"Creating A Blizzard" 

After all, the sky route was freer than the land route due to various reasons. 

It was just that, these sky beasts and monsters that had already entered the range of the field yet still wanted to retreat could not escape as easily as before. 

Even if they wanted to escape, the fierce tornadoes had already blown away countless sky beasts and monsters. 

The rain was somewhat strange as it was mixed with acid and such, adding insult to injury. 

This thunderstorm field was really so terrible that many sky beasts and monsters fell from the sky directly to their death. 

A lot of beasts and monsters didn't die due to the direct attacks of these elements, and they actually died because they could not fly anymore, broke their wings or something, and then they died a tragic death after falling to the ground.
