Kakarot, the strongest Hokage in history!

In fact, when Yuu refined chakra according to Professor Kakashi's method just now, he felt that the process was too cumbersome and tiring. Why did he extract physical energy from 130 trillion cells before combining it with spiritual energy?

Body energy... Not only does this thing exist in his body, but there is also a lot of it, right?

There is a lot of "qi" in his body, which is the energy produced by the pure body.

Is it redundant to extract energy from cells?

So, can "Qi" be combined with that spirit?

Driven by curiosity, Yu Yu tried it. After that, he found that the combination was quite smooth, and the ratio of the two was also well controlled. After only a few minutes, Yu Yu realized that there was another kind of body in his body. Strange energy.

That ray of energy flowing quietly in the body is chakra.

"What's wrong, Kakashi-sensei?"

"Um...it's nothing, Yu Yu is extremely talented in refining chakra."

"Is this called talent? Then, does this mean that I will have a lot of Chakra in my body in the future."

"It's not certain. There are many factors that determine the amount of chakra in a ninja's body. It has a lot to do with blood inheritance, talent, and one's own diligence. Yuyu, look at your talent and parental inheritance. Come on, the amount of Chakra in my body should not be lower than mine in the future."

Youyu said in her heart, if my chakra level is only comparable to yours, then it will be too bad.

Kakashi, you are the most famous blue ninja in the ninja world. Sharingan Kakashi, you have been lying down for a week after using Sharingan once. If I do the same, I will be ashamed.

Seeing that Yuu didn't seem to like his compliment, Kakashi scratched the slightly messy silver hair on his head. After this time, he felt that he couldn't figure out what the one-year-old child in front of him was thinking. Treat Yuuha like a one-year-old child.

This surprisingly precocious maturity reminded him of another child in the village, the five-year-old Uchiha Itachi.

Itachi Uchiha mastered the family ninjutsu Fire Escape · Fireball at the age of two, excellent shuriken at the age of three, and experienced the tragedy of the World War III at the age of four...

It is obvious that Uchiha Itachi is an outstanding young genius of the Uchiha family, but it is a pity that he heard that the child is too mature, taciturn, and not good at communicating with others. gregarious.

What is the future of Uchiha Itachi's ninja?

What will Yuu's future be like?

Kakashi is not sure, but he knows that the future of the two may be very different... But there is a faint feeling that Uchiha Itachi's future road may not be smooth sailing, he may fall into darkness, or bear a huge darkness...

Yuu, probably won't embark on a lonely ninja path like Uchiha Itachi.

He got some information from chatting with Nohara Yangdou several times. Not only is this kid not taciturn, sometimes he talks a lot, and he also likes to be alone and talk to himself.

Thinking of this, Kakashi is still satisfied with the disciple in front of him.

Now that Yu Yu has easily mastered the chakra extraction, then today he began to greatly speed up the progress of teaching this child.

He began to teach Yu Yu how to better control Chakra, how to use Chakra to enhance the body's ability to move and defend. In addition, under Yu Yu's strong request, Kakashi taught him how to form seals. Simple E-level ninjutsu, clone, transformation, and substitute.

Today's teaching time is very long, so Kakashi's lunch is settled at Nohara's house.

…

After dinner, Yu Yu went back to the room alone.

He began to practice chakra extraction in the room. This time, in just three minutes, two paragraphs of text appeared on the panel in front of him. At the same time, the brain also heard the sound,

[Detecting the existence of Naruto World Chakra in your body will open the Chakra and Art section for you. 】

[Note: This section only digitizes your chakra and ninjutsu power system, the character fusion system will not provide any other help, please work hard. 】

After these two paragraphs of text appeared and disappeared, Youyu saw that there was indeed an extra module on the panel, and there were only two items on it.

"Chakra volume" and "Naruto world art".

Chakra (6/6): It is far from the most common ninja.

Naruto World's Art: Clone Art LV0 (14/100): Not yet started.

Substitution LV0 (10/100): Not yet started.

Transfiguration LV0 (17/100): Not yet started.

What are these things for?

Yu Yu looked at the data on the panel, feeling a little uncertain...

After looking at it for a while, his eyes became very bright, and he decided to try the idea in his heart. After standing still, he made a seal with both hands, "The technique of double body!" Boom, after the smoke cleared, there was an extra five or six centimeter high "Xiao Youyu".

"Little Youyu" looked at the mountain-like Youyu beside him, and fell into confusion for a while.

Sure enough, the avatar technique failed, and there was no entry.

[The growth experience of your avatar +1. 】

Come on again, bang, another little Yuyu appeared.

[The growth experience of your avatar +1. 】

Boom, [Your clone technique growth experience +1. 】

…

[The growth experience of your avatar +1. 】

[The growth experience of your clone technique +2. 】

[The growth experience of your clone technique +2. 】

"..."

Yuyu nodded secretly, as he expected, the system will not improve the experience and level of skills from fusion and fusion tasks like Kakarot's skills.

However, experience still shows an increase in numbers during the cultivation process.

This is equivalent to pointing out a more correct direction for him to practice ninjutsu.

With +1 point and +2 points of cultivation results, the latter is naturally faster, and he naturally abandons the former's cultivation method and embraces the latter.

Youyu thought, with the help of the system's digitization, his speed of practicing ninjutsu will be greatly improved. Shang Youyu has cultivated to LV2 level, LV0 level is "not yet started", LV1 level is "seeing the threshold of entry", and LV2 level is "barely entered the door".

Time flew by two weeks.

Youyu's three body skills have all been upgraded to LV4, "Beginners, small successes".

On this night, Yu Yu, who had "made a small achievement", couldn't wait to verify the results of her cultivation during this period of time. After making seals, "transformation technique", bang, after becoming the fat middle-aged butler Daisuke , and then walked to the door swaggeringly with her belly out.

The two guards at the door glanced at him and nodded to him, then let him go.

It worked! He fooled these two real ninjas!

Youyu secretly rejoiced, thinking that he could go out and play for a while, but before he was happy for more than three seconds, Minako, who was walking in the yard, looked out suspiciously, she stared, then ran over quickly, grabbed The butler's back leader lifted him up...

"Boom", the effect of the transformation technique disappeared, and Yu Yu's little child's body and his slightly depressed face appeared.

"Where do you want to go so late!"

Minako walked back quickly with her son in her arms, and said with a cold snort, "You still want to fool a Jnin like me with your clumsy transformation technique?"

However, at this time, she was far more surprised than she seemed.

A few days ago, Kakashi told her that Yuu's talent in ninjutsu was the highest he had ever seen, and that he would visit more often in the future. At that time, she thought Kakashi was talking about making people beautiful. The polite words, or Kakashi's knowledge is less...

Tonight, when she took a walk in the yard, she was surprised by this son.

Minako didn't blame them when passing by the two red-faced and ashamed guards. It is indeed a ninja's shame to be deceived by such a child with the transformation technique, but her son is not an ordinary child, and he can understand...
