Laura and Noah had been training their groups in their own way since the day they fought against each other.
After the fight, Noah's group had high morale while the morale of Laura's group significantly lessened.
Azaroth's speech had motivated them. They were filled with a desire to prove their superiority to him.
They wanted to tell him that they really possessed the determination he was looking for.
Meanwhile, the thoughts of Noah's men were relatively simple. They simply didn't want to experience a beating from Noah's hands. Thus, they tried their best to win.
As they fought, they felt as though Laura's men were attacking them in slow motion.
This sort of feeling was quite natural. During this time, these warriors had fought against Noah for so long that they were slowly getting used to his speed.
