As an Uchiha I became the Jinchuriki of Senju Tobirama

"Don't worry, Yakushi." Kazuki blinked and said softly: "I trust in your loyalty to me, and even more so in your faith in the future of the Root and the village. I know you were very harsh with him, weren't you?"

"You don't have to feel guilty. We all carry a past that is difficult to let go of, but the past is just that: the past. The important thing is to face the future with a new attitude."

Kazuki patted him on the shoulder, showing a calm smile. "Go, Yakushi, don't feel psychologically burdened."

Yakushi took a deep breath, silently grateful that he had confessed the truth. Trying to hide something from Kazuki had been a mistake from the start

As Yakushi walked away, Kazuki remained pensive, reflecting on his first Mangekyo Sharingan techniques obtained…

Amaterasu was an extremely powerful technique.

On the other hand, Susabi, a technique capable of foreseeing the future, was even more intriguing.

The accuracy of this technique depended both on the temporal proximity of the predicted event and on factors that could interfere in the future.

Kazuki knew that trying to foresee the fate of the shinobi world with this technique would be unreliable. Too many disruptive elements existed: The Sage of the Six Paths, Otsutsuki Isshiki, Otsutsuki Kaguya, Uchiha Madara, Senju Hashirama…

Even the Otsutsuki who lived outside this world.

These entities, superior to any ordinary Mangekyo Sharingan, could significantly interfere with Susabi's accuracy. And if we added to that the Great Toad Sage with his own prophecies...

Although Kazuki did not have a good impression of the Great Toad Sage, he recognized that his position was far above that of a mere Mangekyo. After all, he was an existence that could chat and laugh with the Sage of Six Paths.

Kazuki can't help but be a little curious. With Uchiha Fugaku's temperament, he will definitely want to spy on him after getting this eye technique...

He just doesn't know what he'll see with Susabi.

Kazuki was lost in thought. "Predicting the future of the shinobi world is pointless. Or perhaps not so much… In some cases, a prophecy can be an excellent excuse."

"The shinobi world was too complex, filled with forces that constantly interfered. Trying to foresee the future of a Kage-level shinobi is also of no use to me."

Frowning, he began to think of more practical ways to use Susabi. Moments later, his expression changed, breaking into a slight smile. He had found the perfect purpose for this technique.

Using Susabi to gain power or predict the future might attract hidden enemies. However, if he used it as a treasure radar, its usefulness would be exceptional.

Inanimate objects, unlike living people, did not change or increase their power, which greatly increased the precision of the technique.

Activating his Sharingan, the three tomoe quickly spun in Kazuki's eyes before returning to their normal state. Kazuki had not yet awakened the Mangekyo Sharingan, he had only obtained the techniques.

As the Susabi technique was activated, Kazuki focused on finding the location of the Yata Mirror and the Sword of Totsuka.

Images of various villages, mountains, and cliffs of the shinobi world emerged in her mind, until finally the image of a gourd and a small shield formed. A strange connection of attraction began to form with Kazuki.

"In the Land of Frost?"

Meanwhile in Kazuki's mindspace, Tobirama looked around in fear, uneasy about the sudden increase in Kazuki's ocular power. He had also sensed that Kazuki had used a dojutsu he was unaware of.

Although Tobirama wanted to ask him, he didn't know how to approach the subject.

Kazuki, meanwhile, stared at a nearby wall. The tomoe of his Sharingan spun, and a black flame began to burn on the wall.

Kazuki stretched out a hand to feel the heat and nature of the flames.

Seeing the familiar black flame, Senju Tobirama's heart trembled, and he couldn't help asking: "Kazuki, have you opened the Mangekyo Sharingan?!"

"Have I awakened the Mangekyo Sharingan?" Kazuki said in confusion: "Why did you think of saying this, Tobirama? Are you suspicious of Uchiha again?"

Tobirama looked at the black flame on the wall with a complicated expression.

"Amaterasu is one of the exclusive techniques of the Mangekyo Sharingan, and can only be used by those who awaken it..."

Tobirama was about to give an explanation when he saw Kazuki crack a smile as he controlled the black flames with ease.

A thin thread of black fire curved and danced in the air, slowly forming the words: Senju Tobirama.

Tobirama's face froze. Watching Kazuki use a technique that required enormous ocular power, for something as trivial as writing his name, left him completely disoriented. For a moment, he didn't know what expression he should show.

"Understood... Then, your second Mangekyo technique is Kagutsuchi."

Amaterasu was one of Izuna's Mangekyo techniques and had caused Tobirama countless problems in the past.

As Tobirama pondered the origin of the Kagutsuchi, Kazuki interrupted his thoughts.

"Tobirama, if you don't understand, you better not talk nonsense, okay?"

Kazuki pointed at his three-tomoe Sharingan as he summoned Amaterasu again. The black flames burned brightly, but the three tomoe were still clearly visible, not forming the complex patterns characteristic of Mangekyo.

"In my opinion, the Kagutsuchi you mention is nothing more than an extreme form of chakra manipulation of a fire-type nature. Why would it be necessary to awaken the Mangekyo Sharingan to use it?" Kazuki spoke with natural confidence. "With a sufficiently advanced mastery of Fire Release, you don't need a dojutsu to perform it."

Kazuki, who possessed mastery of Madara's Fire Release and the Eye of the Snake ability, can claim such a thing.

Kazuki continued: "If you say that Amaterasu is unique to Mangekyo, it makes some sense."

Tobirama took a deep breath. Do you understand Uchiha, or do I understand Uchiha?

No one knows the Uchiha clan better than him!

He has seen Izuna use Amaterasu so many times, how could he not know it?

Even seeing the Kagutsuchi that Kazuki had displayed, Tobirama assumed that Izuna had been hiding that technique, and simply didn't get the chance to use it before he killed him.

"Leaving aside the Kagutsuchi for now, how do you explain the Amaterasu you used?"

Tobirama stared at the three tomoe in Kazuki's eyes, and was a little confused for a moment, muttering to himself: "The Mangekyo Sharingan… only awakens when an Uchiha experiences intense negative emotions. It is an evil eye that arises from a special chakra generated in the brain…"

"Are you reciting a textbook, Tobirama?" Kazuki shook his head. "It's like learning any other ninjutsu. If you have enough chakra and master the necessary form and nature transformation, you can naturally learn any ninjutsu."

"The same applies to dojutsu. If the eye power is strong enough, understanding certain techniques should not be so complicated."

Senju Tobirama was silent.

What Kazuki said seemed to have some logic… but at the same time, it sounded absurd.

He had investigated many Uchiha and had never seen anything like this.

While in the middle of a conversation with Uchiha Yakushi, he was stunned for a moment, and then he had already mastered the Mangekyo techniques that many Uchiha yearn for...

Isn't this a joke?

Tobirama complained in his mind: 'Damn Izuna! In order to avoid further misunderstandings with Kazuki, I can no longer suppress your chakra openly and taking advantage of this you are using my chakra to increase your ocular power!'

'Could it be that the bastard Izuna's chakra has some affinity with mine, and that's why Kazuki can use Izuna's techniques without having awakened the Mangekyo?'

Although the idea irritated him, Tobirama also felt relief.

He had thought that Kazuki had opened Izuna's Mangekyo, but fortunately he was still a three-tomoe Sharingan.

This also proves that his power neutralized Izuna's pupil power. Because even though Kazuki learned his Mangekyo technique, he did not awaken the Mangekyo...

'Damn it! My power isn't something you can just take away so easily, damn Izuna!'

Tobirama exhaled deeply and warned seriously: "Kazuki, you must use these two dojutsu with extreme caution. Mangekyo-level techniques greatly drain the power of the eyes. Prolonged use can lead to irreversible blindness."

"These techniques are an ace up your sleeve, but you shouldn't blindly rely on them."

Kazuki blinked, and once again activated Amaterasu. The black flames twisted in the air until they formed a line of text that responded to Tobirama: [Really? I don't believe you!]

Tobirama took a deep breath. How could this brat be so stubborn?

If Kazuki won't listen to reason... maybe he should consider other options. Tobirama began to think of a way for Shisui to give up his eyes so that Kazuki could replicate Madara's path.

But then Tobirama stopped, bewildered.

In his memories, when Izuna used Amaterasu he suffered from tears of blood as a result of overusing his eyes.

However, Kazuki's eyes were completely normal. They didn't even show any redness.
