Looking back though, he found he couldn't see Ree Shil anymore.
In fact, at this moment, Ree Shil was experiencing the same thing. As he entered, his vision was obscured by the fog, causing him to lose sight of Exterminator Thirteen.
This mysterious fog was weird, not only isolating sounds but also making visibility different from outside.
In here, Ree Shil couldn't even see the Zombie Beast Hound 5 meters away from him.
However, they had telepathy between them, so they weren't afraid of getting lost.
"Well, since I am already here, let's explore."
From the outside, the valley didn't seem very large, so Ree Shil decided to use the Zombie Beast Hound to scout the way.
He wanted to deal with the demon monster first.
[Woof!]
That was the report the Zombie Beast Hound sent him. The scent of Exterminator Thirteen was getting further away, so it seemed like he wanted to deal with the demon monster first as well.
Unfortunately, he chose the wrong direction.
