Tobirama Senju Joins, Iwagakure's Forbidden Technique Gift Pack

"Second Hokage, there's a saying that goes, 'The specific context defines what is morality. If you have the ability to define the context, ethics and morality are nothing more than clay in your hands, which you can manipulate at will.'"

Tobirama Senju frowned.

"Through the Limited Tsukuyomi, I can mass-produce Artificial Human. In this fictional world, I can adjust the flow of time. By simply consuming my eye power, I can make the flow of time in the Limited Tsukuyomi World dozens or even hundreds of times faster than in the real world."

"In this way, I can artificially shape the first twenty years of these Artificial Human ' lives. During these twenty years, they will undergo sixteen years of compulsory education, and in this process, I will select talents who are good at technology and those who are good at operations."

"At the same time, the personalities of these Artificial Human will also be molded into lawful good types."

"Once the first batch of Artificial Human have completed their development, I will use technological means to transplant their souls into real-world bodies."

Uchiha Jun's voice was calm, yet carried an undeniable confidence. "In this way, the problem of the post-war elite dying in large numbers, losing management, and causing chaos throughout the land... will naturally be solved."

"As for declaring war on the entire Shinobi World, I wouldn't be that foolish."

"With my strength and influence, I can easily carry out decapitation strikes in secret, hunting down high-ranking members of the old forces, including the Daimyo, in batches within a short period of time. After one round, I can directly declare Shinobi World and simultaneously dispatch Artificial Human troops to develop local areas around the world."

"At that time... I will be able to rightfully become the master of the new era!"

--

After Uchiha Jun finished speaking, a long silence fell over the laboratory.

Senju Hashirama and Tobirama Senju exchanged a glance.

The brothers' eyes held shock, scrutiny, and a hint of... complex emotions.

Tobirama Senju spoke first, his voice low and deep. "You mean... you want to create a completely new world?"

"No, no, no." Uchiha Jun shook his head. "I don't have that ability yet. What I mean is to correct this world. The systems of the Daimyo and the ninja villages are too outdated. Why don't we implement something more advanced?"

Senju Hashirama, who had remained silent throughout, paused for a moment before suddenly asking, "Why did you do this? Why did you bear this... responsibility?"

Although he observed for a period of time, Senju Hashirama still couldn't figure out Uchiha Jun's purpose, or rather, why Uchiha Jun chose to unify the entire Shinobi World.

Judging from his appearance, Uchiha Jun only sixteen or seventeen years old, and there was absolutely no need for him to shoulder this 'responsibility'.

What were he and Ban doing at that age?

... Let them fight all day long.

"... I won't hide anything, to be honest, I'm not satisfied with the current power of the Shinobi World, I want to explore the starry sky and obtain even greater power."

"And you all know how vast the starry sky is. If I were to go in alone, there's a more than 90% chance I'd die of old age rather than become stronger."

"Therefore, I plan to cultivate my own power and develop the entire Shinobi World into an interstellar force capable of roaming the stars. The prerequisite, of course, is to bring peace to the Shinobi World, so that everyone can live and work in peace and provide me with a large number of talented people."

"And this is my ultimate goal."

After Uchiha Jun revealed his ambitious and almost insane plans, the two brothers exchanged a glance.

Senju Hashirama, a long-lost fervor flickered in his eyes, which had been dormant for decades.

Tobirama Senju remained silent for a long time.

His gaze swept over Uchiha Jun's young face, as if assessing a dangerous experimental subject.

"I agree to cooperate with you."

Tobirama Senju finally spoke, his voice as cold as if he had been pulled from an ice cellar.

Uchiha Jun's lips immediately curled into a smile, and he enthusiastically opened his arms. "Welcome! Welcome the First and Second Hokage to the strongest research team in the Shinobi World!"

"Snort."

Tobirama Senju a cold laugh.

"Even if my brother and I disagree with your plan, you'll still resort to all sorts of underhanded tactics, won't you?"

Uchiha Jun was taken aback by what he heard.

Then he smiled.

His smile was as bright as Himawari in the sunlight, but the words that followed sent a chill Tobirama Senju's spine, even though he had already died once.

"The Second Hokage is truly intelligent; he guessed that all along."

"If you don't agree, I'll keep using the Impure World Reincarnation to pull you out of the Pure Land, send you back, pull you out again, and send you back again..."

Uchiha Jun paused, then added, "And after each Impure World Reincarnation, I'll forcibly dress your Reanimated Body in all sorts of humiliating outfits—and make it stroll around the most prosperous streets of Konoha."

"Let all the villagers of Konoha see how... graceful their Second Hokage's figure is."

As soon as he finished speaking, Orochimaru and the others beside him gradually turned red in the face, while Tobirama Senju's eyes suddenly widened.

For the first time, a crack appeared on that usually calm and collected face.

"You beast!!"

Tobirama Senju practically roared it out.

The Impure World Reincarnation was a forbidden technique he developed, and he understood its principles better than anyone else.

If the caster truly has this intention, then he/she is truly powerless to resist!

The thought of himself parading through the streets of Konoha in all sorts of shameful outfits made Tobirama Senju Senju's soul tremble.

"Hahaha..."

Senju Hashirama to the side, laughed so hard he slapped his thigh, "Tobirama, this kid's got some skills!"

"Shut up, brother!"

"Don't forget, you can't escape either!"

"Tobirama Senju roared."

Uchiha Jun watched this scene with satisfaction. After soothing Tobirama Senju's shattered pride, Uchiha Jun began to get down to business.

Biting your finger to Hand Seals with spirits.

"Summoning Technique!"

Thud--

A cloud of white mist dissipated, and the Mofang appeared on the deck of the Sky Fortress.

"Hey! Chun! What brings you here this time?"

The Mofang's Cube, now much larger than when they last met, raised its pink and tender paws and greeted Uchiha Jun.

"Mofang's Cube, you've gotten fatter again."

"... Give this letter to Kakuzu, and use this million to buy food."

After rubbing the Mofang's Cube's head, Uchiha Jun handed Mofang a letter and a scroll.

The letter contained very simple information: Uchiha Jun instructed Kakuzu to activate his intelligence network and search the entire Shinobi World for information on the burial sites of the past Kage of the Five Great Ninja Villages, as well as to purchase the remains of famous Shinobi World from the past.

"Thank you, Chun! I'll be going now!"

After accepting the letter and scroll, the Mofang rubbed against Uchiha Jun's palm before using the Reverse Summoning Technique to teleport away.

Just as Uchiha Jun was about to show Senju Hashirama and Tobirama Senju around his Sky Fortress and familiarize them with their future work environment...

Uchiha Jun sensed a fluctuation emanating from the Summoning Contract.

Raise your hand to Hand Seals.

--The Summoning Technique.

Thud--

A small, emerald-green snake emerged from the smoke, carrying a scroll in its mouth.

Uchiha Jun took the scroll, opened it, and his expression first froze slightly before revealing a meaningful smile.

"Interesting."

The person who sent the letter was the Artificial Human personality within Kitsuchi, a spy previously planted in the Iwagakure by Uchiha Jun through the Limited Tsukuyomi.

After this period of operation, ' Kitsuchi 2.0' has lived up to Uchiha Jun's expectations, successfully digging out all of Iwa-nin's secrets and sending them all sorts of secret techniques, forbidden techniques, Ninjutsu to Uchiha Jun.

Release the list from the scroll.

Uchiha Jun watched with great interest.

On the list, Ōnoki's signature Ninjutsu from the original work was prominently featured.

Earth Release: Golem Technique – Earth Release Secret Technique: Summons a gigantic rock giant with destructive power to crush everything.

The Light-Weight Rock Technique – altering the weight of objects, making them as light as a feather or as heavy as Mount Tai.

The Added-Weight Rock Technique greatly increases the weight and hardness of objects; a single punch can cause mountains to crumble and the earth to split.

Earth Mountain Technique - Summons two massive mountains to sandwich the enemy and grind them into dust. In the original work, even Kitsuchi can be used to elbow the Ten-Tails!

These are all the most closely guarded secret techniques of Iwagakure.

In addition to Earth Release Ninjutsu, related Ninjutsu of Kekkei Genkai such as Lava Release, Boil Release, and Explosion Release were also copied by "Kitsuchi 2.0".

But what truly surprised Uchiha Jun was another piece of information.

--In the original work, the Explosion Release technique used by Deidara was indeed not Kekkei Genkai.

Instead, it was obtained through a Explosion Release derivative called a "Detonation Core".

Uchiha Jun narrowed his eyes slightly.

Keep reading.

The letter contained extremely detailed records about the Detonation Core.

The Detonation Core is a product cultivated using the genes of ninjas with the Explosion Release Kekkei Genkai through special methods.

Its shape is a regular geometric shape of varying sizes—sometimes square, sometimes rectangular, sometimes round—looking like beautiful gemstones.

But its power is enough to terrify any ninja.

The Detonation Core grants the user abilities equivalent to the Explosion Release Kekkei Genkai Chakra, allowing ordinary ninjas to use Explosion Release chakra!

Upon seeing this, Uchiha Jun's lips curled into a slight smile.

"Interesting, very interesting."

Initially, the Detonation Core was used to break up rocks and clear nearly 70% of the land in Iwagakure.

The Detonation Core played a crucial role in enabling Iwagakure to establish a massive underground city in that barren, rocky region.

But later, the Detonation Core quickly disappeared.

The reason was not the opposition from the family with the Explosion Release Kekkei Genkai.

The real problem with Detonation Core lies in the nucleus itself.

This product, while incredibly powerful, is extremely unstable.

Once the core of the Detonation Core comes into contact with Chakra, it will rapidly condense and fission.

Not only will the user die instantly, but they will also drag all living things within a radius of at least ten kilometers down with them.

At first, the Tsuchikage didn't take it seriously, thinking it was an accident.

However, as time went on, the continuous stream of self-destruction incidents finally drew attention.

Subsequently, researchers in Iwagakure discovered that the Detonation Core gradually changes and its stability declines with the user's usage time and frequency.

Ultimately, for safety reasons, the Tsuchikage ordered a halt to the use of Detonation Core and disposed of all stockpiled Detonation Core in designated "minefield" areas.

Those areas have now become forbidden zones around Iwagakure, and no one is allowed to approach them.

Uchiha Jun put down the letter, a thoughtful glint in his eyes.

"Detonation Core... that's good stuff."

Senju Hashirama, listening from the side, was completely confused. "What's Detonation Core? Is it that powerful?"

Seeing this, Uchiha Jun casually spread the two Secret Scroll on the table, his movements as relaxed as if he were getting food in a cafeteria.

"Just these two things, take a look."

Tobirama Senju raised an eyebrow.

He picked up the scroll and instantly felt a chill run down his spine. He no longer took Uchiha Jun's boastful words lightly.

He'd lived all these years and seen arrogant people, but never anyone this arrogant.

Dust Release – Kekkei Tōta, surpassing Kekkei Genkai. It is a forbidden power that only the Second Tsuchikage Mu and the Third Tsuchikage Shinobi World Ōnoki ever mastered.

The Detonation Core —a genetic product of the Explosion Release Kekkei Genkai— was a dangerous item that once enabled the Iwagakure to clear land, but was also urgently sealed away due to a series of self-destruction incidents.

Either of these two items is a prized possession that the Iwa-nin would love to hide in their crotch.

As a result, in Uchiha Jun, they were just "two things" and he didn't take them seriously at all!

This kid's intelligence network is terrifyingly powerful!

"Chun-jun, your casualness... is truly enviable."

"As expected of you, you even managed to get your hands on such confidential information. Looks like we're in luck today."

Orochimaru stuck out his long tongue, licked his lips, and with a thirst for knowledge in his eyes, he was the first to pick up the Dust Release Secret Scroll.

"Let me see just how wonderful the legendary Kekkei Tōta system truly is..."

Orochimaru slowly unrolled the scroll.

His pupils gradually contracted, clearly shocked by what he saw.

"... Wind, Earth, and Fire, these three attributes are mixed in specific proportions. Earth forms the barrier and the material basis, Wind is responsible for intensifying the matter to a critical value, and Fire is responsible for providing energy and further intensification..."

Orochimaru's voice grew slower and softer.

In the end, Orochimaru put down the scroll of Dust Release, his expression showing some relief.

"Hey, really? You think your Dao Heart is shattered just from watching a Dust Release?"

"No way, bro. You're one of the Sannin, someone who's seen more forbidden techniques than I've seen anime. You're just stunned?"

"You don't understand." Orochimaru carefully placed the scroll down, as if it were some fragile treasure. "All along, Kekkei Genkai have been a product of talent, the result of the fusion of innate Chakra attributes, an unrepeatable consensus."

"This Dust Release training scroll is clearly something that can be learned later in life. Undoubtedly, the Second Tsuchikage Mu, who created this Kekkei Tōta technique from scratch, has a far greater mastery of Chakra nature than I have."

"Today's meeting truly reveals that there are always people more capable than oneself."

Upon hearing this, Hiruko, who had been silent all along, suddenly raised his head.

"Let me see." Hiruko grabbed the Dust Release Secret Scroll, his eyes blazing as he quickly scanned every line of text.

"Wonderful..." Hiruko, "This Chakra structure... Earth Release as the skeleton, Wind Release as the blade, Fire Release as the furnace... the three cycle and generate each other, intensifying each other..."

She suddenly looked up at Uchiha Jun:

"Boss, I want to research Kekkei Genkai, and even start a project to research Kekkei Tōta!!"

"Stop." Uchiha Jun Teuchi. "Hiruko- chan, don't just look at how strong Dust Release is. If it can't hit anyone, it's just useless. You haven't seen Ōnoki use Dust Release."

"I don't know if it's because he's not skilled enough, or it's a limitation of Dust Release itself, but the wind-up is longer than his lifespan. It's only really effective against live targets like Tailed Beasts."

"Is that so..."

Hiruko seemed to be deep in thought after Uchiha Jun's words. Originally, her desire for Kekkei Genkai had shifted to Kekkei Tōta, but Uchiha Jun's words dispelled that illusion.

It seems to be nothing special.

"Don't be discouraged. It's not that I don't want you to do research, but I want you to be well-prepared before you start. After all, my money didn't grow on trees; I earned it bit by bit."

"How about this, you go and work on the Kekkei Genkai and Kekkei Tōta synthesis project?"

"Really! Thank you, boss!!"

"It's nothing." Uchiha Jun waved his hand. "You should look at the one with the Detonation Core first."

"That thing is somewhat related to genes, and it has some similarities to your Chimera."

Hiruko put down the Dust Release Secret Scroll and picked up the Detonation Core Creation Secret Scroll.

She frowned after watching for only a short while.

"This... is interesting."

"How so?"

"The principle of the Detonation Core is essentially to use the genes of a ninja with the Explosion Release Kekkei Genkai as a 'seed,' and through Chakra, form a 'core' that can continuously produce Explosion Release Chakra."

Hiruko to the structural diagram on the scroll, "But the problem is that the stability of this core depends entirely on the cellular activity of the gene provider."

"The stronger the cell activity, the more stable the core?"

"Quite the opposite," Hiruko his head, "The stronger the cell activity, the less stable the core."

Uchiha Jun:???

"Because the essence of Explosion Release is 'detonation,' and the more active the cell, the higher its sensitivity to Chakra."

Hiruko, "Each time a user injects Chakra, it triggers a micro-fission reaction within the core. This fission is irreversible. When the damage within the core accumulates to a certain extent—"

"Boom!" Uchiha Jun chimed in.

"Yes, boom."

Hiruko, "And as you wrote on your scroll, the most terrifying thing is that once this core enters a critical state, its explosion radius will increase exponentially. A Detonation Core the size of a fist is enough to render everything within a ten-kilometer radius barren."

"Unless... unless the user possesses Explosion Release Chakra, or masters the ability to synthesize Explosion Release Chakra independently during the use of the Detonation Core, it is impossible to 'maintain' the Detonation Core and extend its lifespan."

Silence fell over the laboratory once again.

Uchiha Jun stroked his chin, pondered for a moment, and then turned to look at Tobirama Senju, who had been silent since earlier, quietly flipping through various Scroll of Seals.

"Second Hokage, what do you think?"

Tobirama Senju walked to the table, picked up the Secret Scroll containing the Detonation Core, his gaze calm, and after a moment offered his insight. "The problem with this Detonation Core is not that it is unstable, but that its 'stability threshold' is too low."

Uchiha Jun's eyes lit up. "There's a way?"

"A solution?" Tobirama Senju scoffed. "There are plenty of solutions."

"Look here, the production path of Explosion Release Chakra is one-way, from the core to the user, there is no return channel."

"This means that once the user's Chakra is injected, the energy balance inside the core will be disrupted, and it will be unable to repair itself."

"If it were here—" Tobirama Senju moved his fingers to the side of the structural diagram.

"Add a Chakra circuit so that the core can automatically balance its internal energy distribution when the user is not using Explosion Release Chakra..."

"That will extend the lifespan of the core?"

"It's not just about extending it." Tobirama Senju's lips curled up slightly, revealing a rare hint of smugness.

"If designed properly, the core could theoretically become a 'renewable' energy source. As long as the user doesn't extract more Chakra than the core can handle at once, it can repair itself and continue to be used."

"Of course, this is just theory," Tobirama Senju added. "In practice, it requires a lot of experimentation to verify and adjust, and—"

Are you sure you want to mass-produce this kind of thing?

"Absolutely," Uchiha Jun said matter-of-factly. "Equip them to my Back-Pounding Army, and everyone will be Kage Level fighter. Then we can unify the Shinobi World, achieve peace, and reach the pinnacle of life... Doesn't that make perfect sense?"

Tobirama Senju fell silent for a moment.

Looking at the young Uchiha Clan clansman before him, he suddenly felt somewhat dazed.

He recalled his youth, when he and his elder brother founded Konoha, hoping to end that era of war.

He developed forbidden techniques, researched Ninjutsu, and trained disciples, all for this goal.

But until his death, the Shinobi World never truly experienced peace.

"Evil brat," Tobirama Senju his breath.

"Thank you for the compliment." Uchiha Jun grinned.

I wasn't praising you.

"Then I'll take that as a compliment."

Tobirama Senju: "..."

Taking a deep breath, he decided not to stoop to Uchiha Jun and turned to look at the Dust Release Secret Scroll.

"... Does the fusion ratio of the three attributes need to be dynamically adjusted under different output intensities?"

"And the Chakra output ratio needs to be constantly adjusted during activation? No wonder even the Second Tsuchikage Mu, the founder of Dust Release, needed to use ' Perfect Invisibility ' to avoid the huge pre-cast animation of Dust Release."

"To maintain such a terrifying Ninjutsu, the energy and Chakra consumed must be enormous!"

Tobirama Senju read it several times, his brows furrowing deeper and deeper:

"Earth attribute 40%, Wind attribute 30%, Fire attribute 30%, this is the basic ratio, but if we want to expand the output range, the Fire attribute ratio needs to be increased to 40%, while compressing the Wind attribute output channel..."

"If the goal is high-density penetration, the proportion of wind attribute should be increased to 40%, fire attribute reduced to 20%, and earth attribute kept unchanged at 40%..."

Tobirama Senju put down the scroll and rubbed his temples.

"This technique is more complex than I imagined."

"What do you mean?" Uchiha Jun leaned closer.
