Generally speaking, a single Dust Cleansing Pill was enough to cleanse away the aura of the Lower Realm from Shen Long, and the extra four Dust Cleansing Pills were for feeding the Spirit Beasts. Any beings that ascend from the Lower Realm to the Realm of the Spiritual Pivot had to cleanse away the Lower Realm's aura; otherwise, they would face minor heavenly tribulations every hundred years and major heavenly tribulations every thousand years.
According to Lin Huahua's introduction, Monster Beasts of the Lower Realm that cultivate to the middle stage of the fifth rank can also ascend to the Realm of the Spiritual Pivot. They are often taken as Spirit Beasts by the Cultivators guarding the Ascendant Platform or killed by Cultivators.
