We have projectile weapons like that, but much bigger. They're loaded up with stones or metal bolts, like enormous crossbows.

[ The shape of Julie's weapon is different, but the concept isn't foreign to her. A crossbow is similar in many ways. She pays attention, watching Julie line up the shot and where she rests the butt of the gun. Swords don't exactly have a recoil, but momentum has to be accounted for, the force of the swing and the movement and the opponent's opposing force; again, Ciri can easily apply her understanding to this situation.

Honestly, it makes her curious.

She covers her ears as instructed, already having heard the bang from further way. It is even more unpleasant up close, and she winces a little, but she keeps her eyes open. ]

How long have you been practicing with this type of gun?

[ She asks when Julie finishes her round of shots. ]
