Unexpected

"Hello, my name is Uchiha Issei, and I come from another world."

Issei walked up to Orochimaru and thrust his fist at him.

"Another world?" Orochimaru's eyes lit up. More than surprise, he was curious about the unknown, so he stretched out his fist and bumped it with Issei's.

Soon, Orochimaru understood the cause and effect of the matter, as well as the Cell Technology and information about the other world that he was most interested in.

After the group finished their discussion, they headed towards the ANBU Headquarters in the center of Konoha.

The Anbu is no longer as mysterious as it used to be; it's more like an elite department that specializes in carrying out high-difficulty missions and reports directly to the Hokage.

Just as everyone emerged from the forest and arrived at the west gate of Konoha, Issei paused, his expression subtly changing.

"What's wrong?" Sasuke asked, puzzled.

"It's nothing, let's go to the ANBU Headquarters first." Issei shook his head and didn't say anything more.

However, he was not at peace, because just now, he suddenly could no longer sense Anrokuzan's location.

Before entering this world through the Dragon Vein, he had Anrokuzan infuse a small amount of his own blood into him. Even if Anrokuzan entered this world first, Issei could still sense Anrokuzan's presence across the entire world.

The sudden loss of blood ties with Anrokuzan made Issei wary.

Either Anrokuzan was killed, or he was trapped in another dimension, and someone deliberately severed Anrokuzan's blood ties with him.

If it's the former, then it doesn't matter. Anyway, Issei only needs Anrokuzan to come to this world and let him explore the way first. As for how to get back, he certainly has a way.

But if it's the latter case, the person who can sever his bloodline connection must be extremely powerful.

Let's turn to the other side of the story.

Beyond the Shinobi World, in Alternate Space.

Kara headquarters.

From a strangely shaped platform, figures gradually emerged.

Each one was not a physical entity, but rather a 3D model that resembled a projection. These people were all shrouded in black robes, making it impossible to see their appearance.

A mocking voice rang out first. "It's rare to see so many people appear together. What happened?"

"I've summoned you all to make sure you pay attention to Konoha."

A deep voice rang out, and a tall figure dressed in a white haori with a black cloak appeared in the center of the platform. His hair was gathered on top of his head and styled into a small braid resembling a rat's tail. The Roman numeral IV was tattooed below his left eye, and he wore a red earring. He looked calm and aloof.

This is the only person whose true form appears on the high platform, and he is none other than Jigen, the leader of the Kara.

"Konoha? Isn't Kashin Koji watching over there?" Victor asked, puzzled.

"Kawaki is still in Konoha, seemingly safe and living a good life. Should we make a move on him now? I'd like to teach those Konoha trash a lesson," Delta said with a mocking expression.

Jigen shook his head slightly and said in a deep voice, "It's enough to just monitor Konoha's movements. Also, find an opportunity to capture a ninja named Uchiha Issei, and make your move after he leaves Konoha."

Seeing Jigen's serious expression, Delta stopped her nonchalant attitude and said solemnly, "Could it be that this Uchiha Issei has the qualifications to become a ' Vessel '?!"

"Yes, I want to live. Amado, you come and help too." Jigen nodded, without saying anything more.

"I can go to Konoha by myself; I don't need Victor and Amado to get in my way."

"Delta said dismissively."

"Delta, you're too impulsive. I'm worried about you. This is an order, and failure is not an option! Amado will lead this mission."

Jigen's expression was indifferent, and although his tone was calm, the others felt a chill run down their spines.

"Yes!"

"Yes."

Victor and Amado, standing to the side, said respectfully.

Although Jigen is usually very polite and has a peaceful personality, he becomes ruthless and unscrupulous when it comes to important matters.

Even the usually unruly Delta remained silent, no longer daring to refute.

"Go," Jigen said calmly.

On the high platform, the projections of the figures gradually faded away.

Jigen remained calm. The moment he lifted his foot, a black hole with a diameter of more than three meters appeared in the space in front of him.

He stepped in, and his entire body vanished.

The next second, a black hole appeared in another room in the space, and Jigen walked out.

At this moment, on the bed in the room lay a middle-aged man with closed eyes, a rugged face, and a thick beard. This was none other than Anrokuzan, who had disappeared from Issei's bloodline perception.

Looking at the unconscious Anrokuzan, Jigen's expression gradually darkened.

A thousand years ago, Ōtsutsuki Isshiki was ambushed by Kaguya and was critically injured. Most of his body was sacrificed to the Divine Tree by Kaguya.

In a moment of crisis, he used the Otsutsuki Clan's secret technique, the Karma, to transfer his soul and Chakra together, parasitizing the body of the passing monk Jigen, and taking over his body.

The Karma is a unique ability originating from the Otsutsuki Clan. Members of the Otsutsuki Clan can replicate themselves and digitize their own data, then implant it into another person's body. The person into whom it is implanted is called a "vessel," and a black diamond-shaped mark will appear on the palm of the "vessel" as an initial symbol. This mark is the "Karma."

The 'Karma' is a compressed 'backup file of the Otsutsuki.' The compressed file will be 'decompressed' little by little over a long period of time. It can also be 'decompressed' faster through battle. When all the data is 'decompressed,' the 'vessel's' body will be 'overwritten' by the Otsutsuki's own data, and the 'vessel's' own existence will completely disappear. The Otsutsuki will thus be resurrected.

As long as the wedge remains, Otsutsuki is essentially immortal.

Ōtsutsuki Isshiki used Jigen's body as Vessel to lie dormant and slowly nourish his wounded soul.

Because Jigen's body is native to this planet and lacks strength, it has Isshiki patched up over thousands of years, leaving Jigen riddled with holes.

Despite having used it for a long time, Isshiki had long wanted to change his body.

However, even though he was dissatisfied, he couldn't find a better body, so he just made do with what he had.

To this Isshiki, he created the Kara, hoping that its members would find suitable Vessel for him.

The Vessel not only holds Isshiki's Chakra, but also provides him with nourishment, paving the way for his complete resurrection.

Just as the maturation of the Divine Tree requires the life force of the planet, the resurrection of the Isshiki requires absorbing everything from its Vessel.

Isshiki has always operated in the shadows under the identity of Jigen, and he doesn't care much about ninjas.

Furthermore, Kaguya sacrificed most of his body a thousand years ago, and he lost his most primal Chakra, so Isshiki needs time to slowly recover.

The various ninjutsu techniques used by ninjas are completely useless against the abilities of the Otsutsuki Clan; he can absorb all ninjutsu.

His Taijutsu were something that those native humans could not achieve even after a lifetime of training. If he hadn't completely disregarded the possibility that Kaguya would dare to ambush him, he wouldn't have had to lie dormant on this planet inhabited by inferior beings for a thousand years.

To Isshiki's surprise, Kaguya was sealed away by the descendants of this world, and the seal was broken a thousand years later.

Isshiki's attention was that ninja named Madara. Despite being a lowly being, he displayed terrifying power after obtaining the strength of the Otsutsuki Clan.

In particular, Madara's Chakra is vastly different from Kaguya's, and even from his peak performance. However, Madara's fighting prowess is Isshiki that cannot be ignored.

So ever since then, Isshiki Jigen Vessel secretly search for a new Vessel, while preventing himself from being discovered by the ninjas.

Although he felt that Naruto and Sasuke were no longer a threat to him after Madara's death, he had become much more cautious after being ambushed by Kaguya. He wouldn't personally take action unless he was absolutely certain.

In particular, outside the ninja world, there is a place called the Pure Land, where Kaguya's descendants are still hiding.

To prevent Kaguya's descendants from causing trouble, Isshiki needs to continue nurturing his current Vessel before he can be fully resurrected.

The remaining will that originally belonged to Jigen had been almost completely worn away. Even Isshiki himself did not expect that the will of a monk could hold out against his remaining Chakra for a thousand years.

What has happened recently has left Isshiki feeling rather bewildered.

He actually discovered the bloodline power of the Otsutsuki Clan within the body of another inferior being.

Although this force is very weak and scarce, like a drop of water in a lake.

But this bloodline power was so pure, even purer than Isshiki's own bloodline power.

This is Isshiki that cannot be understood.

Even his peers in the Otsutsuki Clan, such as Momoshiki, were only slightly higher in status than him, and their bloodline purity was at most similar to his.

But this human being, whom Isshiki sees as nothing more than livestock, was able to perfectly integrate the bloodline of the Otsutsuki Clan, which Isshiki found hard to understand.

So Isshiki brought Anrokuzan back to the Alternate Space and found that a power had been applied to his body. According to ninjas, it was Genjutsu, but in his opinion, it was just an ability that arose after the power of the Divine Tree and the Otsutsuki Clan had degenerated too much.

Moreover, after invading Anrokuzan's soul, Isshiki discovered an astonishing secret.

In a world beyond theirs, there exists another world with similar figures.

"The strongest beings in that world were an ordinary human ninja and a woman who had adapted to the power of a fox. I just wonder if there's another version of myself in that world."

Looking at Anrokuzan lying unconscious on the bed, Isshiki suddenly had many thoughts.

According to Anrokuzan's memory, that world was very similar to this one.

Therefore, Isshiki is speculated that he might also exist in that world, along with people like Kaguya, Momoshiki, Kinshiki, and Urashiki.

If his speculation is correct, if he had been resurrected in this world earlier, he could have easily invaded that world, found Kaguya who was still sealed on the moon, replanted the Divine Tree, and sacrificed Kaguya.

Most importantly, he can find his counterpart in another world and then completely absorb his Chakra before he recovers.

At that Isshiki, he will be able to return to his peak form and become even stronger.

When Momoshiki, Kinshiki, and Urashiki arrive, he will be able to handle all three of them by himself.

Although the Otsutsuki Clan has a strict hierarchy, if someone's strength surpasses that of the Main Family members, as long as they hand over the Divine Tree Fruit on time, the old folks in the clan won't interfere too much.

After all, it is very difficult to truly and completely kill an Otsutsuki Clan Member. Even if the physical body perishes, it is difficult to completely eliminate the Chakra. With the presence of Karma, resurrection is only a matter of time.

Therefore, the competition among peers is fierce, and the weak may even be directly transformed into Chakra Fruit and merged with the strong.

Is the Dragon Vein Seal?

Isshiki reached out and placed his hand on Anrokuzan's body. Soon, Anrokuzan was completely absorbed by him.

Originally, this Isshiki of skill was not required, but although Anrokuzan's bloodline was pure, the amount was too small. Only by absorbing it completely could he obtain it without any waste.

"Um?"

Just as Isshiki had completely absorbed Anrokuzan and began to refine the Shiraha Bloodline within his body, he suddenly sensed the soul consciousness contained within the bloodline, and his entire body abruptly froze.

"What's going on?!"

Isshiki's body trembled violently. He could feel a power within his bloodline, as if it wanted to force its way into the depths of his soul and merge with his Original Chakra.

This unusual situation immediately sent chills down Isshiki's spine. His instincts told him that he could not let this power intrude, so he fought against it with all his might.

A strong sense of crisis Isshiki Jigen to activate the power of the 'wedge' within Jigen's Vessel.

Because the selection of the 'vessel' for the Karma has extremely strict requirements, if the 'vessel' has a defect, it will not be able to withstand Ōtsutsuki Isshiki's Chakra during the reincarnation process, which will result in Isshiki not being able to be fully resurrected and will die a few days later.

Jigen, as Vessel, is not of high quality.

Therefore, Isshiki it's not necessary to use Jigen's power, then it's best not to. He'll have to change Vessel sooner or later, so it's important to ensure that too much Chakra isn't consumed within Jigen's body.

Isshiki can delay the time of reincarnation, but now he is facing a huge crisis. If he does not resolve the problem of the bloodline he just absorbed, his body may collapse now, causing the wedge to be 'decompressed' prematurely.

This will cause Jigen's Vessel to automatically enter a state of reincarnation, and even Isshiki cannot control this process. This is the only flaw of the secret technique 'Wedge'.

As Isshiki activated the power of the Karma seal, his Chakra surged rapidly, numerous black marks appeared on his body, and a long horn grew from the top of his head. His aura was completely different from before.

Under the crushing force of his powerful Chakra, the soul aura contained deep within his bloodline was completely obliterated.

"It was formed by the fusion of two forces."

As he closed the power of the wedge with Isshiki, he saw cracks appear in the black crystal on his lower abdomen, and his face instantly darkened. He had been too careless. The Otsutsuki Clan had an inherent sense of superiority as superior beings, which made him never think that an accident would occur when he absorbed a small amount of pure bloodline power from Anrokuzan's body.

The Chakra expenditure was negligible for him, but it did cause some damage to his Vessel. He gained nothing but suffered a loss.

"If we capture that human named Uchiha Issei, we should be able to find out the source of his blood. Another world... it seems quite extraordinary as well. We can no longer afford to be careless."

PS: I won't write much Boruto: Naruto Next Generations; it's just a setup for the Otsutsuki Clan. As for the new generation of characters like Boruto, I won't write about them. Actually, the Boruto: Naruto Next Generations is alright, but the anime has a lot of original content, which is terrible. There are only a few days left, and I still have two chapters to catch up on. The pressure has instantly fallen on the young Three-Session Beast.
