I will use the ninja world to aid my cultivation of immortality.

Uchiha Shisui displayed an astonishing Body Flicker Technique, instantly appearing behind Naraku.

The red sword was drawn.

The crimson blade, wreathed in terrifying flames, was swiftly slashed towards Naraku by Uchiha Shisui.

Gravity barrier isolation.

The fiery slash was blocked again.

Uchiha Shisui's eyes sharpened, and he skillfully used the "Phantom Body Flicker Technique".

Dozens of illusory clones, indistinguishable from the real ones, constantly shuttled back and forth around Naraku.

Flaming slashes came from all directions towards Naraku.

However, due to the all-around gravity barrier, no matter how Uchiha Shisui attacked, he could not inflict any damage on Naraku.

Even as Uchiha Shisui attacked, Naraku, with his arms crossed, was still observing his opponent with great interest.

He naturally already knew that Uchiha Shisui had evolved the Mangekyou Sharingan.

To be precise, it was Uchiha Shisui who took the initiative to report to him using his ninja hawk at the first opportunity.

The evolution of the Mangekyou Sharingan requires not only the innate talent but also sufficient emotional stimulation.

The same applies to the evolution of Uchiha Shisui.

He evolved from the shock of witnessing his subordinates being killed during a battle between Liangshanbo and Xinmuye.

Although this process was brutal, it must be acknowledged that after Uchiha Shisui's Sharingan evolved into the Mangekyou Sharingan, his strength experienced a leap forward.

This is one of the reasons why Liangshanbo and Xinmuye clashed for more than a year, yet only a handful of people died.

Because Uchiha Shisui withstood the pressure from Tsunade and Minato Namikaze, the two greatest dangers.

Let's talk about the Mangekyou Sharingan.

The Sharingan is the eye that reflects the soul.

Unlike the Sharingan that Naraku forged into magical artifacts.

Uchiha Shisui's evolution followed a normal path.

Due to his different circumstances, the eye technique he developed in his Mangekyou Sharingan was not "Kotoamatsukami," but rather a technique called "Omota-ryu."

That's right.

Although the eye techniques are different, the eye techniques nurtured by Uchiha Shisui's Mangekyou Sharingan are still the same as those of "Kotoamatsukami," which are two eye techniques in one.

The deaths of his subordinates fueled Uchiha Shisui's desire for greater power, which is why his eye technique, "Omota-ryu," was designed to enhance strength.

The power of ninjutsu, taijutsu, genjutsu, and so on can all be enhanced by the "Omota-ryu".

At this moment, the battle between Uchiha Shisui and Naraku was a good demonstration of the power of the "Omota-ryu" eye technique.

From the initial Fire Dragon Technique, to the Instantaneous Movement Technique, Sword Leap Flame, and Phantom Instantaneous Movement Technique.

The power it displayed far exceeded Uchiha Shisui's normal level.

All of this was caused by the enhancement of the eye technique "Omota-ryu".

Don't be fooled by the fact that Uchiha Shisui's attacks couldn't harm Naraku at all.

This was entirely because his opponent at that time was Naraku.

If it were someone else.

For example, Uchiha Mikoto, who also possesses the Kaleidoscope Sharingan.

Mikoto Uchiha might not actually be able to defeat Shisui Uchiha.

Genius is synonymous with breaking the rules.

Although Uchiha Shisui was young.

However, the dual-wielding eye technique is itself proof of talent.

Whether it's "Kotoamatsukami" or "Kamui", it doesn't matter.

Including Naraku's "Large Property".

The dual-element eye technique may seem to have one less element than a normal kaleidoscope eye technique, but in reality, it is a qualitative change achieved through quantity.

Strengthened by the "Yumuduo Stream".

This allowed Uchiha Shisui to unleash B-rank ninjutsu with power approaching that of S-rank ninjutsu.

Especially in his specialty, the Instantaneous Movement Technique.

Its speed is so fast that it is in no way inferior to time-space teleportation techniques like the Flying Thunder God Technique in battle.

That is, Naraku.

If it were someone else, with less insight, even if their basic strength was comparable to Uchiha Shisui, they would be suppressed and have little ability to fight back.

The dazzling offensive lasted for a moment.

Unable to break through the gravity barrier by any means, Uchiha Shisui, who was breathing heavily, stopped.

"Your Majesty, your defense is too strong; I simply cannot break through it." Uchiha Shisui said with a look of shame as he sheathed his red sword.

When His Majesty summoned him to test his abilities, he originally intended to perform well.

Defeating His Majesty was naturally impossible, but being unable to even touch Him, as he was doing now, undoubtedly made him feel ashamed.

Chapter 278 Three

"Shisui, there aren't many people in the entire ninja world who can hurt me. Based on your performance just now, it was actually quite good." Naraku couldn't help but laugh when he saw the other's ashamed look.

Uchiha Shisui considered the battle record of His Majesty that he knew.

It seems that in his memory, His Majesty had never been injured in battle.

Thinking about it this way, he immediately felt much better.

"Your Majesty is right. I overestimated myself." Uchiha Shisui scratched his head sheepishly.

Naraku laughed and said, "It's not an overestimation; you just don't know my strength."

As he spoke, his gaze fell upon the other person's Mangekyou Sharingan, and he continued, "And don't forget about eye care. You've been using your eye techniques the whole time, which has taken a toll. You should use the Heavenly Divine Water to nourish your eyes properly."

"It's your Majesty!"

Uchiha Shisui obediently summoned a water bottle using the contract on the back of his hand, and then carefully poured out the Heavenly Water and dripped it into his eyes.

The nourishing effects of the Heavenly Divine Water can also be applied to the Mangekyou Sharingan.

Although it cannot promote the evolution of the Sharingan compared to the nurturing of true qi.

However, if it's just a matter of damage, the Heavenly One Divine Water at the minor completion stage is enough to repair the damage to the Mangekyou Sharingan, just like Hashirama Senju's cells.

This is why Shisui Uchiha's Mangekyou Sharingan remained in good condition despite his numerous battles with Tsunade and Minato Namikaze.

Upon learning that Uchiha Shisui had evolved the Mangekyou Sharingan, Naraku informed him about the benefits of Tenichi Shinsui for the Mangekyou Sharingan.

With a drop of the Heavenly Divine Water, Uchiha Shisui's Mangekyou Sharingan was quickly nourished.

The eyes, which had previously suffered a decline in strength, were quickly relieved.

Naraku chatted with the other party for a while longer before waving him away.

After Uchiha Shisui left.

Naraku, who remained at the training ground, began to ponder.

Over the past year, Uchiha Shisui has indeed made tremendous progress.

Aside from the Sharingan evolving into the Mangekyou Sharingan, he has made great progress in other aspects as well.

Even without considering the magical treasures he bestowed upon him, his actual strength was already firmly at the level of Elite 2.

Moreover, it is nourished by resources such as Tiger Wolf Pill and Heavenly Divine Water.

Uchiha Shisui, who awakened the Mangekyou Sharingan earlier than Itachi Uchiha in the original story, had chakra and a body that could support the Mangekyou Sharingan well.

As he pondered, Naraku raised his right hand, and three [Eternal Mangekyou Sharingan] immediately appeared in his palm.

That's right, it's three [Eternal Mangekyou Sharingan].

Of these three Eternal Mangekyou Sharingan, one was original, while the other two were recently crafted.

A total of fourteen Sharingan were seized at the time.

Five are three-tomoe gems, and the rest are two-tomoe gems.

Of the five three-tomoe gems, he bestowed three upon Nono, Natsuhisa, and Ame.

The remaining two three-tomoe Sharingan were nurtured by him into Mangekyou Sharingan, and finally fused with the Mangekyou Sharingan of Uchiha Kagami and Uchiha Madara to create the first [Eternal Mangekyou Sharingan].

Until now.

The remaining nine two-tomoe Sharingan were also nurtured to the Mangekyou Sharingan level, and then four of them were fused together to successfully create two more Eternal Mangekyou Sharingan.

"For the Eternal Mangekyou Sharingan to evolve into the Rinnegan, the cultivation of Light True Qi is no longer sufficient. Fortunately, I have an understanding of the storyline, and now, after my re-refinement and the incorporation of Hashirama Senju's cells, there is hope for its further evolution."

Naraku smiled slightly as he used his divine sense to see inside the three Eternal Mangekyou Sharingan.
