At the bottom of the valley, black fog swirled.
This was Demon Fog!
Within the Demon Fog, even with the abilities of an Yinluo Sect Outer Disciple, one's vision was limited to a distance of about ten feet.
The Demon Fog was chillingly strange, flowing unpredictably. Faint wails echoed from within, seeming both real and illusory, disturbing the mind.
This Demon Fog emanated from the Nightmare Demon sealed at the bottom of the valley, and it naturally possessed the ability to attract Outer Celestial Demons!
Outer Celestial Demons would use this place as an anchor and medium to traverse the vast void and descend through the Demon Fog.
The twenty Outer Disciples were divided into four groups of five, each led by one of the four Outer Elders, and entered the valley floor.
Fang Cheng was assigned to Elder Lu Wei's group.
Elder Lu led her group of five, dropping one person off at each location to stand guard over a ten-li radius and search for Nightmare Grass within that area.
