[However, we finally discovered an unusual place. In a valley, there is always a thick fog, and it seems to spread over time, covering a large area.]
[These fogs are not as thin as in the valley, and they don't seem to hinder people. At most, some hunters who want to hunt in the mountains get lost and seem to be trapped.]
[After analyzing this, you finally decided to go and check it out, as staying in the Imperial Palace wouldn't help in unveiling the truth.]
[When you arrived at Fog Mount, you used your Spiritual Sense to cover the area and examine the inside of the mountain. To your astonishment, your Spiritual Sense as a Profound Elixir Realm master was blocked by the fog.]
[You all thought this was very unusual since the power level of this world is not high, so there shouldn't be anything that could block a Profound Elixir Realm Cultivator's Spiritual Sense completely.]
