Boom! Boom! Boom!
Just as the Mutated Peregrine Falcon King was contemplating, another unexpected event occurred.
Countless booming sounds suddenly erupted, not from underground, but from all directions.
Its wings trembled slightly, and the gravity device had no effect on it.
In an instant, it was in the sky.
With its exceptional vision, it could directly see the numerous elite zombies in the distance.
They were everywhere, with the largest number of zombies in the front.
Most of these zombies were huge in size.
Far surpassing ordinary humans, they were clearly power-type zombies.
And each giant zombie carried a small artillery platform on its back.
The booming sound came from this.
Shaun chose not to purchase cumbersome fortresses; their immobility would only make them easy targets.
The mutated beasts were charging, and they were extremely difficult to stop.
