Konoha, ninja school.

A large classroom was packed, packed with Konoha ninjas with different characteristics, most of them were ninjas from the enchantment class, and the rest were some special ninjas.

"Did you hear that? What kind of formation do we seem to be learning today? ”

"I heard from my wife's best friend who simplified and merged the sealing technique and the enchantment technique."

"Brother, how are your girlfriends? Elaborate! ”

……

"Impossible, absolutely impossible!"

A round head ninja clapped his hands and spoke excitedly, "When I first learned the Sealing Technique, the Mentor only brought me a book called the 'Sealing Technique'. ”

"Sealing? Just one copy? So little? A bangs ninja was surprised.

The head round ninja had tears in his eyes, "That book is just a table of contents!" ”

"Ahh I'm afraid I won't be able to finish it in 20 years. Bangs Ninja exclaimed.

The head round ninja slapped the table and stood up, and swore an oath: "So, even the sealing technique of the four generations of Hokage, everyone doesn't dare to say that they summarize and simplify the sealing technique, this must be a person who sells fame and reputation." ”

A sharp-chin ninja put his finger on his lips, motioned for the round-headed ninja to whisper, and then said softly: "The one who taught us today is the son of the fourth generation of Hokage, the godgrandson of the third generation of Hokage, who knows how to understand!" ”

The head round ninja sat down decadently, "Hehe, a yellow-haired boy knows what sealing techniques are, this is obviously building momentum for his grandson." ”

The more the head round ninja spoke, the more angry he became, "If he really understands the formation, I'll eat this table!" ”

"Nani, I see that you are not only round-headed, but also iron-headed!" Bangs ninja exclaimed quietly.

Suddenly, the door to the classroom opened.

Konoha higher-ups entered the classroom one after another, led by Sarutobi and Danzo, followed by a group of masked ninjas from the shadows and roots. Although nominally the root belongs to the dark department, anyone with a discerning eye knows that it is the private armed forces of Shimura Danzo.

All the ninjas present immediately stood up when they saw this battle, not daring to make a sound.

"Hehe, everyone sit, don't worry about the old man and me." Ape Feiri waved his hand, and then led the group directly to the empty seat at the back of the classroom and sat down.

After all the ninjas in the audience sat down, the atmosphere became gloomy. Even the head round ninja of the head iron is silent, after all, he is just the head iron, and he is not stupid.

At this time, a cheerful voice sounded at the door.

"Good morning, everyone! Except for a certain elder. ”

Everyone in the classroom felt a strange feeling.

This kid is polite, but he doesn't seem to be much.

Tuan Zang glanced at the ape flying sun, as if to say, look at the good grandson you taught.

Ape Feiri smiled bitterly, but secretly said in his heart, don't you know what you did yourself? Don't blame Naruto for hating you. But Naruto's kid too, no matter how annoying he is, he can't show it, this is the Hokage's self-cultivation, and I have to talk about this kid when I go back.

Naruto, who didn't know that he was going back to be trained, jumped up and down directly on the podium, there was no way, if he didn't stand up, the people in the audience were afraid that they wouldn't be able to see him.

Regardless of everyone's strange gazes, Naruto was like a self-cooked oyster, and said directly: "Introduce yourself, my name is ...... Check the sea. ”

"It's the teacher who gave you a formation pattern class, you can call me, Teacher Cha."

There was a commotion among the people in the enchantment class under the field.

What?

It's actually this little kid who teaches us lessons??

Everyone in the enchantment class had this idea in their hearts, but no one dared to say it, because Hokage-sama and the elders were watching from behind, and wouldn't it leave a bad impression if they raised objections at this time.

So, everyone is waiting for a head iron man to take the lead.

Feeling the gaze from all directions, the round head ninja is like sitting on pins and needles, just now I was just talking hi, don't look at me!

Naruto looked at the crowd in the arena, wondering why they were all looking at the round-headed ninja with a sweaty head.

"I know you have a problem with me. But I'm able to stand in this position because of my own ability, not because I have a Hokage father and a Hokage grandfather. ”

Such an astonishing speech made everyone feel speechless for a while, but also speechless for another.

Tuan Zang glanced at the ape flying sun slash again, and saw what you taught...... , you puff up your chest and be proud of your fart.

Sure enough, I shouldn't have let you be the Hokage!

At this moment, the little white dragon on Naruto's body trembled slightly, and everyone in the classroom suddenly felt a pressure on their shoulders. The shoulders of the mid-ninja level sinked suddenly, and only the upper ninja could easily hold on.

As for the dark part and root ninjas in the back, I don't know if it's easy or not, and I can't see it with a mask anyway.

Sarutobi said with a smile, "Naru...... The sea, unleash your ninjutsu. ”

When the ape Feiri's words fell, everyone felt a lightness on their bodies, and they immediately sat up straight, this child was obviously not simple.

After all, the Uchiha Itachi of the Uchiha family used to go to the battlefield to kill people at the age of four, and now a three-year-old child will use this large-scale control ninjutsu, right?

It's not surprising!

How could such a young child release ninjutsu and directly suppress dozens of middle ninjas.

It's just outrageous, the mother opened the door outrageously, and the outrageous arrived home.

"Ahem." Naruto on stage pretended to cough.

"Okay, let's get straight to the point, this time the content of the teaching is called the formation pattern. I've combined the Sealing Technique and the Enchantment Technique into one, fused them, simplified, extracted them, and then turned them into functional modules in a modular way. External interfaces are then provided, and modules with specific functions can be started as long as specific chakras are entered into these interfaces. These modules are called formations, and multiple formations work together to play a function, which is the formation. ”

"The biggest advantage of the pattern is that as long as you know the pattern, then anyone can make it. As long as you understand the interface of the pattern, then anyone can use the pattern and the formation! ”

"From now on, everyone will be a formation mage!" Naruto solemnly announced.

"...... Uproar"

This time, everyone in the field really couldn't help it, and they all started to discuss, even the group that had known the content for a long time was also slightly moved in their hearts, if this was the case, then there would be more ways to play various forbidden spells in the future.

Looking at the little cutie who was fooled in the field, Naruto smiled slightly, the requirements were indeed lowered, but in fact, how can it be so easy, I will change all the bugs in the future!

"Okay, having said that, let's directly demonstrate the function of the formation!"

Naruto pulled out a thin sheet of metal, a brush, and a vial of light blue liquid.

"Does anyone want to come up and try it? I need a classmate with a fire attribute. Naruto looked at the crowd below.

Feeling the gaze from all directions again, the round head ninja burst into tears, you are enough, don't keep staring at a sheep wool.

"Okay, then this classmate, please come up and cooperate with me in the demonstration."

Suddenly, the audience burst into applause.

The head of the ninja came to the stage, Naruto took out a brush, dipped it in a light blue chakra alloy liquid, and then began to draw on the metal sheet.

After a while, one after another, the formation patterns full of mysterious aura appeared on the metal sheet and combined into a larger formation.

"This is a formation that I have formed with a combination of multiple formations, and its function is to convert the input fire attribute chakra into a fire escape fireball technique. This classmate, please enter the fire attribute chakra to try. ”

Naruto handed over the array disk, "This is the interface, enter the chakra into this place." ”

The head round ninja carefully took the array disk, and then slowly entered the chakra into the interface.

In the next second, a fireball with a diameter of one meter quickly emerged from the sky above the array disk, and the blazing fireball emitted an amazing heat wave.

Then Naruto swiped it with one hand, and the fireball disappeared directly into the air, as if nothing had ever happened.

In addition to the round head ninja's face is a little dark, as well as bangs ninja loses bangs......

However, the parties didn't care, because they were in a frenzy now, and their gaze at Naruto turned red.

Usually ninjas want to learn ninjutsu, there are only a few ways, such as making merit in exchange for ninjutsu, leading a team to ninjutsu or teaching by teachers, etc., like this situation of teaching dozens of people at a time, and only the ninja school teaches the three-body technique.

Not to mention the experience summarized by the formation master directly like today, that's right, his round head ninja has already decided that this little ...... on the stage Teacher Cha must be a formation master!

Many ninjas who have learned the sealing technique have mixed feelings in their hearts, and there is a lot of room for the future development of this formation.

In the future, the cost and qualification requirements for ninjas to learn sealing will be greatly reduced. After all, most of the people present had learned the sealing technique, and they all knew about the damn 'Sealing Technique'.

Although they were very happy to see the 'Sealing Encyclopedia' swept into the dust of history, why was it a little unhappy?

In the past, there was a saying circulating in the circle that persuaded people to learn the sealing technique. Because learning the sealing technique consumes a lot of time and energy, very few people end up learning and succeeding, and even if they learn it, they can only be a support staff and watch their teammates carry the whole field. Sometimes you have to take the risk to seal dangerous ninjas, or tailed beasts!

Naruto's blazing gaze in the field made Naruto take it away, and he took out a thick book directly from behind him, which read, 'Formation pattern from entry to earth'.

The round-headed ninja raised his hand tremblingly, "Teacher Cha, this ...... This can't be a directory, right? ”

"Uh, how is it possible, this classmate is thinking too much. This book records the patterns I created, as well as the instructions for using their interfaces, which is the textbook for our class later. Come to this classmate, you can help me distribute the textbook. ”

With that, Naruto pulled out a hill-like textbook from behind him.

The head round ninja was dumbfounded, he was standing on the podium, obviously seeing that Teacher Cha's hand was empty when he was behind him, how could he conjure up a bunch of textbooks when he got to the front!?

It's not scientific!!

At Naruto's signal, the head round ninja began to hand out textbooks.

"First of all, the ugly words are ahead, these textbooks must not be leaked out, otherwise they will be dealt with as a traitor!" Naruto said solemnly.

In his heart, he secretly added that even if it leaked out, it would be fine, and by the way, he would improve the overall level of the ninja world, so as not to see that after the arrival of the big barrel wood clan in the future, oh, it was all 6.

Looking at the crowd who had carefully taken over the textbooks, Naruto planned to talk about the future and expand the students' horizons.

Well, actually, it was just a few minutes before class ended, and he wanted to get over.

"Taking advantage of the time to distribute textbooks, let me talk about the future development of the formation."

Naruto smiled slightly, "In my plan, in the future, I will use a super-large formation to surround the entire Konoha Village. When an enemy invades, a powerful barrier guardian Konoha will be created. There is also a larger range of perceptual formations. Once you spot an enemy, immediately send an elite squad to the battlefield to destroy all invading enemies. ”

"And on the battlefield of the future, it will no longer be a solitary show for powerful ninjas. Our middle ninja and lower ninja can also play an important role, and when the time comes, we will work together to build a large-scale formation, release ultra-long-range and large-range offensive ninjutsu, and directly wash the ground with firepower. ”

"Suppress all disobedience!"

The atmosphere off the field is hot again, ninja is a killing profession after all, there is nothing more attractive than a powerful ninjutsu, if there is, it is a more powerful ninjutsu!

"Good!!"

"Teacher Cha is so good!"

"It's on fire!"

"Ding, ding, ding." The bell rings for the end of class.

Sarutobi gestured to Naruto and hurried out.

What has the old man been doing lately? Weird.

"Thank you, Hokage-sama, for taking the time out of your busy schedule to come over and sit in on the class." Naruto said equally impatiently.

Everyone stood up respectfully and said in a loud voice from the bottom of their hearts, "Congratulations to the teacher." ”

After Sarutobi and the others left, Naruto followed him out of the classroom.

"Teacher Cha, bridge bean sack!"

Naruto looked back and it turned out to be a ninja with a round head, "Is there something wrong with this classmate?" ”

The head circle ninja said respectfully, "Teacher Cha, I have a few questions I can ask you?" ”

"Yes, talk as you go."

"Teacher Cha, what I don't understand is that although the scroll is difficult to manufacture and the output is not high, the effect is similar to that of the array plate. In contrast, array discs are indeed easy to produce, but the materials are much more expensive than reels! ”

The head circle ninja said seriously, "According to my observation, the array plate used for the demonstration is chakra metal, right, this chakra metal array plate is enough to make more than ten ninjutsu scrolls." ”

Naruto looked at the head round ninja in surprise, but he didn't expect to meet a careful one, and he immediately saw the 'drawbacks' of the array plate.

"You're right! Attentively. ”

Naruto, who had played the 'Heart of Love', first gave a wave of affirmation and patiently explained, "The materials for the ninjutsu scroll are expensive, and they are disposable. In terms of production, it can only be made by experienced and powerful ninjas, and it cannot be mass-produced at all, which means that the scroll can only be used on a small scale. ”

After a pause, Naruto continued, "As for the array disk, it is reusable. The most important thing is that it can be produced in large quantities, the operation is simple, and it also has room for upgrading and expansion, such as today's Fire Escape Great Fireball Technique Array, as long as the formation pattern is adjusted, it can be changed to the Fire Escape Hao Fireball Technique, and the power is greatly increased. ”

Naruto smiled intriguingly, "As for the material question you want to ask, let me make sure you really want to know?" ”

The head round ninja thought for a while, then nodded resolutely and replied, "Teacher, I want to know!" ”

"As for what you said about the high cost of chakra metal. Hehe, my institute already has a method for mass production of chakra alloy, and the array disc and the blue chakra alloy liquid demonstrated today are the results of the institute. ”

Naruto glanced at the round ninja, "Why don't you come with me for a visit?" ”

The head round ninja was a spirit at this time, and finally reacted, he seemed to have asked something that should not be asked, how should he answer at this time, so as not to let Mr. Cha think he was a spy!!

Looking at the round head ninja with the cold sweat wetting the vest, Naruto decided not to tease the child, and look at the child.
