One Piece: Starting with Breathing Techniques

After calming down a bit, Kiro organized all the skills he currently possessed.

Now that his combat system is nearing completion, he no longer needs to use deduction, so he plans to use all his points on upgrading his proficiency.

First, the two most important sword techniques, [Burning Heaven and Boiling Sea Technique] and [Dragon Slaying Sword Manual], have both reached the [Mastery] proficiency level.

To upgrade to [Perfect], you need 800 points.

Upon seeing this number, Kiro gasped.

Compared to the original cost of [Breathing of the Sun], the upgrade costs of [Burning Heaven and Boiling Sea Technique] and [Dragon Slaying Sword Manual] have increased several times over.

Even though he currently has 1482 points, it seems he needs to allocate them wisely and make rational choices when upgrading.

Both [Breath of the Gale] and [Thunderclap] are at the [Proficiency] level, and upgrading them also requires 100 points.

As for the Haki type, both types of Haki have reached "Perfect," while "Conqueror's Haki" is at "Proficient."

Both types of Haki require 400 points to reach the "Perfect" level, but "Conqueror's Haki" requires a full 500 points, which is significantly higher.

However, Kiro speculated that if he mastered the "Perfect" level of Conqueror's Haki, he might be able to master the ultimate technique of Conqueror's Haki, which is...

Conqueror's Haki envelops you!

Dragon had previously demonstrated this destructive power at the Revolutionary Army training base, and Kiro still remembers it vividly.

He currently has enough points to upgrade his [Conqueror's Haki]!

However, Kilo didn't rush to upgrade on the spot, but instead turned his attention back to the skill bar.

Compared to swordsmanship and domineering aura, physical skills/skills do not need to be allocated points for the time being.

[Spots] have already reached their limit and there is currently no room for further improvement, so they are not within Kilo's consideration.

After reviewing all the skills he currently possessed, Kiro began to ponder.

He is about to travel to the Holy Land of Mary Geoise, and his immediate priority is to improve his existing combat strength.

Although, according to the plan, this operation was theoretically not very dangerous.

Given the precedent set by Fishman Tiger, the Revolutionary Army's operation should proceed just as smoothly, right?

"Ouch, this is bad!"

"How did I end up jinxing myself?!"

Suddenly realizing what was happening, Kiro gasped, shook his head, and dismissed the thought.

With battle imminent, he couldn't afford to act like a general on a theatrical stage, planting a flag for himself.

After a moment's thought, Kilo finally made a decision.

Now that I've decided to focus on swordsmanship, improving my Dragon Slayer Sword Manual is undoubtedly the best choice.

This will most directly solidify his foundation in swordsmanship, allowing him to take another step forward in cultivating sword intent.

Perhaps he can use this opportunity to condense his own sword intent?

Since the [Dragon Slayer Sword Manual] requires 800 points, he now only has 682 points left out of his 1482 points.

Since it's not enough to upgrade [Burning Heaven and Boiling Sea Technique], Kiro is preparing to upgrade [Conqueror's Haki].

He has long coveted Conqueror's Haki.

This will require another 500 points, so Kilo plans to use the remaining 182 points on [Breath of the Gale].

Although he is not using this once-dominant sword technique in his current battles, the practicality of [Breath of the Gale] is undeniable.

Whether gliding through the air on a hurricane or propelling a small boat like this, the [Breath of the Gale] plays a crucial role.

Furthermore, the second effect of [Breath of the Gale] is called [Riding the Wind].

As the name suggests, it allows Kilo to fly freely in the air by using strong winds.

If this effect can be unlocked, Kilo's mobility will be greatly improved.

Although Moonwalk has the same effect, it is less flexible and aesthetically pleasing, and you need to step up and down in the air to stay airborne.

Upgrading [Breath of the Gale] requires 150 points, and the remaining points are just enough.

"Phew~~~"

Kilo breathed a sigh of relief and decided to start with the simpler parts first.

He still vividly remembered the scene of fainting while upgrading his skills last time, and he didn't want to repeat the same mistake.

【"Breath of the Gale" (Proficient)】

[Upgrading to 'Mastery' skill level requires 150 points]

[Confirmed, points being deducted]

[Current points remaining: 1332]

The next moment, as a flood of information rushed into his mind, Kiro felt a distinct heat coursing through his meridians.

The insights gained from more than ten years of arduous practice were quickly digested and absorbed, ultimately transforming into the purest techniques and experience.

He gripped the Dragon Slayer sword, and his skillful muscle memory immediately surfaced, bringing to mind the essence of the Gale Breath sword technique and the skill of controlling the wind.

In the instant of the ascent, he felt his body suddenly become lighter, and his muscles, which had been as heavy as steel, suddenly became lighter.

Upon closer inspection, he realized that the gust of wind around him was lifting his body to achieve the effect of reducing his weight.

[Unlocked effect: Riding the wind]

【Riding the Wind: One can harness the wind and travel freely through the air. One can traverse thousands of miles on the wind, moving freely through the air, appearing and disappearing without a trace.】

As Kiro relaxed all his muscles, a thought flashed through his mind, and the aura around him suddenly intensified, enveloping his body and lifting him upwards.

Under Kilo's slightly surprised gaze, his feet gradually left the small boat, and his whole body slowly floated above the boat.

For a moment, he seemed to defy gravity, standing tall in the air surrounded by a riot of wind and flowers.

In an instant, he moved swiftly forward along the sea, so fast that he left the small boat far behind.

Kilo sped forward, then with a sudden thought, his figure abruptly turned, making a sharp, physics-defying turn.

Is this the mobility of riding the wind?!

However, this kind of change of direction requires extremely high physical fitness, and only his current physical strength can adapt to it.

The howling wind grew louder, and the howling gale swept across the boundless blue sea.

After leaving countless afterimages in the air, Kilo nodded in satisfaction, a smile playing on his lips, and gradually flew back to the small boat.

The effect of "Riding the Wind" was even more powerful than he had imagined. Combined with his current physique, it raised his mobility in actual combat to a whole new level!

If he were to go back and fight Kizaru again, he would never be in such a sorry state, and he would never have to take the opponent's Yasakani no Magatama head-on on the ground.

After mastering the [Breath of the Gale] technique, Kiro discovered that his ability to manipulate the wind had also been significantly enhanced.

As Kilo increased the wind force propelling the boat to its maximum, the boat's speed suddenly increased by half!

If someone were to observe from a distance, they would probably mistake the small boat for a speedboat and would never guess that it is just a small wooden boat without a motor!

At the current pace, Kilo should be able to reach the Holy Land of Mary Geoise in about a week!

Kilo nodded in satisfaction, then turned his gaze to the next skill to be improved.
