Boom! Boom! Boom!
Countless blazing fireballs shot out, deeply burying themselves into the insect cloud before explosively detonating.
In an instant, myriad white flames rapidly spread throughout the insect cloud, igniting vast swathes of it into huge flames that illuminated the dark skies around.
After this extreme outburst, the brightness of the defensive light shield quickly dimmed, beginning to flicker unsteadily.
Although this strike cleared out most of the insects, Zhao Sheng knew it was only a temporary solution, not a cure.
Sooner rather than later, the demon insect tide would return, as the Southern Border's Gu Worms could never be completely eradicated.
As for using a formation to block the incoming insect cloud, Zhao Sheng had never even considered it.
