Identifying a possible shortcut to practice, Aoyagi turned to think about the possible mechanism of action of these two secret techniques.

If we combine the previous inferences and use chakra to nourish the body's cells, is it to actively let the chakra escape in the corresponding place, so that the cells can store more chakra factors, and the combination of chakra factors and cells will strengthen the cells, and then passively strengthen physical fitness and enhance physical strength? If that's the case, then the body of the immortal is the body rich in the chakra factor? And the eye of the fairy is the eye and brain rich in chakra factor?

Assuming that the chakra factor is the same, then when using the chakra factor to enhance physical fitness, the nature of the chakra should not be the focus, but the amount of chakra emitted. In other words, there is no need to change the nature of chakra when strengthening the body, just use chakra trophoblasts.

Unless the chakra factor that is finally converted into different chakras has different effects on the cell, it is necessary to change the chakra properties before the chakra is emitted to achieve the desired effect (even if the cells are strengthened in the desired direction).

According to the description in the secret arts, the nature of chakras used for trophoblasts is indeed different, one is more physical, and the other is more spiritual.

The inference (no need to change the nature of the chakra, directly using the chakra to strengthen the body) does not correspond to the reality (the body is strengthened by the chakra after the change in nature), and the assumption is wrong. This means that there is not only one type of chakra factor, but different species. Thinking of the bloodstain boundary, perhaps, the chakra factor contained in different human bodies is different, and the chakra factor in the human body with the bloodstain boundary is obvious.

When the ancestors developed new chakra properties, the continuous use of these new chakras continued to leave the corresponding chakra factors in the cells, and these factors were passed on to the next generation like genetic material. In this way, the next generation activates these specific chakra factors, and will develop the corresponding nature of chakra, which is the awakened bloodstain boundary.

And some people do not inherit the bloodstain boundary, because the concentration of the corresponding factor is insufficient or even non-existent. The higher the concentration of the corresponding factors, the faster the awakening, which means that the talent in this area is higher.

As for the civilian ninjas, basically the chakra in their bodies is a relatively ordinary chakra factor.

Thinking about it this way, Aoyagi felt that it seemed to make sense, and he could barely be logically consistent. However, being logically self-consistent only means that this set of theories may be true, and the actual situation needs more experimental verification and observation. If the chakra factor can be found, it will be much more persuasive.

There is vague information in the memory of the continuous reincarnation of Indra and Asura's chakra. Perhaps, this reincarnation is the transmission of their chakra factor. It's just that these chakra factors are highly contagious and can cause the host to develop and change in its own direction.

Thinking about it, Aoyagi suddenly felt that this thing was becoming more and more like a virus. The virus is able to affect the infected cells and cause them to develop in a different direction, creating a more suitable environment for them.

Such cranky thinking is just a hobby of Aoyagi, a way to eliminate (crazy) grinding (water) time (words) (numbers), and these inferences are not necessarily correct, just for self-amusement.

But maybe one day, these hypotheses and theories will come in handy?

Aoyagi still has some expectations for this.

………………

The next morning, when Aoyagi arrived at the classroom, there was no one there. Picking a window seat at the back, Aoyagi took out a scroll from his bag that recorded the geography of the ninja world, and hurried to study.

Ninjas always need to go out on missions outside the world, and it's important to be familiar with the geography of each place. If you are familiar with the topography of each place, you will be able to make better use of the external environment to accomplish your own goals.

After Mr. Araki's lecture on intelligence yesterday, Aoyagi also valued this knowledge that did not seem to directly increase combat effectiveness. Anyway, if you have nothing to do in school, you will be idle, so you might as well study.

Time flies by in reading, and before you know it, the classroom is already full. And the teacher also entered the classroom.

However, the teacher who entered the classroom was not Araki, but the teacher who appeared with Araki before.

In the last rush, Aoyagi didn't take a closer look at the teacher's appearance. Short brown hair, sky blue pupils, resolute eyes, straight waist, some military temperament.

"I'm Sugimoto, and in the future, I'll be in charge of your class with Araki-sensei. I will teach today. ”

Without any pause, Mr. Sugimoto immediately began to lecture.

"Today I will talk about the history of Konoha Village. During the Warring States period, various ninja families fought each other, and the situation was very chaotic. In the midst of the war, the people's lives were very difficult...... And the original Hokage-sama, Senju Tsuruma, teamed up with Madara Uchiha, based on the Senju and Uchiha clans, and together with other ninja families, they founded Konoha Village in the Land of Fire, creating a system of one country and one village, the country supports Ninja Village, and Ninja Village provides military power for the country, that is, ninjas. After that, other major ninja villages were also established. At this point, the Warring States period ended. ”

After that, the situation in the world stabilized a little bit, and the killing between families decreased. But the peaceful days didn't last long, and the First Shinobi War broke out......"

………………

"That's the end of the morning class, an hour break."

The students ran out of the classroom like birds out of their cages.

Aoyagi slowly took out the bento box in his bag, walked to the shade of the tree, sat down cross-legged, and ate the bento he had prepared in the morning.

A few chopsticks in front of the cold one, Aoyagi's appetite was greatly reduced. In his previous and present lives, he was used to eating hot meals, and when he ate cold meals, he subconsciously felt that he would have a stomach upset.

Cold food is inherently difficult to digest. The advent of cooked food has helped human evolution, so why do we regress to eating cold rice now?

Ah, why isn't there a microwave, it's hot with a ding, how convenient! How to solve the problem of lunch later?

Just when Aoyagi was unhappy because of the bento, Chisato Oe and Twilight came over again.

"Aoyagi-kun, so you're here. Let's have lunch together. ”

Far away, Dajiang Qianli was shouting there.

Although Aoyagi wanted to pretend that he didn't see the two of them, he also knew that it was meaningless, so he waved his hand and reluctantly responded.

Sitting down next to Aoyagi, the two took out bread and prepared to eat.

Looking at the good-looking bento in Aoyagi's hand, and comparing it with the bread in his hand, Chisato Oe was very sad.

"Alas, Aoyagi-kun, you're fine, my aunt made a bento for you. My father was busy opening a shop and didn't have time to prepare a bento box for me. Kawamata's parents were also very busy, so we had to eat bread. ”

Although the lunch break was only one hour, many people close to home ran home to eat.

However, Chisato Oe's father was busy with things in the store and didn't have time to go home and cook. And the situation of Kawamata's family is similar, in order to support several children, parents work from morning to night. They had to eat bread at noon.

"Well, I did it myself."

"Huh?" Chisato Oe was very embarrassed and said with a dry smile, "Really? Haha, Aoyagi-kun can cook by himself, it's amazing, hahaha......"

Seeing that Aoyagi didn't answer and ate silently by himself, Chisato Oe stopped laughing in embarrassment.

However, after being embarrassed for two seconds, Chisato Oe suddenly said with great interest: "Aoyagi-kun, I wonder if we can try your cooking skills?" Like, tonight? ”
