"Szzzz..."
A hazy humanoid silhouette slowly emerged by the side of Fang Tan, hissing like a snake.
Before it got near, the duo including Fang Tan felt a bone-piercing chill pressing into their bodies. Goosebumps popped up all over their skin.
A thick stench of demonic aura emanated across the ground, covering the entire area within it completely.
Extraordinarily, this aura was tightly contained within the area and did not leak out in the slightest.
"This... this is...!?" Fang Tan could feel his teeth clattering against each other. Such intense demonic aura pointed only to a Great Demon. There was no second possibility.
Demonic aura was a very peculiar entity. It looked like fog, but was actually something else. To humans, demonic aura was more like a unique hazy substance produced by mixing the scent of demons with energy radiating from them.
