Rising Shadows: Uchiha's Wrath

[Ordinary Uchiha practitioners can begin practising this technique at age five.]

[One year of practice open one Tomoe Sharingun; three years open two Tomoe; another three years open three Tomoe; another six years unlock the Sharingun; and after twelve years, the Eternal Sharingun.]

[Those with strong Uchiha bloodline and high talent will progress faster.]

[Until reaching the Eternal Sharingun, practitioners can only attain abilities one level below the host.]

...

After reading the scroll and the system's introduction, Kaito took a deep breath. This cultivation method was incredibly powerful!

According to the system, after mastering this method, Uchiha individuals could unlock the first Tomoe at age six, the second at nine, the third at twelve, the Sharingun at eighteen, and the Eternal Sharingun at thirty!

And this was for clans with ordinary talent; those with stronger talent would progress even faster!

It was tailor-made for the current Uchiha clan!

After leaving and destroying Konoha, Kaito would not be content with the status quo. He had ambitions of his own now!

That is, to lead his people in unifying the ninja world!

To achieve this, Kaito would have to face the entire ninja world, but with strength, he could sweep away all opposition!

And the people who placed their faith in him would be his allies, the most trustworthy individuals to govern the ninja world in his absence!

However, currently, these clan members are too weak. There were only four years until the plot began and eight years until the chaos in the ninja world.

In such a short time frame, their strength couldn't improve significantly, and they couldn't offer much assistance.

But that would change now. With this secret method, their strength would increase dramatically!

Especially Uchiha Tekka and Uchiha Izumi, with their talents, they might unlock the Eternal Sharingun in eight years with dedication to their cultivation!

At that point, they could shoulder more responsibilities, easing the burden on Kaito!

"It seems the system is also encouraging me to unify the ninja world!"

Kaito smiled faintly, carefully storing the scroll.

"Now, onto the main event!"

A gleam of determination flashed in Kaito's eyes as he opened his ninja kit and retrieved the three-point seal scroll.

He unfurled the first scroll, laid it flat, and formed a seal.

Placing his hand over the centre of the scroll, he commanded,

"Activate!"

Instantly, four vials materialized under Kaito's palm!

---

Inside these four bottles are naturally the two pairs of Sharingan eyes of Fugaku and Shisui captured by Kaito!

"System, can you help me directly integrate the ocular power of these two pairs of Sharingan into my Sharingan?"

Because he has no kinship with Fugaku and Shisui, Kaito can't guarantee that he can obtain their ocular power by transplanting their eyes.

Moreover, if he had to change his eyes, Kaito would rather refrain. After all, he didn't want to give up his original organs to transplant other people's organs into himself!

Besides, he still has a system. As long as he continues to use the Sharingan more, it will naturally advance to the Eternal Sharingan!

At most, he would lose one ability, and it is estimated that it will not have much effect in the future. It is not worthwhile for Kaito to change his eyes!

[Can! ]

The system's answer is still so simple and clear, but Kaito is very happy after hearing it!

"Great!"

A smile appeared on Kaito's face, and then he immediately opened the bottle and took out Fugaku's Sharingan first.

"System, start absorbing it!"

As soon as the words fell, Fugaku's Sharingan in Kaito's hand changed.

I saw that from Fugaku's Sharingan, grey thin lines began to emerge, and two grey fog masses condensed above the Sharingan.

At the same time, Fugaku's Sharingan began to gradually lose its lustre.

Obviously, these grey lines are the ocular power of Fugaku's Sharingan!

When the last ocular power was drawn out, Fugaku's Sharingan instantly turned into fly ash and dissipated from Kaito's palm!

Then, those two ocular powers flew towards Kaito's eyes!

Kaito was not prepared to block, so the two ocular powers quickly merged into Kaito's Sharingan.

The next moment, Kaito felt a coolness in his eyes, and then the ocular power of his own Sharingan began to increase rapidly!

At the same time, Kaito could feel that he had two more abilities - those two ocular abilities of Fugaku!

There is a system shot, so the swallowing of pupil power is very smooth and fast.

After a while, Kaito opened his eyes again, but he frowned.

"I didn't expect that after absorbing Fugaku's Sharingan, I still haven't reached the bottleneck of the Sharingan."

"It seems that my pair of Sharingan eyes has great potential! I still need to absorb the ocular power of two Sharingan eyes to advance!"

Thinking of this, Kaito did not hesitate and immediately took out Shisui's Sharingan.

After absorbing Shisui's ocular power and obtaining Shisui's two pupils, Kaito's Sharingan finally reached the bottleneck!

***

[Detected that the host's Sharingan has reached a bottleneck, Does the host want breakthrough? ]

"Breakthrough!"

[The Sharingan successfully broke the bottleneck, congratulations to the host for obtaining the Eternal Sharingan! ]

As soon as the system's voice fell, Kaito felt that the eyes that had absorbed the two pairs of Sharingan and their ocular power had already reached their limit.

At this moment, the ocular power in them had increased again, and it had been enhanced several times in a moment!

However, because it is not a Sharingan obtained by transplantation, the pattern of Kaito's Sharingan has not changed.

When the ocular power of both eyes stabilized, the chakra in Kaito's body also began to rise sharply, and soon reached the level of the late film level!
