Since the plot hasn't changed, Orochimaru doesn't mind waiting a bit longer.
Things didn't go much differently from what he expected. While Urashiki was in the cave researching why the fishing line couldn't hook Naruto's Chakra, he accidentally discovered the Nine-Tails inside him.
However, the attempt to extract the Nine-Tails Chakra did not go smoothly, and he angered the Nine-Tails, Naruto to instantly enter Tailed Beast Chakra Mode.
Just as Urashiki was trying to find another way to seize the Tailed Beast Chakra, Jiraiya, Sasuke, and the others came looking for him again.
In the end, they could only watch helplessly as the other party retreated again.
He had considered taking advantage of the moment to go out and kill the guy, but while the idea was nice, reality didn't allow it.
If he doesn't kill the opponent in one go, he's not afraid of other abilities, but he's worried about his Yomotsu Hirasaka. If the opponent really gets away, he'll have nowhere to cry.
To be absolutely certain, he decided to wait and see. He had already waited so long, and now he should be more patient!
"It seems things are coming to a close! It's time to make preparations!"
Thinking of this, Orochimaru turned his gaze away from Naruto and his group, and then shut down the Black Void.
When I arrived at the outside laboratory, I saw someone washing test tubes.
"Kabuto, you'll be in charge of Sasuke's recovery for the next few days!"
Upon hearing Orochimaru's order, Kabuto stopped what he was doing and respectfully agreed.
Of all those who ambushed the Konoha pursuers that day, only he survived; Akado Yoroi, Mizuki, and the others died on the spot.
This outcome was both expected and reasonable for Orochimaru; a ninja without strength and intelligence would find it difficult to survive in this Ninja World.
They might as well make the most of their remaining time and energy; those who are alive will remember their contributions.
"Lord Orochimaru, may I look at those... scrolls?"
Orochimaru, who was about to leave, heard Kabuto's voice again and turned to look at him meaningfully.
Under Orochimaru's gaze, Kabuto immediately lowered his head, his heart pounding wildly.
"I'm sorry, sir, it was me..."
"Of course you can watch!"
Thinking Orochimaru would get angry, I was about to bow my head and admit my mistake when I heard his voice in my ear.
Upon hearing Orochimaru's affirmative words, Kabuto was taken aback at first, but then his joy was evident.
Just as he was about to express his gratitude, he heard Orochimaru continue:
"Whether you can understand it or not depends on yourself. I'm very busy lately and don't have time to teach you!"
Orochimaru not only doesn't hinder subordinates with a strong thirst for knowledge, but also provides them with opportunities when conditions permit.
And don't be fooled by the abundance of Ninjutsu scrolls here; some powerful Ninjutsu aren't included, such as the Uchiha's Izanagi, the Uzumaki Clan's Four Symbols Seal, Hashirama's Wood Release and Reaper Death Seal, and so on.
To learn these Ninjutsu, one not only needs to have sufficient personal qualities, but also needs guidance from someone.
Aside from him, a Ninjutsu genius, neither Sasuke nor Kabuto could have become self-taught here, so leaving them here would just be a waste of their time.
As for Kabuto learning the Impure World Reincarnation later, it was because Orochimaru's hands were not functioning properly in the Original Work, so he asked Kabuto to assist him in perfecting the technique. After seeing Orochimaru use it many times, Kabuto successfully learned it from him.
"Thank you, Lord Orochimaru! I promise I won't let my work be delayed...!"
Ignoring Kabuto's repeated expressions of gratitude, Orochimaru continued deeper into the laboratory. Since he hadn't triggered any system tasks, he was too lazy to spend time instructing him.
As he said, whether he can learn it or not depends on his own fate. Once the opportunity is given to him, he'll know whether it's useful or not after a try.
Back in the secret room, Urashiki continued to keep an eye on Naruto's movements. Just a few days later, Urashiki made a new move.
This time he seemed to be ready and approached Naruto again, but Naruto and his group were also prepared.
Because both sides were prepared to kill each other, neither side backed down halfway.
Orochimaru also witnessed the various abilities displayed by Urashiki's Rinnegan during the battle.
The first is time reversal. Urashiki's Rinnegan allows him to return to the position he was in a few seconds ago, thus avoiding attacks that are detrimental to him.
This is somewhat similar to Danzo's Izanagi, but the physical injuries cannot be changed, so it's not too overpowered.
Combined with his extraordinary senses, it's practically the Ninja World's version of Observation Haki.
The second is the Paper Crane Flash Step Technique, which is similar to Orochimaru's Sonido Technique.
Then there's the shape of his eyes. Initially, it was the Byakugan, then the Rinnegan, and finally the Six-Tomoe Rinnegan.
At this moment, Urashiki was using his red Six-Tomoe Rinnegan to fight fiercely with the others.
Orochimaru had to marvel at the variety of this guy's eyes, becoming increasingly envious the more he looked at them, wishing he could rush out right then and there.
The opponent's attack power did indeed increase significantly after activating the Rinnegan, which forced Sasuke to use the Uchiha's signature move Uchiha Suplex.
Urashiki was indeed subdued by this move and used the Ōtsutsuki Elbow Strike, the signature technique of the Ōtsutsuki Clan.
In the end, neither of them fared well. Urashiki was Sasuke, giving Naruto, Jiraiya, and Boruto a brief respite.
Soon, Urashiki, who had been injured, found Naruto again. Under the opponent's burst of power, Urashiki was hit directly by the Rasengan, and the others thought the battle was over.
Who knew that Urashiki had come back from the dead, would stand up again? Perhaps he was furious at being beaten so badly by a few mortals, or perhaps he realized that he couldn't deal with them with his current strength.
Urashiki finally unleashed his ultimate power, gouging out his two Rinnegan and stuffing them into his mouth. Combined with the Chakra he had previously plundered and stored in his fish basket, Urashiki immediately entered Celestial Crane Form.
His eyes turned into golden Byakugan, and a golden Rinnegan grew on his forehead.
Seeing this, Orochimaru knew that this was what he wanted, and he had secretly set the anchor point of the Black Void on the other party.
Normally, Urashiki might have noticed, but he was in a berserk state at the moment, and the anchor point easily locked onto him.
Despite using his signature moves, Urashiki showed signs of defeat under the combined attacks of Naruto and Boruto's Taijitu Rasengan, Jiraiya's sudden attack, and Sasuke's strongest Ninjutsu, Kirin.
Orochimaru, who was observing from the shadows, clearly sensed that Naruto's attack, combined with Sasuke's, had created a powerful Yin-Yang Release.
It seems that this power played a key role in Urashiki's defeat, but seeing this, Orochimaru knew he couldn't wait any longer.
The mantis stalks the cicada, unaware of the oriole behind; if you just watch the show, the other side will be utterly crushed.
In the blink of an eye, a black spatial rift, resembling the Yomotsu Hirasaka, appeared behind Urashiki.
Before Orochimaru could even react, Urashiki was blasted into space by the shockwave from below. The change happened so fast that no one could react in time.
Even though Orochimaru had already manipulated the Black Cavity Space to its limit, Urashiki's legs didn't have time to retract before being severed by the space.
As fireworks burst in the sky, Sasuke, Naruto, and the others breathed a sigh of relief.
Little did they know that they had only destroyed a small part of Urashiki's body.
However, not everyone noticed anything amiss. Sasuke's Rinnegan and Sharingan detected some clues through the bright light just now.
The change was fleeting, and upon closer inspection, he realized that Urashiki's aura had indeed disappeared, which put him at ease, as he assumed that the flash of light was simply due to overuse of his eyes.
After finishing his business here, Sasuke immediately used his Dōjutsu to erase Jiraiya and Naruto's memories of that time, and then he and Boruto used the "Plow" to return to their original timeline.
The curtain has fallen on their side, but Orochimaru, who is in the Black Cavity Space, has a lot to do!
