Sealing is the highest level of knowledge in the ninja world, compared with sealing, any ninjutsu will fall into disadvantage, even if it is known as the 'Chakra Ancestor', the Great Jian Mu Kaguya, in the end, it was defeated by the sealing technique, therefore, the ninja world's knowledge of sealing has always been strictly guarded.

As the family that is best at sealing, the Uzumaki clan was the first to be wiped out, and even the country of Vortex was destroyed, becoming the first country to be definitively destroyed.

As for the reason......

Naturally, it was to seize the Uzumaki Clan's sealing technique.

"Uzumaki Kukina, she will be sent out on the eve of the destruction of the Vortex Country, and the reason for this is probably not simple......"

Looking at Jiu Yukina, who was seriously explaining the principle of sealing on the podium, Uchiha did not continue to delve further, his current strength is too weak, and he doesn't even have the strength to shinobi, the top priority is to become strong as soon as possible and strive to survive in this troubled world!

When.

The chalk on the hand falls.

Jiu Xingna looked at the chalk on the ground suspiciously, she just felt that someone was thinking about her, so she dropped the chalk carelessly, put her fingers against her chin and thought about it, but didn't come up with an answer.

Maybe it's a delusion.

Jiu Xingna thought about it, and then turned her head with a smile:

"Take Tujun, get up, now tell me what I just said?"

"Uh... Yes... Well...... I do not know! ”

The corners of her mouth twitched, and Kuyukina looked at Obito with a fearless expression, and forcibly suppressed her anger, I'm not angry, I'm not angry...... Angry to deduct wages, last time I smashed the cup of the three generations and still haven't paid it back......

Forget it, I can't bear it.

While!

The biggest shady curtain in the future ninja world. The owner of the kaleidoscope. Madara Uchiha's successor...... The Uchiha took the soil and fell to the ground again.

“……”×46

Looking at a certain Obitu who was covering his head and crying, the whole class lowered their heads from the heart.

How to say, well, in a way, four generations are really a hero.

"That Uchiha imp over there, stand up and answer the question!"

“？”

With a confused face, knowing that Nohara Rin poked him, Uchiha Tsukasa reacted that Kuyukina was calling himself, looking at Kuyukina's eager expression, Uchiha pondered for a moment, and felt that he did not bring soil to resist the beating, and walked onto the podium from the heart.

"Tell me about the principle of sealing I just mentioned."

"The sealing technique is a special system developed on the basis of Chakra's trajectory again, which has the function of banning opponents, imprisoning Chakra, and completely sealing the ninja's ability......"

"And based on this part of the peculiarity, a ninja who is proficient in sealing art can defeat the strong to some extent......"

Looking at the relaxed Uchiha Division, Kuyukina had a hint of surprise on his face, this Uchiha imp actually wrote it down? I think I was taught by Grandma Mito with a stick for three days before I memorized it.

In fact.

The reason why she picked this part is to screen out children who are qualified to learn sealing, sealing is different from other ninjutsu, in addition to qualifications, more important is curiosity about knowledge, only ninjas who meet these two points can learn sealing.

The reason why Yukina Uzumaki came to be a teacher is because Konoha's sealing ninjas are too scarce, and even among tens of thousands of ninjas, there are only a few hundred sealing ninjas, and most of them can only use the most superficial sealing techniques, which cannot meet Konoha's war needs at all.

And her task this time is to select children who are qualified to learn sealing techniques in the school and train them to become qualified sealing ninjas.

"The theories of sealing are vast, and there are only one ninja who can master them, so sealing ninjas often have unexpected means and are very difficult to deal with."

"I'm done, do you have any other requests from the teacher?"

It's just that Kuyukina was stunned, and the Uchiha had already finished what she had said before, and at the moment she was standing quietly next to Kuyukina, and said calmly with her eyes in her eyes.

"Huh?" The Uchiha Division woke up Kuyukina from her contemplative state, and when she found that the whole class was looking at her, she couldn't help but feel a little embarrassed, and hurriedly said, "Ahem, it's very good, what's your name?" ”

"Tsukasa Uchiha."

After remembering the name of the Uchiha Division, Kuyukina hurriedly asked him to go down, otherwise she would be swept away by her majesty on her first day as a teacher, and she almost couldn't maintain a serious expression.

Back in his seat, after this little episode, Kuyukina continued to explain the principle of the sealing technique, while the Uchiha was thoughtful.

"Sealing...... Is it also a type of ninjutsu? ”

Sealing is based on ninjutsu, and although it has gone beyond the framework of ninjutsu until now, it can still be regarded as a type of ninjutsu.

The essence of ninjutsu is to control the chakra, so as to exert a powerful power, and the sealing technique is beyond the ninjutsu, in terms of controlling the stability of the chakra, it has reached an unprecedented degree, if you rely on the principle of sealing, can you solve the problem of thunder chakra?

Thinking about it from another angle, isn't the sealing technique that is good at stability the nemesis of Lei Dun?

"I see, no wonder Kakashi was able to develop Chidori before the Battle of Kannabi Bridge, it was because of the help of his teacher, Bo Feng Mizumon!"

Spiral Pill and Chidori may be a reference to the structure of Spiral Pill, and the Chidori developed by Kakashi is still within the framework of Spiral Pill and has not recreated a system.

In addition, Kakashi's body obviously can't withstand the erosion of Thunder Chakra, but the development of Chidori requires a stable structure, and in this case, his choice is very obvious.

"Sealing."

The Uchiha looked at Kuyukina with burning eyes, as if he had discovered a huge treasure.

"Since the sealing technique is within the framework of ninjutsu, it can naturally be combined with ninjutsu, and Kakashi's choice is to use the principles of sealing to create a ninjutsu, and the facts have proved that he succeeded!"

"He created a powerful ninjutsu, and that is Thunder Escape. Plover. ”

Suddenly, the problem that had plagued him for several days suddenly disappeared, and he found the scroll about sealing from the drawer, and the first introduction of the opening chapter was:

Sealing is an independent branch of ninjutsu that was born and is closely related to ninjutsu.

The answer was already in front of him, if it weren't for the fact that he hadn't finished the class yet, he couldn't wait to go home immediately to verify the idea, and the principle of the sealing technique would be a ninjutsu? If you don't know the future plot, who would dare to believe it if you say it now?!

And after this incident, he was also more determined to develop in an all-round way, otherwise if he encountered problems again, wouldn't he just stare dryly?

……

Jingle Bell –

The bell for the end of class finally rang, but the Uchiha didn't go home right away, but deliberately waited until the end, waiting for Uzumaki Kushina to follow when he started to leave.

"Teacher, I want to learn sealing."

Straight to the point, Uchiha understands Kuyukina's character, and the more he twists and turns, the more unpleasant it is, so it's better to make it clear from the beginning.

Follow Jiu Yukina to learn sealing, this is not a whim, now his chakra is not enough to support learning powerful ninjutsu, instead of wasting time on refining chakra, it is better to take this opportunity to learn sealing, sealing is biased towards theory, although chakra is also needed, but there are not many requirements for chakra.

It's just right to study at his current age.

"Huh? Why did Si Jun want to learn sealing? ”

Kuyukina stopped, but it wasn't Kuyukina's voice that came, and the Uchiha raised his head and was surprised to find that it was Uchiha Mikoto standing in front of him.
