Developed Ninjutsu

"Just as expected, once the reputation spread, new experimental materials came knocking!"

Sitting in the Laboratory, Vegapunk smiled as he watched Kakashi Hatake drag in the experimental materials from the Water Country, sounding rather pleased.

Kakashi Hatake rolled his eyes but said nothing more. As a genius Ninja famed for being calm and clever, he had no desire to end up back on the operating table.

Vegapunk's arrival might have been a good thing for Snow Country, but it certainly was not for Kakashi. In terms of value, Kakashi was far more valuable than those Snow Ninjas.

Perhaps in terms of combat strength, the numerous Snow Ninjas, bolstered by their unique climate, held an absolute advantage against Kakashi. But when it came to potential and the knowledge stored in his mind, Kakashi surpassed those Snow Ninjas by an immeasurable margin.

Thus, Kakashi had initially become a regular on Vegapunk's operating table. Though Kakashi himself had been unwilling, faced with such an overwhelming gap in strength, he had wisely complied.

Vegapunk's Laboratory happened to be located in the crater of a Dormant Volcano. Drawing upon its endless geothermal energy, the Quantum Brain had been partially activated. Even that small fraction of its power possessed computational capabilities beyond human imagination. With the Quantum Brain, Vegapunk had already analyzed every Ninjutsu in Kakashi's mind.

Kakashi was not yet the Copy Ninja who possessed a thousand Ninjutsu, but he still had dozens, perhaps over a hundred, stored away. In one stroke, he had greatly enriched Vegapunk's Ninjutsu Database.

As for whether this would cause trouble or offend Konohagakure... given Snow Country's location and the strength of Vegapunk's group, Konohagakure could not possibly mobilize on a large scale and come all this way to fight for the Ninjutsu in Kakashi's head.

If Vegapunk had taken Kakashi's Sharingan, there might have been some trouble, but it still would not have sparked a war—Snow Country was simply too remote. Large-scale Ninja deployments were utterly impractical, especially when they would have to pass through the Water Country.

At most, they would send a few elite Ninjas to assassinate him. To Vegapunk, that was merely sending him more experimental subjects, so he did not care in the slightest.

However, Vegapunk had no need for the Sharingan at the moment. Or rather, the Kamui Eye in Kakashi's socket was simply too valuable, and Vegapunk did not want to start with it, which was why he had not made a move.

Not to mention that eye was connected to Obito Uchiha. It was fine while it remained in Kakashi's eye socket, but if someone else took it, the current mastermind behind the scenes certainly would not let it go. Vegapunk did not wish to clash with Obito Uchiha, Black Zetsu, and White Zetsu so early on.

Skillfully tying several Kirigakure Ninjas to the operating tables, Kakashi Hatake was no naïve, hot-blooded rookie. Every Ninja village had its dark side, and human experimentation was a common, utterly ordinary occurrence.

As long as he was not the one being experimented on, it was fine. With a mournful expression, Kakashi Hatake glanced at the Kirigakure Ninjas. The ones who had come to scout the Laboratory some time ago had been electrocuted alive during Vegapunk's Lightning Adaptation Experiment. Their deaths had been so gruesome that Kakashi, who had cleaned up the Laboratory afterward, did not even want to remember them.

Just as Kakashi was preparing to leave, Vegapunk suddenly held out a hand. "Hey, Kakashi, wait a moment!"

Kakashi's body trembled slightly as he looked at Vegapunk with wariness. Vegapunk took out a distinctive scroll from the Ninja World and handed it directly to him.

"This is the newest revised version I developed from the previous Lightning Adaptation Experiment and the secret technique you lent me for using lightning to stimulate cellular activation. Train with it for a while."

Although Vegapunk looked completely nonchalant, Kakashi Hatake's face went pale when he heard that. "Y-you just developed it? What about its effects...?"

Lightning Release Secret Techniques that stimulated cellular activity could be considered the most advanced and high-level of all Lightning Release Ninjutsu. Naturally, their danger was equally unimaginable.

Just looking at those unlucky men Vegapunk had electrocuted to death showed how dangerous it was. A Scientist of Vegapunk's caliber had not had anyone die during his research for a very long time.

Moreover, Kakashi understood very well just how dangerous Ninjutsu that used Lightning Release to stimulate cellular activation truly were!

The greatest Lightning Release Secret Technique in the Ninja World for stimulating and activating cells was Kumogakure's Lightning Armor. Yet behind Lightning Armor's reputation, rivaling that of the Flying Thunder God Technique and Dust Release Kekkei Tota, lay piles of experimental subjects and failed trainees' corpses as high as mountains!

To some extent, the reason Lightning Armor was rated as a B-rank Ninjutsu was precisely because Kumogakure had poured too much effort into it. After all, Ninjutsu rankings in the Ninja World were not determined by power, but by difficulty.

In other words, Lightning Release Armor was a Ninjutsu with an A-rank lower limit and an S-rank upper limit in power, yet only B-rank training difficulty—because if its difficulty rose any higher, its danger would explode. To reduce its training difficulty to B-rank, who knew how many people Kumogakure had sacrificed.

And now, this Scientist, who had acquired Chakra only recently, had supposedly developed a new version of a cell-activation Ninjutsu after obtaining his crude Lightning Release cell-stimulation method and conducting only a few human experiments. No matter how he looked at it, it seemed utterly unreliable!

This kind of Ninjutsu was not something one could train in so easily. Kakashi absolutely did not want to see the consequences of an incorrect training method.

Seeing Kakashi's deathly pale face, Vegapunk could not help rolling his eyes. He had personally derived this Ninjutsu through the Quantum Brain and human-body data, yet this guy still looked terrified out of his wits. What an ungrateful fellow.

Back in the original Pirate World, the Training Pods Vegapunk casually made sold for astronomical prices of several hundred million Berries on the black market!

Those Training Pods used a portion of vibration technology and electrical stimulation. Within a year, they could raise an ordinary person to the strength of a pirate with a bounty of twenty to thirty million Berries. At the same time, no grueling training was needed; one only had to rest in the Training Pod every day.

Of course, the ones Vegapunk sold were only entry-level versions. The true top-tier Training Pods had to be customized according to each individual's physique, supplemented with extensive training plans, high-energy nutritional food, and restorative fluid, before a person's potential could truly be developed to its limit.
