Chu Zhou, Rambo, Longyue, He Yu, Ai Tuo'er, Saffy, and the others looked up at the gray fog surging in the Starry Sky.
In that expanse of the starry sky, there was a faintly discernible incomparably enormous black mountain that entered their eyes.
The black mountain was too tall. When he looked up, he could not see the top at all. It was as if it had cut through the entire Starry Sky.
"This is the Black Mountain Secret Realm." Wuka pointed at the Black Mountain that was mostly hidden in the gray fog and said, "Every once in a while, the gray fog surrounding the Black Mountain Secret Realm will disperse. This is the best time for you to enter the Black Mountain Secret Realm."
"Last warning: When you enter the Black Mountain Mystic Realm, you must be on high alert. Don't fall into the strange gray fog… Otherwise, you might never come back."
After saying that, Wuka stood together with a few staff members and did not speak anymore.
