Fog-like Woman

Soon after, with the coordinated shouts of the few Dark Spellcasters, a circle of strange fog appeared around the zombies and skeletons. If the guards accidentally came into contact with the fog, their skin would begin to rot rapidly, and not even their bones were spared. As a few of the guards fell to the attack, the terrifying undead army tightened the circle around Steve and the group.

Deathly Poisonous Fog?

Seeing the black fog around the zombies and skeletons, Steve's Sword Saint guard swallowed hard. The Deathly Poisonous Fog was a high level magic spell of the dark element. It was clear that the Dark Spellcasters around them were all Great Spellcasters. Coupled with the handful of high level Dark Knights, the situation was far from good.

"Young master, I'll carry you out, quick!" After a moment's deliberation, the cloaked Sword Saint knew that they had to escape. He squatted down in front of Steve, clenching his teeth.
