Naruto: All My Targets Are Ninjutsu.

And these are precisely the most crucial factors. Otherwise, Hiruzen Sarutobi, the "Ninjutsu Doctor" who was a disciple of the second generation and was rumored to be proficient in all of Konoha's ninjutsu, would have been the first to master the "Flying Thunder God Technique" without having to wait for Minato Namikaze.

And if even Minato can't do anything about it...

Then he can only consider waiting until he's stronger enough to try and steal the "Lightning Release Chakra Mode" from Kumogakure...

Although the development of the "Instant Shadow Assassination Array" has been temporarily hampered,

However, there is also something to be happy about.

That was a successful breakthrough with the Fireball!

After completing the "Recognition" quest, the "Great Fireball Technique's" affinity rating had already reached over 90. Now, after another week or two of rigorous training, Yu Mikami has finally broken through the final barrier, stepping into a completely new realm—

[Fireball Technique: Affection +2]

【Fireball Jutsu (Affection: 100/100 (Heart to Heart))】

(4 stage rewards obtained: Constitution +4, Trait: Heart of Incineration: Your fire attribute chakra affinity is greatly increased, the power of fire ninjutsu is increased by 240% on the existing basis, and you can continuously increase the temperature and burning ability of "Great Fireball" while consuming a large amount of extra chakra, until it becomes a purgatory fire that even gales and torrential rain cannot extinguish.)

"Wow!"

It really is a 240% increase!

Moreover, this amplification applies to all Fire Release ninjutsu!

At this moment, Yu Mikami felt that the fire attribute part of the chakra flowing in his body had become unusually active and docile, as if it could ignite the air with just a thought.

Of course, the reality is not that exaggerated.

Compared to the Three Bodies Technique, the Great Fireball Technique doesn't grant Yu Mikami an advantage in casting speed; it still requires normal hand seals. However, the Great Fireball Technique only has five or six hand seals, and once mastered, it only takes a second. Furthermore, theoretically, it can be further simplified.

Compared to this increase,

There are also some explanations regarding the "heating" characteristic of the "Great Fireball Technique".

Ordinary flames have temperatures ranging from a few hundred to a thousand degrees Celsius, which have limited destructive power against high-level ninjas, who can even completely withstand such an impact with their chakra. But if Mikami Yu could raise the temperature of the Great Fireball to 6000 degrees Celsius... no, that doesn't seem quite enough.

Let's set a small goal: 10000 degrees!

At that time, the Uchiha clan's Amaterasu will be called "Mini Great Fireball"!

present.

Yu Mikami stood on the training field, his hands forming a mudra: "Snake, Sheep, Monkey, Pig, Horse, Tiger..."

"Fire Release: Great Fireball Technique!!"

boom--!!

In an instant, an orange fireball, seven or eight meters in diameter and resembling a small house, was spat out from Mikami Yu's mouth, sweeping across the sky above the training ground. From a distance, it looked like a raging inferno rising into the sky.

As Mikami Yu continued to infuse chakra, the flames changed color from red to yellow and then to white, creating distorted ripples in the air.

This scene caused Kakashi and Obito, who were conducting ninjutsu training not far away, to stop what they were doing and turn around in astonishment.

Meanwhile, Nohara Rin, who was practicing "water clones" alone, also looked utterly astonished.

"no……"

What kind of ninjutsu is this?!

Fireball?

Whose Fireball can grow this big? Did it eat some kind of super fertilizer?

Obito stared blankly at the small fireball he had just spat out.

Strictly speaking, Obito's Fireball Jutsu wasn't small either, with a diameter of two or three meters, similar to or even stronger than Sasuke's at the same age. However, compared to Mikami Yu, who had received a 240% power boost, it was incomparable. In fact, Mikami Yu had even held back a bit.

Here.

Yu Mikami loosened his hands, rubbed his cheeks which were burning from the heat, and thought to himself: "Flames usually turn white at 1200 degrees and blue at 3000 degrees. It seems that temperatures below 1000 degrees can be maintained stably, but it will gradually become difficult to maintain them at higher temperatures."

"The relationship between temperature and chakra consumption initially seems to be a power function, but it could also be an exponential function..."

I need to test it in detail when I have time to see if I can figure out the formula.

Anyway,

A fireball of the scale that Mikami Yu just released is beyond the capacity of two Chunin-level Water Release techniques to block; it would require at least three or four. Combined with the even higher temperature, it would be difficult for ordinary ninjas to handle.

The emergence of new features not only greatly surprised Yu Mikami,

The same applies to the Fireball itself:

[Fireball Technique: Hehe, is this what it feels like to be connected with Mikami-kun's heart? My body feels so light, there's nothing to be afraid of anymore. Can I use a clone technique?]

[Clone Technique: ? What brings you to this again? Isn't it just "heart-to-heart connection"? The three of us sisters have already reached that state with the mistress~]

[Clone Technique: And you might not know this, but we have a deeper relationship with Xiao San Shang. These past few days, Xiao San Shang has often spent time with the three of us sisters in the small room, turned off the lights, and then… hehe.]

[Fireball Jutsu: ???]

[Phoenix Fire Technique: (Eyes shining, she leans in eagerly) What? Do you have a good story to tell? Tell me in detail!]

[The Art of Turbulent Water Waves: A Superficial Topic]

[Substitute Technique: Stare]

[Water Formation Wall: Stare]

Mikami Yu: "...?"

No, he was truly impressed. How could ninjutsu spread such indecent rumors?

The "small room" refers to the "Instant Prison Shadow Killing Array," right?

Just as he was about to have a serious discussion about the clone technique, trying to figure out exactly which day "that day" meant and whether the "small room" referred to the "phantom stage," a golden light flashed across the training ground.

"Wow, Minato-sensei! You've arrived!"

"Well, how did everyone's training go today? Did you encounter any problems?"

Minato Namikaze smiled gently and inquired about the situation from Yu Mikami and the others.

For reasons of secrecy, Mikami Yu did not reveal the "Instant Hell Shadow Assassination Formation" in front of Kakashi and the others, but only asked some questions about chakra control training. Obito and Nohara Rin then asked him about their difficulties in ninjutsu training.

Once these questions are answered,

Minato Namikaze pulled out a mission scroll: "This is the latest C-rank mission, requiring you to escort several nobles from the Land of Fire to the Land of Tea to visit relatives. The journey is a bit longer than last time, and it will probably take a few more days. You can go back and pack your things today."

"Ugh! Another escort mission! Don't these nobles have anything better to do? We're about to go to war, and they're still running around everywhere!"

Obito grumbled somewhat discontentedly.

Mikami Yu sighed, "Fighting is a matter between ninjas, it has nothing to do with them. If they don't run around, what will we eat?"

Chapter 71 Minato Namikaze: Yu, have you named your new technique yet?

In the Naruto world, nobles and ninjas generally have a division of labor and cooperation.

The former is in charge of the economy, and the latter is in charge of the military.

In name, the daimyo is of a higher rank and is in charge of appointing the kage, but in reality, it depends on the situation. Generally speaking, the more severe the natural conditions of a ninja village, the more dependent it is on the daimyo, unless it can find new ways to make a living on its own.

For example, the placer gold blood successor of Sand Hidden Village.

However, under no circumstances would ninjas proactively target noble families, even those from enemy nations. This is because these individuals are not only potential benefactors but also hold significant legitimacy and authority. Unless they can guarantee they will never be discovered, exposure would invite an attack from the entire ninja world.

As a transmigrator from modern society, Yu Mikami doesn't have a particularly good or bad impression of this group.

after all……

For the ninja world, the feudal system was already quite advanced.

Compared to ninja groups where almost everyone suffers from mental illness, nobles, while perhaps also containing many psychologically twisted and power-abusing individuals, are at least more educated and capable of addressing some social issues. If one truly wants to bring about change in this world, the ninja system is the one more worthy of being challenged.

"...Let's go back and pack our things, get ready to hit the road."

Mikami Yu put his hands behind his head and walked home.

……

The target of this escort mission is a family of four.

The head of the family is named Tachibana Masamune, who is said to be related to the daimyo of the Land of Fire. This trip is to take his wife and two children to visit his brother-in-law Uesugi's family in a neighboring country.

At first, the two children were a little afraid of the group of "ninja masters" wearing headbands and carrying ninja tool bags, but as time went by, their restraint faded, and they began to talk to Mikami Yu and the others, especially Obito, whose intelligence was closest to that of a child:

"Hey, ninja brother, can you really breathe fire?"

The little boy peered through the carriage window and asked.

"Of course I can! It's called the Great Fireball Technique! I'm an expert at it!"

Obito proudly gave a thumbs-up, his eyes gleaming behind his goggles.

Wow! Can you create many versions of yourself?

The little girl also came over, her eyes wide open.

"That's a clone technique! Watch this!"

Obito quickly formed hand seals, and with a "bang," two identical Obitos appeared beside him, making exaggerated faces. "Impressive, right!"

The two children were immediately amused and burst into laughter, their previous awkwardness vanishing completely. Obito, as if he had found a stage, began to talk endlessly about the interesting things that happened in Konoha Village, and even highlighted a few of his own "great achievements".

"...Obito-kun is really good at coaxing children, even though he complained the most at the beginning."

Nohara Rin looked at the scene behind her and said softly.

Minato Namikaze nodded: "Yes, although Obito is usually impulsive, he is actually a very kind child. If I have children in the future, I will definitely get along well with them."

"..."

Yushin Mikami said, "That's right. Obito was the first person to hug Naruto, and probably the person who hugged Naruto for the longest time."

present.

Yu Mikami quickened his pace and walked alongside Minato Namikaze: "Minato-sensei, may I ask you a question?"

"Hmm? Yu, you go ahead and say it."

Minato Namikaze turned his head to look at him.

"Are there any ways to train spatial balance and neural reaction speed?"

Mikami Yu organized his thoughts: "I've recently been developing a fighting style that centers on 'Substitution Technique,' incorporating Transformation Technique, Shadow Clone Technique, and illusionary properties to create the effect of multiple bodies simultaneously assassinating within a certain range. However, I've encountered some problems after trying it out..."

"..."

Minato Namikaze glanced thoughtfully at Yu Mikami.

He had naturally noticed long ago that Yu Mikami's "Stand Technique" was different from others, somewhat like "Flying Thunder God Technique".

And they're becoming more and more like it.

In fact, if Mikami Yu truly possesses the aptitude for space-time ninjutsu and is interested in it, then Namikaze Minato wouldn't mind passing on the "Flying Thunder God Technique" to him. After all, having another person who masters the "Flying Thunder God Technique" would provide an extra layer of security for Konoha's future.

But it's still a bit early.

Firstly, Mikami Yu is only a genin, just 9 years old, while the "Flying Thunder God Technique" is a forbidden technique with an S-rank difficulty level, requiring a high level of chakra reserves, sensory abilities, and observation skills. In all the years since Konoha was founded, only two people have mastered it, demonstrating its immense difficulty.

Secondly, the Minato team has only been established for two months, and Mikami Yu's temperament needs more time to be observed.

but,

The idea that Yu Mikami just proposed really interested him, and it reminded him of the "Spiral Flash Super Wheel Dance Roar 3 Style" that he was currently developing.

"Basic training is crucial for spatial balance."

Minato Namikaze spoke earnestly: "You can try running and jumping at high speed in various extreme terrains, such as cliffs, rushing rivers, swaying suspension bridges, and practicing water climbing under waterfalls to feel the disorientation caused by the impact of the water flow."

"Once you're familiar with it, you can do it blindfolded."

"Another more extreme training method is to jump from a height and try to stabilize your body in the last few seconds before landing. This can greatly improve your instantaneous control over your chakra. However, this is very dangerous and requires thorough protective measures."

"...As for neural responses, this depends more on innate talent. With training, you can try throwing high-speed moving targets or practicing blocking dense shuriken, but these are only tapping into potential based on innate talent. After a certain stage, it is difficult to improve further."

"If you want to break through the limit, there is indeed a way, which is to use chakra to forcibly stimulate the activation of cells and nerves in the body... This secret technique has been studied in depth by the Hidden Cloud Village. Konoha has tried it before, but it seems that there were no results."

"You can ask Lady Tsunade for details. I remember she and Lord Orochimaru were the leaders of this research."

"……I see."

Mikami Yu nodded in agreement.
