Bab 988: A Frozen Heart is a Good Heart.

"Well, I can't study the heart while being here." Lady Sphinx disclosed.

There was no access to Queen Ai to help them scan Imyr's heart and create a close virtual copy of it.

Felix shouldn't take the heart to her since he would lose out decades of time inside the dimensional pocket by being merely a few months on the outside.

"How about you use Felix for research?" Thor suggested, "He has a research lab as well, and he is smart enough to follow your orders."

"I am not talking about that." Lady Sphinx shook her head, "For such difficult project, I need to have perfect copies of the heart and subject's body. I can only do so with my sand manipulation."

Lady Sphinx's research prowess was heavily reliant on her sand abilities.

It allowed her to explore all options with extreme precision and without worrying about losing either the subject or the object.
