"Beautiful!" Ling Yun exclaimed in admiration; even Zhao Yao and Tang Liqin were mesmerized by the beauty of the subspace.
Xiao Yin immediately warned them. [However, you guys cannot go outside the barrier for now, for this subspace is truly outer space, and there is no air outside. Even so, you can go outside the barrier once your cultivation reaches the Five God Realms.]
"Then how do we get in and out of this place?"
Xiao Yin pressed a button, and a box in the corner opened. There were dozens of rings inside it, and she explained it to him. [You can use one of those rings, Master. You can enter and exit this fortress freely using it, and only its owner can use it.]
Ling Yun went to the box and took out one ring, which he put directly on his ring finger. However, something stabbed his finger, and a notification that he was the owner of the ring appeared in his mind. "En, this ring is really good."
