One Piece: Enhanced Supreme Grade Sword

That's already an improvement of so much.

How much improvement will a +12 boost provide?

My heart was filled with overwhelming joy.

Kizaru immediately smiled and looked at Hill, instructing him, "Hill, hurry up and make the enhancement stone."

"At that time, I will definitely try to win credit for you in front of the Warring States Marshal."

“No problem, I’ll start production as soon as the funds arrive,” Hill replied with a smile.

After all, it's about making more enhancement stones.

The benefits to oneself are self-evident.

Kizaru returned the double-edged battle axe to Sentomaru.

Hold the double-edged battle axe in your hand.

Sentomaru examined the battle axe in his hands with obvious delight, turning it over and over. "This axe..."

"That's worth fifty million!"

"How many years would it take me to save up 5000 million Berries...?"

It was incredibly novel.

It was as if he were holding a priceless treasure.

Sentomaru's eyes gleamed; his axe was currently only enhanced to +5.

It can already amplify Armament Haki by more than ten percent.

Moreover, the sharpness of the tomahawk has increased significantly!

He thought to himself, "It seems I'll have to be more frugal from now on. Saving some money will allow me to upgrade my battle axe to a higher level."

"And we also need to kill more pirates to earn more bonuses."

He felt a secret sense of joy.

"With this axe, dealing with pirates will be much easier and simpler."

After five upgrades, the sharp double-edged battle axe not only became even sharper, but more importantly, it could amplify "Armament Haki".

An increase of more than ten percent is definitely not a small number.

Sentomaru gripped the massive double-edged battle axe tightly with both hands, the cold light flashing on the blades.

It exudes an extraordinary aura.

Wow!

Wow!

The axe blade sliced ​​through the air, producing a tearing sound, and a strong wind howled.

Sentomaru's face was full of surprise, a bright and happy smile covering his entire face, and he wielded the double-edged battle axe in his hand with great skill.

Each move was significantly more powerful than before.

"I'm much more comfortable wielding this axe than before. I need to go back and improve my Armament Haki. Then this axe will be an even greater boost to my combat power." Sentomaru's voice was filled with uncontrollable joy.

Admiral Kizaru, standing to the side, stroked his bearded chin and said with a smile in his eyes, "The function of this enhancement stone is indeed unexpected and quite terrifying."

After saying that, a slight hint of regret appeared on his face, and he continued, "Unfortunately, all the enhancement stones we have are used up, otherwise I really would like to give it a try..."

"Can this enhancement stone enhance my Ame-no-Murakumo sword?"

In terms of developing Devil Fruit abilities, Admiral Kizaru is undoubtedly one of the most outstanding strongmen on the high seas.

However...

Admiral Kizaru is also extremely skilled in swordsmanship!

While the swordsmanship of the three admirals may not be considered the pinnacle, it is certainly comparable to that of a master swordsman, and in terms of power, even some great swordsmen cannot match it.

Kizaru understood that if the enhancement stone in front of him could truly be applied to his "Ama-no-Murakumo-no-Tsurugi," it would allow his strength to be boosted to an even more terrifying level under the influence of the external object.

Hearing Kizaru's words, Hill also said with a hint of expectation, "I'm not even sure if the enhancement stone can enhance the Ama-no-Murakumo-no-Tsurugi, but we can try it once the enhancement stone is made."

Kusanagi no Tsurugi (Sword of the Clouds).

Hill knew that it was a sword that Kizaru had created using his Glint-Glint Fruit and the energy of photons.

It is extremely powerful.

He also remembered seeing it in the anime, where Marine Admiral Kizaru used his Ama no Kusanagi sword to directly confront Rayleigh and hold his own.

"Then we'll wait and see," Kizaru said with a smile.

With his hands in his pockets, he continued, "Then I won't disturb your research on the enhancement stones. Once the next batch is finished, have Sentomaru report to me. I'll let Marshal Sengoku have a good look at this amazing thing."

"Don't let anyone else know about the existence of the enhancement stone for now."

After receiving Hill's response, Kizaru leisurely walked out of Hill's laboratory.

"Oh no..."

"The tea's gone cold!"

·······

With the help of Sentomaru, the funds for the enhancement stones were quickly used to purchase materials for making the stones and sent to Hill's laboratory.

In the laboratory.

Hill was sweating profusely, his eyes shining brightly.

One by one, the strengthening stones were created in his hands.

[Congratulations, host, on successfully crafting the enhancement stone! You have earned 10 points!]

[Congratulations, host, on your success...]

·····

One enhancement stone after another was crafted by Hill, while the cold, detached voice of system notifications echoed continuously deep within his mind.

The voice was cold and lifeless.

But it seems to be injecting bowls of powerful chicken blood into Hill's body.

Hill finally fell into a deep sleep on the lab table when his eyes felt so heavy, as if weighed down by a thousand-pound boulder.

Sunset and sunrise.

Sunlight streamed into Marineford, which resembled a steel fortress.

Sentomaru got up early, carrying his huge double-bladed battle axe on his back, and walked out of his room with his head held high.

His pace was much faster than usual, and even the distance between his steps was longer.

"I wonder how many enhancement stones Hill has produced. Let's go check on them today."

Sentomaru made up his mind and also brought a delicious breakfast from the Navy mess hall.

A slight smile played on his lips as he whistled an unknown tune, the melody filled with a joyful mood.

"what..."

"Senmoumaru, Borsalino is too lazy to even ask you to bring him breakfast now?"

A clear, bright sound, as melodious as a wind chime, rang out.

Sentomaru stopped in his tracks and immediately greeted the newcomer with a smile: "Vice Admiral Gion, good morning."

"This breakfast isn't for the old man."

Chapter 5 Momousagi's Visit

"If it's not General Borsalino, then who is this breakfast for?" Momousagi smiled slightly, revealing a black mole at the corner of her mouth.

It has an indescribable charm and allure.

Bathed in the soft golden sunlight, it was even more radiant and captivating.

Sentomaru answered Momousagi's question in a muffled voice, "This was a gift from a friend of mine. If it weren't for him, how could I possibly have such a great weapon!"

He had barely finished speaking.

Gion's bright, jewel-like eyes lit up as she immediately noticed the enormous battle axe on Sentomaru's back.

A look of surprise flashed in his eyes.

He said with a hint of surprise, "Your axe seems to be much sharper than before, almost as sharp as my Kinpira."

Gion was filled with surprise.

She knew that her weapon was "Konpira," one of the twenty-one great swords.

On the vast and boundless sea, there are only twenty-one blades, each worth tens of millions of Berries, and incomparably sharp.

It is the work of a skilled blacksmith who poured his heart and soul into it.

It is an existence that cannot be replicated.

just now.

The double-edged battle axe of Sentomaru in front of him seemed to be almost comparable to his beloved sword, Kinpira, in terms of sharpness and hardness.

To Gion's surprise.

Gion exclaimed in surprise, "Could it be that a highly skilled blacksmith has recently emerged in the navy?"

"They actually managed to create such a weapon!"

Sentomaru pouted: "This is not something a blacksmith can make. The old man said we can't tell anyone that this is the result of Hill's enhancement stone."

"I'm the most discreet person in the world, I'm not going to tell you that my weapon can also amplify Armament Haki!"

Sentomaru seemed completely unaware that he had inadvertently mentioned Hill and the Enhancement Stone.

He looked righteous and indignant.

Gion's lips curled into a somewhat enigmatic smile, radiating charm: "Sheele... Enhancement Stone... Armament Haki amplification?"
