[Alright, here's the deal. It is pretty obvious how powerful is the Gravitational Pull of those pieces. If you simply take them into your bodies, you will be dead. To absorb those pieces, you will have to break them into their most basic elements. Only then can you bring those elements into your bodies.]
Rean and Roan nodded. "And how do we do it?"
[The boring and painful way,] Sister Orb explained. [Use your Sky Energy and Blood Essence to slowly refine those pieces. All of that while keeping yourselves in close proximity to the pieces. That is part of the process to bring your two bodies to the next level. Don't expect it to be over in a moment. It will definitely take several weeks of painful work.]
"Several weeks?!" Rean was taken aback. "We could barely keep near such gravitational pull for a few minutes! How do you expect us to resist these pieces' gravity?"
