If you learn mathematics, physics and chemistry well, you will be able to travel all over the ninja

"Hey~!"

The flying eagle hovering in the sky let out a cry that pierced the sky.

On the top of the rocky cliff in the barren mountain, Xiaotiaoyu was wearing a tight-fitting ninja uniform after a long absence in the summer. He was standing on the edge of the cliff with his hands on his hips, seeming to be admiring the beautiful scenery.

This is a barren mountain, desolate and uninhabited. It is full of barren yellow land and dark brown rocks. It is difficult to find any green skin grafts. The breeze will occasionally blow up a burst of yellow dust.

"Good place!"

Xiaoniao Youxia smiled with satisfaction, and then jumped straight off the cliff.

Huhuhu~

With the wind whistling from his ears, Xiao Niao Youxia closed his eyes and spread his hands, as if taking a leap of faith.

However, she is not an all-or-nothing killer.

Closing your eyes is for better, calmer calculations of sensing wind and regulating chakra.

From the outside, it looks like nothing is going on during the summer.

However, if there is a person with the ability to see the flow of chakra such as Sharingan or Byakugan at this moment, he can find it.

Xiaotiaoyou is constantly releasing chakra in summer. The release of chakra either creates a tension plane to increase wind resistance, or activates small wind escape to decelerate the opponent.

When Xiaoniao Youxia landed in the air about ten meters above the ground, she immediately released the spell, made a light back turn and landed on her feet.

After doing all this, Xiaoniao Youxia slowly opened his eyes. After looking at the desolate area around him, he nodded with satisfaction.

"Well, what a great place. It would be great if there was such a hidden experimental site next door to Konoha."

The series of maneuvers performed during the high-altitude landing just now can actually show how outrageous Xiao Niao Yu Xia's chakra control ability is now.

To be able to reach this level, in fact, it must have been practiced during the period when Kotori Yu was trapped in the consciousness space during the summer, and he practiced and experimented various ninjutsu crazily.

With her current chakra control ability, she can condense a considerable amount of chakra into one point the moment she punches the opponent, and then release it instantly when her fist touches the opponent!

With one punch, the force spreads to the sky.

The destructive power can be said to be very terrifying. In fact, this is also the principle of Tsunade's strange power fist.

As long as the chakra control ability is in place, the strange power punch is indeed not difficult.

However, there are indeed very few people whose chakra control ability reaches the standard of being able to use strange power punches.

This requires considerable talent, and generally ninjas with less chakra have relatively strong chakra control abilities.

Yes, the amount of chakra in Kotori Summer itself is very small.

After all, she is considered a commoner without blood. Her talent as a ninja is already very good, but it is simply impossible to have an explosive amount of chakra.

Therefore, she prepared several plans to increase her chakra energy reserves.

However, now is not the time to experiment with these options.

"Now we are mainly verifying several ninjutsu that have been successfully simulated in the consciousness space."

Xiaotiao Yuxia immediately closed his eyes, formed a sea seal with his hands, and simulated the chakra circuit in his body to start constructing the route of the technique.

Three seconds later, the little bird Yu Xia suddenly shouted: "Ninjutsu! Summon thunder!"

It's sizzling!

Thunder arcs began to form violently around Xiao Niaoyou Xia, until a thunder and lightning dharma circle formed behind his back!

The small stones and dust around him began to stir in defiance of gravity.

However, before Xiaoniao Youxia could make the next move, the thunder and lightning dharma ring behind him suddenly flashed twice and then dimmed and disappeared...

And Xiaotiao Yuxia was discouraged for a moment, her face fell down, and she was a little unhappy: "It's rare that I created such a handsome and powerful ninjutsu! I can't even complete the prelude! How can I practice it!"

"Then the [Force Field Protection], [Electromagnetic Gun], [Laser] and [Nano Cutting Line] are all out of the question?"

Although Kotori Yuxia said so, she actually knew that these ninjutsu were naturally impossible for her to use at this stage.

Now, I just want to test how far I can do it.

To really take off, you must find a chakra supply of energy.

In the past, Kotori Yuxia immediately thought of tailed beasts, but after thinking about the disadvantages of tailed beasts as energy sources, she gave up.

However, she thought of another solution, which was the ubiquitous "natural energy".

It is assumed that the bird can use magic to extract "natural energy" at will and preserve and utilize it.

Then the problem of "insufficient chakra energy" can naturally be solved very well.

Thinking about it, Xiaoniao Youxia continued to form a sea seal, and arcs of electricity wrapped around him again.

In order to sense the existence of "natural energy", she had already made preparations.

One is the ultimate chakra micro-perception, which is a method of using chakra to form a lens of consciousness to amplify one's spiritual perception ability.

And the other one is the electric arc emitted by the little bird Xia Xia, which uses electricity to generate magnetism.

This will allow the bird to form a micro electromagnetic field around itself to capture some of the surrounding energy amplitude.

However, time passed by every minute and every second.

Xiao Niao You Xia maintains two kinds of spells, which can be said to maintain both physical and mental torture, but still no phenomenon can be found.

It wasn't until the sun set in the west and Xiaoniaoyou had exhausted all her summer energy, and she was so tired that she was dripping with sweat, that she decided to call it a day and go home.

In the next few days in the capital of the Country of Fire, except for inspecting new stores and teaching newly acquired personal maids, Xiaotiaoyu will come to the wilderness here in the summer to practice the practice of sensing "natural energy".

Until five days later, when the caravan was preparing to return to Konoha, there was still no big harvest in the summer.

This can't help but make Xiaoniaoyou Xia have self-doubt. Does "natural energy" require specific organs and bloodlines?

Or is “natural energy” actually solar energy?

However, these statements are obviously untenable and obviously cannot be so outrageous.

However, summer bird tours are not without success.

Currently, she has successfully tested two ninjutsu with practical value.

One is Chakra Nano Thread, inspired by the Chakra Puppet Control Technique - Chakra Thread.

However, when Xiaoniaoyu maintains the chakra line to about 100 nanometers, the structure becomes difficult to stabilize.

Through continuous chakra output, the limit can only extend the silk thread to about one hundred meters.

When it can maintain a relatively stable state, it is roughly only within a range of fifty meters.

In the summer of Xiaoniaoyu, you can use the almost invisible chakra nano silk thread and the change of wind escape chakra to enhance its strength while ensuring strong cutting performance!

It can be said that Chakra Nano Thread is a real means of killing people invisible.

As for the other technique, it is high-energy infrasonic resonance!

Unfortunately, although this technique is very lethal, it kills indiscriminately.

Yes, at present, Xiaoniaoyou has no means of protection in summer.

Once used, you must ensure that you are in a safe atmosphere and space.
