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 will not only make Uchiha Itachi's bloodline disease worse; mentally, using Tsukuyomi three times in a row is equivalent to staying awake for nine consecutive days.

The double trauma of mental and physical trauma overwhelmed Itachi, and at this time he had already considered retiring.

He originally wanted to reveal that the purpose of his trip was the Fourth Hokage's legacy, so that Konoha would be on guard against the Akatsuki organization. However, after learning about Haruno Sakura's vigilance against the Akatsuki organization, there was no need to do this.

When Sakura saw the complicated look Uchiha Itachi gave her, she already knew what her spiritual substitute must have said to him in Tsukuyomi's world.

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

"Fire Escape·The Great Fire Extinguishes!"

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

The ball of fire spread rapidly like a swarm of locusts, sweeping across the entire river surface in a yellow color.

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

Supported by 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 Escape·Water Formation Wall!"

Kakashi did not dare to delay and immediately used his water ninjutsu. Four rotating hemispherical water walls rose from the ground, like four solid city walls.

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

"Raikiri!" Kakashi shouted. He knew very well that Uchiha Itachi was trying to escape with the help of the steam created by the Fire Style, so he decisively used Raikiri before the water array wall dissipated.

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

Although Kakashi's Chidori is not comparable to Sasuke's, in essence, Chidori is still a close-range surprise attack 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 powerful chakra aura, giving 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.

"Thorn-"

Kakashi's Raikiri stopped on the huge bone. Even Kakashi, who was as good as Itachi in cutting through iron, was 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 tiny cracks on the skeleton.

“Although you also have the Sharingan, you are not a member of the Uchiha family and can fully utilize the power of that eye.

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

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

Kakashi was also frightened by Uchiha Itachi's strange methods and subconsciously wanted to retreat.

But how could Itachi let Kakashi get his wish? 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, his plans were disrupted because of Kakashi's teaching of the pink-haired boy.

Even though he had agreed to the deal with Sakura, it was only fitting that he vented this anger on her teacher.

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

The situation at this point is already extremely critical. If you want to break through this predicament, there are only two options.

The first option is to risk getting injured in exchange for victory and forcibly kill Itachi's true body.

But with his students here, he couldn't afford to fail.

Therefore, he could only choose the second method...

"Rachel Curved String!"

Suddenly, a chakra thread as thin as a pencil lead grew out of Kakashi's palm, which was flashing with lightning; this bluish-white thread emitted a blue-white glow, giving people a feeling of being extremely sharp.

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

"What's this……"

Uchiha Itachi watched in amazement as the thin chakra thread cut through his carefully arranged water clones so easily, like cutting tofu, without encountering any obstacles.

He felt that he had underestimated Kakashi. After all, he was a talented ninja who had a long-standing reputation before him. It was impossible for him to have not grown at all over the years.

"You are truly worthy of me, Kakashi!"

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

I saw another arm growing out of the orange skeleton and grabbing towards Kakashi.

Kakashi couldn't just sit there and wait for death, so he stepped back while clenching his palms that were full of lightning.

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

Uchiha Itachi had absolute confidence in the defensive power of Susanoo. He controlled the arm of Susanoo and swung it. The huge force drove the curved string that occasionally flashed arcs of electricity, and directly threw Kakashi away.

"!!"

Just as Uchiha Itachi was about to chase Kakashi in the air, something he didn't expect happened.

The arm of Susanoo, which was entangled by five curved strings, was actually shattered by the five thin silk threads, broken into pieces and scattered on the ground, turning into chakra and dissipating.

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

"You're right about that, Itachi. I have a good student!"

There was 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 on [Stretchable Love].

The principle is also to give external chakra properties, but Sakura's [Stretchable Love] combines the stickiness of tree climbing and the toughness similar to puppet strings; while the [Curved String] developed by Kakashi focuses on the chakra string's excellent lightning chakra conductivity.

Although ordinary steel wire can also conduct lightning escape, it only conducts electric current, not chakra itself, and a lot of heat will be generated in the process of conduction, resulting in loss. Excessive use may cause melting.

The curved string not only transmits the chakra of Raikiri with almost no loss, but also maintains the "sharp" characteristic of Chidori.

In addition, the curvature seems to be still, but in fact it is not. The curvature controlled by Kakashi is like a chainsaw, always in a rolling state. In other words, in order to make the curvature also exert the power of Raikiri, Kakashi used the high-speed rolling of the curvature itself to replace the "stabbing" process of Chidori.

It would be more appropriate to say that Uchiha Itachi's Susanoo was "sawed off" or "cut off" rather than being chopped off.
