The robot that just lost his arm seemed unfazed. He cut a slightly bigger section of the little of what remained of his own arm, causing it to fall down. Roan's Dark Element was still there, and it quickly corroded it. Following that, the earth below the robots seemed to stir; some kind of material floated from the ground to the now empty place where the robot's arm was before. Finally, Rean and Roan saw how a new arm quickly grew up... or, to be more specific, how it rebuilt itself.
The robot glared at Roan and then at Qwerty, who was being held by Rean. Then, he commanded. "What are all of you looking at? Attack! Take our HAF100 back!"
Sure enough, all the robots attacked again, but they ignored the sect's experts, who were pressed to the ground. They all focused on the twins since they seemed to be the only ones who could move.
