In The Zombie Shadows Chapter 35

The fog on the lake became thicker and thicker, and zombies gradually entered the lake and gathered in the center of the lake where Gu Xuan was.

After a violent roar, the lake boiled again, the dark red wings retracted, and the slender figure plunged into the center of the lake. The water in the lake suddenly surged, and the zombies stood motionless in the water until they were submerged.

In the evening, the fog gradually dissipated, and the sky above the lake was empty. It was as if Gu Xuan and the evolved zombies had never appeared. The remains of the alien beast remained at the edge of the lake, but were soon dragged away by scavengers and disappeared behind dense tall grass.

Only a few pools of dried blood were left on the ground, becoming the only evidence that the corpses had ever appeared.

Gu Xuan left District 11 and took away most of the high-level zombies.
