Naruto: Master of Yin chakra

"Hokage-sama has already dispatched support to the Land of Iron to gather intelligence. We just need to patrol the border and prevent Kumogakure from invading the Land of Fire," Hayama said.

Upon hearing this, Satoru scratched his head, already a hundred per cent willing.

If they had to infiltrate the Land of Iron to gather intelligence, that would be truly difficult. Espionage is the most dangerous and difficult Ninja job.

Although the Land of Iron is a neutral nation, it's not like the Five Great Nations, where Ninjas who enter without proper procedures are deemed invaders.

Kill.

The Ninja Killer profession isn't just for show.

As the largest military organisation in a nation, they typically use decisive methods.

Even though the Land of Iron is neutral, it won't allow you to casually gather national intelligence. If discovered, it's very difficult to escape.

When reading the original work, I thought the strength of other nations besides the Five Great Nations was incredibly weak.

But after truly experiencing it, Satoru realised it wasn't like that.

That weakness was a comparison between major powers, not a comparison of one person against an entire nation.

For example, when the original work said Sasori's puppet Ninjutsu could destroy a nation, it meant a nation with only a few cities, not a nation like the Land of Iron with hundreds of towns.

According to Satoru's memory, if he wasn't mistaken, the religion that gave birth to an immortal like Hidan was in the Land of Hot Water.

However, Konoha's subsequent investigation into the Land of Hot Water didn't make much progress; they only knew there was an evil religion within.

This shows that the strength of other nations cannot be easily breached by one person, and the Land of Iron is no exception.

"Oh yeah, so that means we just need to guard the border, and once the Garrison time is over, we'll get an S-rank mission?" Anko asked, quite excited.

This would be her first time completing an S-rank mission alone.

Uchiha Itachi also curved the corner of his mouth.

This would also be his first S-rank mission.

He looked at his captain and Satoru. These two were the key to completing the mission; they seemed like they were sent by the Third Hokage to learn.

This was his thought over the past few days.

Why would the Third Hokage send him and Anko, two relatively weak Ninjas, on such a difficult mission? Besides his Sharingan and Anko's summoning of Ninjutsu for reconnaissance, it was probably also for training.

This kind of nurturing from the Third Hokage truly treated the Uchiha as villagers.

But, the clan...

Itachi shook his head, hoping things could still be eased.

Otherwise...

"Yes, but we also need to be ready at all times. If anything happens to the support dispatched by the Third Hokage, we will need to reinforce them," Hayama nodded.

It's not that simple.

Until the situation in the Land of Lightning is clear, Konoha still needs to be prepared for war; they can't relax just because they have a little intelligence.

Satoru stretched: "There are no small matters on the battlefield. Everyone, be ready at all times. We cannot relax until the mission is over."

Itachi and Anko nodded.

...

Another half a month passed.

"Go, Itachi, go, Uchiha!"

At the temporary base, Satoru watched Hayama and Uchiha Itachi face off, a red flag appearing in his hand at some point, which he waved continuously.

Anko, beside him, watched speechlessly.

She thought she was already 'chuunibyou' enough – yes, that's the term Satoru coined – but she didn't expect this guy to be even more 'chuunibyou' than her.

Clang! Clang!

Hayama's katana clashed rapidly with Itachi's small short sword, sparks flying occasionally, each strike perilous.

Itachi, at such a young age, was quite proficient in swordsmanship. Under the dynamic vision of his Sharingan, he gradually managed to keep up with Baiyun Zaojian's attacks.

The Uchiha style swordsmanship was truly put to good use in his hands.

This was their daily routine now.

Sparring.

Training the youngsters.

For half a month, nothing major happened at the border. Most of the time was spent on routine patrols.

Given this,

Satoru and Hayama would each take turns resting to conserve stamina for potential enemies, while the other would accompany Itachi and Anko in combat practice.

Currently, it was the captain's fight with Itachi.

Limited to swordsmanship,

To cultivate Itachi's practical swordsmanship.

Satoru could tell that Itachi's talent was truly that of a chosen one. His progress in learning swordsmanship had already reached half of his speed!

Although he just practised casually.

Of course, while he thought that, the flag in his hand kept waving.

Such opportunities to relax during work were rare.

"Hey, stop shouting! I need to focus on watching the fight and learn something!" Anko couldn't take it anymore.

Satoru looked at her suspiciously: "You're still learning? I feel like you're already a bit arrogant with the secret Ninjutsu you learned from Orochimaru. I can't believe you when you say you're learning."

Hearing the word "arrogant" made Anko angry.

He had said the same thing when she fought Satoru yesterday.

At that time, she was confident that this man, two years older than her, only had a bit more combat experience than her, and his Genjutsu was mediocre. The last time, she was just careless.

Yesterday, when fighting him, Anko used the snake-style secret Ninjutsu she learned from Orochimaru, confidently preparing to give him a hard time.

Unexpectedly,

He fed her a strange-smelling Genjutsu and mocked her for being arrogant, saying she hadn't even learned how to dispel Genjutsu properly.

Now she felt nauseous.

Of course,

She had to admit, Satoru was a genius.

But Itachi, who was currently fighting, was a genius among geniuses.

With his Sharingan Bloodline Limit, exquisite swordsmanship, impressive Taijutsu, mastery of Fire Release, and formidable Genjutsu, how could he know so much at such a young age?

She thought she had already analysed his intelligence after fighting alongside Itachi for the first time, but unexpectedly, she lost in a fight a few days ago.

Sometimes she wondered, who was the Chunin, and who was the Genin!

"Itachi's talent, without the internal friction of his youth, if he lived to Boruto, he might even say, 'Sasuke, you've slacked off, you're as weak as a Six Paths.'" Satoru complained in his heart.

What a pity,

Besides the influence of his Uchiha bloodline, Itachi's ideology had also taken root and sprouted during the clash of ideals over the years, and it couldn't be changed.

Unless one day,

Satoru's ultimate Genjutsu, inserting into history, is completed, thoroughly modifying memories, there's still a tiny possibility.

But Itachi wouldn't wait for that.

Nor would he allow someone to rewrite his memories.

Clang! Clang!

Itachi didn't know the two behind him were complaining about him. At this moment, he struggled to use his Sharingan to perceive his captain's movements and counterattack.

He learned a lot from this.

Satoru had said that all Ninjutsu have weaknesses; Taijutsu and swordsmanship should be the same.

But he quickly discovered in battle that even though he perceived his captain's intentions, he couldn't counterattack due to his body's limitations.

"Is this what Satoru said, learning diverse methods, otherwise even if you analyse the enemy's moves and tactical intentions, you still can't defeat them?" he pondered.

Clang!

Hayama placed his sword on Itachi's neck, ending today's sparring session.
