On an unknown mountain in the Land of Fire, explosions were heard from time to time, and debris flew everywhere.
Are the people from the Fire Country testing the bomb? Of course not, it is Nagase who is testing the power of the Captain-General Template again.
Nagase had previously discovered through experiments that as long as he allowed the chakra to explode internally to strengthen the body, and then used the power of the god of death to attach to the outside, he could increase his strength significantly.
Although the degree of enhancement is acceptable, it is still a bit useless for Nagase. He is not a pure physical ninja, and chakra is only used to enhance the body.
You should know that his most powerful weapon now is the Sun Breathing Sage Mode's strongest slash, the Fiery Sun Sky Path. If he doesn't restrain himself, he can give the planet where the Ninja World is located a haircut.
If it was just this level, Nagase would naturally not be satisfied, so he started a new experiment.
Nagase has always believed that Chakra is a system with great potential.
Although everyone's method of refining chakra is similar, due to individual differences, there are actually significant differences in chakra.
Just take the people around Nagase as an example. Kushina's chakra is different from that of ordinary people. The reason why Kushina was chosen as the Jinchūriki is not only because of her identity as a member of the Uzumaki clan, but also has something to do with her unique chakra.
Kushina was born with a unique chakra, which had a strong suppressive power on the tailed beasts. So if Kushina was in her normal state, the Nine-Tails would not be able to cause any trouble no matter what.
In addition, chakra also has many magical functions. For example, the chakra left by the old man of the Six Paths turned into a strange state of being dead but not completely dead, and the chakra of Indra Ashura can be reincarnated continuously.
Nagase believes that chakra can do this because chakra has the ability to store information.
Of course, although it is a reincarnation, he is actually another person. Hashirama is the reincarnation of Ashura's Chakra, and Naruto is the reincarnation of Ashura's Chakra. Can we say that Naruto and Hashirama are exactly the same? Of course not.
In addition, Hashirama's senjutsu chakra has super healing abilities, and the chakra of the tailed beasts has even stronger destructive power.
Since ordinary chakra can be combined with natural abilities to become fairy chakra, why can't he combine chakra with the spiritual power of the god of death to create a chakra that has never existed before.
Nagaze thought this was very promising.
Even if he couldn't create a completely new type of Shinigami chakra, Nagase would try to come up with a move that would allow chakra and spiritual energy and reiatsu to coexist harmoniously.
Instead of seeking to find out that one plus one is greater than two, it is fine to first try to find out that one plus one is equal to one.
At present, Nagase's words are one plus one is less than one. If the two energies are used and integrated at the same time, the spiritual power and chakra will cancel each other out, resulting in the final power being worse than pure chakra or pure spiritual power.
Looking at the bumpy ground, Yongze sighed. His experiment just now failed again.
At first, he was thinking about balancing both sides, and the strength of the chakra and spiritual power he used was almost the same, but he kept failing. Just now, Nagase tried to increase the strength of the spiritual power, but found that it would cause problems with the chakra and then expand and explode.
However, Nagaze did not take it too seriously. He quickly began to think about the reasons for the failure and tried to solve it.
Merging the powers of two different worlds is no easy task, even with Tobirama's talent.
So far, Nagase has been very careful in selecting templates, not only looking at the strength of the template, but also considering other aspects of its capabilities.
The second generation template not only gave him powerful water jutsu and a large amount of chakra, but also gave him an extraordinary development talent.
The fact that the Medical Talisman and the Psychic Steel Talisman could be brought to life so quickly was largely due to the second-generation template, and the same was true for the development of some forbidden techniques.
However, faced with such a world-class challenge as integrating the power of two different worlds, Nagase was a little troubled for a moment.
He even had an urge to use the Impure World Reincarnation to bring out the second generation and have him help with the development, which would double the speed.
Of course, Nagase was just thinking about it. If the second generation of the Evil World came out, and saw that it was someone from their own village who was causing trouble, they would definitely beat and scold them.
The village's top leaders also have a hard time explaining this. Among the current Konoha high-level leaders, except for Nagase and Minato, the Third Generation and Utane Koharu are all disciples of the Second Generation.
Nagaze's behavior can be regarded as a serious blasphemy against the second generation. If they were not unable to defeat him, they would have directly labeled Nagaze a traitor and killed him on the spot.
Thinking about the serious consequences of the matter, Nagase gave up the idea of sending the second generation out to work.
After all, the second generation doesn’t know the theoretical system of the god of death. If he summons the second generation, he has to teach him things first before the second generation can help him.
It's really too troublesome, Nagase might as well go find Orochimaru.
In order to achieve immortality, Orochimaru dabbled in both the body and the soul, otherwise he would not have been able to develop the reincarnation technique that allows the soul to enter other bodies.
"Could it be that spiritual power and mental energy have some similar characteristics that affect the balance of chakra and make chakra unstable, causing the explosion?" Nagase fell into deep thought.
After researching after obtaining the template, he discovered that if the spiritual pressure is stronger, the person's spiritual energy will be stronger, which means there is a certain correlation between the two.
But there are still big differences between the two. Nagase cannot use spiritual power to synthesize chakra with body energy.
Although he had just thought of this at the beginning, Nagase was still quite happy to get the exact result. This meant that even if he did not use spiritual power and spiritual pressure to fight, he could still improve his upper limit as a ninja.
The amount of chakra may not be an absolute criterion for victory, but it is definitely an important criterion for measuring a ninja's strength.
If you have chakra as powerful as Hashirama and Madara, any C-level ninjutsu you perform will be beyond the reach of ordinary ninjas.
But if you are just a rookie Genin who just graduated from the Ninja School, then even if you are given a forbidden technique with terrifying power, it is still a question whether you can achieve results in your practice.
Therefore, increasing a ninja's spiritual energy is almost equivalent to increasing his upper limit.
As Nagase was thinking, he suddenly thought of a magical ninjutsu - the Rasengan.
As we all know, Naruto did not learn many ninjutsu. From beginning to end, he basically only used the Multiple Shadow Clone Technique and the Rasengan.
Is it because Naruto is too bad of a student to learn other ninjutsu? Of course not, the Rasengan itself is a highly difficult ninjutsu.
I don't learn other things because one Rasengan is enough.
If Naruto is the protagonist of the character in Naruto, then Rasengan is the protagonist of ninjutsu.
Not only is it an A-level ninjutsu when it comes out, but it also has unlimited possibilities.
Under Naruto's development, there are a series of balls including the Big Rasengan, the Super Big Rasengan, the Rasenshuriken, the Senjutsu Rasengan, the Senjutsu Rasengan, etc.
It can be said that there may be many ninjutsu with more magical or even more powerful effects than the Rasengan, but no ninjutsu has as many possibilities as the Rasengan.
"Since the Rasengan has such great potential, can we give it a try?" Nagase had a flash of inspiration and wanted to try whether he could use the potential of the Rasengan to help him complete the experiment faster.
Nagase did what he said. A large amount of chakra gathered in his palms, constantly rotating irregularly in different directions. Then Nagase infused spiritual power into the Rasengan, causing the spiritual power to begin rotating irregularly as well.
"Eh, they don't cancel each other out." Nagase's face lit up and he exclaimed that the Rasengan was awesome.
Boom!
A huge explosion sounded, and the terrifying energy swallowed up everything around it, creating a huge pit.
Nagaze stood in the center of the huge pit, still in the posture of rolling a ball. He was not injured, but there was a little black ash on his clothes.
Yongze brushed off the dust on his body, then jumped out of the pit.
Yongze saw the unknown mountain outside which had lost one fifth of its body and fell into deep thought.
In fact, he didn't use much strength just now, but still caused such damage. In other words, although the Rasengan just now was out of control, it was also successful in a sense.
At least now it is no longer the embarrassing situation of one plus one being less than one, which shows that his idea is correct.
Nagase stood on the mountain, observing the big pit, wondering why the Rasengan suddenly exploded.
Normally, if the Rasengan failed to be released, the worst that could happen would be that it would not be able to exert its original power, but his direct explosion was really a bit outrageous.
Nagase thought about it and felt that the reason for the explosion of the Rasengan might be the same as the explosion caused by his initial attempt to forcibly fuse chakra and spiritual power.
"In this case, we need to reduce the output of spiritual energy and increase the output of chakra."
The cause of the previous explosion was that the strength of spiritual power exceeded the chakra, which caused the explosion. If the two explosions were based on the same principle, then as long as the ratio of spiritual power was adjusted, there should be no explosion.
Nagase tried a few more times, but this time he deliberately controlled his strength to avoid trying a few more times, and another mountain in the Fire Nation disappeared from the map.
However, the result of the experiment was not what Nagase expected, and the Rasengan still exploded out of control.
Nagase continued to repeat the experiment dozens of times, but the result was still failure.
"Is my idea wrong? Maybe the two explosions were not caused by the same reason?" Nagase fell into deep thought again.
Unwilling to give up, Nagase condensed the Rasengan again, but this time he did not add spiritual power. He simply used the attributeless chakra without any property changes to condense an ordinary Rasengan.
The attributeless chakra without any property changes was spinning rapidly and moving irregularly.
Looking at the chakra ball spinning at high speed in front of him, Nagase showed a thoughtful expression.
The practice of Rasengan is done step by step, from the initial condensation of chakra to breaking the water ball and then the balloon.
If we reproduce every step of the Rasengan and use spiritual power in them, we may be able to find a solution.
… … … …
When Itachi, his friends, and his teacher had finished saying goodbye, the time to leave arrived.
Itachi was leaving Konoha to travel to the Land of Fire, and only people within Itachi's small circle knew about this.
After all, no matter how talented Itachi is, no matter how strong and accomplished he will be in the future, it cannot change the fact that He is just an eight-year-old kid now.
Even the Uchiha clan didn't know that their eldest master was going out traveling.
Apart from his own family, Itachi only told Shisui and Uchiha Izumi about the matter.
Shisui has always been a very special existence to Itachi. On the one hand, Shisui is a senior who is much stronger than him and a teacher who taught him various practical skills.
On the one hand, Shisui and Itachi have a lot in common. Although there is a certain age gap between them, they get along surprisingly well and are close friends.
For Shisui, who was both his teacher and friend, Itachi not only told Shisui about his travels, but also told Shisui about his future goals and the actions he was going to take.
Shisui was also happy for Itachi. Seeing that Itachi was valued by Nagase, Shisui was happy for Itachi from the bottom of his heart.
Shisui can be considered an old man around Nagase. He started following Nagase very early and was arranged by the third generation to be by Nagase's side when Nagase just formed a training team.
He knew Nagasawa very well and knew that Nagasawa was a great ninja who truly had the will of fire and loved Konoha.
Nagasawa is so highly regarded in Shisui's heart, even higher than those Hokage.
It would be the best if the junior you think highly of is valued by the elders you respect.
At the Konoha gate, the entire Fugaku family was present, and Kabuto and others also came to see them off.
Fugaku crossed his arms and said in a deep voice: "Perhaps you are tired of hearing this sentence these days, but as a father, I still want to say it one last time. Safety is the most important thing during the journey, and you must return home safely."
Uchiha Mikoto said softly: "Itachi, you have always been a very worry-free child. Promise your mother to protect yourself."
"Brother, remember to come back soon. Remember, I've been waiting for you." Zuo Zhu said.
Itachi rubbed Sasuke's head and said, "I'll be careful to be safe."
"I hope you can get the answer you want, Itachi, but if you go out traveling, this will be a good opportunity for me to surpass you in strength." Kabuto said with a smile.
"I won't slack off during my journey." Itachi replied with a smile.
"I hope you have a safe journey Itachi." Uchiha Izumi wished.
"Um."
"Your current environment is much better than mine was back then. Come on, Itachi, fight for your ideals." Shisui also blessed Itachi.
"Yes, I will."
Nagase took out two summoning steel talismans and handed them to Itachi, saying, "This is the summoning steel talisman I made. When you encounter danger, just input chakra directly. But you have to be at a suitable distance, otherwise you may be injured by mistake."
"Thank you, Mr. Nagase." Itachi thanked him seriously.
Finally, Itachi walked out of the Konoha gate and went out of Konoha under the gaze of everyone.
After seeing Itachi off, they all left, but before leaving, it was obvious that Uchiha Izumi and Sasuke were not in a good mood.
However, Shisui returned to the training team with Nagase.
"Actually, you did send someone to protect Itachi, right?" Shisui suddenly asked.
Although Nagase had specifically emphasized before that he would not send anyone to protect Itachi, Shisui didn't believe that Nagase would really ignore his disciple.
After all, Nagaze is not a rigid person in this regard. It is impossible for him to ignore it just because someone said something.
Nagase glanced at Shisui and smiled, "Of course we have people protecting us, otherwise there would be too many accidents in this world."
Although theoretically, with Itachi's current strength he should be safe in the Land of Fire, after all, Itachi is still a legitimate Konoha ninja.
But Yongze didn't want to gamble, in case something unexpected happened, he would suffer a huge loss.
What's more, during this period of time, he didn't even allow the Uchiha people to go out on missions, so how could he let Itachi go out alone
