Immortality begins with the ninjas of Konoha.

In early September, Osamu Furukawa will be turning 11, and Tsunade, as always, generously gifted him a long sword made of chakra metal in advance.

Although it's not needed right now, this weapon will be a perfect fit once Furukawa Osamu continues to grow taller.

At Konoha Hospital, the girls were chattering away early in the morning. With fewer wounded, everyone was in the mood for gossip again, and they were all "giving advice" to Shizune.

"Birthday night is the best opportunity to confess your feelings!"

"What? Confessing your feelings on your birthday is likely to get you rejected. It's better to do it a few days earlier."

"How could I refuse? Furukawa-kun is so gentle..."

"I heard from my senior that Furukawa-kun was called 'Furukawa Shura' by the Sand Village ninjas. Shura represents slaughter, right?"

"That was on the battlefield. In the hospital, Furukawa-kun was both handsome and gentle, and he always smiled when talking to everyone. No wonder Shizune always blushed and ran away..."

As Shizune heard the group's increasingly outrageous remarks, she could only angrily call them out to leave. While the group was still laughing and joking, Furukawa Osamu and Tsunade appeared outside the office door.

"It can actually increase the number of cell divisions?"

"In this way, the shortcomings of creation and regeneration can indeed be made up for."

"It's too difficult to modify cells through activation alone; I probably won't be able to master that technique."

"Are you trying to make me look foolish?"

Wearing a blue Jonin casual outfit, Tsunade turned her head and complained while holding the documents. She had left home too early and hadn't styled her hair in pigtails, making her look younger than usual.

Furukawa Osamu dodged Tsunade's attack by tilting his body to the side, took the document from her hand, and continued:

"Chakra is a kind of energy that enables communication between people. The higher the quality, the more information it carries."

"Teacher, I should be able to help you reconstruct the Hundred Healings Technique."

Finally, Furukawa whispered something to Tsunade, who nodded slightly, indicating her approval of the proposed body modification suggestions.

Seeing the two so close, Shizune subconsciously tugged at her Chunin vest. The girl felt a little disappointed; she still couldn't keep up with the genius.

"What's wrong, Mute? Don't you like this breakfast?"

Shizune only snapped out of her daze when she heard Furukawa Osamu's voice. Looking up, she saw his familiar yet unfamiliar profile and could only stammer a reply:

"I love it! I really love it... Xiu, thank you for breakfast."

Sitting in her seat, Tsunade watched Shizune run off, her face flushed, and shook her head helplessly. Once all the girls in the office had left, she muttered to herself again:

Will the Hundred Healings Technique also change one's temperament?

Furukawa Osamu stroked his chin, feigning deep thought, and finally pointed to the deep purple mark on his forehead, responding with a smile:

"It's probably because of the mark; you'll get used to it."

Tsunade didn't ask any further questions. As ninjas, everyone has their own trump cards. She just felt that Furukawa Osamu had merged with "nature," and his entire demeanor had changed drastically.

Invited to the Uchiha clan's territory that evening, Furukawa Shuichi once again drew gasps of amazement from everyone on his way there. During the banquet, even Uchiha Fugaku exclaimed in admiration.

The Uchiha youths who survived the main battle took turns expressing their gratitude. Although the Three-Colored Pill had some aftereffects, it could awaken the Sharingan, so the side effects were insignificant!

"There are sacrifices to reap greater rewards, Xiu. We've discussed this several times in the clan council and decided to relinquish part of the guard force."

"Once the war is won, the Uchiha clan will only retain the First Guard Unit."

"I hope that the elite ninjas of the clan can work in the Anbu and contribute to the Fourth Hokage!"

Perhaps because he had attended so many clan meetings, Fugaku Uchiha seemed unusually relaxed about "borrowing" his future position, tacitly assuming that Tsunade would be the Fourth Hokage.

Furukawa Osamu hadn't expected his previous suggestion to actually pass smoothly within the Uchiha clan. Seeing Fugaku Uchiha's confident expression, he whispered a reminder:

"Clan Chief Fugaku, if such a decision is made, the village's funding for the Uchiha clan will be reduced."

"Don't worry! Xiu, we hope to increase the clan's income through the herb business."

"During this time, I have also reached some agreements with the other ninja clans in the village, so I will not cause any trouble for the Hokage."

When Fugaku Uchiha talked about the plan, he looked at Osamu Furukawa with a burning gaze. The herb business still needed Tsunade's approval.

Once they control the upstream raw materials, the Uchiha clan can use their established channels to dump their products on other small countries and ninja villages.

Furukawa Osamu doesn't mind the spread of the mutated herbs, because he has always controlled the "source," and he can reap rich rewards once he authorizes it to the ninja clan.

"The problem isn't the herbs themselves, but the market for herbs will shrink once the war ends."

"Clan Chief Fugaku, there's no need to rush."

Fugaku Uchiha laughed heartily, explaining that besides making money, the herbs could also be used to develop and improve the Kyonenmaru.

After testing on the battlefield, it was found that some Uchiha ninjas' ocular power was enhanced after taking the Kyogenmaru, a discovery that brought great joy to the clan!

"As a member of the village, the Uchiha clan doesn't mind giving up some benefits."

"Xiu, you should know that we, like everyone else, have inherited the Will of Fire."

"We are willing to make changes as long as we can let go of past prejudices."

Instead of revealing the real reason, Fugaku Uchiha invoked a grand principle. As the inheritor of the Will of Fire, Osamu Furukawa naturally showed admiration upon hearing this and respectfully replied:

"With Clan Chief Fugaku around, the Sharingan will definitely appear on the Shadow Rock in the future. I'm really looking forward to that day!"

Hearty laughter frequently filled the banquet. This time, they were taking a step back to advance. Everyone in the clan believed that as long as their strength continued to grow, the Uchiha clan would eventually obtain the position of Hokage.

On September 9th, his birthday night, after returning home, Furukawa Osamu routinely activated Sage Mode. In his perception, the familiar chakra reappeared in the Uchiha clan's territory.

Unlike usual, this time the White Zetsu seemed to be demonstrating its presence, no longer using the Root Network to remain deeply hidden.

"Is White Zetsu hoping to be discovered by the Uchiha clan?"

"It seems that old guy is very confident in his abilities!"

Furukawa Osamu felt that Uchiha Madara was not only confident, but also had some misunderstanding. After careful consideration, he felt that Madara's idea was not wrong, as ordinary ninjas could not control the energy of the Divine Tree.

The slug on his shoulder gradually merged into Furukawa Shu's body. Within the Hundred Healings Seal, the spirits communicated silently:

"Lord Xiu, should we continue to devour him?"

"No, we still need to prepare for a while longer. After all, the quality of the opponent's chakra is above mine; it is the power of the Sage of Six Paths."

Sitting cross-legged on the ground, Furukawa Osamu raised his right hand and extended his index finger. With a somewhat piercing hiss, the spinning miniature chakra ball suddenly took the shape of a shuriken.

"Sage Art: Mini Spiral Shuriken!"
