Naruto: My Progress in Konoha.

Uchiha Haruki calmed his mind and wiped the blood from beneath his left eye. Then, steadying himself again, he turned his focus inward—this time to the power sealed within his right eye.

Seconds ticked by.

Moments later, Haruki slowly opened his eyes. A faint ripple of chakra spread out, but his body showed no visible change.

Still, Haruki knew—the ocular power in his right eye had activated.

Like the ability in his left eye, the Mangekyō Sharingan's right eye ability was non-offensive.

Its name: Hito-no-Mikoto—The Sovereign of Self.

And its effect was singular:

Complete control over one's own body.

This meant everything that constituted the concept of "self"—organs, tissues, cells, consciousness—could all be influenced and regulated through this power.

Of course, given Haruki's current skill level, he couldn't yet manipulate these aspects with pinpoint precision.

For now, his influence was limited to basic organ-level control.

He could, for instance, regulate his heartbeat, adjust the digestion rate of his stomach, or manage the secretion of adrenaline.

At first glance, compared to the invincible Amatsu-no-Mikoto, this new ability, Hito-no-Mikoto, seemed like the weakest ocular power ever.

But this was just the beginning.

Yes, its current use was limited—but its growth potential was immeasurable.

Right now, its precision was low, and its versatility was limited. But as Haruki's skill and chakra control advanced, the precision would improve—and so would its potential applications.

He could eventually:

Control muscles to exert 100% of their potential.

Remove the natural limiters the body places on chakra usage.

Force the body to rapidly adapt to extreme environments.

This last application—adaptation—was essentially a form of controlled evolution.

Previously, Haruki had been worried about whether he could evolve his Mangekyō into the Eternal Mangekyō Sharingan, especially since he had no siblings to transplant eyes from.

But now, with Hito-no-Mikoto, those worries had vanished.

After all, the act of acquiring the Eternal Mangekyō Sharingan was essentially the correction of a genetic defect.

He didn't need a sibling's eyes—he now had a power that could manipulate and evolve his own body, especially when combined with his Yōshin no Jutsu, Reflection of the Heart Technique).

In other words, there was now no barrier on his path toward awakening the Eternal Mangekyō Sharingan.

Beyond that, body enhancement could also be fast-tracked with Hito-no-Mikoto.

Moreover, once this power reached a certain level, Haruki believed it could even repair the damage caused by the frequent use of the Mangekyō—perhaps even reversing blindness.

Yes, using Hito-no-Mikoto still placed strain on the Sharingan, but if he paced himself properly, the timeline for eventual blindness could be greatly extended.

With further bodily evolution and improved resistance, he wouldn't even need the cells of Hashirama Senju to prolong the lifespan of his Mangekyō.

This meant his peak battle strength could be sustained for a much longer period.

And as long as he reached the Eternal stage during that window—there would be no more risks to his Sharingan's longevity.

In that sense, Hito-no-Mikoto, while seemingly unassuming, would prove to be just as important as Amatsu-no-Mikoto, if not more so.

After spending some time sensing its effect, Haruki deactivated his Mangekyō Sharingan.

Then, he opened his Proficiency Panel.

A familiar soft blue light appeared before him:

[Perfected Skills]: —

Right away, he noticed his Spirit stat had jumped by 4 points after evolving his Sharingan from three-tomoe to Mangekyō.

Considering how high his base stats already were, that was an enormous leap.

Haruki estimated that his current spiritual power was at least 1.8 times what it had been before.

Given that his Physique stat was still lagging behind, he realized that his spiritual power was now nearly double his physical strength.

And that… was dangerous.

Crossing this ratio meant tipping into an imbalance—where chakra pressure could overwhelm the body, causing real harm.

In hindsight, Haruki was relieved that he hadn't rushed into awakening the Mangekyō earlier.

At that time, his Physique stat had only been 11—and with a Spirit stat now at 19, the 8-point gap would have been catastrophic.

Luckily, he had avoided that disaster.

Even so, enhancing his physical body had now become top priority.

Only by bringing body and mind back into balance could he prevent instability—and more importantly, unlock greater potential.

For example, despite gaining 4 points in Spirit, his chakra cap had only increased by around 50,000—from 71,000 to 120,000.

This wasn't ideal.

Likewise, his chakra regeneration rate had only risen by around 30,000 per day—going from 54,000 to 85,000 daily recovery.

Yes, that number was nearly double his current chakra reserve, but compared to the Spirit stat increase, it still felt underwhelming.

Fortunately, that untapped potential wasn't lost—just dormant. Haruki could still access it once he improved his physique.

Turning his gaze to the Bloodline section, Haruki confirmed what he had already sensed: his Sharingan had successfully evolved to the Mangekyō level.

However, seeing the new progress bar—(1/50000)—made him dizzy.

He quickly cast Yōshin no Jutsu, curious how much it would help advance his Mangekyō evolution.

Before, at Lv7, one cast of the technique would give +1 progress toward evolving his three-tomoe Sharingan.

Now… nothing.

One cast—no progress.

Another cast—still nothing. Though he could feel it was still working.

On the third attempt, the bar finally ticked forward by 1.

So now it took three casts to gain one point of progress.

And with the bar being five times longer than before… that meant the difficulty had increased fifteenfold.

Haruki almost collapsed from shock.

But soon, he calmed himself.

First of all, his chakra regeneration rate was much faster now—he had significantly more chakra to work with each day, so he wouldn't burn out too quickly.

Second, his proficiency with Yōshin no Jutsu was already approaching one-quarter of Lv7. It wouldn't be long before it hit Lv8, which would definitely increase its effectiveness on the Mangekyō.

And lastly—the most important point:

Now that he had awakened the Mangekyō Sharingan, he could begin planning to control a Tailed Beast.

Once he had a Tailed Beast acting as a chakra battery, then even a fifteenfold difficulty increase wouldn't be an issue.
