A sharp, unusual whistling sound came faintly, and moments later, Wales heard a thunderous boom rising from the plains to the south.
This was a sound that had never appeared in previous battles, one that the Crystal Cluster Giants had never made.
He raised his head, looking towards the direction of the boom, but could only vaguely see a huge plume of smoke rising into the sky, and near the area where the smoke was rising, the Crystal Cluster Army seemed to be in chaos.
It was said that the magic weapons made by the Cecil Clan could launch attacks from several kilometers away, projecting powerful explosive devices to precise locations, and before the arrival of this 'Skyfire', that sharp whistling sound was its most notable feature.
Reinforcements were entering the battlefield—but they were still far off.
