Mind Palace

Hao Xuan opened his eyes and returned to back the Beast world.

"I feel like the Mind palace is getting smaller by the day. At this rate, it will be full within a few weeks. I'll have to make some new ones as soon as possible," he mumbled thinking about the two giant 18-feet guys camping in his palace.

From the Elementary Realm to the Origin Realm, the physical body was refined bit by bit. And in the Spirit Realm, the soul was refined and cultivators would be able to increase the power of their souls and strengthen it much more.

Each stage of the Spirit realm would allow the cultivators to open another Mind palace, but their requirements were too stringent and most people would not be able to open more than three or four throughout the entire spirit realm.

One needed a heaven-defyingly powerful soul to be able to support all of the Mind Palaces.
