There was silence in the conference room for a while, and then, Tsunade, continued, "I said before that you can invite Kiri Shinobi to participate in this Konoha middle ninja exam, what do you think?"

"Isn't it too rushed?" said the third Hokage, "If you just rely on the messenger to go back and forth, it is estimated that it will take several months before we can talk about it!"

"So I suggest that the fifth generation of Mizukage come directly to Konoha to meet us. Tsunade smiled slightly, and said meaningfully, "It's just right, I also want to see with my own eyes, the second female 'shadow' in the five ninja villages!"

The fifth-generation Hokage and the fifth-generation Mizukage are the only two female "shadows" since the birth of the ninja village system, whether it is sympathy or-for-tat, Tsunade is full of curiosity about each other.

……

……

When Sakura Haruno came to the ninth training ground, Konohamaru and they had been training there for a long time.

"Teacher, you're late again!" saw her coming, Konohamaru wrinkled his nose and shouted.

"The teacher is lost on the road of life again!" Meng Huang also pouted.

"I told you yesterday," Sakura Haruno said with a smile, "I'm going to have a meeting this morning, so you guys train first!"

Konohamaru pouted: "It's almost noon, how can a meeting be held for so long!"

Speaking of which, the ninja world pursues efficiency, there is not so much red tape, and meetings like to go straight to the point, so it won't be stinky and long. So it's rare to have a morning meeting, and it's normal for Konohamaru to have such suspicions.

"That's true. Sakura made a look of belief or not, "This meeting is special, it's a high-level meeting, only the highest-level Konoha leaders can participate, and there are a lot of things to discuss, that's why it's so late!"

"The teacher is lying to us again!" Meng Huang said with wide eyes, "You have just been promoted to the upper ninja, why can you participate in this kind of meeting!"

Sakura Haruno smirked: "Hehe, that's because I'm very powerful, my strength is a ninja who can rank among the top few in Konoha!"

Habitually blew himself a wave.

Well, that's also true.

Udon suddenly asked, "Then can we also practice like the teacher for two years and be so powerful?"

"Huh?" Sakura Haruno was speechless.

This is a question that seems to be difficult to answer. The three students in the Sakura class in Haruno have very good qualifications, and there are three generations of Hokage who have trained them by themselves, so it should not be a problem to reach the level of elite ninja in the future.

But the elite ninja and shadow level are a threshold......

If you want to cross this threshold and become a 'shadow' level ninja like Sakura Haruno, it is not easy to do it, either you have talent, secret arts, or resources.

Like Sakura Haruno, she has average talent, no secret arts, and ordinary resources - there is one scarce resource - and then she was promoted to the shadow level in two years, which is just a special case......

"Two years...... Sakura laughed dryly, "As long as you work hard to cultivate, you will definitely become very strong!"

It was obvious to the three students that she was perfunctory.

"Ahem," the girl coughed twice, "I saw that you had completed the cultivation task left to you some time ago, so today I will teach you something new according to my promise!"

"Is there really something new?" said Konohamaru and Udon, their eyes lit up.

"Is it your signature ninjutsu Wind Blade Torrent?" Meng Huang tugged at her sleeve excitedly.

"Hehe, the Wind Blade Torrent is not a ninjutsu that you can master...... "Haruno Sakura laughed dryly, "That technique is extremely difficult, in addition to the extremely high chakra control, it also requires the caster to master the nature changes of the deep water attribute and the wind attribute!"

"In terms of difficulty, it's a super S-level ninjutsu that is more difficult than the average S-rank!" she said.

Even if you don't consider the nature change into it, just simply simulating the super water gun technique of the water knife, it is also a very difficult ninjutsu; the second generation Hokage's water breaking wave is almost exactly the same as the super water gun technique, and the difficulty of manipulation is two grades weaker than the water gun technique, which is already an S-level difficulty ninjutsu.

The difficulty and intensity of the wind blade rapids of the Haruno Sakura can be imagined.

This is her signature ninjutsu!

So far, no one has been able to stop this move.

The person who can learn this trick, according to common sense, should be her personal disciple to learn, Meng Huang and the three are actually just her students, not even disciples;

It's just that, not to mention the Wind Blade Torrent, there are not many ninjas in the entire Konoha who have the ability to master the super water gun technique......

There is also a way to learn this trick - she has already entered the ninjutsu into the Konoha database, as an advanced version of the water broken wave, qualified ninjas as long as they apply, they can also see the information of this ninjutsu;

In fact, there are two or three senior water ninjas in the dark department, who have applied for the information of super water gun skills, and are now learning; one of them has been practicing for a year, and can probably achieve the effect of water breaking waves, and the full version of super water gun skills is still far away from him.

"In the past, you always said that I was biased and taught Meng Huang Shui Dun more, but in fact, I was just good at Shui Dun and knew a lot about Shui Dun!" Haruno Sakura stood in the middle of the three and said with a smile, "Anyway, I won't teach Shui Dun today, let's learn an illusion, it's my own sound illusion!"

"Is it for me?" said Udon in surprise.

"Well, that's all it takes, but the two of them can learn it too!" Sakura said, nodding.

Konohamaru has a grandfather who can teach ninjutsu, and she can teach Meng Huang Shui Dun anything he wants to learn, and only Udon is more embarrassing, so Sakura Haruno has to put more thought into him.

However, generally there are ninjutsu that can be learned by three people, and Sakura will not open a small stove for a student alone.

In this way, the three students in Haruno Sakura's class often complained about her partiality.

- A long time ago, in Class 7, she and Naruto had complained about the teacher's partiality and special attention to Sasuke's problems.

When she became the leading teacher herself, she was also complained about partiality by the students, and Sakura found that this problem was really difficult to explain.

For example, Meng Huang in Haruno Sakura's class, she can't help but teach if she wants to learn Water Escape Sakura, right? But Sakura is the best at Water Escape, so Meng Huang also learned the most from her, and Udon and Konohamaru will naturally be a little unbalanced.

Konohamaru is the most uncomfortable, Sakura has hardly taught him ninjutsu, in addition to because she is not familiar with fire escape, but also because Sakura knows that the three generations of Hokage will teach him ninjutsu, and she doesn't need to bother, with her fire escape attainment, it may mislead the students, but in Konohamaru's opinion, the teacher just doesn't care about him, and it seems that Sakura doesn't like him very much.

Sakura Haruno can only fight with him more.

From Sakura's point of view, she wants all three of them to develop in a balanced way, but in the eyes of the children, the teacher sometimes doesn't do it fairly.

It's really hard to make a bowl of water even.

Fortunately, the three students only complained, knowing that their teachers were not unwilling to teach them, and the atmosphere in the Haruno Sakura class had always been very harmonious.

"It's an illusion, but in fact, this technique also has a good attack power," Sakura Haruno continued, "You can adjust it to an offensive ninjutsu and a supporting illusion according to the situation. ”

"It's called 'Phantom Voice'. ”

"I'll explain the principle to you first. ”

In general, sound illusion uses sound as a medium to knock chakra into the enemy's mind.

But the illusion technique developed by Sakura Haruno is, in essence, a ninjutsu that uses sound as a weapon to attack the human body and affect people's psychology and consciousness.

"Have you ever heard of infrasound?" Sakura Haruno asked, holding up her index finger.

She looked at the blank expressions on the faces of the three of them, and then continued: "You should know that sound is a kind of wave, and the sound we can hear is actually a sound wave with a frequency of 20 to 20,000 hertz. Have you ever wondered what happens if the frequency of a sound wave falls below 20 hertz?"

"We're going to not hear you!" replied Udon first, who had the best academic performance of the three, "so it's infrasound!"

"That's right, infrasound is a sound that the human ear can't hear. Sakura Haruno smiled encouragingly at Udon and said, "However, infrasound waves can still affect the human body, and they are very harmful to the human body!"

"There are four frequencies of brain waves, of which alpha waves are the basic rhythm of normal human brain waves when they are awake, and the frequency is constant at 8-12HZ. When the frequency of infrasound waves is close to it, infrasound waves can act on the human brain and cause harm, affecting the mind and consciousness. If the medium of sound illusion is changed from ordinary sound waves to infrasound waves of this frequency, the physical damage caused by infrasound waves to the brain and the mental damage caused by illusion to the brain will be superimposed, and a strong effect will be produced!"

"Sounds amazing!" Udon said with wide eyes, as an illusion ninja, he was the first to react to his sensei.

Sakura Haruno nodded.

"Of course, after listening to this introduction, you should be able to think of the advantages of this ninjutsu, right?"

"Pros?" Udon frowned.

The three of them pondered for a while, and then Udon rolled his eyes and said, "The first is that it is hidden enough! Because we can't hear this sound, it can act on the enemy silently!"

"The second is that the effect is very strong!" Konohamaru also hurriedly raised his hand and hurriedly said, "Because it is a combination of physical damage and mental damage!"

"The third is that it's hard to crack!" Meng Huang interjected not to be outdone, "Because the general method of dissolving illusion can only suspend the mental damage caused by illusion, but it can't remove the physical impact caused by infrasound!"

Bang Bang Bang ~!

Sakura Haruno applauded and said with a smile, "You're all smart!" and had a tacit understanding, even speaking in a style.

"Actually, it has another advantage, which has to do with the nature of infrasound. Sakura continued, "That's because the medium of propagation absorbs low-frequency sound waves poorly, so it's very penetrating and can reach targets far away. Even if a wall of earth tens of meters thick is built with earth, it can penetrate the past, and generally things that can insulate it have little effect on it. ”

However, the real answer Sakura Haruno did not say.

In fact, its biggest advantage is that it doesn't need the Blood Inheritance Limit and the Writing Wheel Eye, nor does it need to master immortal arts and secret arts, and it can be cast...... This is a pure civilian ninjutsu, and it is a very powerful civilian ninjutsu that is comparable to the blood inheritance illusion!

If it weren't for the fact that her combat system had been finalized, maybe Sakura would have really put a lot of energy into it, tapping into its full potential and using it to compete with other illusion masters!

Sakura Haruno put her expression very seriously in the end.

"I must warn you that this is not a simple illusion!"

"Infrasound waves with a frequency of 4 to 18 hertz can resonate strongly with the internal organs of the human body, thus injuring the enemy's internal organs, especially 7 Hz infrasound waves, which can produce fatal damage!" she glanced at the three students, who were all sitting and listening, a little surprised to hear this.

"So, this move can also be used as a purely offensive ninjutsu! But you have to be cautious, especially in battles like sparring, you can't use this move casually, you know?"

"This ninjutsu is very strong. However, it is not difficult to master it, how the usual sound illusion uses chakra to create sound, you have all learned, the same technique can also produce infrasound waves. ”

"However, you must be careful when practicing, this technique is very dangerous, you must pay attention to controlling the release of infrasound waves in front of you, otherwise you will hurt yourself, so I recommend that you try to use shadow clones to learn this ninjutsu!"

"Finally, I would like to remind you that this is the teacher's secret technique. Without my permission, you are not allowed to mention this ninjutsu to anyone else, and it must be kept absolutely secret, you know?"

Because the difficulty is not high, this ninjutsu spreads, and it is a bit troublesome, unlike her Wind Blade Torrent, the super high difficulty of casting it has a strong persuasion effect for ninjas who are interested in learning it.

When Sakura Haruno said this, she saw that the three students had already listened, and nodded again and again, so she stopped preaching.

She puffed up the chakra and began to demonstrate this ninjutsu.

"Pay attention to the order of my seals!"
