Krune could have waited until he was somewhere else. But Feifei asked him to absorb it here in case there was a problem with the Heavenly Fragment.
Krune's Heavenly Fragments, which had already fused together, felt the presence of the new Fragment. Immediately, both sides began to resonate with each other. As always, the Ownerless Heavenly Fragment tried to resist. But because it didn't have support from its own Universe anymore, it couldn't fight against Krune's Fragments.
However, the liquefication that Krune was expecting didn't happen. Usually, his own fragments and the new one would turn into some kind of liquid before fusing together. After that, they would solidify in the form of a core. It's just that the core would have a crack since it wasn't complete. However, it didn't matter how long Krune waited. In the end, neither side turned into that.
