"To put it simply, the change in nature is to make better use of the chakra and increase the power of the chakra."

"Hmm." Naruto nodded in agreement.

Asma continued: "The key is how to effectively carry out the change of nature. ”

Yes, that's the point.

Then, this lecture, it was just over an hour, and Naruto was full of gains.

It also confirmed one thing he had guessed in his heart - in the original book, when Naruto was cultivating the Wind Escape Spiral Shuriken, he went to consult Asma. At that time, Asma showed him the chakra knife, saying that he wanted to imagine the attached wind attribute chakra, the thinner it was, the more powerful it was.

In the real world, it's definitely not that simple. Otherwise, the world will be the best player.

Asma said so much, but the most important point was that Naruto's spiritual energy at this stage was not enough to make an efficient change in nature. He had to improve his spiritual energy first, and the cultivation of spiritual energy was a long-term thing.

Still, Asma's lectures are quite important. Naruto took notes. He also knew one thing, the reason why Asma patiently spoke so carefully was probably to thank himself and Jiraiya for finding Tsunade back, so that his father would no longer be tired.

After lunch, Naruto said goodbye to the three generations of them.

He found that the relationship between father and son did not seem to be as stiff as in the comics. Perhaps, after the retirement of three generations, both of them have opened their hearts and talked for a long time, right? In short, everything is going in a good direction. That's pretty good.

Now Naruto has also found a direction for his cultivation, which is to strive to improve his spiritual energy. As for the training method of spiritual energy, Shiori and Asma have given a lot of suggestions. However, those are the usual training methods. Naruto always felt that his efficiency was a little inefficient.

And the fast charge given by the system to add mental energy once is too conservative.

"Is there any way to effectively increase spiritual energy?" He couldn't help but sigh.

Suddenly, a familiar voice answered him. "Perhaps, you can try practicing illusions."

The voice...... Naruto's back suddenly tingled. He immediately turned on the weakened version of the Immortal Mode.

"Itachi?"

As several crows swirled, a figure with only the upper body floating in mid-air. "It seems that you've been through adventures lately and have gotten stronger."

"Doppelganger?" He looked at the man in front of him who had been deified by netizens. Of course, it doesn't matter if that man is a true god or not, but for Naruto now, he is an incomparably formidable enemy.

"Take it easy, I won't attack your spiritual world."

"Huh. You can't afford to mess with the guests in my spiritual world, can you? Having said that, Naruto carefully observed his surroundings while sensing the movements of the chakra in his head, keeping an eye out for Itachi's illusions.

"You're a special person. I'm not here to arrest you today, though. ”

Naruto didn't care, there is a flying thunder god, can you catch it?

Itachi continued, "You've been planning to practice illusions lately, right?" ”

"You're spying on me?" Naruto was secretly frightened, with Brother Ji here, Itachi can also spy on me? But then he figured it out.

Brother Ji is just a clone with no combat power, and Itachi has a way to carry out covert surveillance.

"I can help you, but you have to promise me one condition."

"Do you have such good intentions? I don't believe that a person who slaughters the tribe would have such good intentions. ”

This time, Itachi was silent.

Naruto didn't dare to look him in the eye and could only judge the other person's emotions by the other person's body language. However, the current Itachi is just a black floating spirit, and there is no way to judge his emotions and other information through his body.

"Don't tempt me, just understand that this trade is useful to you."

Naruto didn't immediately agree, he asked, "Tell me first, what do you want me to do?" ”

"If Sasuke doesn't find the stele, you go and help him find it. And remind him that only by witnessing or killing his best friend can he open his eyes like me. Only by opening the Kaleidoscope Writing Wheel Eye can you defeat me. ”

Naruto suddenly frowned, "Why don't you say it yourself?" ”

"You don't need to know." After a pause, Itachi continued, "I've heard that you got a writing wheel from Danzang some time ago. If I share my experience with you, you should be able to master the art of darkness in no time with this eye, right? ”

The conditions are indeed very tempting, as the only remaining illusion, Itachi, his experience sharing is indeed priceless. But......

Naruto felt that this was too much beyond the setting of the original book. How could Itachi say these words in person? Moreover, the previous question is still unanswered-is the weasel of this world, is it a good weasel or a bad weasel?

And, what is used to define good and bad? More importantly, if I do what he says, what will happen is unknown.

Don't think it's just a few simple words, if I told Sasuke, it would definitely have a different effect. What will Sasuke think of me? What is his hidden personality like? What effect did these words have on him? What will he do?

What if I accidentally fall into the "bad" Weasel path?

Naruto, who has been through a lot of things, will naturally be quite cautious.

"I'm sorry, I'm not interested. Good bye! With that, Naruto directly teleported away with the Flying Thunder God.

When he returned home, he first checked his windows, under his bed, cabinets, door frames, etc. In this world set in modern technology, the possibility of a monitor cannot be ruled out.

However, Naruto searched the entire house and found nothing suspicious, which proved that Itachi was using a ninja method to spy on him.

At this time, Brother Ji asked, "What are you looking for?" ”

"Brother Ji, I'm afraid I'm being watched."

"Surveillance?"

"Hmm."

"Speaking of which...... Brother Ji seemed to remember something, "When you went to bed last night, it seemed that a consciousness entered your room." He didn't have obvious ill intentions, so I didn't notice you. ”

Naruto was taken aback, "Yes! That's it! ”

"Enemies?"

"I'm not so sure. But no one wants to be watched, right? Brother Ji, next time, if he comes again, remember to inform me. ”

"Okay. However, you have to understand that the old man has no combat effectiveness. ”

"Hmm." Naruto nodded. I didn't expect Brother Ji's perception to be so keen.

After that, Naruto began to learn the Chicken Brother's version of the Dark Trick. This time, he pondered the notes carefully, and kept asking Brother Ji. It was close to six o'clock in the afternoon that he understood clearly. But that's also just theoretical. It's another thing to actually put it into practice.

To practice illusion, you don't need too much space, you can do it at home.

After dinner, Naruto began practicing.

He first activated the Sharingan, then turned on the weakened Immortal Mode, and then tried to break down the chakra into physical and spiritual energy.

He remembered that when he was taking the middle ninja exam before, he had learned low-level illusions from Orochimaru's subordinates. That is the bell illusion.

He followed what he felt at the time, but soon he discovered that the decomposition of the spiritual energy was too inefficient. It's okay to deal with low-level illusions, but the dark art is an S-level ninjutsu. So, he still ended up failing.

And if you use spiritual energy directly, you can't feel it, you have to mix it into chakra first, and then decompose it into spiritual energy. Isn't that redundant? But when I think about it, I vaguely feel that this setting has a certain degree of rationality.

Theoretically, immortal magic can enhance illusions. However, in reality, even the buff brought by the Immortal Chakra is not enough to deal with the S-class forbidden arts.

After that, he tried a variety of methods, and also discussed a lot with Brother Ji. However, Brother Ji doesn't know much about the ninja system, and the help he can provide is very limited. So, in the end, he still ended up failing.

But he didn't give up. Spiritualization and Flying Thunder God were both S-level difficulties, but he still learned them. So, he's confident. It was only a matter of time before he learned the art of darkness.

Time flew by, in the blink of an eye, and the next day arrived again at six o'clock in the afternoon.

"Hey! Brat! Brother Chicken interrupted Naruto's cultivation, "Buy me a popsicle." ”

"Huh?" Naruto looked at Brother Ji suspiciously.

Brother Ji pointed to the commercial on TV and explained: "It's that kind of popsicle, which can be broken in half." ”

"......" Naruto was speechless for a moment, "Wait a minute, Brother Ji." ”

Seeing that Naruto was still immersed in hard work, Brother Ji sighed silently.

"Boy, maybe you go out for a meal, cut your hair, and maybe inspiration will come?"

It was then that Naruto remembered that he had barely eaten since he had eaten in the morning. Speaking of which, I'm a little hungry.

"Okay." Then after a brief tidying up, Naruto went out. "Brother Ji, I'll go out."

"Hmm." Brother Ji nodded silently, very good boy, when he has strong mental power in the future, maybe I can consider passing on some immortal arts to him, real immortal arts.

After dinner, Naruto walked slowly down the road. Under the not-so-bright street lamp, a large swarm of moths swirled.

He took a popsicle and sat down on a bench where no one was around. In his mind, he was still recalling the process of cultivation just now, and this time, he forgot the time. Let the popsicles melt slowly.

The ice water was ticking, but he still didn't have a clue, not even a direction. This time the Dark Technique is different from the Flying Thunder God.

Maybe...... Am I learning this too early?

Suddenly, a whisper came from the wind, interrupting his memories.

Listening carefully, he could hear that it was Kai and Xiao Li's voices. I couldn't make out the conversation, but it was supposed to be coming from a short distance.

He didn't know what his psychology was, so he looked for the voice and walked over.

It was a three-story building, like a pavilion or something. There are benches for resting, and there are also street lamps that are not very bright.

At this moment, Kai and Xiao Li are silent, but their hearts should not be silent, right? It is also like a flying moth under a street lamp.

Naruto remembered, this should be the life and death choice faced by Xiao Li in the original book, right? Either undergo Tsunade's death-risk surgery, or stop being a ninja for the rest of your life.

If you don't have God's perspective, who's to say it's not a dilemma? At this time, Xiao Li should be at war with heaven and man in his heart, right?

However, Naruto was going to leave there, because even if he knew the ending of the original book. But he also can't guarantee that the world will not change its outcome. It's a matter of life and death, let him choose for himself. It was a choice he had to face.

However, just as Naruto was about to leave, he was almost taken aback by Kai's sudden outburst.

"Lee! Let's choose surgery! ”

"......" I have to say that Mr. Kai is still full of energy. Luckily, there aren't many pedestrians here.
