This Naruto is too easily persuaded.

"Everyone, gather!"

With a whistle from Iruka, the students who were still playing around reluctantly came to the playground to assemble.

Iruka glanced around to make sure no one was missing, then held up the roster and said:

"Today's physical education class was simple: run 50 laps around the track."

"Anyone who can't finish the run within the allotted time today will have to stay for extra training this weekend!"

Iruka looked at everyone expressionlessly.

"Huh?! 50 laps?"

“Please spare me…”

"Ugh, I hate long-distance running!"

A sigh of lamentation suddenly arose from the crowd.

Kiba Inuzuka gave this a disdainful smile.

"That's it? Even Akamaru could easily cover that distance, right Akamaru?"

"Woof!"

Choji Akimichi looked worried. "Shikamaru, what should we do...?"

Nara Shikamaru, meanwhile, was yawning listlessly.

"Ugh, this is such a hassle, I just want to finish this run and go to sleep."

Uchiha Sasuke had a cold expression, his hands in his pockets.

If you can't even complete this level of warm-up, when will you ever be able to get revenge on that man?

A group of girls screamed, "Sasuke is so cool!"

Naruto pushed up his glasses and adjusted his posture.

In the past, this level of long-distance running might have given him a slight headache.

but now……

Naruto first took a deep breath, then began to regulate his breathing, his chest rising and falling slightly in a specific rhythm.

"Perfect timing to test the results of this week's training."

[Breathing Technique Proficiency (65/1000)]

Although it still doesn't reach the level of a complete series.

But he recently discovered that his aerobic exercise ability has made amazing progress.

"You need to keep a low profile...don't stand out too much, just keep your skill level above average."

Naruto suppressed his eagerness and kept reminding himself to keep a low profile.

"Ready—Go!"

At a command, more than thirty students rushed out in a chaotic frenzy, like ducks released from their enclosure.

For the first few laps, everyone was able to barely maintain formation.

Kiba Inuzuka, along with Akamaru Oki, were in the first group, wanting to compete with Sasuke.

"Hehehe, Sasuke, I'm in great shape today, I definitely won't lose to you!"

Kiba Inuzuka turned around defiantly and said.

Sasuke snorted coldly, suddenly accelerated, and instantly widened the distance between them, responding to Kiba's provocation with his back.

As the number of laps increased, the queue grew longer and longer.

Those with poor physical fitness have already started to fall behind, and Nara Shikamaru has begun another phase of resignation.

The playground was filled with heavy breathing and footsteps.

Naruto mingled in the middle of the group, unhurried and unhurried.

Thanks to the effect of Aizen's glasses, few people have noticed him lately—except for Hinata, who is always watching him.

He was like a ghost, and without anyone noticing, he even showed some of the same tendency to become invisible as Shino Aburame.

His pace matched his breathing.

That special breathing rhythm allows a large amount of oxygen to be continuously converted into kinetic energy.

Even after running 20 laps, he was still not red in the face or out of breath.

Even the new dark blue shirt he was wearing wasn't soaked with sweat.

It felt as relaxed as taking a leisurely stroll in a park.

By the thirtieth lap, Kiba Inuzuka was already panting heavily.

He had just been arguing with Sasuke Uchiha and accidentally lost his rhythm, and now he was feeling tired.

But he remained calm.

Because in the class, at least in terms of physical fitness, only Uchiha Sasuke could consistently outperform him.

Just then, I heard rhythmic footsteps and breathing behind me.

Kiba Inuzuka instinctively turned around, "Huff... huff... Naruto?"

He looked at the bespectacled man in front of him with some disbelief.

"Huff... What's that strange noise? It sounds like... a bellows... Huff, are you exhausted?"

Because of his breathing technique, Naruto's breathing is indeed louder than that of an ordinary person.

Naruto turned his head to the side, and through his blue glasses, he glanced at Kiba Inuzuka.

There was no reply, only a slight upturn of the corners of his mouth, revealing a polite smile.

Maintaining the same rhythm, but with a slight push of his feet, he easily passed Kiba Inuzuka.

Only Kiba Inuzuka was left standing there, gathering dust.

"...Huh? When did that guy start running so fast?"

The sun gradually set.

Forty-five laps.

At the very front of the group, Sasuke's forehead was covered in fine beads of sweat.

This distance is also a considerable challenge for him, especially since he has to maintain a leading pace.

"Hmph, those people behind have been left far behind, haven't they?"

Sasuke thought to himself.

As a member of the Uchiha clan, one must always be number one in any test.

This was his pride, and also his capital to take revenge on that man.

With little distance left, he subconsciously slowed down, trying to catch his breath.

Just then, a strange sound entered his ears.

hiss - huh -

Sasuke frowned and turned around to look.

Less than two meters behind him, a dark blue figure was slowly chasing after him.

It's Naruto Uzumaki.

What surprised Sasuke the most was not that Naruto was able to catch up.

Instead, after catching up, his expression didn't change much.

Forget about looking disheveled, Sasuke even felt that this guy probably hadn't shed a single drop of sweat.

"What's wrong with this guy?!"

Sasuke's pride made it impossible for him to accept the fact that he had been overtaken by the bottom runner.

"Trying to overtake? Dream on!"

So he gritted his teeth and forced himself to accelerate, trying to shake off Naruto behind him.

Unfortunately, no matter how fast he sped up, the sound of breathing behind him followed him like a shadow and into his ears.

He's fast, and Naruto is fast too.

He's slow, and Naruto is slow too.

Naruto kept a distance of half a meter from him at all times, neither overtaking nor falling behind.

That invisible sense of oppression gradually caused Sasuke's mind to become unbalanced, and his originally regular breathing gradually became disordered.

"Damn it... damn it!"

Sasuke gritted his teeth, his lungs began to burn, and his legs felt like they were filled with lead.

The voices behind him remained calm.

Finally, the finish line is in sight.

Sasuke mustered his last bit of strength and staggered across the white line.

Almost at the same time, the figure next to me also crossed the finish line.

"Hoo... Hah..."

Sasuke braced himself on his knees, panting heavily, sweat dripping from his chin onto the ground.

Naruto, who was next to him, slowly stopped and gently pushed up his glasses.

"call."

He let out a long breath, the airflow even creating a considerable gust of wind.

Then he took out a handkerchief and wiped the sweat from his head.

"He got a little carried away."

Naruto muttered to himself, glancing at the system.

[Breathing Technique Proficiency (85/1000)]

Unexpectedly, just one run increased my breathing technique proficiency by twenty points.

Previously, he could only increase his proficiency by a maximum of ten points a day.

Naruto then discovered that practicing breathing techniques during aerobic exercise could improve proficiency much faster.

Sasuke suddenly raised his head and stared intently at the former loser beside him.

"Not just his appearance... even his physical abilities..."

"What's wrong with this guy?"

Not only Sasuke, but even Iruka was taken aback.

Not to mention the other students who were exhausted and collapsed on the ground.

but……

I can feel the abundant energy still within me.

Looking at Iruka-sensei's incredulous gaze and Sasuke's fixed stare at him.

An unprecedented sense of satisfaction quietly welled up in Naruto's heart.

He subconsciously pushed up his glasses to hide the barely suppressed smile on his lips.

"It feels so good to be valued by others through hard work."
