Around the Netherworld Ghost Cave, there was an extremely high concentration of Yin energy, and in the place near it, the black energy was exceptionally profound. That was Netherworld Energy.
Ordinary strong people could hardly approach, so usually, no one would step into this Netherworld Ghost Cave.
However, at this moment, strands of Yin energy had gathered around the Netherworld Ghost Cave, seemingly forming a passage leading directly to the cave, while the other end of the passage extended outward, all the way beyond this polar region.
"The Netherworld Ghost Cave is about to open."
Ye Xuan withdrew his gaze, then showed a contemplative look. As long as this passage solidified and stabilized, it would be the best time to enter the Netherworld Ghost Cave.
