The three imps from Class 7 came to the door simply because they wanted to see Kakashi's true face.

After visiting some of Kakashi's seniors and getting no answers, they set their sights on Ruri.

Except for those old people with serious faces, it is estimated that only Ruri, whose strength is explosive in their opinion, knows what Kakashi looks like.

……

"I'm sorry, I don't know." When Ruri saw Kakashi, Kakashi was already wearing a mask.

No, even if someone has seen Kakashi's face as a child, but after all these years, who still remembers what he was like when he was a child?

"Don't you even know the seniors of Ruri?" Sakura's expression was slightly disappointed.

"I guess Kakashi is too ugly, that's why he wears a mask all the time, so don't ask about it anymore, what if it makes Kakashi sad?"

Ruri naturally flicked Kakashi's pot called Nagaug.

"That's right, if we see it, Kakashi-sensei will be very hurt, too. So let's not dig deeper. Sakura is very reasonable.

"Nani? But I'd love to see what Kakashi-sensei looks like......" Naruto said reluctantly.

Sasuke on the side didn't speak, but looking at his expression, he obviously agreed with Naruto.

"Well, you'll have to find a way to find out the information without attracting the attention of the target, which is also a compulsory course for ninjas...... But if the target is the elite Shinobi Kakashi, you imps won't succeed. ”

"Cut! In that case, then we must succeed in showing you! Naruto was not struck by Ruri's words, but was full of confidence.

"OK, if you have the ability, get the photo back." Ruri didn't continue to say anything, and now they couldn't fight Kakashi's old Yinbi, just calmly threw Naruto a miniature camera.

"This miniature camera is borrowed for you, go ahead and take a picture of Kakashi's true face."

"Yo Si! So let's go! ”

……

"What are they doing here?"

Kenshin, who was returning home from training, saw the three people in the seventh class leaving his house and wondered.

……

"I never thought of it, lalala~"

In the basement, Ruri is looking at the data that Johnson had previously recorded and making some annotations.

Although the body's reaction was recorded together, some details still had to be added to the glass.

"After reversing the Eight Gates, a large number of chakras will be generated, and this chakra will be retained, but at the cost of consuming life force, so it is destined that this technique cannot be used excessively for a long time."

"The Thunder Ninja Technique can greatly strengthen physical fitness, but it requires a lot of training. Therefore, we must find a way to make a chakra that can strengthen the body when you go out on the street, that is, the Yang Dun Chakra......"

"Chakra is fed by life force and mental power to grow, but Yang Dun Chakra can replenish life force, and the consumed life force can also be replenished by eating, so the limitation in the middle is the recovery ability of the body, and the recovery ability of mental power."

"If the chakra transformed by vitality is directly transformed into yang chakra to nourish the body and restore vitality, even if there is some loss in the process, it is not a matter of worry, then the last remaining constraint is the problem of spiritual power......

Drawing in circles, Liuli finally built a circulating system, allowing Chakra to strengthen the body's system.

And in the process, the amount of chakra will also increase steadily, faster than simply feeding the body and mental strength.

"Stimulate the latent vitality of the body, transform it into Yang Dun Chakra, and then use this Yang Dun Chakra to warm the body and build a cycle, and the key to consuming in the middle is spiritual power...... And this kind of cyclical life force consumption supplement method is not too good for the body, that is to say, children can't use it with great intensity? It's perfect for adult beginners. ”

"If this way continues, one day there will be a complicated system, but simply using oneself as a support, there is no direct plundering of the energy of heaven and earth or the feeling of cultivating immortals, that is to say, in the end, do you still have to start with natural energy? No, the way of using natural energy is too wild, which is more suitable for psychic beasts, while the human method is more suitable for the cultivation of magical power...... Demon power, spiritual power, probably so. ”

"In the end, what is cultivated must be a combination of magic and chakra, something called immortal chakra?"

"Well, we're going to have to insert a link into it, and obviously, the spell sigil is the best choice."

The well-established spell sigil system is the easiest, most convenient, and fastest way to obtain mana.

Compared to the natural abilities absorbed by the immortal mode, the magic attached to the spell mark is easier to control and more affinity as a natural energy, and only needs simple control to be able to fuse the chakra to form the so-called fairy chakra.

"But this is not the immortal cultivation I want, people who don't have a curse mark and a chakra seed can't imitate this cultivation method at all...... Well, forget it, let's get this way out first. ”

……

"Johnson, record!"

"The 45th experiment, control the chakra formation cycle."

……

"The 48th experiment, incorporating magic into the chakra cycle."

……

"The 55th experiment, the Immortal Chakra Seal is simplified."

Ruri sat cross-legged, closed her eyes, and began to seal.

Kenshin suddenly walked down from the bottom of the building and shouted through the glass door of the basement, "Dad, Mom, and sister are back, saying that the Hinata patriarch invited us in the evening...... Wow! ”

Kenshin's unfinished words were directly interrupted by an exclamation.

Because in the scattered basement, the figure sitting in the glass is emitting a bright blue light.

A blue air current, wrapped in a strong cold air, was spit out by the glass, forming a crystal blue sphere the size of a walnut in the air.

Powerful chakras and magic fluctuations emanate from it.

That kind of power, like the last time I saw Ruri use the infinite sword system, crushing everything in terms of magnitude.

Liuli's hands were still sealing, and the golden technique kept climbing up the blue sphere floating in front of Liuli.

The clone who was left on the side to prevent accidents made a silent gesture and motioned for him to just look.

Kenshin nodded stunned and looked through the glass door.

……

The golden magic lines flowed out of Liuli's hand in layers, wrapping around the blue sphere.

The aura of the powerful chakra and magic mixture was gradually suppressed, and the fine golden lines crawled all over it.

After a moment, the brilliant blue light finally dimmed, leaving only a sapphire-like sphere, covered with fine golden veins on the outside, which looked unusually gorgeous.

And Ruri finally took a deep breath and swallowed the orb directly into her stomach.
