Constantly evolving zombies

Faced with the endless wave of bullets, the zombies were slowly beginning to fall. However, it was simply impossible for thirty inexperienced people to annihilate more than four hundred enemies who felt no pain and did not fear death when the distance separating them was only about a hundred meters.

"Cease fire! Retreat one hundred meters!" Bai Zemin commanded deeply as the zombies approached fifty meters in front of them.

The militants turned pale as a sheet when they saw for the first time in a long time so many zombies from such a close distance. Upon receiving Bai Zemin's direct order, those who could barely contain the urge to flee as they remembered the consequences immediately turned around and began to run in disorderly fashion toward the second line of defense marked in advance.

Seeing how disorderly the retreat was, Bai Zemin sighed secretly and also retreated after making sure that all the men had reached a safe point.
