One Piece: Enhanced Supreme Grade Sword

His sword is the first generation Kitetsu, one of the twelve Supreme Grade Swords, and is even known as the "Demon Sword"!

Sengoku immediately said, "The changes to the Kusanagi Sword are not limited to these. It can also greatly amplify Armament Haki, which is also thanks to the enhancement stone."

Once the Five Elders approve of the Enhancement Stones, it's a certainty that a large amount of funding will be allocated to manufacture them, which would be extremely beneficial for the Navy.

Sengoku also took the enhancement stones out of his pocket. Apart from the enhancement stones he had used last time, he brought all 20 remaining enhancement stones with him at once.

The purpose was to personally demonstrate the magical effects of the strengthening stone in front of the Five Elders later.

The Fifth Elder didn't hesitate and immediately infused the Kusanagi Sword with Armament Haki. The Haki, which was no weaker than that of a Marine Admiral, turned the entire Kusanagi Sword from golden yellow to black iron.

The blade reflected an astonishingly cold light.

The change in the intensity of Armament Haki shocked the Fifth Elder. His face was filled with disbelief, and he exclaimed somewhat incoherently, "Armament Haki has really become stronger, much stronger!!"

The amplification of Armament Haki by nearly half was so terrifying that it shocked the Fifth Elder.

"If I had this sword back then, I could have defeated Rocks all by myself!" the Fifth Elder said with some emotion.

The eldest elder, the leader of the Five Elders, looked surprised and couldn't help but ask, "Is it really that exaggerated?!"

Rocks' power was evident to all the Five Elders back in God Valley; none of them could defeat him in a one-on-one fight.

The Fifth Elder now says that if this sword had existed back then, he would have been able to defeat Rocks single-handedly, which shows how highly he regards this sword.

Even the Twelve Supreme Grade Swords, the Demon Sword Kitetsu, had never received such high praise from him.

"It's no exaggeration at all. This sword has amplified my Armament Haki by half, which is enough to increase the power of every slash I make by a large margin," the Fifth Elder replied excitedly.

He urged Sengoku, "Where are the enhancement stones? You say they can enhance weapons, so let's try them with my Onikiri!"

The Fifth Elder returned the Ama no Kusanagi sword to Kizaru, and immediately took out the Kitetsu sword himself, looking extremely impatient.

Sengoku reached out and took the Onikiri from the Fifth Elder, and at the same time picked up the enhancement stone and began to enhance the demon sword Onikiri, causing the Five Elders to watch nervously.

They witnessed a miraculous scene: the enhancement stone disappeared from the demon sword Onikiri.

Many powerful individuals with keen senses were surprised to discover that the demon sword Onikiri had indeed changed.

Sengoku did not stop what he was doing. The effect of strengthening once was there, but it was far less obvious and astonishing than the effect of strengthening 12 times.

So I decided to upgrade the demon sword Onikiri 12 times in one go.

One by one, the enhancement stones disappeared into the demon sword Onikiri.

Suddenly, a black ghost emerged from the demon sword Onikiri, like a terrifying vengeful spirit!

Its entire body is pitch black, yet it clearly has a human-like physique, and its empty eyes create a chilling visual impact.

"What is this?!" Sengoku exclaimed in surprise.

He couldn't help but throw the Onikiri in his hand to the ground, making a clanging sound.

Everyone was startled by the sudden change before their eyes, and they all tensed up, watching the fierce ghost in the sky with vigilance.

Kizaru's lewd face showed surprise. "Why did this thing appear after the Kitetsu was strengthened? There was no such change when my Ame-no-Murakumo-no-Tsurugi was strengthened."

Is it the strengthening stone that's causing this?

Or is it a problem with Onikiri itself?

"Don't be nervous!!" The Fifth Elder's expression was somewhat strange, a mixture of surprise and delight. "This thing came from Guiche; it must be the manifestation of Guiche's will!"

Long ago, he sensed a soul force within the first generation of Kitetsu, but this soul force could not communicate verbally and was extremely weak.

It was only after decades of companionship, coupled with the Fifth Elder's extraordinary perception, that he was able to detect the soul's will within the Ghostly Blade.

The black monster that has suddenly appeared is very likely the soul will that exists within the Onikiri.

The Fifth Elder immediately picked up the Ghost Blade from the ground, and the black, soul-like thing in the air circled around him several times.

Then it burrowed into the blade of the Onikiri, appearing on the edge of the blade. On its featureless black face, the corners of its mouth were open, as if it were smiling.

Sengoku breathed a sigh of relief and said, "I didn't expect that the enhancement stone would cause such an unknown change in Onikiri. We had no idea about it before either."

"It's alright, this is a good thing!" the Fifth Elder said excitedly. "I can feel that this sword has become stronger, and I can clearly sense Guiche's emotions!"

It's a very strange feeling, as if there's an extra child in the Kitetsu who can't speak but can express his emotions.

It makes communication easier.

As Onikiri became even more bizarre, he also became stronger!!

Complete the mission in Chapter 23 to unlock new items.

The Fifth Elder was overjoyed, his body trembling slightly with excitement. "Gui Che has been with me for decades, and now I feel like it has grown up."

I inexplicably felt a sense of kinship, like that of an old father.

Moreover, the current Kitetsu also possesses the same effect as Kizaru's Ame-no-Murakumo-no-Tsurugi in amplifying Armament Haki, which greatly excited him.

"I want to test the power of the Ghost Blade now. I believe it will bring me a huge surprise," the Fifth Elder said with a hearty laugh.

A glint of light flashed in his eyes behind his glasses.

The ghostly figure moved within the blade, conveying a joyful emotion to the Fifth Elder.

With anticipation on his face, the Grand Elder stepped forward and said, "Then let everyone witness the power of the enhanced Onikiri!"

As the Fifth Elder just said, if he had had a sword like that back then, he would have been able to defeat Rocks. The First Elder also wants to truly experience just how powerful a sword enhanced by the enhancement stone really is.

The group walked out of the conference room.

The entire Holy Land of Mary Geoise was paved with bricks and stones, and the group left Mary Geoise and came to the Red Earth continent outside the city.

as far as the eye can see.

A world of red, devoid of vegetation, with the soil beneath your feet entirely red.

Gripping the hilt of the Onikiri tightly, the Fifth Elder of the Five Elders appeared somewhat excited, Armament Haki rising from his arm, and black energy spreading across the blade.

Armament Haki surged rapidly at a visible speed, covering the entire blade of Kitetsu, while the ghostly figure within the blade also became somewhat violent, revealing its ferocity.

"One-Sword Style: Demon Night Slash!!"

With a slash of the sword, a burst of sword light shot out.

The slash, tens of meters high, instantly cleaved the ground, creating a deep, bottomless ravine.

The slash didn't disappear; instead, it continued forward!

It disappeared into the horizon.

All that remained was a crack several meters wide, stretching to the horizon.

The power of a single sword strike is terrifying.

According to everyone's Observation Haki, this sword strike traveled several kilometers!

The eldest of the Five Elders was so excited that he repeatedly tapped the ground with his cane, exclaiming, "Excellent! Excellent! The enhancement stone can actually increase strength by so much!!"

The results were remarkable, much to his delight.

With a large number of enhancement stones, a batch of "divine artifacts" could be created, and the combat power of the World Government and the Navy would be boosted to an absurd level.

At that time, more countries will choose to join the World Government, and the World Government will reach an unprecedented era of strength.

The Fifth Elder looked at the trench he had carved and laughed happily, "If I were a few decades younger, I might even have a chance to compete for the title of the world's greatest swordsman."

With the help of the Onikiri, the power of his slashes reached a level he could only dream of, even if the world's greatest swordsman, Hawkeye, were to appear before him now.

He was also confident that he could defeat it.

The enhanced Onikiri brought him a tremendous increase in strength!

Seeing the Five Elders in high spirits, Sengoku immediately asked, "The cost of making one of these enhancement stones is 1 million Berries. Elder, how many should we make?"

“Ten million per stone, no problem at all. I’ll have the finance department allocate 100 billion Berries to the navy to make enhancement stones later!” the elder replied readily.

"After the enhancement stones are made, send half of them to Mary Geoise. With these enhancement stones, we can create a group of elites."

at this time.

The navy personnel were also astonished by the figure mentioned by the Grand Elder. He had actually allocated 1000 billion Berries, which completely exceeded their previous expectations.

I thought 20-30 billion Berries would be pretty good, but the Grand Elder waved his hand and prepared to allocate 100 billion Berries to the Navy.

Sengoku was overjoyed. "Understood. Once the first batch is produced, we will immediately send some to Mary Geoise."

The Grand Elder nodded in satisfaction, while also instructing, "As for Hill, who invented the strengthening stone, he will be richly rewarded. His treatment and benefits will be raised by three levels, and he must be given special protection. Absolutely no accidents can be tolerated!"

"Of course, we will definitely protect such a genius well," Zhan Guo said with a smile, having exceeded expectations.

With enough enhancement stones, we will be able to deal with the Whitebeard Pirates more easily and reduce losses.

He also took the opportunity to bring up the second matter, "Elder, regarding the second matter of this visit, the Navy has captured Portgas D. Ace, and Portgas D. Ace's true identity is the son of the Pirate King Gol D. Roger."

These words were spoken.

The relaxed and joyful atmosphere from just moments ago vanished without a trace.

The air seemed to freeze instantly, as if compressed by the powerful aura of the Five Elders.

The atmosphere instantly became tense.

"The son of the Pirate King Roger... is actually Fire Fist Ace?!" the Second Elder murmured, truly astonished.

The blond Third Elder spoke in a somewhat heavy voice, "We originally thought Roger had no bloodline at all, but we never expected him to be right under our noses. We even recruited him to become one of the Seven Warlords of the Sea."

The elder's eyes flickered slightly as he looked at Sengoku and said solemnly, "It seems you are planning to use Fire Fist Ace to deal with Whitebeard, and at the same time, you are also planning to completely eliminate Roger's bloodline."

"On this matter, all five elders agree that Sengoku should go ahead and handle things regarding Fire Fist Ace!"

He thought that after destroying the Rocks Pirates, the world was in his hands. But unexpectedly, the fame of Shiki and Roger's Pirates rose one after another. Shiki even recruited countless pirates and became the Pirate Grand Admiral.

Roger ushered in the Great Pirate Era, and most of the New World was controlled by the Four Emperors.

The other five elders also nodded in agreement.

After receiving the approval of the Five Elders, Sengoku felt relieved and said confidently, "With the Enhancement Stones here, the Whitebeard Pirates will be able to take us on as long as they dare to come."

"We must wipe them all out at Naval Headquarters!"

With the existence of the enhancement stones, Sengoku was full of confidence. With the 1000 billion Berries allocated by the Five Elders, the enhancement stones would be enough to create a batch of highly threatening weapons.

the other side.
