"You... actually managed to damage my Crusher?!"
Zephyr's voice was low and hoarse, every word seemingly forced through clenched teeth, carrying the terrifying fury of a volcano about to erupt.
He was not angry because his indestructible weapon had been damaged.
He was angry because his dignity as a "teacher," as a "senior," had been challenged by a wet-behind-the-ears brat!
"Damage it?"
Yas wiped the blood from the corner of his mouth and grinned, his smile wild and arrogant.
"Old man, this is only the beginning."
"Next, I'll smash you and that scrap metal of yours to pieces!"
"You don't know your place!"
Zephyr was finally enraged beyond restraint, letting out a roar like a wounded lion.
"Since you're so eager to die, I'll show you the true gulf between us!"
"Brat, do you think Armament Haki is just a simple coating on your body to make it harder?"
As Zephyr spoke, he clenched his fists again.
This time, rather than growing denser, the ink-black Armament Haki on his fists began to tremble slightly at a peculiar frequency.
Hum.
An invisible yet incredibly sharp pulse spread outward from his fists.
"A true powerhouse can make his Haki seep into an enemy's body like flowing water, destroying it directly from its most vulnerable points!"
"This is the advanced application of Armament Haki-Internal Destruction!"
The instant his words fell, Zephyr vanished again.
This time, he was faster and more elusive than before!
Even Yas's Mantra Haki, which could capture light and shadow, could barely pick up a string of blurred afterimages!
Not good!
Alarm surged through Yas's heart. Without thinking, he moved to concentrate all the Black Lightning energy in his body in front of him, forming his strongest defense.
But Zephyr's attack had already arrived!
Thud!
An exceedingly dull sound rang
