We entered the dungeon with five people but leave with seven. Including the Giant King and the giant whose finger I cut. That giant is carrying the Giant King on his back after Primo cast shrinking magic to shrink them into human size and also used transformation magic so no one will recognize them.
The Dungeon Break for this dungeon has happened a long time ago. It's just that the Giant King was restricted and his limbs were cut so he couldn't do anything. He couldn't leave.
It means that we don't have to wait until Dungeon Break happens. We can just leave with the Giant King. Except for Silva who will stay behind after we left first because he will destroy the Dungeon Core.
We don't know yet if a giant in a dungeon where Dungeon Break has happened will be able to escape if the core is destroyed. That's why Silva will stay behind.
