How did I do and observe all of that?

'I'm going to abuse this bullshit to the limits,' Mathew thought when a second shockwave for the day turned the crowd of the zombies into a splatter.

The zombies behind and to Mathew's sides had it the easiest. The moment the wave of compressed air struck them at a great speed, some would be simply knocked away. A lot of the zombies that already bore the injuries from the earlier fights or even from when the original owners of the bodies died would fall apart under the condensed gust of wind.

The zombies that had it the worst, were those that were within a certain range and at a certain angle towards Mathew.

Tsssz!

At least a hundred zombies happened to stand in the kill zone. It was marked by painting a huge circle on the ground with Mathew in the middle and designed by a radius of how far his skill could push the zombies away.
