This ninja in Naruto is unscientific

Chapter 86 Uzumaki Mizuki

"Throw it away."

Nishikawa Tetsu's voice was cold, devoid of any warmth.

He took out a vacuum-packed, high-calorie compressed biscuit from his ninja tool bag, tore open the packaging, and handed it to the girl.

"That steamed bun was covered in mud and blood; it was filthy. Eat this."

However, to Nishikawa Tetsu's surprise, the girl did not pounce on him like a hungry wolf.

She stared at the cookie that smelled so temptingly of milk, her throat bobbing violently, her eyes filled with longing, but she bit her lip tightly, refusing to put the cookie in her mouth.

Instead, she carefully tucked the biscuit and the dirty steamed bun in her bosom into the tattered collar of her clothes.

Then, she turned around abruptly, like a startled rabbit, ignoring her injuries, and staggered into the depths of the alley.

"Um?"

Nishikawa Tetsu raised an eyebrow slightly.

He didn't rush to catch up, but followed behind at a leisurely pace.

With his speed, this frail girl couldn't possibly escape his grasp.

The girl walked through several dark, moldy alleys and finally squeezed into a shack on the edge of the village, made of discarded fishing nets and rotten planks.

The sea breeze blew in from all directions, making the room cold, damp, and filled with a nauseating musty smell.

"Cough cough... Sister..."

A faint cough, like a kitten's meow, came from the corner of the shack.

Nishikawa Tetsu stood at the doorway and, through the gap in the tattered curtain, could see what was inside.

On a pile of blackened straw lay an even smaller girl. She looked only three or four years old, with a sickly ashen face, chapped and peeling lips, rapid and weak breathing, and barely any rise and fall of her chest.

The girl rushed to the haystack and frantically pulled out the food from her arms.

"Eat...eat quickly, there's food."

With trembling hands, she tried to break the sour steamed bun into pieces to feed her younger sister, but because she didn't hold it properly, the bun fell to the ground.

She frantically picked up the compressed biscuit that Nishikawa Tetsu had given her, broke off a small piece, and tried to stuff it into her sister's mouth.

"Swallow it...please, swallow it!"

However, the younger sister no longer had the strength to swallow.

The hard, dry cookie crumbs got stuck in her throat, which not only failed to save her life but also triggered a violent coughing fit.

"Cough cough...cough..."

The younger sister rolled her eyes, her body twitched a few times, and then she slumped down, her breath extremely weak.

Tears welled up in the girl's eyes as she looked at her dying sister, a resolute glint in her eyes.

She suddenly rolled up her tattered sleeves, revealing her arms covered in scars.

On that arm, there were two rows of neat and ferocious teeth marks.

"Bite me... quick, just bite me once..."

The girl put her arm to her sister's mouth, trying to pry open her sister's tightly closed teeth.

Just then.

A hand reached out and precisely gripped her wrist, stopping her movement.

"Stop it."

Nishikawa Tetsu had entered the shack at some point.

He first glanced at the teeth marks on the girl's arm, a look of understanding flashing in his eyes. Then he squatted down, pressed two fingers on his sister's carotid artery, and examined it carefully.

"Severe electrolyte imbalance, dehydration, and long-term malnutrition led to multiple organ failure."

Nishikawa Tetsu's voice was as calm as if he were reading out an experimental report.

"Her esophagus is probably spasming, making it impossible for her to eat solid food, or even drink water. What you're doing now is hastening her death."

"What can we do?! Please... save her!"

As if grasping at the last straw, the girl knelt down with a "thud" and clung tightly to Nishikawa Tetsu's trouser leg.

"I'll do anything to save her! Please, save her!"

"Move aside, I need to establish an intravenous access."

Nishikawa Tetsu didn't have time to heed her pleas. Instead, he quickly opened his medical kit. Every second was precious in this situation, and there was no guarantee that the little girl wouldn't make it at any moment.

He took out a sealed bag of transparent liquid—a mixture of glucose and electrolytes that he had modified according to Orochimaru's formula, originally intended as a temporary emergency supply for himself.

"illumination."

Nishikawa Tetsu said.

The girl paused for a moment, then hurriedly pulled back the tattered cloth covering the roof of the shack, letting in a ray of dim sunlight.

Using the light, Nishikawa Tetsu found a thin, almost invisible vein on the back of his sister's withered hand.

Disinfect, then insert the needle.

The movements were fluid and graceful, without any unnecessary tremors.

"The health has recovered."

Nishikawa Tetsu secured the needle with tape, adjusted the flow rate of the IV tubing, and then hung the IV bag on a pillar in the shack.

Immediately afterwards, a soft green light shone from his hands—the Palm Immortal Technique.

However, he did not directly treat his sister's organs. Instead, he carefully guided the medicine to flow through her depleted blood vessels to prevent the sudden fluid intake from overloading her heart.

"What...what is this?"

The girl stared blankly at the transparent bag, watching the dripping liquid flow into her sister's body through the tube.

"The water of life".

Nishikawa Tetsu replied calmly, "For her right now, this drop of water is more important than any food."

Ten minutes have passed.

As glucose and electrolytes entered the bloodstream, the little girl's previously ashen face finally regained a faint glimmer of color, her tightly furrowed brows slowly relaxed, and her rapid breathing became steady.

"He's alive."

Nishikawa Tetsu retracted his palm technique and wiped the sweat from his forehead.

"However, this only pulled her back from the brink of death. If she continued to live in this environment, bacterial infection would still take her life."

The girl rushed to her sister's side, feeling her faint but steady breathing, and tears streamed down her face.

In this bleak world, she witnessed a miracle for the first time.

"Thank you... thank you, sir..." She kept kowtowing, her forehead hitting the muddy ground with a loud thud.

"Don't thank me yet. As I said, I believe in equal exchange."

Nishikawa Tetsu looked down at her, his gaze falling once again on her arm covered in teeth marks.

"Physical healing... Healing injuries by biting skin to absorb chakra, you're a descendant of the Uzumaki clan, aren't you?"

The girl froze, instinctively covering her arm, her eyes filled with fear.

"Don't be afraid, I'm not interested in eating people."

Nishikawa Tetsu took a nutrient solution out of his bag and tossed it to the older girl.

"But I need an assistant, and... your physique is very valuable for research."

He glanced at the IV bag; it still contained more than half the liquid.

"Pack your things and come with me."

Nishikawa Toru looked at the sky outside, and in the distance, the sound of a ship's horn rang out again on the sea.

"The ship to the Land of Hot Springs is about to depart. There are clean rooms, medicine, and food there. If you come with me, your sister will have a chance to live."

With his current skill level, he naturally cannot cure his sister who still has one foot in the grave, but as long as he finds Lady Tsunade, the child can definitely be saved.

"Of course, in return, you'll have to work for me."

The girl paused for a moment.

She didn't know what research value was, nor did she know what the future held.

But as she looked at her sister's peaceful sleeping face, she then looked at her own arms covered in scars.

If it means selling my flesh and blood to the devil to save my sister's life, what does it matter?

"I'll go with you."

The girl wiped away her tears, her eyes hardening.

She carefully picked up her younger sister, who was receiving an IV drip, her movements as gentle as if she were holding a fragile treasure.

"Mizuki... My name is Uzumaki Mizuki."

She lowered her head, her voice hoarse yet clear.

"She is Kana Uzumaki."

"Nishikawa Toru, Konoha Chunin."

He turned and walked out of the shack, sunlight shining on his back.
