The flames rained down on the demons that wanted to go and help the demons with corrupted energy.
The demons could only stop and raise their defenses, but the flames that rained down were powerful.
There were many demons that were burnt to a crisp because of the flames that rained down on them.
Even if they were powerful demons, the flames were more powerful than them that they couldn't resist it at all.
As for why the flames were so powerful…
There were wyverns that suddenly appeared in the sky.
When these wyverns appeared, the king and generals of the Poppin Kingdom immediately knew who were the ones that came to their rescue.
Their Poppin Kingdom was one of the kingdoms that was second only to the four empires, so the information network that they had established definitely wasn't weak. This information network obtained information for them from all over the continent.
