One Piece: Starting with Breathing Techniques

His gaze swept across the skill bar, and Kiro pondered which skills he should upgrade.

To be honest, if he had enough skill points, he would have liked to max out every single skill.

As his gaze swept across the skill bar, Kiro suddenly raised an eyebrow, noticing a somewhat unfamiliar skill among a group of familiar ones.

[Conqueror's Haki (Beginner) (Active)]

[Introduction: Born with the aura of a king, one in a million, capable of intimidating or stunning opponents with sheer power, a manifestation of the will of a top-tier powerhouse.]

[Special Effect: Conqueror's Haki Enveloping (Not Yet Unlocked)]

[Deduction requires 3000 points, and upgrading to 'Proficient' requires 100 points]

As the most unique and rare of the three types of Haki, Conqueror's Haki is definitely worth investing in.

Not to mention, if Kiro wants to become a Yonko-level powerhouse in the future, or even go further, Conqueror's Haki Entanglement is a skill he must master.

Consciousness swept across the panel.

Should I upgrade "Conqueror's Haki" (Beginner)?

Upgrading to 'Proficient' requires 100 points.

[Confirmed, points deducted...]

[Current points remaining: 321]

Before the panel notification had even finished, a terrifying aura, almost tangible, suddenly reappeared beside Kiro.

This familiar aura was undoubtedly the Conqueror's Haki that Kiro had awakened when he was in the Marine branch.

The invisible aura expanded rapidly, and it looked like it was about to affect the surrounding buildings, but it suddenly stopped and gradually contracted, returning to a range of two meters around Kilo.

Kiro wiped non-existent cold sweat from his forehead and let out a long breath.

If he hadn't reacted quickly and withdrawn his expanding Conqueror's Haki, the surrounding ordinary residents would probably have suffered.

An invisible aura emanated astonishing fluctuations, deliberately kept within a range of approximately two meters in diameter under Kilo's control.

As Kiro carefully sensed the fluctuations in the aura, he felt somewhat alarmed.

The Conqueror's Haki he's releasing now is significantly stronger than when he first awakened it.

The aura was filled with intense pressure and power, and streaks of black and red lightning flickered in the surrounding air.

After a short while, Kiro was able to skillfully control the release of Conqueror's Haki and keep it within a certain range.

In other words, Kiro has been able to control his Conqueror's Haki to target only specific enemies, thus avoiding harming friendly forces.

However, when Kiro is able to use Conqueror's Haki Entanglement, this rarest and most special type of Haki will reveal its unique and terrifying power.

As for now, it's not a bad way to clear out the underlings.

Kiro withdrew his Conqueror's Haki and turned his gaze to the thick book he had been longing for.

New skill discovered: Dragon Slayer Sword Manual (Full Text)

Have you studied to the beginner level?

[Requires 100 points] (Currently 321 points remaining)

As Kiro stroked the cover of this ancient sword manual, a sense of anticipation began to rise in his heart.

Ever since he acquired this sword manual, he has wanted to learn and master it.

Unfortunately, Kiro was short of money at the time and didn't have that many points.

Now that he has enough points, Kiro naturally won't let go of this sword manual written by the "Sword God" Shimotsuki Ryoma.

[Confirmed, points being deducted]

[Learning...]

[New skill learned: Dragon Slayer Sword Manual]

【Dragon-Slaying Sword Manual (Beginner)】

[Introduction: A sword manual personally written by Shimotsuki Ryuma, a legendary swordsman from Wano Country hundreds of years ago. It contains his lifelong understanding of swordsmanship and the various sword techniques he mastered.]

[Special Effects: Dragon's Aura (Unlocked), Dragon Blood Tempered Blade (Unlocked), Sky-Splitting (Unlocked)]

[Current points remaining: 221]

The moment the mechanical voice fell, a terrifying torrent of information, like a landslide and a tsunami, surged into the brain.

Kiro's face suddenly turned deathly pale, and he let out a muffled groan.

The amount of information was several times greater than when deducing other skills, and the dizzying pain made Kiro grit his teeth.

Countless fragmented pieces of knowledge flashed through Kilo's mind, appearing one by one.

The posture of swinging the sword, the movement of exerting force, the deep understanding of swordsmanship...

This was comparable to the lifelong learning of a master swordsman, yet it was all poured into Kiro's unsuspecting mind in an instant.

A moment later, Kiro's forehead was covered in cold sweat. He shook his head, grimacing as he recovered from the headache, his face still showing lingering fear.

"Why are they so fierce this time!?"

"I almost fainted again, but I'm enjoying a good night's sleep."

However, as he sorted out the gains he had made from studying the Dragon Slayer Sword Manual, Kiro suddenly felt that his efforts had not been in vain.

Although I didn't fully understand Ryoma's life experience contained in the Dragon Slayer Sword Manual.

However, even what he has learned so far is comparable to the life experience of an ordinary swordsman.

Various fragmented yet practical pieces of knowledge surfaced in his mind, and many of the sword-making questions that had puzzled Kilo were easily resolved.

The timing of the strike, the angle of the swing, the different ways of holding the sword...

Previously, with the help of the Transparent World, Kilo had come very close to becoming a master swordsman.

Now, with the extensive theoretical foundation provided by the Dragon Slayer Sword Manual...

With a thought, Kiro tossed a thick iron chain he found in the storeroom high into the air.

He closed his eyes and reached for the hilt of the knife with his right hand.

A sudden inspiration struck!

He felt it!

That is…

The breath of all things!

The Dragon Slayer was drawn like a thunderclap, and a dazzling blade of light suddenly flashed through the air.

Swish!

A faint whooshing sound cut through the air as the heavy iron chain suddenly snapped in two, crashing heavily to the ground and raising a cloud of dust.

Kilo picked up the chain and examined the broken edge closely. It was as smooth as a mirror, without any trace of being cut or any signs of human intervention.

Kilo sheathed the dragon-slaying sword and let out a long breath.

These signs can only mean that...

The Sword Master realm has been achieved!

A sharp glint flashed in Kilo's eyes, his gaze as sharp as a hawk's.

A sharp and intense aura rose from his body.

Unlike the domineering and powerful Conqueror's Haki, this aura is not surging, but it is extremely sharp, like a sharp sword with its sharp edge exposed, capable of intimidating the enemy's mind.

Feeling the swordsman's aura, which was different from Conqueror's Haki, a smile gradually appeared on his face.

Finally, he became a qualified swordsman.

Although it's only the most basic Iron-Cutting Realm, how many true sword masters are there in the world?

Swordsmen are often synonymous with power!

Moreover, Kiro possesses the Dragon Slayer Sword Manual and has various sword techniques from the Demon Slayer world for reference. In the future, he will naturally become a great swordsman, and even the world's greatest swordsman!

"Hawkeye, my sword is never without its weaknesses!!!"

Have you eaten?

"Didn't eat?"

"Take this sword!!!"

Of course, Kilo can only think about it for now.

After all, he is clearly no match for Hawkeye right now.

It's not too late for him to talk to Hawkeye face-to-face when he's confident he can beat him!

His consciousness returned to the panel, and Kilo's gaze locked onto the skill bar.

He had already figured out how to use the last 221 points.

【"Breathing of the Sun" (Completed)】

[Introduction: Created by the swordsman Yoriichi Tsugikuni during the Sengoku period, this is the most primitive breathing technique that can unleash the body's full potential. Its sword techniques are as fiery as the sun and have a deadly effect on dark life forms.]

[Deduction requires 150 points, and upgrading to 'Limit Break' proficiency requires 60 points]

His gaze grew increasingly intense as Kilo looked at the skill he was most proficient in, secretly filled with anticipation.

He currently has 221 points, just enough for him to raise his Sun Breathing to its limit before proceeding with further deductions.

This breathing technique is the most powerful breathing technique, bar none.

Previously, due to insufficient physical strength, Kiro had temporarily put aside the Breath of the Sun.

Now, it's time to upgrade!

Kiro's eyes shone with anticipation, filled with excitement.

He was very curious about what kind of surprises breaking the skill limit would bring him.
