"Can you tell me how you modified your spell? Or maybe you found a book containing a modified [Shadow Bind] spell..." Frels asked him with an icy tone as she looked at the black spikes that were trying to pierce her body.
She raised her other hand and pinched one of the black spikes. The black spike broke into tiny pieces as soon as she pinched it.
"This one is not a modified spell. So I think that you only found a book containing a modified [Shadow Bind] spell as you are too young to modify a spell on your own." She commented and glanced at Souta.
"Grrr..."
Souta grabbed her hand and tried to push Frels away, but she was too strong for him. He silently cast the [Agility Boost] and [Strength Boost] spells. He also activated the [Cat's Speed] and [Triple Muscle Strengthening] combat arts.
