Thanks to Kaleisa's explanation, Yang Ling soon gained a basic understanding of the situation.
As it turned out, the Nine Phantom Mountain Range was situated at the most western point in the Chaos Dimension, spanning millions, if not billions, of miles. Other than the high and mighty Core Deities or powerful fighters like the Dimensional Wanderers, not many people would know just how large the area was. It was covered with towering mountains, some with extraordinarily high peaks, making the terrain there extremely hazardous. Many of the areas there were perpetually blanketed in fog and had abnormal levels of gravity. Even a Divine Duty Expert would have trouble flying directly into the area.
