The good thing about all of this was that all the leaders themselves were united for the same cause. Even if their elders are divided, with the leaders on their side, it wasn't that hard for Krune to finish transferring all the leaders' links into their own Organizations' Cores.
Of course, they also asked Krune to transfer more of their members into the same core so that they could go out together. However, Krune blatantly rejected the idea.
"Out of the question. Our Planet outside has no Nascent Soul Realm expert. If I make it possible for all your God Core Realm experts to leave this place unscratched, what will happen to the powers outside? There are enough God Core Realms here to take control of any big power there. I will make it so that the four of you can leave. However, no other God Core Realm will receive this treatment. Even if you kill me, I will still not do it."
