Chu Feng completely understood.
The energy in the Spiritual Abode was poor. Perhaps it was because the owner of this Spiritual Abode was only a Seventh-Turn Heaven Martial Realm expert!
It had just been established and had yet to be filled.
When this small space was filled, the master of the Spiritual Abode would be considered a Ninth-Turn Heaven Martial Artist!
The size of the Spiritual Abode represented the potential of a warrior.
The space in a first-grade Spiritual Abode was the smallest, and the space in a ninth-grade Spiritual Abode was the largest.
This might be the reason for the difference in grades.
Of course, this might only be the simplest difference between Spiritual Abodes.
In other aspects, there would definitely be a huge difference. The higher the grade of the Spiritual Abode, the more miraculous it would be!
