"As expected, it's good for one's reputation to spread. Look, new experimental materials have been delivered right to the door!"
Vegapunk, sitting in the laboratory, smiled as he watched Kakashi Hatake drag in the experimental materials from the Land of Water, and said quite happily.
Kakashi Hatake rolled his eyes but didn't say anything more. As a genius Ninja known for being calm and clever, he didn't want to end up on the experimental table again.
Vegapunk's arrival might be a good thing for the Land of Snow, but it wasn't for Kakashi. In terms of value, Kakashi was far superior to those Snow Ninjas.
Perhaps in terms of combat power, the numerous Snow Ninjas with their unique climate advantage held the absolute upper hand against Kakashi, but in terms of pure potential and the knowledge stored in his mind, Kakashi surpassed these Snow Ninjas by countless times.
Consequently, at the beginning, Kakashi became a regular on Vegapunk's experimental table. Although Kakashi himself was not very willing, given the massive gap in strength, he was quite sensible.
Vegapunk's laboratory happened to be located in the crater of a dormant volcano. Relying on the continuous geothermal energy, a part of the quantum brain's capabilities had been activated. Even if it was only a part, its computing power already exceeded human imagination. Using the quantum brain, Vegapunk had already analyzed all the Ninjutsu in Kakashi's mind.
The current Kakashi was not yet that Copy Ninja who possessed a thousand Ninjutsu, but he still stored dozens or even hundreds of types of Ninjutsu. It could be said that he enriched Vegapunk's Ninjutsu database all at once.
As for whether doing this would cause trouble or offend Konohagakure... Given the environment of the Land of Snow and the strength of Vegapunk and the others, it was impossible for Konohagakure to make a big fuss and risk their lives for the Ninjutsu in Kakashi's head.
However, if Vegapunk were to take Kakashi's Sharingan, there might be some trouble, but it wouldn't cause a war—the Land of Snow's location was too remote. Large-scale Ninja mobilization was simply unrealistic, not to mention having to pass through the territory of Kirigakure.
At most, it would only attract some elite Ninja assassinations. This kind of thing was just sending experimental subjects to him, so Vegapunk didn't care at all.
But for now, Vegapunk didn't have much demand for the Sharingan. Or rather, the value of the Kamui eye in Kakashi's eye socket was too great, and Vegapunk didn't want to start with it right away, so he hadn't made a move.
Not to mention that this eye also involved Uchiha Obito. It was fine while in Kakashi's eye socket, but if it were taken by someone else, this current mastermind would definitely not let it go. Vegapunk didn't want to face off against Uchiha Obito and Black and White Zetsu so early.
Skillfully tying several Kirigakure Ninjas to the experimental table, Kakashi Hatake was not some naive, hot-blooded rookie. Every hidden village had its dark side, and human experimentation was a common and ordinary occurrence.
Anyway, as long as he wasn't the one being experimented on, it was fine. Kakashi Hatake cast a pitying glance at the Kirigakure Ninjas. The ones who had come to scout the laboratory a while ago had been electrocuted to death during Vegapunk's lightning adaptability experiments. Their deaths were so gruesome that Kakashi, who later cleaned up the lab, didn't want to remember them.
Just as Kakashi was about to leave, he saw Vegapunk suddenly reach out: "Hey, Kakashi, wait a moment!"
Kakashi's body trembled slightly, his eyes looking at Vegapunk with some wariness. He saw Vegapunk take out a scroll unique to the Naruto World and hand it directly to Kakashi.
"This is the latest modified version I derived from the last lightning adaptability experiment and the secret technique I borrowed from you that uses lightning to stimulate cell activation. Use it for training during this period!"
Although Vegapunk looked nonchalant, Kakashi Hatake turned pale upon hearing those words: "Just... just developed? This effect..."
Lightning Release secret techniques that stimulate cell activity can be said to be the top-tier, most high-end Ninjutsu among Lightning Release techniques. Similarly, their danger is incredibly high.
Looking at those unlucky fellows who were electrocuted to death by Vegapunk, one could see the danger. One must know that for a scientist of Vegapunk's level, it had been a long time since someone died during his research in human experiments.
Moreover, Kakashi knew very well just how dangerous these kinds of Ninjutsu that use Lightning Release to stimulate cell activation were!
The top-tier Lightning Release secret technique for stimulating cell activation in the Naruto World is none other than Kumogakure's Lightning Release Armor. Behind the reputation that allows the Lightning Release Armor to rival the Flying Thunder God Technique and the Bloodline Removal Dust Release is a mountain of experimental subjects and the corpses of those who failed in their cultivation!
To some extent, the Lightning Release Armor is rated as a B-rank Ninjutsu precisely because Kumogakure invested so much effort into it. One must know that in the Naruto World, the rank of a Ninjutsu is judged not by its power, but by its difficulty.
In other words, the Lightning Release Armor has a minimum power level of A-rank and a maximum of S-rank, but its cultivation difficulty is only B-rank. Because if the difficulty were any higher, the danger would explode. To lower its cultivation difficulty to B-rank, God knows how many people Kumogakure sacrificed.
And now, this scientist, who had only recently obtained Chakra, had developed a so-called new version of the cell activation Ninjutsu after just getting a rough method for lightning cell stimulation from him and conducting a few human experiments. No matter how you looked at it, this seemed unreliable!
This kind of Ninjutsu is not something that can be easily cultivated. Kakashi absolutely did not want to see the consequences of an incorrect cultivation method.
Seeing Kakashi's deathly pale face, Vegapunk couldn't help but roll his eyes. A Ninjutsu he had personally deduced through the quantum brain and human data, yet this guy looked scared to death. He really didn't know what was good for him.
You should know that in the original One Piece World, the training pods Vegapunk casually manufactured sold for super high prices of several hundred million Berries on the black market!
Those training pods utilized a portion of vibration and electrical stimulation capabilities, allowing an ordinary person to reach the level of a pirate with a bounty of twenty or thirty million Berries within a year. At the same time, no arduous training was required; one only needed to rest in the training pod every day.
Of course, what Vegapunk sold were all entry-level versions. True top-tier training pods had to be custom-made according to an individual's physique and paired with extensive training plans, high-energy nutritional food, and recovery fluids to truly develop a person's potential to its limit.
