Naruto: Uchiha Survivor Forced to Save the Shinobi World-Chapter 356: Revealed Deficiencies

Because the dojutsu power of this newly fused Eternal Mangekyō Sharingan was so strong, Shinji's chakra gain when driving it through Susanoo Tomoshibi was immense.

Yet the greater the gain—

The more it highlighted an uncomfortable truth:

Shinji's own Eternal Mangekyō Sharingan wasn't perfect.

There was still room for improvement — a gap that could be complemented by another Sharingan.

"So much for thinking my eyes had already reached the pinnacle of the Sharingan..."

Shinji lightly shook his head.

Now it was clear—

The reason why driving regular three-tomoe Sharingan and ordinary Mangekyō Sharingan had yielded only modest benefits before was not because Shinji was perfect, but because the gap between their tiers was simply too large.

Their chakra nature couldn't complement his own.

But—

When driving a same-tier Eternal Mangekyō Sharingan, even though the chakra synergy was naturally less efficient than between entirely different systems, the overall gain was still far superior to that from regular Sharingan or Mangekyō Sharingan.

After closing his eyes and carefully sensing again, Shinji sighed inwardly:

"I didn't expect Karin's Eternal Mangekyō Sharingan to have this much power."

But on second thought, it made sense.

After all, the two Mangekyō Sharingan used to create Karin's Eternal form had been perfectly restored using her own high-quality special Yang Release chakra.

In a way—

Those two Mangekyō Sharingan were in a "newborn" state —

The peak of vitality, the freshest and strongest they could ever be.

Fusion under these circumstances naturally produced an exceptionally potent Eternal Mangekyō Sharingan.

Shinji made a rough evaluation.

Karin's current Eternal Mangekyō Sharingan likely already possessed 70% to 80% of the dojutsu strength of his own eyes.

An astonishing achievement.

However—

Now that he clearly realized that neither his own nor Karin's Eternal Mangekyō Sharingan had reached the true pinnacle, Shinji fell deep into thought.

After all—

The Rinnegan was the gate to the Six Paths tier.

To evolve into the Rinnegan, the dojutsu strength of the Eternal Mangekyō Sharingan needed to be as high as possible.

Perhaps—

Only an Eternal Mangekyō Sharingan that had reached the ultimate extreme could truly have a chance to evolve into the Rinnegan!

But as things stood—

Neither his own eyes,

Nor Karin's eyes,

Had yet reached that summit.

"Is there any way... to further enhance the dojutsu strength of the Eternal Mangekyō Sharingan?"

This question instantly took root in Shinji's mind.

In truth—

Once reaching a certain level of strength, conventional methods were useless for further increasing chakra or dojutsu power.

After pondering for a long while, Shinji could only come up with two and a half possible methods:

Slow natural accumulation over time.

Like how Uchiha Madara, after surviving his battle with the First Hokage and sacrificing one eye to Izanagi, had to endure until the twilight of his life before barely awakening the Rinnegan.

Shinji and Karin were still young—

Far from the physical peak of their bodies.

Given enough time—ten or twenty years—their dojutsu strength would certainly grow stronger. ƒreeωebnovel.ƈom

Through the power of Yin-Yang unity — the force known as All Creation Power — to nourish the Eternal Mangekyō Sharingan.

Shinji's own Eternal Mangekyō Sharingan was so strong because he had, through various methods, acquired and absorbed fragments of All Creation Power to nourish his eyes.

The final "half a method" is to extract chakra from the reincarnation of Ōtsutsuki Indra to enhance dojutsu strength.

The first method was far too slow.

Shinji couldn't afford to wait decades.

Thus, realistically, only the second method and the "half method" were feasible.

At the thought of All Creation Power, Shinji frowned slightly.

Karin's body hadn't fused any new Shinra Myriad Phenomena for quite a while now.

But this was to be expected.

The ability to produce Shinra Myriad Phenomena was a power belonging to the Rinnegan tier.

Even someone like Nagato, who had a transplanted Rinnegan, struggled in this regard.Let alone Karin, who had only recently fused her Eternal Mangekyō Sharingan.

Previously, the brief traces of Shinra Myriad Phenomena in Yakumo and Karin's bodies had only formed during the initial collision of extremely high-quality Yin and Yang chakra—

A fleeting, unsustainable phenomenon.

"Looks like Karin's First Hokage Cell transplant surgery must be expedited."

After gaining her Eternal Mangekyō Sharingan, the Yin-Yang balance within Karin's body had shifted drastically.

The Yin Release chakra within her Eternal Mangekyō Sharingan now far surpassed the Yang Release chakra of her original body.

Yin dominant, Yang weakened.

Thus—

Only by implanting First Hokage cells to strengthen her Yang Release chakra could balance be restored.

Only then could she achieve the union of Yin and Yang once again, creating new Shinra Myriad Phenomena.

Moreover—

Unlike the heavily diluted White Zetsu cells, the Hidden Leaf's preserved stock of First Hokage cells contained a much higher proportion of Ōtsutsuki Asura's chakra.

Thus, transplanting First Hokage cells into Karin would also infuse her with a portion of Asura's power—Strengthening her Yang Release to a whole new level.

After completing various tests—

Shinji carefully removed Karin's Eternal Mangekyō Sharingan and placed them back into the nutrient tank.

His emotions were complicated.

Rather than testing Karin's new eyes—

It felt more like he had been testing his own Eternal Mangekyō Sharingan.

Because Karin's eyes—

Were simply too powerful!

So powerful that they finally exposed the hidden flaws in his own Eternal Mangekyō Sharingan — flaws that had previously gone unnoticed.

"Next, I'll need to test Karin's own control over her Eternal Mangekyō Sharingan."

With that thought, Shinji withdrew his Susanoo and disappeared into the shadows.

Meanwhile—

With the Hidden Sand volunteer dead, the overt confrontations between villages had shifted into secret maneuvering.

The heavy atmosphere suffocating the village lifted somewhat.

Yakumo, in particular, appeared much more relaxed, occasionally showing radiant smiles at the Academy.

Taking the initiative, Shion proposed gathering a few familiar classmates for a barbecue outing.

Naturally—

This made everyone remember the still-recovering Karin.

"Weird," Shion muttered. "It's been so long. How come Karin still hasn't healed?"

Yakumo hesitated, then said:

"Let's go visit her. Come to think of it, I've never actually visited Karin since her injury. Besides, I've learned a lot of new medical ninjutsu from Lady Tsunade recently. Maybe I can help her."

Sakura immediately nodded:

"Let's go after school!"

When school ended—

Shion, Yakumo, and Sakura gathered together, preparing to visit Karin.

Ino, Hinata, and Tenten, hearing the news, decided to join in as well.

They bought some fruits and sweets—

Then knocked on the door of Karin's apartment.
