Flesh Substitution Technique

"Watanabe-senpai, I haven't officially started my job at the hospital yet, right?"

"Yes, that's correct, which is exactly why I'm saying you have no authority to treat the wounded here!"

"Oh, then why don't you step aside? Since I haven't been hired yet, what right do you have to manage me? I'm a Genin who graduated from a proper Ninja Academy; I'm not in the same system as you medical ninjas. No matter how high your rank is, it doesn't apply to me."

"Baka! Kimura Takuya, is that how you speak to your senior?"

Watanabe Masa was infuriated, raising a finger to berate Kimura Takuya, but the latter ignored him entirely.

He went about his business, moving to save the patient.

"Absolutely not! This is my territory; you are not allowed to perform treatment here!"

"Damn it, you stubborn old man, are you really going to stop him from saving my captain?"

The one-armed ninja had pinned all his hopes on Kimura Takuya.

Seeing Watanabe Masa obstruct them time and again, he let out a roar, pulled out a kunai, and lunged at him.

Slap!

Kimura Takuya reached out and grabbed his wrist.

"Carry your captain outside. We don't have time to waste breath on him."

Attacking a medical ninja was a serious crime; even for a meritorious Anbu ninja, there would be no escaping the consequences.

Hearing this, the one-armed ninja immediately stood down, and the group worked together to carry the wounded man out.

Outside the emergency building, right by the roadside.

The group simply laid the man down on the curb.

"I need chakra. First, I'll stop your bleeding, then you'll give me your chakra."

Kimura Takuya didn't waste words, directly using a high-temperature Chakra Scalpel to cut into the wound on the one-armed ninja's severed limb.

"Ah!"

A wisp of blue smoke rose from the cauterized wound, accompanied by the smell of charred meat.

Kimura Takuya saw him shivering in pain, yet gritting his teeth to endure it.

A real man, he thought to himself.

Then, he raised a hand and pressed it against the man's abdomen, reversing the release method of the Rasengan. A suction force of chakra formed in his palm, drawing the one-armed ninja's chakra into his own body.

The one-armed ninja did not resist, allowing Kimura Takuya to proceed until he eventually passed out.

"I'll need a basin of hot water in a moment. Go prepare that."

The female medical ninja nodded and ran toward the hospital's hot water room.

With both of them occupied, there were still many onlookers nearby.

Among the crowd, a figure with black hair and black eyes, holding a small pig, watched with curiosity.

The nurses on duty in the emergency department wanted to help, but they were all dismissed by Watanabe Masa and had to leave, albeit reluctantly.

"Little Takuya, although I don't know what you're planning, if you need help, we sisters will assist you."

Tomiko, who had just finished her shift and changed into casual clothes, arrived alongside the night-shift nurses who were also heading home.

"That's right, Little Takuya, just say the word if you need chakra or anything else."

"Thank you, sisters. I have enough chakra now. Please, just take care of this one-armed ninja for me. I'm about to begin the surgery, and I need a dust-free environment, so I hope everyone can step back a bit."

The group nodded in agreement and moved the one-armed ninja to the side to look after him.

They wanted to see how Takuya was going to perform the treatment, but when they turned their heads, all they could see was a massive hemispherical chakra barrier.

This chakra barrier was, naturally, Kimura Takuya's defensive orb—the Spiral Protection Shield.

Hmm, he thought, I saw Rotation yesterday, so developing a budget version of a body-protection skill today seems perfectly reasonable, right?

Inside the Spiral Protection Shield, Kimura Takuya was considering a problem.

It wasn't a question of how to save him.

That wasn't an issue; the ninjutsu to save lives was called the Flesh Substitution Technique.

It was essentially using the True Transformation Technique on someone else to achieve a universal healing effect.

Although this technique was a universal medical ninjutsu capable of curing any disease or injury.

The rank of this technique should technically be an SSS-level forbidden jutsu.

After all, even when Kakashi used the Transformation Technique, he had to constantly adjust his vocal cords to match the voice of his target.

For an average person, the Transformation Technique could only achieve a certain degree of external deformation.

Or, it was relatively easier to transform into pure metal objects like shuriken.

Even the Akimichi clan could only transform into the version of themselves they were most familiar with.

Their Multi-Size Technique could only enlarge their own bodies, not transform into someone else and then enlarge them.

Otherwise, why not just transform into a Tailed Beast and spit out a Tailed Beast Bomb? Wouldn't that be better?

They simply cannot transform into things they are unfamiliar with.

Not to mention the Flesh Substitution Technique; it is not merely a transformation technique, but a True Transformation Technique.

It converts the "transformed" body parts into real ones, so they will not revert even if attacked.

The difficulty of this technique lies precisely in this; it is not just a superficial change to fool people, but a deep, authentic transformation that repairs injuries and illnesses.

What makes it even harder is performing it on someone else, as you must manipulate their body to execute the True Transformation Technique according to your will.

For the vast majority of medical ninja, this is nothing short of a fantasy.

Yet, in the eyes of Kimura Takuya, these difficulties are not issues at all; no one understands human anatomy better than he does.

Using a transformation technique on others is also a breeze for him; the problem lies solely in the issue of the true conversion.

If you want to fill a hole, you just scrape some dirt from the side to fill it in.

But the problem now is that this female ninja has no "dirt" on her.

Her body fat percentage is likely lower than Bruce Lee's; there is simply no excess fat to use for filling the hole.

Moreover, her hole is a bit too large.

Suddenly, Kimura Takuya looked below her collarbone and gestured with both hands.

There is no other way; these two are just about enough.

Losing these is still better than losing a life.

"Ninja Art: Flesh Substitution Technique!"

Kimura Takuya performed the hand seals for once, using only one hand.

His other hand was pressed firmly against the wound.

As chakra was released, the female ninja's chest grew smaller and smaller, and the wound shrank along with it.

Her organs slowly repaired themselves, and the accumulated blood in her abdominal cavity was converted into vascular tissue.

Like 3D printing, the volleyball-sized wound healed perfectly, leaving not even a single scar behind.

He dispelled the Spiral Protection Shield.

Kimura Takuya covered the female ninja with her clothes, stood up, and stretched.

The entire process was very fast.

It was so fast that the female medical ninja who went to fetch hot water had only just arrived, panting, with a basin of hot water, without even seeing the Spiral Protection Shield.

"U-um, Doctor, may I ask if we can begin now?"

"Oh, it's finished. You can clean her body now."

"Finished, clean her body!"

The female medical ninja instantly broke down in tears, walked over to her captain, and began tidying up her face.

It looked as if she were preparing a body for a funeral.

Kimura Takuya was speechless.

Such a huge hole is gone, can't you see that?

"Hey, just tidy her up a bit; she needs to get inside for a blood transfusion immediately. Can you look at the wound before you cry?"

The female medical ninja paused at his words, then incredulously lifted the clothing over the wound.

"Healed, it's actually healed."

"Incredible, incredible little Takuya, you truly didn't let us sisters down."

"Little Takuya, you're truly amazing!"

"I told you, as long as it's a job little Takuya takes on, he will complete it perfectly; he's been that kind of person since he was a child!"

"Haha, thank you for the praise, sisters, and thank you for your help. But for now, both of them still need blood transfusions."

Kimura Takuya signaled for everyone to bring the armless ninja and the female ninja into the hospital for transfusions.

The black-haired girl in the crowd looked shocked, the pig in her hands deformed by her grip.

No one understood better than her just how difficult such an injury was to treat.

Even she, Kato Shizune.

The direct disciple of the strongest medical ninja in the ninja world, Senju Tsunade.

Was shocked by the medical ninjutsu of the boy before her.

"A miracle!"

That was how the black-haired girl evaluated the medical ninjutsu of the black-haired boy.
