Sasuke would never make a mistake with the Rasengan technique.

The only advanced ninjutsu that Uzumaki Naruto relies on to show off in front of him.

The extreme change of chakra form may be a little difficult to integrate into the change of nature, but even like this, the attack power is already quite good, and the stabbing ability is slightly stronger than Chidori.

Many years have passed since the Fourth Hokage, Jiraiya is traveling abroad, and no one has seen the Rasengan for a long time. Only recently did Uzumaki Naruto seem to be able to use this move. However, in the fierce battle, how many people could see clearly what just happened? Most people just watched the excitement, and the few ninjas who knew a little bit looked at Hatake Kakashi, thinking that it was the student of the Fourth Hokage who taught this dangerous technique to Sakura.

Only Kakashi glanced thoughtfully in Mizuki's direction.

"Do you want to take the blame for him?"

Kakashi shook his head in embarrassment and sighed helplessly.

The Rasengan technique was not a top secret, and there were more than one or two people who knew its principle, and there were also people who were capable of practicing it, and Mizuki was not the only one who had learned it privately. However, no one had exposed it so openly and spread it around.

There is no such thing as copyright in the ninja world. If you can learn other people's ninjutsu, that's your ability. However, randomly spreading some ninjutsu with special meanings is not a trivial matter. This involves some traditional taboos in the ninja world.

Apart from some basic ninjutsu, ninjas rarely pass on special ninjutsu to unrelated outsiders. There are still some taboos in family inheritance and master-apprentice inheritance.

There will definitely be no explicit bans, but customary rules still exist. This is a completely different moral view from that held by Shuimu.

To put it bluntly, Mizuki's Rasengan was stolen and is not worthy of being used on the stage. It's fine to use it yourself, but you can't treat it as your own private property and pass it on to others. If it's an enemy, it may become the root of the feud between the two schools. If irrelevant people spread it at will, some conservative sources will even issue a kill order.

As for Mizuki and the Rasengan, it is not that troublesome, but special attention must be paid to the selection of the professor, otherwise it will cause dissatisfaction among people related to the Fourth Hokage.

"You are such an unscrupulous guy, you treat the unspoken rules of the ninja world as stones on the roadside and kick them away just because you don't like them?"

But then again, Haruno Sakura is also Kakashi's student, so this person is not a bad choice...

Kakashi, who was enduring many stares, ultimately did not say much and just watched the game below in silence.

And our instigator, Lord Shuimu, acted as if nothing had happened and didn't care at all.

How difficult is it to learn the Rasengan? Mizuki doesn't think it's difficult, the only problem is that it's hard to research advanced ninjutsu like the Rasenshuriken. But the attack power of the Rasengan itself is not bad, and it can be considered a very useful A-level ninjutsu.

There is just one bad thing. Like Chidori, it consumes a lot of chakra, so it is difficult to use it as a regular ninjutsu like Uzumaki Naruto.

Originally, Sakura Haruno's chakra amount and compatibility with the Rasengan were very poor, but with the Breath Containment Technique and her excellent chakra control ability, she learned the Rasengan much faster than even the protagonist Naruto.

As for whether Sakura is willing to add chakra property changes and invent her own S-level escape technique in the future, it depends on her own luck.

However, in Mizuki's opinion, Sakura probably still prefers bare-handed fighting, and is not optimistic about her development in the Five Elements Escape Technique.

At this point in the battle, both men have already used most of their strength, but the opportunity to determine the winner has not yet arrived.

Sasuke gave up the naive idea that he could defeat his opponent with just one fatal blow. Instead, he began to face up to Sakura's strength and patiently looked for loopholes in her defense.

He pulled out a Fuma Shuriken from his ninja tool bag, and after closing the blade, he swung it in his hand and used it as a machete temporarily. At the same time, Chidori's lightning flowed along his right hand holding the knife to the blade, and arcs of electricity flashed continuously between the blades.

"The Chidori Blade combined with the ninja tools, these little tricks really haven't been missed!"

At the level of A-level Lightning Release, Sasuke's Chidori has almost reached the limit of what he can master. If he wants to improve it further, it is no longer something that can be achieved through simple practice.

With the Chidori Blade's blessing, it was too easy for the sharp blade to cut through the earth-attributed chakra shield. The chakra shield, which originally had some defensive capabilities, was like paper and could not withstand a single blow.

"Is the defense I relied on no longer effective?"

Sakura's expression froze, and she immediately understood her predicament.

Earth Style - Although the effectiveness of the earth spear has been compromised, it is still a powerful means of attack. The problem is that the earth attribute chakra shield that it relies on for defense has lost most of its effect. The ordinary chakra shield cannot defend against the slashing of a sharp blade for the time being. If you really have to fight head-on, you will suffer a great disadvantage. No matter how much chakra you have, it will not be enough to waste.

Not only that, Sakura is not the only one who can use the Shadow Clone Technique. Sasuke's training during this period depends entirely on this technique.

Seeing Sasuke forming the Ren Seal with his hands, an identical Sasuke attacked with a knife, restricting Sakura's range of movement more and more.

It's not that Sasuke doesn't want to use more shadow clones. After two battles, he can no longer squander chakra. Without Professor Mizuki's tips on controlling the amount of shadow clones' chakra, using human wave tactics would be an unwise act of using one's shorthand to defeat one's longhand.

The two lightning blades wreaked havoc, showing Sasuke's strength to the fullest. Sakura was completely at a disadvantage. If she hadn't had rich experience in sparring with Sasuke and was very familiar with his fighting style, she would have been defeated under Sasuke's momentum.

Although he has the upper hand, Sasuke still needs to think of more ways if he wants to quickly defeat the resilient Sakura.

"Thunder Tiger Kill!"

The Chidori form-transformation attack appeared again, and Sasuke's lightning transformed into the form of a fierce dog with sharp claws and fangs, rushing straight towards Sakura's body.

The power of Thunder Tiger's Killing Blast may not be that strong, but it is very flexible. It dodged the shadow clones that were gathering to intercept it by dodging left and right, and bit Sakura's shoulder in mid-air.

A light blue chakra shield was erected to block Sakura. The Thunder Dog was blocked and dissipated, turning into strands of electric current that dissipated into the air.

With Sakura's strength, the ordinary chakra shield could not block Sasuke's slash, but the defensive effect against energy forms was so-so. Doss's sonic attack was ineffective under this move!
