Cap 633: Impossible to have a smooth trip part 1

The first day of traveling through the Poisonous Forest was smooth, we didn't encounter any aerial monsters and no monsters on the ground tried to attack us. 

When it was night we stopped in a cave that was already known to the Elves, as soon as we entered the cave that was hidden by an Illusory barrier, Joseph throws some silver coins in a magic circle near the entrance, then two barriers were activated, one was for defense and another for illusion. 

Inside the cave were some simple beds, a magic stone of light, and some chairs. 

I sit down on a chair and Hinata who was invisible sits on mine on my shoulders. 

"Don't you have a better place to sit?" (I) 

"No." (Hinata) 

Sigh 

"..." (I) 

Joseph is startled to see Hinata, but then he sits in another chair, sometimes he looks curiously at me and Hinata. 

"Is she a Ghost or a Wraith?" (Joseph)
