The Death Forest outside Konoha Village.
Haruki stood by a small stream.
Streams of water seemed to have a mind of their own as they flowed into the balloon in his hand, quickly filling it up.
"Simply speaking, the Rasengan is to concentrate your own chakra in the palm of your hand, make it rotate randomly, and then compress it to form a chakra ball with no attribute."
Haruki threw the water balloon to Minato Namikaze.
"In the first stage, make your chakra move randomly until the water balloon bursts."
"Okay, teacher."
Minato Namikaze held the water balloon, holding his breath and concentrating. Under his control, chakra slowly seeped into the balloon.
In the faint light, the liquid began to spin violently.
Haruki nodded.
Apart from his bloodline, Minato Namikaze's talent was self - evident.
He was among the top talents in the entire Naruto world.
Compared to Naruto Uzumaki in the original story, Minato Namikaze could do a decent job after just hearing the instructions once.
Haruki estimated that this stage would pass quickly.
While keeping an eye on Minato Namikaze's training, Haruki pondered his next plan.
His current main occupation was teaching.
After all, he was a Medical Ninja.
He was rarely assigned dangerous tasks.
In comparison, most of his work was to handle logistics.
Teaching at the Ninja Academy was much more interesting than working at Konoha Hospital.
It was quite rewarding to gradually change the minds of these little guys.
But Haruki naturally wouldn't be satisfied with this.
Education was a very long - term job.
It would take at least ten years to see the results.
Moreover, no matter how perfect the education was, there would always be some who slipped through the net.
Haruki thought of Orochimaru.
His next plan entirely depended on Orochimaru's research.
Three years ago, after he got to know Orochimaru, he casually revealed some high - school biology knowledge, which finally piqued his interest.
After a friendly exchange, he and Orochimaru reached a consensus.
He provided Orochimaru with funds, knowledge, and various research ideas.
And Orochimaru worked for him.
Of course, Orochimaru would never imagine that the topics of immortality, Cursed Seals, cloning, etc. that Haruki mentioned were all from the original story.
But he wasn't at a loss either.
In the original story, although Orochimaru was a scientist, his research path was rather deviant.
With Haruki's guidance, now his research object had become the essence of chakra.
Just as Haruki had told Orochimaru.
Theoretically, it was impossible to learn all ninjutsu.
But if you mastered the essence of chakra, how it was formed, what it was composed of, why there were nature changes, and why there was a distinction between spiritual energy and physical energy, you could fundamentally understand all ninjutsu, master any ninjutsu, and might even figure out the so - called Kekkei Genkai.
This completely new perspective opened Orochimaru's eyes.
He threw himself into scientific research.
As for the Hokage position.
Orochimaru said:
The Hokage? What the hell is that?
It'll only slow down my research.
"I wonder how the research on the Cage Bird jutsu is going?"
Haruki hadn't been to Orochimaru's place for some time, so he didn't know his progress for the time being.
"Minato, don't be lazy."
He suddenly turned his head and looked at Minato Namikaze, who was out of breath.
"Te...Teacher, I... I can't go on..."
Minato Namikaze sat on the ground ungracefully. Although he had higher talent than his son Naruto Uzumaki, he didn't have the Nine-Tailed Fox, so his Chakra was relatively much less.
"How can a man say he can't do it? Here you go."
Haruki threw a paper box over and then formed a Hand Seal with one hand, and the light green Chakra fell on Minato Namikaze. The fatigue instantly vanished.
"Military Rations Pill?"
Minato Namikaze opened the paper box and recognized the pill inside.
He took one, and his body was immediately filled with Chakra.
Haruki glanced at him and, seeing that he had regained his fighting spirit, continued to think about the Cage Bird jutsu.
He asked Orochimaru to research the Cage Bird jutsu.
Not to release it, but to make a slight adjustment.
The original purpose of the Cage Bird jutsu was to prevent the leakage of the Byakugan. However, over time, it became a means for the main branch of the Hyuga clan to control the branch family.
What Orochimaru had to change was the control of the Cage Bird jutsu.
From being controlled by others to self-control.
No matter how harmonious the relationship seemed on the surface, if one's life was in the hands of the other, it was impossible for the relationship to be truly like that of brothers.
The most typical example was Neji Hyuga.
This tragic genius.
The reason Haruki went to so much trouble was that he valued the ability of the Byakugan.
Although it was extremely difficult to advance to the Tenseigan, in his opinion, the Byakugan was more strategically significant than the Sharingan.
It had extremely strong auxiliary abilities.
Whether used on the battlefield or in medical treatment, its value was far greater than that of the Sharingan.
After Haruki decided to reform Konoha, he set his sights on the Byakugan.
Apart from using it for reconnaissance, he had two initial ideas. One was to form a special long-range military unit. Isn't the Byakugan better than an eight-fold scope? The other was to use it in medical treatment. The Byakugan was like an X-ray at all times.
As for the Gentle Fist of the Hyuga clan, it was indeed good in close combat, but in the later stages of the Hokage era, everyone was piloting high-tech mechas, using cannons, there were also the Impure World Reincarnation and hundreds of thousands of White Zetsu. How many could the Gentle Fist defeat?
Do you think he's like Master Ye, who can fight ten at once?
Lost in thought, Haruki raised his hand and sent a burst of Chakra to Minato Namikaze, eliminating his fatigue.
Minato Namikaze twitched the corners of his mouth.
Although his body was no longer tired and his Chakra was replenished by the Military Rations Pill, his spirit really couldn't take it anymore.
He finally got a taste of what it's like to be an office slave.
That feeling of working seven days a week without a break.
"What's wrong, Minato?"
Oh!
"Nothing... It's okay."
Why does it seem that Teacher is a bit sly?
No, it must be my imagination.
Teacher is also doing this for my own good.
Minato Namikaze secretly cheered himself up and started training again.
For the whole day, he trained until he was dizzy.
But every time he got tired, Haruki would always use a Medical Ninjutsu on him.
"I did it!"
At dusk, Minato Namikaze's cheering suddenly rang out.
But then, he slumped.
His spirit was really too tired.
"That's enough for today. Go back and have a good rest."
"Thanks, Teacher," Minato Namikaze said weakly.
"By the way, there's something I need to tell you. You need to be mentally prepared."
As if remembering something, Haruki slapped his forehead and showed a smile.
Hearing this, Minato Namikaze felt a shiver in his heart and had a bad premonition. He stammered, "Teacher, what do you mean?"
"You know, the essence of Medical Ninjutsu is to accelerate cell division, but this will shorten one's lifespan."
"So, did the previous use of Medical Ninjutsu cost me some of my lifespan?"
Minato Namikaze didn't know how to feel for a moment.
This teacher must be a scheming one, right?
"No, how could I do such a thing?"
"Huh?"
Minato Namikaze widened his eyes and suddenly felt a bit ashamed.
He had been too small-minded.
A person like the teacher would never do anything bad to his students.
"So, I used some tricks to deceive your body and delay the feeling of fatigue. If you have any adverse reactions when you wake up tomorrow, it's all normal."
"???"
Minato Namikaze stood there, stunned.
When he came to his senses, Haruki had already disappeared.
Hoping against hope that it wouldn't be too troublesome, Minato Namikaze fell asleep.
Then, the next day, he almost fainted on the spot.
His whole body felt as if it wasn't his own.
He was overwhelmed by exhaustion, numbness, pain, and all kinds of other discomforts.
