Can the Sect Protection Array monitor the movements of demons in this world? Most likely, yes, since demons also gather Spiritual Qi, and the possibility of breeding Inner Demons can't be ruled out.
Maybe it won't keep an eye on small Mountain Demons or Earth Spirits, but for Great Demons like the Cyan Dragon Vortex, the array should remain vigilant.
However, the array's focus should not be limited to this alone.
There is a resource that is the core asset of the Lotus Cloud Sect: the civilians living in this world.
According to Ji Lian's concept, she has to guard against survivors banding together to form organizations similar to the Immortal Alliance, accelerating the breakthrough efficiency of cultivators, and also prevent them from being massively slaughtered by demons or from internal wars becoming too disastrous, leading to rapid population decline.
After all, the existence of the Pocket World is to provide a place for humanity to survive.
