Before Gao Haoyun, Du Kunsheng had heard that zombies had successfully broken the base, and ordered his subordinates to bring most of the survivors into the underground base which was located twenty meters under the ground.
At that moment, he himself was moving speedily toward the broken part of the fence wall, along with a snowstorm. Icy cold, the fierce wind hit the fence wall along with heavy snow and blew off the zombies which had climbed on top of the wall.
The snow reduced the visibility in that area. Nothing could be seen clearly except the heavy snow, and the cold wind made people's scalps numb.
Du Kunsheng's wind and snow power didn't affect zombies strongly. The best he could do was blow those zombies off the fence wall without being able to freeze them. He also made the surrounding superpowered people shiver in coldness and slow down.
But still, the zombie invasion was stopped effectively.
