Everyone was startled.
However, none of those present acted, as the gunshot came from outside.
Outside the airport, countless zombies surged frenziedly, dense and seemingly endless.
There was a car in front of the zombies.
The zombies, moving at an extremely fast pace, pounced on the side of the car and crawled onto its roof.
The sound of bullets sweeping through the air continued above the airport, creating an apocalyptic scene with the groans of the zombies.
A shooter firing from the car window was grabbed and pulled out by the zombies.
In an instant, the car was overwhelmed by the zombies.
The zombies surged toward them like a tide.
"Retreat!"
"Quick, retreat!!"
The people who came to their senses roared in anger.
On the other side, Miss Chuzheng and the others had already gotten into a car, which had now started and was speeding away to the other end of the airport.
The people: "..."
