"I'm a little weak now. This thing burns through far too much Haki, but the benefits are considerable too!"
When Roger forged his Black Blade just now, all the signs had shown on the outside.
As for the internal changes, Shane did not know what had happened.
In fact.
The blade turning entirely black was only an intermediate part of the process.
Roger had just carried out a comprehensive forging, the equivalent of a complete transformation. There had probably been many unusual changes in his body too.
From what Shane roughly understood, the Black Blade would first undergo a complete qualitative transformation, going a step beyond a Cursed Sword like Enma that ravenously sucked up Haki.
Then it would undergo a thorough reforging!
This required all of a swordsman's Haki. The slightest mistake could leave them dead at an enemy's hands.
The strange thing was.
Afterward, Roger's Armament Haki had actually increased sharply!
How was that possible?
Normally, once Haki was depleted, it took a long time to recover completely!
No!
The moment their fists clashed, Shane realized that Roger's Haki had not recovered rapidly. It had undergone a qualitative transformation!
There was clearly much less of it, with only a little coating the blade, yet its power was nearly the same as before!
If Roger fought at full strength, he would probably be even stronger!
Just as I thought!
The Black Blade was exceptionally strong, and with the qualitatively transformed Haki added to it, it was naturally even stronger!
Shane's fists were still only at the Cursed Sword stage of Enma, and his Haki had not undergone this qualitative transformation. That was why Roger felt so strong to him.
"Tempering a Black Blade is the key to a qualitative transformation in Armament Haki!"
