The question was how he ought to go about gaining control over the energy and nutrients that his body obtained from the Hungry Pain technique. This was where the hard part began.
('The issue is that cells deal occurs uniformly across the body barring the brain,') He sighed. ('This makes it hard for me to gather all of it and channel it the way I want to.')
Had, for some reason, all the dead cells that the Hungry Pain technique recycled all been concentrated in one location conveniently, then there would have been no problem for Rui to come up with some way to control it as he pleased because it was so conveniently rounded up for him.
It would have just been a matter of engaging in some conditioning, both mental and physical.
But he wasn't sure how he could redirect all of the yield of Hungry Pain to whatever physical parameter he wanted.
