Adrian knows what the Cube of Paradox is saying. It means that anything that it absorbs will also be integrated to Adrian's soul since the ego of the Cube of Paradox is a branch of his soul. Anything that the other would definitely benefit the other.
"Why can I not absorb it into my core?" Adrian asked the Cube of Paradox.
"Absorbing the bead via your core will be inefficient in utilizing the energies. It will take at least ten more years for the master to fully absorb it should you do that. Meanwhile, integrating it into my capabilities will make it more seamless.
I will also be the one that manages the energy that will be absorbed by the master to make sure that your soul will not be shocked. It is imperative that I would be the one to do this or the master will have to absorb the initial burst of the energy now which will take at least five days." The Cube of Paradox stated.
