Above the ocean.
A giant eagle soared, and on its back stood Satoru, his hands clasped behind him, his eyes gazing at the sea below.
"Water training, after Inuzuka Kiba, it's finally time for others to experience this."
And the ones experiencing his training were, naturally, his two children, already five years old.
Tenyu and Maki.
Some time had passed since the Uchiha clan's destruction, and he had returned to a normal life.
However, his bandages had been removed and were lying in his Ninja tool pouch.
He would use them when needed.
Sigh, being handsome is also a hassle!
Below, in terms of talent for balance and perception, his two children were even stronger than Inuzuka Kiba.
A few months ago, he had taught his two children Chakra extraction, and now they could extract it while moving.
He was very satisfied that they had inherited his talent for perception.
And their physical talent also seemed pretty good.
They were both excellent Ninja prospects.
"Yo-ho!"
"This is so much fun!"
Listening to the cheers from the two below, Satoru also sighed, remarking that they were quite brave.
Back then, Inuzuka Kiba had cried his eyes out.
Tenyu and Maki stood on surfboards, feeling the rush of the big waves, occasionally riding up giant waves and smiling happily at the crest.
They showed no fear at all looking at the blue and black ocean below.
Because they knew that below, the giant whale summoned by their dad was waiting for them to fall.
Even so, falling would be unpleasant; they would tumble underwater for a while before the giant whale would rescue them.
It was a lesson for them.
They had completed the Heaven's Descent training; this was their second step of training.
They had courage from a young age.
Although as they grew older and knew more, their fears intensified.
After confirming there were no issues, Satoru took out a piece of wood from his Ninja tool pouch.
He formed a complex hand seal, and tree branch-shaped lines extended from his right hand, immersing into the wood.
At that very moment, his mind was flooded with various information about the wood: its structure, age, decay time, fibre structure, and more.
"No matter what, after such a long period of research, there are finally results."
If his previous Genjutsu, Pupil Setting Hand, and weather Ninjutsu were considered conventional Ninjutsu, then once this Jutsu was completed, it would be a trump card similar to Earth Release: Planetary Devastation, Shinigami Seal, or All-Killing Ash Bones.
Although this Jutsu had only been developed to a small degree.
It now combines Yin Release nature transformation, Pupil Setting Hand, Mind Reading Technique, and neurological knowledge.
It could utilise the Yin Release's nature transformation of creating form from nothingness, extending the nerves within his body outwards like the Shadow Imitation Technique, to invade the inside of living beings or objects and read their information.
This was not a simple Yin Release Ninjutsu, but a combination of countless knowledge, the crystallisation of his, Satoru's, wisdom.
It would also be his core Ninjutsu in the future.
When this Ninjutsu was performed, the surface of the object would appear in a tree branch-like form, but internally, it would already be covered by his nerves.
Nerves are very tiny things.
The current shortcomings were also very obvious: long hand seal time, short duration, the brain's inability to process the excessive information brought by nerve invasion, which would trigger the body's protective mechanism, the need for touch, and various other problems.
But it was still a good Ninjutsu.
His next research would be to overcome these shortcomings, and then continue to incorporate other knowledge.
The second step of his plan was to use the first step's ability to solve his problem of not having enough Chakra.
"However, it's better to solve these shortcomings first, otherwise, it still can't be used in battle, it can only be used for research!"
Satoru sighed, this Jutsu was indeed the most difficult Ninjutsu to develop in his imagination.
Even so, with just this small achievement, he estimated that he would not hesitate to exchange it with Orochimaru for the Reanimation Jutsu.
This was a true scientific divine technique.
"Oh, ah~"
Tenyu's loud shout came from below, and he perceived it.
He had fallen again.
...
Ninja School.
Whoosh! Whoosh!
Inuzuka Kiba casually flicked his hand, and five Shuriken flew towards Sasuke, while simultaneously forming hand seals.
Sasuke's Sharingan opened, and he also threw Shuriken.
His powerful dynamic vision allowed him to clearly see Kiba's trajectory.
Clang! Clang!
The Shuriken attack failed, but Kiba was not discouraged.
He rushed forward with Piercing Fang.
"Go, Sasuke."
"Sasuke, go."
Outside the combat arena, many girls cheered for Sasuke.
"What incredible talent, I didn't expect that Sasuke, who awakened his eye at the age of eight, still couldn't defeat Kiba."
Mizuki looked at the battle, which was indistinguishable from a Genin fight, with eyes full of envy.
Why did he have no clan, why did he have no talent?
That way, he wouldn't have to be just an ordinary teacher at the school.
Even Iruka's position at the school was getting higher and higher; he was now a homeroom teacher.
He managed several classes.
Iruka didn't notice his gaze, but smiled, saying, "These two children are indeed very diligent. I feel that Kiba has driven him on; he wasn't this diligent before."
This was true.
Since enrollment, Kiba had always been the top student in the school, whether in theory or practice.
At only nine years old, he was already completely on par with Iruka when he had just graduated.
If it weren't for peacetime, Kiba could have graduated early.
And Kiba's diligence also put a lot of pressure on others, after all, he wasn't like Sakura, who was just a theoretical top student and quiet.
Kiba was very flamboyant.
Like a catfish, he made others work hard, otherwise, being mocked by Kiba and those trying to catch up to Kiba would be very unpleasant.
Sasuke was the same; originally, when he met Kiba, he worked very hard to surpass him.
After the clan destruction incident, he studied late into the night and worked even harder.
The entire class, under Kiba's influence, was already the best-performing class in the fourth grade.
There were 8 classes in the fourth grade.
"Fire Release: Great Fireball Technique."
Just then, Sasuke formed a hand seal, puffed out his cheeks, and a burst of flame erupted.
Iruka had already prepared his Chakra, ready to intervene at any moment.
He hadn't expected Sasuke to be able to use such Ninjutsu at this age.
"Too naive."
Inuzuka Kiba's Four Legs Technique allowed him to escape the Fireball's attack range, and he continuously changed direction as Sasuke adjusted his aim.
Woof~
Akamaru barked outside for him, saying he definitely wouldn't let him lose, or it would be too embarrassing.
"How could I possibly lose?"
As Kiba ran, illusions suddenly appeared around him.
Clone Technique.
How could Sasuke fall for such a simple Jutsu? After realising the Great Fireball Technique was useless, he immediately stopped the Chakra supply, pulled out Shuriken, and threw them.
With the dynamic vision of the Sharingan and the ability to see Chakra, how could he not distinguish a simple Clone Technique?
He threw several projectiles at Kiba's real body.
"You fell for it."
Kiba grinned, and from behind the clones, a Kunai with Iron Wire shot out, instantly entangling Sasuke.
With a sniff of his nose, he dodged Sasuke's projectiles, and even the Shadow Shuriken trap hidden beneath his Shuriken didn't hit him.
Whoosh!
