"Since we've already mentioned the Charm to Repel Weapons..." Vizet's gaze turned to Ron. "Ron, we should move on to the next stage of the demonstration."
Ron took a deep breath, nodded hard, and answered firmly, "All right!"
He raised his wand upright in front of him and slowly closed his eyes.
As his eyes closed, his expression gradually calmed. His earlier excitement faded completely, replaced by focused determination.
"Averte Telum!" he chanted in a low, forceful voice, swinging his wand forward and tracing a casting path similar to the Patronus Charm.
A faint golden halo spread out from his body, enveloping him completely.
"Very good!" Vizet nodded approvingly, then explained to the students and guests, "One of the characteristics of the Charm to Repel Weapons is that it can move with the target chosen by the caster."
Ron began walking slowly in front of the students, demonstrating the effect of the Charm to Repel Weapons.
When he passed by the Gryffindor students' section, one student with a sly look on his face secretly picked up a paper ball and threw it at Ron.
The next moment, the paper ball was affected by an invisible force, veered off in another direction, and smacked another Gryffindor student on the head with a "pap."
"Ow!" The Gryffindor student jumped in fright, clutching his head and crying out involuntarily.
When the other Gryffindor students saw this, they burst into laughter.
Vizet took the opportunity to say, "Miss McDonald, Mr. Robbins, thank you for your participation."
"In some respects, the Charm to Repel Weapons is similar to the Patronus Charm. It can also exist for an extended period and produce its intended effect."
The student who had been hit by the paper ball widened her eyes in surprise when she heard Vizet say that.
