"Wow! This... how did he do that?!" Naruto's eyeballs nearly popped out in surprise!
Ninjas can also sense the enemy's chakra to determine numbers, positions, movements, and so on.
However, to determine precise movements, and even future actions, is not something ordinary chakra sensing can achieve.
Looking across the entire ninja world, only the Hyūga clan, with their bloodline limit talent—the Byakugan possesses this power.
The Byakugan can see through appearances to perceive the essence. It can directly see the ninja's internal chakra pathways.
It can even use this method to perform their Hyūga clan's ancestral martial art, "Gentle Fist."
By pinpointing chakra points, it intercepts the flow of chakra within the target's body, causing damage.
No ninja can hide their chakra under the observation of the Hyūga clan's Byakugan.
And now, the power Luffy displayed, which could sense the enemy's movements without even needing eyes, what kind of technique was this?!
"This is how Observation Haki works." Luffy nodded gently, crossing his arms.
"You just need to calm your mind and sense the enemy's attacks. Slowly, you'll be able to perceive a little."
"After that, no matter if the enemy is in your line of sight or not, you can perceive them in advance through Observation Haki and react."
Saying this, Luffy then had Naruto try throwing small stones again.
Indeed, as Luffy said, whether he closed his eyes, turned his back, or stood facing him,
the stones Naruto threw didn't even graze his clothes!
"Observation Haki is very powerful!"
Luffy suddenly thought of something, his expression becoming serious.
"If someone truly has talent in this area, they can even train Observation Haki to the point of seeing into the future in a short period!"
Luffy recalled a past opponent he had met on the Grand Line.
He could use Observation Haki to predict the future, seeing the enemy's movements a few seconds later.
A few seconds, that's right, only a few seconds. It might not sound like much.
But in a top-level showdown between true experts, being able to see a few seconds into the future could save one's life... or cause absolute lethal damage!
The most crucial thing was that this guy usually didn't use Observation Haki in combat, and his Haki was so powerful.
He could even, when communicating face-to-face with others, speak what the other party wanted to say one step ahead, imitating the actions the other party wanted to do!
"This... Kakashi-sensei's copying ability also seems capable of similar things!"
Naruto gasped in his heart. Kakashi's title "Copy Ninja" was indeed quite widespread in the ninja world.
And the reason Kakashi could copy enemy ninjutsu and even release them one step ahead of the enemy was precisely because of his Sharingan.
The power of the Sharingan allowed a ninja who possessed it to clearly see the enemy's movements, clearly see the enemy's hand seals, and then make hand seals one step ahead, releasing the ninjutsu the enemy wanted to release.
In terms of practicality, it was actually inferior to the precognitive technique of the guy Luffy spoke of Katakuri's Observation Haki.
Of course, regardless of whether it's the Sharingan's bloodline limit, or Katakuri's unbelievably powerful Observation Haki,
it's a common person's ability.
So these matters are just a mention. Expanding one's horizons is enough. It's impossible to spend more effort on this.
"Next is the last type..."
Luffy said this.
But under Naruto's expectant gaze, he suddenly swung his arm. His arm instantly elongated, stretching to who knows where!
...Sasuke had been hiding in the shadows, secretly observing Luffy and Naruto's training.
He didn't want Naruto, this problematic kid, to steal his thunder.
Sasuke, hidden in the shadows, felt the longer he listened, the stronger this power system Luffy described seemed.
If he could also learn these skills, then next time he might be able to gain an advantage when facing that guy, Uchiha Itachi, wouldn't he?
Unconsciously, Uchiha Sasuke moved closer to the place where Luffy was teaching Haki abilities.
"Oh no!" As Sasuke sensed something was wrong, Luffy's extended arm was already close, grabbing his collar!
Whoa—!
Sasuke was directly pulled back by Luffy's extended arm and fell to the ground.
"You little rascal, if you want to learn too, why are you hiding on the side? What can you hear there?" Luffy frowned and scolded.
"Sasuke!" Naruto cried out in surprise.
"How did you know I was here...? No, how did you get here?!"
"Hmph!" Sasuke slapped the dust off his body and stood up. "Who's sneaking around?"
Although he said this, he had no intention of denying it.
"Hahahaha..." Luffy laughed, "How much did you just hear? Where did I get to in my explanation?"
Sasuke pouted, but still honestly answered the question.
"You've already mentioned Armament Haki and Observation Haki... Now there's only one last type of Haki left to introduce."
"Exactly!" Luffy lightly clapped his hands.
"One sheep is leading, two sheep are also leading. From now on, you'll also sit together and listen to the lecture!"
For some reason, Luffy suddenly felt like he was a good teacher.
Since he was a good teacher, he had to do his duty.
"...As for this last type of Haki..." Luffy looked at the two little ones in front of him, his eyes slightly narrowed!
Whoosh—!
A power imperceptible to the naked eye, not chakra at all, and completely incomprehensible, instantly enveloped Naruto and Sasuke's bodies! Both children were even directly sent flying!
"Boom—!" Both fell to the ground, each closing their eyes and losing consciousness!
"Smack smack..." After several slaps to their ears, five or six times, both finally woke up.
"Ugh... what, what happened?!"
Sasuke stared blankly at Luffy, then looked at the spot where he had just been standing and where he was now lying. His mind was full of questions, and he couldn't remember anything that had just happened.
"Hmph—!" Naruto also came to.
"Who... I feel like someone slapped me a few times... It hurts so much..." He was even more confused.
"This is the third type of Haki." Luffy stood up.
"Conqueror's Haki!"
"Only those with talent, those born with the qualifications of a king, can master this power. Among hundreds, even thousands, of people, there might not even be one person who possesses this talent."
Saying this, Luffy looked at the two wide-eyed boys.
"Your main focus should still be on cultivating Armament Haki and Observation Haki."
