When they entered, what princes and princesses saw surprised them. They were in a giant xenogeneic's mouth.
After it was confirmed, they discovered it was the mouth of a dead xenogeneic's skeleton. They were inside the skull's mouth.
The giant xenogeneic's skeleton looked like the bones of dinosaurs. There were wings on its back, but only the bones of its former appearance remained.
On the ground below the xenogeneic's bones, everything appeared petrified. The surface was very rough. There were many carvings on the bones. There were symbols and lines. There were weird crystals on the symbols and lines.
"This is the true space demon dragon," Bai Kanglang said while staring at the bones.
