"The Last Abyss Gate Is Open" 

Those few seconds were enough for the nearby monsters and beasts to launch their attacks and then hit the people behind the barrier. 

The battle had been going on for an hour, and there were already two waves of attack from the beasts and monsters around. 

This batch alone was actually just a group of beasts and monsters who were distracted and didn't run away or go berserk in the same direction as the huge tide. 

The real beast and the monster tide had a few  hundred thousand monsters and beasts, which was enough to drown everyone even if they had five-layered barriers, arrays and the blood dome. 

Ainsley's blood dome only protected the rooftop before, so when there were holes in the barrier outside of the castle, there would still be some students and contestants being injured.
