For Uzumaki Naruto, this period of time at the Giant Turtle Island Base was really unbearable. Fortunately, what he was doing now was the practice that he was most willing to do. As long as he could improve his strength and get closer to his dream of becoming a Hokage and being recognized, he would persist even if it was something he didn't want to do.
For Uzumaki Naruto, practicing chakra control, which he was not good at, and controlling the extremely difficult Nine-Tails Chakra, was simply torture.
The most unruly chakra meets Uzumaki Naruto who is not very good at chakra control. This combination is really embarrassing.
The Uzumaki family is proficient in sealing techniques, so they should be quite talented in chakra control.
Unfortunately, Uzumaki Naruto perfectly avoided the bloodline advantage of the Uzumaki family of his parents Kushina Uzumaki. Although his chakra control ability is slightly stronger than that of untalented ninjas, he has no advantage over those with slightly qualified talents.
He did not inherit any of his father Minato Namikaze's control ability, nor the level of sealing technique that allowed him to control the Flying Thunder God Jutsu.
The only comforting thing is that Uzumaki Kushina's violent temper and impatient character were inherited perfectly, and Namikaze Minato's sunny blond hair also faithfully reproduced Namikaze Minato's bloodline.
And now, the biggest difficulty for Uzumaki Naruto is not the problem of chakra control ability.
The Nine-Tails Chakra is not ownerless. The Kurama in its body is the creature that can perfectly control the Nine-Tails Chakra.
It is impossible for Uzumaki Naruto to control the Nine-Tails' Chakra without Kurama's permission. Only when he is overly excited, the surging Tailed Beast Chakra in his body will overflow unconsciously, forming the Tailed Beast Coat and Tailed Beast Transformation.
But this is not something that Uzumaki Naruto can control on his own, but rather he uses his own chakra to forcibly control the power of the Nine-Tails.
So far, Uzumaki Naruto's way of using the Nine-Tails is mainly through the Bagua Seal on his body. After converting the Nine-Tails' chakra into his own chakra, Naruto can use it freely.
But this conversion has its limits. If Kurama interferes, the amount of converted chakra will be greatly reduced.
Such a situation is extremely unfavorable for Uzumaki Naruto, the Nine-Tails Jinchuriki.
In Uzumaki Naruto's current state, let alone a perfect Jinchuriki like Killer Bee, the Eight-Tails Jinchuriki, he is even worse than the previous Six-Tails Jinchuriki Yutaka and Yukito who was captured by the Akatsuki organization and died after the Two-Tails Matatabi was taken away from his body.
Although the Nine-Tails is the strongest tailed beast, even if it is split into two halves, the Nine-Tails sealed in Uzumaki Naruto's body is still the strongest.
The Nine-Tails Jinchuriki has the highest potential, but how to unleash this powerful force is the most important thing.
At present, Naruto should at least have the ability to protect himself, let alone become an indispensable combat force on the main battlefield.
And there are more troubles that need to be solved by Uzumaki Naruto in perfect Jinchuriki state.
When the Ten-Tails Jinchuriki is born, all kinds of powerful Wood Release techniques will surely appear on the battlefield.
If Uchiha Madara performed a large-scale killing ninjutsu such as Wood Release: Flower Tree World Descent, he would need a perfect Nine-Tails Jinchuriki to project the Tailed Beast Chakra onto every ninja, so that they would be protected from damage by this large-scale ninjutsu and maintain the most basic combat effectiveness.
Otherwise, the so-called powerful Ninja Alliance might be wiped out by a powerful ninjutsu from the Ten-Tails Jinchuriki.
Now, Uzumaki Naruto is still far from that state.
Under the Giant Turtle Island, the wounds from the fierce battle had been healed.
The somewhat restless giant island turtle finally calmed down after the careful care of the Cloud Ninjas, and is now falling into a deep sleep again.
Inside the protection of the huge turtle shell, Uzumaki Naruto finally managed to control the red arm transformed by the Nine-Tails' chakra.
The various stones in front of him were grabbed and manipulated by the huge arms and stacked into a tall, thin tower.
“It’s finally done!”
Controlling the chakra of the tailed beasts is not an easy task.
Generally speaking, the invisible substance chakra will only bring mental oppression to people. Only when one consumes oneself excessively will one feel tired.
However, the tailed beast chakra is different. The extremely compressed Nine-Tails chakra has mass in the eyes of the Jinchūriki, and it is quite heavy.
This magical thing between matter and energy will manifest itself in very different ways if you don't understand it.
Now, even with Uzumaki Naruto's physical strength and chakra, his body felt like it could not hold on any longer.
“It took a little longer than expected, but it’s not bad…”
The Eight-Tails Jinchuriki Killer Bee has been waiting for a long time. These days, Killer Bee has been a bit bored as he can't sit still.
As a relatively famous rapper, performing in public is his favorite thing to do.
Unfortunately, the ninja world has not been peaceful recently, even the Hidden Cloud Village has been affected. The ninja coalition is about to be established, and Killer Bee knows it.
If the Two-Tails Jinchuriki was captured by the wooden man and the Hidden Cloud Village remained indifferent, the village's reputation and prestige would no longer be maintained.
What's more, Yumoto was captured alive in front of Killer Bee. For the battle-hardened Killer Bee, it's not like he hasn't experienced his comrades being captured and killed. However, over the years, the reputation of the Hidden Cloud Village has been growing, and Killer Bee has become stronger and stronger. He can even compete with his brother, the Fourth Raikage.
However, the surprise attack on the Giant Turtle Island by the Akatsuki organization led by Uchiha Obito gave him a wake-up call.
After knowing that Yumu Ren was in danger, Kirabi, who seemed heartless, became depressed for a while.
Killer Bee already knows the enemy's desire for the tailed beasts and the Jinchūriki.
Although his brother, the Fourth Raikage, assigned Naruto the task of being an instructor for Konoha's Nine-Tails Jinchuriki and training Naruto on how to control the Nine-Tails' chakra, he also intended to hide Killer Bee for protection.
After all, although the power of the Jinchūriki is very strong, it is not indispensable. There are still many strong people in the ninja world. Without the Jinchūriki, there will naturally be other strong people to fill their vacancies. However, if the Jinchūriki fights poorly on the battlefield and is captured by the enemy again, it will only increase the enemy's strength in vain.
Protecting the Jinchūriki has also become a consensus among the five major ninja villages. Otherwise, the major ninja villages with many conflicts would not send Jinchūriki to this place for centralized management.
Although there seems to be no defense here, the power in the dark is indeed extremely strong. It not only guards against the invasion of outsiders, but also prevents the restless Jinchūriki from acting rashly.
Fortunately, nothing embarrassing has happened so far.
After sitting there for a long time, he stood up, put away the notebook and pen in his hand, and sighed.
"The next training is what I told you before, how to deal with the Nine-Tailed Fox in your body. If you can convince it to provide you with power, that would be the best. If not, you can take it away by force. I have already told you the method. Such an action is quite dangerous. Have you thought it through?"
After completing the training of the tailed beast chakra, Uzumaki Naruto can basically use the power of the four tails without restriction without any problems. However, such power can only be said to go so far. If it were not for the fact that the power ceiling of the ninja world is constantly increasing, even in the previous ninja wars, such strength could have determined the direction of a war. But this is not the case in the upcoming Fourth Ninja War.
"I see. Anything else you want to say?"
Even though he was almost unable to hold on due to the double blow of physical and mental exhaustion, Naruto still didn't want to stop at this moment. He didn't know how many people were looking at him. It was a rare opportunity for him to be noticed by everyone, so he had to perform well. Besides, he was still in Team 7...especially training under the protection of Uchiha Sasuke. How could Naruto, who felt a sense of urgency in his heart, not practice desperately?
"Okay then, you take a rest and recover some chakra. I have something else to do, so I'll be away for a while!"
Unlike in the original story, due to the influence of Mizuki, before the Fourth Ninja World War, not only were there only Eight-Tails Jinchuriki Killer Bee and Nine-Tails Jinchuriki Uzumaki Naruto left, but also Six-Tails Jinchuriki Yudaka and Seven-Tails Jinchuriki Fu survived. Although only a small half of the Seven-Tails was left in Fu's body, causing the power she could exert to be greatly reduced, but after being treated and carefully cared for by Konoha Village, she has recovered to this day and can still use the powerful power of the tailed beasts.
With the intention of not giving up any chance to weaken the Akatsuki organization, the Six-Tails Jinchuriki Yugao also came to the Hidden Cloud Village and was sent to the Giant Turtle Island not long ago.
After a period of time, after some coordination, Tsunade finally persuaded the Takigakure to send the Seven-Tails Jinchuriki Fu out to be protected together with the other living Jinchuriki.
The situation is stronger than people. Takigakure is not unaware of the threat from the Akatsuki organization. What's more, the five major ninja villages are trying to put pressure on Takigakure at the same time. In this situation, Takigakure does not have many choices.
The Eight-Tails Jinchuriki Killer Bee was going to pick up Fu who was escorted from Takigakure to the Giant Turtle Island.
As the host and currently the strongest Jinchūriki, it is only natural for him to take care of the guests who have come from afar. Communication between Jinchūriki is also necessary. After all, there is a layer of separation between ordinary ninjas and them.
…
On the outer layer of Giant Turtle Island, inside a makeshift attic, Team 7 was resting. As the ninja with the best sealing skills in Konoha Village besides Mizuki, Haruno Sakura's exploration of the surrounding environment has come to an end.
"The barrier of Giant Turtle Island is not only for concealment and defense, but also for internal surveillance and imprisonment. It always feels a bit strange."
Although his strength and character are almost up to standard, he is still slightly lacking in experience, especially regarding the political structure of the ninja world and the views of those in higher positions.
The battle-hardened Hatake Kakashi naturally understood this and said with a smile:
"Don't worry too much. This is not to harm us, but to prevent internal changes. After all, the tailed beasts are not safe. Not everyone is like Mizuki teacher, who can play with most of the tailed beasts at will!"
Only a strong person with the strength of the Kage of the five major ninja villages can suppress the tailed beasts to a certain extent.
Many of the Jinchūriki are guys with very unpredictable personalities. If a tailed beast goes berserk, there is no way these strategic weapons will be able to escape.
Wherever there is a Jinchūriki, there is basically a restrictive barrier to suppress the power of the tailed beasts.
"Konoha Village actually has some, but the level of sealing techniques and barrier techniques in the village is not comparable to that of the Hidden Cloud Village. The barrier of Giant Turtle Island is too mundane. Of course, only you can see these problems. In fact, many people can't even tell what's mysterious."
Why did Konoha Village feel confident in releasing the Nine-Tails into the Hidden Cloud Village?
At this time, although the Hidden Cloud Village suffered a great loss at the hands of the Akatsuki organization, the Ninja World War had not yet begun, so it was not time to put everything on the line.
Why did Tsunade feel confident in letting Naruto train in the Hidden Cloud Village?
In addition to the powerful strength of Team 7's Kakashi Hatake, Sasuke Uchiha and Sakura Haruno who are capable of dealing with emergencies, there is also Mizuki's Flying Thunder God Technique which is elusive and can rescue people in time if the situation goes wrong.
The predecessors of the Uzumaki family are already dead. Unless the Fourth Hokage Minato Namikaze and the Second Hokage Tobirama Senju are resurrected, no one should be able to isolate the time and space mark that Mizuki set in Uzumaki Naruto's body.
Sakura and Sasuke seemed a little worried about the safety of Naruto who had not appeared for many days, but Kakashi was still relatively calm. Knowing the inside story, he understood that if there was really a problem, Mizuki would definitely appear here.
However, the Six-tailed Jinchuriki Yutaka of the Hidden Mist Village did not have this luck. And the upcoming female ninja Fu from the Takigakure Village could only hope for the support of the Konoha Village. Only the Konoha Village would protect them for the benefit of their allies.
"Sakura, someone from the Takigakure is coming. The female ninja you met during the Chunin Exam three years ago is also a Jinchuriki. Go say hello. It'll be good to have a female ninja of the same age to look after you. And Sasuke... eh?"
Hatake Kakashi, who was about to say something else, suddenly looked into the distance, while Uchiha Sasuke, who had even better dynamic vision, opened his Sharingan.
A small black dot appeared in the sky, which gradually grew larger. Soon after, a small and exquisite carrier pigeon appeared and flew directly to Kakashi Hatake's shoulder, with a small note tied to its feet.
Kakashi took it off and took a quick look at it, then his expression turned serious:
"A bit of trouble?"
"What's wrong?"
Kakashi's palm burst into flames, burning the information, and then he answered with an embarrassed look:
"Naruto's training has not yet ended, but the enemy has officially issued a declaration of war to the five major ninja villages..."
