Few Months Later — Mizumori Year 3 — December
"Sasuke, you already know everything about the Ōtsutsuki Clan and Karma. With that, you can rapidly grow and reach Six Paths Level by my age. But with that comes immense risk. I will ask one last time, are you READY?"
Itachi, standing on the center of Mizumori Lake, looked at Sasuke like a commander addressing his soldier.
"YES SIR!"
Sasuke's confident voice earned Itachi's appreciation.
"Hmm. We will now go to another parallel world in the future timeline. There, Ōtsutsuki Isshiki, who was killed by me and gave me Karma, is still alive. I will beat him to the brink of death, and you will kill him. I have already explained the precautions many times, so I won't waste more time."
Space-Time Dimensional Portal Open
As Itachi murmured, a strange colorful portal appeared in front of the two of them, connecting to Sasuke of the parallel world. Now, with his strength, he could easily traverse impossible distances just like before, as long as he had the coordinates of the location.
As for the Boruto part already being done since more than a year had passed since Sasuke's departure... well, it would only happen if both timelines were synchronized. Itachi and Sasuke were going to the future, so the time spent in their present didn't matter. {It's like in Doraemon: a year has passed in the 20th century, but Nobita can still travel to the future at the same point his past self could a year ago.}

Parallel World 001
Konoha — Boruto Timeline
Konoha Hospital
A colorful portal opened inside a hospital ward as Itachi and Sasuke stepped out.
"Big Brother... is this me?"
Sasuke looked at the hospitalized adult Sasuke and asked with difficulty. Although he had seen adult Sasuke fighting Urashiki a year ago, he hadn't met him personally. He still had expectations for his parallel future self, but the moment he saw him, he found him hospitalized.
"Who are you?"
Shadow Paralysis Jutsu
Nara Shikamaru, seeing the sudden appearance of Itachi and Sasuke, asked while using his jutsu to bind the two of them. Sakura also took her stance, standing in front of Sasuke, ready to attack at any moment. Dozens of ANBU also appeared around the bed with kunai and swords unsheathed.
SNAP
"FREEZE "
With a snap of Itachi's fingers, the space inside the room froze except for himself and the two Sasukes. As for the Shadow Paralysis Jutsu... well, it didn't work for even a millisecond.
RAPHAEL'S INVOCATION
Itachi ignored the crowd and formed a green orb in his hand. When it reached the size of a tennis ball, he pushed it toward Sasuke.
'Move... I have to protect Sasuke... Move.'
Sakura seeing Itachi attacking adult Sasuke tried her absolute best to break free, but ultimately, the power of friendship doesn't work against Itachi.
A second later, the green orb merged into adult Sasuke as he started to glow green. His wounds rapidly healed as new flesh and organs formed, replacing the damaged ones.
A few seconds later, adult Sasuke finally opened his eyes.
"Yo, Sasuke! The first time we met, you were beaten up, and now you're even unconscious after getting beaten up... If I didn't know you didn't have that kind of hobby, I would have misunderstood something."
Seeing Itachi's smile, adult Sasuke didn't feel relieved. After Itachi killed Urashiki in the other timeline, Sasuke had taken Boruto and escaped to his own timeline with the Otsusuki artifact after seeing Itachi's disappearance. He had expected never to see Itachi again, but... Itachi was back.
"Did you find Karasuki in your world?"
This was the only reason adult Sasuke could think of for Itachi's arrival.
"Well, I did find it, but I came here with the help of the mark on your body."
With his Domain Expansion covering a planetary range, it was easy to find the turtle ( time travel Otsusuki artifact ), and he had found it more than a year ago. But there was no need to use it to travel here.
"Sigh... so what do you want?"
Sasuke sighed and asked. If Itachi wanted to destroy Konoha, then he would have to get past him, and he still had to rescue Naruto.
"Well, I said it before, I do not have any interest in destroying Konoha in other timelines."
Seeing the huge "misunderstanding" in adult Sasuke's eyes, Itachi spoke innocently.
"Big Brother... didn't you destroy Konoha in the previous timeline?"
Just then, Sasuke interrupted Itachi and spoke innocently.
"I knew it!"
Adult Sasuke, hearing this, immediately activated his Rinnegan, fully alert for Itachi's next move.
Itachi, on the other hand, looked at the younger Sasuke, who wore a playful expression, with a twitch. Well, Sasuke didn't want Itachi to fool him—not even his parallel self—unless it was necessary.
"Ahem, I did destroy Konoha in another parallel world... but it's because they deserved it. They were about to kill the Uchiha Clan."
'They were about to kill them... so they got destroyed... We have already killed them... What will happen to us?'
By now, Shikamaru had already understood the situation. These Uchiha brothers were from the parallel world that Sasuke and Boruto had traveled to last year. He didn't know how they had traveled, but they were bad news... especially since Naruto was gone and Sasuke was out of chakra, even though he had been healed by Itachi.
"Well, Sasuke, although I healed you, your mental trauma is still there. Let's talk after you've rested."
Seeing adult Sasuke acting like a mama hen protecting her chicks, Itachi sighed and smiled.
"Let's go, idiot."
"I am not an idiot."
"Whoever responds is an idiot."
"Hmph."
While Itachi and Sasuke were having their usual argument, a purple portal formed before them, and both of them stepped into it.

Other Dimension
"Big Brother, where are we?"
Sasuke looked at the purple sky and barren ground in confusion. He had thought they would roam around Konoha or rest in a hotel, but this clearly wasn't the Ninja World.
"Well, some children are rescuing their beloved Hokage... Why don't you have a good training session before fighting Isshiki?"
Itachi pointed toward Boruto, Sarada, Mitsuki, and Kawaki battling Boro.
"Hmm, that guy does feel strong... Very well. I shall save them."
Chidori Style: Chidori Body Flow
One Second Later
Lava Style : Planet-Branding Blast
"Boruto, get out!!"
Looking at Boruto still suspended in the air while Boro spat out a massive column of acid, Sarada shouted. Kawaki rushed toward Boruto to help, but someone was faster.
Chidori Style: Chidori Spear
The next second, Sasuke appeared beside Boruto in midair and threw the Chidori Spear toward the incoming river of acid, splitting it into two.
"Elite Jōnin Level strength, huh? You have improved quite a bit, but that's only because of Karma."
Sasuke placed Boruto on the ground and said with analysis. During the Dawn Competition, Boruto neither used Karma nor knew how to use it, so his strength had been at most Elite Chūnin to Special Jōnin. This leap in strength was quite impressive.
"You are... Sasuke?"
Boruto, seeing the face of his savior, was astonished. He hadn't expected to meet this Sasuke again, much less be saved by him.
"You..."
Clearly, Boruto wasn't the only one surprised, as Sarada stared at Sasuke in astonishment. She had seen young photos of Sasuke, so she recognized him, although there was a slight difference in their clothing styles. She also heard Boruto's words, making her even more confused since she knew nothing about Boruto's parallel-world journey.
"Hmm? An Uchiha? Three Tomoe at this age is impressive... but why is she wearing glasses?"
Seeing Sarada, Sasuke asked Boruto in confusion.
'An Uchiha wearing glasses? Is this world so unique?'
"Well... she is... Mr. Sasuke's daughter."
Boruto, seeing Sasuke's young face, answered in a strange tone.
"Oh..."
Now Sasuke became awkward. He suddenly had to face his daughter—well, not his daughter, but still his parallel world's daughter—making him unsure how to act. His own family didn't have a daughter, nor did Shion have a father, so he had never truly seen a father-daughter relationship.
How should he act ? { Five Marks Question }
"Let's deal with this guy first."
Seeing Sarada's questioning gaze, Sasuke coughed and changed the topic.
Shadow Golden Lightning Form
The next moment, the blue lightning surrounding him turned golden as his strength reached Kage Level.
He couldn't lose face in front of his parallel world's daughter, could he?
"Sasuke, be careful of that black mist. If you stay in it for too long, you'll become paralyzed."
Seeing Sasuke use Golden Lightning, Boruto became excited and warned him.
He had seen Sasuke use Golden Lightning before and had watched him compete with the Ender Dragon for a move or two. This Boro was much weaker than the Ender Dragon, making the rescue mission seem far more hopeful.
"Hmm."
Lightning Spear Style: First Form: Thunder Cannon
The next moment, in Sarada's Three Tomoe Sharingan, Sasuke transformed into golden lightning and appeared before Boro in less than a second, as the golden spear formed a head-sized hole in Boro's chest the next instant.
"Careful!"
At that same moment, as Sarada gave her warning, Boro, seemingly unaffected by the head-sized hole in his chest, raised both hands to crush Sasuke.
Rasengan
Chakra Energy Blast
Fire Style: Fireball Jutsu
Hidden Shadow Snake Hands
Boruto rushed forward with a Rasengan in his hand. Kawaki raised his palm and fired a red energy blast toward Boro. Sarada and Mitsuki also attacked with everything they had to force Boro back.
But Boro ignored all those attacks and continued attacking Sasuke as if Sasuke had done some unspeakable things with his mother. A huge amount of black fog also surrounded him, trying to paralyze Sasuke.
"Heh, you overestimate yourself."
Seeing Boro trying to punch him, Sasuke stabilised himself with lightning speed and impaled the golden spear into Boro's stomach.
PIERCE BOOM SHRRRRR BOOM BOOM
The next second, numerous explosions happened one after another as Boruto was blasted away by the shockwaves.
Well, Kawaki and Team 7 had good tactics. Kawaki's and Sarada's attacks would force Boro to leave Sasuke. Mitsuki would provide crowd control and try to poison him, while Boruto would follow up with his Rasengan. By that time, Sasuke would have joined the battle as well... It's just that Boro didn't move.
As for why Boruto was blasted apart ? Previously, Sasuke who was hit exploded into golden lightning, while other attacks continued one after another. Boruto, with his shōnen protagonist instincts, forgot about his own safety and rushed into the explosion to save Sasuke.
If not for Mitsuki using his Hidden Shadow Snake Hands to pull Boruto back at the perfect moment... Momoshiki would have awakened.
"Fatherrr!"
"Boruto!"
Seeing Boruto's injured body, Mitsuki rushed toward him. Sarada, on the other hand, had tears in her eyes... Her father, although younger, had seemingly died right before her.
"Are you guys idiots? In my Shadow Golden Lightning Form, I have much faster reaction speed and speed than the Fourth Raikage. That was my Golden Lightning Clone. That's why I didn't bother escaping."
Seeing Sarada's eyes filled with hatred toward Boro, Sasuke spoke with a strange expression.
'It seems she isn't very bright... Didn't she see me using the Lightning Clone Jutsu with her Three Tomoe Sharingan?'
Well, this was Sasuke's misunderstanding. Previously, whenever he sparred with Itachi, Itachi always used his Three Tomoe Sharingan and was able to see all of his moves, so Sasuke didn't expect Sarada to be unable to see them.
In his other battles against fellow Uchiha, with his Kage-level strength in Golden Lightning Form, most of his opponents had Mangekyō Sharingan who could react to the Golden Lightning Clone Explosion, which only reinforced Sasuke's misunderstanding.
'This guy is much stronger than Boruto.'
Sasuke ignored the surprised Sarada and looked towards Kawaki in surprise.
