Bombardment

A large number of second-tier zombies rushed out of the cave, roaring. Just by listening to the sound, it made one's scalp tingle. There was a significant difference between these and ordinary zombies. Second-tier zombies not only had astonishing defensive capabilities but were also much faster. They surged out like a torrential flood, with incredible speed, resembling a group of ancient wild beasts, rushing towards Waldo and the others' position.

Waldo remained composed. He unleashed the firepower of the Gatling gun, pouring out a massive stream of bullets. However, even this couldn't truly stop the advance of the second-tier zombies. The difference between them and regular zombies was vast. If a lone survivor encountered them, it would be extremely dangerous.
