One of the C-rank chambers in the Dark Baneful Aura cave at Myriad Wither Peak.
"Lord Meng Chuan, please," said a steward respectfully as he pushed open the stone door.
Meng Chuan nodded and entered the Dark Baneful Aura Cave.
The Dark Baneful Aura Cave required fifty credits every two hours. This was because the Dark baneful aura was rare. It was useful for many Godfiends. If one cultivated in an A-rank chamber, they would need 5000 credits for two hours. However, the baneful aura density in an A-rank chamber was far beyond what a mortal could withstand.
Even in the C-rank chamber, many geniuses' minds would turn into a mess when the baneful aura attacked their minds.
It's really cold. Meng Chuan entered the chamber and closed the door. A faint black fog—the Dark baneful aura—filled the chamber. A cup of hot water would turn to ice before it could hit the ground.
