Immortality begins with the ninjas of Konoha.

At the end of November, Minato Namikaze returned with the "sincerity" of the Land of Hot Water and the Land of Frost, and the Konoha ninjas celebrated wildly in the village.

Both Sunagakure and Kumogakure have begun to "retreat," and the war situation seems to have become very clear.

In the barbecue restaurant, Nara Shikaku saw several couples across from him encouraging each other, and he sighed repeatedly, even giving up eating the barbecue.

"What's wrong, Captain Shikaku? The mission was a complete success, and the Hokage praised you highly."

Osamu Furukawa, dressed in a Chunin blue casual outfit, poured Shikaku a drink and then asked him a question out of curiosity. Across from him, Choza Akimichi, who was eating meat with gusto, laughed upon hearing the question:

"Shikaku is getting engaged soon, it's probably pre-wedding jitters."

"Shu, thank you so much for this mission. Jinchuriki, that was really dangerous."

Akimichi Tou returned to the village and embellished Furukawa Osamu's story as the reincarnation of the First Hokage. After narrowly escaping death, this senior seemed to be letting loose.

Nara Shikaku, still sighing despite his friend's teasing, took a sip of his drink and listlessly said:

"Women are such a hassle. After I get married, I'll be living that kind of life where I'm controlled."

Yamanaka Inoichi is a year older than the two and got married last year. Hearing Shikaku start complaining again, he reluctantly changed the subject.

"The New Year is just a month away, don't relax, the war is not over."

"Although we don't know why the Cloud Village left the Land of Frost, they didn't withdraw their troops from the Land of Earth."

Nara Shikaku, having finally regained his spirits upon hearing about the war, then began to discuss the situation on the front lines in the Land of Grass:

"The Iwagakure ninjas are very troublesome. Their wide-range combined ninjutsu is well-suited for head-on combat. In addition, there are some black market ninjas. We have never been able to advance the battle line."

"Kakashi performed very well in the mission; his Lightning Release ninjutsu was a perfect counter to the enemy's Earth Release."

"However, there are some minor issues. The high casualty rate when leading the team has led to many complaints."

Furukawa Osamu hadn't been paying attention to the situation on the front lines in the Land of Grass, but he secretly noted down the "casualty rate" he heard.

The celebration was filled with joy. This was the first time Konoha had successfully defeated a small country since the start of the war, and everyone who participated in the mission felt extremely proud. At this moment, most ninjas believed that the new year would be even better.

-

After each mission, Furukawa Osamu's complexion was not good. The information contained in the energy he [collected] was too complex, and it would take some time to digest it.

In Tsunade's eyes, Furukawa Osamu was overworking his body's cells, but after a careful examination, the situation turned out to be completely different from what she had expected.

In the intensive care unit of Konoha Hospital, Tsunade carefully examined the patient before falling into deep thought. Seemingly feeling embarrassed, she glanced sideways and muttered:

"It seems you have indeed made great progress in your cultivation of immortal arts."

"I admit I misunderstood you, but you still need my permission to learn forbidden techniques."

As a reward for this mission, the Third Hokage directly opened up the Flying Thunder God Technique to Osamu Furukawa. After tasting the "benefits" brought by Minato Namikaze, the higher-ups wanted to replicate this "powerful weapon"!

Forbidden techniques have never been a problem for genius ninjas, but Tsunade has never liked Osamu Furukawa fighting on the front lines.

In addition, the initial version of the Flying Thunder God Technique was imperfect, and Tsunade had a huge psychological trauma from charging into the enemy's position, which led to some disagreements.

Lying in his hospital bed, Osamu Furukawa grasped Tsunade's right hand and brought up the topic of ninjutsu again:

"Teacher, we can work together to improve this technique. After all, it was created by the Second Hokage, and the improved version must not be inferior to Minato-kun."

"During this time, I can also help the teacher rebuild the Hundred Healings Technique. Body activation and modification can be left to me."

Tsunade nodded after a moment's thought. After her careful examination, she found that the cells in Furukawa Osamu's body had an unusually strong vitality, and she began to believe the rumors circulating in the village:

"How do you introduce natural energy into your cells? It's a bit like my grandfather's constitution."

"It's too dangerous for Sarutobi-sensei to teach forbidden techniques to a ninja your age. It seems he's been blinded by victory."

Furukawa Osamu's body is currently passively absorbing natural energy, and his spirit is using the Hundred Healings Seal technique to stably synthesize Sage Chakra, which is then fed back to the cells in his body.

Using the energy gathered as the energy source for the spirit is the only way to achieve the current perfect model.

Tsunade couldn't do that, so Osamu Furukawa planned to imitate the resonance of the live slug:

"As long as the teacher agrees, we'll know the answer soon."

"The Third Hokage was probably preparing for the upcoming war; I think it's more like he was making the worst-case scenario plan."

Tsunade sighed again after hearing Furukawa Osamu's explanation. She couldn't explain the higher-ups' thoughts; the mindset of ninjas as mere tools was deeply ingrained, and anyone could be sacrificed for the sake of a necessary victory.

"Think what you want, but you'll stay in the village until the New Year."

"It just so happens that the Uchiha brat is here too. He's been looking for you several times since he came back from the Land of Grass."

"Is the water stopped?"

Furukawa Osamu looked curious and asked a question.

Tsunade nodded, straightening his shirt as she did so. Looking at the disciple who was slightly taller than her, she teased him:

"You're very popular within the Uchiha clan, probably because we went through the battlefield of the Land of Rain together!"

"It's rare to see these guys so full of praise for a ninja. It seems you've made a deep impression on them on the battlefield."

Tsunade was very curious about what Furukawa Shuu had done on the battlefield. She had only read the battle reports and had never witnessed it herself. The "Furukawa Shura" that was circulating in Sunagakure was even more unimaginable.

Although Furukawa Osamu noticed the probing look on Tsunade's face, he didn't explain in detail, responding with a cryptic smile:

"Teacher, if you become Hokage in the future, you'll understand!"

"Don't try to show off in front of me!"

Tsunade grumbled and wanted to flick her forehead twice as a form of discipline, just like she used to, but Furukawa Osamu was a bit taller than her, so she ended up having her fingers held instead.

The nurses in the hospital could clearly sense that Tsunade's mood had improved. Tsunade paused slightly, startled by the whispers behind her. Just as she was about to think, she heard Osamu Furukawa's voice again:

"Teacher, you're slacking off again! There are so many files piled up!"

Hurriedly walking to her office seat, Tsunade stopped thinking and piled up the files, a smug look on her face as she said:

"Remember, serving your teacher is what you should do!"

In early December, the Iwagakure ninja on the front lines of the Land of Grass withdrew to the rear. When the news reached the village, the overconfident Konoha ninja began to celebrate their victory in the war!

More optimistic ninjas even began calculating "war reparations." Konoha hadn't gained much from the last war, so this time they had to carve "flesh" out of the enemy.

The Uchiha clan's territory was also affected by the village's atmosphere, and many shops followed suit with promotional activities. As the reputation improved, more and more people came to spend money there.

As Furukawa Osamu passed a dorayaki shop, he noticed that Uchiha Shisui beside him paused, so he simply walked towards the shop.

"Master Xiu, you're too kind. You should come and explore this area more often!"

The young shopkeeper, with slightly dark skin, warmly welcomed them and, upon seeing Zhishui, repeatedly praised the genius of the clan.

"Sometimes even ninjas need to confront their own desires."

"It's just some snacks, there's no need to be so hard on yourself."

After serving Shisui a cup of hot tea, Furukawa Osamu sat down by the window. Shisui, who was taking small bites of a dorayaki, immediately bowed his head in thanks, then hesitated for a moment before asking:

"Senior, do you think the Uchiha clan needs to change?"

"My father told me that the village now recognizes us more, but what I see is more lives disappearing."

"When the clan leader mobilized everyone, he said that the Uchiha were a clan full of love. Now I can't feel that at all. Everyone is thirsting for power and giving their all for these eyes."

Fugaku Uchiha sent all the young men of his clan to the battlefield for baptism, and with the help of the Three-Colored Pill, almost all of them were able to awaken the Sharingan.

The power of role models is boundless. Now, without any mobilization, those who believe they have the talent of ninjas are voluntarily going to the front lines.

"The First Guard Unit should have been strengthened! You've already made the changes."

"As for 'love,' Shisui, you should have felt it. From another perspective, the Sharingan was able to awaken because of 'love.'"

"The emotions amplified by the Kyonenmaru are indeed easy to become addicted to, and you seem to have been affected as well."

Furukawa Osamu responded calmly. Shisui opened his mouth but didn't speak. After gripping his teacup tightly, he suddenly let out a long sigh:

"I'm so sorry, senior, I was completely unaware that my emotions were being affected by the medication."

"The greater the emotional fluctuations, the more deeply the cells are squeezed. Eye power is also a manifestation of chakra, and it is more advanced, breaking free from the limitations of some acupoints and meridians."

Osamu Furukawa explained the principle of the Kyonenmaru again, looking at Shisui who was bowing his head and remaining silent, and said softly:

"You should already have two tomoe by now. It's inevitable that you would have used the Three-Colored Pill multiple times while on missions at the front lines."

Uchiha Shisui was speechless. Furukawa Osamu, seemingly seeing through his thoughts, continued:

"There's no need to worry about these things, Shisui. These are just some kinds of power."

"Power itself is neither good nor evil; it depends only on how you use it."

"Changing the mind of one's people is very difficult; rather than trying to change others, it's better to focus on one's own strength."

"When you become the next chieftain, you will be able to lead the people better, and I think that's what you should be doing."

"Clan...Clan Chief?"

Uchiha Shisui was so shocked by these words that he stammered. Furukawa Osamu nodded and calmly took a sip of tea.

"Becoming the Hokage is also an option. The more resources you have at your disposal, the less trouble you'll have with certain things."

"When you become the strongest member of the Uchiha clan, people will naturally follow your lead. This is far more useful than someone just letting their imagination run wild!"

Uchiha Shisui, filled with grievances and resentment, stared wide-eyed. He had never considered these things before. After careful thought, he asked in a low voice:

"Senior, what if there are still people who oppose my ideas by then?"

"I can't make everyone accept my ideas."

Furukawa Osamu shook his head slightly as he thought about the Uchiha clan's expanding power. He was also unsure what effect taking too much Kyogenmaru would have on the special chakra in the Uchiha brain.

Seeing Shisui's pleading expression, Furukawa Osamu finally gave his answer:

"It's very simple. If you believe you are right, use your power to show them the consequences of resistance."

"If you can't persuade them, you should know what to do in the ninja world."

Killing the opponents would naturally eliminate any objections. Uchiha Shisui had also considered this point. His face paled slightly, and after a long silence, he suddenly looked up and responded:

"I will start by changing myself."

"You're truly amazing, senior! Unlike me, I'm actually affected by drugs. Do you also want to become Hokage, senior?"

Once back to normal, Uchiha Shisui asked with a smile, and Furukawa Osamu showed a look of longing before sighing regretfully:

"I just hope that Tsunade-sensei can fulfill her dream. At our age, becoming Hokage is still too far away."

"Let's go, let me see the power of the double-tomoe Sharingan."

Having regained his cheerful disposition, Uchiha Shisui laughed heartily, paid the bill, and sighed again as he left:

"I wish my father could be as considerate of my feelings as my elders."

"The adult world is too complicated. The better I demonstrate my ninja skills, the stricter my father treats me."

"Sometimes I even feel that my father is jealous; it seems like he's using me as a tool..."

"Ah, please forgive my presumption, senior. I'm probably under the influence of the medication; I've been having all sorts of wild thoughts lately."

Furukawa Osamu's eye twitched slightly. Shisui might not be mistaken; if the Kyonenmaru was used as a pupil-enhancing drug, the Uchiha's "love" might become even more intense.

-

In mid-December, Osamu Furukawa repeatedly "checked in" at the hospital, Tsunade's apartment, the Uchiha clan's training grounds, and the shopping street.

Learning sealing techniques, improving the Flying Thunder God Technique, performing surgeries, and training alongside Tsunade, Uchiha Shisui, and others, Furukawa Osamu's life became extremely regular, and his complexion improved day by day.

This routine lifestyle increasingly puzzled the White Zetsu responsible for monitoring them, and it seemed that Madara's conjecture was flawed.

At the Iron Country peninsula base, Madara Uchiha, having heard White Zetsu's report, stared at the other party with his scarlet left eye:

"No Senju clan bloodline?"

"Just a secret technique created by Hashirama's granddaughter?"

"Yes, Lord Madara. For the past two weeks, Furukawa Osamu has been with the Uchiha genius. From my observation, he simply possesses a huge amount of chakra."

"Chakra approaching that of a Tailed Beast—that's an astonishing power!"

Upon hearing their companion's report, the White Zetsu chattered excitedly, while the Ancient White Zetsu remained kneeling before Madara, quietly awaiting instructions.

Lost in his memories, Madara Uchiha's aged face showed a look of disappointment. Hashirama hadn't been on guard; this wasn't the outcome he had hoped for.

"There's no need to waste too much energy on an ordinary ninja."

"My time is running out. I need to find a target within the Uchiha clan as soon as possible. If there is no suitable candidate, I will prepare to 'awaken' Nagato's Rinnegan."

...

After completing his Sage Mode training every night, Furukawa Osamu noticed that Hakubu was no longer watching him from afar, and a smile immediately appeared on his face:

"Slug, we can make use of that White Zetsu body now. We don't have much time left, let's start searching from the Kannabi Bridge."

"Is Lord Xiu's Flying Thunder God Technique ready?"

The slug on his shoulder asked softly, and Furukawa Osamu casually cast a spell, giving a simple reply:

"It's fine for traveling."
