At Yundao Peak and other locations where a small-scale Spirit Gathering Formation was set up, it would absorb the spiritual energy from other parts of Chengsheng Mountain, increasing the concentration of spiritual energy in the area of the formation to 180 points.
The concentration of spiritual energy at Chengdao Peak was even higher, reaching 420 points. Such a level of spiritual energy concentration could only be found in the dwellings occupied by the Ten Major Sects.
Of course, after those major sects used high-grade Spirit Gathering Formations, the concentration of spiritual energy would be even higher.
Just setting up eleven Spirit Gathering Formations had cost Han Mansion half of the Spirit Stones it had accumulated over many years, and that was the result of Han Li, who was a Seventh Grade Array Master, setting up the formations himself.
