The Kingdom of Rain, the City of Six Paths.

Chakra Technology Research Institute.

Many ninjas wearing Ninja uniforms looked nervously at Nagato standing on the test stand.

Nagato, on the other hand, was concentrating on mobilizing chakra and releasing water release ninjutsu on the scroll in front of him.

"Water Release: Water Dragon Bullet Technique!"

Nagato quickly formed a seal and quickly formed a water dragon that rushed towards the scroll.

The scroll on the stage seems to be connected to some infinite space.

Even if it was a large water dragon that could send an adult flying, the moment it touched the scroll, it quickly disappeared from everyone's sight without making the scroll shake at all.

"Is this improvement successful?" Yahiko asked excitedly.

"Should?" Kakuzu is not sure, sealing technique is not something he is good at.

"One time can't explain anything. Let's look at the next test." Mu Yue replied.

He improved the sealing technique used in ninjutsu scrolls, making it easier to make ninjutsu scrolls and allowing more ninjutsu to be stored.

Then Nagato tried several more times, but still succeeded.

"We succeeded!" The Ninja of the Ninja Sect couldn't help but cheer.

According to the success rate of the improved Ninjutsu scrolls, most ninjas in the Ninja Sect will have the opportunity to be equipped with Ninjutsu scrolls, which is equivalent to mastering an additional batch of Ninjutsu out of thin air, and using them does not require much chakra consumption.

"If the scroll is obtained by other ninja villages, will they be able to copy it?" Kakuzu looked at Soyousuke and asked.

If other ninja villages do not have the ability to imitate, the Ninja Sect can make a fortune relying on the new ninjutsu scrolls.

The new ninjutsu scrolls of the ninja sect are much stronger than the old ninjutsu scrolls that have not been improved.

The first is the difference in production difficulty. Old-tech ninjutsu scrolls have high requirements for making ninjas. They are also more difficult and prone to failure, and the overall cost is high.

If the Ninja Sect is willing to engage in a price war, feel free to kill the old Ninjutsu scrolls.

Once again, the upper limit of ninjutsu scrolls has been greatly increased.

Currently, most of the ninjutsu scrolls on the market in the ninja world are water release ninjutsu scrolls.

It's not that the scroll can't seal other ninjutsu, but the sealing technique on the old ninjutsu scroll is not very useful for storing energy like thunder and fire.

It's like putting a huge fire ball into an old-tech ninjutsu scroll.

When the ninja uses it, it will not be a fireball hitting the opponent, but a pile of flames will burst out with the scroll as the center.

It's not that it can't be used, but it's not easy to use. It's better to use the detonating charm directly, and it's cheaper.

The Ninja Sect's new ninjutsu scrolls do not have this problem. There is not much difference between releasing ninjutsu and releasing ninja seals.

"If it's Konoha, it's possible to crack the technology." Mu Yue thought for a while and said.

His sealing technique is essentially the same as the Uzumaki sealing technique. If Konoha gathers Kushina and other sealing masters together to study it, it will only be a matter of time before it is cracked.

After all, it is easier to research and crack the technology in front of your eyes than to develop it.

His sealing skills were higher, but not so high that Kushina couldn't understand.

"That's right, then we have to keep it confidential." Kakuzu nodded.

Even if only Konoha could crack it, he would not sell it to other ninjas.

Based on Kakuzu's understanding of those ninja villages, if the Ninja Sect really has a chance to become the sixth largest ninja force, there will definitely be more than one or two enemies.

"It needs to be kept secret, but it can also be sold to a certain extent, whether it is to a daimyo or a ninja village." Mu Yue shook her head.

"Even Konoha won't be able to crack the technology in the short term. By the time they crack it, we will have developed better technology."

Mu Yue is not afraid that his sealing technique will be cracked, because he has a stronger version.

If you have the opportunity to make big money, you must make it, otherwise how can you make the five major ninja villages jealous and make them increase their investment in technology.

It's just that this little achievement can't catch Mu Yue's eyes. What he wants is real chakra technology.

Combining chakra with technology can greatly enhance the overall strength of the ninja world while developing productivity.

"That's it, then you can make a lot of money." Hearing Mu Yue's words, Jiaodu's eyes lit up.

Selling to daimyo is indeed a very good choice. Those daimyo are rich enough and their ninjas are not strong enough, so they will definitely be happy to buy their new ninjutsu scrolls at a high price.

Due to the shortage of ninjas in the ninja sect, Mu Yue directly mobilized a large number of rain ninjas to Liudao City to make ninjutsu scrolls.

In addition, for convenience and because the timing was almost the same, Mu Yue asked the Yu Ninja Village to announce the identity of his Yu Ninja leader.

The Great Ninja Village, which had conducted detailed investigations into the Ninja Sect, had long known that Sosuke secretly controlled the Rain Ninja Village, but some small forces did not know this and were shocked.

With the ninja power of the Rain Ninja Village as a supplement, the problem of the number of ninjas in the Ninja Sect was instantly solved. In terms of strength and scale of power, it is the undisputed number one among the five major ninja villages.

Coupled with the newly developed ninjutsu scrolls by the ninja sect, various news about the ninja sect swept the ninja world, and villages in various countries were discussing the ninja sect.

Some people discuss the power of the ninja sect, while others discuss the techniques of the ninja sect.

Riding on this craze, the Ninja Sect continued to expand the Six Paths Castle, absorbing ninjas who agreed with the Ninja Sect's philosophy, and continued to strengthen itself.

While developing itself, the Ninja Sect was also giving back to the Country of Rain. Driven by the Six Paths Castle, the economy of the eastern part of the Country of Rain developed rapidly.

In addition, the Kingdom of Birds, which has a branch of the Ninja Sect, has also reaped the dividends from the development of the Ninja Sect and gained some development opportunities.

Seeing the Ninja Sect making a lot of money and growing rapidly, the great Ninja villagers were anxious.

The three major ninja villages of Iwagakure, Cloudgakure and Sunagakure quickly cooperated and established relevant research laboratories, gathering the elites of their own villages to crack the new ninjutsu scroll technology and introduce new ones.

Since the technology was more critical this time, they increased their cooperation, and the originally shaky alliance became solid and tight again.

Even Mito Monohan and Koharu Koharu couldn't sit still and strongly supported the research of ninjutsu scrolls at the high-level meeting.

Sarutobi Hiruzen even proposed to invest more funds in other research, so that the Ninja Sect cannot always maintain its leading position.

Mu Yue was happy to see this result, so she passed everything.

After the meeting, Namikaze Minato followed Muzuki back to the Hokage's office.

"I'm sorry Muyue, I can't help you share the pressure during such a critical period." Namikaze Minato said to Muyue with an apologetic look.

Because he had to take care of the pregnant Kushina, Minato Namikaze didn't work overtime and got off work on time.

It was fine when he was free, and he could finish his affairs, but now that Konoha was busier, Namikaze Minato felt a little embarrassed.

"There is no need to say such things. Kushina's pregnancy is not only important to you, but also to the village. It's okay for you to worry." Mu Yue shook her head slightly.

Pregnancy is a very important thing, especially for jinchuriki.

Because during pregnancy, the energy in the ninja's body will automatically be used to nurture the fetus, which will cause the seal to weaken, and the tailed beast will most likely take the opportunity to break the seal and escape.

Hearing Mu Yue say this, Namikaze Minato felt a little more relaxed.

"Recently, Fugaku's second son has been born safely. I hope Kushina will also go well." The two families have a good relationship. In addition to Namikaze Minato and Uchiha Fugaku, Kushina and Uchiha Mikoto are also friends.

.

"It will go smoothly," Mu Yue said.

Obito did not turn black, and Uchiha Madara was killed by him, leaving only Black Zetsu with no reason or ability to come to Konoha to recreate the Night of the Nine-Tails.

"Well, when the child is born, Muyue, you should come to visit us more often, lest the child mistakes us." Namikaze Minato joked.

Mu Yue thought for a while, if it was Naruto, she really couldn't tell.

Naruto in the parallel world has already admitted his mistake once.

…

After dinner, Shisui went to the small park in the Uchiha clan.

He and Itachi had an agreement to meet once a week on Sundays when nothing happened, chatting together or Shisui telling Uchiha Itachi stories.

If something happens, Shisui will inform Uchiha Itachi in advance that he doesn't have to go.

"Itachi, good evening." Shisui smiled and greeted Uchiha Itachi who came over.

After saying hello, Shisui and Uchiha Itachi sat on the park bench together.

Just when Shisui wanted to say something, Uchiha Itachi suddenly stood up, looked at Shisui seriously and said:

"Brother Zhisui, please teach me how to practice as a ninja."

Shisui looked at Uchiha Itachi with some surprise, "Why do you suddenly want to learn ninja knowledge from me? At your age, you should have been taught a little bit."

Unlike ordinary people, the ninja clan has preschool education within the clan, and you can be exposed to a lot of ninja knowledge before going to ninja school.

"Because I want to become stronger and protect my brother." Uchiha Itachi answered honestly.

The moment he called his younger brother's name for the first time, Uchiha Itachi felt a special feeling that the five-year-old him could not express. It was a different emotion from his parents.

Uchiha Itachi didn't know how to describe it, but looking at his newborn brother who was as fragile as a dream, he truly felt a sense of responsibility to protect him.

Although he was only five years old, both Uchiha Fugaku and Shisui had told him about the cruelty of ninjas.

This ninja world is very dangerous. If you want to survive and protect the people you want to protect, you need strong strength.

And Shisui is the best being Uchiha Itachi knows so far.
