Konoha's Hextech Ninja

"You're really good, Kurenai." Yagami Yoruichi smiled and rubbed Kurenai Yuhi's little head.

There's nothing to brag about in terms of grades at the ninja academy, but seeing Kurenai Yuhi so happy makes Yoruichi Yagami happy too.

Seeing the girl she raised with her own hands become more and more outstanding is something that Yagami Yoruichi finds very fulfilling.

"Yoruichi-kun, you have to train with me again today!" Kurenai Yuhi grabbed Yoruichi Yagami's arm and said coquettishly, "You promised to teach me ninjutsu at the end of this semester."

"Alright, alright." Faced with Kurenai's coquettishness, Yoruichi Yagami couldn't refuse at all and could only say, "I'll teach you today! But let's eat first."

As she spoke, Yagami Yoruichi pulled Kurenai Yuhi into the house, then turned to Kaori Uzumaki, who had been standing quietly to the side, and called out, "Kaori, come in and have dinner with us."

"Yes, Yoruichi-sama." Kaori Uzumaki bowed respectfully before saying, "Yoruichi-sama, I also got first place in today's practical test."

"Oh, right." Kurenai seemed to have thought of something and said, "Our exams ended early, and I went to watch Kaori's exam. Her ninjutsu is amazing; none of the other students could stop her."

Kaori Uzumaki taking first place was not surprising to Yoruichi Yagami.

After all, she was only a first-grader, and there weren't any famous geniuses in her grade.

With Kaori Uzumaki's chakra approaching Kage level, even if her control over ninjutsu is slightly lacking, as long as she can utilize it effectively, she can deliver a devastating blow to her classmates.

However, since he performed well, he should still be praised. Yagami Yoruichi nodded and said, "You performed well."

"It's all thanks to Yoruichi-sama's excellent teaching," Kaori Uzumaki said earnestly.

Kurenai glanced at Yoruichi Yagami, then at the serious-looking Kaori Uzumaki, and suddenly burst into laughter, as if she had thought of something.

When they first met, Kurenai Yuhi was full of hostility towards Kaori Uzumaki.

But after spending some time together, Yuhi Kurenai and she became very good friends.

Yagami Yoruichi glanced at Kurenai Yuhi, and for some reason, she suddenly laughed.

However, he didn't mind and invited the two girls inside to eat.

“Red, your attribute is very special. Your innate attribute is only Yin Release.” Yagami Yoruichi said, “Logically speaking, only Yin Release techniques are suitable for you. However, the most common Yin Release technique is Genjutsu. Apart from Genjutsu, there are only some secret techniques that even I don’t know.”

For example, the shadow techniques of the Nara clan and the mental techniques of the Yamanaka clan both fall under the category of Yin Release.

However, these esoteric families are extremely strict in guarding their family's secrets.

If Yagami Yoruichi wanted it, given her status and strength, the Nara and Yamanaka clans wouldn't be so tactless as to refuse.

But it's unnecessary.

While both of these techniques are quite effective, they also have obvious drawbacks and are not suitable for Kurenai Yuhi.

Yagami Yoruichi changed the subject, saying, "However, besides basic ninjutsu, there is also a type of ninjutsu that has no attribute, meaning that people with any attribute can learn it."

For example, the most basic Three Body Technique is a non-elemental ninjutsu, as is the Shadow Clone Technique.

Or some special forbidden techniques, such as the Impure Earth Reincarnation, also have no attribute restrictions.

However, when it comes to practical value, the Rasengan is undoubtedly the most famous.

Kurenai Yuhi's illusion magic is a type of mid-to-long-range combat, but it is a weakness in close combat.

Therefore, Yagami Yoruichi plans to teach her the Rasengan to make up for her lack of skill in this area.

If an enemy gets close, a single Rasengan might just change the course of the battle.

As for whether Kurenai Yuhi can learn this ninjutsu, Yoruichi Yagami has no doubt.

Developing the Rasengan is difficult, but mastering it simply requires a high level of control over chakra.

As long as your chakra control is up to par, training is quite easy.

It just takes a little more time.

Naruto Uzumaki can learn the Rasengan in a few days.

Even if Kurenai Yuhi's talent is lacking, she can learn it in one or two years, or even three or five years if necessary.

"The technique I'm going to teach you is called Rasengan. You've seen me use it before," Yagami Yoruichi reminded her. "It's the ninjutsu I mastered when I was training with Kakashi and Inahisa. It's a ninjutsu without any elemental attribute."

"Rasengan?" Kurenai Yuhi remembered the ninjutsu that Yoruichi Yagami used to frequently use, and nodded vigorously, saying, "I want to learn that!"

The thought of being able to use the same ninjutsu as Yoruichi Yagami filled Kurenai with joy, and she couldn't wait to learn the Rasengan.

"No rush, let's eat first." Yagami Yoruichi said with a smile, "The Rasengan requires a high level of chakra manipulation and control. Your current chakra control is not good enough, so it will probably take a long time to master it. Don't worry, I will teach you how to improve your chakra control."

Chapter 207 Chakra Technology Breakthrough! The Chakra Cannon of Kumogakure?

The year is now Konoha 44.

But this New Year was not as grand and noisy as in previous years.

The war is not over yet.

Although the main force at the front was the four major ninja clans of Sarutobi, Shimura, Mitomon, and Utatane, other ninja clans and civilian ninjas also contributed a portion of their forces.

The shadow of war loomed large, and the villagers of Konoha felt more or less worried.

Of course, the ninjas who actually had access to high-level information didn't feel particularly nervous.

The reason why the war with Kumogakure was at a stalemate was that the village deliberately sent the four great ninja clans to their deaths.

The clans to which the Konoha F4 belong have thousands of unregistered ninjas, almost equal to the total number of all registered ninjas in Konoha.

Although every ninja clan has some members who have the ability to become ninjas but do not register in the village and only obey the clan's orders.

However, the four major families, including Sarutobi, went too far.

The Konoha leadership will not allow the war to end until their numbers have dwindled to a certain level, nor will they send any additional reinforcements.

Even if the four great clans were truly capable of defeating Kumogakure, Konoha would choose to open a new battlefield to deplete the strength of the Sarutobi clans.

However, in the eyes of most ordinary villagers who did not know the truth, it was simply that the Hidden Cloud Village was too strong and could fight Konoha to a standstill.

In addition, some Konoha ninjas sacrificed their lives in previous wars.

Throughout the New Year, the atmosphere inside Konoha was subtly oppressive.

However, not long after the New Year, good news soon arrived.

……

Inside the laboratory of the Science Department.

Yagami Yoruichi looked at the enormous device in front of her.

Despite not understanding the principles and structure, Yagami Yoruichi quickly grasped the purpose of this thing that looked like a giant iron can after Orochimaru's explanation.

They absorb and store chakra, and convert it into common energy types such as electricity and heat.

"This device can store a huge amount of chakra. If it were all converted into electricity, assuming every household in Konoha used electric lights and kept them on all day, it would be enough to support the entire village's electricity consumption for a year."

Orochimaru explained.

The technology tree in the ninja world is crooked.

But at this point in time, there are very few types of electrical appliances.

For ordinary people, even electric lights are rare items, and other electrical appliances are even more difficult to come into contact with.

While some of these cases involve ordinary people being too poor, the main reason is that infrastructure development is inadequate.

You can't build a small power plant just to supply electricity for one family, can you?

Without the ability to transmit power over long distances, the economies of scale of large power plants cannot be realized, leading to high power generation costs.

Even in ordinary towns, it is very difficult to see electrical appliances. Only some wealthy nobles use things like large storage batteries to power their home appliances. Ordinary people simply cannot afford them.

According to the investigation conducted by the Anbu at Yagami Yoruichi's request, only five large cities in the entire Land of Fire have the necessary power infrastructure and electricity. Konoha is one of them.

However, although the Land of Fire is rich in resources, its coal reserves are not high, and it mainly relies on imports from the Land of Earth, making power generation extremely expensive.

If an average family installs light bulbs in their home and turns them on for a few hours every night, their monthly electricity bill could reach thousands of taels.

Ordinary families simply cannot afford such expenses, unless there is a ninja of Chunin level or above in the family and the family has a relatively high income, then they are willing to install it.

Yoruichi Yagami immediately asked the question she was most concerned about: "What is the cost of converting chakra into electrical energy?"

"That depends on how you calculate the cost," Orochimaru chuckled. "To fully fill this thing with chakra, it would probably be able to drain all of the Nine-Tails' chakra. If it were an ordinary ninja, Yoruichi-kun, you could probably fill it up after using up your chakra a few times."

How many times does it take to fully replenish one's chakra?

Yagami Yoruichi was momentarily speechless.

However, upon further reflection on Orochimaru's words, Yagami Yoruichi suddenly felt that they were a bit outrageous.

It takes several uses of chakra to fully recharge, while the Nine-Tails only needs one?

Doesn't that mean that, in terms of chakra quantity alone, Kurama has definitely reached the 'Six Paths level', and even among the Six Paths level, it has a relatively large amount of chakra?

However, upon closer reflection, it's not surprising.

When the Sage of Six Paths divided the Ten-Tails to create the Nine-Tailed Beasts, he clearly favored the Nine-Tails, giving it the vast majority of the Ten-Tails' chakra.

The combined chakra of all the other tailed beasts probably doesn't even equal that of the Nine-Tails.

As for the Ten-Tails, in terms of chakra quantity alone, it is much stronger than many Otsutsuki, and may even be close to or have broken the chakra limit of the Six Paths level.

“However, it’s not realistic to expect ordinary ninjas to charge it up.” Yagami Yoruichi said with some hesitation, “We have to rely on ninjas with large amounts of chakra, or even Jinchuriki, to charge it up.”

“It’s perfectly fine for ordinary ninjas to recharge in batches, it just takes time to recover after the chakra is depleted.” Orochimaru pointed to a display screen on the large iron can and said, “I set a scale here, with the unit being one millionth of the total chakra it can store. An ordinary genin can provide at least a few units of energy.”

When Yagami Yoruichi saw the logo on the screen, it read 1421/1000000.

It is clear that Orochimaru had stored a portion of his chakra in advance in order to test its effectiveness.

He might even be using his own chakra.

"How do I charge it?" Yagami Yoruichi asked.

"Use this." Orochimaru took out something that looked like a glove, with a cord with a plug on it.

Orochimaru inserted the plug into the socket at the bottom of the large iron can, handed the glove to Yoruichi Yagami, and said, "Just input the chakra through your hand. It doesn't matter if you're fast. I've specifically enhanced its stability, so it can safely receive even the chakra bursts from S-rank ninjutsu."

Yagami Yoruichi nodded, put on gloves, and channeled chakra.

The numbers on the screen jumped rapidly and soon broke through 10,000.

Yagami Yoruichi only tried it once, without inputting too much chakra at once.

After calculating in his mind, he immediately came up with a rough number.

It would take approximately two million points of chakra to fill it.

In other words, one mark represents two points of chakra (system standard). Even a genin with the weakest chakra can provide five marks of energy at once.

"Could we change this scale?" Yagami Yoruichi asked. "Let's double the value. Let's take the weakest genin who can provide ten scale points at a time as the standard, which means the total scale will be increased to two million."

The standard and system chakra values ​​are the same, which also makes it convenient for Yoruichi Yagami to refer to.

Orochimaru was somewhat puzzled by Yagami Yoruichi's request, but he didn't ask any further questions. He simply said, "That's easy. Just adjust the parameters a little."

Yoruichi Yagami asked a few more questions, and after converting the power consumption, she came to a general conclusion.

A little chakra can probably be converted into nearly 100 kilovolts.

However, considering the inevitable losses during transmission, once it reaches the point of use, a small amount of chakra can only be converted into a few tens of kilowatt-hours of electricity.

Even so, the efficiency is still very high.

The Land of Fire now mainly relies on thermal power generation. Yagami Yoruichi specifically researched the costs involved, finding that each kilowatt-hour costs a little over five ounces.

When sold to consumers, the price varies from a few dozen to several hundred taels per kilowatt-hour, depending on how it is used.

However, if the power were generated using a chakra conversion container, a single genin could provide several hundred kilometers of electricity at a time, so even when assigning missions, the reward couldn't be set too high.

After all, chakra is a renewable resource; it can be fully restored after a big meal and a period of rest.

Based on the recovery efficiency of genin, the 'purchase price' of each point of chakra can be set at around tens to hundreds of taels, which is a little over one tael of electricity per kilowatt-hour.

There is no need to worry about the sales of the electricity produced.

With electricity prices reduced to a fraction of what they could be, or even lower, there are plenty of families in the Land of Fire who can afford it.

Yoruichi Yagami asked a few more questions to confirm that the idea was feasible. She immediately decided to bring it up at the high-level meeting and promote the chakra electricity system to all parts of the Land of Fire, earning the difference in electricity prices by selling the chakra of Konoha ninjas.

"I didn't expect this to be the first project we finished," Yagami Yoruichi exclaimed. "I thought you would put more effort into the Wood Release experiments first."

“I am indeed mainly researching Wood Release.” Orochimaru glanced at Yoruichi Yagami and said, “Yoruichi-kun, didn’t you see the report I submitted? The core technology of chakra energy conversion comes from data in the Third Raikage’s brain.”

The body of the Third Raikage was an important 'trophy' for Konoha Village, and it had long been sent to the intelligence team to decipher the information in his memories.
