I became Hokage in Tokyo

Chapters 426 and 427: Tianyuan Game

As he opened the Gate of Life, the third gate of the Eight Gates Formation, Kai's forehead veins bulged, his face turned crimson, and his entire face became as ferocious as a red demon.

Even after two months of training, this body was still too weak. A sharp, tearing sensation in the muscles kept coming from all over the body. Opening the gate of life was the limit, and it could only be maintained for a very short time.

We must finish this quickly!

"Leaf Whirlwind!"

With a heavy stomp of his hind foot on the ground, a muffled explosion rang out, and the figure shot out like an arrow released from a bow.

"Damn it! You brat, you actually knocked over the big rock!"

Firelight gritted his teeth and rushed forward with incredible speed. With a flick of his right arm, a sword tip emerged, biting towards Akai's throat like a venomous snake.

Victory or defeat, life or death, can be decided in an instant!

"Okay, that's enough. Let's stop here."

Just then, a coquettish voice rang out, and Akai and Huoguang were strangely frozen in place, surrounded by black energy, unable to even move their fingers.

A gentle breeze blew by, ruffling the woman's black bathrobe, which resembled both a mourning dress and a wedding gown, revealing her slender and graceful curves.

"Although I wanted to play a little longer, an unexpected change occurred..."

Kuro Seimei turned his head, his purple eyes gazing thoughtfully into the distance, a slight smile playing on his lips:

"Let's speed things up a bit."

With a wave of her slender hand, Kurogane Kouzo felt a chill run through his body, and a blurry, illusory male figure flew out from within him. The outline of Mr. Kai could be vaguely seen on that face.

"Return the item to its rightful owner."

The shadow ninja residing in Kurogane Kouzo's body was transformed into a small black ball of light, which Kuro Seimei picked up and swallowed in one gulp.

"Mr. Kai!" Black Iron Light roared, his eyes bloodshot.

Immediately afterwards, Kuro Seimei snapped his fingers, and Kuro Teizo felt his vision go black and the world spin around him.

Almost at the same moment, Kougi Kozo and Tosu Hideo appeared one after the other at their base in Kobe's New Port District.

"Minister Tosu, are you alright?"

"You and Black Iron suddenly disappeared for three days and two nights, which really scared us!"

"Quickly report to the authorities that they're both back!"

The appearance of the two immediately alerted the supernatural police officers who were guarding the spot, causing a chaotic scene.

"It seems I've been kicked out of the secret realm by Abe no Seimei?"

Hero Tosu touched his chest with lingering fear, seemingly trying to determine the number of hearts.

"Mr. Kai! Mr. Kai!"

Kurogane Kouzo looked around blankly, but did not receive a response from Kai as usual, leaving him feeling empty inside.

He suddenly raised his right hand and looked at the back of his hand. The bright red curse mark had disappeared, and two streams of hot tears fell down his cheeks.

"Mr. Kai's heroic spirit is gone..."

-

Inside the Kannabi Bridge Secret Realm dungeon, with the departure of Kurogane Kōzō and Tori no Hideyoshi, Kuro Seimei's delicate body also vanished like a bubble.

A pair of magnificent Mangekyou Sharingan appeared in mid-air.

"Is this all the potential there is for a Shadow Ninja...?"

Naruto Uchiha stared coldly at the black-haired spiky man on the ground, a hint of disappointment in his eyes.

The Shadow Ninja is a fragment or remnant extracted from Naruto Uchiha's ninja recruitment by the system, much like the Shadow of Evil, the ashes after a soul has burned.

Even so, the souls of Shadow Ninjas are far more powerful than those of ordinary people.

Just like how Uchiha Naruto used Hikari and Oishi, two Jonin from Iwagakure, as shadow ninjas, without any intervention, and placed them in the bodies of ordinary people, the fragmented memories, emotions, personality, and combat experience of the shadow ninjas directly smothered the original owner's self-awareness and took control of the body.

Kurogane Kouzo was able to maintain his individuality and coexist with Guy's shadow ninja form, thanks to Uchiha Naruto's mercy.

Naruto Uchiha currently has two methods for creating superhumans. The first is to use master-disciple assistance to impart ninjutsu, and the second is to have shadow ninjas reside in bodies that are ordinary people.

Although the growth potential of Shadow Ninjas after gaining physical strength is not as good as that of those who use master-disciple assistance in battle, they can create a large number of cannon fodder at once.

Naruto Uchiha originally intended to use this opportunity to create a shadowy army of ninja, which is why he chose Kobe City, where the natural energy of the earth's ley lines is relatively abundant, as the stage to wage a fake Holy Grail War and test its strength.

However, after obtaining the Impure World Reincarnation technique, Naruto Uchiha's thoughts underwent a subtle change.

Naruto Uchiha glanced at the firelight lying on the ground, then looked at the boulder that had been kicked to pieces and was now dead, and formed hand seals.

"Impure World Reincarnation".

The flesh and blood left on the ground by the large stone were used as the wedge for the impure earth reincarnation and the vessel of fire was offered as a living sacrifice.

"Aaaaaaaahhhhhh!!"

The hedgehog-headed creature let out a heart-wrenching scream, and then countless dust and scraps of paper covered its body, gradually blurring its shape and face and transforming it into another person.

A moment later, a large, protruding face appeared before Uchiha Naruto.

"This...this is Kannabi Bridge?! Wasn't I killed by that Sharingan brat?!"

With his underbite wide open, revealing the distinctive black hair and whites of a reincarnated being, he asked in surprise and uncertainty.

"Okay, okay, don't rush."

Naruto Uchiha pulled out a kunai with a talisman on it and plunged it into the back of the underbite's head, completely erasing his will.

Oishi, a Jonin from Iwagakure, was skilled in using the Camouflage Invisibility Technique, a secret technique similar to the Transparent Release, to conceal his identity. During the Battle of Kannabi Bridge, he kidnapped Rin Nohara and blinded Kakashi's left eye. In the end, he was killed when Obito Uchiha, who had awakened his Sharingan, saw through his invisibility technique.

Da Shi was like a clay puppet, his eyes empty and motionless.

"drink."

Naruto Uchiha raised two fingers of his right palm and let out a low shout.

The manipulated boulder mechanically formed a hand seal, its figure dissolving into the air like camouflage.

Camouflage invisibility!

"They actually managed to summon a Shadow Ninja after he was given a physical body using the Impure World Reincarnation technique."

Naruto Uchiha couldn't help but show a hint of excitement, and the corners of his mouth turned up slightly.

The existence of a Shadow Ninja after being given a physical body is very special. Although the body is still that of a mortal, the soul is like the "wine and sewage effect," merging with the Shadow Ninja and becoming inseparable.

If a person dies while still in a physical state, the soul summoned by the Impure World Reincarnation will remain fused with the Shadow Ninja and then attach itself to the living sacrifice.

My wild idea actually became a reality.

Since we can exploit this bug with the Impure World Reincarnation technique, we have to scrap the previous plan and start all over again.

"It's better to have an immortal, resurrected army than a flesh-and-blood shadow army."

Naruto Uchiha's kaleidoscope eyes spun, and he remained silent, lost in thought.

Originally, there were no superhumans in this world. The current Twelve Divine Generals and members of the Hawk are either related to Uchiha Naruto or were handpicked by him. Naturally, he would not be so cold-blooded as to kill them and turn them into the Impure World Reincarnation army.

Using Shadow Ninjas to create an army of Edo Tensei (reincarnated) ninjas is much simpler and easier.

Unfortunately, ordinary people used as sacrifices in the Impure World Reincarnation will cause the resurrected superhumans to experience a rapid decline in power.

All sacrifices to the Shadow Ninja should ideally be Shadow Ninjas who have undergone physical transformation.

As a result, half of the Shadow Ninjas had to be lost.

Even so, this deal is still worthwhile.

Besides their immortal bodies, the resurrected dead through the Impure World Reincarnation have another outstanding advantage: an endless supply of chakra!

"Give it your all!"

At Uchiha Naruto's command, the resurrected Jonin from Iwagakure immediately clasped his hands together, and a powerful burst of chakra erupted forth, sweeping across the surroundings like a strong wind.

If an ordinary person were here, they might be terrified by the sudden burst of chakra.

Uchiha Naruto, however, remained calm and observed the resurrected Kage with great interest.

A full minute passed, and the chakra erupting from Oishi showed no signs of weakening, like a volcanic eruption with no bottom in sight.

"This is terrifying! The Impure World Reincarnation technique is practically a perpetual motion machine of chakra!"

Naruto Uchiha couldn't help but praise the Impure World Reincarnation technique invented by the Second Hokage, saying it was simply too good to be true.

If a Jonin with normal chakra levels were to go all out for a minute like this, their chakra would be completely depleted, and it would probably take them most of the day to barely recover.

Those resurrected through the Impure World Reincarnation do not feel fatigued, and their chakra is inexhaustible.

Chakra is an energy source that is more efficient than fossil fuels and cleaner than solar energy.

A Jonin-level resurrected corpse, using the Impure World Reincarnation technique, provides a continuous flow of chakra; one person alone is enough to supply electricity to an entire town.

"Compared to the natural energy from the earth's ley lines, the chakra energy of those resurrected through the Impure World Reincarnation technique can provide a more stable supply of energy for the barrier."

Naruto Uchiha sensed the surging chakra of the Jonin from Iwagakure and nodded slightly.

Naruto Uchiha had long planned to set up a large barrier throughout Japan that could monitor supernatural beings.

In this way, any disturbance in Japan after the Scarlet Moon Incident can be observed as easily as reading the lines on the palm of one's hand.

Although Naruto Uchiha's barrier ninjutsu is at its maximum level, he is unable to set it up because he cannot guarantee the energy source to maintain the barrier.

He initially set his sights on the natural energy within the earth's veins.

Unfortunately, after a period of experimentation, it was found that the natural energy in the Earth's veins is too weak. A single vein node is still insufficient to automatically and continuously cover a reconnaissance barrier of tens of thousands of square kilometers 24 hours a day.

After Naruto Uchiha witnessed the wonders of the Impure World Reincarnation technique, a turning point finally appeared.

Using the endless chakra of the reanimated to replace the natural energy of the earth and supply the reconnaissance barrier with magic—this demonic plan is highly feasible!

"Although they all possess an endless supply of chakra, the power levels between ninjas are completely different."

With a wave of his hand, Naruto Uchiha stopped the burst of chakra and returned to normal.

"If the chakra output of an ordinary ninja is equivalent to that of a car, then the Kage-level ninjas are like battleships. As for the Tailed Beasts, they are even more terrifying than nuclear-powered aircraft carriers, capable of powering an entire nation."

After careful calculation, Uchiha Naruto determined that at least five nodes would be needed to create a large barrier capable of covering Japan.

Each node requires at least one Kage-level ninja to be stationed there, serving as a chakra battery.

Or around ten Jonin-level Kage ninjas; if they are Chunin or Genin, then there must be more than a hundred.

Naruto Uchiha was calculating the list of Kage he had obtained through the ninja recruitment.

Although there are hundreds of them, their quality is generally average. There are only a handful of Kage-level powerhouses like Guy, and the vast majority are just low-level ninjas like Chunin or Genin.

If all these Shadow Ninjas are consumed, it might be barely possible.

"A large number of containers are needed, which may require more than 500 people."

Both the flesh-eating of Shadow Ninjas and the living sacrifices of Impure World Reincarnation require a vessel.

Unlike the previous experiment in Kobe City where a few scumbags were randomly chosen as vessels for the Shadow Ninjas, consuming so many people at once is not such a simple matter.

If possible, Uchiha Naruto would try to avoid involving ordinary citizens, after all, he wasn't some kind of demon.

"A great reward will surely bring forth brave men, and fortune is found in danger."

Uchiha Naruto pondered for a moment, then suddenly shook his head and smiled:

"On one side lies the bright path to transcendence, on the other, the abyss of eternal damnation. Let them make their own choice. Those who are willing will take the bait."

Naruto Uchiha pulled out a scroll, put away the resurrected Jonin from Iwagakure, and then left the secret realm.

"Using Abe no Seimei's fabricated world-destroying plan, I will carry out my plan to create an army of reanimated beings and establish a grand barrier. I call it 'Gurren Lagann'!"

Back in his secret realm at the Uchiha Ruins, Naruto sat on a stone throne, preparing to get up and check on Jeanne.

Just then, faint, muttering sounds echoed in Uchiha Naruto's ears:

"A king who does not belong to this world, you are the master of Crimson and the Rinnegan, the ruler of all things in the unity of Yin and Yang..."

Naruto Uchiha's expression changed drastically, as if he had seen a ghost.

Among the ninjutsu he currently possesses, there are those capable of transmitting sound over long distances, such as the Spirit Transformation Technique.

However, Naruto Uchiha was able to hear the offline communication from anywhere, even on the other side of the earth, thanks to the bond built through the cooperation between master and disciple.

Naruto Uchiha is the connection between all extraordinary individuals and the superhumans. Only extraordinary individuals can communicate with him directly; ordinary people cannot sense him even if they chant his name.

Furthermore, the "Anti-Membrane" that he opened up to the Eagle Organization was a teleportation channel that was opened after the master and apprentices upgraded their combat skills, allowing them to be transferred from reality to the Ark in an instant.

However, only the Hawks knew about the three names that Naruto Uchiha had set as the key. When did the news leak out?

Moreover, the voice sounded extremely familiar.

"A king who does not belong to this world, you are the master of Crimson and the Rinnegan, the ruler of all things in the unity of Yin and Yang..."

Naruto Uchiha's expression grew increasingly strange, and the corner of his mouth twitched.

No way...

It's actually the immortal sect calling me?
