One Piece: Enhanced Supreme Grade Sword

Ok? !

Zefa was stunned for a moment, and then he realized something. Could it be that I had really misjudged him?

He then immediately switched the Kusanagi Sword from his right mechanical arm to his left hand, as his right arm had been broken due to a battle many years ago.

Finally, a robotic arm containing sea stone was installed.

Zephyr gripped the Kusanagi sword in his left hand. Known as "Black Arm," Zephyr unleashed Armament Haki, instantly hardening his elbow and hand with it.

All in one go.

The jet-black Armament Haki seeped into the Ame-no-Murakumo sword at a speed visible to the naked eye, instantly turning it from golden yellow to jet black.

A layer of black flames enveloped the sword.

It was surging and fierce.

It was filled with an explosive atmosphere.

In an instant.

The students present couldn't help but gasp in surprise.

"Such powerful Armament Haki!?"

"This is the first time I've ever seen this level of Armament Haki. Did Teacher Zephyr deliberately hold back a lot of his skills when he was teaching us?!"

"Zeff-sensei truly lives up to his title of 'Black Arm,' I really envy his Armament Haki!!"

"........"

At this moment, the trainees all stopped training without prior arrangement.

"Ain, did you see something?!" Binz asked a beautiful girl with long, wavy blue hair beside him.

The woman was dressed in a naval uniform, with an extremely exaggerated figure that made the uniform bulge out high. She had a pair of bright and captivating eyes like rubies.

"This sword seems unusual. Admiral Borsalino mentioned before that this sword is his Ame-no-Murakumo-no-Tsurugi. The Ame-no-Murakumo-no-Tsurugi has undergone such changes... It may have been custom-made for him by a master blacksmith, or it may be due to some special Devil Fruit ability."

Ain's eyes were fixed on the "Ama-no-Murakumo-no-Tsurugi" in Kizaru's hand.

Zephyr's heart jolted, his pupils dilated, and he stared in shock at Borsalino before him. "This sword...this sword..."

"It can make Armament Haki even stronger!!"

The fluctuation in his voice was entirely due to the intense turmoil within Zefa's heart.

Kizaru pouted and grinned, "Now you know why I said I wouldn't trade this Ame-no-Murakumo-no-Tsurugi even if it meant exchanging it for a Supreme Grade Sword, right?"

"It's a good thing that you've mastered such a powerful sword. Now you'll be able to focus more on swordsmanship." Zephyr didn't forget to give advice in his three sentences.

Such a sword is indeed unparalleled in the world.

No wonder Kizaru treasures it so much.

"This isn't luck, it's the power of technology!" Kizaru said with a smile. Zephyr rarely praised his students; he mostly urged them to train.

They even bluntly pointed out the mistakes and shortcomings in the students' practice.

Even now, as a Marine Admiral, Kizaru is no longer a cadet.

It was rare for Zeff to praise him, and Kizaru's mood instantly improved.

"The power of technology?!" Zephyr was stunned once again. "You're saying this weapon, which surpasses even the Greatswords of Musou, is a product of technology?!"

"How is this possible? The blacksmith's craft has been passed down for thousands of years. Iron smelting, quenching, forging... Could these processes be surpassed by machinery to create a weapon even more powerful than the Supreme Greatsword?!"

How can this be? !

He had seen standard-produced weapons before, but compared to the "Kusanagi-no-Tsurugi" before him, they were nothing but a pile of scrap metal.

This "Kusanagi Sword" can easily cut through those weapons.

There is no exaggeration whatsoever; the sharpness of the Kusanagi Sword is truly remarkable.

The students standing nearby were also greatly shocked and looked at each other in disbelief.

They could both see the shock and disbelief in each other's eyes and expressions.

Binz quickly turned to Ian beside him and asked, "Aren't you a scientist too? Is what General Borsalino said true or false?!"

Ain frowned, his pupils trembling slightly, filled with intense bewilderment: "As for technology, I can't say for sure, but regarding the possibility of creating such a weapon using technological power, I can only say..."

"It's incredibly difficult. Technology is always full of surprises, but I haven't received any information at all. We still don't know what's going on."

A strong sense of curiosity arose in her heart: how did she come to possess such a weapon?

Standing before Zephyr, Kizaru chuckled, "This is a secret of the Navy. Zephyr-sensei, let's go inside and talk about it."

This was a decision unanimously agreed upon by the Navy's top brass, and it cannot be revealed to others for the time being.

As for Zephyr's identity and status, Kizaru felt no burden at all when he was told this.

The two of them walked into the room together.

Kizaru said, "The creation of this weapon is entirely due to a new invention, the enhancement stone. The enhancement stone is very magical and can bring about a qualitative change in the weapon."

"And it can give you incredible abilities, and enhancing Armament Haki is one of the functions of the enhancement stone."

"My Kusanagi Sword has been strengthened many times and has become what it is now."

"・・・"

After hearing Kizaru's explanation, Zephyr's face showed excitement and agitation, and his slightly aged face looked much rosier.

"Now that you mention it, the navy is about to enter a new era."

He burst into laughter, expressing his true feelings: "Hahaha... With this, those pirates are in for a rough time."

Chapter 26 The True Naval Hero, Vital

From his own disciple, Kizaru.

Zefa has learned about the amazing effects of the "Enhancement Stone," which can enhance not only swords but also gauntlets and cannons.

Moreover, the power and range of the cannons have been greatly improved.

Zephyr was overjoyed and couldn't contain himself. He chose to stay in the Navy to train outstanding naval personnel, with the aim of making the Navy stronger.

It can eliminate more pirates and protect more civilians.

It's no exaggeration to say that...

His youth was all about the "navy"!

His middle age was all about the "navy"!

His old age was spent in the navy!

His life can be summed up in two words: "Justice"!

The legendary hero in the Navy is not the so-called "Iron Fist" Garp, but Zeff.

Only he deserves the title of legendary hero.

"Great!" Zephyr exclaimed with a smile. "It has been my lifelong wish for the Navy to flourish. I hope Hill can invent more inventions that will benefit the Navy."

"A strong navy brings benefits to the people."

Kizaru pursed his lips. "Zeff-sensei, let's get down to business. How can one reach the level of a great swordsman in swordsmanship?"

He has been at the level of a swordsman for many years, largely because he has devoted his mind and energy to developing his Devil Fruit abilities and Haki.

Another reason is that it is not easy for a swordsman to transcend to the level of a great swordsman.

A person's energy and time are limited.

It's impossible to be perfect in every aspect, nor can everything be satisfactory.

For strength.

Kizaru naturally knows how to make choices; the philosophy taught by Zephyr is not suitable for him.

"The realm of a great swordsman..."

Zefa said, "The most common people on this sea are swordsmen. Anyone who has a sword can be called a swordsman, and those who reach the level of cutting through iron can be called sword masters."

"Those who can reach this level have comprehended the breath of all things."

"And above the Sword Master is the Great Sword Master, who must forge their own path of the sword..."

"This is a transformation in spirit and will."

"It can also be described as a rebirth and baptism from body to soul."

"It's hard to say..."

"That's all I can tell you. After all, I'm not a true great swordsman either. You can ask Gion; she's been a great swordsman for quite some time now."

Kizaru nodded. "Let's go back and think about it first. If we still can't figure it out, we can ask Gion."

He turned and left the room.

Watching Kizaru leave, Zephyr thought of Momousagi, whom he had just mentioned, and a hint of admiration appeared in his eyes.

He muttered to himself, "I wonder what level Momousagi's swordsmanship has reached now, and how far he is from the legendary supreme swordsman."

"For a mere woman to achieve such a level, surpassing countless of my disciples, is truly admirable."

Legends can never be replicated.

In terms of swordsmanship alone, the Navy's reserve admiral is undoubtedly the strongest swordsman.

·······

"Hill, have you thought of any new moves lately?!" Momousagi couldn't help but ask curiously, as the Hundred Steps Flying Sword move had broadened her horizons.

I've made quite a bit of progress in my swordsmanship recently.

Hill smiled helplessly, "That move was just a stroke of inspiration; I haven't thought of any other sword moves lately."

He held the rosary beads and chopped forward.

He easily cleaved a stone several meters in size in two with a single stroke, leaving a smooth and flat cut surface, like polished and waxed jade.

Momousagi commented, "That was a good sword strike. I didn't expect your swordsmanship to have reached this level in such a short time. It took me almost a year to learn it myself."
