Kilo focused, and a line of small text gradually appeared under [Deduction].
[Deduction: Evolve an already mastered skill while inheriting the original skill's characteristics]
[Note: The new skill after Deduction will inherit a portion of the original skill's proficiency]
Kilo was startled, sized up his skill bar, and fell into deep thought.
Speaking of his strongest skill, it was naturally the Pattern, but the side effects of the Pattern were too great. His current physique simply couldn't withstand it; the white hair on his head now was a good example.
At the thought of this, Kilo felt a bit of a headache. Previously, in order to escape from Aokiji, he had no choice but to activate the Pattern, overdrawing more than half of this body's vitality.
It seemed he would have to look out for ways to replenish his vitality later.
Moving his gaze away from [Pattern], Kilo looked at the densely packed Breathing Styles, feeling somewhat conflicted.
Since the new skill after Deduction would inherit part of the original proficiency, then [Sun Breathing] at Perfect proficiency and [Wind Breathing] and [Thunder Breathing] at Great Success should be prioritized.
The other skills were basically at Small Success or Proficient; the proficiency after Deduction would likely be pitifully low.
For Kilo, who was anxious to convert points into current combat power, this was clearly out of consideration.
His gaze swept back and forth between [Sun Breathing], [Wind Breathing], and [Thunder Breathing], and Kilo frowned.
Theoretically, the only one at Perfect proficiency, [Sun Breathing], was undoubtedly the first choice, but Sun Breathing contained power close to the sun, the load of using it was enormous, and it had high requirements for the user's physique.
In demon slayer, a large part of the reason why this Breathing Style was lost was that the vast majority of users could not bear the load and found it difficult to master, eventually leading to its gradual disappearance.
Fortunately, the Kamado family passed down the Hinokami Kagura from generation to generation, which gave Kilo the opportunity to learn Sun Breathing.
In the current situation, Sun Breathing, which has high requirements for physique, is clearly unsuitable.
And the shortcomings of [Thunder Breathing] are equally obvious; this Breathing Style emphasizes Extreme Speed and instantaneous explosive power.
But in the Pirate World where everyone is a health tank, it's hard for this kind of Breathing Style to handle all scenarios.
That leaves only...
Kilo looked at [Wind Breathing]. This Breathing Style fits his fighting style very well; most sword techniques lean towards offense, but it doesn't lack defensive moves.
And most importantly, [Wind Breathing] does not have as high a physical requirement as the other Breathing Styles, making it undoubtedly the most suitable for the current situation.
The familiar cold mechanical voice sounded.
[Do you wish to deduce "Wind Breathing"?]
[This Deduction requires 50 points]
Thinking that this was already the best choice at the moment, Kilo moved his consciousness.
[Confirmed, deducting points]
[Current points remaining: 17]
[Deducing...]
[Deduction complete, new skill learned: Breath of Gale]
[Breath of Gale (Proficient)]
[Description: Deduced from the Wind Breathing style in the demon slayer: kimetsu no yaiba world. Its power is significantly enhanced compared to the original Breathing Style, and it can release materialized hurricanes when performing sword techniques, with a maximum distance of 15 meters.]
[Special Effects: Extreme Speed (Passive, Unlocked), Wind Riding (Passive, Locked), Dark Wind Domain (Active, Locked)]
[Points required for upgrade: 100]
The moment the Deduction ended, Kilo grabbed his head and let out a muffled groan.
A massive amount of memories of practicing swordsmanship were frantically flooding into his mind, as if he had spent countless days and nights without rest, without eating or drinking, wholeheartedly comprehending and developing Wind Breathing, combining all his martial arts experience, spending decades, and finally deducing the martial art named Breath of Gale.
At the same time, a large surge of warmth suddenly emerged from his heart, flowing through his meridians to his whole body, constantly repairing muscle damage.
After two or three minutes, Kilo slowly rubbed his head and recovered.
"Hiss... is deducing martial arts this dangerous? I almost fainted again!"
A moment later, sensing the newly learned moves, a smile appeared on Kilo's face.
The sword techniques in Breath of Gale retained their original names, but their power was worlds apart.
And, most importantly...
Kilo flipped his right hand, and a green hurricane appeared in his palm.
With a thought, the hurricane actually detached from him, floated out the window, hit the wall after floating about ten meters, and dissipated with a bang.
Looking back at the wall, crisscrossing fine marks had actually appeared.
Kilo was somewhat dumbfounded by the sight. You should know that with the original Wind Breathing, only after he reached Great Success could he barely summon a physical hurricane around his body, and once it left his vicinity, it would immediately dissipate.
Even with the cooperation of sword techniques, it couldn't extend more than ten meters, let alone this kind of distance.
In actual combat, releasing the hurricane could also cooperate with Kilo's own actions, making it extremely practical!
While learning Breath of Gale, a warm current washed over his injuries from the inside out. Although he hadn't fully recovered, he was mostly better, at least not affecting normal combat.
Moreover, Breath of Gale inherited the original proficiency and is now [Proficient], unlocking a type of special effect called [Extreme Speed].
Special effects are something only powerful skills possess. Although Kilo has many skills, only Pattern and Sun Breathing have special effects among them, and the requirements for proficiency are also very high.
At least he hadn't unlocked them yet.
And the current points were clearly not enough for upgrading or Deduction. Kilo planned to save points first; there would definitely be many places where points would be needed later.
Closing the panel, he slowly opened his eyes, a sharp light flashing within them.
Standing up, he only felt his whole body as relaxed as if he had been reborn, his body feeling light, which must be the effect of the [Extreme Speed] special effect.
Feeling it carefully, Kilo found that the [Extreme Speed] special effect could increase his speed by about thirty percent, including movement speed and attack speed.
This kind of improvement can be described as exaggerated. You should know that in actual combat, being ten percent faster is a huge improvement, let alone thirty percent!
And even the most basic [Extreme Speed] was this powerful. Kilo was looking forward to the yet-to-be-unlocked [Wind Riding] and [Dark Wind Domain], wondering how powerful they would be.
Walking a few steps to the window of the room, Kilo narrowed his eyes and looked at the scene outside against the sunlight pouring into the room.
He was currently in a small inn. Looking far into the distance, the azure sea level could be seen shimmering under the sunlight.
The original work mentioned that the young Robin last appeared on a passenger ship from a distant island in the northeast, and then vanished.
She was probably hiding on this very island.
It was early morning, and the early sun was rising in the east.
Looking from afar, the morning mist shrouded the bustling town, and the streets filled with traffic were full of the breath of life.
Looking down, many shops on the street had already set up small stalls. Kilo looked to the right, and his gaze suddenly fixed.
He saw a familiar girl's figure waiting patiently in front of a breakfast stall not far away.
A curve hooked at the corner of his mouth. In a pleasant mood, Kilo picked up the long sword by the bed that had been carefully wiped, flashed out of the window, and landed on the street, causing several cries of surprise.
Quietly coming to Robin's side, Kilo's sudden appearance startled Robin, who was waiting for breakfast.
"Wait, Kilo! Your injuries are very serious, you can't walk around so soon!"
Before she could finish, Kilo didn't argue but instead showed his right arm, which was still covered in scars yesterday.
That arm, which was originally full of wounds, was now as good as new, with no trace of injury at all.
"Didn't I say? I also have powerful abilities, this little injury is just a small matter to me!"
Kilo took the bread handed over by the breakfast stall owner and sat aside with Robin to eat.
Although Kilo said so, Robin was clearly still a bit worried.
Kilo was her only friend now. Only the two of them from the entire Ohara had survived. She didn't want to lose this friend.
As the morning sun rose high into the sky, the street beside them gradually became lively. Kilo looked at Robin, who was looking at him with concern, and suddenly felt some emotion.
Speaking of his favorite characters in the Pirate King world, there would be many choices.
The generous Nami and Hancock, the pure Vivi, as well as Yamato, Reiju, Kalifa...
But if he were to say which character he felt most sorry for, the only choice would be Robin.
This little girl in front of him was only eight years old, yet she had to survive on a world full of malice while being wanted with a bounty.
Moreover, too many heavy things had happened during this time. Her hometown was destroyed, her mother, whom she had just reunited with, died in an instant, and her new giant friend was also in grave danger to protect her.
And she herself was to be wanted because of the archaeological knowledge she cherished as a treasure, and could only live in the shadows for a lifetime.
If Luffy hadn't brought her onto the ship, Robin would probably have ended her life in pain.
Looking at Robin eating bread in small bites, Kilo made up his mind.
Since he had come, he would not let this girl fall into such a tragic fate.
Finishing the bread in two or three bites, he began to calculate his future plans.
The power in the Pirate World is much stronger than in the demon slayer world.
But this gap made Kilo faintly excited.
With the panel's existence, he believed he would slowly grow into a top powerhouse in this world.
Becoming stronger was just a matter of time for him.
