It seemed like the 3 Dark Evil Cults had turned their attention to any alternative escape routes and locations, and one of those had been the newly found Secret Realm.
This Secret Realm was recorded as the deathbed of a strong expert that had reached the peaks of cultivation, and they were expecting a lot of good things from here.
The fact that this place only allowed for experts of the Great Ascension Realm and below made things trickier, but it was nonetheless a good escape route for their Young Generation.
The Core Disciples were made to lead the Young Generation experts in order to make sure that they settled properly in here, while the Guardians were to provide help and stability.
After all, no matter what situation was found on the Secret Realm, they would need power and strength to make a place for themselves.
