Immortality begins with the ninjas of Konoha.

In early June of Konoha Year 48, it seemed that the Land of Rain had entered the rainy season again.

The war between major powers and the harsh environment plunged the Land of Rain into turmoil once again, and an organization called "Akatsuki" rose to prominence in this context.

Many Rain Village ninjas spontaneously joined Akatsuki, as the young people did not want to see their homeland fall and become a vassal state of a great power.

Unfortunately, no matter how lofty Akatsuki's ideals were, they could not change the cruel reality.

The conflict between Sunagakure and Konoha has never ceased, with both sides ignoring the demands of smaller nations.

In just over a month, the young ninjas of Konoha had fully adapted to the battlefield, gradually turning the killing techniques they had learned into their physical instincts.

Skilled ninjas even begin to enjoy killing; the thrill of taking lives drives them mad. This thrill, combined with the remarkable effects of the Three-Colored Pill, amplifies their emotions even further.

The rapid growth of the Uchiha "seedlings" made Fugaku Uchiha extremely happy!

Fugaku Uchiha always took the lead in every mission, guiding these elite clansmen to hone their skills.

The Uchiha clan's fierce fighting on the battlefield earned them unanimous praise from other ninja clans. Even the Yamanaka clan ninjas from the Hokage faction would speak highly of their recent battles.

"Clan Chief Fugaku's Will of Fire is astonishing; he truly deserves the name 'Fugaku the Fierce-Eyed'!"

For ninjas who crave power, slaughter is the best nourishment. A ceasefire is impossible; the war will only officially end when one side falls and admits defeat.

Osamu Furukawa has been working hard to digest the results of the [gathering], and as long as Rasa doesn't appear, he spends most of his time by Orochimaru's side.

Within the Hundred Healings Seal, the spirit body infused with Sage Chakra seems to be nearing its limit, and Furukawa Osamu is unsure what will happen after the two merge.

Fortunately, there are no shortage of opportunities to collect data during wartime. Furukawa Osamu waited patiently and recorded the experimental data along the way.

Orochimaru, meanwhile, was looking for his next target; his experiments required more ninjas with bloodline limits.

In the dead of night, in a hidden laboratory beneath the Land of Rain, Yekura, who had regained consciousness, still wore the same look of hatred on her face:

"The disappearance of the Third Kazekage was indeed related to you. What exactly did you do to my body?"

"If the Konoha ninjas hadn't stolen our commission, there would never have been a war."

"Do you know how many people will die if the agreement is broken?"

Ye Cang lay on the experimental table, her long, dark green hair spread out. Unable to control her body, she could only look at the dark stone wall above her and angrily question it.

Osamu Furukawa ignored these questions; the equipment here was somewhat outdated and unable to observe the interactions between cells.

"You evil Konoha brat, what are you doing?!"

Yekura noticed that her clothes on her shoulder had been cut open and immediately screamed. After Furukawa Osamu gave the bloodline limit ninja a sedative, he calmly explained:

"Your shoulder has been eroded, which means that the cells in your body are 'collapsed'."

"If you want to live, try to control this power and make it a part of your body."

"If you can't do these things, you'll eventually become a puppet with a chaotic mind."

Yekura didn't even have the strength to shout anymore. A skilled ninja, unafraid of death, still managed to question:

"Is it because of my bloodline limit that you sabotaged this negotiation?"

"What do you take ninjas for?"

"Sunagakure is only using you, a scorching-style ninja, as a tool. Why isn't it Rasa who's here to negotiate?"

Furukawa Osamu smiled and asked in return, then, seeing that Yekura was unable to speak due to the effects of the drugs, he sighed and continued:

"The high-ranking officials of Sunagakure are well aware that negotiations will not succeed, the entrustment will remain unresolved, and the income of many Sunagakure ninjas will continue to decrease."

"The disappearance or injury of a bloodline limit ninja and the subsequent outbreak of war can solve this problem perfectly."

"Rasa probably doesn't like you, a companion who pursues peace."

Yekura could only express her opposition with her eyes. She believed that the village would not treat her like that; Sunagakure was her home.

A chilling laugh echoed in the laboratory. When the pale-faced Orochimaru appeared before the two, only fear remained in Yekura's eyes.

"Xiu, there's no need to explain this to her. If she survives, she'll thank me in the end for granting her her freedom!"

"Scorch Release is an interesting power, but it seems that this chakra is still unable to achieve our goal."

Orochimaru, dressed in Konoha Jonin combat uniform, showed a hint of disappointment at the end of his speech. Despite both being Kekkei Genkai, the First Hokage's power, even after being weakened, was still ridiculously strong.

"Orochimaru-sensei, the bloodline limit ninja should be the upper limit of materials."

"The legendary bloodline limit is currently only mastered by the Tsuchikage, Onoki, in the ninja world."

Furukawa Osamu spoke up to remind him, and Orochimaru nodded with a smile. The two stopped paying attention to Yekura and continued their hushed discussion as they walked toward the laboratory door:

"So I want to start with a special body. If someone can accept all foreign cells and work with your research results, there is a high probability that they can master this power."

"Orochimaru-sensei, you can also try using Tailed Beast Chakra. It is said that Sunagakure's Magnet Release was developed based on this."

"It's very difficult, but it's definitely an idea worth trying..."

As their voices faded into the distance, Yekura on the experimental table was utterly desperate, and the words of Furukawa Osamu began to echo in her mind:

Am I just a tool?

-

Osamu Furukawa discovered an interesting phenomenon through his experiments with the bloodline limit of escape techniques:

"Chakra causes bodily mutations; chakra creates everything."

Although both Pakura and ordinary ninjas refine fire-style chakra, their cells differ, with Pakura's cells appearing to have undergone some mutations.

The special bloodline limit cannot be "collected," and Furukawa Osamu speculates that the energy intensity of the "collected" energy is insufficient to trigger a mutation.

The best way to pursue these powers is to trace them back to their source. Furukawa Osamu is preparing more and more actively. He needs the chakra of Indra and Ashura to verify his conjecture.

During the daily routine patrol, the perceptive Uchiha Shisui seemed to sense Furukawa Osamu's excited mood and suddenly asked in a low voice upon returning to the camp:

"Lord Xiu, why must people always fight each other?"

"I couldn't feel the glory that the clan leader described. If you can only awaken the Sharingan by witnessing the death of your comrades, it feels more like a curse of the Uchiha clan."

Most of the Konoha ninjas in the camp were laughing and talking about the results of their killings. The feeling of controlling life was addictive, but Uchiha Shisui just thought everyone had gone mad.

"Zhi Shui, war is just one way to resolve conflicts of interest."

"It's difficult for people to understand each other, but your wish for peace might be fulfilled, after all, we possess the power of chakra!"

Uchiha Shisui didn't understand what Furukawa Osamu meant by "chakra." After using the Three-Colored Pill several times in succession, his emotions became extremely sensitive.

"I want to create a world where people understand each other."
