Rising Shadows: Uchiha's Wrath

"In the next few years, I will help you master my power as quickly as possible. When all this is over, we will have nothing to do with each other!"

Naruto took a deep look at Kurama, and then his consciousness returned to his body.

He opened his eyes, and Kaito was no longer around.

Naruto murmured,

"Have you left..."

He was silent for a moment, then fell asleep again. Tonight's experience had exhausted him, and he needed to rest well...

On the other side, Kaito had returned to the mountain where he and Uchiha and others had parted ways.

Looking at the ruins of Konoha below, Kaito murmured:

"Next time, it won't end so easily..."

After all, his figure disappeared in an instant.

***

In a cave, Kaito sat cross-legged.

He wasn't going to immediately join Uchiha Tekka and the others. After careful consideration, he decided to first absorb this newfound knowledge.

Kaito accessed the system panel and commanded: "Claim mission rewards!"

[Mission 3: Lead the tribe to resist and demonstrate the true power of Uchiha - completed!]

[Initiating task reward settlement...]

[Congratulations to the host for obtaining: Perfect Sage Mode; Mystery Scroll x1]

As the system finished speaking, a black scroll materialized in Kaito's hand.

Simultaneously, a flood of knowledge poured into Kaito's mind.

After absorbing this knowledge, Kaito's eyes lit up!

"Is this the cultivation method for the Perfect Sage Mode? Let's give it a try!"

With that, Kaito set the black scroll aside and began to perceive the free natural energy around him, following the method outlined in the message.

Due to the perfect cultivation method, coupled with the blessing of the Mangekyo, Kaito quickly sensed the natural energy and directed it into his body!

The Perfect Sage Mode provided by the system differed from the Sage Mode of the Three Holy Lands. The most challenging aspect was perceiving the natural energy!

Once this step was accomplished, the rest would follow naturally, with no inherent danger.

Soon, a golden aura appeared in Kaito's eyes!

"Is this the Sage Mode?"

Kaito opened his eyes, sensing the new, faint energy within his body, a smile forming on his face.

"Let's see how powerful it is!"

With that, Kaito's figure vanished instantly, reappearing outside the cave moments later!

Swiftly, he initiated seals, completing them in less than a second.

"Sage Style: Inferno Celestial Fireball Jutsu!"

In the next moment, Kaito launched a fireball with a nearly golden hue, over ten meters in diameter!

The fireball hurtled toward a nearby stone wall.

"Boom!"

With a thunderous crash, the twenty-meter-high stone wall vanished, leaving only molten magma and a crater more than ten meters wide!

Observing this, Kaito's pupils constricted, and he took a deep breath.

"Wow, the Sage Mode is truly formidable. The Sage Chakra Fireball isn't just several times larger than usual, its internal temperature is also significantly higher!"

However, Kaito quickly composed himself. After all, it was a product of the system, stronger than the SageMode of the Three Holy Lands.

Feeling the replenished Sage Chakra within him, Kaito thought to himself, "It seems that practising the Immortal Mode must become part of my daily routine from now on!"

"But luckily, I can use Shadow Clones, so it's not too burdensome."

The cultivation method in the Perfect Sage Mode provided by the system differed significantly from the original.

The Sage Chakra in Kaito's body was connected to the outside world. As long as his Sage Chakra was consumed, it would be quickly and automatically replenished from the outside!

However, the replenishment amount was limited to the original chakra capacity in his body. Therefore, his future goal would be to expand his chakra capacity from a glass of water to an ocean!

By then, maintaining the Sage Mode wouldn't be an issue!

And now, as long as Kaito retained the Sage Chakra within him, he could instantly activate the Sage Mode with a single thought!

"Not bad, truly a creation of the system!"

Satisfied, Kaito nodded, then exited the Sage Mode and returned to the cave.

"Now for this scroll!"

Kaito picked up the scroll he had set aside and quickly perused its contents.

Simultaneously, the system introduced it:

[Method of Sharingun Practice: The highest level can reach the Eternal Sharingun level.]

[After using this method, the practitioner will be 100% loyal to the host, and the host will automatically acquire the abilities unlocked by the practitioner opening the Sharingun.]

[Ordinary Uchiha users 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.]
