Konoha: Naruto Taught By Aizen

In the days that followed, Kakashi sank into a corner where inspiration dried up.

Even though he is known as the copy ninja Kakashi, there are moments when he is exhausted.

Under the pressure of Naruto, he continued to teach the known wind ninjutsu.

Some ninjutsu are tasteless, and some are extremely powerful.

Regardless of any ninjutsu, Naruto can learn it in a very short time.

Although the proficiency and stability will be relatively weak, these can be compensated by subsequent practice.

Finally, under Naruto's questioning again, Kakashi's mouth under the mask twitched slightly, and the dead fish's eyes filled with helplessness: "There is another ninjutsu suitable for you, do you want to learn it?"

"Learn, why not learn? What ninjutsu?"

"Thousand Years of Death."

After that, Naruto never asked Kakashi to learn ninjutsu again.

Kakashi regrets that.

Imagine, even with a gentle smile, Naruto first used Kyōka Suigetsu to control the enemy's vision, then used Shunpo to come behind the enemy, and then used Thousand Years of Death to enter the enemy's warmest and most vulnerable parts after a complex knot.

This is the ultimate ninjutsu tailor-made for his bloodline limit.

pity.

He couldn't see this scene.

......

inside the training ground.

At Naruto's request, Sasuke prepares to open Sharingan to crack Kyōka Suigetsu.

"I'm sorry to trouble you this time, Sasuke." Naruto still had his trademark gentle smile.

The opposite Sasuke looked stinky: "Hmph, come on, in front of my eyes, all illusions are nothing."

Sharingan, has a strong resistance to illusion, so Sasuke is confident that Naruto's bloodline limit will be useless in front of him.

"Then, be careful. Shatter, Kyōka Suigetsu." The Kyōka Suigetsu in Naruto's hands fell to the ground, shattered into pieces, and disappeared from sight.

Sasuke only felt a flower before his eyes, and the world seemed to have ripples.

"This is the Kyōka Suigetsu that I hit earlier." Sasuke took a deep breath, he was not in a hurry to turn on Sharingan, and first felt Naruto's illusion with his normal eyes.

"Using the refraction of natural elements such as water, fog, and light to control the other's vision, resulting in a visual deviation." Sasuke remembers Kyōka Suigetsu's abilities and is always on guard.

"This way." Naruto punched Sasuke in the face.

The fist wind burst, Sasuke's eyes widened: "It's right in front of me!" He waved his fist, but he felt lonely, his right shoulder hurt, and he was immediately knocked back a few steps.

However, Naruto pulled back at the crucial moment, but it didn't bring much pain to Sasuke.

"Impossible!!! Even if the vision is deviated, the boxing style is really coming?" Sasuke asked with a puzzled face.

"Illusions are not as simple as you think." Naruto walked up to Sasuke and waved his hand in front of him.

The breeze was blowing, and ripples appeared in front of his eyes. In Sasuke's sight, Naruto's palm fell directly toward his face, and he subconsciously took a step back.

"The human brain is amazing." Naruto put away his hand and explained with a smile: "From your point of view, my blood limit is an illusion of pseudo-illusion, and it creates visual illusions by changing the surrounding environment. The effect, to a certain extent, is not actually an illusion."

Sasuke nodded: "True illusion should be able to affect all senses."

"Wrong." Naruto shook his head.

"Wrong? Could it be that Kyōka Suigetsu can still affect other senses?" Sasuke looked suspicious. "That's one of your misunderstandings." Naruto continued:

"Illusions come from two possibilities. One is the visual system. When there is a blind spot in the visual system, or you are a color-blind person, the information you process is likely to be wrong. The second is that the visual system is correct, but As the brain and other regions outrun the neurovisual system, it reorganizes itself and makes up a whole new correct story."

Naruto's words made Sasuke dizzy.

Although there are some courses in the ninja world that will involve science, they will not be so hardcore.

Those who can settle down and do research are basically very important laboratory members.

Orochimaru, like one of the former Konoha Sannin, used to be a very good researcher.

"In simple terms, in addition to the visual system, there is one of the most important information processors, the frontal lobe. The frontal lobe is a higher-order thinking area, and it is the part of the brain responsible for prediction and decision-making."

"It also means that all visual analysis, computation and prediction in observation happens outside the visual system."

"In other words, the illusion I've woven has been so detailed that it tricked your brain and affected your other senses to a certain extent." Naruto smiled, and under his control, the world in Sasuke's eyes rippled again.

"I can simulate the ripples generated by the punching wind vibrating in the air, and even the detailed changes caused by the surrounding flowers and plants, so that through your eyes, I can construct the scene I want in your mind, which can also affect to a certain extent. Your other senses, is this explanation clear enough?"

"I understand, that's why this blood continuum limit is called the pseudo-illusion art blood continuum limit." Sasuke suddenly realized.

"That's pretty much the truth, so closing my eyes can really restrain my bloodline limit." Naruto nodded: "But most ninjas rely on their eyes."

"Then use Sharingan." Sasuke turned into Sharingan.

With the appearance of Sharingan, Sasuke's self-confidence also began to expand, covering his face and laughing wildly: "I saw it, I saw it again!! I saw the illusion you woven."

"I'm not weaving illusions right now," Naruto said softly.

"Uh..." The air was silent.

"It doesn't matter, use Kyōka Suigetsu, Naruto, I'll beat you with my eyes!" Sasuke laughed wildly.

"As you wish." Naruto waved Kyōka Suigetsu and began to change his surroundings.

Kakashi, who was on the sidelines watching the battle, was also watching all this intently.

Kyōka Suigetsu's real ability is to manipulate the five senses, but it is also easy to manipulate a single vision.

In order to test whether Kyōka Suigetsu's visual manipulation is effective for Sharingan, and to show the details of his abilities to Konoha executives in more detail, Naruto chose to fight Sasuke this time.

When the illusion was completed, Naruto slapped Sasuke lightly.

Sasuke's Sharingan circulated wildly, Chakra gathered at his eyes, and a look of surprise appeared in his eyes.

"I see." Sasuke turned sideways, avoiding Naruto's attack, and punched Naruto in the face with a backhand.

"The Sharingan of 2 Gouyu can decipher visual manipulations that are not fully used." Naruto's heart sank, and he went back and forth with Sasuke a few times.

Sasuke's eyes soon became tired, his breathing was also rapid, and the Chakra in his body was consumed violently.

"Looks like it's the limit." Naruto shoved Sasuke's arms away forcefully and retreated from the battlefield.

"So be it."

"It's not over yet." Sasuke leaned on his knees, gasping for breath, his face unwilling: "I can still fight."

"You've done a great job." Naruto shook his head.

Kyōka Suigetsu's abilities have been known to a certain extent under this experiment.

As long as Naruto uses all Reiatsu, Kyōka Suigetsu is enough to block Sasuke who has 2 Gouyu Sharingan.

You must know that Uchiha's illusion resistance is very high.

As long as Naruto's Reiatsu has a significant boost, Kyōka Suigetsu, who is fully motivated, will be unstoppable by the 3 Gouyu Sharingan.
