In an open field near the Red Base.
Naruto stood in front of Itachi and Shisui, beginning to explain the basic concepts of Nen Ability to them.
Originally, Naruto had planned to have Kurapika be the teacher.
But Kurapika refused.
It wasn't that Kurapika didn't want to teach; rather, he wanted to use the act of imparting Nen Ability to others to help Naruto solidify his own understanding of Nen Ability.
"Nen Ability is essentially the ability to manipulate life energy."
"By freely manipulating the life energy emitted from within one's body, one can enhance their own attack power and defense. After learning the basics of Nen Ability, one can develop their own unique Nen Ability based on their personal characteristics."
"Compared to the Chakra and Ninjutsu used by Ninja, Nen Ability has greater potential for development and creativity."
Naruto spoke without pause, explaining everything Kurapika had told him, as well as his own understanding of the differences between Nen and Chakra.
Both Itachi and Shisui were considered geniuses. Listening to Naruto's explanation of Nen Ability, they quickly fell into deep thought.
"Naruto, Chakra is also a form of life energy, isn't it? Is it easier for people with Chakra to awaken Nen?"
After thinking for a while, Itachi asked curiously.
Naruto gave a thumbs up and smiled, saying, "Exactly. Because Chakra is a product of the fusion of body and spirit, Ninja who possess Chakra find it easier to awaken Nen Ability. This is because Ninja already have a very good grasp of their own bodies!"
"If it were ordinary people, they would need to undergo a period of training to awaken Nen Ability!"
"If that's the case, it seems we should have the children at the base start practicing Taijutsu early."
"Even children without Ninja aptitude need physical training."
Itachi stroked his chin, having already planned out the future development of the base.
"Alright, let's talk about the planning issues after you've awakened Nen!"
Immediately, Naruto began to explain how to awaken Nen.
"Currently, there are two ways to awaken Nen. The first is through training, then sensing the Qi Sensation within your body. As long as you have Qi Sensation, you can mobilize your life energy on your own. Successfully controlling this life energy is what Nen is!"
"Compared to the first method, the second method is more dangerous. That is for me to use 'Hatsu' to stimulate the life energy within you."
"This method of forcefully activating life energy is like installing a faucet on your body that sprays life energy outwards. To turn off the faucet, you can only rely on yourselves. If you fail, it means death!"
"Huh?" Just as Naruto finished speaking, Shisui raised his hand. "Naruto, why do I feel like the two methods you described are the same?"
"Both involve releasing life energy from within the body and then controlling it."
"Hehehe," Naruto chuckled, saying, "The life energy released in the first method can be stopped midway. Even if you can't control the life energy to form 'Ten' on your body, you can still retract the life energy."
"But the second method is an all-or-nothing gamble. Either you learn 'Ten' in a short amount of time, or... you die!"
"Alright, choose! Is it the first method or the second?"
Naruto asked, looking at the two who were deep in thought.
"I want to try the first method first!"
Itachi considered it for a moment and said.
It wasn't that Itachi was afraid of death and dared not choose the second method. Rather, in Itachi's view, only power cultivated and successfully controlled by oneself could unleash its true strength.
Seeing Itachi choose the first method, Shisui smiled and said, "Then I'll choose the first method as well."
"Since you've chosen the first method, then you won't be able to master Nen in a short amount of time!"
"Understood!" He nodded, not changing his previous decision.
"Naruto, can you use Nen to let us feel it?"
Although they didn't choose the second awakening method, Itachi and Shisui still wanted to experience what Nen truly was. This would help them sense the Qi Sensation more quickly.
"Oh," hearing Itachi say he wanted to experience it, Naruto suddenly showed a strange smile and then said, "Of course!"
As he spoke, Naruto snapped his fingers, and a surge of Nen flowed from his body, quickly forming a clone.
That's right, the one Naruto summoned was his Nen Beast, the Five Finger Floral Explorer.
"This is my Nen Beast, the Five Finger Floral Explorer."
Hearing the name Five Finger Floral Explorer, both Itachi and Shisui felt a chill down their spines.
Naruto, not noticing anything unusual about the two, secretly used Zetsu, and then the Five Finger Floral Explorer vanished before Shisui and Itachi's eyes.
After using Zetsu, Naruto continued to explain, "This is just one of the basic abilities of Nen Ability, 'Zetsu.' As long as you use Zetsu to suppress your aura, the Nen Ability you use will not be visible to the naked eye."
Hearing Naruto's words, both Shisui and Itachi instinctively activated their Sharingan, wanting to see if the Sharingan could perceive the Five Finger Floral Explorer in the Zetsu state.
But to their shock, even with their Three Tomoe activated, they couldn't see the Five Finger Floral Explorer.
Their battle instincts told them that the Five Finger Floral Explorer, which had sent a chill down their spines, was still standing there, but they just couldn't see it.
Then they both activated their Mangekyo, and only then could they faintly see the shadow of the Five Finger Floral Explorer.
"How impressive! This ability to remain undetected alone is much more troublesome than Ninjutsu!"
Indeed, in Itachi's opinion, it was troublesome, not unsolvable.
Even if he couldn't see it, Itachi could control his Chakra to spread outwards like threads, which should allow him to sense the Five Finger Floral Explorer before it got close to him.
"Alright, stop wasting your ocular power staring at my Five Finger Floral Explorer! Next, I'll let you experience the true 'Nen.'"
Upon hearing this, Shisui was the first to deactivate his Mangekyo.
Itachi, however, did not immediately deactivate his Mangekyo, still using it to stare at the Five Finger Floral Explorer.
Naruto saw that Itachi was a bit difficult to fool, so he reluctantly shifted his gaze to the more easily fooled Shisui.
"Shisui, are you ready?"
Shisui, hearing this, said with a solemn expression, "I'm ready!"
"Good! Then let's begin!"
As he spoke, Naruto's thoughts moved, and the Five Finger Floral Explorer also began to move.
Under the enhancement of Naruto's Enhancement type Nen Ability, the Five Finger Floral Explorer's speed was very fast. In the blink of an eye, it arrived behind Shisui, and then a nameless finger Thousand Years of Death directly poked Shisui's backside.
At the same time, Naruto pulled out a camera from who knows where and captured the entire scene.
Uchiha Itachi: ...
Itachi, who witnessed everything, felt quite speechless.
