Naruto: My mother, Haruno Sakura, is so smart that she is almost a demon

In the real world, Uchiha Itachi, who had just reached a deal with his substitute Sakura in Tsukuyomi, looked very tired.

Tsukuyomi would not only aggravate Uchiha Itachi's blood disease; mentally, using Tsukuyomi three times in a row was equivalent to staying awake for nine consecutive days.

The double trauma of mind and body made Itachi overwhelmed, and he had already decided to quit.

Originally, he wanted to reveal that the purpose of his trip was the legacy of the fourth generation, so that Konoha would be on guard against the Akatsuki organization, but after learning about Haruno Sakura's vigilance against the Akatsuki organization, there was no need to do so.

And Sakura saw Uchiha Itachi's complicated look at her, and she probably knew what her mental substitute should have said to him in the world of Tsukuyomi.

After all, the spiritual substitute is the past Sakura. According to her own personality, Sakura thinks that she probably used Sasuke to threaten Uchiha Itachi. The target is most likely the tailed beast, or at least the bankrupt tailed beast like Sora.

"Fire Style: Great Fire Extinguishment!"

Uchiha Itachi, who decided to retreat, made a tiger seal with his left hand and placed it at his mouth, and a ball of blazing flames surged out.

This ball of flame spread rapidly like a locust passing through, sweeping in a yellow momentum, covering the entire river surface.

Although Great Fire Extinguishment is only a B-level ninjutsu, its power depends on the quality and quantity of the fire attribute chakra output by the user.

With the support of Uchiha Itachi's pure and huge chakra, the power of this ninjutsu far exceeds that of ordinary B-level ninjutsu, and can even be compared with higher-level fire style ninjutsu.

"Water Style: Water Array Wall!"

Kakashi did not dare to be negligent, and immediately formed a seal to perform the water style ninjutsu he was good at. Four rotating hemispherical water walls rose from the ground, like four solid city walls.

One of the water walls enclosed Asuma and Hong, another protected Sakura and Sasuke in the middle, the third protected Kai, and the fourth protected Kakashi himself.

"Raikiri!" Kakashi shouted. He knew that Uchiha Itachi was trying to escape with the steam created by the fire escape, so he decisively performed Raikiri before the water array wall dissipated.

In an instant, a white-haired figure holding a blue-green lightning flash, Kakashi's figure was like the lightning in his hand, passing through the hemispherical water array wall and the raging flames, and approached Uchiha Itachi.

Uchiha Itachi did not sit still and wait for death. He had already expected that Kakashi might break through his ninjutsu; however, based on his understanding of Kakashi, the only way for Kakashi to break through his ninjutsu was probably the Chidori trick.

Although Kakashi's Chidori is not comparable to Sasuke's, in essence, Chidori is still a close-range assault ninjutsu.

Just as Kakashi's Raikiri was about to hit Uchiha Itachi, two rows of giant orange ribs suddenly appeared, tightly protecting Uchiha Itachi. This skeleton exudes a strong chakra aura, which gives people a very cold feeling, but its outer layer seems to be burning with orange flames. This contradictory feeling of hot and cold is frightening.

"Sizzle——"

Kakashi's Raikiri stopped on the huge skeleton, and Kakashi's Itachi, who was as sharp as iron, was actually blocked by this tricky bone and could not move forward.

"What!"

Kakashi couldn't believe his eyes when he saw that his signature ninjutsu could only leave a few fine cracks on the skeleton.

"Although you also have the Sharingan, you are not from the Uchiha family and can fully exert the power of that eye.

This is a power that only the Uchiha can obtain, known as the power of God - Susanoo."

The three-leaf windmill in Itachi's eyes slowly rotated, and there was a hint of pride in his cold tone.

Kakashi was also frightened by Uchiha Itachi's weird method and subconsciously wanted to retreat.

But how could Itachi let Kakashi do what he wanted? Four water clones jumped out of the water, holding kunai and rushing towards Kakashi from all directions.

Itachi also had a lot of resentment towards Kakashi.

Although he was very happy about Sasuke's growth, it was because Kakashi taught that pink hair that his plan was disrupted.

Although he agreed to the deal with Sakura, it was more appropriate to vent this resentment on her teacher.

Although Kakashi realized that he was surrounded, he was still a step late.

The situation is very critical now. If you want to break through this dilemma, there are only two options.

The first option is to risk getting injured in exchange for

Win and forcibly kill Itachi's body.

But because his students are here, he can't bear the consequences of failure.

So, he can only choose the second method...

"Raikiri Curved String!"

Suddenly, a chakra line as thin as a pencil core grew out of Kakashi's palm flashing with lightning; this bluish-white silk thread exudes a blue-white glittering light, giving people a sharp feeling.

As the bluish-white chakra line quickly swung out a circle, it instantly cut the four water clones surrounding Kakashi horizontally into two sections.

"What is this..."

Uchiha Itachi was surprised to see that the thin chakra line could so easily cut off his carefully arranged water clones, just like cutting tofu, without encountering any obstacles.

He felt that he underestimated Kakashi. After all, he was also a famous genius ninja before him, and it was impossible for him to have not grown at all over the years.

"You are really worthy of you, Kakashi!"

Uchiha Itachi sighed and increased the output of Yin attribute chakra.

Itachi grew an arm on the orange skeleton and grabbed Kakashi.

Kakashi couldn't just sit there and wait for death. He retreated and clenched his palm full of electric light.

In an instant, four curved strings grew out of his hand, and together with the curved string that cut off the shadow clone, they wrapped around Susanoo's arm.

Uchiha Itachi had absolute confidence in Susanoo's defense. He swung Susanoo's arm, and the huge force drove the curved string that occasionally flashed arcs, directly throwing Kakashi away.

"!!"

Just as Uchiha Itachi was about to chase Kakashi in the air, an unexpected scene happened.

The arm of Susanoo that was entangled by five curved strings was actually directly crushed by five thin silk threads, broken into sections and scattered on the ground, turning into chakra and drifting away.

Although it is only a stage, the ultimate ability of the Uchiha clan, known as the power of God, was actually broken by a seemingly ordinary ninjutsu!

"You are right, Itachi, I have a good student!"

There is a hint of pride in Kakashi's words.

The curved string is a ninjutsu developed by Kakashi based on Sakura's research and development notes of [Stretchable Love].

Its principle is also to give the chakra properties outside the body, but Sakura's [Stretchable Love] combines the stickiness of climbing trees and the toughness similar to puppet lines; while the [Curved String] developed by Kakashi focuses on the excellent chakra conductivity of the chakra line.

Although ordinary steel wire can also conduct lightning escape, it only conducts current, not chakra itself, and a lot of heat will be generated during the conduction process, resulting in loss, and excessive use is likely to cause melting;

The curved string not only has almost no loss, but also can maintain the "sharp" characteristics of Chidori.

In addition, the curved string seems to be stationary, but in fact it is not. The curved string controlled by Kakashi is like a chainsaw, always in a rolling state; that is to say, in order to make the curved string also exert the power of Raikiri level, Kakashi used the high-speed rolling of the curved string itself to replace the process of Chidori "stabbing".

Itachi Uchiha's Susanoo was more appropriately "sawed off" or "cut off" than being cut off.
