The monster dashed at Xander, this time, with twice the amount of speed as before, it's target being the small low leveled creature in front of it.
Xander looked forward, the fly monster was already too close to him, there was no way to dodge it, it was too big.
Just as Xander gave up the shadows around the bug moved and a transparent dark pillar rose out of the floor in front of Xander, blocking the attack.
The creature let out a loud, ear piercing shriek that echoed in the tunnels as it collided with the pillar. It didn't even have time to recalibrate as a giant flat, sword looking shadow erected from below the fly and pierced through it from below, killing it.
Xander was surprised. He stared at the creature as it's big body fell to the ground with a thud, lifeless, dead.
Xander's eye shifted from the giant dead fly to the person standing beside it, Harry, who had a sad and solemn look on his face.
