Cannot Be Looked At Directly

Boom!!

The mental space was instantly divided into two colors.

A black and purple aura surged like waves, attempting to engulf the blazing, deep-red volcano.

"Who are you!"

"Why do you possess such terrifying chakra!"

"Why... do you know my name!"

The Four-Tails felt the extreme coldness emanating from that chakra. This feeling...

It had encountered Indra in his youth, that ancestor of the Uchiha clan.

The purity of the Yin Release from this brat before it was already extremely close to Indra's back then!

That was the direct bloodline of the Six Paths old man; how could this brat possibly...

Kagami Uchiha stepped directly onto the Four-Tails' head, his mental energy manifesting as a giant Fuma Shuriken.

Humans didn't see Tailed Beasts as guardians, but as natural disasters that needed to be feared, dreaded, and sealed.

Kagami Uchiha knew the truth, but he wouldn't try to reach an understanding with the Tailed Beasts like Naruto.

Because he knew very well that he was the type of person Tailed Beasts hated the most.

He wouldn't see Tailed Beasts as partners; he just wanted to borrow their power.

The Fuma Shuriken spun rapidly, possessing extreme cutting power, and slashed mercilessly towards the Four-Tails' neck.

"You damn brat! Don't underestimate me!"

"Lava Release - Flower Fruit Mountain!"

The Four-Tails desperately struggled against its chains, releasing extreme heat from its entire body, forming a sea of lava.

Boom!!!

The lava exploded violently, managing to withstand the giant Fuma Shuriken.

However, this stalemate didn't last long. The chilling Dojutsu Power was continuously amplified until the Fuma Shuriken grew to hundreds of meters in size!

Boom!!

The Four-Tails' body crashed to the ground. The Fuma Shuriken acted like a cutting disc against stone, pressing down bit by bit.

"A natural enemy..."

Because he was borrowing Sukuna's Cursed Energy, the seal couldn't be completely closed, and he also witnessed Kagami Uchiha's actions.

The basic abilities of the Sharingan were similar to the Six Eyes, which gave Sukuna a reference point.

However, Sukuna felt that even Gojo Satoru, who possessed the Six Eyes, wouldn't have such an easy time dealing with this monster.

Judging solely by the energy he witnessed, this monster was far stronger than a Leak Pot of the same attribute.

Unlike the Six Eyes, of which there was only one per generation, this brat's clan had many of these eyes...

Could this clan be the legendary Divine Race?

Did they possess a special suppression against monstrous beasts?

Was his arrival here also because an ancestor of this clan sealed him into this brat's body?

Sukuna never gave up on escaping, pondering information about Kagami Uchiha.

There was one point he guessed incorrectly.

Normally, the Uchiha's Three Tomoe would be ineffective against Tailed Beasts.

Even if it evolved into a Mangekyo, it might be useful against ordinary Tailed Beasts, but controlling the Nine-Tails would be impossible.

Obito's ability to briefly control the Nine-Tails might also have been a residual method from Madara.

The most important factor in the use of any power was the user.

The ones who could restrain the Nine-Tails were Hashirama and Madara, not Wood Release or Mangekyo.

The reason Kagami Uchiha could suppress Tailed Beasts had already been answered by the Nine-Tails previously.

Dojutsu Power!

Dojutsu Power was a type of chakra, but it focused on mental energy.

The so-called Mangekyo was essentially an evolution that occurred when mental energy reached a critical point.

With Kagami Uchiha's current Dojutsu Power, he had already surpassed that point and could evolve into a Mangekyo at any time.

However, he hadn't yet resolved the drawbacks of the Mangekyo.

Excessive use would lead to blindness.

Why couldn't Mangekyo Dojutsu Power recover?

It was because the Uchiha clan members' bodies were too weak compared to the Mangekyo Sharingan.

Indra, the eldest son of the Sage of Six Paths, naturally had no such concerns. It was just that his descendants did not possess bodies capable of bearing the Sage's Eyes.

Even Uchiha Madara, in his old age, could not bear the Rinnegan.

To prevent the Rinnegan from drying out, and fearing being drained by it himself, he chose Nagato, a descendant of the Uzumaki clan, as a vessel for the eyes.

According to Kagami Uchiha's estimation, it would take at least another year for his body to withstand the pressure of the Mangekyo.

It would be best to catch a White Zetsu quickly and directly intercept Uchiha Madara's research findings, thereby obtaining Hashirama's cells for himself.

Obtaining Hashirama's cells would not grant him the Rinnegan; that was exclusive to the Sage's son, as Obito had already proven.

However, it would definitely greatly alleviate the side effects of the Mangekyo Sharingan.

Otherwise, given the frequency with which Obito used his Mangekyo Dojutsu, even Kamui, being power-efficient, wouldn't have been enough; he would have gone blind long ago.

Of course, if there were any life-threatening dangers, he could distinguish between dying and suffering some physical damage.

Simply put, he was suppressing his realm, hoping for a more perfect advancement.

Moreover, he had another plan that might solve this drawback...

Reverse Cursed Technique.

It converts Cursed Energy into positive energy through its manipulation, thereby achieving a healing effect.

Translating this to Chakra, it would be converting Yin-release Chakra into Yang-release Chakra...

This concept was feasible, but the difficulty would undoubtedly be much greater than simply reversing Cursed Energy.

The Four-Tails, cut by the Fuma Shuriken, let out a tragic roar and cursed vehemently.

It was useless.

If he hadn't sealed it, he might have been able to contend with Kagami Uchiha. But now...

It was like two people, one holding a whip and the other tied up; it wasn't an equal fight from the start.

An endless stream of the Four-Tails' Chakra was cut off and collected by Kagami Uchiha, while scorching heat waves also emanated from his body.

Tailed Beasts were the embodiment of Chakra. The Four-Tails, having a large amount of its Chakra drained, visibly became emaciated.

Kagami Uchiha could clearly sense that Tailed Beast Chakra, whether in "quality" or "quantity," was on a completely different level compared to ordinary ninja Chakra.

Especially within the Four-Tails' Chakra, his understanding of Lava Release, after just this brief contact, gave him an idea for developing Lava Release.

Just then, a furious roar echoed in the empty Mental Space.

"Kai!"

Kagami Uchiha felt a powerful pressure forcing him out of the Mental Space.

With one last glance at the emaciated Four-Tails, he said indifferently:

"Stop pretending to be the Monkey King, you red-haired gorilla."

"Goodbye, Four-Tails."

Pretending?

My name was given by the Sage of Six Paths!

Why are you so hostile towards me!

Gah...

The principle of Genjutsu mainly involves interfering with another person's Chakra flow using one's own Chakra, thereby affecting the target's five senses.

The reason perfect Jinchuriki are immune to Genjutsu control is that the Tailed Beast will help break the illusion when the Jinchuriki is controlled.

Conversely, if the Tailed Beast within is controlled, the Jinchuriki can also break the Genjutsu.

Kagami Uchiha's main objective was to enter the Mental Space where the Four-Tails was imprisoned. Genjutsu couldn't control Roshi for long.

The definition of a perfect Jinchuriki is to make peace with the Tailed Beast within, something Roshi had not achieved.

It was just that his own Kekkei Genkai was Lava Release, the same as the Four-Tails, and he had forcefully seized the Four-Tails' power.

It was like when Naruto first defeated the Nine-Tails and gained its Chakra.

It was akin to a slave turning into a master.

As soon as he regained consciousness, he noticed the abnormality within his body. Sensing something was wrong, breaking the Genjutsu first was definitely the right move.

Whoosh—

A puff of smoke reappeared on the giant eagle, revealing Kagami Uchiha.

He looked down at Roshi, who had already dispelled his Tailed Beast Transformation.

It seemed the Four-Tails wouldn't be able to recover its Chakra anytime soon.

"You just now..." Aburame Shibi seemed to have thought of something. The scene just now was very similar to a secret technique he had seen a senior perform.

"Spirit Transformation Technique with no physical weakness!"

"Don't make it sound like I'm copying you, Shibi-senpai."

Kagami Uchiha turned his head to look at him, "With such a great opportunity just now, don't tell me you didn't use your Destructive Insects to attack him."

"Uh..."

Aburame Shibi, wearing his sunglasses and mask, hid his embarrassment well.

"Sorry, it all happened so suddenly... Actually, you only disappeared for a few seconds..."

"No need to explain."

Clang—

Kagami Uchiha drew his sword and leaped down, charging straight at Roshi.

"I'll handle the Jinchuriki, you just watch from there."

"As a useless bystander."

Cannot... look directly at the Sharingan.

Having experienced what happened earlier, Roshi dared not show the slightest contempt for this Uchiha youth.

No matter how unwilling he was, facing Kagami Uchiha who flew towards him, he could only lower his head and avoid eye contact.

It was like offering his neck for slaughter.
