Although they had successfully knocked down Earl Yury, they were still trapped within this magical barrier.
Theoretically, as long as one had sufficient power... it should also be possible to shatter the barrier. This is what is meant by "force can bring a breakthrough."
But seeing Earl Yury, who was hit by the "Departure from the Abandoned Station," bounce high up and then get bounced back directly when he struck the barrier, as if hitting the edge of a board, without the barrier even shaking... one could tell the strength of this barrier.
Annan had originally wanted to use the "Tyrant's" triple amplification, by hurting himself until he was critically wounded, and then release a Brilliant Sword to directly blast the barrier apart.
But Jacob's words persuaded him.
