What are they trying to do?
Qi Xiangyun, having encountered some mythological tales from other worlds, believed that what those people wanted was to gather the world's fortune to create a place similar to a 'Heavenly Court'.
Those people from the Immortal Realm probably wanted to become the Supreme Demons of a new era.
In the past, when Supreme Demons existed, they only dared to stay hidden and not come out. If they wanted to become the Supreme Demons of a new era and make a move against the Supreme Demons, Qi Xiangyun wouldn't look down on the Immortal Realm people for doing so.
The result, however, was that they took advantage of the disaster's end, picking peaches before the world was stabilized...
If that's the case, then the Immortal Realm really has no need to exist. Since the Immortal Realm also gathered the unique fortune of her world, it would be better to destroy those Immortal Realms and bring blessings back to the Mortal Realm.
