A giant bullet descended into the room. The bullet was a bit longer than Saskia was tall, and somewhat fatter than a beer keg. It was machined aluminum in some places, carbon fiber in others. It had a Flying S logo and was stenciled "RETURN TO FLYING S RANCH - REWARD" in English and Spanish. It glided down past them on the hoist and was seized by a massive robot arm, which pulled it away, indexed around, and fed it point-first into the base of one of the gun barrels. Another mechanism, pushing up from below, then rammed the shell upward until it had completely disappeared into the barrel. Something went kerchunk. The robot arm retracted, but the shell did not fall out.
