Immortality begins with the ninjas of Konoha.

In early December of Konoha Year 46, the loss of control of the Nine-Tails Jinchuriki sparked considerable controversy among the higher-ups, and hardliners resurfaced.

Although the Anbu immediately blocked the news, with Danzo's "help," "rumors" still circulated among the Jonin.

Perhaps driven by a thirst for war, or perhaps because Jinchūriki lack "human rights," hardliners, under the guise of "security," have once again proposed "instrumentalization."

As usual, the major ninja clans in the village remained silent in response, and the incident was eventually quelled by Jiraiya and Tsunade.

Two of the three legendary ninjas supported their teacher, Kushina's supervision was strengthened again, and developing a technique superior to the Four Symbols Sealing Technique became the village's top priority!

In the morning, at Konoha Hospital, Kushina visited Minato Namikaze under the supervision of the Anbu squad. As usual, the girl rushed into her beloved's arms early.

"Ouch, that hurts a little, Kushina!"

Minato Namikaze propped himself up on the hospital bed, looked at the girl on top of him, and complained somewhat embarrassedly.

"Where does it hurt? Lady Tsunade told me you can be discharged the day after tomorrow..."

Kushina let out a soft gasp, then began to caress Minato's body. By the end, both of them were slightly flushed, and a "pink" atmosphere suddenly filled the room.

"Looks like I've come at the worst possible time. Wait, some inspiration has suddenly struck me!"

"Using you as a model, let's try to create a poignant love story..."

Jiraiya appeared at the doorway, stroking his chin as he spoke, becoming increasingly excited as he imagined something extraordinary, his smile gradually turning lewd.

"Jiraiya! Don't stand here blocking my way!"

Tsunade muttered a complaint from behind, shoved Jiraiya aside, entered the room, sighed, and looked at Minato, saying softly:

"This is too dangerous! If it weren't for your Four Symbols Seal, this loss of control could have caused serious trouble."

"However, this is not a bad thing. Sarutobi-sensei hopes that you can perfect the sealing technique and not let everyone down."

"As for supervision, I'll have to trouble you with that, Minato. Kushina needs to minimize going out, so you can visit her more often. I don't need to tell you how to do that, right?"

Knowing that Kushina had escaped by tying up the ANBU, Minato Namikaze was worried. He wasn't naive; he knew perfectly well that his beloved had gotten into big trouble.

Tsunade's announcement of the higher-ups' decision delighted Minato Namikaze, who instinctively squeezed Kushina's soft hand and responded with a bright smile:

"I will try my best!"

"Lady Tsunade, Jiraiya-sensei, thank you for taking care of Kushina."

Seeing the smiles on his disciple's face, Jiraiya couldn't help but think of the Great Toad Sage's prophecy. He felt that Minato, like Nagato, might be a prophetic child who would guide the world.

"Speaking of which, you should thank Xiu for his surgery to heal your injuries."

"Truly impressive! Their control over chakra may have surpassed Tsunade's, and they also have unique insights into physical activation."

"Your lower abdomen has no scars whatsoever. Take off your shirt, and you're still the same handsome man you always were!"

Jiraiya's winking made Minato Namikaze smile awkwardly. People had called him effeminate back in school, and handsome men weren't his thing.

"I knew Xiu was amazing. I couldn't compare to him at all when I was his age."

"I really have to thank him for taking care of me."

Kushina blinked in her beloved's arms, recalling the scene that day. It was indeed Furukawa Osamu who led most of the surgery. Hearing Minato's modest statement, she immediately leaned close to his ear and encouraged him:

"You were amazing when you were little!"

"How should we reciprocate?"

The couple's affectionate behavior even fed the "old folks" a mouthful of "dog food" (a Chinese slang term for witnessing public displays of affection). Tsunade pouted and waved goodbye, while Jiraiya, not wanting to be a third wheel, followed, muttering to himself:

"Tsunade, it's been so long since we had a drink together, tonight..."

"I still have a lot of work to do!"

Tsunade ignored Jiraiya behind her. Recently, Furukawa had been practicing Sage Mode in Shikkotsu Forest, and the condition of the live slug made her a little worried. She felt that this sage seemed to be too enthusiastic.

-

Within the massive fault-lined cavern of the Wet Bone Forest, beneath the pale roots of the divine tree, a slug hundreds of meters in size continuously swayed its tentacles. After splitting into a human-sized clone, it curiously inquired:

"Does Lord Xiu intend to absorb this energy?"

"Revitalizing the sacred tree is not difficult for me, but after a long period of assimilation, these roots are no longer the original sacred tree."

"This is my first time converting tailed beast chakra. Fortunately, there isn't much energy, so I can help if any problems arise."

A white branch gradually appeared in the slug's body. Unlike the seemingly lifeless tree roots above, the living branch was still growing slowly.

After Furukawa Osamu took the branch, the slug split into two palm-sized clones, which climbed onto his shoulder and continued to speak in a soft, sweet voice:

"Master Xiu's conjecture should be correct. The complete divine tree can transform all energy, and the fragments also retain basic functions."

"It's just the conversion of energy, not the 'original chakra' I mentioned."

"It's alright. This has already verified our previous conjecture. Tailed beasts are indeed wondrous chakra energy entities."

As Furukawa Osamu responded with a smile, he activated his [Gather] ability. Just as he had expected, a small ball of energy emitting a red glow quickly appeared in his hand.

In the live slug's vision and senses, the branches lost their vitality, and the small amount of Nine-Tails chakra that had been converted also vanished completely:

"Lord Xiu is just like me..."

Ignoring the wriggling slug on his shoulder, Furukawa Osamu channeled the energy in his hand into his body, then closed his eyes to carefully experience it:

"Interestingly, Yin Release, representing spiritual power, creates physical form without being visible, while Yang Release, representing physical power, infuses the physical form with life energy."

"The Yin-Yang Release is truly wondrous; even tailed beasts can use this power."

The energy collected contained very little information and had no special function; it only allowed Furukawa Osamu to better utilize his mental power.

"Yin-Yang Release? It seems to be a technique developed by Hagoromo Otsutsuki. Only he knows exactly how to create tailed beasts; no one else can do it."

"Even Gamamaru, who has a deep grasp of natural energy, cannot create life using techniques."

Furukawa Osamu nodded, then formed the hand seals for the Spirit Transformation Technique. Instantly, his spiritual power transformed into a spirit body, appearing in the Hundred Hairs Seal on his forehead, which was not yet fully formed.

In the spiritual world, the accumulated Sage Chakra appears as mist, sealed in one place by the technique.

In the past, when practicing, one could not see the specific manifestation of the technique. However, at this moment, Furukawa Osamu's spiritual body could perceive that the sealing technique was connected to the cells through the meridian system.

Unlike Tsunade's development direction, Furukawa Osamu's body is absorbing Sage Chakra in the opposite direction:

"The Hundred Healings Seal is more like an evolution of sealing techniques, independent of the body's meridian system and free from the limitations of the Eight Gates chakra points."

At this moment, Furukawa Osamu fully understood the formation of this technique. When he stepped forward to touch the misty Sage Chakra, he suddenly felt that a small part of his spiritual body had disappeared:

"Interesting. Can Sage Chakra contain a spiritual body or soul? Orochimaru is indeed going to develop the Reanimation Jutsu."

After the spell was lifted, Furukawa Osamu opened his eyes, and the slug on his shoulder asked curiously again:

"Lord Xiu, did you find anything?"

"I've mastered the basics of spiritification, but I still can't separate the spirit from the body. I'm trying to resonate with the slug."

As soon as Furukawa finished speaking, he quickly formed hand seals. When his spiritual body returned to the place where the Hundred Healings Seal was formed, it immediately caused a violent fluctuation:

"How...how did you become like this?"

Completely different from her external appearance, the slug in the resonance was modeled after Tsunade and transformed into a blonde, large-breasted girl.

"Doesn't Lord Xiu like it? Humans should all like this kind of female, right?"

"..."
