Naruto: The Ninja World's Life Buyer

Chapter 29 Human Structure and Neural Response

After Takaya Jiro left, Sousuke took out the book that Nonou had given him from his pocket.

"Fundamentals of Human Meridian and Muscle Anatomy"

This is a handwritten copy, densely filled with notes and many hand-drawn anatomical diagrams.

Sosuke spread the book out on the table and read it with great interest.

The value of this notebook lies not only in its ability to cure diseases and save lives.

This is an excellent "slaughter guide" for a wire-wielding killer.

"The Achilles tendon, located between the heel and the lower leg, bears all the tension during walking and running. Once severed, the person loses the ability to move."

"The brachial artery, located on the inner side of the upper arm. If severed, it will cause hemorrhagic shock within three minutes."

"The vagus nerve is located on the side of the neck. A severe blow to it can cause cardiac arrest."

Sosuke looked at it and then gestured to his own body.

His fingers traced his neck, wrists, and ankles.

Previously, when Yuanzhao taught him wiring, he used geometry to enclose space.

Now, he has a new understanding.

It's not just about sealing off space, but about placing the steel wire along the path the enemy must take to dissect their structure.

Humans are sophisticated machines.

If you're going to swing a knife, your biceps will inevitably contract, and your armpits will inevitably be exposed.

If you try to run away, your Achilles tendon will inevitably tighten.

If just a few key parts are damaged, this machine will stop instantly.

If you put a wire around an enemy's outer thigh, it will only cause a superficial wound.

If you move it slightly inward by three inches, it will pierce the femoral artery.

Three seconds.

In just three seconds, the high-pressure jet of blood will knock the enemy into shock.

Sosuke closed his eyes.

He simulated it in his mind.

That invisible steel wire is no longer blindly entangled.

Instead, it acts like a scalpel, precisely cutting into soft tissues that lack bone protection.

Underarm.

The back of the knee.

throat.

This is a perfect combination of murder techniques and medicine.

Sosuke didn't sleep that night.

He memorized the anatomy book.

It's not just about memorizing words, but about engraving that three-dimensional structure into your brain.

early morning.

Waste treatment plant.

Genzo looked at Sousuke.

"Your eyes have changed."

He keenly sensed the difference.

In the past, when Sosuke judged people, he looked at them as a whole.

Now, when Sosuke looks at people, it's like he's looking at a bunch of walking chunks of flesh and bones.

That gaze carried a surgical scrutiny.

I learned something new.

Sosuke pulled out a roll of wire.

"I want to try it out in real combat today."

"A real fight?" Genzo scoffed. "You want to fight me?"

"I wouldn't dare," Sosuke said, wrapping the wire around his finger. "I just wanted to verify the theory of 'anatomical wiring'."

"Quite the boast."

Genzo threw away the wine bottle, picked up a rusty iron pipe, and stood on one leg.

"Come on. I won't use ninjutsu, only taijutsu. If you can touch my clothes with your thread, you win. I can do something for you."

"If you lose..."

"Tuition fees will double from now on."

"make a deal."

Sosuke took a deep breath.

Whoosh.

He made his move.

He threw a shuriken.

"Too straightforward."

Genzo simply sidestepped and dodged the shuriken.

However, the moment the shuriken hit the ground, Sousuke's fingers twitched violently.

The steel wire is not taut.

Instead, it coiled up on the ground like a snake.

Sosuke's target wasn't Genzo, but rather Genzo's iron crutch.

When Yuanzao wanted to move the iron crutch to adjust his center of gravity.

The steel wire got caught right at the bottom of the crutch.

"rise!"

Zongsuke shouted and yanked with both hands.

The steel wire tightened instantly, forming an extremely tricky angle that cut straight into the ankle of the only one Yuanzao had.

The location of the Achilles tendon!

The source of pupil constriction.

That kid is so insidious.

By binding his iron crutch with steel wire, not only was his movement restricted, but the crutch could also be used as a fulcrum to aim at his vital points and make cuts.

For an ordinary person, this would definitely rupture their Achilles tendon.

But Genzo is a Chunin.

He suddenly exerted force with one leg, and his whole body leaped into the air.

He escaped being cut in the ankle.

"It's not over yet."

Zongsuke's eyes were calm.

The instant Genzo jumped, he threw two more shuriken.

This time, it was a prediction of where the source would land.

It was also a prediction that he would be unable to gain leverage in the air.

Two steel wires crossed in the air.

It was positioned exactly at the height of Yuanzao's neck.

Location of the vagus nerve and carotid artery!

"Good lad!"

Genzo shouted loudly in the air.

He had nowhere to hide.

But he still had an iron pipe in his hand.

when!

Sparks flew everywhere.

The iron pipe struck precisely at the intersection of the two steel wires.

The immense force was transmitted back along the steel wire.

Sosuke felt a jolt in his hand and almost dropped it.

Source creation landed.

He glanced at the iron pipe in his hand.

There are two deep marks on it.

If that were his neck, he would be bleeding profusely by now.

Genzo threw away the iron pipe, and his gaze toward Sosuke became more serious.

How did you predict I would jump?

"Because that's your only point of support," Sosuke said calmly. "If you don't jump, your Achilles tendon will rupture. It's a natural reaction of the human body's structure."

"very good."

Genzo nodded.

"You've finally started using your brain to kill people."

"However," Yuanzao changed the subject, "your reaction speed is too slow."

"Your eyes can keep up, but your body can't."

Genzo retrieved his iron crutch. In that brief exchange, although Sosuke's setup was ingenious, he was 0.5 seconds too slow in the final closing of the net.

That insignificant 0.5 seconds was enough for an experienced Chunin to slip out of the encirclement and slit the throat of the wireman.

"How do we train?" Sosuke asked.

"The inability to train is due to a problem with neural transmission."

Yuanzhao pointed to his head and then to his toes.

"The brain sends a command, and the electrical current travels along the spine to the limbs to produce a response, which takes time. For the average person, this time is about 0.2 to 0.3 seconds."

"A ninja with superb taijutsu skills can shorten the time to 0.1 seconds through millions of muscle memory repetitions."

"And those ninjas who possess Lightning Release Chakra Mode, such as those barbarians from Kumogakure, can directly stimulate their nerves with lightning, compressing the time to less than 0.05 seconds."

"Can't you learn it without Lightning Release?" Sosuke was unwilling to accept it.

"There's a shortcut," Genzo glanced at him, "but that falls under the category of forbidden techniques. It involves forcibly stimulating the nerves with external force. You either need to find a medical ninja of Tsunade's caliber to perform surgery on you and reshape your neural circuits; or..."

"What do you want?"

"Either use drugs and equipment, treat yourself as a guinea pig, and give yourself electric shocks day after day."

Genzo sneered.

"However, it could easily lead to paralysis. Nerves are very fragile; once they're burned, they can't be reattached."

Sosuke thought of those ten pounds of lightning eels.

It turned out to be the case.

That's why this kind of meat is so expensive.

"I know what to do."

……

After finishing training, Sosuke returned to the warehouse.

He locked the door.

I took out the eel I bought last time. I've already eaten half of it, and there are still five pounds left.

He cut off a piece of meat.

This time, he cut them bigger than usual.

It weighs about one pound.

Swallow raw.

The meat went down my throat like swallowing a clump of thorny brambles.

An electric current surged through the esophagus.

My tongue is numb, my lips are numb, and even my scalp is tingling.

"Well……"

Sosuke trembled all over.

He could feel that subtle bio-current was frantically stimulating his nerve synapses.

The transmission speed of nerve signals is essentially an electrical signal.

To make the reaction faster, the "wire" needs to be thicker and have lower resistance.

excruciating pain.

This is a different kind of pain than a laceration.

It feels like countless needles are pricking your nerve endings.

Sosuke's hands twitched uncontrollably.

But he forced himself to form the hand seals.

"Wei-Hai-Chou..."

The fingers trembled as they struggled to complete the movement.

He is using this current to activate those normally dormant neural reflex arcs.

An hour later.

Sosuke collapsed to the ground.

He was drenched in sweat, as if he had just been pulled out of the water.

But the world he saw had changed.

A fly flew by.

Previously, he could only see a black afterimage.

Now, he can see the trajectory of the fly's wing vibrations.

While it can't yet achieve a slow-motion replay like the Sharingan, at least it's no longer a blurry mess.

"Is this the principle behind Lightning Release ninjutsu?"

Sosuke clenched his fist.

Of course, the improvement he gained by eating meat was negligible and could not be compared with the secret techniques of the Hidden Cloud Village.

But for him now, this improvement is already quite remarkable.

He picked up a shuriken.

Just toss it aside.

The moment the sword left his hand, the fly flew right along its trajectory.

puff.

The fly was cut in half.

"Accuracy has improved."

Sosuke's lips curled up in a smile.

The increased speed of neural reaction means a significant increase in the precision of his muscle control.

He can more accurately correct minute errors in the throw.
