When Kosuke finished transcribing the detailed explanation of Konoha Ryu's cultivation on the ninjutsu scroll, he handed it over to Naruto Bokaze.

Naruto Bokaze pointed to the cultivation part of the Unsealed Illusion: "Grandpa Kosuke, since there are physical arts, ninjutsu, and illusions that don't require sealing, is sealing really necessary?" A water dragon bullet technique knot 44 Indo-Pacific troubles. ”

This is also the question of Naruto Bokaze's past and present lives: Is it necessary to seal? In the early stage, various sealing actions, knowing the world is power (still have you time to get the stalk about the original Moe King Mu no Ben Sakura?) ）。

In the later stage, it can be understood that the ninjutsu system collapses with too much B, and a pose can release powerful ninjutsu.

And what about the ancient times? The ninja religion established by the Six Paths Immortal Otsuki Yuroi is an ideological concept, and the pioneer of the ninjutsu seal battle is instead his son Indra, the son of the genius of the heavens, and the ninjutsu seal spread later.

Prior to this, the Six Dao Immortals, Asuras, and other ancients who could use chakra were to condense chakra directly in their hands, and use chakra to control or mimic the power of water, fire, earth, wind and thunder for production and battle.

The strength of the ancients in this world is far from that of the Otsuki family. At the beginning of the germination of the chakra power system in ancient times, the ancients saw that the seal could release more powerful ninjutsu, and they all followed the trend to learn and study the ninjutsu seal.

In Naruto's opinion, in the previous life, modern people also used tools to do a lot of incredible things than the ancients. But in comparison, the strength of the body should be degraded.

Chakra is the primordial power, and the seal is the advanced tool, making it easier for ordinary ninjas to unleash ninjutsu.

Then the first eliminated the backward, but for a world with extraordinary strength, it is difficult to say between gains and losses.

This convenient system of seals has been passed down to the present day, even rigidly. Later generations were also bound in the cage of sealing, and few people walked out of this strange circle. There is a lack of innovation as a whole, and only a few geniuses can create their own ninjutsu.

Naruto even wondered: If there was no seal, would the power system of this world evolve into something else with chakra as a power seed? Not necessarily better, but two flowers, one for each branch. For example, abilities.

Gold, wood, water, fire, earth, wind, thunder, and ice are elemental or natural abilities. Illusion Spirit, Physical Physics, Blood Inheritance Limit Speciality or Mystery. Those who are proficient in everything are compound geniuses.

Kosuke was also slightly stunned when he heard Naruto's inquiry: "Probably not necessary to seal, right?" ”

Naruto Naruto: Why is "......" a questioning tone? It's not clear what a ninja has been doing for more than fifty years?

Kosuke said: "No one has ever asked this question before, and I haven't thought about it, it's all like this to learn the ninjutsu of seal release. After such a long period of cultivation, the seal has become a physical instinct. ”

"Now that I think about it carefully, it is enough for the second generation Hokage to cast a few seals of the Water Dragon Bullet Technique, and some Water Escape Ninjutsu seems to be able to be used just by raising his hand. It's not like the seal, it should be because you need to release the chakra from the acupoint in your hand. Maybe when he practiced to that level, he would be able to simplify or even eliminate the need for sealing. ”

"Well, it probably has something to do with proficiency. I used to have a few ninjutsu that I used to use a lot, and it seemed that I could just subconsciously make a seal. Of course, now that people are old, Chakra's control ability has decreased a lot, and he can't do it anymore. ”

Naruto Hakaze asked, "So, can ordinary people who have not practiced be able to use ninjutsu?" ”

Kosuke replied, "I can tell you for sure that there is no way. The complexity of ninjutsu is more than just a few seals. Enough chakra is needed. Moreover, it is necessary to control the meridian system of these chakras in the body to carry out various complex energy circulation. Chakra's ability to control is both physically and mentally. ”

"The poor physical talent is only a low control ability, but the mental power is not enough, and it is impossible to control the chakra at all. Ordinary people who have not practiced, chakra and spiritual power cannot meet the most basic requirements for releasing ninjutsu. ”

After hearing this, Naruto spread out his right hand and used chakra to control the water in the air, slowly condensing a water ball in his palm. He couldn't do it yet, but he could still do it with a small thing.

Then the water balloon twisted and changed, slowly turning into an irregular little water dragon churning and jumping in the palm of its hand, looking uncertain. Naruto smiled relaxedly, and the little water dragon shattered into a stream of water that flowed out of his fingers.

"I had guessed before. Sure enough, the essence of ninjutsu is chakra. Secondly, the mental power, the body, the meridian system, and the 361 acupuncture points located in the meridians, which are chakra energy pathways, all affect the release of ninjutsu and its effects. ”【1】

"The seal is just a supporting tool and formula that makes it easy to unleash ninjutsu. In fact, without these external movements, ninjutsu can also be successfully released. ”

Kosuke didn't blindly refute the denial, but asked curiously, "Do you have any ideas?" ”

If a ninjutsu only has a few seals, there is no need to waste the paper records of a ninjutsu scroll.

In the ninjutsu scroll that Naruto Bokaze purchased from Granny Cat, there are not only the seals of ninjutsu, but also the chak circulation method of the meridian system in the body between the seals and the seals. For example, what kind of flow and speed should the chakra use, which part of the body meridian system or which acupuncture points should be passed.

"There are 12 major meridians in the five internal organs of the human body, and in fact, there are 24 of them if they are symmetrical. A pair of meridians form an energy cycle. The 12 seals of ninja practice correspond to the chakra cycle in the 12 mainstream meridians. ”

"Because it's mainstream, most ninjutsu will use one of them or even repeat some seals several times."

"However, the meridian system of the human body is extremely complex, and there are other strange meridians and eight veins."

"In addition, these meridians are also connected, so there are also a lot of side chakra energy circulation methods."

"Different chakra cycle methods will affect the ninjutsu release effect, including attack, defense, range, form change, nature change, duration, etc. Chakra of different natures, even if you use the same chakra cycle method, will have different effects, and even ninjutsu failure. ”

"Outsiders can't learn their own ninjutsu based on the mainstream seal alone, because the trivial chakra cycle method is also an indispensable core of every ninjutsu. Unless this outsider has a special blood inheritance limit that can see the flow of chakra, such as the chakra eye and the white eye, and he must be born or cultivated with the same chakra nature. ”

"The ninja first cultivated each seal individually, so that the meridian system in the body instinctively remembered the chakra cycle method of these corresponding seals. Ninjutsu is then formed by combining these mainstream seals and side chakra cycles. ”

"If you don't practice the 12 seals, it is enough to confuse yourself if you want to control the chakra to carry out complex energy circulation in the meridian system in your body just by relying on your spiritual power. It will not be able to unleash ninjutsu, or it will be slow and inefficient. ”

"In this way, you can only use physical techniques or give full play to the basic characteristics of chakra, such as chakra toughness, invisibility with the naked eye, and changes in nature."

"On the other hand, after years of practice, the body is proficient in memorizing various Chuck cycle methods, and there is no need to seal it. As long as you directly control the chakra in your body for energy circulation. ”

"Of course, if you want to release ninjutsu without a seal, the requirements for mental power and chakra control ability are also very high."

In the end, Naruto Hakaze concluded, "After restraining my body's instinct to seal just now, I recalled the feeling of the chakra circulation in the meridian system in my body when I used the water dragon bullet technique, and directly controlled the chakra to release the ninjutsu according to this feeling. Sure enough, I'm not used to it. Power, size, time, morphological changes, and duration are all far from the seal. ”

He felt that it was harder than the Spiral Pill. Spiral pills are difficult to control outside the chakra, and the chakra circulation of the meridian system in the body is actually very simple, just export it outward. The technique of the water dragon bullet is the opposite, and the chakra cycle in the body is too complicated.

"Moreover, the reason why the water dragon bullet technique requires a lot of seals, but the power is not as great as imagined. That's because the effect of these repeated prints is reflected in the morphological change, flexibility, and continuity. ”

"It's not like it, so it can't be used in real combat. After all, the water dragon bullet technique was released in the form of a seal. ”

Kosuke said: "So you think that as long as you are proficient in ninjutsu practice, ninjutsu seals are dispensable?" ”

Naruto's eyes lit up: "No, I mean, since the ninjutsu seal is dispensable, why wait until the strength becomes stronger to use the ninjutsu, instead of practicing the ninjutsu in the form of the seal in advance?" ”

Kosuke was noncommittal: "It doesn't matter if what you say is right or wrong. Judging from the water dragon bullet technique you just used, not only can it not be used in actual combat, but it will also be very difficult and awkward. It's better to go with the flow and wait for the strength to become stronger. ”

"It's hard at the beginning. It doesn't matter if it can't be used in actual combat at the beginning, training is training, and actual combat is actual combat. Overcoming the instinct of ninjutsu sealing, I can go from easy to difficult, starting with E-rank ninjutsu. I have a hunch that before I have the strength of Kage, I will be able to use ninjutsu in the form of Muji. When I'm obsessed with confidence, it's good. ”

Naruto Naruto is confident in his mental power and chakra control. The significance of the Ninjutsu Seal is that it can reduce the difficulty of releasing Ninjutsu, and it is universal. But how can you be a genius and stand out from the crowd?

Kosuke: ",,,,,," You said that you are confident, what else can you say?

[1] Reference: The meridians and meridians are the main body of the meridian system, which is composed of 12 meridians, 8 strange meridians, 12 meridians, 15 meridians, 12 meridians, and 12 skins. The acupuncture points are located in the "meridians" - the pathways of energy (Chinese medicine has "qi", but there is no chakra, real and non-false qi, etc.).

In the human body, there are 12 meridians (in fact, there are 24 symmetrical left and right symmetrical). In addition, there is a "Ren Pulse" in the center of the front of the body, and a "Du Pulse" in the center of the back of the body, each with a special meridian that runs through the whole body.

The acupoints of the human body arranged on these 14 meridians are called "positive acupoints", and there are a total of 365 points in total

The old international standard was 361, and later there were new discoveries. The Hokage setting is also 361 (said by Kakashi Hachiki during the Chunin exam). So I suspect that Kishimoto Saishi used to quote the setting of this TCM meridian system in the past.

That's a considerable amount of money alone, not to mention that there are also acupuncture points in other places. Later, "new acupoints" were discovered one after another, and if these acupoints were all included, the total number of acupoints in the human body was far more than 1,000.

There is a saying on the Internet: It is said that ancient Japanese ninjas had a tradition of cultivating religious seals to stabilize their bodies and minds, and then Kishimoto used this setting.

Personal understanding: I don't know if the twelve seals set by Kishimoto have anything to do with the meridian system, maybe the Hokage just quotes the setting of the religious seal action, and I think it's cool and feeling, so I draw it like this.

But in my setup, the 12 seals correspond to the chakra cycle of the 12 meridians in the meridian system. The same chakra causes different ninjutsu effects, the external is the difference in the sealing action, and the internal is the difference in the way the chakra cycle is different, and even subtle differences will affect ninjutsu.

If you can release ninjutsu with just a simple seal action, the copying ability of the writing wheel eye is not necessary. Many secret ninjutsu are enough for just one seal.

So setting up the chakra cycle outside of the Twelve Canons is a side matter, but it's just as indispensable.
