Aoyagi took out a wooden stake and tried to inject a static chakra, and after more than ten failed attempts, he finally succeeded in making the stake into a stand-in tool.

After simulating the use of the special chakra seal a few times, Aoyagi sensed the chakra inside the wood and began to seal it officially.

Stand-in!

In an instant, all of Aoyagi's perceptions were blinded, and in the next moment, he had appeared where the wood was just now, and his original position had been occupied by another self, and it was his own movements from the previous moment, seamlessly connected. If your true body is replaced in the dark, it is really difficult to see that you have been replaced.

Aoyagi stood still and reflected on the feeling of using the stand-in technique, and summarized the performance he had just performed, thinking about his own shortcomings.

After all, if you learn the stand-in technique well, you can save your life at a critical moment, and Aoyagi attaches great importance to this ninjutsu.

Although the speed used to unleash the ninjutsu is fast enough, it is still not enough, and in the face of a sudden attack by the enemy, it is not necessary to complete the ninjutsu before the attack arrives. The use of ninjutsu just now was done without interference and with full concentration. However, in actual combat, you have to keep an eye on your surroundings at all times, and you will be disturbed by the environment, so you have to carry out anti-interference training.

In addition, it is necessary to find out the consumption of chakra by the stand-in technique, and ensure that there is chakra to use the stand-in technique at all times. Maybe the farther away you are from the prop, the more chakra you consume? I'll try it out later. If you don't know how much the stand-in technique consumes on the chakra, and you don't find out that the chakra is not enough when you use the stand-in technique at the moment of life and death, then it's over.

You have to make a plan in advance, how to hide the props during the battle, and it is best to be able to create a stand-in technique by pressing on the tree as Sugimoto sensei said. At this level, you don't have to worry about running out of props when you're in the forest.

In the end, if you can use the stand-in technique without a seal, it will be perfect.

Returning to the house and taking note of these shortcomings, Aoyagi made a corresponding practice plan and resumed the practice of the stand-in technique.

……………

In the practice and development of ninjutsu day after day, time flies.

On a weekend morning that was no different from usual, in the bright room, Aoyagi, who was already in the sixth grade, tore off his calendar.

Looking at the new month, Aoyagi suddenly realized that there were only a few days left before graduation.

When I recalled that when I first recovered the memory of my past life, I was dazed, overwhelmed, and worried, but now I am confident and steady, and my mentality is calm, and the change is really not small. Years of practice have brought not only enhanced strength, but also a good attitude.

Of course, in the past six years, the improvement of his own strength has become more obvious.

First of all, physical fitness and mental strength, with the help of arcane techniques and long-term exercise, they have been significantly enhanced. As Aoyagi approaches the stage of rapid growth, the rate of physical fitness enhancement becomes faster, and the speed of chakra improvement also increases.

Roughly estimated, his current chakra amount has reached the level of the middle ninja, and the physical fitness is the same, as for the mental strength, even in the middle ninja, it is also a leader.

And although with the help of the sparring of the wooden stake and the shadow clone, the physical skills and shuriken skills have improved significantly, but due to the lack of actual combat, the combat effectiveness of these two aspects should not be comparable to that of the middle ninja. However, as long as you officially become a ninja, after you start performing tasks, you will be able to improve your combat effectiveness soon after making up for the actual combat experience.

In addition, with the enhancement of the modified secret technique, Aoyagi's five senses have also been greatly enhanced, improving his detection ability. Although it can't compare to a detective ninja with a pupil technique or a family secret technique, but the extraordinary five senses cooperate with each other, and there is no shortcoming, coupled with the skills and knowledge of concealment and tracking taught by Araki, Aoyagi believes that he can be regarded as a reconnaissance ninja, or a more professional one.

To Aoyagi's surprise, his ability to perceive chakra has become much stronger. This may be due to the fact that as the body grows and the mystical arts are strengthened, Aoyagi's spirit becomes stronger and more sensitive, which in turn enhances his perception ability.

Now, if a ninja is exercising vigorously or unleashing ninjutsu within a kilometer, Aoyagi can sense the chakra fluctuations on their bodies. And when the ninja was in a resting state and deliberately restrained the chakra aura on his body, Aoyagi could only sense their chakra fluctuations at close range.

Even so, the ability to perceive chakra gives Aoyagi the ability to detect from a distance, making up for his shortcomings in this regard.

As for chakra control, Aoyagi has already completed the practice of climbing trees and treading water, and later he often practiced ninjutsu, trying to develop and modify ninjutsu, and would find a certain amount of time every day to use difficult cultivation secret arts.

Over time, this can be regarded as the most obvious improvement in the past six years, and it is also Aoyagi's biggest reliance. Only a strong enough chakra control can support his transformation and development of ninjutsu, which is also the most important part of his combat power.

In terms of ninjutsu, over the years, in addition to the ninjutsu mentioned earlier, Aoyagi has successively learned some new ninjutsu, mainly the advanced ninjutsu of water escape and earth escape, and also practiced some simple illusions.

In addition to learning ninjutsu, with the establishment of new efficient analysis ninjutsu methods, Aoyagi analyzed the learned ninjutsu and obtained a lot of related ninjutsu function modules. According to these results, Aoyagi researched and transformed some corresponding variant ninjutsu, among which water escape has the most types, followed by earth escape, and there are some other ninjutsu. I won't go into detail here, but I'll talk about it later when it comes up. These mutant ninjutsu are where his confidence lies.

From the worry when he first came to this world to the current eagerness to try, as his strength increases, Aoyagi has begun to look forward to the moment when he will officially become a ninja and show his strength. Only in actual combat can we determine our current strength level and provide reference for future actions.

In general, Aoyagi is now a ninjutsu-type ninja who holds a variety of self-developed ninjutsu patents and is good at tracking and disappearing. It's just that he hasn't practiced the silent killing technique, otherwise it would be difficult to find his traces at night with the concealment technique he had transformed.

After a rough summary of his situation, Aoyagi is more confident that he will survive the big crisis in the future.

Now my strength is okay. And with the arrival of the growth period, his physical fitness and chakra amount will definitely grow faster with the help of secret arts.

In addition, the good foundation laid before gave Aoyagi a strong chakra manipulation ability and was able to learn ninjutsu very quickly. At the same time, he has stored a lot of information on the development of ninjutsu, accumulated a lot of relevant experience, and developed new ninjutsu much faster.

What he lacks most now is inspiration to develop ninjutsu. As long as he has new and better ideas, he can develop powerful ninjutsu relatively quickly, and learn it, and then increase his own strength.
