Failure is the mother of success

This was a duel, a duel that determined who could go further in the mass selection. It proved who was stronger. It was even an important duel that determined the honor of an organization!

This duel was supposed to be abnormally fiery, with both sides pushing hard at it, fighting a desperate battle, constantly exceeding their limits and surpassing each other. A battle of the century in which no one would be willing to lag behind. Finally it would end with a narrow margin that would be regretful.

But, why did this scene imperceptibly change?

Why did the duel transform into the present state?

Why?

Heartless sighed as his eyes gradually turned icy-cold.

"Tu Dahei, I will no longer hesitate or show any mercy. This is a duel. Sword is our only form of exchange. Using your full strength is the best form of respect."
