Marineford in Sharingan, Uchiha Admiral

Boom-!

Boom-!

Boom-!

Outside the oval-shaped naval training ground, it looked as if two Tyrannosaurus Rex were colliding, causing dust to billow and seabirds to fly in disarray.

In the field.

Zefa was shirtless, his arms like pure black granite, and the muscle lines on his back resembled those of a ferocious beast, roaring silently.

He glanced down at Allen in front of him, his voice calm yet carrying an overwhelming domineering presence.

"Is this all you've accomplished in the past six months? That's too slow!"

Before he finished speaking, Zefa's figure had already left an afterimage in the same spot.

Allen's face turned ashen, his pupils contracted sharply, and he instinctively swung his whip-fist, only to hit nothing but air.

"You rely too much on your eyes, kid!"

Zefa's voice came from the other side, along with a massive, overwhelming fist!

……

brush--

Allen's body twisted in a way that defied logic, his lower body remaining still. The whip-like punch he had thrown seemed to spin around at an incredible speed, making it appear as if he had been gathering power for the previous blow.

*Smack!*

With a sonic boom, Allen pushed forward with both palms, his hands covered in black, barely managing to block Zephyr's giant fist.

"If you had eyes like mine, you definitely wouldn't say something like that."

Allen parted his lips slightly, and the tomoe in his crimson Sharingan eyes swirled.

"I can see your movements perfectly clearly now, Professor Zephyr!!"

……

"yes……"

Zefa snorted coldly, and the black on his arm seemed to deepen even further.

Boom! ...

A tremendous force surged through him, and the black color covering Allen's hands faded away like ink being washed away. He staggered back several steps, his tiger's mouth splitting open and bleeding.

Allen gritted his teeth and lowered his waist, once again mobilizing his Armament Haki. This time, he could narrow the range and concentrate the Haki in his palm.

Peng! ! ! !

It was another palm strike against a fist.

After a brief pause...

Boom boom boom boom boom boom boom boom!

Fists, palms, and fingers—countless impacts rained down like a storm of pear blossoms, shattering Allen's carefully gathered Armament Haki.

"Armament Haki isn't like mud; if you can't gather it, don't use it!!"

……

It has been six months since Allen entered the training camp.

In the first month, he had a basic grasp of Armament Haki.

Unlike Conqueror's Haki, Armament Haki is a power hidden within the human body, temporarily referred to as "ki".

Through high-intensity, extreme physical training and actual combat, once you can clearly perceive this energy, you can try to manipulate it with your mind.

Armament Haki is essentially the body's own energy, much like the "true qi protecting the body" in martial arts and qigong, which is similar to the envelopment of Armament Haki.

The advanced technique for using Armament Haki, known as "Ryuo" in Wano Country, involves infiltrating this aura into the opponent's body to cause internal damage, also known as "True Qi Enters the Body".

Using Armament Haki for a wide-range attack is even better described as "releasing true energy outwards".

……

Learning and applying are two different things.

Many naval officers have also learned Armament Haki, but it is completely unusable in actual combat; at best, it is just a "harder block of iron".

Although Allen's Armament Haki crossed the threshold, Zephyr was the man sitting almost at the end of the road.

The difference in purity between the two is too great, resulting in Allen being completely outmatched.

After countless rounds, Allen's breathing became increasingly heavy, and the Armament Haki on his fists subtly changed with each break and reunion.

Allen constantly adjusted his movements amidst the relentless onslaught, gradually shifting from being on the defensive to being able to fight back.

His brain was racing, as if his soul had left his body, watching his own battle with Zephyr from an outsider's perspective.

……

Allen suddenly realized a problem.

He likened Conqueror's Haki to chakra, saying that the two powers are similar in essence.

Armament Haki is essentially just body energy, and its operation is much simpler than that of chakra.

It's like a kind of...

Strengthen the bloodline limit of physical beings!

Yup!

Why would I treat Armament Haki as a separate power system? My greatest strength lies in combining the powers of both worlds to develop the power that best suits me!

The combination of Ice Release and Devil Fruits makes the activation of techniques more powerful and faster, with most techniques not requiring a charging phase.

Armament Haki invasion techniques...

I already knew how to do it!

Whether it was the invasion of eye power or the ice release technique used against the hunter, these techniques were both demonstrated.

……

This can be considered...

Is it simply because I'm in the midst of it all...?

It took me half a year to understand something so simple!

-

The use of Armament Haki is to use one's will to mobilize the body's abilities, turning the intangible into the tangible.

In the ninja world, why are ninjas particularly wary of those who use eye techniques?

Because the activation of pupil techniques is extremely secretive and impossible to defend against!

Fear because it is invisible!

Once you understand one thing, you understand everything. Allen began to try to control Armament Haki with his eye power. This extreme mental exertion caused steam to rise from the top of his head.

……

Ok?

Zephyr raised an eyebrow, noticing the change in Allen's movements.

It must be said that Allen was the most capable learner among the recruits he trained!

Even monsters like Sakazuki can't compare to Allen in this respect!

If it weren't for this guy insisting on being escorted before he'd participate in daily training, his laziness was ingrained in his bones, he sometimes inexplicably spouted wild remarks, he was picky about what he ate, and he liked to bully his fellow recruits, especially the very hardworking Dor...

Eliminate a series of drawbacks.

Allen was arguably his most successful disciple.

……

During their weekly sparring sessions, he could feel Allen's progress, and it seemed like there was no bottleneck in his improvement!

He sighed inwardly more than once.

This guy... is a monster just like Garp!

……

Decades ago, before the Great Pirate Era began, the number of pirates was far less than it is today, but their quality was much higher.

Those who were able to stand out in that era were all beings who could be called monsters.

Even in that era, Garp, with his iron fists, fought his way from the four seas to the Grand Line, never suffering a defeat!

The Navy's undefeated hero is not only a nightmare hanging over all pirates, but also a mountain towering over his contemporaries.

Even the Sengoku period, who possessed Conqueror's Haki, was only known for his wisdom; one can only imagine how terrifying his fists must have been.

Zephyr was also a former Navy Admiral, but he was well aware of the gap between himself and Garp.

His limit is Admiral, but that title is something Garp disdains to possess.

……

When he realized he could no longer teach Kuzan, it was he who recommended Garp to him.

He predicted that perhaps soon he would have nothing left to teach Allen.

With this mindset, Zefa gradually increased his strength during the sparring session, wanting to see the limits of this kid's growth.

this time……

Not quite the same...

The idea was that Allen's Armament Haki would harden with each blow, but...

In the midst of the fierce clashes and the barrage of Armament Haki, Zephyr sensed something extremely cold and sinister seeping into his Armament Haki.

……

interesting!

A hint of interest flashed in Zefa's eyes. He raised his fist and unleashed a powerful punch accompanied by a shockwave.

The jet-black fist fell, seemingly shattering space itself!

"Crushing Impact!"

For the first time, Zephyr used a move!

-

On the stands of the martial arts arena, several figures of varying heights stood.

Among them were Marine Admiral Kizaru and Vice Admiral Aokiji, who is rumored to be about to be promoted to Admiral.

A major general standing nearby exclaimed, "Using such a move in sparring! Is Teacher Zephyr trying to kill Allen?!"

He quickly turned to look at Kizaru: "Admiral Borsalino!!"

Kizaru and Aokiji remained silent, watching the scene unfold.

Only when their power reached their level did they realize that Allen was undergoing a transformation and that what he needed was Zephyr's impact.

……

……

……

As the fist drew ever closer, Allen felt as if everything around him had lost its color.

Then, even the wind stopped.

The Sharingan emitted an eerie red light, its three tomoe spinning rapidly. Its ocular power intertwined, entwined, and merged with the thick, steel-like Armament Haki within its body—

Black and red light seeped from beneath the skin, rendering scarlet patterns on the black metal layer, like blood vessels pulsating in black iron.

……

Peng——

The fist shattered Allen, reducing him to ashes.

The next instant, Allen appeared as if he had teleported right next to Zephyr...

Whoosh!!

The black and red fist struck Zefa in the abdomen.

-

-

silent.

The first time, Zephyr was driven back.

……

The onlookers were silent, watching Allen, who was submerged in black and red in the center of the training ground and looked like a demon, and a chill suddenly rose in their hearts.

……

-

The fusion of Yin Release chakra and Armament Haki, I've named it—

Armament Haki - Dark Entanglement!
