Warlock Invasion of Naruto.

Upon reaching the depths of the desert in the Land of Wind, one could clearly sense that the area of ​​the desert oasis had expanded considerably.

It seems that the world is indeed focusing on economic development. In fact, if ninjutsu were applied to production, the short-term productivity that ninjas could generate could be a hundred or even a thousand times that of ordinary people.

Of course, when it comes to technological development, the most crucial element is the mind, not chakra.

Even ordinary people with no chakra talent can gain the ability to refine chakra through cell experiments.

It must be said that this journey to the parallel world has been very fruitful. As long as all the experimental materials and scientific research technologies obtained are handed over to the main body, the journey will be complete.

No wonder all wizards have an almost obsessive passion for exploring the unknown world. An unknown world may have many risks, but risks are often proportional to rewards.

Thinking of this, Issei reached out and touched the scroll in his pocket. It contained the remaining small amount of Urashiki cells. Most of the Urashiki cells were used up in the process of growing Sasuke's arm, but Issei also gained more proficient skills.

After negotiations, he obtained four more pairs of Mangekyou Sharingan from Kabuto's orphanage, as well as cells from a clone of Shin Uchiha.

These four pairs of Mangekyou Sharingan, with almost identical abilities and similar eye power, will become the focus of future experiments.

Since we've already mastered the complete cloning technology, if the experiment succeeds, the original body should also be able to clone more Mangekyou Sharingan, at which point we can conduct experiments on the Eternal Mangekyou Sharingan.

The only thing that worries Issei right now is that the Mangekyou Sharingan he and his original body have awakened is extremely powerful. Although it is at the same level as the Mangekyou Sharingan of the Uchiha Shin clone, the difference in power is huge.

"It's a pity that Orochimaru and Kabuto were unwilling to leave this world. Otherwise, they could have assisted in the experiments and accelerated the pace of technological breakthroughs."

Yicheng sighed inwardly.

Before leaving, he invited Kabuto and Orochimaru to return to the world where his original body was, but both of them refused.

Dou now only wants to take good care of the children in the orphanage and be a good director. He will only participate in and help with scientific research experiments when needed, and he is no longer willing to devote himself to the experiments.

When they parted, the only thing Kabuto said to Issei was to ask him to send his regards to Nonou in the world where his original self resided.

Upon learning that the dean of the other world was still alive and doing well, Kabuto seemed happy, but he didn't want to disturb him.

As for Orochimaru, his refusal was not firm, but he still decided to stay in this world.

Perhaps there are still things in this world that Orochimaru cherishes.

Ichisei did not force him to comply.

Everyone has their own ambitions, and besides, the gains from this trip have already been enormous.

Anyway, he acquired a lot of scientific research technology, and with Yakushi Nonou's talent, he can definitely help the original body. And Kabuto from the other world is obviously no worse than Kabuto from this world.

Once Orochimaru is subdued, a powerful research team will be formed.

......

Two days later, just as Yicheng arrived near the Loulan ruins where the dragon vein was located, he suddenly heard a deafening explosion coming from afar.

"This is..." As he watched the flames shooting into the sky in the distance, Ichisei's pupils constricted.

It seems his caution was absolutely necessary; such a commotion could only be created by a battle between at least Kage-level powerhouses.

Considering Sasuke's strength, Issei didn't plan to help. After Sasuke received the arm transplant, his physique, chakra, and eye power were all enhanced in all aspects. His right eye also evolved into the Rinnegan, and his left eye became the six-tomoe Rinnegan, whose eye power was above that of the ordinary Rinnegan. His current strength is probably firmly above that of the original Sasuke.

If Sasuke can win, he doesn't need help.

If he can't win, Issei will definitely not go.

With that in mind, he found his direction and headed towards the Loulan ruins he remembered. His immediate priority was to get back.

However, just as Ichisei arrived outside the ruins of Loulan, a fatal sense of crisis suddenly arose in his heart, and a feeling of goosebumps filled his entire body.

His jet-black eyes instantly turned crimson, and as the three tomoe appeared, they converged towards his pupils, transforming into a pattern of overlapping triangles that looked somewhat like an inverted pyramid made of building blocks.

Kaleidoscope Sharingan!

boom--!

The azure chakra instantly struck Issei's back. He was hit like a cannonball, and with a whoosh, his body spun forward and crashed heavily into a stone pillar ten meters away, embedding himself in it.

At that moment, a ninja wearing a black cloak with a red shirt and pants underneath appeared and stood in the spot where Issei had just stood.

He had short, silver-white hair, wore a white mask, revealing a high, straight nose, tightly closed lips, calm and indifferent eyes, and exuded a powerful chakra aura.

At his feet stood a red-skinned toad the size of a palm.

Looking at Issei, whose body was embedded in the stone pillar, Koshin Koji frowned slightly and slowly walked over. Although Amado had ordered him to capture him alive, he didn't like trouble, so as long as the target was alive, that was fine.

Moreover, the ninja that Jigen cared about was definitely not weak.

He just didn't expect his opponent to be so easily defeated.

Just as Guoxin Jushi reached the stone pillar, his body suddenly froze.

As his body embedded in the stone pillar, Issei's body slowly began to fade into nothingness and then disappeared.

puff!

The sound of a sharp blade piercing through flesh rang out.

Guoxin Jushi turned around and looked.

Issei, holding his ninja sword, pinned the red toad that remained in place to the ground and said, "You were hiding inside this toad just now, which is how you managed to avoid my senses. You have a very meticulous mind."

The moment he sensed the danger, Issei activated "Izanagi Ring," mainly because he had a warning, but he didn't expect the attacker to be able to bypass his senses.

This toad-summoning beast's abilities were too unique, so Issei killed it the moment he made his move.

"The Mangekyou Sharingan, that was your eye technique just now, Izanagi?!" Koshin Koji's eyes turned cold. To be on the safe side, he used a summoning technique to hide inside the toad's body before striking Issei with a single blow, but he didn't expect Issei's reaction to be so fast.

"You even know this?" Yicheng frowned slightly, and as soon as Guoxin Jushi finished speaking, he deliberately closed his left eye slowly.

This guy who suddenly appeared could also use the Rasengan, and his summoning beast was a toad that resembled a toad. His height, size, and the half of his face that was visible under the mask all reminded him of someone: Jiraiya, one of the Legendary Sannin.

In Naruto's memories, Jiraiya in this world had already died at the hands of his disciple Nagato, and his body had fallen into the deep sea, which is difficult for humans to reach. Therefore, the person in front of him is definitely not Jiraiya.

However, since cloning technology has already emerged in this world, and even the Mangekyou Sharingan can be cloned, it wouldn't be surprising if Jiraiya were cloned as well.

"It seems unlikely that I'll be able to get you to come with me directly."

Koshin Koji didn't say anything more. He formed hand seals, put the oil he had refined into chakra in his mouth, and spat it out while using Fire Release to ignite it. Multiple fist-sized, high-temperature fireballs flew rapidly toward Issei.

'Fire Release: Flame Bullet!'

The first move he made was a ninjutsu that Jiraiya often used.

"Are you a member of the Shell organization? Why did you arrest me? Did you kidnap An Lushan?" Yicheng retreated quickly, dodging as he asked. Although trying to communicate might not yield any results, he didn't want to try to find out if the person in front of him was a talkative person.

'Fire Release: Great Flame Bullet!'

Issei's response was an enhanced large fireball. Compared to ordinary fire-style ninjutsu, the fireball, made by burning chakra-refined oil, had a higher temperature, greater destructive power, and a significantly increased flight speed.

boom!

Issei dodged again, and the huge fireball landed on the ground. The viscous hot oil spread out but did not immediately seep into the ground through the sand. The flames remained on the surface of the sand for a long time.

Immediately afterwards, a series of fireballs rained down on Issei, seemingly unafraid of killing him.

Seeing that Kashin Koji had no intention of saying anything more, Issei finally became serious. With a large amount of eye power consumed, the silver-white chakra quickly materialized on his body.

Wow!

A huge, silvery-white arm suddenly swung out, easily sweeping away the pouring fireballs.

Kiss kiss...

The subsequent fireball struck the silver-white Susanoo, but it was like a drop of water falling into a lake; apart from faint ripples, it didn't even cause a splash.

Under the blazing sun, the silvery-white chakra seemed to emanate from a tangible form, appearing as a silvery-white metallic giant. Its growth and expansion were completed in a very short time.

"Susanoo?"

A flicker of emotion crossed Koshin Koji's eyes. He had thought he could easily defeat his enemy, but he hadn't expected that his opponent would possess the Mangekyou Sharingan of the Uchiha clan and use Susanoo so easily. It seemed that without getting serious, it would be impossible to capture his opponent easily.

'Toad Oil Bomb!'

Koshin Koji leaped away, dodging Susanoo's sweeping attack. His abdomen bulged, and then a large amount of thick, viscous toad oil was sprayed from his mouth, covering most of Susanoo's body with toad oil.

Issei immediately felt a sluggishness in Susanoo's body, as if its joints were locked up, making it very difficult to move.

Taking advantage of the influence of toad oil on Susanoo, Koshin Koji completed the hand seals before landing and slapped his hands on the ground.

'Escape from the Yellow Spring! '

The soft sand beneath Ichisei's feet suddenly turned into a flowing swamp.

Just as he was about to sink into the swamp, he suddenly leaped out.

When Koji saw the opening in Issei's Susanoo below his body, he immediately increased his chakra output, causing the area of ​​Yomi Swamp to expand rapidly, including Issei's landing point.

Immediately afterwards, Koji Kashin unleashed another Great Fireball, a massive fireball that blasted towards Issei from the gap beneath Susanoo.

After completing this series of combined attacks, Koshin Koji suddenly stood still with his hands clasped together.

Issei was somewhat puzzled, but after confirming Koshin Koji's strength, he no longer held back.

boom!

Before Issei landed, Susanoo grew again, its size quickly exceeding twenty meters. Its entire upper body transformed into a samurai wearing armor, and a giant snake-shaped sword appeared in Susanoo's hand.

Immediately afterwards, Susanoo expanded again, and a large amount of white chakra, almost tangible, gathered and condensed on Susanoo's body. Its already exaggeratedly huge size expanded once more, doubling in size from more than 20 meters to become a towering giant more than 40 meters tall.

The Susanoo, which originally only had an upper body, transformed into a complete human form, with two legs growing from its body, becoming a giant with three heads and six arms.

Susanoo - Fourth Form!

boom--!

When Susanoo fell into the vast Yellow Springs Swamp created by Koshin Koji using Earth Release, it splashed up a large amount of mud. The originally expansive swamp turned into a shallow beach under the forty-meter-high Susanoo, with a depth that barely covered Susanoo's calves.

With a simple wave of its hand, the fourth form of Susanoo extinguished the scorching flames. The sticky toad oil on its body, under the expansion of its enormous size, became like a small puddle of dirt, which could not affect Susanoo's movements at all.

"Huh? This is Sage Mode?!"

At this moment, Ichisei was about to attack Koshin when he sensed that the energy field emanating from Koshin's body had changed instantly, and the natural energy had become surging.

'Immortal method·Super large jade spiral pill! '

Kashin Koji, having entered Sage Mode, leaped into the air, raising his right hand. A ball of Sage Chakra gathered in his right palm, then expanded rapidly in the wind, its diameter exceeding three meters in an instant.

However, compared to the forty-meter-tall Susanoo, the Giant Rasengan is like a small ball.

As Issei watched Kashin Koji launch the attack, he urged Susanoo to raise the giant snake-shaped sword, which was more than ten meters long, and slashed down with force.

The moment the serpentine giant sword in Susanoo's hand struck the giant Rasengan, the Sage Art Rasengan suddenly expanded, and the surging chakra instantly engulfed the serpentine giant sword in Susanoo's hand, along with its arm.

boom--!
