Only the girl's heart, lungs, breasts and head remained intact now, and Sil stared at her new creation and again slapped her. "No talking," she intoned in that soulless voice.  A robotic arm whirred as a hand transformed into a vicious series of blades that began to spin. She braced her other hand on the back of Cassie's neck and the spinning blades quickly chewed through her Chest and ribs, turning her heart and lungs into a bloody pulp, blood and viscera splattering everywhere before depositing another module like the one that had transformed her lower torso. As the soulless robotic hand pulled away, a mechanical heart began to beat nd equally-mechanical lungs began to cycle. Then the 'skin' closed in on itself, replaced by that memetic substance  swelling her breasts to a size that about rivaled her head.
