If Karin, after leaving the Gale Breaker, embarked on her naive sailing journey, then Sasuke's side was purely a 'path-seeking journey'.
Seeking what path?
Naturally-
"Martial Leg Heel!"
"Wolf Thrust-"
Boom!!
On the martial arts stage, the fists and heels of the two men collided, bursting with intense fluctuations of Haki.
Next to the stage, the current 'leader' of the Happo Navy, Chinjao, with his pointed head, and his other grandson, Boo, were watching alongside their subordinates.
"This guy is actually fighting evenly with big brother!"
"And these fluctuations..."
Boo wanted to say more but was cut off by his grandfather.
"Don't make a fuss, Boo."
Chinjao's face didn't have the expression of facing a great enemy like his grandson.
On the contrary, this old man, nicknamed [Chinjao the Drill], was now smiling as he watched the young man trading blows with his eldest grandson.
"Should I say, as expected of a kid personally taught by that guy Naruto? This martial talent..."
Chinjao didn't have a mindset of hoarding the Happo Navy's internal fist technique, [Hasshoken].
Otherwise, he wouldn't have taught this fist technique to Naruto back then.
-Although that was also related to Naruto helping him and owing him a big favor.
"Sai has talent, but he's too slack."
"Does he really think the next 'leader' of the Happo Navy will definitely be him after I'm gone?"
Hearing his grandfather's words, Boo and many Happo Navy's officers turned their heads in shock.
"Chief, do you want this kid from who-knows-where to be the new 'leader'?"
"Don't joke around at a time like this, Chief!"
"Yeah!"
"Shut up!!!!!"
Hearing the group of unpromising youngsters chattering in his ears, Chinjao began to feel irritated.
He directly let out a roar, Conqueror's Haki swept across the area, silencing everyone around.
Even Sai and Sasuke on the stage paused their movements.
Unlike Sai, who was intimidated, Sasuke deliberately stopped to perceive how powerful Chinjao's burst of Conqueror's Haki was.
'Hmm, not as strong as Naruto's, nor Bullet's.'
'Looks like this 'leader' is really too old now.'
But Sasuke wasn't disappointed about this.
The reason he chose to go to Kano Country in the West Blue first was to exchange fist techniques.
And also to learn the deeper 'secret principles' of Hasshoken.
Don't be fooled by Sasuke's powerful Hasshoken… that actually mostly relied on his own physical constitution, Chakra, and Devil Fruit power.
If we talk solely about fist technique proficiency, he himself might only be slightly better than this uncle named Sai in front of him.
Of course, that's already very impressive.
After all, Sai had been trained under Chinjao since childhood. At twenty-six this year, even within the entire Happo Navy, his fist technique proficiency is among the best.
Yes, this guy is only twenty-six this year, and he just looks a bit older than his age.
Unlike the relaxed Sasuke, who even had the leisure to observe Chinjao, Sai's pressure was quite substantial.
Among the current younger generation of the Happo Navy, he had no opponents. Because of this, he had developed some bit of pride and complacency.
After all, in this small pond of the West Blue, armed forces at the level of the Happo Navy could practically act with impunity as long as they didn't provoke an Emperor.
His stage belonged in the New World.
But reality slapped him too quickly.
This kid, who looked under twenty, could actually use Hasshoken on par with him... even slightly suppressing him.
And many of the other party's moves he hadn't seen before, likely self-created.
'Damn it... how could the gap be so big?'
While Sai was still feeling unwilling, Chinjao suddenly spoke up.
Everyone saw this leader, tall as a small mountain, stand up, then leap up, landing lightly on the martial arts stage.
"Alright, Sai, step back."
"Old man! What are you saying? The fight isn't over yet!"
Hearing Chinjao's words, Sai's face immediately fell.
"Idiot! Can't you see yet!"
However, Chinjao didn't indulge him at all, directly punched Sai flying.
In terms of attitude towards educating grandchildren, Chinjao was very similar to Garp.
Thump!
Caught off guard, Sai was punched away. Fortunately, Chinjao wasn't trying to injure him, and he didn't use Haki.
After Sai landed back in the spectator stands, just as he was about to say something, Chinjao spoke.
"Sai, the gap between you and this kid isn't just a little bit."
Saying this, he pointed at the ground below.
Sai and the others followed Chinjao's finger.
On Sai's side, the ground was covered with various messy footprints and crushed stones from punches and kicks.
On Sasuke's side, apart from some dust, the ground was neat as new.
Clearly, during the earlier exchange, Sasuke could not only perfectly defend every attack from Sai but even leisurely dissipate the force, not letting the battle aftermath damage the surroundings.
The difference was immediately apparent.
Now Sai couldn't say anything.
Seeing this, Chinjao didn't say more. Instead, he turned to look at Sasuke.
"Young man, your name is 'Sasuke', right?"
"Uchiha Sasuke. I'm a Ninja."
"Ninja?"
Chinjao thought of the rumors about Wano Country, then shook his head, continuing the previous topic with a friendly expression.
"Were those Hasshoken moves taught to you by that guy Naruto?"
"No."
Sasuke shook his head.
"Naruto taught the basic fist technique. And these moves-"
Saying this, Sasuke casually threw a punch. The strong fist wind vaguely transformed into ferocious wolves, frantically tearing at everything around.
"-were all self-created by me."
Feeling this perfectly integrated fist skill, Chinjao's eyes were shining.
'What an extraordinary genius!'
'When Sai was his age, forget self-creating moves, he hadn't even fully mastered the basic Hasshoken.'
'But! Such a genius wasn't my grandson! What a pity!'
"Your Hasshoken... has already reached a very high level, kid. Hasshoken at this level doesn't need further guidance."
Saying this, Chinjao raised an eyebrow.
"Or is it that you want to learn this old man's secret technique [Drill Dragon Drill Nail]?"
Hearing this, a smile appeared on Sasuke's face. Though he didn't reply, the meaning was clear.
He had indeed come here to master the Hasshoken's secret principles.
He had also executed his 'self-created' secret technique fist moves before, but those mostly used Chakra and Ninjutsu to cut corners. In terms of Hasshoken fist technique, it hadn't reached the 'pinnacle' level.
Even Naruto couldn't clearly explain the deepest fist principles of Hasshoken.
-Or rather, given his teaching ability, it would be strange if he could explain it clearly.
According to Naruto, these mysterious and profound fist principles yielded different understandings for each person.
The Hasshoken's secret principles he mastered might not necessarily suit Sasuke himself.
If he truly wanted to achieve a breakthrough based on this, he had better personally experience the original version.
Hence, this visit to the capital of Kano Country.
Seeing Chinjao showed no intention of making a move, Sasuke simply extended his hand, making a 'come here' gesture towards Chinjao, looking extremely provocative.
This scene made the surrounding Happo Navy's officers furious. Many even grabbed their weapons, ready to teach this arrogant guy a lesson.
However, Chinjao, the person involved, remained smiling, appearing not taking the bait of this provocation at all.
Originally, Chinjao was also a hot-tempered guy.
Otherwise, he wouldn't have locked horns with Garp.
But after receiving Naruto's help, this old guy's mentality had unknowingly changed a lot.
"Wanting to learn the secret principles of our Happo Navy isn't that easy."
Chinjao understood Sasuke's desire to steal techniques during battle… after all, Naruto had done the same back then.
But he had also become shrewd, not giving the other this opportunity.
Seeing this, Sasuke didn't say anything. He knew the other must have more to say.
Sure enough.
"How about this? As long as you promise to help me with one 'small favor', I will teach you this secret technique for free!"
Saying this, Chinjao smilingly made an OK gesture with his fingers, indicating it really wasn't anything troublesome.
Hearing this, the smile on Sasuke's face didn't disappear either. Instead, he asked with interest.
"Tell me about it... I have quite a bit of free time."
Unlike Karin, who was still experiencing sailing on the sea, Sasuke, relying solely on flying, had no such concerns. He had plenty of time to go wherever he wanted.
"Have you heard of... Dressrosa?"
