One Piece: Enhanced Supreme Grade Sword

Everyone else was also full of anticipation.

With the remaining enhancement stones in hand, Hill followed a group of high-ranking naval officers to the artillery training ground.

Here, Hill saw rows of cannons of various sizes, each one resembling a ferocious beast crouching on the ground, ready to hunt.

The pitch-black cannon barrel exuded a ferocious aura.

At this time, the navy had already cleared out the artillery range, after all, the existence of the "enhancing stone" was a secret weapon that could not be made public.

When the enhancement stone is exposed, it will surely be the moment when the navy bares its fangs and displays its power.

"Let me try it myself this time!" Sengoku picked up the enhancement stone and walked to the cannon, his heart filled with anticipation.

Whether enhancement stones can enhance cannons is a different matter than weapons. Cannons are weapons of mass destruction, and can be used without mastering Haki.

It is universally applicable and can be used even by ordinary navies.

Weapons enhanced with enhancement stones can only unleash their full power when wielded by a Marine who is proficient in Haki.

Therefore, the two represent completely different meanings.

Although Vice Admiral Tsuru calmly observed Sengoku, there was still a hint of tension in his eyes. "I hope we can succeed."

The other naval commanders also focused all their attention on Sengoku, including Hill.

Sengoku held the strengthening stone and slammed it towards the cannon. The strengthening stone began to merge with the cannon, and in the blink of an eye, a corner of the strengthening stone was completely integrated into the cannon.

Zhan Guo's eyes lit up—he had succeeded!

The strengthening stones really could enhance the cannons, and he suppressed his excitement. It was too early to call it a success; the most important thing was...

The most important thing is to understand what changes will occur after the artillery is strengthened.

The intensification process in the arena also captivated the attention of everyone present.

Kizaru's face showed admiration. "This is truly unexpected. I never thought that enhancement stones could actually enhance cannons. This invention is something that could change the world!"

"Fortunately, this thing appeared in our navy. If it had fallen into the hands of pirates, it would probably have disrupted the peace of the sea and caused a tsunami that would sweep the world." Vice Admiral Tsuru's face showed a hint of relief.

If enhancement stones were to fall into the hands of pirates, the consequences would be unimaginable.

The strengthening stone quickly and completely disappeared.

Sengoku stared intently at the cannon before him. From the outside, there was no visible change, but it was indeed stronger than before in terms of durability.

Lieutenant General Tsuru said, "Then let's try firing."

Sengoku nodded, took out the prepared lighter, and lit the cannon's fuse. The sparks immediately ignited and quickly disappeared into the cannon along the fuse.

Bang!

The cannon fired instantly!

It rapidly ascended into the air, then fell at breakneck speed into the distance, causing a violent explosion.

With a loud crash, rubble flew everywhere, and dust billowed up.

Sengoku and Vice Admiral Tsuru exchanged a glance, both seeing surprise in each other's eyes!

Chapter 15 The Daring Blackbeard

Lieutenant General Tsuru laughed and said, "The power of the artillery has been improved, and the range has also been significantly increased, by nearly twenty meters!"

Sengoku nodded in agreement with Lieutenant General Tsuru's analysis and judgment, his eyes filled with surprise. "It seems that strengthening cannons with enhancement stones is feasible, and this is only the effect of one enhancement."

A range of twenty meters.

It is enough to increase the enemy's strike range by 20 meters, giving the navy a greater advantage in naval operations and making the navy safer. The benefits are obvious.

This made Sengoku, the naval admiral, extremely excited. If it were equipped on naval warships and in naval bases, the navy would be even more invincible.

Give the pirates a good beating!

"Good!!" Akainu shouted excitedly.

Navy warships are already more advanced in technology and have better artillery than ordinary pirate crews. Now, with the addition of the enhancement stones, the Navy's advantage will be further amplified.

Vice Admiral Tsuru looked at Hill and said, "You are truly a lucky star for the Navy. Hill, you will definitely be an extremely important person in the Navy in the future!"

It now seems that the invention of the enhancement stone alone is enough to rival the genius scientist Vegapunk of the Navy. Previously, the enhancement stone was not universal, but now, after testing the enhancement cannon, everything is different.

It has been proven that the enhancement stone is universal, capable of enhancing cannons that even ordinary naval personnel can operate.

Hill was overjoyed, as this meant that the Navy's demand for enhancement stones had increased by at least several times, or even ten times.

He could already see massive amounts of points rolling in, and he was enjoying himself in the world of treasure chests.

A bright future and immense power beckon him!

Sengoku couldn't resist continuing to enhance the cannons with enhancement stones, each stone bringing a change, making the cannonballs even more destructive, and their range far exceeding everyone's expectations.

Until the success of enhancement to +12.

The power of a single shell is about five times greater than before the upgrade!

The range has been doubled!

These are all extremely alarming numbers, capable of playing a decisive role in determining the outcome of a war.

Sengoku grinned from ear to ear, “The Navy will surely usher in a bright future. This is an invention that will change the times. Will, I will personally report your matter to the Five Elders. Your merits and rewards will be announced soon.”

A total of 60 enhancement stones were used, leaving 20 enhancement stones. Sengoku also planned to report this matter to the Five Elders of the World Government and strive for the World Government's greatest support.

Mass production of reinforced stone.

The other naval officers nodded in agreement. Akainu said, "I hope the World Government can allocate more funds. Such a magical and powerful thing as the Enhancement Stone should be produced in large quantities so that we can equip every warship with the enhanced cannons and launch a devastating attack on pirates!"

at this time.

A figure rushed over, interrupting the group. Marine Rear Admiral Branno spoke up: "Fleet Admiral Sengoku, Blackbeard Marshall D. Teach, has contacted the Navy, specifically requesting your response. They want to make a deal with the Navy..."

He hadn't finished speaking.

Marine Admiral Akainu's face darkened, his voice blazing with anger, "Pirates?! They want to make a deal with the Marines?!"

"The Navy will not agree to this, and such audacious pirates should be completely wiped out!!"

Hearing the name Brannus mentioned, Hill's heart tightened. "Blackbeard, he wants to make a deal with the Navy? It seems that's all that can be it. Portgas D. Ace has already been captured by that guy..."

Hill felt a strong sense of urgency; it seemed that the date of the Marineford War was not far off, less than six months at most.

The highly anticipated Marineford War is about to begin.

Although scientists in the naval science force would certainly be under the strict protection of the navy and would not participate in this unprecedented war.

However, Hill still wanted to witness the war between the Whitebeard Pirates, one of the Four Emperors, and the Navy, rather than learning about it through news or Den Den Mushi.

The Seven Warlords of the Sea, the Navy, the Whitebeard Pirates, the Blackbeard Pirates, Luffy, the Revolutionary Army, the Red-Haired Pirates, and many more will all make their dazzling appearances.

Hill didn't want to miss such a big battle.

However, without strength, it is absolutely impossible to join such a dangerous battlefield.

As Brannu and Akainu spoke, the atmosphere on the field became heavy. Vice Admiral Tsuru frowned. "Blackbeard Marshall D. Teach seems to have defected from the Whitebeard Pirates' ship. As for other information, we don't know. Blackbeard doesn't have any bounties at the moment, but the other pirates with him do."

"However, the bounties are all extremely low."

Anyone who can betray the Whitebeard Pirates, one of the Four Emperors, and still be alive is definitely not simple; you can tell just by the fact that they dared to make deals with the Navy.

Brannu then added, "The bargaining chip they're using in their deal with the Navy is Portgas D. Ace, the second division commander of Whitebeard's army!"

If it weren't for this name, he wouldn't have been in such a hurry to report this news to Sengoku, the identity of Fire Fist Ace...

"Fire Fist Ace?!" Sengoku's expression turned serious after a moment of surprise.

Akainu remained steadfast in his stance, "Even if it were Portgas D. Ace, the Navy would never make a deal with pirates!"

"Oh...that's terrifying. Blackbeard, that not-so-famous pirate, actually defeated that guy Fire Fist Ace. This really worries me." Kizaru said with a fearful expression and a pout.

Fire Fist Ace was a Logia-type Devil Fruit user with the Flame-Flame Fruit ability. He was once famous throughout the seas, and the World Government even extended an invitation to him to become one of the Seven Warlords of the Sea.

That guy eventually joined the Whitebeard Pirates and became the second division commander, and he was very strong.

Kizaru instantly memorized the name Blackbeard Marshall D. Teach, and a strong sense of vigilance rose in his heart.

At this moment, Vice Admiral Garp suppressed his anger and pain, remaining silent with tears welling up in his lowered eyes.

With his head drooping and everyone's attention focused on the information Brannu had given, no one noticed anything unusual about Garp.

Sengoku asked Bran, "What does Blackbeard want to exchange for Fire Fist Ace and the Navy?!"

“Blackbeard specifically requested to discuss this matter with you personally. He said he would contact us again via Den Den Mushi in an hour,” Brannu said truthfully.

At this moment, Sengoku's mind raced. He understood Fire Fist Ace's identity. If the Navy accepted "Fire Fist Ace"...

This will ignite a war with the Whitebeard Pirates, one of the Four Emperors.

His gaze fell on the cannons. "Perhaps this is our chance, a chance to wipe out Whitebeard completely."

Chapter 16 Rare Reward: Gourmet Cells

Sengoku frowned, pondering the consequences of this matter, and asked Tsuru beside him, "Tsuru, what do you think? Now that we have the enhancement stones, the Navy's combat power will increase rapidly."

The appearance of the strengthening stone greatly boosted the confidence of the Warring States period.

This is an opportunity, a chance to wipe out the Whitebeard Pirates, one of the Four Emperors!

The Four Emperors' pirate crews have dominated the New World for many years. Ever since he became the Fleet Admiral of the Navy, he has always dreamed that one day his justice would reign supreme over the world.

However, the immense power of the Four Emperors forced the Navy to take them seriously, and the World Government even established the Seven Warlords system to keep the Four Emperors in check and maintain balance in the seas.

If a war were to break out between the Whitebeard Pirates, it would have far-reaching consequences.

This was an incredibly difficult decision.

This war was destined to have only one main theme: death!

It is also the price that must be paid for victory.

Lieutenant General Tsuru naturally knew what this decision meant. "This matter needs to be discussed carefully, and every aspect must be taken into account."

"Let's hold an emergency meeting right away to discuss this matter!" Sengoku said, then looked at Hill and said in an extremely solemn tone, "Hill, we'll have to ask you to handle the production of the enhancement stones. The Navy will do its utmost to provide both funding and materials."

"Your task now is to produce enhancement stones in the shortest possible time."
