After Philip Grace asked, Michelle explained how she extracted Life Stones from monsters.
She did it in a rather straightforward way.
Once a monster died, she would use a sharp object to cut the skin and flesh surrounding the Life Stone to expose the bone.
Once the white of it could be seen, Michelle would crash her spirit energy or soul energy into the bone to shatter it.
Once that was done, she would dig either with her hand or something else into the hole created, pushing through the brain matter until she could be sure her hand was under the Life Stone.
Like that, she would finally pull it out along with the gore around it.
That also let her discover that not only were the Life Stones lodged into the monsters' skulls, but they also went through and were connected to the brain.
Quite the interesting find, actually.
So, with the Life Stone extracted like that, Michelle would just need to rid it of the brain matter and bones stuck to it.
