One Piece: Enhanced Supreme Grade Sword

Akainu frowned slightly. "If the enhanced eyepatch can amplify Observation Haki, then you have to wear the eyepatch during battle. Is there anything else that can be used as a substitute?"

Then, he focused his gaze on Kizaru. This guy never takes off his sunglasses, and if the sunglasses were upgraded, they could also amplify his Observation Haki.

You might consider wearing a light-colored pair of sunglasses.

"Let's give it a try!" Zhan Guo decided. He was also eager to know the answer to this question, and at the same time, he had a faint expectation that different results would occur.

Eyes and eye patches have similarities, but also differences.

Lieutenant General Tsuru also cast a very concerned glance, his eyes filled with interest. "It seems we are far from fully utilizing the power of the strengthening stones. Everyone should pay more attention to the application of the strengthening stones."

Today's events have once again shattered her understanding.

The potential of the strengthening stones has not yet been fully explored, and this unexpected surprise served as a reminder to her.

Perhaps strengthening other things with enhancement stones will bring unexpected surprises.

Kizaru's lips curled up slightly. "Of course, I should give this a try. I even think I could try my nail clippers."

"I think it's necessary to test it out and see if there's any difference."

"Oh, right."

"Before I came here, I even tried to strengthen the Den Den Mushi with a strengthening stone, but I failed!"

Chapter 69 Failure is the Mother of Success

Admiral Kizaru took off his sunglasses, revealing a pair of "lewd" eyes, resembling those of a perverted middle-aged man on the subway or bus.

They are spying on each other.

His face showed no sign of seriousness whatsoever; his unshaven face gave him the carefree and roguish look of a thug.

He didn't wear sunglasses when he was a child, but as he grew up, he found that he "matured" a little too quickly.

He looks a bit older than his peers.

Kizaru picked up the enhancement stone.

I started to upgrade my sunglasses.

Under the watchful eyes of everyone.

One, two, three beads didn't form a line, but after a while, I successfully upgraded the sunglasses to +12.

Kizaru immediately put on his sunglasses, regaining his admiral-like demeanor.

The moment he put on the sunglasses, his expression changed drastically, and he exclaimed with a pout, "Wow... this is incredible, truly incredible!"

"The enhanced sunglasses have actually improved dynamic vision detection quite a bit, which really surprised me!"

His exclamation made everyone realize that the strengthening stones really did have a "magical" effect on the sunglasses.

Kizaru then tried it out using Observation Haki. "It really can enhance Observation Haki. I really like this enhancement stone. It's a truly amazing invention."

The range of perception and the speed of dynamic visual capture of Observation Haki have been greatly enhanced. Enemy movements will be slower and easier to capture under the influence of Observation Haki.

It greatly enhances combat effectiveness!

A rare smile appeared on Akainu's face, though it was a slightly stiff one with a small curve. He praised, "Hill is truly an amazing scientist, to have invented such an incredible enhancement stone."

"I never imagined that these strengthening stones would have such an effect."

In his mind, people without strength are not worthy of his approval, but now he has to admit the power of Hill Technology.

Far beyond imagination, it's simply divine skill!

"That guy Hill deserves a good reward. We'll discuss that later. Let's see if Borsalino can increase the number of times the Ame-no-Murakumo Sword can be enhanced to 13," Sengoku said with a chuckle.

The navy can no longer be described as thriving; it's changing every day, undergoing rapid transformations.

Kizaru picked up the Ame-no-Murakumo sword, which had already been upgraded to +11, just two steps away from +13.

Or rather, it's just one step away.

That means upgrading from level 12 to level 13.

With the Kusanagi Sword in one hand and a power-up stone in the other, Kizaru's power-up techniques became more practiced, mainly because he had performed many power-ups.

They were very familiar with the process.

With one enhancement stone, the Ama-no-Murakumo Sword was enhanced to level 12.

Kizaru calmly picked up another enhancement stone, though inwardly he couldn't help but feel uneasy, worried that this enhancement might fail again.

However, they lost 26 enhancement stones, worth 260 million Berries.

At this moment, Kizaru couldn't help but hold his breath, adjust his mindset, and silently chanted in his heart, "Do it for me!"

He slapped the enhancement stone in his hand toward the Kusanagi Sword.

As the light burst forth.

The enhancement has begun.

Sengoku, Akainu, Aokiji, and Vice Admiral Tsuru all stared intently at the enhancement stone, praying that the enhancement would be successful.

Even the palms of his hands started to sweat during the Warring States period.

He was eager to know how much Armament Haki could be amplified by enhancement level 13.

The light on the strengthening stone continued to shine.

From one corner.

Halfway through.

It has gradually integrated into two-thirds of the area.

Just as everyone was on the edge of their seats, thinking they were about to succeed, the light from the strengthening stone flickered.

Oops!

Everyone's hearts skipped a beat.

Even Kizaru's expression fell, becoming rather unpleasant.

next second.

Sure enough, small cracks appeared on the blade of the Kusanagi Sword and began to widen and spread.

Finally, it shattered into countless tiny fragments.

"Failed again. I've tried twice already. What are the odds of getting it to +13?" Kizaru sighed.

I was speechless and a little disappointed.

Sengoku comforted him, saying, "Perhaps the chances are a little smaller. It's not as easy as you might think. You've only failed twice."

"Besides, you can upgrade it to +12 first and use it for now. You can try it again when the next batch of upgrade stones comes out."

Two consecutive failures dealt a slight blow to everyone's enthusiasm and confidence.

Akainu's eyes flickered. "Since Borsalino has failed, why don't I take over the experiment? My gloves are level 12, so I can try it right away."

He took out a pair of gloves from his pocket. He would be very satisfied if even one of the gloves could be successfully enhanced to +13.

After all, it's not difficult to upgrade it back to +12.

Akainu picked up a strengthening stone and, without the slightest hesitation or pause, began to strengthen the glove.

The light emitted by the strengthening stone shone on everyone's face.

Although Kizaru was somewhat disappointed after failing to enhance his power twice, he was also looking forward to the result of Akainu's power-up to level 13.

The office was unusually quiet.

All eyes were focused on the enhancement stone.

Time seemed to pass very slowly, and when only the last piece of the strengthening stone remained, everyone's hearts began to pound.

next second.

The enhancement stone disappeared completely into the glove.

+13 gloves, done!

Everyone stared wide-eyed involuntarily, because the gloves in front of them had changed.

A faint fluorescent glow emanated from the gloves.

It has its own radiance, not a very strong or dazzling one, but a soft glow like moonlight.

"It's amazing that after being enhanced to level 13, the item can actually glow. That's truly amazing." Sengoku's eyes were filled with surprise and doubt.

Even after upgrading from level 12 to 13, it still has this effect.

A smile inadvertently crept onto Akainu's lips. "I originally just wanted to give it a try, but I didn't expect it to actually work. Now let me see the changes after enhancement to level 13."

Unexpectedly, I was quite lucky and successfully upgraded the gloves to +13 on my first try.

He immediately put the +13 enhanced glove on his right hand, which he was used to, clenching his fist with his five fingers, making a cracking sound from his bones.

Instantly, the Armament Haki hardened, and the entire gray-black trap completely transformed into a steel-like, shiny black.

The next instant.

Akainu's eyes lit up, and his face showed surprise and excitement. He said, "The amplification of Armament Haki is a little more than that of +12. Now it can amplify Armament Haki by about half. Moreover... now it even has an amplification in strength."

The force has increased.

He felt he had only used three-tenths of his strength, but now he estimated he had used about four-tenths.

Add Armament Haki...

Chapter 70 (See title: Fifth Update)

"Hoo~!"

Sengoku let out a breath, feeling relaxed. He had been genuinely worried that the enhancement would fail again, but the current outcome made him very satisfied and happy.

"After being enhanced to level 13, it has gained another trait that enhances strength. It's amazing." He smiled broadly, his face beaming with joy.

After being upgraded from +12 to +13, a huge change occurred.
