Immortality begins with the ninjas of Konoha.

In the dark, enormous cave, the emaciated Uchiha Madara lowered his head, his long white hair obscuring his aged face.

Madara Uchiha had been keeping a close eye on Nagato's movements, as Nagato was the most crucial piece in his plan.

"Nagato is as naive as ever. If this continues, it will be difficult for him to carry out Lord Madara's plan."

As soon as White Zetsu, who was kneeling on the ground, finished speaking, his companion beside him chuckled and exclaimed:

"They actually exchanged their mission rewards for supplies and gave them away to the people of the Rain Kingdom for free. What kind of kind-hearted kids they are."

"You need to eat food to produce stool, I really want to experience that..."

The serious atmosphere suddenly broke down as several White Zetsu argued about "the feeling of pooping" in front of Madara Uchiha, until another White Zetsu fell from the branch of the Gedo Mazo above, stopping them from talking.

"Lord Madara, this is the latest intelligence from the front lines in the Land of Rain. The young man who inherited the Senju clan's legacy has mastered a form of black lightning release."

"The power of the black lightning release is astonishing; even defensive ninjutsu like the Machine Light Shield Seal cannot withstand it."

"The Sand Village's top combat force cannot return to the battlefield for a short time, but they seem to have created a new toxin, which has caused considerable trouble for the Konoha ninja."

As the White Zetsu solemnly reported on the battle that had taken place during the day, Madara Uchiha turned around completely and whispered in a hoarse voice:

"Black lightning?"

"He's actually mastered Lightning Release ninjutsu to this extent?"

"I remember seeing information about him not long ago. He's a disciple of Hashirama's granddaughter? His water-style ninjutsu is also exceptional."

"11 years old? It's a pity he doesn't have the bloodline of the Uchiha or Senju clans, so he's destined to never master true power."

"I remember now, Osamu Furukawa, did he also inherit the Will of Fire?"

The surrounding White Zetsu looked on with curiosity, all turning to their newly arrived kin. The latter, upon hearing the question, didn't mince words and answered seriously:

"Osamu Furukawa inherited the Will of Fire, values ​​his comrades highly, and is a kind-hearted boy."

"Instead of pursuing them when they had the upper hand, they went to rescue their own men."

"His medical ninjutsu was also outstanding, and he quickly brought the spread of toxins in the wounded's body under control."

White Zetsu infiltrated the body of a Konoha ninja and observed the entire process in detail. Furukawa Osamu's medical ninjutsu also left a very deep impression on him.

Madara Uchiha chuckled softly upon hearing the White Zetsu's assessment, then gasped for breath, raising his head to look at the White Zetsu with his scarlet left eye:

"kindness?"

"Do not make hasty judgments about these ninjas who possess the Will of Fire."

"He simply made the right choice. If he had pursued the Sand Village ninja, it would have been difficult to capture Chiyo in the end."

"His power is insignificant in the face of the Rinnegan, but a Konoha ninja with such talent is still an obstacle."

"I would have killed this genius if I had the chance. It's a pity that Tobirama Senju is no longer here. I really wish he could have seen this."

Madara Uchiha chuckled again, then gasped for breath. Emotional fluctuations always cause problems for the body, and his life was nearing its end.

"Lord Madara, why not modify such a genius ninja?"

"Among the Uchiha clan ninjas now, there is probably no one who can compare to Osamu Furukawa."

White Zetsu had been searching for a "supervisor," and some of the ninjas he captured during that time were no match for Furukawa Osamu. He was able to defeat a bloodline limit ninja before he was even 11 years old, so his strength met the requirements.

Madara Uchiha seemed to have heard a joke, and began to chuckle nervously again:

"The ninjas who inherit the will of the Senju clan have no idea what true love is!"

"Unable to understand the true meaning of love, unable to comprehend its true power."

"How can someone like that carry out my grand plan?"

The White Zetsu looked on with confusion, not understanding what their creator was talking about.

Madara Uchiha didn't care about the emotions of these tools. At this moment, he entered a state of self-indulgence, recalling past events and continuing to talk to himself:

"Hashirama, I'm sure I'll win this time."

"I want to create a world where only love exists!"

"There, we will meet again..."

The White Zetsu knew immediately upon hearing "Hashirama" that the White Zetsu were reminiscing about the past. Since their creation, the word they heard most often was "Hashirama."

Madara Uchiha muttered to himself, saying a lot of incomprehensible words. It took him a while to completely control his emotions before he looked at the White Zetsu and gave them instructions again:

"Now that the war in the Land of Rain has temporarily stopped, let's continue to observe the Uchiha clan."

"In the face of the true power of the Uchiha clan, even so-called genius ninjas can only look up in awe."

"Yes, Lord Madara, I will also complete the possession of Furukawa Osamu when I have the opportunity."

In early July, news of Chiyo, a high-ranking advisor of Sunagakure, being injured and Rasa, a Jonin, spread throughout the ninja world, and the name of Osamu Furukawa began to circulate among ninjas from various countries.

The Sand Village leadership has repeatedly stated that the Konoha ninja suffered even greater losses in the previous battles, but the morale of the Sand Village ninjas has still plummeted, and this time the losses are simply too great.

Hundreds of Sand Village ninja died in direct combat, and dozens more died during the retreat from their own poisonous fog.

The battle lines don't lie; the main force has already withdrawn from the Land of Rain. The Sand Village ninjas, fearing a surprise attack from a Konoha squad, simply decided to hold their own border.

Orochimaru, who was so engrossed in his experiments that he couldn't extricate himself, not only praised his subordinates, including Osamu Furukawa, but also applied to the higher-ups for a rotation.

The Root ninjas have found the "materials," and Orochimaru has to go back and meet with Danzo.

Osamu Furukawa has recently been "extremely exhausted," and his face is pale. Seeing this, the Konoha ninja on the front lines petitioned to "let Lord Furukawa return to the rear to rest," and many young men shed tears in response...

The Third Hokage, Hiruzen Sarutobi, was in high spirits after seeing the battle report. Upon learning that the new poison from Sunagakure was extremely troublesome, he decided to allocate funds to the medical department once again.

During the Jonin meeting, Hiruzen Sarutobi didn't hold back his praise, showering his disciple with compliments.

It wasn't until Tsunade made a couple of disapproving remarks that Hiruzen Sarutobi finally approved Orochimaru's application with a smile.

In the evening, on their way back to the village, the group took a short rest and replenished their food.

The short, chubby little green snake grew longer and coiled around Furukawa Osamu. Orochimaru, seeing this, grinned and said:

"It's not too late to switch to the immortal techniques of Ryuchi Cave. Xiu, these little guys really like you."

Orochimaru sometimes uses persuasive talk like he's coaxing a child, something Furukawa Osamu is used to. He subtly changes the subject, poking at the campfire and asking in a low voice:

"Teacher, have you found any new materials?"

"You noticed. I need to verify this. Once the rejection reaction is resolved, our experiment will enter a completely new phase."

Orochimaru's lips curled into a slight smile; even a portion of Hashirama's cells possessed considerable power.

Furukawa Osamu sighed in admiration, his expression now one of reverence. He was pleased to see his teacher using his modified Hashirama cells.

"Live [collection], teacher, ultimately, power must be in your own hands."
