The shuriken struck the Heavy Xuan Ruler, producing a series of dinging sounds.
Thanks to the massive size of the Xuan Heavy Ruler, Sasuke blocked most of the attacks.
But many shurikens still pierced his hands and feet.
However, this little pain was nothing to Sasuke.
It wasn't even as bad as taking a punch from Naruto.
Adult Sasuke, who was panting, had sweat dripping down his forehead when he saw how reckless his younger self was.
'What the hell is up with him??'
'This fighting style isn't even Uchiha-like!!'
'It's downright insane!!'
'Why are you fighting like a brute…'
Adult Sasuke's expression darkened.
After all, the Uchiha Clan's fighting style is something he took great pride in, so this guy's reckless approach felt like a direct insult to him.
'Damn it!'
'If it weren't for the lack of Chakra...'
When Naruto saw that Adult Sasuke's breathing was somewhat like Kakashi's, he couldn't help but think to himself, 'He'd truly mastered the essence of his teacher.'
'Speaking of which...'
'How much Chakra does this Sasuke have?'
Naruto thought of this, patted his belly before activating the 'Big Fox Brand Chakra Detector'.
"Big Fox, check how much chakra that middle-aged uncle has."
"5…"
Kurama's voice was a little slow, but the number alone was enough to make Naruto speculate.
'500 Ma?'
'No, judging from his condition, he should only have 50 Ma.'
As he mused internally, Kurama spoke again, "4… 3… 2… 1"
"No more."
Kurama even let out a disdainful chuckle after saying this.
'Huh???'
'What's going on with this middle-aged Sasuke? Why is his Chakra constantly draining??'
'Look at Young Sasuke over there. He now has 600 Ma, which is twice as many as the current Kakashi.'
'Just relying on this value, Young Sasuke can crush the other party.'
'If this continues, middle-aged Sasuke will sooner or later be pinned to the ground and beaten by Young Sasuke.'
'A one-sided beatdown wasn't much fun to watch.'
'Just look at Young Sasuke, he hasn't even activated his three tomoe yet. It seems the battle was too easy to him.'
Naruto smirked at the thought. He took out a bottle of stamina potion and threw it to Adult Sasuke, who was not far away.
"Hey! Middle-aged uncle!"
"Catch."
"It restores Chakra!"
"If you don't go all out, you might die, you know?"
Snap…
Adult Sasuke raised his hand and caught it smoothly.
His face was full of confusion, but when he saw the familiar smirk on Naruto's face, he inexplicably drank it.
Sasuke stood where he was and did not continue to attack.
Hearing Naruto's words, he realized his opponent hadn't been fighting at full strength.
He also wanted to see just how strong the other party could be when serious.
Adult Sasuke drank the potion and the Chakra in his body was about to overflow.
Clenching his fists, he glanced at his younger self and suddenly let out a faint chuckle. His eyes burned with an overwhelming fighting spirit.
Now, he was going to show this younger version of himself that three-tomoe Sharingan could never defeat these eyes of his.
"How about we take this somewhere else?"
This was exactly what Sasuke wanted. They were currently inside the village, so they couldn't fight freely.
Putting away the Heavy Xuan Ruler, Sasuke nodded and said, "Fine."
Then, he turned his gaze toward Naruto, who was busy snacking on the sidelines.
"Alright, follow me."
Naruto put away his snacks and stools, then casually tossed out a portal. Without hesitation, Sasuke stepped through first.
Only Boruto and Adult Sasuke remained frozen in place.
"Y-Yomotsu Hirasaka!?"
"Dad, how could you use this!?"
Boruto's eyes nearly popped out of his skull. Beside him, Adult Sasuke had a similar reaction.
If not for having just seen his younger self, he'd almost suspect this Naruto was a member of the Otsutsuki Clan in disguise.
'Since when did Naruto know how to use this technique?!'
"Pick your jaw up off the floor. Follow me."
Naruto left those words behind before stepping through the portal, leaving Boruto and Adult Sasuke staring at each other in shock.
"Sasuke-san..."
"Since when could my dad use this?"
Adult Sasuke: "…"
'Don't ask me, I have no clue either!'
Adult Sasuke rolled his eyes before leading Boruto through the portal.
At this point, he wasn't as frantic as when he'd first arrived.
After all, with his strength now back in his prime, it would not be difficult to protect Naruto.
Upon passing through the portal, the scene before them changed and they came to a large open space with a three-story villa.
It is not difficult to tell from the slight burn marks on the ground that this place is a training ground.
At this time, Sasuke stood in the center of the open space with his back to Adult Sasuke.
When Naruto saw Sasuke oozing with edginess, the conversation between Ximen Chuixue and Ye Gucheng in his mind...
"So…"
"Who the hell are you?"
"Where did you get that Sharingan?"
Bang…
While Sasuke was speaking, he slammed the Heavy Xuan Ruler into the ground, then turned his head to glare at the other party with his crimson three-tomoe Sharingan.
Although the two of them had only exchanged a few moves earlier, he could immediately tell that this guy's fighting style came from his clan.
'This man's Sharingan was clearly not some secondhand ones like Kakashi's or Danzo's.'
Adult Sasuke remained silent after hearing the other party's words. He was considering whether to reveal his identity.
Because now, he truly sensed that something was off about this Konoha.
And the future of this world was most likely different from his own.
"He's literally future you!"
"You idiot!"
While Adult Sasuke hesitated, Naruto had already shouted from the sidelines.
When Sasuke heard this, he immediately felt unwell. He looked the other party up and down, then said with a look of disgust, "Bullshit! There's no way a weakling like that could be me!!"
"And he's also wearing such ugly clothes!"
"Plus, he's a cripple!"
Sasuke's words seemed like dancing in a minefield…
Every single one of them stepped right on Adult Sasuke's triggers.
Adult Sasuke drew his Kusanagi Sword and twirled it a few times elegantly, then pointed the sword at the arrogant brat.
The Eternal Mangekyo Sharingan in his right eye was also activated.
"You're no match for me."
"The gap between your three-tomoe and my eyes is insurmountable."
As he spoke the last line, a bitter smile flickered across Adult Sasuke's face.
'This scene is so similar to the time when I fought against Itachi...'
Seeing that flash of red, Sasuke instinctively reached for his bag of quicklime powder, but because the distance was too far, he stopped himself.
And that single motion made Adult Sasuke twitch.
When Sasuke saw Eternal Mangekyo Uchiha again, he could only marvel in his heart.
Then he immediately remembered that idiot Kakashi.
Pointing at the middle-aged uncle in the distance, he spoke to Naruto, who was watching from the sidelines, with absolute seriousness.
"See? I told you this isn't me."
"If you're going to fight, just fight… why are you monologuing?!"
Mid-sentence, Sasuke had already activated Three Thousand Lightning Movements at full power and appeared right in front of Adult Sasuke in an instant.
With the Heavy Xuan Ruler in his hand still covered in flames, he jumped high and smashed down at the middle-aged uncle's head in a crushing arc.
"So fast!!"
Boruto, who is sitting on the sidelines, exclaimed in awe.
At this moment, he had already simulated in his mind the speed of Adult Sasuke and this black-robed Sasuke.
The results of the comparison are astonishing...
Because he realized this black-robed Sasuke was even faster than the Adult Sasuke he knew!
And most importantly...
He had never seen a Ninjutsu like this in any textbook.
"Dad, what kind of Ninjutsu is that..."
Ever since Boruto knelt down to acknowledge his 'Dad', he now had zero psychological barriers to calling Naruto Dad.
Hearing his cheap son's question, Naruto felt a deep sense of exasperation.
After all, who could've guessed Sasuke actually managed to master Three Thousand Lightning Movements...
Despite his internal griping, he patiently explained to Boruto.
"This technique...?"
"It's Uchiha Xiao Yan's original Ninjutsu - Lightning Release: Three Thousand Lightning Movements."
"Wow… that's amazing!"
When Boruto heard the name of this technique, admiration filled his eyes.
Meanwhile, on the training ground, Adult Sasuke's method of countering was simple...
Just as the Heavy Xuan Ruler was about to connect, a purple skeleton made of Chakra enveloped his body, effortlessly blocking the attack.
"W-What the hell is that!?"
