414. Uzumaki ONE-Punch

Cough… cough…

Naruto coughs slightly and wipes the dust from his clothes as he jumps out of a small crater.

"Naruto, are you alright?" Minato turns to him as he aids the rest of the Kages in their battle.

His clothes are tattered from the fight, but there is not as much as a scratch on his body.

"I am fine!" Naruto cracks his head.

GWAAH…

Fu, in her second-tailed-beast transformation jumps also jumps out from the debris. The chakra cloak around her body flickers like flames. The damage on her body regenerates as a perk of being an Edo.

She releases a roar and charges toward Naruto. A portion of her head turns into the seven-tails. A protrusion resembling the horn of a rhinoceros beetle sprouts from her head. Fu spits out chakra threads from her mouth. The chakra threads wrap around the horn and harden it even further.

"NARUTO! Avoid that attack at all costs." Kurama warns him.

"Huh! Why?"

"Naruto, my seventh sibling, Chomei, is armored kabutomushi (rhinoceros beetle). The armor on its body is even harder and more durable than diamond, especially the horn, which can even shatter the most durable mineral of the shinobi world into dust. Chomei's Spear Attack Shining Horn will grind your bones to dust if you are hit by that attack." Kurama warns Naruto.

"That sounds troublesome, but I think I can fight it." Naruto clenches his fist in confidence.

A red glow gathers around his fist.

"That glow! Naruto, don't tell me, you…"

"Yes, it took me a few years, but I think I can use it now. The super powerful technique Izuna Nii-san taught me." Naruto brims with confidence.

"Also, it's almost time."

SHOOM…

A large amount of Nature energy flows into Naruto's body out of nowhere. A dark red cloak with a black flame pattern shrouds Naruto and orange pigmentation appears around his eyes.

"Looks like it was a wise decision to leave a shadow clone behind to gather Nature energy." Kurama is surprised by Naruto's wits.

'Even though Naruto isn't as sharp as Minato, his combat sense is greater than Minato.' Kurama praises Naruto in his heart.

"Alright!"

Naruto takes a deep breath and extends his right leg forward while pushing his left leg backward.

SHOOM…

He infuses his chakra and nature energy into his fist and stretches it backward. The red color chakra on Naruto's fist turns golden as a result of nature energy.

'I can feel strength brimming through my body.' Naruto clenches his fist and patiently waits for the Edo Jinchuriki to close the gap.

When Chomei's horn is just a meter away from him, Naruto finally takes action.

HAAA…

He inserts the entire strength of his body into his fist.

Bang…

The powerful reactive force from coalescing his strength forms web-like cracks beneath Naruto's feet.

"Eat this!"

BAANNNGGG…

His punch lands on Chomei's horn and creates a powerful wind current. The powerful force of the attack sends shockwaves into the surrounding with Naruto as the epicenter. Ground crumbles beneath Naruto's feet and forms a massive crater.

HAAAAAA…

Naruto yells his lungs out and pumps all of his strength in the attack.

CRACK…

Cracks appear on Chomei's hardened horn.

Bang…

With a loud noise, the horn shatters into fragments and scatters. Naruto's punch continues with its powerful momentum and lands on Fu's head.

BOOM…

The powerful impact blasts away Fu's upper body. The remaining lower body of Fu is sent flying by the punch. It crashes through several trees and buildings while leaving behind a trail of destruction.

BANG…

It eventually slams into the nearby hill. Web-like cracks appear at the point of impact, and the entire hill trembles slightly. An avalanche of ice falls down from the peak of the hill.

The shockwaves from the attack travel across the battlefield. Some of the weaker shinobis tumble on the ground as a result.

Even Tsunade, Minato, Mei, and the rest of the Kage, including Obito, momentarily pause their battle and stare at the incredulous sight of Naruto's punch.

White smoke rises from Naruto's fist as the latter stares at his fist in disbelief.

"Did I just do that?" Naruto asks Kurama to confirm his doubt.

"Yes, you finally did it!"

"What was that, Naruto?" Tsunade is the first person to question him.

"Umm… well… I… umm… how I explain it? It's my new technique!" Naruto stutters as he replies.

"Where did you learn this technique?" Minato questions him in shock, as his mind is in turmoil.

'That wasn't a normal chakra-enhancing technique used by Tsunade-sama. Instead, Naruto compressed almost the entire chakra of his body, which is almost ten times that of a regular shinobi in his right hand, and released it all in that punch.

The power and concept behind that punch are similar to a super-powerful compressed chakra cannon. The force at the point of impact is enough to shatter mountains. This Naruto, when did he…'

*******Flashback-No-Jutsu*******

"Hey, Nii-san? Teach me this cool new jutsu. I also want to blow my opponents away."

Naruto is amazed by Izuna's recent battle where the latter just punched the air and send a group of shinobis flying from a distance of almost fifty meters.

There was no wind chakra involved in that attack. If it was there, then he would be able to sense it due to his affinity with the wind.

'Umm… how do I tell him? It's not some cool technique. I just pushed my physical strength to the limit by gathering all my chakra in my arm and layering it with Sage mode and power cloak to further enhance my strength to the extreme. With such a massive boost in physical strength, I punched the air in front of me. This powerful punch compressed all the air particles in front of my fist and ejected them forward at supersonic speed like an air cannon. Those shinobis were hit by that air blast. I adjusted my strength to prevent killing them. I just wanted to create a scene from one of my favorite animes in my past life and remove it from my bucket list.'

Izuna turns towards Naruto and notices his sparkling eyes which almost blind him.

'Ugh… fine! Naruto meets the minimum requirement to replicate this feat. He has enough chakra reserves and he will soon master Senjutsu. Although he doesn't have the power release cloak, he can make up for it by using the Nine-tails chakra cloak. The only thing he is lacking is a durable body at the moment. But with enough training, he can achieve it eventually. Hmm… perhaps after we return to the village, I will drop him in Might Guy's boot camp. He will beat Naruto in shape.

Also, Naruto has a versatile Ninjutsu ability in Rasengan and I also taught him a lot of other ninjutsu to expand his arsenal. However, he is lacking in Taijutsu and close combat. Perhaps this technique might make him the one-punch man of the shinobi world.'

"Alright, Naruto! I will teach this technique to you. But it's very difficult and has a very high requirement."

Izuna teaches the necessary steps to Naruto.

"First of all, you have to perfect your chakra control. It will be a challenge with your massive chakra pool, but I think you learn it, eventually. Second is Senjutsu…"

Izuna rambles for another hour and Naruto listens with complete interest.

"Alright, I will give a little demonstration of this technique! So, please get away a little."

"Yes, Nii-san!"

Naruto flickers a hundred meters away from Izuna.

"Good! Now watch closely!"

Izuna infuses his chakra and nature energy into his fist and stretches it backward. He also layers the power release chakra on top of it. The chakra on Izuna's fist turns golden as a result. Yellow lightning bolts jolt around his fist.

HAAA…

Izuna aims his fist toward a mountain in distance and punches out.

BANG…

A massive crater forms beneath Izuna's feet and the powerful shockwaves blow away the forest in his line of sight. Back in the distance, a huge fist print appears on the mountain.

Rumble… rumble…

The top of the mountain crumbles apart to create a landslide. Various animals and birds hurriedly escape from the area.

"Oops! I overdid it."

Izuna whistles and turns around.

"So, did you see that?"

"Yes!" Naruto frantically nods his head.

Sigh…

'What hardships I have to face just to mimic a fraction of One-punch-man's true strength!'

"Ah! I almost forgot. Naruto, follow this training regimen. One hundred pushups! One hundred sit-ups! One hundred squats! And a ten-kilometer run…"

"Umm… Nii-san, that's too easy!"

"I am not done yet. Perform this training set a hundred times. Do you understand Naruto?" Izuna turns to Naruto.

"Yes, nii-san, I will start right now." Naruto dashes off in the distance.

"Good! But don't overdo it."

"Oh! I forgot to tell him the turning off the AC but with Tsunade, it won't be a problem."

Izuna whistles and surveys the isolated island full of dangerous beasts.

*********End of Flashback*********

Onoki and A also pay attention to Naruto.

"So, that's the power of the jinchuruki of the nine-tails. The power he used in his battle against the legendary Rinnegan wielder Pain of Akatsuki." Onoki remarks.

"This brat…" A also stares at the smoking fist of Naruto.

'Can I withstand such a punch with my lightning cloak?' A question himself.

'I probably can't!' His inner voice answers him. Naruto's figure overlaps with the figure of Izuna in A's mind.

"This brat… he reminds me of Izuna Uchiha!" A murmur as he recalls his bet with Izuna a few years ago. (Chapter 123)

At that time, he had bet with Izuna to save the life of his comrade. Both of them agreed upon a test of endurance. Izuna's punch sent him into a coma for three days. The feeling of pure strength is still etched on his body.

A stare at the fist mark on his abdomen.
