Crushing

The zombies appearing around were partly from the nearby suburban residential areas and partly from the urban area.

Roaring, they rushed forward.

If observed carefully, it would be noticed that the speed of these zombies had increased significantly compared to before.

The zombies in this world were gradually becoming stronger, evolving.

Perhaps, before long, ordinary zombies would evolve into second-level zombies, or even third-level zombies.

With time passing, their numbers would only increase.

This world was becoming increasingly dangerous!

"Be careful not to make any noise. Zombies will easily detect us if they hear any sound!"

"Quick, have you noticed the change in the zombies? They're getting faster and seem to be getting stronger!"

"Yes, indeed, they seem to be getting more powerful!"
