"I- I can't!"
The instructors' eardrums were damaged and they fell down to the ground. But not all of them were affected by it. One instructor at the master level and a warrior from the fifth floor of the library withstood the attack.
"Fool! You dare play tricks on us?"
"Hmph, so you aren't like those weaklings?"
The middle-aged man, however, jumped out and snapped the instructor's neck with ease.
"But you will die either way."
With the instructor dying, a warrior who guarded the fifth floor quickly pulled up force qi of sword and thrust at the enemy's neck.
"Huh? H-how did you!"
But the man grabbed force qi of sword by using force qi over his two fingers and grabbed it. This proved that the enemy was a very powerful warrior.
