The magic barrier that the demon commander had released was one that used all of the remaining mana that he had.
He didn't hesitate in doing this since he remembered what had happened last time when he took a hit from this strange looking sword.
But the problem was…even magic barriers weren't a problem for The Penetrator.
Whether it was magic or not, The Penetrator didn't have a problem penetrating through it with its 99% penetration stat.
So the magic barrier wasn't able to resist for a single second as The Penetrator smashed right through it.
The demon commander clearly didn't expect this to happen since he hadn't moved at all after putting up the barrier.
From the very beginning, he was filled with confidence that he would be able to take care of Cecilia and the rest of the elves once he had activated his trump card. That was a trump card that would threaten his life if he used it too much, which showed just how powerful it was.
