Jermine dug down till she hit a literal wall that Zero and Bob took turns analysing. It didn't feel like solidified sand rocks. In fact, the surface was so smooth that it surprised Zero. Who knew that underneath all that sand and sand rocks, there would be a rocky layer?
Mii did some research. While Jermine dug through and mined through the sand and broken rock layers, her claws were not strong enough to break metal or bedrock which was what Zero and Bob were working with. The monsters inside the underground cave were also not strong enough to break the thick wall of bedrock but more surprisingly, Mii concluded that this was no ordinary cave. It was a dungeon.
"Be careful," the strawcherry fairy warned as Zero and Bob progressed deeper. "This isn't a normal cave, it's most likely a desert dungeon. These rocks have been formed using magic over time and strengthened by feeding off mana from the creatures in the cave."
