The Duel Between the Yellow Flash and the Sharingan

Night.

The tent was hung with damp clothes, and the air was filled with a musty smell.

"This damnable weather." Uchiha Fugaku touched his combat uniform for the next day; it was still wet.

"If they aren't dried, your joints will get cold during training tomorrow, affecting your movements." Nishikawa Tetsu was calculating the humidity. "My suggestion is to start a fire to dry them, but the tent has poor ventilation, making carbon monoxide poisoning a risk."

"No need for such trouble."

Fugaku suddenly yanked the clothes off the hanging rope and piled them in front of him.

"Watch closely. This is the precise chakra control of the Uchiha clan."

He took a deep breath and, without forming hand seals, placed his palm on the wet clothes.

A faint red chakra lit up. This was an application of Fire Release Nature Transformation—generating heat but no open flame.

"Sizzle, sizzle..."

White steam rose, and the clothes dried and warmed at a visible rate.

"Amazing!" Minato's eyes lit up, and he immediately shoved his own clothes over. "Senpai! Help me dry mine too! These wet undies have been bothering me all day!"

"Get lost!" Fugaku cursed. "I'm the young patriarch of the Uchiha, not a dryer!"

Despite his scolding, seeing Minato's expectant gaze, and Nishikawa Tetsu silently handing over his socks...

Fugaku, with a dark expression, snatched both their garments. "This is the only time! Don't expect it again!"

After several days of joint training, Nishikawa Tetsu had collected a large amount of data on Namikaze Minato.

This future Fourth Hokage, though still young, already showed glimpses of his terrifying talent.

"Minato."

Nishikawa Tetsu suddenly spoke. "During this break, there's something I want to discuss with you."

"Hm?" Namikaze Minato looked over while wiping sweat. "What is it?"

"About your combat style."

Nishikawa Tetsu took out the small notebook he always carried from his ninja pouch and flipped to the page recording Minato's data.

"Your physique is very special. Your nerve conduction speed is about 1.5 times that of an average person, meaning your reactions are extremely fast."

"And your muscle explosiveness is extremely strong, but you lack sustained endurance. This means you're not suited for prolonged positional battles or ninjutsu exchanges like Fugaku-senpai."

Uchiha Fugaku, who was nearby, raised an eyebrow. Though he didn't speak, his ears perked up.

Namikaze Minato was taken aback, then gave a wry smile. "Indeed, I'm not good at prolonged attrition battles, so I've been practicing how to manage my stamina recently."

"No, that's the wrong direction."

Nishikawa Tetsu shook his head, his tone firm. "In this world, being a jack-of-all-trades often means mediocrity. Since your talent lies in speed, you should go to extremes."

"Extremes?"

"Exactly. You should abandon large-scale ninjutsu, even large, sweeping conventional taijutsu, and focus on developing the Body Flicker Technique."

Nishikawa Tetsu pointed to Namikaze Minato's leg muscles. "Use all your chakra to enhance that momentary burst of speed, pursuing ultimate velocity."

"But if the speed is too fast, what if my dynamic vision can't keep up?"

Namikaze Minato raised a crucial question. Not everyone possessed the Sharingan. "In that extreme speed state, my vision becomes blurry, making accidents very likely."

"This leads to the second concept I wanted to discuss—dynamic vision counter-training."

Nishikawa Tetsu was clearly prepared.

He took out a handful of small stones from his bag, their surfaces painted with alternating black and white stripes.

"Fugaku-senpai!" Nishikawa Tetsu called out. "Could I trouble you to activate your Sharingan and cooperate with an experiment?"

Uchiha Fugaku snorted. He didn't know what this kid was up to, but he walked over anyway. "If you intend to use me as a target, you'd better pray your theory is useful."

"These are strobing black and white stones."

Nishikawa Tetsu explained, "I will throw these stones in irregular trajectories. Minato, you need to sprint at full speed and catch them before they hit the ground."

"And during high-speed movement, these black and white stripes will create strong afterimage interference. What you need to learn is not to 'see' with your eyes, but to perceive using your peripheral vision and chakra."

"Only by overcoming afterimages can you see the world at extreme speeds. As for Fugaku-senpai..."

Nishikawa Tetsu looked at Uchiha Fugaku, a slight smirk on his lips. "Please use a shuriken to shoot down the stones in Minato's hands. This will test if Minato's speed can fool the Sharingan's dynamic capture."

"Shoot down the stones?" Uchiha Fugaku sneered, his three-tomoe Sharingan appearing in his eyes.

"Begin!"

At Nishikawa Tetsu's command, several stones were thrown into the air.

"Whoosh!"

Namikaze Minato shot out like a golden blur.

"Ding! Ding!"

Almost simultaneously, Uchiha Fugaku's shuriken flew out.

At first, Namikaze Minato was quite flustered.

Because the speed was too fast, everything he saw was a double image, and several times he almost had his arm cut by a shuriken, even crashing directly into a tree.

"Too slow, your intentions are too obvious!" Uchiha Fugaku attacked mercilessly.

But under Nishikawa Tetsu's constant corrections, using his peripheral vision to establish spatial coordinates without looking directly at the target, Namikaze Minato's progress speed was simply outrageous.

Over the next half month.

In this clearing in the forests of the Land of Rain, a chase between golden flashes and red eyes was staged daily.

Nishikawa Tetsu, meanwhile, crawled and rolled in the mud, using that "Limit Breakthrough Method" to gradually expand his Chakra reserves.

Although the days were monotonous and painful, the gazes of the three people became sharper and sharper.

Until one evening.

"Swish!"

Nishikawa Tetsu threw a pebble.

A golden light flashed.

Namikaze Minato's figure instantly appeared ten meters away, steadily holding the pebble in his hand. And where he had originally stood, a slowly dissipating afterimage remained.

"Clang!"

Uchiha Fugaku's shuriken pierced the afterimage, but embedded itself in empty space.

"This..."

Uchiha Fugaku looked at the dissipating afterimage, the three tomoe in his eyes spinning wildly.

Just in that instant, his eyes had indeed seen Minato, but by the time his body reacted and threw the shuriken, Minato was no longer there.

You're telling me this is a Genin?

"Success."

Nishikawa Tetsu recorded the data from the side. Although covered in mud, his eyes were full of excitement: "The neural reaction delay has been compressed to 0.08 seconds."

The current Minato-senpai now possessed the qualifications to become the Yellow Flash, and at this rate, he should be able to learn the Flying Thunder God Technique sooner.

Namikaze Minato looked at his hands, the feeling of controlling extreme speed, of the world slowing down in his eyes, fascinated him.

He turned his head and gave Nishikawa Tetsu a brilliant smile: "Thank you, Tetsu! This training method is too effective!"

"Hmph."

Uchiha Fugaku put away his shuriken. Although he was somewhat displeased that his prediction had missed, the recognition in his eyes deepened.

He had to admit that these two commoners—one with a monstrous mind, the other with a monstrous body—were indeed qualified to stand beside the Uchiha.

Just then.

"Boom!"

A cloud of white smoke exploded in the center of the clearing.

A toad carrying a giant scroll descended from the sky.

"Apologies for disturbing the three of you." The toad exhaled a smoke ring, its voice deep, "Jiraiya urgently summons Team Five."

The three exchanged glances, their expressions instantly turning solemn, the relaxed atmosphere of their training gone.

They all knew what this meant.

The ordinary and monotonous special training was over; the real war was about to begin.

Uchiha Fugaku tidied his ninja pouch and leaped out first, his voice echoing in the rain.

"Let's go."
