Fusion of Kamui, Single-Eye Eternal! Konoha 51.

Forget it.

Sasuke no longer had any desire to remain there. With a thought, he left Cell No. 1 and arrived at Cell No. 3, where Elder Nobuhiko was being held.

"Sasuke, what is the Mangekyo's Dojutsu...?" Seeing Sasuke appear, Elder Nobuhiko asked impatiently.

"Kamui!" Sasuke did not hide it, summarizing simply: "It is a Dojutsu that can distort space."

"It's actually a space-type Dojutsu?" Elder Nobuhiko gasped.

Although he had not yet seen the power of the Dojutsu with his own eyes, just from the words "distort space," he could easily judge the terror of this ability!

"Sasuke, can this Dojutsu be retained?"

Elder Nobuhiko knew that Sasuke had already fused with his Mangekyo, but he did not know it was only fused as a second eye; he assumed it was an overwrite, hence his concern.

"Of course, no problem."

Sasuke had already looked into the fact that abilities obtained through the Soul Space could be retained after fusion.

"That's good." Elder Nobuhiko breathed a sigh of relief.

If it couldn't be, his decision to let Sasuke fuse with his eyes would undoubtedly have made him a sinner.

Replacing the blinded Izanagi Dojutsu with pupil power in the left eye seemed nice, but compared to the space-distorting Kamui, it was far inferior. After all, Elder Nobuhiko, whose vision was limited to the current ninja world and who had never seen the Six Paths Mode or the Otsutsuki aliens, did not believe anyone could kill Sasuke in the future.

Ignoring Elder Nobuhiko further, Sasuke had come here for the sole purpose of fusing abilities, so he moved his mind.

'Extract and fuse Kakashi's ability!'

'Ding!'

'Fusing... Fusion successful!'

Sasuke closed and opened his eyes, which immediately transformed into scarlet Mangekyo. Within them, the pattern of the left eye's Mangekyo had already changed!

'Very good, I suppose this counts as a Single-Eye Eternal, right?'

Feeling the majestic pupil power in his left eye, he understood that this eye had evolved into an Eternal Mangekyo!

Recalling that he still had the Kamui eye gouged from Kakashi's socket, his gaze flickered:

'That eye is also a left eye, and it wasn't obtained through the Soul Space. Without Obito's bloodline connection, I can't even fuse it into my left eye...'

Time flew by, Konoha Year 51.

In the Soul Space.

Now nearly eight years old, Uchiha Izumi, who had been hiding in a tree, suddenly leaped down. The long sword in her hand slashed downward with a flash of cold light!

"Your movements are too telegraphic." Hearing the sound of air being torn behind him, Elder Nobuhiko, who had his hands behind his back, commented nonchalantly. He then stepped back with his right foot and shifted his body slightly to the right, as if taking a leisurely stroll.

"Oh no~" Watching the long sword slash past Elder Nobuhiko's body, Uchiha Izumi's pupils constricted as she realized her old momentum was spent and new force had yet to arise, leaving her unable to change her move.

Immediately, a fist shadow struck from bottom to top like lightning!

"Puff~!!!"

Suffering a heavy blow to her abdomen, Uchiha Izumi arched her back in pain, and then, with a "pop!", she turned into smoke.

"Shadow Clone..." Elder Nobuhiko raised an eyebrow, knowing in his heart that this was just a feint and the next attack would come soon. His eyes darted left and right.

A moment later, He seemed to have sensed something. As he pushed off the ground to leap backward, his right hand flipped, and several kunai shot out like cold stars, turning the arm that had burst from the ground where he had been standing into a pincushion!

It was Earth Style: Headhunter Jutsu... Elder Nobuhiko, who had made a precise prediction, didn't have time to be happy before the arm turned into smoke with another "pop." A strong sense of crisis came from above, making his scalp tingle.

'Above!'... He looked up abruptly.

'Izumi can create two Shadow Clones, so this must be the real body!'

He saw Uchiha Izumi had leaped directly above him at some point, her hands already finished with the hand seals!

"Fire Style: Dragon Flame Song Jutsu!"

'At the end of your rope? Knowing the gap in strength, you actually put your real body in mid-air where you can't borrow force to release a ninjutsu?'... Watching several dragon flames descend fiercely like meteors dragging tails of fire, Elder Nobuhiko looked dissatisfied, his hands moving like phantoms.

"Fire Style: Majestic Destroyer Flame!"

In the blink of an eye, the final "Horse" seal was formed. He took a deep breath, his chest swelling, and just before his body was about to be swallowed by the flames, crimson fire erupted outward!

Boom~!

The powerful Majestic Destroyer Flame instantly swallowed the dragon flames falling from the sky, but Elder Nobuhiko couldn't be happy at all, because at this moment, a sharp long sword was already pressed against his neck!

He saw Uchiha Izumi retracting her long sword with a smile: "Elder Nobuhiko, you lost!"

"Not bad." Elder Nobuhiko wasn't annoyed. Glancing at the Uchiha Izumi that had turned into smoke in the sky, he stopped his ninjutsu and stroked his beard with a smile: "By using your understanding of me, hiding the third Shadow Clone, and deliberately placing it in the air to induce a wrong judgment from me, you won by surprise. Izumi, you are very good!"

As the teacher who guided Uchiha Izumi's training every day, he knew her very well, and naturally, Uchiha Izumi knew his personality very well too.

If she hadn't thought that Uchiha Izumi could only create two Shadow Clones, he wouldn't have resorted to a ninjutsu clash at the end.

After all, a small Dragon Flame Song was something he could easily avoid.

He had only engaged in the ninjutsu clash because he was dissatisfied with Izumi placing her real body in the air, intending to teach her a lesson, but he hadn't expected his own psychology to be used against him by her.

"Thank you for the compliment, Elder Nobuhiko." Having won for the first time after so many sparring sessions, Uchiha Izumi's eyes curved into crescents as she smiled, though she quickly grew frustrated. "It's a pity that such a petty trick can only work once."

Elder Nobuhiko nodded; he certainly wouldn't be so careless next time.

Besides, the purpose of this sparring session was merely to test Uchiha Izumi's practical combat abilities. If not for the restrictions—such as being unable to use the Sharingan, unable to actively cast ninjutsu, and being limited to passive counterattacks—ten Izumis wouldn't have been able to defeat him.

After all, when faced with an absolute gap in strength, even the best tactics have no room to be deployed.

"Isn't a battle between ninjas supposed to be a one-time affair?" Sasuke, who had been watching from the sidelines, walked over and gave a thumbs-up. "Impressive, my Izumi-chan. You even managed to behead Elder Nobuhiko."

What 'my Izumi-chan'? Elder Nobuhiko is still right here... Uchiha Izumi rolled her eyes at Sasuke, but receiving the praise naturally made her heart flutter. This gesture, a mix of shyness and excitement, was somewhat charming and captivating.

Huh? Why am I thinking like that? I'm no lolicon! Sasuke was startled, his mind immediately conjuring images of several older women, among whom was Uchiha Izumi as she would look when grown up.

Wait? Isn't she thirteen years old too?

Sasuke gave up on trying to rationalize it.

What 'battle between ninjas is only a one-time affair,' what 'beheading'—to coax his little girlfriend, he doesn't mention a single one of the nearly hundred sparring sessions before this, Sasuke... Elder Nobuhiko looked exasperated.

Of course, these words could only be said in his heart; he had no intention of trying to educate Sasuke.

Now that Sasuke was a little over two and a half years old, his chakra meridian system had basically finished developing, allowing him to circulate chakra freely. Although his physical fitness was lacking and his combat experience was still very shallow, if he were to go all out—Single-Eye Eternal plus instantly entering Sage Fox Mode, followed by a Susanoo Setsuna Armor—he would be left with nothing to do but stare in helplessness.

Recalling his recent sparring experiences with Sasuke... he hadn't won a single time!

Every time he was about to win, Sasuke would just pull out a Susanoo Setsuna Armor, acting like a sore loser. It was truly exhausting...
