One Piece: Enhanced Supreme Grade Sword

The gleaming blade immediately reflected bursts of light, illuminating the laboratory.

Hill was forced to squint slightly by the sudden bright light, and after his eyes adjusted, he praised, "What a fine sword! It truly deserves to be one of only twenty-one great swords on the sea."

He also harbored strong expectations.

Yesterday, I helped strengthen Sentomaru's double-edged battle axe to +5, which greatly improved the axe's hardness and sharpness.

However, Sentomaru's double-edged battle axe is essentially inferior to Vice Admiral Momousagi's Great Grade Sword, Kinpira.

Momousagi and Sentomaru, who were standing beside her, both cast their gazes at Sheele.

Momousagi said in a somewhat low voice, "This sword has been with me for over ten years... it's like family to me..."

Apart from this sword.

My closest relative in this world is Sister Crane.

"Although it's just a sword, it's also the most trustworthy partner," Hill said with some emotion.

He also understood that many swordsmen regarded their swords, which they kept by day and night, as their companions, or even their lives.

Hill held the enhancement stone in one hand and a long sword in the other.

Holding the enhancement stone close to the blade of the Golden Blade, the edge of the stone touched the snow-white blade and immediately emitted a faint light.

The shimmering light testifies to the extraordinary nature of the enhancement stone.

The strengthening stones began to gradually integrate into the blade of the Kinpira sword.

In the blink of an eye.

A complete enhancement stone was as if it had been split in two, leaving only one half.

Finally, it disappeared completely, and the light vanished, as if nothing had ever happened.

'Great Grade Sword Kinpira successfully upgraded; current upgrade level +1.'

Hill also picked up the second enhancement stone and began the second enhancement of Kinpira without stopping.

Momousagi and Sentomaru, who were watching the entire enhancement process from the side, did not disturb Sheele's actions.

Momousagi's eyes shone with a light that flickered with surprise: "How amazing..."

"I thought it was just reforging the Kinpira and adding the strengthening stone components, but I didn't expect that this magical strengthening stone could directly fuse with my Kinpira."

"Incredible!"

I've never seen such a magical scene before, and it even defies some of Momousagi's common sense.

"Isn't it amazing? I was quite shocked when I first saw the enhancement stone!" Sentomaru recalled the first time he enhanced his double-edged battle axe.

There was even a moment of suspicion that Hill had used some kind of Paramecia-type Devil Fruit.

It was only later that I realized this was Hill's "magical invention".

Absolutely breathtaking!

One enhancement stone after another.

In just a short while.

The five enhancement stones were then completely integrated into the body of the Kinpira sword.

Hill smiled slightly, handed the Kinpira sword to Momousagi, and said, "It's been successfully enhanced now. Try out the changes this sword has undergone."

Looking at the golden pendant in Hill's hand.

Momousagi stared intently at it, then eagerly took the Kinpira.

He stood with his sword drawn.

His gaze followed the blade slowly upwards, unblinking, and he exclaimed in amazement, "It really has become even sharper! I can clearly feel the change in Kinpira!"

Kim Pira, with whom he spent every day, had also been through countless battles.

They take meticulous care of "Konpira", and perform maintenance work with utmost care time and time again.

No matter how slight the change in Kinpira was, it did not escape Momousagi's keen eyes.

Filled with surprise, Momousagi's face broke into a charming smile. Her slender, fair fingers gently touched the blade, feeling the changes brought about by the magical strengthening stone.

"Its sharpness is amazing, it's incredible..." Momousagi exclaimed involuntarily.

Hill gave a mysterious smile: "This isn't the strongest effect of the enhancement stone. Try using Armament Haki on Kinpira's transformation!"

The most important function of enhancement stones is to amplify the weapon's Armament Haki.

Hearing Hill's prompt.

Momousagi, who was in shock, quickly came to her senses and immediately used Armament Haki.

Her jade-like arms instantly turned as black as ink, reflecting a metallic luster, and a purple flame rose from her hands.

It immediately spread from the hilt of the Kinpira sword to the tip.

The originally bright, silvery-white sword blade turned into black metal under the effect of Momousagi's Armament Haki.

Hill knew.

That's Armament Haki!

This was also the first time he had ever seen such powerful Armament Haki in person. Staring directly at Kinpira, it gave him a feeling of trepidation.

That was the power he admired!

Chapter 7: The First Enhanced Weapon of Level 12 is Born

A bewitching, dark purple flame swirled around the blade.

Armament Haki!

For Hill, it was a powerful and mysterious force that he longed for, and he was also aware of his own limitations.

Based solely on his current physical condition.

They are simply not qualified to practice Armament Haki.

A strong desire was hidden deep within his deep eyes.

Momousagi's expression changed, and she exclaimed in disbelief, "Really! It's true!"

"It really can amplify Armament Haki!"

As a candidate for admiral in the Navy, Gion, codenamed Momousagi, is undoubtedly one of the strongest individuals on this sea, possessing exceptional sensory abilities.

He clearly felt that the Armament Haki he transmitted to the Kinpira Blade had become even stronger!

This is definitely not an illusion.

The magnitude of this increase is exceptionally pronounced.

"It's unbelievable! The enhancement stone is simply amazing!" Momousagi exclaimed with delight. "The current Kinpira feels almost on par with the Supreme Grade Swords."

There are only 12 of the 21 Great Swords on the sea, and each one is a legendary weapon.

Now she feels that, under the effect of the enhancement stone, the once insurmountable gap between the Great Grade Swords and the Supreme Grade Swords is significantly decreasing.

Even Momousagi, with her meticulous and calm mind, couldn't help but feel a strong surge of emotions. She murmured absentmindedly, "Hiss... such a terrifying change after only five enhancements. If it were a Supreme Grade Sword, what kind of changes would occur?"

The eerie flames formed by Armament Haki on the blade seemed to flicker in response to the intense fluctuations in Momousagi's heart.

It's like adding fuel to the fire.

It rose several points higher again.

Momousagi quickly calmed down her inner turmoil, and under her control, the Armament Haki on the sword vanished without a trace.

He turned to Hill and said, "Could you help me strengthen Kinpira a few more times? Just don't damage it."

Such a noticeable change and enhancement was achieved using only five enhancement stones. If, as Hill said, it can be enhanced twelve times without any damage, then...

Then her Kimbira will definitely undergo a tremendous change.

It's not impossible for it to rival, or even surpass, the twelve Supreme Grade Swords.

Peach Rabbit suppressed her intense excitement and anticipation, her bright eyes filled with a burning desire and expectation.

“Of course, but it’s still 10 million Berries for one enhancement stone. Just remember to deliver it to the lab as soon as possible.” Hill nodded.

"it is good!"

Momousagi readily agreed: "Then I'll leave it to you! You don't need to worry about the money at all!"

They received a response from Momousagi.

Hill was relieved, as he was a member of the Navy.

He knew, of course, that with Momousagi's assets, hundreds of millions of Berries were no problem at all.

The navy can also receive a portion of the bounty when they capture wanted criminals.

"Hill, let's get started. I also want to see what kind of changes will occur after a weapon is enhanced 12 times." Sentomaru was also getting impatient.

I want to see what kind of changes will occur to the twenty-one large swords under the effect of the strengthening stone.

To what extent will the amplification of Armament Haki reach?

Hill was also filled with curiosity.

He immediately took the enhancement stone and began to further enhance Kinpira.

One by one, the strengthening stones were incorporated into the blade of Kinpira and disappeared, and the blade of Kinpira underwent a change that was visible to the naked eye.

Smooth as a mirror.

Hill's face was clearly visible.

"Enhancement successful, current enhancement level 12."

Become!

Hill's eyes held a hint of joy, and he did not continue to use enhancement stones on Kinpira.

It has already reached the enhancement level of 12. If it is enhanced further, it will have to bear the risk of weapon damage, and even the success rate of enhancing the weapon after enhancement level 12 will be affected.

Hill didn't know either.
