Back then, Chen Fei piloted a "Big Mouth Monster" to approach and attack the black vortex cloud. If it weren't for another supernatural power user covering him with arrows, Chen Fei wouldn't have been able to recklessly weave through skyscrapers and directly charge beneath the vortex cloud to unleash carnage.
Since the vortex cloud appeared over the Africa Continent, some time has passed. The closer you get to the core of the vortex cloud, the more terrifyingly numerous the monsters become.
For every kilometer you approach, the difficulty index skyrockets.
If "Spatial Branding" were still available, deploying a full fleet of airships and releasing all combat units, clearing the way with "Element Annihilation Bombs," then this battle could still be within reach.
However... this was just Chen Xiao'er's fantasy!
He didn't consider that deploying an airship battle group might be akin to directly invading another nation's sovereignty.
