Developed Ninjutsu

"Sure enough, having a reputation out there is great. Look, fresh experimental material has come knocking again!"

Sitting in the Laboratory, Vegapunk smiled as he watched Kakashi Hatake drag in the experimental materials from the Water Country, clearly delighted.

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

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

Perhaps in combat strength, the numerous Snow Ninjas, bolstered by their unique climate, held an absolute advantage over Kakashi. But in terms of potential and the sheer amount of knowledge in his mind, Kakashi surpassed those Snow Ninjas by countless times.

That was why Kakashi had initially become a frequent visitor to Vegapunk's operating table. Though Kakashi himself was unwilling, faced with such an overwhelming gap in strength, he knew better than to resist.

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

The current Kakashi was not yet the Copy Ninja who possessed a thousand techniques, but he had still stored dozens, perhaps hundreds, of ninjutsu. In one stroke, he had greatly enriched Vegapunk's Ninjutsu Database.

As for whether doing this would cause trouble or offend Konohagakure... given the Snow Country's location and the strength of Vegapunk's group, Konohagakure would never make such a massive move, crossing all that distance to fight to the death over the ninjutsu in Kakashi's head.

If Vegapunk had taken Kakashi's Sharingan, there might have been some trouble. But it still would not provoke a war—the Snow Country was simply too remote. A large-scale ninja deployment was utterly unrealistic, especially when they would have to pass through the Water Country.

At most, it would attract a few elite ninja assassins. To Vegapunk, that just meant more experimental specimens delivered to his door, so he did not care in the slightest.

Besides, Vegapunk had no need for the Sharingan yet. Or rather, the Kamui Eye in Kakashi's socket was simply too valuable. Vegapunk did not want to touch it right away, which was why he had not acted.

Not to mention that eye was tied to Obito Uchiha. It was safe enough in Kakashi's eye socket, but if someone else took it, the current mastermind behind the scenes would certainly not let the matter rest. Vegapunk did not want to face Obito Uchiha and Black and White Zetsu so soon.

Skillfully tying several Kirigakure ninjas onto the operating tables, Kakashi Hatake showed that he was no naive, hot-blooded fool. Every ninja village had its dark side, and human experimentation was an utterly commonplace affair.

As long as he was not the experiment, it was fine. Kakashi Hatake gave the Kirigakure ninjas a pitying look. Those who had come to spy on the Laboratory some time ago had been electrocuted to death in Vegapunk's Lightning Adaptation Experiment. Their deaths had been so miserable that Kakashi, who later cleaned the Laboratory, did not even want to remember them.

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

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

"This is the latest revised version I developed from the previous Lightning Adaptation Experiment and the Secret Technique you lent me for stimulating cellular activity with lightning. Train with it for a while."

Though Vegapunk looked utterly casual, Kakashi Hatake's face went pale at those words. "You... you just developed it? The effects..."

A Lightning Release Secret Technique that stimulated cellular activity could be considered one of the most advanced and sophisticated Lightning Release ninjutsu. Naturally, its dangers were equally unimaginable.

One only needed to look at those unlucky people Vegapunk had electrocuted to death to understand the danger. A scientist of Vegapunk's caliber had not had anyone die during research experiments in a very long time.

What was more, Kakashi knew very well just how dangerous ninjutsu that used Lightning Release to stimulate cellular activation could be!

The Ninja World's most advanced Lightning Release Secret Technique for stimulating and activating cells was Kumogakure's Lightning Armor. Behind Lightning Armor's reputation, comparable to the Flying Thunder God Technique and Dust Release Kekkei Tota, lay corpses piled as high as mountains—experimental subjects and failed trainees alike!

To some extent, Lightning Armor being rated as B-Rank ninjutsu was precisely because Kumogakure had poured too much effort into it. In the Ninja World, ninjutsu ranks were not judged by power, but by difficulty.

In other words, Lightning Release Armor was a technique with A-Rank power at minimum and S-Rank power at maximum, yet its training difficulty was only B-Rank—because if its difficulty rose any higher, its danger would increase explosively. To lower its training difficulty to B-Rank, who knew how many people Kumogakure had sacrificed?

And now, this scientist, who had only acquired Chakra not long ago, had developed a so-called new version of cellular activation ninjutsu after merely obtaining his crude Lightning Release cell-stimulation method and conducting a few human experiments. No matter how he looked at it, this seemed completely unreliable!

This was not the kind of ninjutsu that could be trained so easily. Kakashi absolutely did not want to see the consequences caused by an incorrect training method.

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

Back in the original Pirate World, the Training Pods Vegapunk casually created had sold on the black market for sky-high prices of several hundred million Beli!

Those Training Pods utilized part of the power of vibration 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. At the same time, they required no grueling training at all; one only had to rest in the Training Pod every day.

Of course, the versions Vegapunk sold were all basic models. The truly top-tier Training Pods had to be customized according to each person's physique, then supplemented with extensive training plans, high-energy nutritional food, and restorative fluid in order to truly push a person's potential to its limit.
