Experiment
While Obito Uchiha said that Vegapunk could never impersonate Madara Uchiha in his place, he was actually quite uneasy inside.
The intelligence Obito Uchiha to gain a deep understanding of Vegapunk's technological capabilities. He was no ordinary person; his scientific research had penetrated into unimaginable areas such as Kekkei Genkai and Chakra fusion.
If there is anyone who can research and integrate his Mangekyō Sharingan without damage or causing too much burden, then Vegapunk in front of us is probably the only candidate!
The opponent can even develop White Zetsu, so Wood Style and my inferior Sage Body obviously can't stop them. Plus, my eyes have fallen into their hands. In other words, they can easily transplant my eyes to become a powerful being with the exact same abilities as me.
With the same abilities, and even the same memories, the other party could easily imitate me, impersonate Madara Uchiha, and join the Akatsuki.
Obito Uchiha grew increasingly resentful, but Vegapunk waved his hand dismissively. "Whether I can do it or not, you can find out later. As for now, you're not planning to leave?"
"I..."
Obito Uchiha his fist, then relaxed it. Despite his immense resentment, he didn't believe he could fight Vegapunk in his current state. Moreover, as a loser, he was already lucky to have survived. He seemed completely powerless to stop Vegapunk from doing whatever he wanted.
Why did you spare my life? Aren't you afraid I'll expose your plans?
"Leaked! Leaked to whom? Those freaks in Akatsuki? Do you think they care whether the person behind the mask is a Tom, Dick, or Harry?"
"Besides, who are you now? What qualifications do you have to know such top secrets? And how many people would believe what you say?"
After opening his mouth, Obito Uchiha slumped down. Having lost his White Zetsu Cells and Mangekyō Sharingan, Obito Uchiha was merely an elite Jonin. While this level of strength might be considered decent in the Ninja World, it was clearly unconvincing against the freaks of the Akatsuki.
Who knows, I might get killed by the Akatsuki members who think I'm being too talkative after I've only said two words! If that happens, it would be such a shame to die.
"So what do you want to do after impersonating me? Are you also going to implement the Eye of the Moon Plan? Or are you eyeing those Tailed Beasts?"
After pondering for a moment, Obito finally spoke, and Vegapunk smiled and asked, "What? Didn't you seem indifferent to everything?"
Seeing Obito's face flush red, and seemingly about to become angry again, Vegapunk waved his hand and put down the mask he was holding:
"Don't worry, I actually have no interest in joining Akatsuki. That would just be lowering my status for me."
"By digging into your memories, I also know your deepest thoughts. The Eye of the Moon Plan is all a lie. You really want to use the Eye of the Moon Plan to create a world with your former crush, to escape the cruel reality... But what if I give you a chance to make up for the past and undo all the regrets?"
"What?" Obito Uchiha in surprise, his eyes widening.
"As long as you cooperate with me on a small experiment..."
Obito Uchiha was never considered a particularly intelligent person from childhood to adulthood. Even after he turned to the dark side and his intelligence improved, it was mostly due to information suppression and his unpredictable Kamui Ninjutsu. He was not a truly wise ninja.
After his conversation with Vegapunk, Obito Uchiha not only failed to discover Vegapunk's true abilities, but was also drawn to Vegapunk's experiments and eagerly wanted to become one of Vegapunk test subjects.
Yes, he is going to become the primary experimental subject for Vegapunk's Parallel World travels!
Although the previous Parallel World travel was successful, it was actually caused unintentionally by the turmoil of the Dragon Vein, and could not be considered a true experimental success.
After collecting a large amount of data, Vegapunk was finally ready to embark on autonomous travel. However, before that, he would definitely conduct some experiments to ensure that it was completely safe and worry-free before proceeding with autonomous travel.
According to Vegapunk's calculations, the best way to maintain one's safety during time travel is to possess spacetime abilities. Although he has now developed Time-Space Bubble technology, the Time-Space Bubble created by machines is far less useful and safer than the Kamui Dimension.
Most importantly, the small spaces developed using machines are rigid and cannot be truly controlled by humans. If the machines malfunction, it's truly game over.
Of course, besides Obito Uchiha, he also possesses two complete Kamui Sharingan from another world. If Cloning Technology were used, it would be possible to create ninjas who can use Kamui. However, unless he is willing to invest a lot of resources and time, the clones would be far inferior to the originals in terms of potential and ability.
As for directly using clones to open the Kamui Eye in batches... in reality, the real problem is not the technology, but more about resources.
With Vegapunk's current technology, he could easily create a Princess Kaguya Otsutsuki, but to make the clone unleash Princess Kaguya Otsutsuki's fighting power, it would be necessary to fill it with Princess Kaguya Otsutsuki's level of Chakra —according to Vegapunk's estimate, collecting all the Chakra in the entire Ninja World would be about enough.
Obviously, this is impossible unless Vegapunk can completely unravel the mystery of how various energies are converted into Chakra. Otherwise, cloning the Otsutsuki army will always be a false proposition.
If the secret of converting energy into Chakra were truly cracked, Vegapunk wouldn't need an army of Otsutsuki; he could easily defeat any opponent simply by accumulating astronomical amounts of energy.
Vegapunk could create the special Chakra needed to awaken the Mangekyō Sharingan, but the resources required would be so enormous that Vegapunk never waste so many resources creating these Mangekyo.
Besides the Kamui Eye in his hand, the only other person with spatial abilities is Hancock, the current Jinchuriki of Kaguya Otsutsuki.
Vegapunk didn't want Hancock to conduct such an experiment. Even with all his confidence in his technology, Vegapunk couldn't guarantee that his first experiment would be 100% successful. In this situation, Obito Uchiha, just happened to appear in front of him, which saved him the resources to create clones.
As for how to persuade him? Anyway, Obito Uchiha didn't have a deep understanding of Parallel World, so Vegapunk could simply say he was conducting an experiment to travel back in time. In order to save his beloved Rin Nohara, Obito Uchiha practically begged Vegapunk to make him the Unit 1 test subject.
