This place didn't seem to be inside a mountain cave at all, but rather as though through that cave, one had blinked and arrived in another realm.
An eerie yin energy was constantly spreading around, shrouding the entire area in a layer of white mist. This thick white mist was in fact yin energy that had become so dense it had materialized!
Liu Feng felt his whole body was very cold.
He thought that if he had not been a cultivator, he might have fallen ill just from the gusts of yin energy.
But even though he was just barely a cultivator, in this environment dense with yin energy, he still found it somewhat unbearable.
It made him shiver uncontrollably.
Even his eyelashes were coated with a layer of ice crystals.
"Good... goodness..." Liu Feng's voice trembled as he muttered to himself, "What on earth is this place, and what is a Witch Immortal's lair?"
His subconscious told him that he had come to an incredibly formidable place.
And in his mind, it was as if a voice.
