Mikey shook his head. "Permanently? Feh, It's hard enough to seal it temporarily without outright cutting somebody's arm off. In order to seal it permanently, you'd probably need to seal the network off at the spinal cord with an insane amount of focused Ki. Even my pops couldn't do that, though... And don't worry about healing. I'll heal you, assuming you survive. You just gotta win, haha."
