Uchiha Yu's maverick behavior slightly surprised the executive ninja, but that's all.

It is not uncommon for the ninjas in Konoha Village to be alone, especially among the upper ninjas, there are many ninjas who perform tasks alone.

Ninjutsu has been around for thousands of years, and after the development of generations of outstanding ninjas, a thriving ninjutsu civilization has been formed.

In particular, after two ninja wars, more than 100,000 ninjas have been verified on a large scale with their lives, and the middle and low-level ninjutsu have been perfectly summarized, forming a mature ninjutsu system.

The strength of the lower ninja and most of the middle ninja is limited, and they cannot master the complete combat system alone. As a result, squads formed according to the ninjutsu system gradually became popular, and the formation of squads of middle and low-level ninjas could not only make up for their weaknesses, but also help them play to their strengths. A good ninja squad can not only crush ninjas of the same level, but even challenge more advanced ninjas to a certain extent.

The large-scale ninja village thus formed an unshakable advantage, completely overpowering the organizational form of the ninja family.

But when the ninja grows up to the upper ninja stage, everything is different again.

The development of B-rank and A-rank ninjutsu is in the ascendant, and many new ninjutsu are being developed every year, and every few years there are legendary ninjas who bring fire to several ninjutsu.

Among them, the second generation of Hokage who passed away in Konoha Village is an outstanding representative of the development of advanced ninjutsu and even forbidden arts, and most of the forbidden jutsu recorded in the Book of Seals of Konoha Village is said to have been developed by him, and the remaining few are the traditional ninjutsu of the Thousand Hand family and the sealing technique of the Uzumaki family.

Moreover, after the death of the second generation Hokage Senjutsu, there has not been a master in the ninja world who can summarize advanced ninjutsu, and advanced ninjutsu cannot form a unified standard.

If the advanced ninjutsu is not standardized, the development of the advanced ninja will be strange, and the difficulty of matching each other is extremely high. For powerful ninjas, it is more convenient to go on missions alone than to team up.

A few years later, when the three generations created momentum for Bo Feng Shuimen and arranged for Shangren to give him a hand, there was a very embarrassing situation, and no one could keep up with the speed of Shuimen.

In the end, he had to face the enemy alone, and while it was a miracle to kill fifty Iwakure ninjas in an instant, he also lost the opportunity to share his exploits with his subordinates.

The four generations of Hokage have only one cronies, and he was easily overshadowed by Konoha F4, which is inseparable from the situation where he was forced to eat alone on the battlefield.

No one likes a leader who doesn't bring benefits.

In short, the administrative ninja didn't find it strange for Uchiha Yu to move alone, he simply recorded the information that there was no squad, and then went to ask the next middle ninja.

Soon all the formalities were completed, and the new middle ninja dispersed in a hurry.

Uchiha Yu left without a trace, but instead of rushing home, he walked slowly along the street, testing his ability to know the mind and feel the benefits of taming the heart ape at first.

The heart ape is not real, but a spiritual level of spirituality, but it can really affect Uchiha Yu's body, causing him a lot of trouble.

So after hammering the giant ape into a golden snub-nosed monkey, the digestion of the giant ape's body also brought great benefits, that is, the strengthening of the heart veins.

Uchiha Yu knows that biologically, bone marrow is the manufacturing factory of blood, but in the large system of the human body inherited from China, the heart vein is the source of qi and blood. If the heart is strong, the qi and blood are full, and when the qi and blood are full, all the veins are connected, and if the whole veins are connected, all diseases will not be born.

Now Uchiha Yu's experience tells him that the growth of the heart is not only as simple as not being sick, but also the increase in bones, muscles, and chakra activity. On top of that, his eyes had a feeling of swelling and coolness at the same time, like ......

It's like the afternoon of the successful foundation building, and the feeling of the writing wheel eye evolving from two hooks to three hooks.

At that time, it was not so strong, because he had experienced earth-shaking changes, his whole body had a similar but more advanced feeling, and the whole person had a refreshing feeling of a jump in the level of life, and the feeling in his eyes was ignored by him.

But Tsukiki also made his memory stronger, and now that he thinks back to it, all the feelings he felt a few days ago are vivid, so he can be sure that the eye symptoms that appeared after leaving the Hokage Building are a good thing.

The Uchiha family's blood inheritance limit is famous in the ninja world, and the Uchiha who opened the writing wheel eye is known as having no solution, and can only win by two people.

Uchiha Yu couldn't help but fantasize, could it be that he could awaken the kaleidoscope during the foundation building period?

Eighteen-year-old kaleidoscope, that's really hanging.

But in the blink of an eye, Uchiha Yu dismissed the idea.

First of all, the feeling of coolness and bulging in his eyes was not strong, the strength of strengthening and growth was far less than the day when the foundation was built, and the ascension of the two-hook jade to the three-hook jade was much worse than the awakening kaleidoscope. This time it can't be an awakening kaleidoscope, at most, it is because the strengthening of the heart veins directly strengthens the spirit, thus indirectly improving the pupil power.

Secondly, although the kaleidoscope writing wheel eye is a good thing, a good thing must be something that you can bear before it can be considered a good thing.

In the era of peace in the previous life, in the social environment of the continuous improvement of the legal society, a small goal is a very dangerous thing for ordinary people.

What's more, the blood inheritance limit of this extraordinary power can directly threaten lives.

Kakashi Hachiki, who became a middle ninja at the age of nine, and reached the top at the age of thirteen to become an upper ninja, what a talent against the sky.

After implanting a writing wheel eye, it became mediocre, and even suffered from the lack of chakra, so that people did not enter the ranks of the shadow level in middle age.

The Uchiha clan is also limited, Uchiha Obito and Uchiha Itachi are both geniuses who awakened the kaleidoscope at the age of thirteen or fourteen, but they are also in trouble after awakening the kaleidoscope.

Obito can only rely on the white jue half of his body to sustain his life, and after he completely adapts to the white jue in his thirties, his strength reappears to increase.

Uchiha Itachi was covered with injuries, and the kaleidoscope writing wheel eye was obviously used very carefully, but he was still reduced to almost total blindness, and he came to the end of his life because of his physical collapse as an adult.

Uchiha Yu feels that his physical fitness in the foundation building period is not enough to support the consumption of the kaleidoscope writing wheel, and if he really awakens, it will become a huge burden and affect the progress of his foundation building.

He is the middle ninja, and for the combat needs of the middle ninja, the three hook jade writing wheels are more than enough, and there is no need to pursue combat power beyond endurance.

Uchiha Yu felt the changes in his body and eyes, and at the same time, his mind jumped endlessly, and it was inevitable that he would ignore his surroundings.

Of course, such a wandering mind is not a big problem, the overall environment of Konoha Village is very safe, and there is no surveillance and assassination plan against him in the roots, so there will be no danger to his life.

Ordinary people on the street have no problem, even if they pay full attention, with the instinctive reaction of his body, he can automatically avoid people who are running.

But the ninja who was running at full speed was an exception, and just as he was walking through the bustling bazaar and into the confines of the Uchiha clan, a ninja slammed into his arms.

Uchiha Yu only felt a sharp shock in his lower abdomen, and his breath almost split, and his thoughts quickly returned, and his hands directly touched out Chibon and Kunai, making a defensive gesture.

Seeing clearly the person who had bounced off him, Uchiha withdrew his weapon and slapped him the head.

[Hey, why did this hand move on its own? 】
