"Alright, I've finished explaining the basic theories. Hmm... there's nothing more to teach!"
Luffy clapped his hands, surprisingly intending to end the lesson like this.
This guy was truly a teacher for the first time. He believed in "the master leading the way, cultivation is up to the individual."
Honestly, that's how he himself learned back then. Except for the part about not hurting his own disciples.
When Rayleigh taught Luffy the three types of Haki, he directly put him on a Grand Line island teeming with ferocious beasts, and each with formidable strength. If it were an ordinary person, they wouldn't survive an hour.
But Luffy actually studied there for two whole years, constantly tempering his Haki in actual combat.
His half-year wasn't wasted. He finally achieved significant improvement, his entire being feeling as if he had undergone a complete transformation!
If he could do it, then people in this world should also be able to do it.
After all, it's different from chakra, this kind of energy that has a "nature"...
Even now, Luffy hasn't sensed any of what the ninjas call "chakra" power.
He doesn't know if he hasn't found the trick, or if he himself isn't a native of this world, so he's suppressed by this world's rules.
In short, wanting to figure out what chakra is all about is probably not possible for Luffy in a short time.
On the other hand, the ninjas in the ninja world.
Luffy felt that perhaps they could unleash the taijutsu techniques from their own world, and even Haki abilities!
After all, neither taijutsu techniques nor Haki abilities had any restrictions.
Even ordinary people, as long as they put in the effort, could grasp the basics.
However, the final result and achievements depended on individual talent.
Luffy didn't understand how to observe what was called "talent" in people, but he had a special intuition. He just felt that these two young ninjas in front of him would definitely achieve extraordinary things in the future.
So that means, the two of them might each possess different powerful talents!
"Mr. Luffy! Mr. Luffy! Is that all...? We, can we train now?" Naruto ran over and asked.
"Of course!"
Luffy nodded as a matter of course.
"Or do you want something else? Or do you need me to go catch some fierce wild beasts for you to fight?"
"After all, it's in actual combat that you can maximize your fastest mastery of the power you possess, isn't it?"
The logic Luffy spoke of actually applied in the ninja world as well. Practice was the only standard for verifying truth.
Even learning ninjutsu and taijutsu, it still required achieving results in actual combat to be considered complete.
But right now, where could Sasuke and Naruto find opponents?
Simply, be each other's opponents and start training directly!
Sasuke and Naruto had been at odds since they started ninja academy.
The root cause was actually still because of the little girl.
But that didn't matter. That was just the beginning of the story.
The rivalry between Uzumaki Naruto and Uchiha Sasuke hadn't subsided yet, and they were still secretly competing.
No matter what, the two of them would always compete to be better.
Especially Uzumaki Naruto, from any angle, he didn't want to lose to Sasuke.
"I'll say this in advance! During your sparring match, you are not allowed to use any ninjutsu you've previously mastered!" Luffy reminded them.
"After all, this is a test of mastering Haki. Only mastering Haki is considered success. The degree of mastery, whether it's the combat power and destructive power unleashed is high or low."
"Understood!" Naruto was already rubbing his palms. Sasuke was also eager to try.
"Then..." Luffy looked at the two little ones. "Start now!"
Naruto and Sasuke immediately clashed, fist to flesh. It was a complete close-quarters brawl!
Luffy could actually tell that these two little ones were trying to use Armament Haki to attack and Observation Haki to block the enemy's moves.
Unfortunately, they had just learned the theory. It was impossible for it to have a very obvious effect one minute later in actual practice.
Unless it was truly a thousand years, or even ten thousand years of medical treatment.
So naturally, in this battle, Naruto and Sasuke both ended up with black eyes and bruises. Neither held back when fighting.
But did they truly learn anything? Not really...
"Very good!" Luffy gave a relatively positive affirmation. "Explore slowly. There's no rush for this."
"How could you have possibly imagined what I experienced to grasp these powers...?"
Back then on that isolated island, the one who taught Luffy to injure himself was none other than the Pirate King's right-hand man, Dark King Rayleigh!
A truly living legend. In the world of One Piece, his pure combat ability and destructive power were also top-tier existences.
Compared to being beaten up by Rayleigh, a little skirmish between two children, where they hit each other back and forth, was truly just child's play.
"Look how happy you all are now... and you have companions... and companions by your side."
As he spoke, Luffy recalled his companions and the important things in his original world.
"Adventure or go home? Going home is an adventure..." he murmured, then turned his head to his resting place.
Naruto and Sasuke both got up early and rushed over to learn something new.
Everyone returned home covered in injuries.
To be honest, their understanding indeed grew tonight. They learned that there were experts other than ninjas, systems other than ninjutsu, and other powerful forces.
But truly wanting to master this new power, for these two children, how easy could it be?!
They could even understand this matter, which itself was already an extraordinary talent!
...
"Were you discovered by that guy?"
Konoha Anbu, within the root organization. Danzō was sitting before his desk, where the ninjas he had sent to find trouble with Luffy tonight were lined up.
"Yes."
"We concealed ourselves very well. Even the Anbu ninja escorting him back couldn't detect us."
"But he saw our location with one glance..."
"He even pointed out the precise location of each and every one of us, judging by his gaze!"
"Mm..." Danzō closed his remaining eye.
"Alright, you can all leave now. Don't tell anyone about this matter!"
"Yes!" The Anbu ninjas instantly vanished from sight, as if melting into the ubiquitous shadows around them.
"Luffy... Luffy..."
Danzō had suffered greatly at Luffy's hands before, taking a huge fall! Why wouldn't he want to get his revenge? Five!
