"Waaah!"
With a cry of pain, Sirius was sent flying, crashing heavily onto the ground.
In front of him, King slowly withdrew his fist. An invisible current of force coiled around it, making the air around his fist appear slightly distorted.
"Did you feel it, Sirius? The Armament Haki wrapped around my hand."
"All I felt was pain!"
Sirius sat up while clutching his head. Teacher King had already smashed a huge bump into his forehead, leaving his dizzy mind somewhat muddled.
"That's alright."
Teacher King's calm voice now carried unmistakable delight as he slowly approached Sirius. "Try a few more times, and you'll feel it."
You bastard, your sadistic streak is acting up again, isn't it?
Sirius was utterly speechless.
He rubbed his head and stood up. "Teacher King, is there a gentler way to learn this?"
The original story had never explained in detail how Haki was trained.
Sirius only knew that Haki was a latent power possessed by everyone in this world. For ordinary people, though, it was buried too deeply within their bodies to ever be unleashed.
Only certain exceptional people could awaken Haki naturally, but that seemed to apply only to Observation Haki or Conqueror's Haki. Sirius had never heard of anyone naturally awakening Armament Haki. Perhaps Armament Haki could not be awakened naturally?
But Sirius believed that Two-Color Haki should have a systematic method of training.
Otherwise, how could Amazon Lily have made Haki so widespread?
The Navy's Six Powers were probably techniques like that.
Sirius remembered that in the original story, Jinbe had once said while fighting Who's-Who that within the CP system, they called Armament Haki Iron Body.
That Iron Body where anyone who used it died.
Humanity had developed because the experience of countless generations of predecessors accumulated over time.
