Naruto: Uchiha Survivor Forced to Save the Shinobi World-Chapter 373: Seal

Shinji gave an awkward smile after hearing her words.

The seal he had hastily devised was clearly useless against Karin, who had now successfully fused with the First's cells.

Based purely on theoretical data.

Having undergone the transplant of the First's cells and achieved the highest level of fusion between the Uzumaki and Senju Sage Bodies, Karin's Sage Body might not yet rival the First's at his prime, but excluding the Ōtsutsuki, it was undoubtedly the strongest in the current shinobi world.

Furthermore.

Nourished by the 'All Creation Power' earlier, the dojutsu power of the Eternal Mangekyō Sharingan in her eyes had undergone a qualitative leap.

If, before this, Shinji's Eternal Mangekyō Sharingan could be considered the strongest pair of Sharingan in the shinobi world, it was now uncertain who held that title.

Shinji even had a faint feeling that, at this moment, his Eternal Mangekyō Sharingan might still have a slight edge. But as time passed, the title of 'strongest Sharingan' would inevitably change hands.

Because, after achieving Yin-Yang fusion, Karin's body was constantly producing minute amounts of 'All Creation Power.' Under the continuous nourishment of this 'All Creation Power,' both her constitution and dojutsu power would keep strengthening.

So, even if Shinji's Sharingan was slightly superior at this moment, that advantage would gradually fade with time.

This period might be half a month, a week, or even just a few days.

Thinking of this, Shinji couldn't help but compare the current Karin to the First and Uchiha Madara before the Battle of the Valley of the End.

Then, he shook his head inwardly.

Although Karin's theoretical data was already astonishing, compared to the First and Uchiha Madara at the Valley of the End, she still fell short.

In terms of constitution, even if Karin was close to the First, the First also mastered a wide array of 'Wood Release' secret techniques and sage arts.

The sage arts alone created a vast gap.

With the enhancement of sage chakra, 'Wood Release' could sweep through a complete Nine-Tails combined with a fully manifested Susanoo.

As for Uchiha Madara, as the reincarnation of Ōtsutsuki Indra, the dojutsu power of his Eternal Mangekyō Sharingan back then undoubtedly surpassed Karin's current pair.

Add to that the numerous secret and forbidden techniques Madara had mastered, and his overall strength was also far above Karin's current level.

This didn't even account for the combat experience and battle instincts of the First and Madara.

After all, theoretical data was just that—data. Skill was something else entirely.

If factors like experience, talent, and awareness—things difficult to quantify—were considered, Karin's gap would be even larger. If she faced the First or Madara from the Valley of the End, they might see through her weaknesses in a single glance, target her vulnerabilities, and take her down in just a few moves.

Seeing Shinji lost in thought, Karin softly called out, "Leader, are you okay?"

"I'm fine." Snapping back, Shinji smiled and thought to himself, What am I thinking? She's only eight or nine years old!

At this age, her body hadn't even reached its peak development. It was easy to imagine how vast Karin's growth potential was.

Even if she couldn't compare to the First or Madara from the Valley of the End now, in the foreseeable future, Karin would surely surpass them.

Feeling her overwhelmingly exaggerated chakra, Karin said with concern, "Leader, if I go to the shinobi academy like this, won't people notice?"

Shinji replied, "That's inevitable!"

At this moment, Karin was like a blazing torch in the dark. Even non-sensory shinobi could detect the tidal surges of chakra emanating from her.

Let alone ordinary people—even Shinji felt considerable pressure.

Karin looked troubled. "Leader, what should I do?"

Shinji thought for a moment and said, "You're currently in the post-surgery fusion phase, and your body's condition is still unstable, so it's normal to occasionally feel your chakra spiraling out of control and leaking outward. This will gradually stabilize over time."

"Oh!"

Karin let out a sigh of relief.

Shinji continued, "As for concealing your chakra, my sealing techniques probably won't work on you anymore. From now on, you'll have to rely on yourself."

In the field of sealing techniques, he was still a beginner and lacked the confidence to seal the current Karin.

Karin pointed at herself in disbelief. "Rely on myself?"

"Yes!"

Shinji nodded.

In the shinobi world, the applications of sealing techniques were limited only by imagination, not possibility.

For example, jinchūriki sealed powerful tailed beasts within their bodies. Or the bell artifact carried by Shion, which the previous priestess used to seal Shion's priestess powers.

Even sage arts had been incorporated into sealing techniques by Orochimaru, who created the 'Cursed Seal,' a low-grade version of Sage Mode.

After some thought, Shinji confirmed, "You've already learned the 'Four Symbols Seal' I taught you, right?"

"I've learned it," Karin said quietly, sounding a bit uncertain, as if she had only recently mastered it.

"You can inscribe the sealing formula of the 'Four Symbols Seal' onto a small, portable object, and then..."

Shinji carefully explained the sealing concept to Karin.

Clearly.

His idea was inspired by the bell artifact Shion carried.

However, since he didn't know how to craft artifacts, he could only guide Karin to create a simple, temporary artifact by inscribing the sealing formula.

Though simple, because it was Karin's own chakra sealing herself, there was no risk of her chakra being too powerful and easily breaking free from the seal's restraints.

The reason he had Karin do it herself was that, while both were novices in the 'Four Symbols Seal,' Karin's current chakra level surpassed his. Moreover, as a true Uzumaki, she had an innate advantage in using the Uzumaki clan's sealing techniques.

After listening to Shinji's guidance, Karin immediately began her attempt.

She first took off her coat, then formed hand signs to activate the 'Four Symbols Seal.' Following Shinji's instructions meticulously, she inscribed the sealing formula onto the inner lining of her coat.

In an instant.

The sealing formula, like flowing ink, spread across the inner lining of Karin's coat, then quickly took shape and gradually faded from view.

Karin hurriedly put the coat back on.

As the seal took effect, the prickling sensation Shinji had felt ever since Karin's surgery succeeded finally vanished.
