Invisible Rock Attacks!

"No danger?" 

Merlin did not believe it. Just a moment ago, he felt a violent surge of danger. If he had not taken the opportunity to escape, something unbeknownst might have occurred. 

That surge of danger came very quickly, without any hint of premonition. Hence, Merlin glared unblinkingly at the Progenitor's Bodies on the battlefield but he did not discover anything out of the ordinary. 

Nevertheless, the combination of Lach and Merlin managed to land a surprise attack on one Progenitor's Body. About a dozen Ancestor-level Rock Creatures in it died, so it was a huge loss to the Rock Tribe. In contrast, it was a large victory dance for the Spell Casters. 

"Merlin again!"
