Roy quietly observed Garp's attempts from the side, lost in his own thoughts.
Seeing the difficulty Garp faced in controlling his breath, he couldn't help but feel a sense of admiration.
As expected, the power in the world of One Piece was primarily centered around brute force, with Haki being the most prominent example.
In this world, the application of Haki emphasized overwhelming aura and direct power output.
Whether it was the hardened defense of Armament Haki, the perceptive insight of Observation Haki, or the intimidating suppression of Conqueror's Haki, they were all imbued with a direct and forceful style.
In contrast, the breathing techniques from the Demon Slayer world focused on using subtle breath control to unlock the body's potential, which was fundamentally different from the power system of the One Piece world.
Hearing Roy's words, Garp silently agreed in his heart.
However, his unyielding nature only strengthened his resolve to master this breathing technique.
Gritting his teeth, a glint of determination flashed in his eyes as he adjusted his state once more.
He believed that with his years of combat experience, he could gradually adapt to this entirely new method of controlling power.
As time passed, he began to get a feel for it, and his breathing started to become more rhythmic.
Once he could complete several deep breaths relatively steadily, Garp stood up and began moving in a small area.
At first, his breathing rhythm was disrupted again, his steps unable to coordinate with his breath.
But Garp possessed tenacious perseverance and a strong learning ability; he continuously adjusted his movements and breathing, and gradually, he was able to maintain a relatively stable breathing pattern even while moving.
Witnessing Garp's progress, Roy thought to himself, *Garp truly is someone with exceptional talent in physical combat, possessing an incredible ability to adapt.*
...
Recalling the breathing technique Roy had taught him earlier, Garp took a deep breath and began to regulate his breath according to its rhythm.
His chest rose and fell slowly, his breath flowing in and out of his lungs like a gentle stream, steady and smooth.
With the rhythm of his breathing, he could feel a warm current slowly flowing through his body, as if activating every cell within him.
Just as his breathing reached its optimal state, Garp let out a sudden low shout, his right fist shooting forward with lightning speed.
This punch carried a howling wind, cutting through the surrounding air.
Although there wasn't much difference in raw power compared to the punches he usually threw relying on his immense physical strength and Haki, the speed and fluidity of this punch were noticeably improved.
It possessed a smoothness like drifting clouds and flowing water, as if there were no obstructions between his arm and body, allowing power to be transmitted from his body to his fist without any loss.
Garp himself keenly perceived this marvelous change, his eyes instantly lighting up with an excited smile on his face.
"This power is quite interesting," he said, his voice tinged with excitement, as if he had discovered a new treasure.
In Garp's view, the change brought about by this breathing technique was not only an improvement in punching speed and fluidity but also a completely new approach to combat.
For a long time, he had relied on his overwhelmingly powerful Haki and immense physical strength in battle, overcoming force with force, charging forward without hesitation.
However, this newfound control over his breath opened a new door for him.
Sometimes, a breakthrough was like being separated by a thin sheet of paper; a single touch could lead to sudden enlightenment.
"This breathing technique, though seemingly simple as just controlling one's breath, contains such profound principles."
Garp narrowed his eyes slightly, a thoughtful expression appearing on his face as he spoke slowly,
"My past battles relied solely on brute force. But this breathing technique emphasizes using softness to overcome hardness, leveraging momentum to exert power. It's like water, which appears weak yet can seep into every crevice."
Garp understood that he had reached the pinnacle of his direct, forceful combat style, a level almost unmatched by anyone.
But now, if he could also perfectly master this breath control, it might, in turn, nourish and enhance his original strength.
Given his current level of power, even the slightest breakthrough could lead to earth-shattering changes, giving him a significant advantage in battle.
A bold idea emerged in his mind:
If he could skillfully combine the hardness of Haki with the suppleness of the breathing technique, what astonishing results would that yield?
Perhaps he could create an entirely new, even more powerful fighting style, making him invincible across these seas.
Thinking of this, a surge of uncontrollable excitement welled up in Garp's heart, his hands unconsciously clenching as he eagerly anticipated testing his ideas in actual combat.
"Maybe this is the opportunity for me to surpass my limits. By merging the hardness of Haki with the suppleness of the breathing technique, combining hardness and softness, I can surely elevate my strength to the next level."
Garp muttered to himself, a resolute gleam shining in his eyes.
...
Garp returned to his own courtyard to begin experimenting with this newfound power.
Watching Garp's absorbed demeanor, Roy couldn't help but smile faintly.
*It seems teaching Garp the breathing technique was indeed the right choice.*
Roy murmured to himself, a hint of certainty in his voice.
He knew well that Garp possessed exceptional talent in physical combat.
"A physical combat genius like him might truly be able to master this breathing technique completely."
Roy's eyes sparkled as he continued to muse.
An image surfaced in his mind of Garp perfectly integrating the breathing technique with his Haki and physical abilities, filling him with anticipation for Garp's future strength.
Roy gently picked up his teacup, took a slow sip, savoring the faint tea fragrance spreading in his mouth.
Then, he shifted his attention from Garp to the chat group.
At that moment, the scene in the chat group switched to the Naruto world, where Sasuke was standing in an open training ground, having started a live broadcast.
Sasuke didn't mind others watching his training.
On the contrary, he hoped this method would motivate him to constantly improve.
On the training ground, Sasuke relentlessly honed his physical body.
He adeptly executed various techniques from the Marine Rokushiki, using *Soru* to leave a trail of afterimages across the training ground in an instant.
Simultaneously, Sasuke was continuously polishing his Armament Haki.
A faint black glow gradually surfaced on his arms; though his Armament Haki was still in its early stages, the glow not yet fully radiant, it was clear his strength was steadily increasing.
Roy focused on watching Sasuke's training footage in the chat group, appreciating the young man's dedication.
Sasuke was completely immersed in his high-intensity training, sweat streaming down his cheeks.
However, in the midst of executing a Soru with a sideways dodge, his expression suddenly changed.
Using his keen Observation Haki, he detected a faint, unfamiliar, and eerie presence.
"Who's there?"
