Cap 204: Dungeon of the Undead Part: 2

We are in a big underground cave where there is only the tunnel behind us that leads outside and a big skull-shaped door in the cave wall in front of us. 

  This door appears to be made of some kind of iron in the shape of a silver and black skull. 

  "So this is the Dungeon of the Undead?"  (I) 

  "Yes, all we need to do is touch the gate and it will open, according to what Mari told me if no one enters or leaves the dungeon the gate closes again."  (Diana) 

  "Before I go in I want to know what you plan to do?"  (I) 

  "With the maps, we were studying yesterday we'll make it to floor number twenty today if we head straight for the stairs."  (I) 

  "I think we can go straight to floor number twenty, Vanessa can train fighting there as she doesn't have any very powerful monsters on those floors."  (Irius) 

  "She can even take advantage of these constant battles to get used to her body and powers."  (Kira)
