Immortality begins with the ninjas of Konoha.

In late November of Konoha Year 43, spurred on by the 6-year-old Chunin Hatake Kakashi, the training frenzy at the Ninja Academy continued.

On weekends and holidays, more teenagers choose to come to the playground. Even though the weather is getting colder, it cannot stop everyone's enthusiasm for exercise.

Obito Uchiha, who was at the bottom of the theoretical class, gradually showed his talent in the practical class, while Might Guy, who was admitted as a replacement, became an excellent student. Both theory and practice were thriving!

"...496..."

"...497..."

"...498..."

"..."

Watching Might Guy gradually break through 500 laps and keep running, the few people who collapsed on the sidelines were completely numb, and no one wanted to laugh at Guy anymore.

"This guy is a genius too!"

Sarutobi Asuma's face showed admiration as he stared at the green figure and murmured in praise. Ebisu, who was still panting heavily with his hands on his knees, straightened up and agreed:

"Yes, Ryosuke-sensei is right. Guy will become an excellent ninja in the future."

In one year, Matt Kai reversed his classmates' prejudice against him, and his visible progress was repeatedly praised by his teachers.

Completely admitting defeat, Genma Shiranui removed his headscarf and slumped to the ground. Thinking about how Might Guy would likely graduate early next April, he uttered a sour remark:

"A genius who works hard? I don't quite agree with that, but Ryosuke-sensei is right."

"Not everyone can keep pushing their limits; after all, we're still just kids."

Talented children often stand out in school and receive special attention from teachers.

No one had any objections to this situation.

Just like how Furukawa Osamu was favored by Tsunade, one of the Legendary Sannin, his classmates felt honored and proud when this was mentioned.

With his hands behind his head, Asuma looked at the sky, which was dyed orange-red. As the son of the Hokage, it was not easy to be compared with geniuses.

"What are you thinking about? Asuma, you're already excellent. It's not a bad thing to graduate a few years later."

Kurenai suddenly peeked out from above Asuma. Seeing the girl's concerned gaze, the boy instinctively stepped aside and said somewhat embarrassedly:

"I'm just a little unwilling to accept it, Hong, thank you..."

Asuma didn't fully express his true feelings; he actually longed for his father's love, but the Third Hokage was too busy and spent most of his time caring for his eldest son.

The two resumed their usual intimate conversation. Seeing this, Obito felt a pang of sadness; Rin, though caring towards him, rarely showed such closeness...

"What?! It's just graduating early. Even if it's a few years later, I'll catch up with these guys during the Chunin stage!"

Feeling uncomfortable from being "showed off," Obito started loudly complaining again. Before anyone else could respond, Might Guy, who was running, immediately gave everyone a thumbs up:

"That's right! This is the burning passion of youth!"

"Geniuses are all hard-working, and I don't want to lose to them in terms of effort."

"If I can't complete 800 laps, I'll walk upside down for another 500 laps!"

For a moment, everyone at the scene fell silent. Might Guy, burning with youthful energy, had dealt them another blow, and the replacement student had successfully made a comeback.

In the evening, at Training Ground No. 3, Hatake Sakumo watched the two short figures colliding back and forth, and a satisfied smile appeared on his face once again.

"Water Release: Water Chaos Waves!"

In the instant he retreated and dodged, Furukawa Osamu, still in mid-air, unleashed a powerful stream of water that instantly submerged his opponent.

Under the impact, Kakashi staggered, his body soaked in water. Before he could retaliate, a sudden arc of electricity made his body go numb.

Kneeling on the ground, Kakashi couldn't believe that his opponent still had the stamina to unleash a series of ninjutsu. Before he could organize a counterattack, Osamu Furukawa had already arrived behind him.

"Such outstanding ninjutsu talent, and her chakra reserves are also exceptional!"

"Don't be discouraged, Kakashi. Shu was just playing to his strengths. You should have realized that sooner."

Seeing his son's reconciliation seal with a look of resentment, Hatake Sakumo couldn't help but smile and comfort him.

In the previous swordsmanship contest, Kakashi had a rare advantage, constantly suppressing the boy and causing him to overlook the issue of chakra.

After putting the short sword back on his back, Furukawa Osamu did not show any smugness. He was still more skilled at using kunai, since the experience of [Gathering] did not include swordsmanship.

"That's impressive, Kakashi. You completely overwhelmed the short swords."

Hearing the praise, Kakashi was pleased to see Furukawa Osamu's sincere smile, but he still turned away and pretended to be indifferent, replying:

"I just practiced for longer."

"Father, is there any way to increase chakra levels?"

"Children don't need to pursue these things; they don't need to force themselves at this age."

Sakumo Hatake gently patted his son's head and smiled warmly. The village no longer needed to send children under 10 to the battlefield; there was no need to pursue power at such a young age.

As the group left the training ground, Furukawa Osamu, who was constantly talking with Kakashi, thought about the changes in his chakra levels over this period.

The amount of chakra extracted instantly increased, and the body's recovery ability also improved. Currently, there is "1.5 ki" of chakra.

It is impossible to determine whether the effect is from collecting the "essence" or from cultivating the herbs using the "essence".

In short, the "secret medicine" he created did indeed change his body, but as for the Sage Chakra, it differed significantly from what he remembered...

...

At night, Ichiraku Ramen's business becomes even more booming.

The constant stream of customers brought a satisfied look to the young man's face, his eyes always narrowed to slits.

"Sakumo-sensei, it seems like the Jonin have been busy with missions lately?"

Osamu Furukawa, who had ordered a bowl of tonkotsu ramen, turned to ask, and Sakumo Hatake nodded, responding with a gentle smile once again:

"It's just that the workload has increased a bit, don't worry, the village will take good care of you."

The mission took nearly three months, and Kakashi, unusually, complained when he heard the word "request":

"Many clients specifically request the father, without considering the issue of rest at all."

"This is the life of a ninja. Every ninja will do their best to enhance the village's prestige."

After saying this, Hatake Sakumo laughed heartily, clearly very proud of his contribution to the village, which drew praise from the diners nearby.

"Thanks to Lord Sakumo, I have the life I have now!"

"The white fangs of Konoha signify a successful commission!"

"Ninjas from other countries don't have a reputation like Lord Sakumo's..."

"..."

Amidst the chorus of praise, Furukawa Osamu's face also revealed a look of reverence, but he was secretly pondering in his heart.

Because of his young age, he was never able to access information about Jonin missions. All he knew was that Hatake Sakumo was highly trusted by the village and the commissioner, and that he was constantly on missions during this period.

Upon seeing this, Kakashi immediately forgot his earlier unpleasantness and felt proud of his father's achievements.

-

A happy and peaceful life makes time fly by.

On January 1st, Konoha Year 44, Osamu Furukawa once again visited Tsunade's apartment to celebrate the holiday together.

Perhaps because they'd spent so much time together, Tsunade stopped hiding her true feelings, pulling out a deck of cards from her chest, and starting a card game on the first day of the new year...

After drawing several bad hands in a row, Tsunade felt a little embarrassed. Seeing Shizune's concerned look, she smiled heartily and looked at Furukawa Osamu seriously, saying:

"Your card skills are also excellent! Xiu, I will officially take you in after graduation. You've passed my test in two years!"

With a significant lead in the medical team's academic standing, Furukawa Osamu, upon hearing Tsunade's words, displayed an expression of excitement and admiration before quickly composed himself and responding:

"I will continue to work hard, teacher!"
