Naruto: Master of Yin chakra

Konoha Great Gate.

Iruka and the other two, with their backpacks on, were already waiting for Satoru.

"The official mission has finally started! Watch me finish this mission in one day, hmph hmph." Iruka was full of confidence.

It was just about finding someone. After doing missions for so long, his tracking skills for finding cats and dogs were superb. Iruka was incredibly confident.

Mibu Shinobi and Ibara Keisen were the same. Though they had been swayed by the Will of Fire to be enthusiastic about D-rank missions, deep down they still looked forward to higher-level missions.

This information-gathering mission to find someone was rated B-rank because it involved a Ninja.

Hence, they were highly motivated.

"Why isn't the captain here yet? We've been ready for so long."

"Sorry, sorry, saying hello to my fiancée took a bit of time." Satoru appeared behind them at some point.

Bang!

The sudden sound made their hearts jump.

They only relaxed after hearing their captain's voice.

Iruka patted his chest: "My Captain-sama, scaring people can scare them to death."

"Also, Captain, how did your girlfriend become your fiancée?"

"We've set the wedding date! Get ready to drink my wedding wine, hehe!" Satoru boasted.

How many ninjas in Konoha's future wouldn't have wives? Besides the pre-arranged pairings of the Twelve Strongest Ninja, Kakashi's generation only had Yuhi and Asuma, and Gekkō Hayate and Yūgao Uzuki.

Now that he was one step ahead, he could mock them later.

"Also, Ninjas must always pay attention to their surroundings, and know when it is rest time and when it is time to be in a state.

You can't always keep your state tense, that will damage your mind.

Nor can you relax your guard, because there could be enemies at any time."

Finally, Satoru lectured.

This was practical knowledge, practical knowledge for a Ninja's survival, summarised from the many Ninja memories he had seen, combined with his own experiences.

"Yes, Captain."

What Satoru said made a lot of sense, but they were unconvinced. How could a person always be on guard? Even the greatest Ninja couldn't do that!

"Alright, let's go! Tanzaku quarter of the Land of Fire."

...

Whoosh whoosh!

Four figures advanced through the forest in a wedge formation.

"According to Hokage-sama's intelligence, Asuma appeared in Tanzaku quarter two days ago, but it was just a fleeting glimpse. Once we reach our destination, we will immediately begin gathering intelligence, understood?"

Satoru instructed the team.

In Konoha, he was a teacher; outside Konoha, he was the team captain, and he couldn't be negligent.

"Yes, Captain."

Satoru's serious expression infected the three of them, and their expressions changed from joyful to serious.

Whoosh whoosh!

Satoru occasionally cast his perception on a few of them, and finding that they had not failed his teaching in attaching Chakra to their feet, the corners of his mouth curved slightly.

Improved focus indeed had great use for Chakra control. In this past month, the three of them were not only able to focus their attention at any time, but also to refine their Chakra for counterattacks in a short time when judging the surrounding environment.

As for techniques like tree climbing and water walking, they mastered the skills within a few days, and by now, they could even use them while travelling.

Half a day later.

The four of them landed in Tanzaku quarter, which was a town, and quite lively.

After finding an inn as a meeting point, the four split up and scattered to start gathering information.

Satoru walked alone on the main street, observing everything around him. His powerful brain and profound knowledge allowed him to record everything he perceived in his mind.

The advantage of a sensory Ninja came into play; within a few kilometres, not much could escape his discerning eyes.

From the battlefield to his current experience in mind-reading, it made processing this information as easy as picking bird eggs from a nest.

"Asuma, judging by what the Third Hokage said, he seemed to want to go out and find the 'gem' in his heart, right?

"And according to the original work, it seems that before returning to Konoha, Asuma served as one of the Guardian Twelve Ninja for the Daimyo, until he found the 'gem' in his heart.

"Should I just wait for him in the Capital of the Land of Fire?"

Various pieces of information about Tanzaku Quarter flashed through his mind: beautiful women at the hot spring inn, the Land of Exchange downstairs, big-breasted women at the casino...

Wait...

After perceiving more carefully, a huge Chakra signature entered his mind. There was also a slightly smaller Chakra signature next to her.

"It can't be such a coincidence, can it?"

Satoru sighed in his heart at how small the world was. Although he was unwilling to believe it, it was indeed Tsunade, the dream goddess of countless Hokage fans.

The gambler among Konoha's sannin.

But what did that have to do with him?

He already had his goddess. After perceiving for a moment, he shifted his attention away.

He just kept the information in his mind.

All external intelligence could be useful.

He focused his perception on the three little ones.

They were quite diligent, seemingly constantly inquiring about Asuma's information.

Iruka went to the inn to inquire, and Mibu Shinobi went to the hot spring inn to inquire.

Ibara Keisen was a bit more astute, going to the grilled sausage stand and noodle shop, these two pieces of intelligence pinpointing Asuma's preferences.

As for him, he already knew that Asuma would go to the Capital of the Land of Fire. Having nothing to do, he returned to the inn, picked up a notebook, and leisurely drew and wrote in it.

Regarding his ultimate ideas for the Genjutsu series.

First, Historical Rewrite: inserting a piece of history into the enemy's memory, inserting one's existence into the enemy's history, thereby changing the enemy's perception of oneself.

Second, Kyoka Suigetsu: Genjutsu that manipulates the enemy's form, touch, shape, and five senses, thereby achieving true deception.

Third, Pupil Setting Hand: developed based on secret techniques, utilising Yin Release's ability to create form from nothing, deceiving heaven and earth, deceiving oneself, thereby achieving the path of Genjutsu controlling the weather of heaven and earth.

During the period of teaching Iruka and the two others, he learned more than just Barrier Ninjutsu. Genjutsu had always been his most researched area.

And the three ultimate series of Genjutsu were the three relatively difficult-to-break ultimate Genjutsu he had conceived during his two years of exploring Genjutsu.

It's just that the difficulty is very high, and each one could be a decade-long project, so he had to make choices.

At the same time, he didn't miss any time for research.

Time spent on research passed quickly. The sky soon darkened. Sensing the three little ones returning, he put away his notebook.

Knock knock!

"Come in."

"Ah, I'm so tired! I didn't realise finding people was so much harder than finding cats and dogs!"

The three of them walked in, panting.

Satoru asked: "How was it?"

Iruka said dejectedly: "Not a single clue. It's as if he never appeared in this town."

Mibu Shinobi: "I also didn't gather any information about Asuma-senpai."

Ibara Keisen, however, smiled: "Asuma-senpai did appear two days ago, and even ate a lot of grilled sausages at the grilled sausage stand.

"But there's been no news of him since."

The other two looked at him in surprise, not expecting there to be actual intelligence!

Satoru praised: "Ibara did well. You two, I hope you can learn from Iron Wire about intelligence analysis."

He was indeed praising him. Don't underestimate those small differences between a Chunin and a Jonin.

Iruka looked unconvinced: "Damn it, you got to shine this time. Next time, I definitely won't lose."

"Then what about you, Captain?

What intelligence did you gather?"

After the three of them finished reporting their intelligence, they all looked at Satoru.
