"Activating The Sky Array"

When the old general saw that the aerial enemies were already here, he immediately commanded all the rooftop groups to focus on these 200 aerial enemies. 

"Everyone, focus on the aerial targets! We have to wipe them out before they can launch any attacks!" 

There was almost no obstruction blocking these aerial enemies, unlike the case in the forest, so these enemies could also attack the castle way easier than the forest's force. 

Even if there were at least 300 people on the three rooftops, and they outnumbered the aerial enemies, the aerial enemies could use their abilities faster than the ones in the forest due to their height advantage. 

It was easier for the enemy's attacks to arrive first before the rooftop fighters could land a blow on these aerial creatures. 

It seemed that the aerial fight would be more troublesome than the forest battle! 

The rooftop fighters were all prepared, but the aerial force was also prepared.
