Aoyagi summed it up and said that the most efficient way to determine the chakra structure and its corresponding functions is to find several ninjutsu with the same function, compare their overall structures, find the same parts, and experiment, so that the chakra structure can be quickly determined.

From then on, in his own eyes, ninjutsu is no longer a complete whole, but is composed of different functional modules, or chakra structures.

Starting from the chakra structure, you can get in touch with the composition of ninjutsu more essentially. If we can get together enough chakra structure, perhaps, we can find more essential laws from it, and then understand the mechanism and laws of chakra action more deeply. If we can really get to this point, we may even hope to develop a chakra structure that has never appeared before.

I don't know if there will be such a day, although there is not much hope, but Aoyagi is looking forward to it.

Suddenly, her stomach growled, interrupting Aoyagi's beautiful fantasies.

Standing up, Aoyagi stretched his waist and said to himself, "Alas, I actually forgot to eat dinner, but fortunately, I still have some things in store at home, so let's cook some and eat them." "Living alone for a long time, Aoyagi sometimes talks to herself.

I looked at the clock, it was already nine o'clock, and after eating and taking a bath, it was time to go to bed.

Hurriedly ordered some noodles, added some eggs, greens, and minced meat, and Aoyagi filled his stomach.

After taking a shower, Aoyagi lay down on the bed. It was very laborious to draw a chakra operation diagram for a long time, and as soon as she withdrew from the state of hyperactive research, Aoyagi felt very tired. As soon as his head touched the pillow, he was groggy and soon fell asleep.

As always, Aoyagi came to the spiritual space in his sleep.

As Aoyagi expected, on the shelves where various materials were stored, there were three more chakra charts that had just been drawn today. Writing and drawing using words from previous lives can indeed add information to the space.

As the spirit grows, the amount of time Aoyagi can spend in space also increases, and it is just the right time to use this time to study. After all, researching, exploring, and thinking about new things is very time-consuming, and if you do it in a space, it will not take up your time for cultivation.

Aoyagi made up his mind that in the future, except for those studies that would require the use of chakra, the rest would be carried out in the space as much as possible.

Placing the three chakra charts, Aoyagi carefully compared their differences, and took a pen to make notes.

(Small objects such as pen and paper have been successfully transformed into space.) Perhaps because of the mental space, Aoyagi can arbitrarily modify and delete what he writes in the mental space, which is also convenient for him to record his inspirations and revise his experiences. ）

Some of the three drawings are obviously similar, but the details are still a little different, and Aoyagi took the draft, and kept scribbling and revising the similar parts of the three pictures while thinking. It took a long time to finally identify several possible structures.

After that, it's about analyzing other ninjutsu, trying to add these structures to it, and experimenting one by one to see if you can make ninjutsu have the ability to track.

The functions of the ninjutsu of the retreat are mostly similar, and the structure should be the same. Start with the escape technique, it should be easier to analyze.

…………………………

During this time, the ninja school's curriculum was basically for students to practice stand-in techniques, or to conduct practical courses such as shuriken throwing and physical arts. In Sugimoto's theory class, most of the lectures were about ninja rules, certain tips, detection methods, and the like, and he didn't continue to teach the students an advanced version of the stand-in technique.

Aoyagi guessed that perhaps Sugimoto felt that the stand-in technique that could switch ninjas and stand-ins was too much for them now, and there was no need to teach it.

It's just that Aoyagi has already learned the low-level version of the stand-in technique, so he waited for Sugimoto to teach advanced content, who knows that he hasn't talked about it.

The stand-in technique that can replace oneself with a stand-in is the stand-in technique in Aoyagi's impression. It is very useful to be able to avoid the deadly blows of the enemy.

The current castrated version really has little practical effect. It's just a matter of using a stand-in to deceive the enemy, and you have to carry out a cumbersome operation - you take the initiative to hide yourself, let the stand-in act, and you can't let people find out that the two have been replaced. Without the ability to send himself off the battlefield, the value of the stand-in technique in Aoyagi's eyes plummeted.

Aoyagi, who couldn't wait, went into the basement, and after rummaging through, he got the scroll that recorded the stand-in technique.

Sure enough, there is an advanced version of the stand-in technique recorded in the scroll, and after reading it carefully, Aoyagi probably understands why many ninjas in the original book do not use stand-in techniques to dodge when faced with deadly attacks.

The advanced version of the stand-in technique, the key to making the ninja and the stand-in switch is on the chakra.

The advanced version of the stand-in must be tempered with a chakra that gives a static but conspicuous feeling (good for one's own perception, and perhaps only the caster's own perception is obvious, but not in others' perception).

When you plan to use the stand-in technique, you first perceive the chakra that you have left on the props in the distance, and then use the restless but vague chakra to seal (of course, if the chakra has strong control ability, it can also be used without a seal, and the running route is not complicated, but the difficulty is the change of the chakra itself).

After the seal is completed, the self and the stand-in will be connected, and the two will attract each other, pull each other, maybe through something like a spatial channel, and swap places. At the same time, the chakra of the self will gradually become static and conspicuous, and the chakra in the avatar will become restless and obscure, and the wood will become a stand-in. Then, the chakra inside the stand-in begins to consume rapidly, and once the chakra is consumed, the stand-in will turn back into wood even if no one strikes it.

(I don't seem to have a white-eyed stand-in technique in my impression.,I don't know if I'll see through)

After using the stand-in, the ninja will have a process such as regaining qi, and it will be difficult to control the body for a short time, and the chakra will also remain stationary. The duration varies from person to person, but it usually takes a few seconds to recover, and the shorter ones are less than a second.

Back to the question just now, why do so few people use stand-ins?

Judging from the content on the scrolls, the advanced version of the stand-in technique should be more than just E-rank ninjutsu. It is more demanding of chakra, and there are relatively few ninjas who have learned it. In addition, there may be many ninjas who don't even have the opportunity to get in touch with this ninjutsu.

In addition, although the advanced version of the stand-in technique allows you to switch between yourself and the stand-in, it takes a lot of time from realizing that the attack is coming to the time when you are dying to activate the stand-in, and many times it is too late.

After all, the advanced version of the stand-in technique has relatively high requirements for Chakra's control ability, and when being raided, if you can't react, you can't dodge directly, and you can only dodge by using the stand-in technique, so the time left for the ninja to use the stand-in technique must be very short. To complete the stand-in technique in such a short period of time, the requirements for chakra's control ability are higher, which sifts out a large number of people.

Finally, if you want to use the stand-in technique, you need to prepare props in advance and place them in a safe place, and many ninjas have not done a good job of arranging them, so they naturally can't use them.

I didn't expect that there were so many low-level ninjutsu in this impression. Sure enough, you can't underestimate anything, and don't let the label on it affect your judgment of it.
