Ninja Academy.
Office.
"Sensei Satoru, long time no see." Iruka's face lit up with joy when he saw Satoru.
He immediately went to greet him.
It really has been a long time.
Satoru is busy now, and he's also busy after becoming the Head of Instruction.
Not only has he not seen Sensei Satoru in a long time.
He hasn't even had time to chat with former teammates and classmates like Ibara Keisen and Mibu Shinobu.
"Long time no see, Iruka. You're already the Head of Instruction, that's good. Keep up the hard work in the future."
Satoru patted his shoulder with satisfaction.
Among his three disciples, besides Ibara Keisen, Iruka was the most outstanding.
Cough—being second among three is indeed a bit... "And Ebisu, long time no see. I heard you also wanted to test for the Head of Instruction position.
Did you pass?"
Then he looked at Ebisu.
His tone was very teasing.
Ebisu's face turned red upon hearing this: "Hmph, I gave Iruka face because of you. I'll take it later."
"Haha, I understand." Satoru laughed heartily.
Ebisu: "I heard you're inspecting the Ninja Academy. Aren't you supposed to be retired? Why are you still working?"
He kept hearing about it, but it never felt like retirement.
Whether intentionally or not, Satoru was always involved in Konoha's development.
There was no sense of retirement at all.
It was simply absurd.
"Retirement means not working, and doing things you like more.
I am a successor of the will of fire, and now I want to pass down the will of fire.
That's also something I like to do."
Satoru said.
Now he just wanted to use some small tasks to relieve mental pressure.
Developing the Ninja Academy was perfect for this.
Iruka: "Sensei, then what's the purpose of your visit this time?"
He knew his sensei was coming to inspect, but he didn't know what he was going to do.
"I want to see if the Ninja Academy has any other needs, and I want to get some opinions from you all."
Satoru couldn't do everything himself.
As soon as the topic came up, everyone immediately became energetic.
This was the legendary Ninja; they finally got to see him.
All the teachers, except Iruka, eagerly expressed their opinions.
They hoped to leave a good impression on Satoru.
"I believe there's still room for improvement in the Shuriken course's analyzer for calculating Shuriken usage."
"The Ninja trap course has fallen behind and needs new lessons."
"Due to Senior Satoru's new training methods, students' Chakra control is stronger than before, causing many Chakra courses to fall behind and require comprehensive adjustments."
There were still many problems.
In all aspects.
Kakashi hadn't yet finalized the adjustments for the Ninja Academy.
It was simply because Konoha was too busy at the moment.
Satoru was shocked by what he saw.
With Shikamaru and Shizune's help, Kakashi still had a mountain of documents to process every day.
And he still hadn't finished them.
The rapid development led to various tasks that almost worked Kakashi to the bone, turning him into a Ninja dog.
This was even with the assistance of various Ninja.
And he even used Shadow Clone.
Fortunately, Kakashi's intelligence was incomparable to Naruto's, and he handled everything very well.
So he still had time to read make-out paradise and such.
He still had some time.
If it were Naruto, even with Shikamaru and others helping, he would be exhausted like a dog.
"Mm-hmm, you all spoke very well."
Satoru stored everything in his mind.
Indeed, to say nothing else.
The Chakra control methods he left for the Ninja Academy made the entire Ninja Academy's Taijutsu training incompatible.
It wasn't about going backward.
Rather, some things couldn't keep up.
With improved Chakra control ability, the difficulty of all other courses would decrease.
If there were no changes, it would mean that both the training effect and efficiency had changed.
After some time, Satoru finished collecting their opinions and prepared to start his work.
"Sensei, please sign this first." Iruka was not at all polite, handing over a photo.
It was Satoru's handsome picture.
Then the other teachers also handed theirs over.
Their children also had fans of Satoru.
And they didn't stop them.
These teachers were also fans.
Even Ebisu handed his over, but it wasn't one or two pictures.
It was a stack.
Satoru looked at him, speechless: "I say, Ebisu, what's wrong with you? Do you think I'm a signing machine?"
"Please, you must sign them. I need them." Ebisu said, blushing and thick-skinned.
The next Head of Instruction would definitely be him.
Bathing Figure Technique.
Several pens flew out, controlled by Chakra threads, signing for them.
When this move was revealed, they were all astonished.
The pens were writing by themselves.
--- The discussion at the Ninja Academy ended.
However, Satoru's actions did not end.
He still visited various classes to observe the students' lessons.
Time passed quickly.
But some places were changing.
For example, Kaguya's dimension.
Various dimensions.
Satoru began his modifications.
His first goal was to create a suitable training ground for Taijutsu Ninja.
And Kaguya's dimension was perfect.
It had ice, desert, water, and various spaces.
It perfectly set up a Taijutsu training ground.
In addition, the Wind Breath Valley was also used by him as a training ground.
He modified these places.
Cold, scorching heat, swamps, lightning, gravity, unknown creatures, no soil, no life—various ideas unfolded around Satoru's thoughts.
He began to modify Kaguya's dimension.
There were also modifications of other terrains discovered in the Ninja World.
Such as Flame Mountain, Wind Breath Valley, and islands where various Summoning Beast existed.
These were all his creative spaces.
He wanted to use his abilities to develop these places into super training grounds for Ninja training.
However, he didn't spend all his time here; these tasks were just a diversion from his main goals.
His true work was to develop his own abilities.
Genjutsu needed improvement, especially against the Ōtsutsuki.
He also needed to become more familiar with the Ōtsutsuki's bodies.
And the upgrade and development of Unmeasurable Empty Place were also underway.
This Ninjutsu was his early trump card, but it was just a type of Sealing Jutsu.
Now it needed to become a permanent Ninjutsu, or as Orochimaru said, it needed to be fixed in one place to defend against possible future sight.
Fixing it in one place was fine; that was relatively easy to achieve.
But ensuring it would be effective against enemies was still a bit challenging.
Satoru, however, didn't want to complete it so simply.
What he needed was to develop this Ninjutsu to be even more powerful without affecting his own life.
"Eight Extremes Heaven has a chance of being developed. Recently, Shion from Hidden Sand Village is now a Jonin of Sunagakure.
His Taijutsu is also very good. Perhaps I can go find him for some training data."
Shion's Seven Heavens Breathing Technique and Might Guy's Eight Gates are both powerful Taijutsu.
Both could be used for experimentation.
And his goal was the Taijutsu he thought was the coolest when he was a child.
It was also a tribute to a classic.
