"You... how do you possess Kokugan and Sukunahikona?"
Although Isshiki was already dying, he still couldn't help but ask Itachi in disbelief. It was like Krillin unlocking Super Saiyan Blue against Super Saiyan God Goku and thrashing him.
"Think about it in the afterlife."
As Sasuke said this, he thrust the lightning spear toward Isshiki's head.
'You leave me no choice...'
Karma
Isshiki, facing certain death, used the last of his energy to pass his Karma Mark onto Sasuke.
PUCCHII
"Sasuke, how is it?"
Itachi, seeing Isshiki finally dead, asked Sasuke expectantly.
"Good... I got it, and there is a guy in my head trying to talk."
"Hmm... come here, I will take care of that guy."
Hearing that the attempt had succeeded, Itachi smiled in happiness. If this hadn't succeeded, he was about to reverse time... however many tries it took.
Though, he couldn't reverse time without restrictions. The first was that he had to fix a Time Stamp first, and then he could only reverse the future back to that Time Stamp. Second, the chakra or energy consumption for this was huge, and the greater the amount of time reversed, the more chakra it consumed. Lastly, the larger the affected space, the greater the chakra consumption. With his current strength, he could only reverse time by a few days for the entire world.
Though, Isshiki was really lucky to die on the first try, as the memories of everyone weren't erased when time was reversed.
"Niddhogg, take care of it."
Placing his palm on Sasuke's head, Itachi sent Niddhogg into Sasuke's spiritual dimension, letting it deal with Isshiki.
"Is it over?"
For a moment, Tsunade felt that Isshiki was nothing special, just like a genin in front of her. Although she knew that this was only her misunderstanding, she still couldn't believe it.
"Is this the gap between us?"
Adult Sasuke was also in a daze. He believed that he had reached the pinnacle of the Ninja World, surpassing Kaguya, Momoshiki, and the others... but there was still a gap between him and Isshiki. And Itachi, who had killed Isshiki as if he were a child, made his own arrogance seem laughable.
For a moment, he felt as though he had returned to the past during their genin days... when he had always wished to surpass Itachi and close that gap.
"Amado, you know the location of Daemon and Eida, right?"
"You know about them? I indeed do... here are the coordinates.. ."
Based on his assumptions, Itachi's timeline was still half a decade before the start of the Fourth Great Ninja War, and of course, his parallel self couldn't have created Eida and Daemon at that time. So... it meant Itachi had an ability similar to Senrigan, or perhaps even more powerful.
"You want to take them as subordinates?"
"Yes, but not for now... let's go."
Itachi answered while opening a Dimensional Portal and entering it.
Although Naruto and the others didn't understand the strange conversation between Itachi and Amado, they still followed him, entering a high-tech laboratory filled with sleeping chambers.
Daikokuten
With a wave of his hand, the sleeping chambers containing Daemon and Eida were transferred into his timeless dimension, safely storing both of these time bombs.
Sukunahikona
Daikokuten
A few seconds later, the entire research facility, along with all the researchers and scientists, was also sealed inside Daikokuten.
"Let's head to get the Ten-Tails next. Location?"
"Yes, it's..."
By now, Naruto and the others were numb. They felt like they had just lost a few billion dollars from a bank account they didn't even have.
Few Minutes Later
"Hey... I finally got to see the Ten-Tails."
Looking at the enormous monster roaring while its ten tails were pinned to the ground by ten massive black chakra rods, Itachi said curiously.
Back in his world... he still hadn't found this guy. Maybe it had been hidden by Isshiki in another dimension, because if it had been in the Ninja World... he would have found it instantly.
"And you are Code?"
Looking at the strange-looking boy, Itachi asked.
To be honest... he really didn't know why Code was so unlucky. He was always getting beaten or on his way to getting beaten, and had become the benchmark for showing off other characters' power.
It was the same with Kawaki, Boruto, Daemon, and even Jura. He was strong... much stronger than both Naruto and Sasuke without his limiter. But it was like how a Kage was worth less than a dog during the Fourth Great Ninja War. Code was just a dog in Boruto's much larger scale of power.
"Did you kill Lord Isshiki?"
Just moments ago, Isshiki had connected with him through his Karma to speak with him one last time, telling him about his death and to avoid fighting Itachi for now and instead become the will of the Ōtsutsuki... he just hadn't expected to meet Itachi so soon.
As Code said this, he stretched out his palm as it transformed into a larger claw. Just as he was about to swing it toward Itachi, space froze around him.
"You are much weaker than Isshiki. At least he was able to move under Frozen Space... but you still have your limiter, so it's expected."
Daikokuten
The next moment, Code was covered in black mist as he slowly disappeared into the timeless dimension, joining Eida and Daemon.
"Haaah... I am really tired of fighting one Six Paths Level opponent after another..."
Itachi stretched his arms while speaking in an exaggerated tone after dealing with Code.
"Big Brother, what will you do with the Ten-Tails?"
Seeing Itachi relax, Sasuke asked curiously. Would Mizumori have another pet?
"I will feed it to Yggdrasil."
Itachi answered while taking Yggdrasil, in its spear form, into his hand.
"Hey, you guys, move a bit farther away... I will let Yggdrasil take its true form."
Knowing that Naruto and the others weren't very familiar with Yggdrasil's true form, Itachi warned them.
Shadow Golden Lightning Form
Sasuke, on the other hand, immediately started running. Adult Sasuke, hearing Itachi's words and recalling the giant lightning tree from the parallel world, connected the dots and quickly informed the others, who also retreated.
Five Minutes Later
"Yggdrasil, happy meal."
Itachi also teleported a few kilometres away as he watched Yggdrasil grow.
To be honest, this was just an experiment for him. He wanted to see what would happen if Yggdrasil, a god made of souls, Yin Release, and Lightning nature, merged with the Ten-Tails, a collection of chakra from all natures. Would Yggdrasil gain another attribute, or even the attributes of the Sacred Tree?
Soon, a ten-kilometre-tall tree made entirely of bluish-white lightning stood like a mountain, destroying everything within the surrounding dozen kilometres.
"Is this his creation?"
Kurama, inside Naruto, sensed Yggdrasil's strength and spoke in disbelief. The Sage of Six Paths had been able to create the Nine Tailed Beasts by dividing the Ten-Tails, but... Yggdrasil was on another level, far stronger than even the Sage of Six Paths or Kaguya Ōtsutsuki, let alone Naruto and Sasuke.
Naruto and Sasuke also became solemn. They felt absolute death in front of Yggdrasil, as though they were merely genin facing Orochimaru. And Itachi had another one of these?
"ROAARRRRR—"
The Ten-Tails opened its eyes upon facing Yggdrasil and roared, but it stopped midway as dozens of Yggdrasil's roots pierced it from every direction, absorbing its chakra.
Ten Minutes Later
'Hmm... the strength hasn't increased much, but... it isn't a waste. Yggdrasil gained the Divine Tree's ability to grow by absorbing a planet's energy. If I can go to the Dragon Ball verse or the Marvel Universe... maybe it won't take too much time for Yggdrasil to reach Beyond Six Paths Level.'
As for danger... he wouldn't run into Beerus or Zeno just like that, right? He wasn't that unlucky. As for Marvel verse....as long as those multiversal or above beings do not interfere, he can be considered safe.
'Sigh... sometimes I really wonder whether my Zanpakutō is considered overpowered or a restriction... Maybe that's why Haruto had it in the future.'
