An invisible ripple appeared in the air and simultaneously, the black tide also rushed into the invisible ripple.
Bang!
The two forces collided and the barrier shook, almost shattering before it could even fully envelope the whole area.
Some insects in the black tide perished on the spot but compared to the number of those still alive, it was just a drop in the ocean.
Bzzzztttt!!
The black tide rammed themselves into the barrier and instinctively flew towards the area not yet covered by the barrier.
In Castra's eyes, the black tide seemed to "chase" after the barrier that was quickly enveloping everyone, including him and Mario's family members.
Some insects inevitably flew faster, seeping inside before the barrier could form.
The moment some insects breached the barrier, the instructors in those areas immediately launched a collective attack!
"All students! Gather in groups of five! Don't scatter! Don't scatter!"
"Protect yourselves!"
