One Piece: Starting with Breathing Techniques

Immediately, Ryoma raised his hand and drew his sword with lightning speed. The black sword Autumn Water turned into a blur, bringing with it a black and red sword aura, sweeping towards Kiro.

boom!

The sword energy roared, carrying with it a supreme sword intent.

His sword intent was sharp and fierce, lacking a bit of domineering power compared to Kilo's sword intent, but it was purer and more ruthless.

"Is this the sword intent that can slay dragons?" Kiro murmured to himself.

The sword energy grazed his face but passed right through, causing him no harm whatsoever.

That unparalleled sword intent was fully revealed to Kiro's senses.

Ryoma's sword strike was completely unreserved, allowing Kiro to comprehend Ryoma's sword intent in the most direct way.

He had already gained some insights during his previous sparring session with Hawkeye, and now Ryoma's unreserved, almost instructional demonstration had greatly benefited Kiro.

Just as Kiro was about to further comprehend the Dragon Horse Sword Intent, that sword intent suddenly dissipated.

Kiro opened his eyes and saw that Ryoma had already sheathed the black sword Autumn Water and was smiling.

"This is all we can do, for those who come after us."

Longma's figure gradually blurred and disappeared, and the surrounding scenery also shattered and vanished like a bubble.

"You'll have to walk the rest of the road by yourself."

As the surrounding scenery completely collapsed, Kiro found himself back in the hospital room.

"call……"

After letting out a long sigh, Kiro sat cross-legged and began to organize his insights into swordsmanship.

A moment later, he opened his eyes and looked at an iron basin in the corner of the ward.

After tossing the iron basin into the air, Kiro drew his sword and swiftly and cleanly slashed the dragon across the center of the basin.

The iron basin landed, but instead of splitting in two as expected, it made a crisp sound like a billiard ball, remaining completely intact!

Kiro chuckled softly, recalling Hawkeye's words, "Is this... the swordsmanship of a great swordsman?"

He felt that he could now sever anything he wanted to sever.

But he can also leave everything he has cut intact and unharmed.

Let the slash follow your will!

This is the level of mastery that Hawkeye was talking about back then!

Kilo nodded in satisfaction, a look of pleasure flashing in his eyes.

The feeling of becoming stronger is truly captivating!

After arranging the iron plate, Kilo's consciousness sank back into the panel.

To become a great swordsman, in addition to sword intent, Kiro also needs to master top-level dual-color Haki.

Therefore, it was only natural for Kiro to focus his attention on the two imposing auras on the panel.

【Armament Haki (Beginner)】

[Deduction requires ? points. Upgrading to 'Perfect' proficiency requires 400 points.]

【Observation Haki (Beginner)】

[Deduction requires ? points. Upgrading to 'Perfect' proficiency requires 400 points.]

Kilo was taken aback.

It takes exactly 800 points to upgrade both of the domineering abilities to perfection.

Now that he has upgraded the Dragon Slayer Sword Manual, he has exactly 804 points left.

just!

After all, in the later stages of the One Piece world, everyone possesses top-tier Haki, and Guy even said that widely circulated classic line.

"Only domineering power can overcome everything!"

This clearly demonstrates the importance of domineering presence in a battle between strong individuals!

Without hesitation, Kilo made a decisive move, choosing to upgrade both of his domineering abilities to perfection.

To avoid being overwhelmed by the flood of information, Kiro decided to first raise his Observation Haki to its peak.

【Observation Haki (Beginner)】

[Upgrading to 'Perfect' proficiency requires 400 points]

[Confirmed, points being deducted]

[Current points remaining: 404]

The next second, Kilo's senses exploded.

An unprecedented torrent of information, indescribable in words, filled Kilo's entire mind in an instant.

Perception, centered on Kilo, spread and expanded wildly outward like a wild beast breaking free of its shackles, expanding at an extremely rapid pace.

The senses spread all the way to the Revolutionary Army's strongholds and even to White Earth Island.

Countless conversations, countless images, and countless sounds converged in an instant into a terrifying torrent of information, assaulting Kiro's mind.

However, Kilo had already been exposed to the information from the panel and had gradually adapted, even developing a certain resistance.

Faced with the overwhelming flood of information, Kiro gritted his teeth and endured the excruciating pain, his consciousness adapting at lightning speed.

A moment later, Kiro gradually gathered the Observation Haki that had spread to its limit and controlled it within a few meters around his body.

"Wow, that's a really useful ability."

Feeling his keen senses, Kilo couldn't help but sigh.

His perfect Observation Haki even allowed him to clearly hear the flapping of a mosquito's wings in the room.

However, this overly sensitive hearing made Kiro frown slightly.

Swish!

Kiro pointed his fingers together like a sword and unleashed a miniature sword aura, cleaving the annoying mosquito in two.

Kilo's brow finally relaxed after the annoying buzzing stopped.

Kilo was very satisfied with the perfect level of Observation Haki he had achieved.

If he had possessed this level of Observation Haki during his previous battle with Kizaru, he would never have ended up in such a sorry state.

Now, Kilo felt that the world around him was exceptionally clear, much more transparent than before.

It was as if my vision had always been shrouded in a layer of fog, making it blurry and unclear.

Now the fog has completely dissipated, and the world is laid out clearly before him.

[Observation Haki (Perfect)]

[Description: An extraordinary perceptive ability that allows one to sense the presence, emotions, and location of living beings through intense concentration, thereby predicting their actions and foreseeing the future.]

[Special Effects: Foresight (Unlocked), Sword Domain Perception (Unlocked)]

Staring at the two special effects, Kiro scratched his head.

He knew that the former was an ability that could only be unleashed when one's Observation Haki had been cultivated to an extremely high level.

In the original work, Katakuri was one of the strongest individuals who excelled in this skill.

They can even briefly foresee future events, giving them an advantage in battle.

but……

What is the sword domain perception mentioned later?

Kiro stroked his chin, somewhat puzzled.

However, neither of these two effects has been unlocked yet, so Kilo isn't in a hurry, since he'll find out when the time comes.

Immediately afterwards, Kiro focused his attention on the Armament Haki section.

【Armament Haki (Beginner)】

[Upgrading to 'Perfect' proficiency requires 400 points]

[Confirmed, points being deducted]

[Current points remaining: 4]

As the familiar notification sound rang out, Kilo took a deep breath, his face filled with anticipation.

Suddenly, a wave of heat swept over his body, and Kilo's skin instantly turned bright red.

"hiss!"

"It doesn't hurt!"

Kiro gritted his teeth, feeling the intense heat emanating from his meridians.

A violent, invisible force surged forth, seemingly about to tear Kiro's body apart.

After about an incense stick's time, the violent power gradually subsided and was eventually completely controlled by Kiro.

Kiro raised an eyebrow, using the powerful perception gained from the return of life to sense the changes within himself.

A surging power, like a rushing river, surged within him, and an invisible energy, as if forged through countless trials and tribulations and imbued with an immortal will, flowed throughout his body.

With a mere thought, Kiro could unleash this power instantly, covering every part of his body.

Kilo tried to grasp the Dragon Slayer, his mind racing, and in just a moment, the Dragon Slayer's blade was covered with a thick layer of pitch black.

Its color is almost identical to that of the Black Blade Night that Hawkeye had previously shown.

However, it will probably take some time to refine the Dragon Slayer into a black blade.

After a while, Kiro's aura stabilized, and he had fully mastered the surging Armament Haki within his body.

An introduction popped up on the panel at the appropriate time.

Armament Haki (Perfect)

[Description: An invisible force derived from life energy that enhances personal defense and attack power. When perfected, it can defeat enemies from within, possessing limitless potential and formidable power.]

[Special Effects: Internal Destruction (Unlocked)]

Kiro's eyes lit up when he saw the special effect called "Internal Destruction".

In layman's terms, internal sabotage has a more widely known name.

It is the famous advanced Armament Haki technique, Ryuo!
