miasma, many beasts would rather die as a beast before they turned into monsters. 

Seeing that the plan worked well and the number of beasts and monsters in the distance continued to dwindle due to the various aftermath of the disaster, Ainsley and the others sighed in relief. 

"It seems that it's okay to survive for a few hours...but I don't know about the demons." 

Ainsley looked at the 3D map once again and felt that even with the help of the holy Phoenix, somehow, more and more demons came out in various dimensional holes, and now, their number had soared instead of declining. 

The beasts and monsters could be dealt with using natural disasters, but demons just would not die unless they were hit by specific attacks.
