The ease was too great. Leonel had a half foot radius around his body in which his Starry Spirit Domain could function without activating his bloodline. All he needed to do was touch something, and so long as it was compact enough, it would functionally, for all intents and purposes, be within his Dream World. And once that happened, everything was fair game.
Leonel no longer had to consciously use Dream Sculpt to transfer something into his Dream World now. This saved him time, effort and stamina. On top of this, he was also able to copy things that would have usually been far beyond his means in the past as well.
All that was left now was to organize them, and that was where Dream Unify came into being.
