Red hair is easily reminiscent of the Uzumaki clan, just as black hair and black eyes are reminiscent of the Uchiha. Although the age of the world is only twelve years old, her knowledge has surpassed that of many adults.

The world has long noticed that the hair color and eye color of ordinary people are almost all black. Ninjas, on the other hand, have a wide variety of hair colors and eye colors. So, the world began to think about it for itself. What makes a ninja's hair and eyes appear different colors? As a result, the world can only conclude that it is the power of Chakra.

As far as is known, Yin Escape is a method of driving mental power with will, while Yang Escape is a method of driving physical strength with will. In the records of the Uchiha clan, the ancestors marked mental strength in red and physical strength in blue. In this way, they attribute the red writing wheel eye to the power of the mind, which is the ultimate of spiritual power. There is nothing wrong with this conclusion! There is some truth to it, but it is deeply flawed. As a result, the world will also pay attention to the physical characteristics of other ninjas during missions. Then, it really let the world sort out a rule about hair color and pupil color.

As we all know, the ninja's chakra is inherited from his parents, and the traits of the chakra are also inherited by half of the traits of their parents. This way of inheritance also results in a variety of chakra characteristics. In the study of the world, warm pupil colors, such as red eyes, represent the abundance of spiritual power, that is, the abundance of spiritual power. The cold color of the pupil represents the strong control accuracy of the spiritual power and the high sensitivity of the spiritual power. After talking about the eyes, let's talk about hair color. The hair color represents the strength of a ninja's body, and the warm hair color represents the abundance of body strength, that is, the vitality is strong. The cool hair color means that the control of body strength is strong and sensitive, and the possibility of such people creating the blood limit is also higher than that of ninjas with warm hair color.

According to the world's own research on the theory of hair color and pupil color, she can clearly get all the information about a ninja's chakra characteristics. On the other hand, the world already knows the roots of the other party. And for ninjas, the importance of their own information goes without saying.

Looking at the two red-haired and green-eyed Wind Demon ninjas in front of them, the world naturally got the information about the two of them. The red color of their hair is the ultimate color of warm colors, which means that their physical strength will be much higher than that of ordinary people. And the green pupils have not yet reached the extreme of a cold color like blue. Therefore, the control of their mental power will be relatively strong. However, this strength has not yet exceeded the level.

Although this set of detection methods does not say that there are all kinds of tests, but for now, the credibility is still relatively high.

"Magnetic escape - sand and rain", with the provocation of the world, the younger, about sixteen or seventeen-year-old boy, took the lead. And this shot is a magnetic escape ninjutsu. The principle of the technique is to take the desired sand from the desert on the ground, divide it into several parts, and then press it tightly into a ball, shooting towards the world at a speed that can barely keep up with one eye.

"Hmph~!" The world chuckled, and instead of activating the thunder element, she dodged the cannonball-like sand with only the dynamic vision of the writing wheel. Although the young ninja had a large range of techniques, he still couldn't touch a corner of the world. Chakra is made up of mental and physical strength, and it goes without saying. Among them, the spiritual power determines the form and accuracy of the technique. The strength of the body determines the nature and intensity of the operation.

"This ninjutsu is to strike an extremely large number of sand cannonballs at an area, it's too wasteful of chakra!" While dodging, the world made its own evaluation of this ninjutsu, "This kind of control accuracy should already be the limit of the green pupil, looking at the chakra that permeates the two of them, then the information I guessed should be true." ”

"San Lang, stop!" The old Wind Demon ninja saw that his brother's technique would not work in the world, so he stopped in time.

"Damn!" Wind Demon Saburo gritted his teeth and took the ninjutsu and looked at the unharmed world on the field. "Who are you?"

"Hoho~!" In order not to trouble the Uchiha clan, the world wears a full-coverage mask in the shape of a scorpion. At this point, there is hardly any part of the world that is exposed. So, with the help of the mask, she changed her voice slightly, and smiled at the Wind Demon Saburo: "What person? The one who killed you, of course! ”

"Humph!" Wind Demon Jiro snorted coldly, looked at the little man in front of him and said, "You guy should be a ninja from another country!" ”

"Huo~! Am I that obvious? "The world doesn't matter.

"We are members of the Wind Demon Clan, one of the two strongest Blood Inheritance Limit Families in the Wind Country, for a novice like you who doesn't know anything, hum~! Often the fastest to die! Wind Demon Jiro said disdainfully.

"Haha! Wind Demons, that's what it looks like! The world pretended to be arrogant and indifferent.

"That's why I hate you the most!" Wind Demon Erlang said to his younger brother beside him: "San Lang, this guy is more flexible, don't use techniques like Sha Shiyu." ”

"Yes! Second brother! Wind Demon Saburo understood, slapped it on the ground, and shouted: "Magnetic Escape - Sand Waterfall Burial." As soon as the words fell, in front of Wind Demon Saburo, endless sand rolled out of the ground and struck the world with a monstrous wave.

"Hmmm! It looks spectacular, but it doesn't work. As the world spoke, a chakra began to condense in the position of the right hand, and this chakra emitted a change in the thunder attribute under the control of the world. Suddenly, thousands of birds sang in unison.

"Chidori!" As the world's body was blessed with the Thunder Attribute Activation Technique, her speed also began to explode at this moment. Under the control of the writing wheel, the world rushed towards the two guys at a speed that was unobservable to the naked eye.

"Hmph~! Under such ninjutsu, no ninja can resist this force. Wind Demon Saburo said confidently.

Wind Demon Erlang frowned and looked at his younger brother, his intuition told him that the other party was not so simple. Sure enough, with a sound similar to the chirping of a thousand birds. His face changed slightly. "It's Thunder!!"

In some ways, the magnetic escape has the weakness of the earth escape, which is restrained by the thunder escape. Therefore, he knew that his younger brother's magnetic escape technique could not be stopped. So, relying on his astonishing reaction speed, at the moment when the world used a thousand birds, he squatted down and slapped his hands on the ground.

“pong~！” With the sound of sand being broken rapidly, the figure of the world appeared in front of them. At this time, as his proud ninjutsu was cracked, Wind Demon Saburo's consciousness was still in shock and did not come back to his senses. However, the world would not wait for him to come to his senses, and the palm of the thunder and lightning stretched out towards the sixteen or seventeen-year-old boy in front of him.

So, at this critical moment, a black metal wall rose from the earth and blocked the world.
