After hearing Golden Lion's description, Werther suspected he knew the secret behind Red-Haired's powerful Armament Haki.
"Was Roger the same as Red-Haired? Was his Armament Haki exceptionally strong?"
Golden Lion nodded.
"Yes. Stronger than Red-Haired is now, and far beyond the ordinary. If Roger concentrated all his Haki on defending one spot, I couldn't cut through it."
If Roger had been the same, then Red-Haired's Armament Haki wasn't the result of some innate gift. It was a technique.
"The principle is simple: reinforce Armament Haki with Conqueror's Haki. But simple as it sounds, I've only ever seen two people do it."
Werther understood at last. Red-Haired had been reinforcing his Armament Haki with Conqueror's Haki.
"Fusing two types of Haki? How is that possible?"
Although Conqueror's Haki and Armament Haki were both forms of Haki, Conqueror's Haki was mental energy, while Armament Haki was physical energy.
The two had nothing in common. There was no way to fuse them.
"Not fuse. Reinforce. It took me years of fighting Roger to notice the difference. As for fusing the two, that really is impossible."
"I see. I think I understand. Thanks."
Golden Lion's words opened a new door for Werther.
He had found the secret behind Red-Haired's powerful Armament Haki. If Red-Haired could do it, so could he.
Reinforcing Armament Haki with Armament Haki would be difficult for Werther to achieve.
The prerequisite was probably an overwhelmingly powerful Conqueror's Haki.
He couldn't reinforce it with Conqueror's Haki, but he could choose another kind of energy—lightning, for instance.
After Werther strengthened his Armament Haki to level twenty, a line of text had appeared beneath it: "Compatibility Awakening."
Werther had studied it for a long time. He had tried fusing all kinds of energy with Armament Haki, but nothing except lightning had worked.
Even
