One Piece : Prince of Charlotte Family

This was a decision Wilhelm made after careful consideration.

Although the dual-sword style was powerful, it didn't suit his fighting style.

He only needed one supreme sword—one truly worthy of him, capable of bringing out his full strength.

"Combining so many legendary swords into one… that's insane."

Shiryu of the Rain's eyes burned with excitement. "I wonder what kind of ultimate blade this will create!"

As a swordsman, how could he not look forward to this?

"Alright, then I won't hold back!"

Dr. Hawkins didn't hesitate.

Activating the Munch-Munch Fruit, his massive mouth opened wide.

"Kaka… Kakudang…"

One by one, the legendary swords—Huche, Raikiri, Hualan—were bitten and shattered effortlessly, even with their scabbards still on.

He swallowed them whole.

Then came the Tenseiga, the Shichiseiken, and the First Generation Kitetsu…

He devoured them all in one gulp.

"Munch-Munch Factory: Fusion!"

Dr. Hawkins' stomach twisted violently.

Not long after…

His metallic stomach split open like a pair of doors—

And from within, a magnificent new sword emerged.

Its shape was similar to Tenseiga, but the blade was larger, more refined.

The cold steel gleamed, engraved with intricate patterns.

But unlike the original—

The blade's surface was inlaid with dazzling gemstones, embedded perfectly into the metal.

Each side had seven gems, arranged in the formation of the Big Dipper constellation, glowing brilliantly in different colors.

"This sword is forged from the finest materials of legendary blades, fused with Hawkins Alloy, while retaining their original properties. It is truly an unparalleled weapon."

Dr. Hawkins smirked.

"The gemstones have been infused with my alloy, making them as hard as diamonds, resistant to water, fire, extreme heat, and cold. They're embedded deep into the blade, seamlessly fused—it's impossible for them to fall off!"

He then pulled out an equally gorgeous scabbard from his stomach.

Together, the sword and scabbard looked like masterpieces of art—their shimmering glow mesmerizing to anyone who gazed upon them.

But beneath that beauty, a mysterious and eerie aura pulsed throughout the sword, making it impossible to ignore.

Anyone who stared too long felt their mind waver.

"This is like a work of art!"

The three Smoothie sisters couldn't help but be captivated.

"That overwhelming demonic aura… it's no weaker than the First Generation Kitetsu!"

Shiryu of the Rain's eyes were blazing with excitement.

From this outrageously magnificent sword, he could feel an ominous, chilling presence—the unmistakable aura of a cursed demon blade.

"Clang!"

The blade let out a clear, crisp resonance—deep and haunting.

Wilhelm gripped the new sword, his gaze sharp.

"Swoosh—"

An overwhelming, sinister force surged from the blade.

Green and red energy swirled around it, coiling like living entities.

The surrounding temperature plummeted instantly.

A deep chill spread through the air.

It sent shivers down everyone's spine.

"Even the demonic power of the Shichiseiken and the eerie aura of the First Generation Kitetsu fused perfectly?"

Wilhelm's eyes gleamed as he examined the exquisite, ultimate blade in his hands.

He chuckled.

"Interesting."

He ran his fingers along the flawless edge of the sword and spoke its name:

"Cong Yunya."
