The coin hit the ground and the sound it produced was so loud that it echoed through out the auditorium, because no one was saying anything even they stopped breathing for the moment the coin was about to hit the ground.
Just as the coin hit, Zen and Ben both pushed their feet on the ground creating in impact to accelerate toward each other.
They both closing in to each other and the moment they reached close enough to strike, they both swung their fists toward each other and made contact with something but it wasn't their fist that struck with each other.
That was someone's hand holding their fists, it was Director.
He had come just in time to stop their brawl, he was grabbing both of their fists tight as the pressure of their punch was too intense for even him to bare.
The moment they struck their fist with directors bare hands, too intense aura was emitted and many students inside the auditorium fell on the ground.
