As the two guards were effectively eliminated, Mirelle heaved a sigh of relief.
"Why did we need to kill them after slicing their vocal cords?" Mirelle asked.
"We could have just put on a sound formation to prevent enemies from being alerted."
It was only when the crisis was resolved that her mind finally started to think properly.
There was no need for them to do such an act to infiltrate without alerting the enemy. One sound formation was enough for them to kill the guards on the spot, discreetly.
"Do you think everyone is a powerful Mage like you?" In response to her question, Claudia looked at her with a cold gaze.
"People who cannot use mana have to resort to such methods. Moreover, what happens if one day your mana runs out and you cannot maintain the sound formation? What can you do by then?"
Silent, Mirelle was pondering the question.
