Bab 856: Cap 854: Something is not right with this Dungeon

Pov of a Silver Grade Adventurer: 

"< Sea of Flames >" (I) 

"< Wrath of the Wind >" (Miura) 

"< Spatial Distortion >" (Khatori) 

We were on what was left of a floating island when an army of Celestial Harpies, they are 3 meters tall completely white Harpies that have wings on their backs and normal arms, wear white armor or white tunic, still have the legs of birds and their feathers are all golden. 

These annoying things have high physical, magical, and spiritual resistance. 

They are extremely difficult to kill and are still working together, the few surviving Bronze Grade Adventurers we brought died here, and many more died on the way here.
