"The Three Basic Techniques are not only the most fundamental ninja techniques but also consume the least amount of chakra. In training grounds, we can use powerful jutsu without worrying about chakra consumption, but it's different on the battlefield."
"Saving a bit of chakra might save your life."
Kyōichi began explaining "his" understanding of the techniques.
Some came from his predecessor, but most came from the system's provided "Three Basic Techniques" knowledge.
Everyone listened intently.
Times were different now.
Continuous wars had left Konoha with a generational gap, with more and more children graduating early to join the war, like Kakashi and Guy.
In this mixed class, many might join the war this year.
Guidance from a battlefield-experienced ninja was truly valuable to them.
Even the most mischievous Obito didn't dare whisper.
"Sensei, how can we use less chakra?"
"Sensei..."
During question time.
Many hands shot up eagerly.
Kyōichi patiently answered each one.
The bell rang.
Class dismissed!
"Alright students, practice on your own after class. If you have questions, you can find me after class or ask next time. You're dismissed if there's nothing else."
Kyōichi felt relieved internally.
His first lesson in the ninja world had gone quite perfectly.
After making an impression at first, teaching wouldn't be too difficult.
However.
Now it seemed his previously prepared lecture notes were unnecessary.
Real teaching couldn't follow a script.
These weren't ordinary students; many were geniuses who would become famous later. Each had their own ideas, and without solid content, he couldn't maintain control.
"By the way, Obito, tomorrow morning's first class is mine. If you're late, you'll run 200 laps around the training ground."
"Huh?"
Obito froze.
Why this sudden announcement before leaving? What if he really was late tomorrow?
"Everyone, see you tomorrow."
After speaking, Kyōichi used Body Flicker to leave.
Back in his office, he immediately checked the system.
At the end of class, he'd heard a system prompt but hadn't caught it clearly.
[First lesson completed]
[Evaluation: Excellent]
[Reward: Water Dragon Bullet Technique]
Water Dragon Bullet?
That technique with forty-four hand seals?
Kyōichi was stunned for a moment.
However.
After claiming and checking it, he realized he'd misjudged the system.
This was the Second Hokage's simplified version, requiring only four hand seals. Combined with his earlier enhanced Senju bloodline benefits, this jutsu reward was definitely not bad.
"I'll try it out when I get back," Kyōichi thought to himself.
Since activating the system and enhancing his bloodline, he hadn't tested the power of his water release techniques or accurately assessed his current abilities.
This wouldn't do.
...
Konoha outskirts.
After class, Kyōichi came here, finding a spot near the river.
Then.
Shadow Clone!
An identical clone appeared.
"Time is precious. You go practice taijutsu techniques, I'll test the power of ninjutsu."
"..."
Damn.
Why don't we swap jobs?
The Shadow Clone wanted to complain, its expression full of resignation.
But.
What could it do as a clone?
No choice.
It had to go find a grove to practice taijutsu techniques. If it could master techniques like Leaf Whirlwind or Dancing Leaf Shadow, that would be profitable.
The real Kyōichi checked his chakra.
He still had plenty of chakra.
"This chakra amount is enough to handle at least three shadow clones working simultaneously without problems. Can't compare to Naruto, but it's much more than adult Kakashi's."
Kyōichi was quite satisfied.
Naruto's power wasn't just bloodline, but also included the Nine-Tails chakra and Ashura chakra - he was completely in a different league.
He looked around.
Finding an empty space, he quickly formed hand seals...
Water Dragon Bullet Technique!
The next moment, water surged up forming a dragon that rose to the sky. With a thunderous roar, the high-speed water dragon smashed into the ground creating a large crater.
The power was impressive!
Though slightly weaker away from rivers, the difference wasn't too significant - just increased chakra consumption.
"Now I have both attack and defense," Kyōichi thought to himself.
Water Formation Wall, Water Dragon Bullet, plus Water Chaos Wave - there weren't many weaknesses in his current abilities.
Of course.
This was only at the chunin and jonin level.
Compared to elite jonin and above, his techniques would seem too basic.
However.
Take it slow - with the system in place, there was still plenty of time ahead.
He got up, planning to go back for a good meal.
As for the clone...
Let it continue training over there.
Just as Kyōichi took a step, he suddenly sensed a chakra fluctuation and turned his head in that direction.
"Who's there?"
"Sensei, it's me."
A figure slowly emerged from behind a tree.
Without even looking.
Just by the voice, Kyōichi knew who it was.
Uchiha Shisui.
"Shisui, do you have something to discuss?"
"Yes, I have some doubts I'd like to ask you about, Sensei."
Shisui immediately bowed.
Seeing that Kyōichi was very gentle and showed no impatience, he walked over, looking somewhat hesitant.
"Tell me about it."
"Sensei, I originally planned to graduate early this year, but after sparring with you, I'm a bit worried... Would graduating early cause trouble for my teammates?"
Shisui voiced his concern.
Kyōichi was stunned for a moment, then felt like laughing.
Seems like he had really impacted the boy's confidence.
After thinking for a moment, he said, "With your strength, you're definitely not weak and won't hold others back on the battlefield. However, unless we're in desperate times of war, I don't recommend graduating this early."
"Please guide me, Sensei!"
Shisui bowed deeply.
"Sit down, let's talk as friends."
Kyōichi sat down and pointed to the grass, gesturing for Shisui to sit as well.
Shisui did as told.
"Do you know the original intention of the First and Second Hokage when they established the ninja academy?"
Shisui shook his head.
"Do you know about the Will of Fire?"
"Where leaves dance, fire burns. The fire's light illuminates the village and helps new trees sprout."
This time Shisui nodded.
The Third had spoken about it, and it was mandatory in ideology classes.
"One of its meanings is that children are Konoha's future. When the First and Second established the academy, it was to delay children from going to the battlefield."
Kyōichi explained.
His grandmother was from the Senju clan, so these historical details had been passed down. It wasn't really a secret, so he didn't need to worry about certain people who might be eavesdropping.
Shisui seemed lost in thought.
"The battlefield can make one mature early, but you're only five years old. If you study for another year or two, both your abilities and thinking will become clearer and more mature. There's no rush to enter the battlefield then."
Kyōichi said.
Does the battlefield lack a few genin?
No, what's lacking are chunin and jonin.
The Third letting children onto the battlefield early was essentially just hoping they would grow quickly under the pressure of war.
"But..."
Shisui hesitated to continue.
He thought about it - the First and Second Hokage seemed to have said similar things, but why were so many children being sent to the battlefield now?
Like Kakashi.
That senpai graduated at age five, and now he's heard he's already become a chunin with outstanding war achievements.
"War can make people grow quickly, but correspondingly, you also lose many things. Being the first to run forward doesn't necessarily mean excellence."
Kyōichi couldn't help but recall scenes about Kakashi.
His previous self had been on the same team as Kakashi.
That guy...
All he could say was, his personality was truly terrible, making it impossible to like him at this stage.
"I understand now, thank you Sensei."
