Arrival in the Land of Water, Pakura

Seimei hearing Uchiha Jun's question, Seimei quickly retrieved a new scroll from his chest cavity and unfolded it on the table—it was a three-dimensional structural diagram of a lunar base, with layers of lines and markings, more detailed and more awe-inspiring than the previous exploration maps.

"Boss, the preparations for the Lunar Dock have completed the first phase—site selection and preliminary infrastructure construction."

Seimei's fingertips traced across the scroll, pointing to a region on the lunar surface marked "Number 1":

"The dock is located inside a large crater on the near side of the moon. The crater's naturally formed depression, about 15 kilometers in diameter, saved us about 40 percent of the earthwork excavation."

"Currently, the White Zetsu Corps have completed the following tasks--"

"First, the foundation reinforcement at the base of the crater—support pillars cast from Chakra-Conducting Alloy Ore were driven 500 meters underground, forming 45 main support points. Each support point can withstand a vertical pressure of up to one million tons."

"Secondly, the excavation of the dock outline—the dock foundation pit, approximately 14 kilometers long, 4 kilometers wide, and 600 meters deep, has been excavated at the bottom of the crater. At the current pace, it is expected that all earthwork excavation and foundation pouring will be completed in another month."

"Third, supporting facilities—four smelters, two material processing plants, a Sealing Jutsu engraving workshop, and an underground living area that can accommodate 5,000 workers at the same time have been built on the outer perimeter of the crater."

"--In other words, the main structure of the dock itself is expected to be completed within three months."

A hint of approval flashed in Orochimaru's eyes. "--Your efficiency is indeed astonishing, but did you use the Ninjutsu of the Back-Pounding Army' to achieve this speed?"

Uchiha Jun has not launched a large-scale war yet. When he fought against the Moon Ōtsutsuki, he directly fought Ōtsutsuki Hamura in a 1v1. After killing Ōtsutsuki Hamura, the Ōtsutsuki Clan also slid to their knees at lightning speed, without needing to use the Back-Pounding Army.

However, even if it's not needed, it doesn't mean that the Back-Pounding Army is completely useless.

In Uchiha Jun and Orochimaru's design, the Back-Pounding Army" had reached the level of Jonin in terms of basic Ninjutsu skills in earth and wood construction, making them much more efficient at infrastructure construction than ordinary people.

"That's for sure. Those Artificial Human are extremely efficient. Without them, this shipyard probably wouldn't have been built so quickly." Seimei smiled slightly, but quickly added.

"However, the shipyard is only the first step. The real difficulty lies in building that 10,000-meter-class Sky Fortress —the giant ship in Plan One—within the shipyard. Whether it's the design of the propulsion system, the arrangement of the spell array, or the industrial-scale production of Chakra Crystal Alloy, these are all unprecedented challenges."

"I'll handle the powertrain problem."

Uchiha Jun's voice. "The power requirements of five Moryo - Zero-Tails Demon Refineries are indeed considerable, but I already have a preliminary alternative plan. If it can be implemented, it will be more than enough to power a mere 10,000-meter-class interstellar warship!"

Tobirama Senju his arms crossed, leaning back in his chair, his brow furrowed.

His gaze lingered on Uchiha Jun's face for a moment, then he spoke slowly, his voice carrying a hint of scrutiny:

"You bastard, you just said you already have an alternative?"

"--Moreover, it's enough to meet the energy consumption of a 10,000-meter-class interstellar warship?"

"While my understanding of modern Ninjutsu technology may not be as profound as Orochimaru's and Seimei's, I do understand the basic concept of 'energy.'"

"A warship with a length of 10,000 meters—just maintaining its basic cruising requires the equivalent of five Moryo Zero-Tails Power Reactors."

"If we add the Amaterasu Turret Array, the Tsukuyomi Illusion Barrier, and various auxiliary systems you mentioned—the peak energy consumption of that warship would probably be several times higher."

"What do you plan to use to fill this level of energy gap?"

"Only if you capture all Nine Tailed Beasts and use them as power sources could you sustain this, right?"

Uchiha Jun's lips curled up, and he spoke calmly.

"What if I told you that the power source I designed is more stable than the Tailed Beasts, more controllable than the Tailed Beasts, and—theoretically—it can multiply indefinitely?"

Tobirama Senju's brow furrowed even deeper. "What do you mean?"

Uchiha Jun did not answer directly, but instead turned to Orochimaru:

"Orochimaru, do you still remember the 'characteristics' of the Impure World Reincarnation?"

Orochimaru was slightly taken aback, then a knowing glint flashed in his eyes:

"You mean... the Reanimated Body possesses the characteristic of 'infinite Chakra '?"

"That's right."

Uchiha Jun nodded. "The Impure World Reincarnation Jutsu summons the souls of the dead from the Pure Land, attaches them to sacrificial offerings, and brings them back to life."

"One of the most distinctive characteristics of the Reanimated Body is that they possess almost unlimited Chakra."

"In other words, as long as the technique itself doesn't collapse, the Reanimated Body can—generate Chakra infinitely and continuously."

Tobirama Senju's expression changed in that instant.

As the developer of the Impure World Reincarnation Jutsu, he knew better than anyone else that Uchiha Jun was right.

The Reanimated Body does indeed possess nearly unlimited Chakra.

But when he developed this technique, he never imagined that someone would use this characteristic for this purpose.

"--you mean..."

Tobirama Senju's voice carried a hint of disbelief:

"You want to use the Reanimated Body as the power source for the warships?"

To be precise --

Uchiha Jun extended his finger and slowly drew a circle in the air:

"I want to build a ' Impure World Engine '."

"A large number of Reanimated Body continuously generate Chakra within a specially designed container. Then, through a jutsu array, their Chakra is extracted and gathered into a massive, inexhaustible energy stream—supplying the entire warship."

"In theory, as long as there are enough Reanimated Body of sufficient quality, the total amount of Chakra generated can be infinitely accumulated."

"The power output of five Zero-Tails reactors? That's just the beginning."

"At that time, fifty, five hundred, or even five thousand—as long as the number of Reanimated Body can keep up, the power can be stacked infinitely!"

The conference room was deathly silent.

Orochimaru's snake-like eyes narrowed slightly, and his breathing became somewhat rapid. He understood the profound meaning behind Uchiha Jun's plan, as well as the almost limitless possibilities it contained.

"... interesting."

Orochimaru licked his lips, his voice tinged with barely suppressed excitement:

"The Reanimated Body does indeed possess the characteristic of unlimited Chakra, but the problem is that Impure World Reincarnation requires sacrifices."

"Each Reanimated Body requires a living person as a sacrifice, and the quality of the sacrifice directly affects the strength and Chakra production efficiency of the Reanimated Body."

"Lord Chun, where do you plan to get so many high-quality offerings?"

Uchiha Jun, a smile carrying a chilling undertone.

"This is the second key point I'm going to make next."

"We need to 'make' offerings."

"Manufacture?"

"--Using gene editing technology, batches of ' Artificial Human ' with high-purity Uzumaki Clan bloodline have been cultivated. After special cultivation, the Chakra within these Artificial Human can easily reach the level of Tailed Beasts."

Tobirama Senju his brow:

"Artificial Human... Are you sure this kind of thing can be used as a sacrifice for the Impure World Reincarnation?"

"The sacrifice required for the Impure World Reincarnation is a complete person with a soul."

Uchiha Jun nodded, continuing Tobirama Senju's words:

"This is just part of my plan."

"The first step—using gene editing technology to mass-produce Artificial Human —as sacrifices."

"The second step—to implant the souls of criminals into these Artificial Human through Large Mangekyo Tsukuyomi —making these Artificial Human 'vessels with souls'."

"The third step—using these ' Artificial Human with souls' as sacrifices, activate the Impure World Reincarnation — Impure World Reincarnation the previous generation of ' Uzumaki Artificial Human,' thus enabling the cycle to continue."

"--This is--' Impure World Engine '."

"An endless energy system consisting of ' Artificial Human sacrifices + Reanimated Body + Chakra extraction containers'."

Tobirama Senju fell silent.

He once thought that his understanding of the Impure World Reincarnation was deep enough.

He once thought that the greatest taboo of Impure World Reincarnation was toying with the souls of the dead.

But now he realizes he was wrong.

Uchiha Jun's plan was not only to manipulate the souls of the dead—he was also manipulating the souls of the living, creating artificial life, and combining all of this into an industrialized, assembly-line-style energy production system.

This is outrageous! If things continue like this, won't his title as the Second Hokage be tarnished for eternity?

"... When I developed the Impure World Reincarnation Jutsu, I never imagined it would be used to this extent."

Tobirama Senju spoke slowly, his voice carrying an unprecedented sense of helplessness. "The Impure World Reincarnation is the most dangerous forbidden technique I have ever developed in my life."

"I once thought that its greatest sin was disturbing the peace of the dead."

"But now, you've told me about this wicked plan, and I'm afraid I'll become a notorious sinner for all time."

Upon hearing this, Uchiha Jun smiled and responded.

"Second Hokage, history is always written by the victors. Besides, even if people knew about this 'national treasure' that benefits the country and its people, what would they say?"

Tobirama Senju's lips twitched, and he opened his mouth, only to find that he couldn't find any words to refute it.

"... You scoundrel, I can't out-argue you."

Uchiha Jun smiled slightly, about to reply--

Just then, Seimei suddenly raised his head, a sharp glint flashing in his mechanical eyes.

"--Boss, please wait a moment."

Seimei quickly took out a crystal ball from his bosom and gently scratched its surface.

The mirror lit up, displaying a real-time transmitted image—an Sky Fortress's perspective overlooking a vast, undulating canyon landscape shrouded in thick fog beneath the clouds.

"--The Sky Fortress has arrived above the border of the Land of Water."

Seimei -headed fingers slid rapidly across the mirror surface, bringing up a set of data from a perception technique:

"According to the planned flight path, we are now directly above the ' Blood Mist Canyon,' which forms the northwestern border of the Land of Water."

"--At the same time, the detection radar detected an anomaly."

"A large amount of Chakra activity was detected in the canyon below."

"The number is approximately over one hundred."

"They are all members of the Kirigakure's Anbu, well-equipped, and on high alert."

Orochimaru narrowed his snake- Anbu eyes slightly. "--Hundreds of Kirigakure have gathered in Blood Mist Canyon? They're planning to ambush Elite Jonin- level ninjas."

Sasori spoke up, "--Has Kirigakure made any big moves recently? I remember that since the Third Mizukage took office, Kirigakure has always maintained a closed policy towards the outside world and rarely mobilizes such a large-scale Anbu force."

"The last time it appeared was during the Third Shinobi World War."

"What exactly is that old guy trying to do?"

Uchiha Jun did not answer immediately.

Uchiha Jun stood still, his gaze fixed on the communication mirror in Seimei's hand, looking thoughtfully at the canyon shrouded in thick fog reflected in the mirror.

After a moment, he slowly spoke:

" --Seimei, can you detect any other Chakra reactions outside the canyon besides those from the Kirigakure Anbu?"

Seimei quickly operated the communication mirror, and a moment later, he looked up, a hint of surprise flashing in his eyes:

"There really is."

"There's a Chakra reaction at the outermost edge of the canyon, moving towards the Mist Ninja's encirclement."

"Judging from the Chakra fluctuations, he should be a Kekkei Genkai ninja, and it seems to be a characteristic of ' Scorch Release '."

--Scorch Release.

--The Land of Water, Blood Mist Canyon, is surrounded by the Kirigakure Anbu.

A name instantly flashed into Uchiha Jun's mind.

--Pakura.

In the original story, he was betrayed by the Fourth Kazekage Rasa, Rasa, and ambushed by the Kirigakure Anbu —he suffered the same death as Neji Hyuga, being impaled by countless Kunai and Senbon, turning into a hedgehog.

"... I see."

Uchiha Jun murmured to himself.

"Seimei, order the Sky Fortress to maintain air superiority in place and remain concealed."

"Do not alert Anbu Kirigakure below."

Seimei was slightly taken aback. "Boss, what are you planning to do?"

"I plan to go down there."

Before he could finish speaking, Uchiha Jun had already disappeared from the conference room.

Outside the Sky Fortress, Uchiha Jun rapidly falling downwards, during his descent...

Sage Transformation--!

The next moment, a completely different aura erupted from his body.

A thin layer of Senjutsu Chakra- like luster, like flowing molten gold, appeared on the surface of the skin.

No teleportation capsule or landing device is needed.

In his current Sage Transformation state, falling from a height of ten thousand meters would only take him a few seconds.

The wind whistled past my ears.

Uchiha Jun's Sage Transformation Mode enhanced his body to the point where he could withstand a supersonic fall.

At the same time, Uchiha Jun's eyes maintained a clear field of vision even as he fell at high speed—the outline of the canyon below magnified and magnified in his vision.

He saw it.

On the outskirts of the canyon, three figures are slowly making their way along a winding mountain path.

Two men and one woman.

Among them, the two male ninjas leading the way wore Mist Ninja masks and were responsible for guiding the female ninjas behind them towards the Mist Ninja's encirclement.

The female ninja had long, dark green hair with orange-yellow tips at the temples.

He was wearing a standard ninja outfit.

--Pakura.

Uchiha Jun locked onto her location, adjusted his posture in mid-air, and ensured that his descent trajectory ended above the group, then blended into the environment using Senjutsu Chakra.

Its concealment is so great that even a sensory ninja cannot detect it.

It's worth mentioning that this technique was learned by Uchiha Jun from the secret teachings of Iwagakure, and it originated from the Second Tsuchikage Mu's secret technique, Dustless Bewildering Cover.

However, compared to the "Mude Dustless Bewildering Cover, Uchiha Jun's move was even more concealed.

Uchiha Jun did not choose to show himself immediately.

After all, from Pakura's perspective, he was here to negotiate with Kirigakure on a mission from the Sunagakure's higher-ups.

He wanted to see how this play would unfold.

Pakura stopped near the canyon entrance.

She looked up at the increasingly narrow mountain path ahead, and the towering rock walls on both sides that almost blocked out the sky, and a sense of unease welled up in her heart.

Her extensive combat experience told her that if there were ambushes above the canyon, she would surely die!

Pakura frowned.

As a ninja from Sunagakure, her mission this time is to represent Sunagakure in secret negotiations with Kirigakure —to discuss an agreement between the two countries.

"--How much further?"

Pakura asked, his voice slightly hoarse.

"--It's just ahead. Once you cross this canyon, you'll arrive. Lord Mizukage is waiting for you."

The operative Anbu the way spoke without turning his head, his voice calm and utterly emotionless.

Pakura didn't say anything more, but just silently followed behind him.

We walked for about five more minutes.

The canyon ahead suddenly opened up—it was a closed space surrounded by steep rock walls on all sides, like a natural fortress.

The Anbu leading the way suddenly stopped the moment they stepped into the open area.

"--arrive."

The sounds from the Anbu remained calm.

But in that instant, Pakura felt a bone-chilling cold.

She abruptly raised her head, looking at the retreating figure of the Anbu—

Under her gaze, the Anbu slowly formed a hand seal.

The next moment--

"Bang--!"

After a puff of white smoke, the Anbu had led the way had vanished from the spot.

Instead, hundreds of Kirigakure Anbu appeared instantly from all directions.

They stood on the rock walls on both sides of the canyon, looking down and completely surrounding Pakura.

In each person's hand, there was a Kunai or Senbon that gleamed with a cold light.

In everyone's eyes was a cold, predatory gaze.

Pakura's pupils contracted sharply.

The next moment, all that awaited her was --

The Anbu Captain standing at the highest point coldly swung his arm down:

"--put."

The next moment--

The sky Kunai, pouring down like a torrential downpour!

Hundreds of Kunai and Senbon kunai, gleaming with a deadly cold light, blocked all of Pakura's possible escape routes from all directions and angles!

The traces of those Kunai seemed to weave together at the same time into an impenetrable web of death.

Pakura's eyes widened in that instant.

She could only watch Kunai grew larger and larger in her vision—

Then, it stopped.

--

"Buzz--!"

A deep, resonant sound, like the tolling of a giant bell, echoed through the canyon.

Before Pakura appeared a huge, translucent skeleton radiating a pale purple light.

The skeleton rose instantly from the ground around her, completely enveloping her.

Hundreds of Kunai and Senbon struck the golden skull, producing a dense, metallic clanging sound—then they were all deflected and scattered on the ground.

"... What?"

Pakura was stunned.

The next moment, Pakura raised his head and looked upwards--

Then they saw a memorable figure standing quietly above everyone's heads.

Black hair, black eyes, and a calm, composed expression on his young face, as if he had everything under control.

"It's you?!"

Pakura's voice trembled slightly. She had never imagined that in this desperate situation, it would be Uchiha Jun had once drawn several vials of her blood, who would save her.

Uchiha Jun glanced down at her, a slight smile playing on his lips, "Long time no see, Suna-nin Hero?"

Upon hearing this, Pakura felt somewhat ashamed and indignant. Given her current situation, combined with the rumors circulating among the village's higher-ups not long ago, she already had some guesses.

"I didn't save you for nothing. Let me be frank, I'm planning to recruit you as my subordinate."

Having said that, Uchiha Jun's gaze swept over the Kirigakure Anbu members on both sides of the canyon. His voice was calm, yet carried an undeniable air of authority:

"Before that, let's clear out the weaklings first, and test my latest achievement."

As soon as he finished speaking, Uchiha Jun raised his right hand and waved it lightly.

The next moment--

"Bang--!"

"Bang--!"

"Bang--!"

Puffs of white smoke exploded one after another on the rock walls on both sides of the canyon!

From each puff of white smoke emerged a figure—

The figures were muscular, with skin that had a gray, rock-like texture.

Their eyes were empty, pure white, devoid of any emotion.

They were dressed in uniform, full-body gray-white armor, the surface of which was covered with densely packed Sealing Jutsu.

--The Back-Pounding Army.

3.0!

In just a few breaths, the rock walls on both sides of the canyon were filled with a full 150 Back-Pounding Army.

From their elevated position, they formed a commanding view, together with those Kirigakure and Anbu—

Standoff.

The captain of the Kirigakure Anbu's expression changed instantly.

He had never seen this type of enemy before—not ninjas, not puppets, but a kind of...humanoid weapons lined up in neat rows like soldiers, which he could not comprehend at all.

"... Who exactly are you?!"

The Anbu Captain's voice carried a hint of barely suppressed shock and anger.

"It's him! It's Uchiha Jun!!"
