The Fourth Hokage, who had mastered the Rasengan long ago, never incorporated the nature change into it until his death. The same was true for Hatake Kakashi, who never used the Rasengan and only became famous after developing the Chidori, but failed at the crucial last step.

Looking at Uchiha Sasuke's appearance below, you can see how unreliable the Chidori Style is at this stage. The defense and power are still good, and it has gotten rid of the restrictions of Mizuki, but the huge electric sparks have also burned him and left him scarred. The charred blood on his face has not completely dried up, and under his ragged clothes, it is unknown how badly he has been injured. If this technique can be used in actual combat, it is really nonsense. It is really rare to reach this point in a short period of time.

"Chidori is more inclined towards lightning-type nature changes. It is much more difficult to go further in form change. Kakashi, you have to admit that your students are doing a good job."

Under the protection of Haruno Sakura's medical ninjutsu, Uchiha Sasuke's almost self-abuse training method barely made decent progress.

Mizuki stood up, patted his butt, and then stretched his arms and legs.

"Since it's not over yet, I'll go down and try it myself to see where his limit is!"

"Sasuke is in such a miserable state. If you use your real body to go over, won't it make him lose confidence?"

Hatake Kakashi said with a wry smile.

Mizuki shook his head: "I don't agree with you on this point. If Sasuke knew that I beat him up without even showing my true form, wouldn't it be a bigger blow? Isn't it your request to let him experience other ways of fighting?"

After saying that, Shuimu disappeared from the spot with a flash of a teleportation technique.

During the intervals in the battle, Sasuke kept gasping for breath, enduring the pain in his body, forcing himself to stretch, waiting for Mizuki's next attack.

Suddenly, the ground around Sasuke became blurred, and dozens of figures slowly rose from the ground, forming a circle to surround Sasuke again. Then they raised their hands and shot intertwined kunai at Sasuke again.

"Is this an illusion? No, there is something real inside..."

Sasuke, who kept using the kunai in his hand to block attacks, found that most of the kunai turned into phantoms and passed through his body, but occasionally there was a crisp sound of iron colliding. He also snatched a flying kunai in the swift attack, weighed its weight, and confirmed that this was indeed the most annoying type of illusion that mixed reality and illusion.

It was no longer realistic to attack rashly, as he had just suffered a great loss. However, just sitting there and waiting to die was not an option. Anxiously, Sasuke gathered his chakra in his eyes, and the magatama in his pupils spun rapidly, trying to break through the grip of the illusion.

"Can't the Sharingan be cracked? That's really a pity." Mizuki's unpleasant voice once again reached Sasuke's ears.

"You can detect illusions, but you can't get rid of them. Your illusion ability needs to be improved. The Sharingan is a very good bloodline limit, but it is not omnipotent. A butcher holding a divine sword can only use it as a butcher knife. Only a swordsman can unleash its true power. You seem to rely too much on your talent and neglect the comprehensive development of the basics."

"You say so many useless words, Mr. Mizuki." Uchiha Sasuke wiped the sweat mixed with blood between his eyebrows to avoid affecting his vision. "Could it be that this kind of words that hurt people are also part of your attack?"

As Sasuke spoke, he quickly formed hand seals, then opened his mouth wide and flames spread out in all directions. In the blink of an eye, the surrounding land was covered in flames, and in the heat wave, the shadow clones mixed in the illusion were all destroyed.

"Phoenix Fire Technique!"

Shuimu looked at the fires burning around him, frowned, and showed a puzzled look.

"How could it be so unwise to consume so much chakra just to clear the physical attack from the illusion?"

At this moment, a large number of shurikens suddenly appeared among the flying sparks!

"Is this the Shuriken technique? It's a simple idea, but you guessed it right this time."

The trajectory of the spinning shuriken was very erratic, and each shuriken was connected and controlled by a transparent thread. This was similar to the method Mizuki used to trick Deidara.

Sure enough, when Mizuki was stunned, the transparent silk thread closest to Mizuki touched Mizuki's body. In an instant, the shuriken with the silk thread rotated around Mizuki and bound Mizuki. Then, a burst of crisp bird calls sounded, and a figure rushed out of the flame wall. It was Sasuke holding a Chidori, and there was even a small burning flame on the corner of his clothes.

"You have good awareness. If you don't use your full strength, you really can't hurt me..."

A swift figure flashed by, and Chidori landed next to Mizuki in the blink of an eye. A burst of dazzling electric sparks rose up, and then returned to calm.

Uchiha Sasuke looked at Mizuki who was unharmed in surprise and asked: "How is this possible?"

"Surprised?" Mizuki smiled. "The blood limit is not enough to rely on. One or two advanced ninjutsu can't change anything. No matter how good the weapon is, it needs enough basic ability to support it."

Chidori's piercing ability is very strong. With Mizuki's normal chakra shield, it is really impossible to guarantee that it can be blocked. If you really resist it, you may get hurt. But you don't have to resist it to avoid the attack. Chidori's stab has a very high speed, so that Mizuki can't react. But at high speed, a little disturbance may cause a deviation in direction. As long as the distance and angle of the chakra shield are adjusted, Chidori will not be able to use any force when hitting, and finally be led off the track. This operation is not very troublesome for Mizuki, and it is not too difficult to change the appearance of the chakra shield.

Mizuki's body shrank suddenly, and he used a substitution technique, and instantly turned into a piece of wood tied with transparent silk threads. Then he appeared behind Sasuke and grabbed his hand, which was still flashing with electric sparks.

"Are you paralyzed? Your movements are much slower."

He had already consumed a lot of energy in the previous battle. He had to forcefully use the Chidori Style which was beyond his physical limitations, and finally used a large-scale Fire Release Technique. If he were to use another Chidori again, it would take more than a day or two to heal these injuries.

Mizuki pressed down on Sasuke's abdomen and circulated his chakra slightly. The chakra that was about to circulate again in Sasuke's body suddenly stopped.

"Okay, let's stop here for once. Do you really want to fight me to the death?"

He supported Sasuke's shoulders to prevent him from falling down. Then, the healing waves of the Palm Immortal Technique soothed the injuries on Sasuke's body.

"Overall, it's a good job, much better than I thought!"
