Victor was so busy using every ounce of his power and strength to dodge Bill's final attack that he didn't even notice Erin and Nathan's loud footsteps as they approached him from behind, shocked by the scene they saw in front of them.
The once narrow tunnel was no more as now it felt like they had entered a large room that was full of debris and broken rock with two strong forces battling in the center.
It was too hard to make out what was happening with Nathan only being able to sense what the two of them were doing as even his perception was not high enough to actually witness the speed at which the two of them were clashing.
"He's a coward.." Nathan as he realized what was actually happening.
All the fierce and massive attacks that were completely covering the center of the tunnel were actually just Bill unleashing all of his power to destroy Victor, with Victor doing nothing but dodging as his life literally depended on his famous ability to dodge and evade.
