The founding of Konoha and the rise of the title of First Hokage had undoubtedly brought unimaginable changes to the ninja world.
The first to act was the Land of Lightning, located northeast of the Land of Fire.
In the Land of Lightning, the Lightning Release ninja “A” received full support from the daimyo of the Land of Lightning and gathered more than half of the ninja clans of the Land of Lightning to establish a ninja village called “Kumogakure.”
Subsequently, the Land of Earth, Land of Water, and Land of Wind each demonstrated what it meant to act as a great power in the ninja world.
The names of the three ninja villages — Iwagakure, Kirigakure, and Sunagakure — gradually took root, and village construction progressed at an astonishing speed.
The ninja clans that had been fighting in these countries instinctively gathered and, under the great pressure from the Land of Fire and Konohagakure, had no choice but to form alliances.
Although it was forced, if they could successfully unite, there would be more opportunities and time to hone their techniques, continuing until they truly became members of a ninja village.
Faced with the actions of the great powers, the small nations were completely confused.
They had neither the great foundation of the great nations nor powerful ninjas who could resolve problems in one blow.
Every clan refused to yield to each other and instead fought among themselves.
Some ninjas, seeing the system model of the Night Kingdom, thought that ninjas could also become daimyos.
Becoming the village head of a ninja village was wonderful, but becoming the ruler of a country was even more limitless.
A thought suddenly occurred to them.
“If he can become a Shogun, then so can I.”
Thus, a small daimyo near the Land of Lightning was killed, and the head of a clan proclaimed himself Shogun and seized power.
As a result, due to excessive brutality, political chaos, and constant changes in command, a nationwide rebellion broke out.
The clan head who called himself Shogun was killed, and the entire country became a blank slate.
Bandits, nobles, ninjas, samurai — people from all walks of life gathered here, chaos spread, and the economic and political ecosystem was completely destroyed.
In the end, even the daimyo of the Land of Lightning could not bear it, felt that the people of this small country were suffering too much, and tearfully annexed it.
As Yayoi had predicted, the great powers maintained the status quo and systematically organized the new order.
The small nations fell into chaos, unimaginable wild activities unfolded, and humanoid stars were witnessed shining brightly.
While watching this program together with the great powers, the Night Kingdom continued to develop steadily amid the turbulence of the era.
Some exiled ninjas and samurai broke through the borders of the Night Kingdom, but before they could cause chaos, Yayoi quickly dispatched units of ninjas and samurai to suppress them immediately.
The attacker was Kakuzu, and during this operation, he also obtained the heart of a Water Release ninja and incorporated it as a trophy into the forbidden technique “Earth Grudge Fear.”
There had also been a group of exiled ninjas from overseas before, but they were relatively honest and had truly come to escape disaster.
Through Kurobe’s mediation, these more than one hundred ninjas successfully joined the Night Kingdom.
There were no Bloodline Limit ninjas, but there were remnants of secret ninja clans, which brought Yayoi many surprises.
In the military system of the Night Kingdom, the number of ninjas had already exceeded one thousand.
Furthermore, the Education Department would soon begin operations, and the capable children of the Night Kingdom would soon become the new blood of the Night Kingdom and be injected into the national system.
Yayoi believed that in the next ten years, the official number of ninjas in the Night Kingdom would increase to at least 4,000.
Of course, the assimilation of samurai was also progressing.
Although the average strength of samurai was not as great as that of ninjas, they were still a powerful force and were considered one of the cornerstones of the Night Kingdom’s defense.
Yayoi attached great importance to this.
But now, training ninjas was the top priority.
After all, in modern times, ninjas were the mainstream, and samurai, monks, and shrine maidens would inevitably decline.
…
Heavy snow covered the magnificent and grand Yomi Castle.
Numerous geothermal systems installed underground released scorching steam, bringing spring-like warmth to this harsh winter day.
On the neatly maintained roads, figures that had never been seen before appeared.
They were armed groups dressed in white standard combat uniforms, wielding swords and knives.
The tight combat uniforms were uniformly engraved with red spider lily patterns.
Following the planned route, they took turns patrolling every street and corner of Yomi Castle, conducting uninterrupted patrols 24 hours a day.
They had a common name — members of the Security Force.
The Security Force was the newest public security management unit established in the Night Kingdom.
On the main road east of the Shogun’s residence, there was the headquarters building of this newly established department.
It was a six-story building with a large plaza, and a vast area of land had been allocated to this department, where a logistics and training base that was not open to the public was being constructed.
The members of this department were ninjas and samurai selected from the military, but they did not undertake national defense duties unless absolutely necessary and were responsible for handling domestic security and internal political disputes.
Due to a shortage of personnel, Yayoi decided to first conduct a one-year pilot project in the capital, Yomi Castle.
If the results were good, it could be expanded nationwide in the future once sufficient personnel were available.
In addition to the newly established garrison unit, several existing departments had also been reorganized with more detailed adjustments to improve operational efficiency.
Furthermore, to avoid functional conflicts in overlapping departments, Yayoi needed to gradually draw clear boundaries.
Otherwise, as time passed, it would easily cause conflicts between both departments.
By early March, a series of recent cases had been properly organized.
Since a month ago, Yayoi had gradually set aside his busy official duties and begun training in the private training ground in the inner courtyard.
The training ground in the inner courtyard was a large training area approximately 500 meters in length and width, located behind the main residence.
There were many simulation training devices here.
Special teaching materials made specifically for the venue were prepared to make actual combat easier.
Furthermore, trees were planted, rocks for obstacles were placed, a pond was dug to store water, and the training environment was made even more complex.
Within the inner courtyard, this training ground occupied one-third of the premises, showing the great effort Yayoi had put into it.
In the past, after finishing official duties, he would come here to train and hone his abilities.
In other words, the latter half of the previous year had been particularly busy, and from the latter half onward, his monthly training time had suddenly decreased.
At this moment, Yayoi stood on the gravel ground in the center of the training ground, taking a deep breath.
A beast-like aura was being released in all directions.
Visible blue flows swirled and gushed out like vortices — this was the materialized chakra created after the eruption.
His black hair was also unnaturally floating upward in the flow of chakra.
The materialized chakra became heavy and solid, turning into a substance that flowed like a stream of water, firmly binding to Yayoi’s sturdy body.
“Hmph!”
Yayoi let out a heavy groan, and suddenly a heavy force pressed down on her.
This pressure affected not only her body but also her bones and flesh, causing a stinging pain and a feeling of oppression.
After a few seconds of adjustment, the rough and chaotic aura around her gradually calmed down.
The physical chakra she released solidified into a layer of chakra armor like flowing blue flames, spewing tongues of flame over Yayoi like clouds or mist.
Without hesitation, Yayoi donned this layer of chakra armor, leaped forward, and at the same time jumped up like a rabbit.
His figure flickered on the spot, leaving a blue afterimage.
A blue flash cut through the air, and in an instant, he leaped dozens of meters ahead and threw a punch.
BOOM!
A hard rock several meters high instantly exploded, and countless fragments smaller than a fist scattered in all directions.
A shocking crater appeared at the explosion site.
It was the scar that appeared at the moment when the earth could no longer withstand the impact after the rock had been shattered and exploded.
Next, Yayoi approached a giant rock, hugged it with both hands, and easily lifted a stone weighing more than 10 tons.
The sight was like a child swinging a large sword the size of an adult.
THUD!
Upon reaching a certain height, the rock’s speed accelerated into the sky, as if touching the peak of its ascent.
The rock suddenly fell, accelerating while forming a thin air membrane, breaking through the atmospheric barrier.
Yayoi looked up from directly below and suddenly faced the falling rock without avoiding it, calculating time and distance in his mind.
Suddenly, he slightly bent his knees, the ground cracked, spiderweb-like fissures appeared, and using the earth as a stepping stone, he pushed with his feet, propelling his body into the air and launching himself like a cannonball.
BOOM!
The falling rock shattered into countless fragments just like the previous one, kicking up thick smoke and dust.
It was not a technique.
Yayoi had simply used his body to shatter the falling rock, carrying terrifying weight and force, and exploded it.
Landing on the ground, Yayoi descended from the sky like a soft feather, without the force to crush the ground beneath his feet.
One minute later, in the center of the training ground, which was hundreds of meters in both length and width, not a single thing remained unharmed.
It was as if it had been attacked by a giant beast, riddled with holes, tall trees uprooted by the blast, and the giant rocks remaining on the ground severely damaged without exception.
Parts of the ground were tilted, and cracks extended dozens of meters away.
It was as if someone had forcibly destroyed the essence of the earth using a powerful and advanced Earth Release ninjutsu, slicing it into uneven fragments of various sizes.
However, this was not caused by ninjutsu, but by taijutsu that brought destruction.
Furthermore, this was also the result of Yayoi’s self-restraint.
On a relatively unharmed patch of ground about half a meter above the surface, Yayoi’s body was enveloped in swirling blue fireworks like mist.
It looked as if flames were burning on her body, but there was no change in Fire Release techniques or the nature of chakra.
It was simply extremely concentrated physical chakra that unnaturally leaked out, creating a form that burned like flames.
This layer of chakra armor itself had no burning power and did not possess the temperature expected of flames.
“It’s almost stable.
The explosion speed is faster than the speed of sound.
After charging, both speed and destructive power can be increased further.
The loss of chakra is bearable, but the muscles still hurt a little.
It seems I need to train my body more…”
Yayoi quietly assessed his own condition.
The technique of maintaining the current state was a concept he had possessed since he first encountered chakra knowledge.
However, completing this technique had been extremely difficult, and he had only recently been able to turn it from imagination into reality.
With each strike, he could release the destructive power of ninjutsu, and his defensive power was also quite impressive — at the very least, ordinary destructive ninjutsu could be completely ignored.
For example, in this state, he could completely ignore this technique and disperse it with his fist.
Items such as kunai and shuriken could be used without chakra that caused nature transformation.
No matter how many were gathered, his defense would not be broken.
” Kichou, can you inject chakra into a ninja tool and slash at me with that?”
Yayoi looked toward the edge of the training ground.
His wife Kichou, dressed in a light purple and white kimono, had appeared there at some point.
“Oh my, does my husband have some special abusive fetish?
Because my husband said so…”
The girl teased with a smile, but her hands moved quickly.
She walked over to a nearby weapon rack and picked up a ninja sword.
Solid chakra easily enveloped the thin, blade-like weapon.
The quality of this ninja sword was superior to standard ones, with 30% chakra metal injected into it.
Ordinary ninja swords contained less than 10% chakra metal.
That was why, once chakra was bestowed upon it, its sharpness became extremely terrifying.
Ordinary ninja tools would likely crack after several contacts.
“I’m coming in now, husband.”
As soon as she finished speaking, Kichou flew toward Yayoi at an unbelievable speed, like a dancing butterfly.
The chakra-infused ninja sword had its sharpness pushed to the limit of the weapon.
She swung it down hard at Yayoi’s chest.
Naturally, even the chakra-infused ninja sword could not cut through Yayoi’s chakra armor.
Kichou stepped back several steps from the recoil of the blade.
“Wow, this defensive power is really…”
Kichou slightly opened her small mouth, and her pure white pupils were filled with surprise.
However, whether in bed or on the battlefield, she was never the type to give up easily.
Even when facing her own husband.
So she threw away the ninja sword she was holding, and a sword fell from the sleeve of her kimono.
It was the spirit blade Beast Cutter, and its blue hilt perfectly matched her kimono.
A weapon made of extremely rare special chakra metal — undoubtedly a divine artifact-level ninja tool.
Kichou gripped the hilt and drew the blade.
The brilliance of the blade was dazzling, as if the blade touching the air was cutting through it.
Then, she took a deep breath.
The blood vessels around her eyes bulged, and a faint rainbow appeared deep within her pure white pupils, emitting an extremely pure white light.
Kichou’s figure once again fluttered like a butterfly, matching her purple and white kimono and making her look as if she were using a magical spell against Yayoi.
Shiiing.
The sharpness of Beast Cutter was clearly superior to the previous standard ninja sword, and it easily cut through Yayoi’s chakra armor.
Blood began to spurt from Yayoi’s chest.
After cutting through the chakra armor on his body, it also cut through the flesh of his chest.
As the blade departed, white steam rose from the wound on Yayoi’s chest and healed in an instant.
In this state, not only explosive power but also recovery ability was enhanced.
“That’s really terrible, husband.”
Kichou did not take her eyes off the white side, unsure whether she was marveling at Yayoi’s chakra armor defense or at his miraculous self-healing ability without wounds.
However, regardless of the type, if a ninja acquired even one of them, it could be called powerful.
Kichou could not imagine the despairing expressions of enemies who had broken through Yayoi’s chakra armor and witnessed his strange self-healing.
Do not forget that her husband was also a top-class puppeteer at the time.
Do you think puppets are the trump card?
No, in fact, his trump card is physical ability.
Do you think physical techniques are the ultimate trump card?
No, behind that there is also chakra armor that can shatter even ninjutsu in one blow.
In the end, after breaking through the chakra armor, what she saw was a body that began to heal without using medical ninjutsu.
How cruel.
“You’re exaggerating.
Yayoi looked at his wife, at a loss for words.
Every part of Beast Cutter was made of special chakra metal, the crystallization of lost craftsmanship and the efforts of ancient top craftsmen.
With a standard ninja sword and Beast Cutter, one could cut through.
What was even worse was that Kichou had opened the Byakugan, directly seeing through the flow of chakra in the armor and easily finding the weak points.
If he had not stepped back half a step, the amount of bleeding from his chest would have been even greater.
It was not fatal, but it still hurt quite a bit.
“Ah, this is Kichou’s love for her husband.”
Kichou said this.
Tonight, Yayoi intended to give her a harsh lesson.
Even if she begged for forgiveness, he would roll his eyes.
Hmm, even if he did not roll his eyes, she would roll her eyes.
“By the way, husband’s technique is just like a Tailed Beast.”
Kichou sheathed Beast Cutter, but her Byakugan remained open.
She carefully examined the chakra armor on Yayoi’s body and found several clues.
“After all, it’s a technique developed by imitating a Tailed Beast’s cloak.
This mode activates the chakra inside the body to its limit and releases it to wrap around the outside, greatly enhancing both defensive and destructive power, and comprehensively amplifying taijutsu, ninjutsu, and genjutsu as well.”
Yayoi nodded.
The inspiration for this chakra armor did not come from the Fourth Raikage’s Lightning Release Chakra Mode, but from Uzumaki Naruto unleashing the Nine-Tails’ chakra and forming a Tailed Beast cloak.
Thinking about it carefully, the activated chakra he extracted was similar to a Tailed Beast in many ways.
The life characteristics of the created Irori were also close to chakra creatures like Tailed Beasts.
It was only natural that Kichou would roll her eyes — it was as expected.
“A good idea, but it places a heavy burden on the body.
Furthermore, such a large-scale external release consumes a massive amount of chakra.”
Kichou provided an accurate assessment.
With such dense chakra, if an ordinary ninja wore it, they would die.
Only ninjas with strong bodies like Yayoi could handle it.
“The burden is not a big problem.
If I train my body a little, I can perfectly master this technique.
As for chakra consumption — no, this technique suits me best.
My chakra evaporates very slowly, so once released, it can be stored for a long time.”
Yayoi said this.
Following Yayoi’s reminder, Kichou immediately recalled that Yayoi had previously used external chakra groups to wirelessly control puppets.
Generally speaking, once chakra was released, it would immediately evaporate into the air.
To use Yayoi’s chakra armor, he had to constantly release high-density chakra outward.
To maintain this consumption, a vast amount of chakra would inevitably be required.
For example, the Lightning Release Chakra Mode passed down in the Land of Lightning produced Lightning Release-type chakra and formed lightning armor worn on the body.
He had to constantly release chakra to keep the lightning armor moving.
Only those with chakra close to or at the level of a Tailed Beast could freely use this Lightning Release mode.
The ninja “A” of the Land of Lightning was the strongest on this path and possessed chakra on par with a Tailed Beast.
It was said that his Lightning Release Chakra Mode could blow away Tailed Beasts with his fists or defeat them in hand-to-hand combat.
However, Yayoi was different.
His chakra evaporated very slowly, and as long as he formed the armor, he could maintain it for a long time without constantly releasing chakra to move the armor.
This was equivalent to released chakra.
As long as it was not canceled by enemy attacks, it could be stored for a long period without additional loss.
That was why Yayoi could maintain this state for a long time even without Tailed Beast-level chakra.
Kichou immediately noticed that.
As Yayoi said, this technique suited him best.
Compared to the Lightning Release Chakra Mode of the Land of Lightning, it was closer to a Tailed Beast outer cloak, closer to a jinchūriki.
However, these two chakra armors ultimately aimed for the same purpose.
Namely, using high-density chakra to transform the body into a dangerous weapon that combined attack and defense.
“Actually, this technique has further development potential.
That is, injecting chakra into nature transformation to enhance the technique’s destructive power.”
Yayoi answered this way.
Like the Rasengan, Yayoi’s technique was a basic technique and could be further extended.
The high-density chakra surrounding the body was different from the Lightning Release Chakra Mode and had no change in chakra nature.
What if nature transformation was injected based on this standard…
It would be the same as wearing a Wind Release: Rasenshuriken for battle.
At that point, the power and difficulty of that technique would naturally surpass the Lightning Release Chakra Mode.
However, Yayoi did not currently have the courage to complete the nature transformation.
Currently, the power of the basic technique already surpassed the Rasengan.
If nature transformation was injected, its power would naturally surpass Wind Release: Rasenshuriken.
Wind Release: Rasenshuriken was a very high-risk ninjutsu.
If he wore a ninjutsu even more powerful than Wind Release: Rasenshuriken on his body, not only would he fail to defeat the enemy, but he would first cripple himself.
“Um…
It sounds dangerous.”
Injecting nature transformation into high-density chakra armor — just thinking about it sent a cold chill down Kichou’s spine, and cold sweat ran down her forehead.
Bestowing chakra was an advanced chakra control technique that required a certain level of ninja.
On this premise, incorporating nature transformation increased the difficulty and risk exponentially.
“Unfortunately, only after my body and chakra experience a new qualitative change can I attempt to inject nature transformation.”
After all, Wind Release: Rasenshuriken was something held in the hand, while the technique was always worn on the body.
The level of difficulty and risk was simply not on the same level.
“Does this current technique have a name?”
Kichou asked with interest.
Naming one’s original technique was one of the joys of being a ninja.
Yayoi placed his hand on his chin, thought for a moment, then looked up at the sky with a deep gaze.
“This technique…
Let’s call it Chakra Armament Mode.
Someday, this technique will become famous in the ninja world along with me.”
Yayoi gave the ninjutsu he had created an official name and looked forward to the day it would become famous in the ninja world.
His fame had already spread to many neighboring countries, but he wanted more.
A small goal to make a name for himself in the ninja world was to reach the same level as Senju Hashirama and Uchiha Madara.
