Immediately Helena said that, the girls went on to individually battle the guards.
Lydia's blue blade appeared in her hand, she then hurled it at one of the guards who only smirked at what she was about to do, since he didn't understand the kind of power that she possessed.
Swoosh!
The blade cut through the air at a great speed like an arrow towards the guard who quickly put out a thick shield that abruptly materialized from a powerful defensive spell that he casted.
However, the blade which was a weapon that always faded in and out of corporeality, turned insubstantial in the next moment and passed through the thick magical shield that the guard generated from the quick weaving of a defensive spell.
Once the blade passed through the shield and turned tangible again, Lydia's body abruptly vanished from where she was and immediately rematerialized at the place where the blade had gotten to.
