Although the Fire Bullets were powerful enough to easily pass through the Ice Walls, they weren't powerful enough to completely shatter them. So, Femradiel had the chance to create some concentrated Ice Bullets and cancel the Fire Bullets.
Ryan really felt proud of himself for coming up with that idea. Whatever happens now, neither of them will be able to complain about the result, which was indeed a contest of skill. Still, Ryan couldn't help but worry that Femradiel might go a bit overboard and use her reserves of mana to go all-out and win. The mana she had been saving to create a new body.
Ryan's predictions came true much sooner than he had imagined. Femradiel began to condense her mana in several points around her. Those points turned into invisible machine guns that fired endless Ice Bullets.
"Femradiel…" Ryan facepalmed.
