In a few minutes, Kai and Muchen reached a cultivation room. The area where the cultivation room was located was vast, spanning thousands of kilometers or more. Its breadth was equally impressive.
"Choose one and studyin it while I do something else. Tap this tag when you are done," Muchen said, throwing a tag at Kai. Catching it, Kai nodded and walked up to the cultivation room.
Using his perception, he scanned the area and found no one there. Muchen had already disappeared.
Kai sighed and entered the cultivation room.
There was no difference between the immortal Qi outside and inside this room. Just then, the back opened.
"A pocket dimension?" Kai thought as he walked to the back. Outside was a small island.
Entering it, Kai was hit with a massive surge of immortal Qi.
