Upon hearing the words, Fang Jie immediately concealed his aura and rushed forward.
Moments later, Fang Jie arrived at the circular mountain. To call it a circular mountain wasn't quite accurate—it was more like a gigantic basin. The mountain's height reached over 20,000 meters, which was considered quite tall in this world.
The interior space was even more vast, approximately the size of an entire kingdom.
As Fang Jie glanced inside, he noticed that the area was almost entirely filled with demon creatures.
There was an exit at the front of the circular mountain, but it likely wasn't naturally formed, rather it had been created by the demons. After all, without an exit, it wouldn't be convenient for them to move out in large numbers.
Further inside at the center of the mountain range, there was a volcano. The volcano continuously erupted molten lava, as if it was perpetually erupting. Of course, that was essentially the effect.
