The Spirit Rock Peak, where the entire courtyard was located, was one of the few mountain peaks abundant in Spiritual Qi within the Jiuhua Sect.
Although it couldn't compare to the concentration of Spiritual Qi in the Cave Mansions of Golden Core Cultivators, it was more than double that of Chu Ning's Cave Mansion at Yanfeng.
The entire courtyard was enveloped in Spiritual Qi, dense as if covered by a white mist.
This was not a mist effect from an array; it was genuine Spiritual Qi.
Clearly, there was at least a Tier Three or higher Spirit Vein beneath this peak.
The only thing Chu Ning wasn't too satisfied with might be the array within this courtyard.
He had encountered many array restrictions over the years and could naturally discern this at a glance.
Neither the Gathering Spirit effect nor the defensive capability was as good as the array Cen Zijin had set up for him back then.
Fortunately, he had brought the entire set of array formation tools with him.
