Watching the arrow crash against his tier 6 spell, Stanley was shocked by the power it had contained but he wasn't too worried.
Snapping his fingers, he started to edit his magic circle while it was under barrage.
After a very short pause, he smiled.
*PING!!
Shattering into dust, the partials reformed themselves into a different magic circle and sent the attack high into the sky.
Seeing this, Shiro had a look of disbelief on her face.
"Wait how????" Shiro asked.
To her knowledge, editing a magic circle while it was under attack was impossible. That was because the moment the integrity of the spell was broken, the attack would pierce it like nothing and strike towards the caster. The fact that her teacher had changed his spell during the activation was pure insanity.
