As for the other two Fourth Rank Low Grade Offense-Defense Arrays, their uses were somewhat special.
Golden Winged Mountain was already sustaining two Fourth Rank Array Formations, making it difficult to establish another Fourth Rank grand array there.
As for Lingxiao Mountain, the former clan grounds, its mountain spirit vein was only at the False Nascent Soul level and its foundation was relatively weak. Sustaining the original Fourth Rank Mountain Protection Formation, along with the cultivation of the cultivators within the mountain, was already somewhat strenuous; it likewise could not accommodate another grand array.
Thus, only Ice Snow Valley, the clan grounds and a Fourth Rank spirit land, still had some surplus spiritual qi.
Moreover, this place was the foundation of the Ling Clan. Therefore, Ling Pengyun set one of the Fourth Rank grand arrays within it.
As for the remaining Fourth Rank grand array, Ling Pengyun established it within a Third Rank High Grade spirit land several miles away from Golden Winged Mountain, the Border Mountain.
In this way, judging by the range a Fourth Rank grand array could project over, once that array was activated, the defensive light screen it conjured could not only cover Golden Winged Mountain, but its attack methods could also extend all the way to Golden Winged Mountain.
More importantly, although that spirit land could only barely sustain the formation's activation at present, even requiring the aid of Spirit Stones, it possessed considerable potential.

At that time, standing watch and aiding one another with Golden Winged Mountain, it would surely turn this border region of the clan, near Demon Race territory, into a wall of bronze and iron.
The clan would also be
