Naruto: The Ninja World's Life Buyer

Chapter 33 Suturing and Adsorption

8 PM.

The basement of the orphanage.

Tonight, there's a strong smell of grease in the air.

Several pieces of pork with skin on were laid out on the cutting board.

This was specially purchased by Nono from the slaughterhouse. The skin and meat from the pig's abdomen have the structure closest to that of the human body, with a thick layer of fat and loose skin.

Lesson Three: Stitching.

Nono was wearing a mask, only her eyes were visible.

She picked up the needle holder and clamped a hook-shaped suture needle.

"While medical ninjutsu can accelerate cell division and wound healing, chakra alone is not enough for large-area lacerations."

"If the wound is left open, and only the skin heals, a cavity will form inside, leading to fluid accumulation and suppuration."

"The key to suturing lies in 'alignment'."

"Align and fix the severed muscles, fascia, and skin layer by layer according to their original structure."

Nonou's movements were slow and steady.

The needle tip pierces the pigskin, the wrist is gently twisted, the thread is passed through, and then a knot is tied.

"The suturing methods also vary."

"Simple interrupted sutures are suitable for the skin."

"Massage sutures are suitable for wounds with high tension."

"Intradermal sutures are used to reduce scarring."

She demonstrated and explained at the same time.

Sosuke stood to the side, holding a needle holder in his hand.

His hands were very steady.

The injuries he sustained during his daytime "Double Ghosts Knocking on the Door" practice have been healed by his medical ninjutsu.

Despite the grayish-white calluses covering his fingers, his sensitivity did not decrease after being stimulated by the electric current.

Because he was used to manipulating steel wire, he had a natural sensitivity to the tension of the "wire".

"Give it a try." Nono pointed to the pork in front of her.

Sosuke picked up the needle.

This is an ordinary medical steel needle.

He first observed.

The piece of meat in front of me had been cut open with a slit about ten centimeters long, and the fat layer rolled up, like an open baby's mouth.

If suturing is required, the fat inside must be removed first.

Zongsuke took action.

The needle tip pierced through.

The resistance is significant.

Pigskin is much thicker and tougher than human skin.

Sosuke pushed hard.

puff.

The needle went through, but too much force was used, and a large hole was torn in the needle eye.

"Too rough," Nono shook her head. "Suturing should follow the skin's natural texture. What you did just now was forcefully chiseling."

Sousuke frowned.

He took a deep breath and regulated his breathing.

Killing someone involves forcefully cutting them off; saving someone involves forcefully connecting them.

These two forces, though seemingly opposite, are unified in some ways.

It all comes down to the control of structure.

He tried again.

This time, he imagined himself wiring.

Treat the skin and flesh on both sides as two fulcrums that need to be connected.

The needle is the shuttle, and the thread is the steel wire.

Insert the needle, remove the needle, and tie a knot.

This time it went much more smoothly.

But the knots that were tied were a bit crooked and twisted.

"The line is pulled too tight."

Chiba, who was in the corner, came closer again.

He stood on tiptoe, looking at the knot in the thread.

"If the thread is too tight, it will strangle the surrounding tissue, leading to ischemia and necrosis."

"If it's too loose, the wound won't close properly."

Chiba pointed to the bottom of the knot.

"Leave a little space here. Allow room for the tissue to swell and become congested."

"The wound will be swollen in the early stages of healing. If you strangle it now, the stitches will become embedded in the flesh tomorrow."

Sosuke looked at Chiba. This child's talent was simply monstrous.

"Why don't you give it a try?" Sosuke handed the syringe to Chiba.

Chiba hesitated for a moment and looked at Nonou.

After receiving tacit approval, he took the tools.

That was an adult size that didn't fit his small hands.

But he held it very firmly.

Thread the needle, draw the thread, and tie a knot.

The movements were fluid and graceful; in just over ten seconds, three perfect square knots were tied.

The tension should be moderate, and the stitch spacing should be even.

It looks like it was sewn by a machine.

"Amazing." Sosuke exclaimed sincerely.

He looked at the suture and suddenly had an idea.

"Nonou-sensei".

Sosuke took a small box out of his pocket.

"Ordinary cotton thread or catgut can be used, but it is prone to infection and is not strong enough."

"What if we use silver thread?"

"Silver thread?" Nono was taken aback.

"Silver has antibacterial properties," Sosuke explained. "And it's an inert metal, so there's little risk of rejection."

"Theoretically, it's the ideal suture thread." Nono picked up the roll of silver thread and tugged at it. "But this stuff is too expensive. Even Jonin wouldn't be willing to use silver thread to suture wounds."

Sosuke is preparing for the future.

If one's abdomen is cut open and stitched up with silver thread on the battlefield, the survival rate is greatly increased.

……

early morning.

The air at the waste treatment plant was still terrible, but Sosuke had gotten used to it.

He didn't bring the Wind Demon Shuriken today.

As Genzo said, today's training will not involve using your hands.

"You're here?"

Yuanzao pointed to the wall at the very edge of the processing plant.

It was a high concrete wall, about twenty meters high, used to prevent garbage from sliding down. Its surface was vertical, smooth, and covered with moss.

"For ninjas, the ground is only half of the battlefield."

Yuanzao took a sip of his drink and pointed to the top of his head.

"Tree trunks, walls, ceilings, even the surface of water."

"Any place to stand is a battlefield."

"In the past, when you were laying cables, you could only rely on trees on the ground as support points. That was a flat surface."

"If only you could stand on a wall, stand on the top of a tree..."

Yuanzao made a gesture of envelopment.

"Your network is three-dimensional."

"Today we're practicing wall climbing. That's also known as chakra absorption technique."

This sounds a lot like the "leaf adsorption" exercise we practiced on the first day.

But the difficulty levels are vastly different.

The leaves are so light that they can be held in place with just a tiny amount of chakra.

People are heavy.

To fix a body weighing over 100 pounds vertically to a wall requires not only a huge amount of chakra, but also extremely precise control.

Especially the soles of the feet.

That is the place with the fewest acupoints, the furthest ends of the meridians, and the thickest stratum corneum in the human body.

Releasing chakra from there is like scratching an itch through a thick blanket.

"Charge!"

Yuanzao gave the order.

"Take a running start, gather your chakra in the soles of your feet. Imagine your feet are suction cups."

Sosuke took a deep breath.

He began his running start.

The speed is getting faster and faster.

Just as he was about to reach the wall, he suddenly pushed off the ground, his body leaping into the air, his feet landing on the wall.

Chakra burst forth.

Snapped.

The first step is stable.

It felt like stepping on flat ground.

Sosuke was overjoyed and took the second step.

Snapped.

It's stable now.

But just as he took his third step...

The chakra output from the soles of my feet was slightly too high.

Bang!

The reaction force bounced his foot away.

Loss of balance.

Sosuke fell from a height of three meters, landing on his back in a pile of garbage.

"idiot."

Genzo laughed mockingly.

"That's too hard. Are you trying to kick the wall down?"

"Chakra needs to be maintained at a delicate balance. Too little, and it will slip down. Too much, and the rebound force will push you down."

"Moreover, the wall materials are different."

Yuanzao pointed to the wall.

"Some places are cement, some are moss, and some are loose bricks."

"Your feet must be as sensitive as your tongue. The instant you make contact, judge the material and adjust the amount of chakra you release."

Sosuke got up and dusted himself off.

This is much more difficult than I imagined.

In particular, he had eaten too much ninja beast meat, which resulted in his chakra being impure and difficult to control.

Although he has recently stopped consuming ninja beast meat and is undergoing chakra purification under Nono's guidance.

However, the chakra within him is still too violent overall, with plenty of explosive power but lacking in finesse.

"Again."

Sosuke adjusted his breathing.

the second time.

Five steps.

Then it slid down.

the third time.

seven steps.

This time, he stepped on a patch of moss.

With a slip of his foot, his chakra instantly became disordered, and he slid down the wall like a gecko, scraping off a layer of skin from his face on the rough surface.

"continue."

Genzo showed no mercy whatsoever.

"You're not allowed to leave until you reach the top today."

This training lasted for an entire day.

Sosuke's knee was swollen from the fall, and his elbow was scraped.

But he gradually found his rhythm.

He no longer deliberately pursues "sticking".

Instead, imagine chakra as a viscous glue.

Depending on the roughness of the wall surface, squeeze out different amounts of glue.

On the hundredth attempt.

Sosuke sprinted ten meters in one go.

He stopped on the wall.

The body is perpendicular to the ground.

This feeling of defying gravity made him dizzy, but he was mostly excited.

My field of vision has broadened.

He looked down at Genzo below.

That superior perspective made him understand the tactical value of this technique.

If we were to lay the wiring here...

A steel wire can fall from the sky and loop directly around the enemy's neck.

Don't get cocky.

Genzo shouted from below.

"Stand still. I'm going to throw a stone, dodge it."

"What?!"

Sosuke hadn't reacted yet.

Whoosh.

A stone flew over.

Sousuke instinctively tried to dodge to the side.

But he forgot that he was now standing on the wall.

With this movement, the chakra in the soles of his feet relaxed.

what--

Amidst screams, Sosuke plummeted from a height of ten meters.

Although he adjusted his posture in time during the air and used a substitution technique to replace a bag of garbage with his back, he still fell and was completely disoriented.

"Fighting on a vertical plane, the center of gravity is completely different from that on the ground."

Yuan Zao said coldly.

"On the ground, you rely on friction. On a wall, you rely on adhesion."

"We'll continue tomorrow. Not only must they be able to run, but they also need to be able to do handstands, move sideways, and even sleep on the wall."
