Immortality begins with the ninjas of Konoha.

In early September, inside the Hokage Building, the Third Hokage, Hiruzen Sarutobi, silently watched his two old friends and disciple argue, a pipe dangling from his lips.

"The most important thing now is to repel Iwagakure. We have received intelligence that Kumogakure has already sent out squads to harass Iwagakure."

"In this situation, we can even push the battle line to the border of Iwagakure, and the Land of Grass will not stand in our way."

Mitokado Homura tried to reason with Tsunade, looking at her with a sincere expression, while Koharu Utatane beside her added impatiently:

"Tsunade, you should understand what war means!"

"Without these new drugs, the village would suffer even greater losses. In another sense, this is Konoha ninjas voluntarily helping you test these drugs."

"Get enough..."

"Bang!"

Tsunade slammed her fist into the table in front of her, shattering the other person's rambling, and then stood up with an angry expression.

Hiruzen Sarutobi finally spoke, frowning as he soothed him in a low voice:

"Tsunade, control your emotions. We're all doing this for the village."

Tsunade, her blonde hair tossing, appeared before the two advisors, placed her hands on the table, glared at them, and said in a low voice:

"What do you take those young Chunin for?!"

"I have no interest in discussing this anymore. The Konoha ninja didn't have these medicines before, and they still won the war!"

"Unless Jiraiya tells me these requirements in person, the new drug will not be available on the front lines."

Koharu and Homura were overwhelmed by Tsunade's aura and instinctively leaned back.

They were somewhat worried that an emotional Tsunade might grab their collars, which would be unseemly.

Tsunade, ultimately giving her teacher face, didn't look at the two of them again, but turned to look at Hiruzen Sarutobi, who was puffing out clouds of smoke, and complained somewhat discontentedly:

"Old man! Don't let me hear any more of this stupid advice!"

"Even in the face of a war between the four countries, the Konoha ninja would not stoop to having the village's young men test medicines."

"As long as I'm here, this kind of thing won't happen."

The two advisors fell completely silent. Danzo, who had been practically invisible in the room, squinted and said:

"Tsunade, don't underestimate the resolve of the Konoha ninja!"

"The new drug was my suggestion, and it has nothing to do with Hiruzen and the others. We can stop supplying it, but we need to mobilize more ninjas."

"As the leader of the new generation of ninjas, Osamu Furukawa should go to the front lines and contribute his strength."

"This is also what you experienced back then. Ninjas need to be tempered between life and death."

Tsunade nodded slightly. In a few days it would be Furukawa Osamu's 10th birthday, and at that age she had no reason to stop the mission.

"Let's go to the border of the Land of Rain. Where the water-style ninjutsu we've learned can be of greater use."

Danzo remained silent, but in his mind, he thought of the Uchiha clan's current location and glanced at Tsunade, pondering silently:

"So they really made contact? Has the Uchiha submitted to the Senju once again?"

"Bang..."

The door closed, Tsunade left, and the two advisors turned to their old friend and complained:

"Hiruzen, Tsunade is too domineering. This is wartime, and the medical system should also follow our orders."

"Yes, Hiruzen, we're doing this for the future of the village!"

Although Hiruzen Sarutobi was somewhat displeased, he understood his disciple's personality. Tsunade genuinely cared for the village, had inherited the will of the First Hokage, and considered Konoha her home.

Seeing that his old friend remained silent, Danzo narrowed his eyes and said in a low voice:

"There's no need to waste time on these things. Before Iwagakure and Sunagakure join forces, let's completely pull the battle lines out of the Land of Fire before the end of the year."

"The root force will be mobilized to turn the tide in one fell swoop."

Hiruzen Sarutobi then changed the subject, looking at the three people in the room and saying in a deep voice:

"The secret service will also begin to operate; it's our turn to take the initiative."

The four people in the room stopped talking about Tsunade, but the two advisors and Danzo felt a sense of crisis, realizing that they might really lose their power in the future.

At 4 a.m. on September 9th, Furukawa was routinely storing Sage Chakra. In a maximum of another year, the Hundred Healings Seal would be completely completed.

The Spirit Transformation Technique played a crucial role. Ever since Furukawa Osamu transformed the energy he had collected over the past few months into his own spirit body and integrated it into Sage Chakra, the progress accelerated once again.

"Did consciousness also exist within the original 'chakra' of the slug?"

The slug wiggled its antennae on its shoulder, and after a moment's thought, responded in a soft, sweet voice:

"I'm sorry, Master Xiu, I was too weak at the time and didn't realize I had 'consciousness'."

"During my subsequent cultivation, I awakened a talent that, if it had any 'consciousness,' might have been devoured by me."

"Consciousness should also be a kind of energy. The Hashirama Senju cells that Master Shu has been researching recently are special and seem to have mutated."

Furukawa Osamu nodded. Orochimaru's research direction was correct; he had already achieved the ability to carry consciousness with Sage Chakra.

There is a so-called "consciousness" in Hashirama cells, which Furukawa Osamu believes may be caused by "Ashura Chakra," but he currently has no way to experimentally prove it.

Thinking of Orochimaru's teachings, Furukawa Osamu sighed helplessly. He was willing to call Orochimaru's "talk-no-jutsu" the strongest for the time being!

Aside from his different "Will of Fire," Orochimaru's understanding of ninjutsu was outstanding, and Furukawa Osamu benefited greatly from his mastery of Wind Release and Earth Release.

"After sensing natural energy, the body should undergo a rapid transformation, becoming a living slug. After that, I'll need your help!"

Furukawa Osamu clenched his fist, a surge of power emanating from his body. Even without using escape techniques, he was confident he could slaughter ordinary Jonin with his superior chakra and swordsmanship.

"Leave it to me, Master Xiu!"

The live slug enjoys resonating with its own kind, a rare experience in its long life.

...

Due to the tense situation, although Furukawa Osamu's classmates were not deployed to the front lines, they were busy with low-level missions during this period.

At Konoha Hospital, every ninja who sees Furukawa Osamu offers him their blessings. Nohara Rin has been working there for some time and has received care from them. On her birthday, she didn't forget to return the favor.

"Xiu, this is my improved medical kit! I hope it will be helpful during your mission!"

Nohara Rin's face lit up with a bright smile. After presenting the gift, she tilted her head and joked:

"I've been preparing this silent gift for a long time!"

Jingyin fidgeted at her desk, finally blushing as she pulled out a scarf with somewhat rough stitches and said shyly in a low voice:

"I tried my best, but I may lack the talent in this area, and I look a bit ugly."

Furukawa Osamu wrapped the red scarf around his neck, looked him over carefully, and then gave him a gentle smile, offering encouragement:

"It's so pretty! The weather will get colder soon, so it'll come in handy. I'll cherish it..."

Before Furukawa could finish speaking, Shizune ran away, her face flushed, and secretly glanced at the other red scarf, her heart leaping with joy:

"Yay! Matching outfits achieved!"
