This ninja in Naruto is unscientific

Chapter 9 The Tree-Climbing Practice That Transmigrators Can't Escape

Five o'clock in the morning.

The sky over the Land of Rain remained a gloomy, leaden gray, with not even a sliver of dawn breaking through.

"get up!"

With a cold shout, the leg of the cot was kicked hard.

Nishikawa Tetsu opened his eyes groggily and saw Uchiha Fugaku standing fully armed in front of the bed. His dark circles seemed to be even heavier than yesterday, but his eyes were frighteningly bright.

"You have three minutes to wash up and get ready, then come with me to the woods behind the camp."

After finishing speaking, Fugaku Uchiha turned around, lifted the curtain, and walked out. His eager back view exuded a sense of "impatientness".

Minato Namikaze rubbed his messy blond hair and yawned: "Fugaku-senpai is up really early."

Nishikawa Tetsu quickly donned his ninja tools, a slight smile playing on his lips: "It's probably what I said last night that kept him awake."

……

A secluded rocky area behind the camp.

The rain was still drizzling, polishing the rocks until they were slippery and shiny.

Fugaku Uchiha stood before a massive black rock and took a deep breath. He turned to look at the two people behind him, his expression solemn as if he were performing some kind of sacred ritual.

"Nishikawa Tetsu, watch closely."

Fugaku Uchiha began to form hand seals.

This time, his hand seals were not fast; he seemed to be deliberately sensing the process of guiding the flow of chakra with each seal.

"巳－未－申－亥－午－寅".

When the last hand seal was completed, Fugaku Uchiha did not expel the chakra as usual.

His cheeks bulged slightly, but he forcibly suppressed the urge to spit it out. Following the theory proposed by Nishikawa Tetsu last night, he frantically compressed the density of chakra in his mouth and tried to change the ratio of chakra to air.

A burning, stinging sensation came from my throat; it was the strain caused by the excessive concentration of chakra.

"Fire Release: Great Fireball Technique!"

"call--"

There was none of the overwhelming, deafening roar of the past.

What spewed from Fugaku Uchiha's mouth was no longer the huge orange-red fireball several meters in diameter, but a pillar of fire only half a meter thick, but with a strange, ghostly blue color!

The blue flame, like a high-temperature laser sword, instantly pierced through the rain curtain.

"Sizzle sizzle—"

The moment the flame struck the rock, there was no explosion, only a tooth-grinding melting sound.

The hard granite was like butter that had met a hot knife; it was instantly burned through, leaving a hole a meter in diameter and seemingly bottomless.

The fracture surface resembled liquefied magma, and dark red bubbles were still rising from it.

A pungent smell permeated the air.

"This…"

Minato Namikaze's deep blue eyes widened, and he instinctively took a step back.

He could clearly feel the terrifying heat contained within that blue flame, far exceeding that of an ordinary fireball.

Fugaku Uchiha slowly exhaled a breath of hot white air, touched his slightly burned lips, and looked at the masterpiece in front of him, unable to hide the shock in his eyes.

"I only used such a small amount of chakra," Fugaku Uchiha muttered to himself.

In the past, to cause this kind of destruction, he would have needed to activate at least a B-rank Great Dragon Fire Technique, but now, he has accomplished it with just a modified C-rank Great Fireball.

He whirled around, staring intently at Nishikawa Tetsu: "This is what you meant by complete combustion?"

Nishikawa Tetsu stepped forward, squatted down beside the lava cave, observed it for a moment, and nodded:

"Although the mixing ratio isn't perfect yet, resulting in some mixed colors at the center of the flames, the temperature has already exceeded 1500 degrees. Congratulations, Fugaku-senpai, your Fire Release technique has become even stronger."

Fugaku Uchiha took a deep breath to calm his agitated emotions.

He looked at Nishikawa Tetsuya, the last trace of disdain in his eyes completely disappearing, replaced by an acknowledgment of strength—even if that strength wasn't in muscles, but in the mind.

"Now that you have proven your theory..."

Fugaku Uchiha suddenly changed the subject and said sternly, "Then it's my turn to correct your weaknesses."

He pointed to the giant trees next to him, some reaching tens of meters in height.

"I'm not worried about Minato Namikaze's talent, the main concern is you, Toru Nishikawa."

"You have a low chakra reserve, so you can't afford to waste a single bit of it. Right now, your control over chakra is too rough."

"Climbing trees."

Fugaku Uchiha gave a brief instruction: "Use your feet, not your hands, and attach chakra to the soles of your feet to climb up. This is the best way to train chakra micromanagement."

During this period, climbing trees and wading in water were not compulsory courses at the ninja academy; they were usually taught as secrets by the instructor jonin.

"learn."

Minato Namikaze nodded without hesitation, took a deep breath in front of the tree, and then charged forward.

One step, two steps, three steps...

Only after reaching the top branches of the tree did Minato Namikaze hang upside down steadily, flashing a sunny smile at those below: "Seems... not too difficult?"

"..."

Nishikawa Tetsu and Uchiha Fugaku both fell silent.

"Pervert," Nishikawa Tetsu silently muttered to himself.

This ability to achieve control in one go truly makes him a worthy candidate for the future.

Fugaku Uchiha's lips twitched slightly, then he turned to look at Toru Nishikawa, his eyes seeming to say, "See, this is what a genius is. What about you?"

Nishikawa Tetsu shrugged and walked to the tree.

Instead of rushing to rinse, he took out a small notebook and started writing and drawing in it.

"What are you doing?" Fugaku Uchiha couldn't help but ask.

"calculate."

Nishikawa Tetsu didn't even look up. "My weight is 42 kilograms, and the coefficient of friction of tree bark is about 0.6. Considering the acceleration due to gravity and the slipperiness of rainy days, the amount of chakra I need to output should be maintained at..."

"Stop calculating! Go upstairs!"

Fugaku Uchiha finally couldn't stand Nishikawa Tetsu's nagging anymore and kicked him in the butt.

Nishikawa Tetsu staggered toward the tree trunk and stepped on it.

"Smack."

The bark beneath his feet cracked, sending him flying and landing face-first in the dirt.

"Too much chakra," Fugaku Uchiha commented coldly. "You're climbing a tree, not kicking it."

Nishikawa Tetsu got up, rubbed his buttocks, and said undeterred, "I see. There is indeed a difference between the theoretical value and the actual operation. The output just now was 15% too high."

He used to laugh at Naruto and Sasuke when watching anime, but when it came to his own situation, he wasn't much better.

For the next hour.

The sounds of "smack" and "thud" coming from the woods kept coming.

Minato Namikaze sat atop a tree enjoying the view, Fugaku Uchiha stood beneath the tree with his arms crossed, overseeing the work, while Tetsu Nishikawa continuously refined his chakra output model through repeated falls and beatings.

Despite his disheveled appearance, Fugaku Uchiha's admiration grew stronger.

Because he discovered that although Nishikawa Tetsu didn't have the same intuitive and terrifying talent as Namikaze Minato, he had a very strong learning ability.

He can pinpoint the cause of every failure and never make the same mistake twice.

at last.

When Nishikawa Tetsu stood covered in mud on a ten-meter-high tree branch, looking down, he let out a long breath.

"The dynamic balance model of chakra adsorption and gravity has been completed."

"Barely acceptable."

Fugaku Uchiha snorted. Although he spoke reluctantly, he knew very well that it would take an ordinary genin at least two or three days to master this technique, while Nishikawa Tetsu had only taken an hour.

"Now that we've mastered climbing trees, the principle of treading water is the same, but before that..."

Fugaku Uchiha took out two special test strips from his ninja tool bag.

"Since Jiraiya-sama entrusted you to me, I must take full responsibility for you."

"Now that you know that climbing trees is for controlling chakra, the next step is to let you know your chakra nature so that you can develop nature transformation in advance."

He handed the test strips to the two of them.

"This is a chakra test strip. If you input chakra, it will burn if it's fire, cut if it's wind, wrinkle if it's lightning, shatter if it's earth, and become moist if it's water."

Minato Namikaze took the test strip and gently infused it with chakra.

The test strip instantly and neatly split in the middle, then wrinkled and finally burned.

"Wind, lightning, and fire attributes." Fugaku Uchiha nodded. "These attributes suit you well and allow you to develop ninjutsu with high cutting power."

Then, both of them looked at Nishikawa Tetsu.

Nishikawa Tetsu held the thin piece of paper in his hand, already having a guess in his mind.

He slowly channeled the limited chakra within his body into his fingertips.

The test strip first wrinkled violently, then became wet, and finally showed signs of cracking at the edges.

"Thunder, Water, Earth".

Fugaku Uchiha looked at this scene with some surprise; this burden also had three attributes.

"Three attributes? Although the quantity is small, the attributes are quite varied. However, is lightning the primary attribute?"

He looked at Nishikawa Tetsu thoughtfully: "Lightning Release can activate cells and increase speed, and it can also produce high penetrating power."

"If you combine your so-called science, perhaps you can take a completely different path."

Nishikawa Tetsu looked at the crumpled test paper in his hand, but a series of terms such as "electromagnetic induction," "hydrogen production by water electrolysis," and "high-voltage current trap" had already surfaced in his mind.

"It seems that my 'Scientific Ninja Tools' development plan now has an energy core."

Nishikawa Tetsuya's lips curled into a smile.
