Rumble…rumble…
As the number of royal blue lightning bolts continued to gradually increase, they occupied more and more of the area previously occupied by the lavender lightning bolts. Concurrent to that, the dark clouds would let out a loud rumble from time to time, bringing forth a wave of destructive intent that was around half as strong as the wave that spread throughout the area when the first royal blue lightning bolt was formed.
Nevertheless, Argentum and Horell could not help but be on edge with every wave that passed through their body…well, mostly Horell. To Argentum, after sensing the arrogance that was inherent in the intent of the royal blue lightning bolts, he could not help but connect the frequent rumbling of the dark clouds to the arrogance of the royal blue lightning bolts. It was as if the lightning bolts were flexing their strength towards the trio.
