When the mummy guards reached that hole and were about to stab out with their spears, they found that there was something that was flying towards them.
They immediately stopped moving forward and raised their spears to spin around in an attempt to block the things coming at them.
This was a wave of arrows that had suddenly been shot from the back of the formation.
Until now, the bows hadn't been used as much during the fight.
There were only a few arrows that came out from time to time since they had been fighting in close range. If they used the arrows, they might have harmed their allies instead of hurting the enemy.
Only now did a wave of arrows come out like this.
That was because the enemies had been gathered in a single spot for them to shoot.
It was impossible for them to miss like this.
Though they attempted to use the spears to knock down the arrows, they weren't able to get them all in the end.
