The effect of the fire wall was quite obvious, blocking the gnolls' attack.
But this was just delaying the inevitable, and wouldn't injure the gnolls.
As gnolls kept pouring in from the east side gap, the pressure on the adventurers and the garrison kept rising.
But the fire wall at least created a relatively narrow and confined space, making the gnolls unable to swarm them.
In these kinds of circumstances, humans had the advantage due to being stronger.
Gru, as the captain of the bramble team, was naturally very talented.
He blocked most of the frontline by himself, each swing of his great sword ending two or more gnolls!
His strength was quite astonishing!
The other adventurers were also doing their own parts.
They all had their own skills. It might be hard to display on the battlefield, but this kind of small area would actually maximize their abilities.
This was something Marvin had thought about.
