This cave obviously suits dwarves and Kenu people.
For normal humans like Heine, and skeleton humans, just maintaining movement is a problem, let alone facing enemies after entering.
But the dark substance inside made him involuntarily think of the "Pitch-Black Dungeon" Huihui had mentioned before.
This place is located at the westernmost end of the Southern Mountains.
From its location, the cave very likely extends westward, connecting to the last Array at the bottom left corner of the "X".
"Have you discovered any abnormalities in the western forests?" he asked.
Tuba scratched his head, perplexed.
"The west? No… The eastern forests are where you stumble upon those with pointy ears. We're not allowed to go south, we used to play in the west as kids and we never saw anything abnormal… Though there is a mine."
"A mine?"
"Yes, a mine that was abandoned long ago and collapsed seven or eight years back… They'd be hitting a dead end even if they managed to crawl in."
