Immortality begins with the ninjas of Konoha.

"Huff...huff..."

"For Dad, I know I can do it..."

"..."

At the ninja academy's training ground, Might Guy, who had been running non-stop since noon, was running out of energy. His breathing was getting heavier and heavier, and he could only rely on self-encouragement to keep going.

A growing crowd of onlookers gathered nearby, and some of the students who had successfully enrolled immediately mocked Might Guy as he suddenly collapsed.

"You talk about 500 laps, you can't even do 100!"

"A self-absorbed idiot!"

"If you fail the test, you should go home early..."

The jeers from the sidelines didn't affect Might Guy. He got up from the ground and continued running, as if he had broken through his limits. His speed was actually faster than before he fell.

Not getting the response he wanted, nor seeing the scene he had been hoping for, the crowd gradually began to disperse. No one really wanted to see Matt Kay complete his "self-challenge".

As the sun set, Matt Day, who had been secretly watching his son from behind the fence, burst into tears again.

Although he believed this was the wrong approach, he still encouraged himself in his heart:

"You're using the wrong method, Kai, but keep trying..."

"..."

After a thoroughly enjoyable game of kicking cans in the woods next to the playground, everyone was completely exhausted.

Although physically tired, the boys had a great time that afternoon and said goodbye with laughter after resting.

Slumped on the ground, Genma Shiranui, exhausted and with dead fish eyes, took the drink Ebisu offered and gulped it down, muttering:

"He's alive!"

"Why is Xiu always able to catch people so easily? And your stamina is a bit too good!"

Kakashi, maintaining his expressionless face, glanced at his empty wallet, then at Furukawa Osamu distributing drinks on the other side, and gave a somewhat reluctant, simple reply:

"Because he can sense our location."

"This is cheating!"

Upon hearing his friend's complaints, Ebisu adjusted his sunglasses, adopting a proud demeanor, and responded confidently:

"Ninjas are supposed to cheat; it's a kind of 'privilege' of geniuses."

"You always end up being rescued, isn't that something Xiu should say?"

Genma Shiranui and Ebisu got up and started arguing loudly.

Ignoring their childish behavior, Kakashi moved closer to Furukawa Osamu and together they looked at Might Guy on the playground, whispering:

"You can definitely sense my chakra!"

"Who told you to hide in the top of the nearest tree..."

After playing "games" all afternoon, Osamu Furukawa subconsciously made a sarcastic remark.

The silver-haired boy's competitive spirit was too strong, which prolonged the game time, and in the end it was just the two of them "fighting".

"Next time, I'll definitely rescue more teammates than you!"

"..."

Upon hearing Kakashi's serious declaration, Furukawa Osamu almost lost his composure. If he remembered correctly, the other man hadn't played these childish games when they first met two months ago.

Ebisu, who had followed, saw Might Guy collapsed on the ground in the playground and said with great sympathy:

"I remember that his ninjutsu and genjutsu were not good, only his athletic ability was passable."

"There's no need to exhaust yourself like this."

Genma Shiranui sighed in agreement. Hearing the two begin gossiping in hushed tones, Kakashi recalled the scene of meeting Might Guy and his son at the school gate after the entrance exam, and a question arose in his mind:

"Is this the rival Father was talking about? This guy still hasn't shown any outstanding talent."

Falling down and getting up repeatedly, Kakashi grew bored after watching for a while. Among his peers, he still believed that only Osamu Furukawa was his true rival.

Having gathered a great deal of "information" before enrolling, Kakashi trusted his own judgment, temporarily forgetting his father's words, and waved goodbye.

"It's getting late, bye-bye!"

"bye!"

As Genma Shiranui and Ebisu bid each other farewell with smiles, Osamu Furukawa noticed that Might Guy hadn't gotten up for a long time. He went over to him and offered him a drink, saying:

"Impressive physical fitness! Someone's treating today, so don't be shy!"

"I'm already 5 years old, but I can't even walk 500 laps around the track... I've let my dad down..."

After finishing his drink, Might Guy stood up and choked up, whispering. Furukawa Osamu wanted to offer him some words of encouragement, but a dark figure suddenly appeared behind him.

"Kai, you idiot!"

Might Guy, yelling, punched his son, sending him flying. Osamu Furukawa, who had dodged the attack, saw this and his lips twitched slightly.

"Don't shed tears for your efforts; you've just been using the wrong methods of self-discipline!"

"..."

With tears streaming down his face, Matt Day started a "father-son mini-lesson," and the two shouted passionately from time to time. In the end, they hugged each other and cried together.

Feeling incredibly awkward, Furukawa Osamu tried to slip away quietly, but the father and son suddenly appeared beside him. After quickly bowing, they immediately gave him a thumbs-up and loudly proclaimed:

Thank you for your continued support!

"Kai, you've gained friendship through your own efforts; that's what youth is all about!"

After the father and son embraced again, tears welled up and soaked part of their bodysuits. Furukawa Osamu pretended not to see them, nodded in acknowledgment, and after a brief exchange of pleasantries, he finally breathed a sigh of relief.

Walking home, he occasionally greeted familiar shopkeepers. Reflecting on his failed attempt that day, Furukawa Osamu sighed helplessly to himself:

"As expected, he doesn't have the talent for 'talking his way out'!"

"..."

Late at night, Matt Kai, who was having trouble sleeping because he was worried about the supplementary enrollment list, noticed that his father was also awake. After hesitating for a moment, he cautiously asked:

"Dad, is it really impossible to become an excellent ninja without a talent for ninjutsu?"

"Kai, your youth has just begun. You shouldn't back down in your youth. Hard work will definitely pay off."

Hearing the encouragement, Matt Kai fell silent. Although he always appeared confident in public, he knew his father's situation, and tears welled up in his eyes again as he silently made a wish:

"I wish I also had outstanding ninjutsu talent."

-

The last day of March in Konoha Year 42.

"Xiu, I really want to see you grow up healthy..."

"I don't want to die, Xiu. I want to see you again."

"..."

Startled awake, Osamu Furukawa instinctively covered his forehead, the sight of the two people lying in a pool of blood in his dream causing him to gasp for breath.

Noticing that it was not yet 6 o'clock, Osamu Furukawa looked at the photo frame next to his bed.

In the photo, the young couple, Ichiro and Aoi, are only 22 years old. They are hugging a child and their smiles are radiant, their happiness is palpable.

Since the two sacrificed themselves in the early January mission, Osamu Furukawa triggered his "talent" in a somewhat hellish way and completed his first "gathering".

"Aoi, Lord Sakumo will recommend me to become a Jonin after this mission is over! I can earn more money in the future."

"How about it, Xiu? This is the Shadow Clone Technique, haha, usually only Jonin can master this B-rank ninjutsu!"

"As expected of my child, he loves reading even at such a young age. He will surely bring prosperity to the Furukawa family in the future..."

"Once I have more savings, I want to find a job in the medical field so I can watch Xiu grow up with peace of mind."

"What an adorable child, still feeling embarrassed at home!"

"..."

The nightmare caused Furukawa Osamu to involuntarily recall his memories of coming to this world as he woke up, and the warm images that surged up only gradually dissipated when he sat down at the dining table.

Milk, fried eggs, and sandwiches—he ate his breakfast in silence, his thoughts wandering. Suddenly, he recalled a scene from an anime from his previous life, and he chuckled to himself:

"Is this some kind of alternative 'Tsukuyomi'? A repeat of Sasuke Uchiha's experience."

After finishing breakfast alone, Osamu Furukawa began his routine summary of his "cheat codes" in his notebook. Over the past three months, he had basically clarified some of their functions:

"It has been confirmed that the only remaining capability of the XX World Nostalgic Browser Game is data collection."

"Under normal circumstances, it's impossible to collect living people? After collecting them, you'll gain some ninjutsu insights and training experience, which can quickly improve your skills."

"Collecting it will definitely enhance mental strength and increase the range of perception, but the side effects are very obvious."

"The plants that can be collected are undetermined in terms of their 'essence' components; experiments are needed?"

"What are the limits of collecting blood?"

"The essence of data collection?"

"..."

Using Chinese characters to complete his daily summary, Osamu Furukawa subconsciously twirled the pencil in his hand, trying hard to recall the anime series he had watched on Star TV and Youku in his previous life:

"I should have known better than to skip those memories!"

When I was young, I only cared about the storylines involving Naruto and Sasuke.

After starting work, I graduated from the world of anime and manga.

By the time I turned 30, I was completely addicted to electronic games and all I wanted to do was play idle games.

Still unable to glean any useful information for this particular point in time, after burning the written records, Osamu Furukawa continued to peruse the scrolls and records left at home:

Rank B - Earth Escape: Earth Flow Wall.

Rank B - Water Escape: Water Formation Wall.

Rank C - Earth Escape: Return of Earth to the Land

Rank C - Water Escape: Water Chaos Waves

Rank D - Earth Release: Heart-Slaying Decapitation Technique

In addition to these detailed records of ninjutsu, there are also insights into Lightning Release: Earth Walk, Shadow Clone Technique, Nature Transformation, and Form Transformation.

Furukawa Osamu has basically mastered the Earth Return and Water Candy Reaper, and D-rank basic ninjutsu is a piece of cake for him.

Some of the differences from the original memories indicate that commoner ninjas don't have as many techniques.

Ichiro, who seems to be qualified to be promoted to Jonin, excels more in taijutsu, shuriken, and mission performance. He has only mastered water and earth nature transformations and is more skilled in auxiliary defensive ninjutsu.

"Chakra is truly a wondrous energy!"

Although ordinary ninjas cannot store chakra, when extracted as a bodily instinct, it allows children to perform feats such as scaling walls and leaping across rooftops.

Perhaps because he absorbed the "collected results", Shuna Furukawa could clearly feel his own growth, and his body was gradually turning the experience and insights he had gained into instinctive reactions.

Tomorrow, the Ninja Academy will officially begin its term. With a grander goal in mind, Osamu Furukawa begins to formulate some plans:

"Possessing the three attributes of water, earth, and lightning, if he can successfully learn medical ninjutsu, entering Konoha Hospital might save him training time."

Before leaving, after putting on his clothes and protective gear, Furukawa Osamu looked at the photo frame again, thinking about the dreams of the past few months, and sighed softly:

"I will live a wonderful life; life shouldn't be so fragile."

-

The ninja academy is lined with blooming cherry blossoms.

The father and son, dressed in green bodysuits, who had been waiting in front of the notice board, hugged each other and cried tears of joy when they saw the name "Matt Kai" appear.

The parents who had been watching the supplementary list all took a step back when they saw this scene. Matt Daly, beaming with pride, knelt down, placed his hands on his son's shoulders, and loudly instructed him:

"Kai, the fact that you don't have a talent for ninjutsu is something to be happy about in my opinion."

"Knowing your weaknesses allows you to make your strengths shine; your physical skills are already beginning to take off!"

Seeing his father's confident smile and thumbs-up, Might Guy nodded repeatedly. Having successfully entered the Ninja Academy, the boy felt much more confident and shouted to himself:

"I'll do my best. Once I finish 500 laps around the track, I'll challenge Shu and Kakashi!"

"That's what youth is all about, Kai!"

"..."
