Ling returned home in the evening.

"System, how long does it take for the eye to evolve?" Ling asked in his mind.

"Evolution in about five minutes."

"It seems that the evolution of the writing wheel eye in the original book can be completed in a moment, why did it take me so long." Ling was a little puzzled.

"That method is more appropriate to describe as a breakthrough, the host evolves through the growing eye, not only the pupil power is stronger, but also the potential of the eye can be well improved."

"Huh? By potential, you mean ......"

"The ability to open the kaleidoscope, and the ability to promote the eye of reincarnation."

"Well, breakthrough...... No, evolve! ”

In an instant, Ling's originally black pupils turned into single-hook jade writing wheel eyes, and he felt as if he was bathed in sunlight, and a warm feeling flowed throughout his body.

A warm current in his mind slowly flowed to his eyes, and then a trace of golden aura spread to his whole body.

Ling could feel the cells in his body as if they were trembling with excitement, and the chakra gushed out wildly, and this comfortable feeling made him close his eyes unconsciously.

Five minutes later, Ling Neng felt that his eyes had changed, and the changes in his body had gradually subsided.

Opening his eyes, two blood-red magatama slowly rotated around his pupils, exuding a strange and intense aura.

Double hook jade writing wheel eye, open!

Ling shook his hands, he could feel that his strength had increased a lot now, and the amount of chakra had also increased a lot.

"System, show my current properties."

"Ding!

Class C ...... (In the future, ordinary C-level ninjutsu and even B-level ninjutsu will not be listed, not relying on the number of words in this water.) Everyone knows the chakra attribute of the character, and simple ninjutsu can be used casually OK)

”

"Have you reached the level of the upper ninja?" Ling was a little excited in his heart.

The Naruto World's assessment of strength is very vague.

It's like a shadow, the only thing that can be called a shadow in the entire ninja world is the shadow of the five great ninja villages, and of course, there is also a star hidden village that doesn't know the height of the sky.

However, there are countless people whose strength has reached the shadow level, and even in the later stage, many powerful and perverted ninjas are only titled medium ninjas.

However, with systematic evaluation, he does not have to worry about misjudgment, and he can also use this to gain the upper hand in strategy.

……

Early the next morning, the three of them came to the training ground together, and after a while, Uchiha Hara Takeshi also rushed over.

"Teacher, do you want to teach us ninjutsu?" Rei Kitano asked impatiently.

As a child of a civilian ninja, she knew very little about cultivation, or in her eyes, she only had to learn what ninjutsu she wanted to do.

However, Hinata Fumino, who was born in a big family, has also learned the common sense of cultivation under the guidance of the family.

Hearing Rei Kitano's question, Uchiha Haramu snorted and said with a smile: "You only learned some basics in the ninja school, and you have a lot to learn in the future." ”

Looking at Kitano Rei's puzzled eyes, Yuan Wu didn't hang her appetite, and continued: "What I'm going to learn today is the control of Chakra. ”

"As we all know, if you want to use ninjutsu, you have to consume chakra.

For example, in the case of the same amount of chakra, some people can use the doppelganger technique ten times, while some people will run out after using five chakras.

Why is that? Seeing that the little ghost in front of him obviously didn't respond to his intentions, Uchiha Haratake scratched his head, and then said:

"That's because his control over the chakra is too rough, which causes the chakra to be wasted, which not only does the ninjutsu he uses not work well, but it is also not conducive to long-term fighting.

So your first lesson is to learn how to control the chakra with precision. ”

"Teacher, isn't chakra refined through refinement, how should I cultivate?" Rei Kitano asked.

"The teacher was talking about tree climbing and treading water." Hinata Fumino spoke.

Uchiha Haratake nodded and said, "Fumino, you and Ling have already been trained to climb trees and tread water. Seeing the two nodding, he continued:

"But Ling's starting point is low, so I can only help her more."

The two nodded in agreement.

Then Yuan Wu took the three of them to the back mountain, which has a spacious river and a small pool, which is perfect for cultivating treading water.

Takeshi Hara also personally demonstrated climbing trees and treading water, and talked about the essentials of cultivation, but mainly for Kitano Rei.

Rei Kitano realizes that chakra is so useful, and it is as if the door to a new world has been opened.

Her talent for chakra control is still very good, and she can climb to the top of the tree steadily in just a few times.

It seems that she really has the potential to become an excellent medical ninja, Ling said secretly in her heart.

"Alright, let's explain Chakra to you." Uchiha Haratake's tone became serious.

Ling also listened carefully, although he was familiar with the original work, he really didn't know much about cultivation.

"Chakra is a special energy produced by the combination of human spiritual energy and physical energy, which can be refined by special methods.

The attributes of chakra are divided into five types: fire, water, wind, earth, and thunder, and everyone is born with a great affinity for one or even several of them, which can be tested with chakra test strips. ”

As he spoke, he pulled out a few test strips, and then he injected the chakra into the test strips, which spontaneously ignited in the air.

"Inject chakra, and the test strip burns to mean that I have chakra with fire attributes."

"Teacher, I saw you use Tu Dun that day, aren't you a dual-attribute chakra?" Hinata Fumino said with some confusion.

"I only have one chakra of the fire attribute, but to the level of upper ninja, basically everyone will master two or even more attribute chakra." Uchiha Haratake explained.

"Okay, let's try what kind of chakra you are." After Yuan Wu finished speaking, he handed the test paper in his hand to the three of them.

"Teacher, I'm a wind attribute chakra," Hinata Fumino said.

Uchiha Haratake silently withdrew a test strip.

"Teacher, I am a chakra with two attributes, fire and wind." Ling said slowly.

Takeshi Uchiha Hara was full of black lines and handed the last test strip to Rei Kitano.

After Rei Kitano instilled Chakra, the test strip was wet, and she looked up at Takeshi Uchiha in confusion.

Yuan Wu said with a smile: "The test strip is wet, which means that you have a chakra with water attributes." ”

"What attribute chakra possesses can be cultivated accordingly, and chakra nature changes are divided into seven types: fire, water, wind, earth, thunder, yin, and yang.

After mastering the nature change, the power of using ninjutsu will be greatly enhanced, and if the two attribute changes are fused, a new blood inheritance limit will be formed, and the three fusions will form a blood stain elimination. ”

"Teacher, aren't my White Eyes and Ling's Writing Wheel Eyes the Blood Inheritance Limit, and what's going on with the changes in the Chakra attributes of the Yin and Yang attributes?" Hinata Fumino asked.

Uchiha Hara Wu Kankan explained: "The white eye and the writing wheel eye are both born blood inheritance limits, and the blood inheritance limits formed by attribute fusion are acquired, and the two are strong and weak.

As for the chakra changes of the yin and yang attributes, the yin attribute represents the power of the spirit, while the yin retreat can create the form invisibly; Yang attributes represent the strength of the body, and yang escape can breathe life into the body.

The doubling technique of the Akido clan is the application of the change of the yang attribute, while the shadow secret technique of the Nara clan is the chakra change of the yin attribute. ”
