"How so?"

Kitayama Xu frowned, "Obviously there is no injury, and you also said that although his mental state is turbulent, he is not injured, how can he be unconscious?" ”

"I don't know."

Chiba frowned.

When he arrived at the hospital, after a careful examination, combined with his perceptual investigation, he determined that Kakashi was not injured at the moment, but his mental state was slightly unstable.

This situation is peculiar.

He thought of a possibility.

Could it be ......

The spiritual collision between himself and Kakashi inadvertently activated Kakashi's kaleidoscope writing wheel eye pupil power?

After all, Kakashi's eyes had been opened when he was a child, just like Obito, but he didn't know how to use them himself, so he kept using the three hooks.

Other than that.

According to his own spiritual power cultivation research, the key to the growth of spiritual power is to stimulate-

This stimulus can come from itself or from the outside world.

The Yamanaka clan is the former.

Kakashi is clearly the latter this time.

"If that's the case, Kakashi is pure porcelain this time."

The corners of Chiba's mouth twitched.

But.

The good news is that your own mental power ninjutsu is feasible, and it may be far more effective than expected.

The bad news is –

These few days just happened to be the time to register for the Chunin exam, and if Kakashi didn't wake up tomorrow, he might have to help Kakashi sign up.

It's numb!

It's all about it.

"Kitayama-sensei, you can keep yourself busy, Kakashi-sensei should wake up soon since he is not injured."

"Are you sure?"

Beishan Xu's eyes were full of suspicion, and then he said angrily, "You dare to mess around in the spiritual realm, what if you hurt him?" ”

"Ahem, I know it's wrong."

"If you know it's wrong, you won't try."

Kitayama rolled his eyes.

Last time Chiba sent Kai to the hospital, and this time it was Kakashi's turn.

Next time, it won't be himself or Captain Yamato, right?

Kitayama was trembling.

"Okay, I won't teach you a lesson, I just ask you not to try any tricks in the future, my teacher is different from your others, and I don't need to be beaten."

“……”

Chiba stared blankly, speechless.

I don't hit the teacher again, and this time it must be a misunderstanding!

Kitayama ran away.

Chiba sat in the hospital room and took out a pen and paper to summarize.

Because it was the first test, he didn't dare to use too much force, and he restrained most of his mental power, which was still different from actual combat.

But it has reached the standard of actual combat, and further attempts can be made in actual combat in the future.

It's respiratory activity.

Kakashi only created the most rudimentary jutsu, and the effect may not even reach the first activation of Shiro, and the effect is only comparable to the stimulating activity of the Thunder Chakra.

"Increase oxygen capacity."

"If you don't have a certain amount of exercise, you may not be able to do it."

Chiba frowned.

The next moment, he tried to extract the chakra and condense it into his lungs.

Subsequently—

The cells around the lungs are the first to be activated.

In a few breaths, Chiba felt his own blood quickly transfused throughout his body, and in the blink of an eye, the cells in his whole body entered a state of activation.

"If I don't cooperate with the limit state, I should only have the strength of the first activity, but if I cooperate with the limit state, my strength and speed should reach the strength of the second activity."

Chiba heart estimate.

But.

His current lung capacity is at most twice as high as usual.

If it is raised to four or five times, I am afraid that the body will show other changes, but how to achieve this remains to be considered.

Chiba writes and draws on paper, and after a minute or two, the figure leaps onto the paper.

Mouth, nose, lungs.

What else can you breathe?

Skin!

Chiba writes underneath.

The skin is breathable –

Even though it breathes less than one percent of the lungs, it blesses the chakra and stimulates the activity, which can provide some oxygen intake.

Other than that.

Something suddenly occurred to him.

In terms of breathing, who can compare to the Autumn Dao family after doubling, Violet only created the third activity on its own, which is limited by the problem of lung capacity and oxygen content.

After the Akido clan was multiplied, they didn't have to worry about lung capacity at all.

"Feasible."

Chiba muttered to herself.

The versatility of this technique is very strong.,Shadow level to lower ninja.,As long as you can learn it, you can use it.,Not limited by the category that ninjas are good at.。

The lower limit of the mass insurance, the upper limit of the autumn road home insurance.

It reinforces that feedback must be very powerful!

He quickly jotted down his speculations and conjectures about the follow-up in his notebook.

The first activity has been resolved.

The second activity, adding the overrun state, increases the amount of oxygen on the basis of the first activity.

Third, the activity has been further strengthened......

As for further up, it may depend on the oxygen content, if you can use special air with a relatively high oxygen content, maybe ordinary people also have a chance.

Otherwise, only the Autumn Dao clan can master it.

Of course.

There is a hidden concern here, that is, oxygen poisoning, so there is a difference between the seven-day call method and the eight-door Dunjia-

Eight doors Dunjia can directly open six doors, but seven days of calling the law may not work.

The third activity should be the limit of direct on.

If you don't let the body gradually adapt to high oxygen and directly turn on the third activity or above, I am afraid that you will fall into oxygen poisoning and even lung failure.

Thinking of this, Chiba stopped his pen and looked at it carefully.

All that's left is experimentation.

It's a pity that Kakashi hasn't woken up yet, otherwise he would have gone to Dingza for an experiment now.

He had nothing to do on the sidelines, so he simply began to think about another idea-

Based on the idea of chakra membrane, the inner and outer chakra cycle is derived.

In its normal state, unless you can fuse it with Chakra Absorption, it is meaningless.

However, if it is in the immortal mode, it may be possible to achieve internal and external circulation and continue to absorb natural energy.

Even if the recovery speed can't keep up with the cost, it can definitely extend its duration.

But.

In that case, the details of the technique still need to be optimized, since you are in a combat state, you don't need to isolate the breath and block the perception, you can focus on gathering natural energy.

Although it is not in the immortal mode, it is completely possible to try in advance by gathering and absorbing internal and external circulation.

All afternoon, Chiba pondered this thing.

Wait for Kakashi to wake up......

He saw Chiba pacing on the side, the chakra aura on his body never stopped, and after using his perception ability, Kakashi became more and more shocked-

The natural energy around Chiba is very active, as long as you know how to perceive the natural energy, you can sense it with a little meditation.

Not only that, the layer of chakra on Chiba's body seems to be continuously absorbing the natural energy of the outside world, forming an internal and external cycle with the internal chakra.

Kakashi quickly understood the significance of the study.

Maintaining the chakra layer will deplete the chakra.

But.

It is exchanged for natural energy, immortal chakra.

What the heck?

Have I been in a coma for many days?

Kakashi was at a loss.

"Kakashi-sensei, are you awake? How's it going, are you feeling better? ”

"There's no problem, in fact, your attack is well controlled, it didn't hurt me much, I was unconscious and seemed to have been countered by using too much pupil power."

Kakashi covered his eyes and couldn't help but sigh, "It's not the Uchiha clan, and getting the Sharingan isn't necessarily a good thing. ”

Chiba pondered for a moment.

Kakashi still didn't realize the mystery of the kaleidoscope, thinking that he was a non-Uchiha and unconscious caused by his eyes not harmonizing.

How do you remind you?

He thought about it again and again, but did not say the "kaleidoscope" conjecture at this moment.

If you say it now, it's too targeted.

"So we're out of the hospital now?"

"Well, by the way, how much did it cost?"

"I'm a member of the medical class, it doesn't cost much to go inside, let's go, I invite you to dinner to apologize."

Chiba didn't answer directly.

He couldn't afford this amount of money, and although Kakashi was not the main cause of his coma, his mental stimulation was the trigger.

And.

He also had some questions that he wanted to ask Kakashi, such as ......

Thunder Armor.

Kakashi looked at it with a blank eye, feeling that something was wrong, and after thinking about it, he didn't mention the money, but quietly left the hospital with Chiba.

I followed all the way to the outside of the barbecue restaurant's box.

Kakashi couldn't help but gasp.

"Chiba."

"Huh? Kakashi-sensei, go in and sit. ”

"No, I want to ask first, do you have any questions? If so, ask me before deciding if you want to eat the meal. ”

Kakashi's face was solemn.

"I have a question for you, but it's definitely not dangerous...... Well, I'd like to ask you about the Thunder Escape Armor, I want to create a defensive ninjutsu in Chakra mode. ”

As for being so scared?

Chiba was speechless.

When Kakashi heard this, he breathed a sigh of relief.

This meal......

It seems to be edible.

He walked in and sat down, and Chiba took the waiter's menu and ordered it.

When the waiter left, he arranged an enchantment technique to block out the sound, and then said, "Kakashi-sensei, have you ever copied the Thunder Escape Armor?" ”

"I've seen it, but I haven't learned it."

Then, Kakashi said the reason-

The Thunder Dun Armor needs to maintain the Thunder Chakra to keep the whole body in an active state, and then cooperate with the physical technique and high-density Chakra to achieve a defensive effect.

The reason why he won't be is simple and crude.

Chakra is not enough!

"With that chakra, I can kill several with Rachel and speed, so I've never tried it."

"Can you tell me how it works with the physical arts?"

"Of course."

Kakashi thought for a moment, and somewhat understood Chiba's thoughts, "Replace the Thunder Chakra Stimulating Activity with Respiratory Activity?" It's doable, but ordinary chakras can't be as close inside and out as thunder chakras. ”

"I also have the Chakra Shield, which replaces the effect of the Thunder Chakra with internal and external circulation."

Chiba explained.

Kakashi pondered for a few seconds.

The chakra shield should be the same as before.

Well......

This can be tried, and if it can be successful, it can indeed improve its defense ability.

He pulled out "Intimate Violence".

"When I'm done eating, I'll go back and write it out, are you free tomorrow?"

"Yes, I'll stay in the village tonight."

I'll have to go to Dingza tomorrow morning, so Chiba won't be back to the institute tonight.

Kakashi nodded.

"Then I'll go back and practice, sort it out, and I'll give it to you tomorrow, and by the way, I'll talk to you about respiratory activity and your current technique."

"No problem."
