Warlock Invasion of Naruto.

As an arm that refused to be transplanted with Hashirama cells in order to 'atone for its sins' back then, it lost the power of the Six Paths of Yin and did not receive any recuperation afterward. For the past ten years or so, it has been constantly exposed to the elements and has been working hard, resulting in a decline in its physical condition rather than an improvement.

Even if he transplanted an arm cultivated by Urashiki Otsutsuki and awakened the Rinnegan, even if he could potentially recover to his peak strength, it wouldn't be something that could be done in a short time.

"I understand." Naruto nodded and placed his hand on Sasuke's shoulder.

"This is......"

Sasuke was stunned for a moment. He felt an extremely pure Yang Release chakra enter his body. This was not Yang Release in the ordinary sense. It contained the power of the Six Paths. It was a power full of life force, which was directly repairing the hidden injuries left in Sasuke's body and the loss of life force.

"That's enough, Naruto. Doing this will deplete your own life force."

Sasuke couldn't help but speak up.

Although every cell in his body craved the Six Paths power that Naruto was transferring, Sasuke understood that this was because Naruto had just entered Six Paths Mode and recovered a large amount of Six Paths power.

It seems that losing this much life force is nothing to Naruto, but if they defeat Isshiki Otsutsuki, Naruto will definitely keep his promise and will use the power of the Six Paths to free the other tailed beasts.

Even if they manage to defeat Isshiki Otsutsuki, it's uncertain how much Six Paths power Naruto will have left.

Without the replenishment of the Divine Tree fruit and the so-called chakra pills of the Otsutsuki clan, the power of the Six Paths cannot be easily restored by time alone.

Having already consumed a large amount of Six Paths power, and then lost the chakra of the eight tailed beasts, Naruto would likely fall seriously ill like the Sage of Six Paths before him, remaining weak for several months, and the consequences might be even more severe.

"Sasuke!"

Sensing Sasuke's struggling strength, Naruto pressed down hard on his shoulder.

Naruto was more worried about Sasuke than himself. Sasuke could use the power of the nine tailed beasts to wield the power of the Six Paths, but Sasuke didn't have the power of the Six Paths Yin to replenish his strength and restore his power.

Back then, Sasuke was able to unleash the full power of the Rinnegan by relying on the power of the Six Paths Yin and the massive chakra of the eight and a half tailed beasts.

This is why Sasuke often experiences insufficient eye power and depleted chakra when using the Six-Tomoe Rinnegan.

The Rinnegan with six tomoe is too powerful; Sasuke, who has lost the power of the Six Paths Yin, cannot withstand this drain.

Based on various indications, Isshiki Otsutsuki's strength may be in no way inferior to Kaguya Otsutsuki's.

When they possessed the power of both Yang and Yin in the Six Paths, they barely managed to seal Kaguya with the help of Kakashi-sensei and Sakura.

Now that Sasuke has lost the power of the Six Paths Yin, he can no longer use the strongest sealing technique, "Six Paths: Planetary Devastation".

A simple Chibaku Tensei is not enough to seal Isshiki Otsutsuki.

To fight against Isshiki, a formidable enemy, Sasuke will definitely push himself to the limit and use the Rinnegan's abilities to the extreme.

Naruto, having regained Six Paths Sage Mode, can withstand all kinds of fatal blows, but Sasuke cannot. Therefore, Naruto is willing to sacrifice his own life force to help Sasuke.

“Naruto…” Sasuke looked at Naruto’s determined expression and didn’t say anything more.

Having known Naruto for so many years, Sasuke understood Naruto's personality all too well. Even though Naruto was no longer as impulsive and reckless as before after becoming Hokage, he was still a stubborn and persistent person at heart.

As a large amount of Six Paths power, brimming with life force, entered Sasuke's body, Naruto felt Sasuke's body gradually recovering. He then released his grip on Sasuke's shoulder and said:

"Sasuke, try to absorb my Sage Chakra, don't think about anything else."

Madara Uchiha once mastered the power of Sage Mode by absorbing the Sage Chakra of the First Hokage. After becoming the pseudo-Ten-Tails Jinchuriki, he even used Six Paths Sage Mode.

Unlike Naruto, who was able to use Six Paths Sage Mode after entering Six Paths Mode, Naruto mainly relied on the chakra voluntarily provided by the Tailed Beasts and the gifts from the Sage of Six Paths.

Madara learned the Six Paths Sage Techniques ahead of time thanks to the Six Paths inheritance that Black Zetsu deliberately leaked to him. That's why he was able to use various Six Paths Sage Techniques immediately after absorbing Hashirama's Sage Chakra and becoming Six Paths Madara. After all, Madara didn't have the Six Paths Sage who gave him a cheat code halfway through his journey.

Madara was able to successfully absorb Hashirama's Sage Chakra without suffering a backlash mainly because he had transplanted Hashirama's cells into him. His body fully adapted to Hashirama's cells, and he eventually awakened the Rinnegan by fusing Indra's and Ashura's chakra. Therefore, he had extremely high compatibility with the Sage Chakra within Hashirama's body.

The left arm that Sasuke has now re-transplanted mainly contains Urashiki Otsutsuki cells and Hashirama cells, as well as a small amount of Naruto cells.

Therefore, Naruto believed that with his help, Sasuke should be able to learn Sage Mode.

This can, to some extent, make up for the combat power lost by Sasuke due to the lack of Six Paths Yin Power and Tailed Beast Chakra.

“Okay.” Sasuke nodded, extended his fist and bumped it with Naruto’s. Feeling Naruto’s emotions quickly calm down, he also gradually calmed down and began to slowly absorb the Sage Chakra in Naruto’s body.

Sasuke's aptitude for learning Sage Mode is not bad; in fact, it could be said that he is second only to Naruto.

However, Sasuke cannot stop the flow of life during the cultivation of Sage Mode.

Now he can only learn Sage Mode by absorbing Naruto's Nine-Tails Sage Chakra.

This is something Naruto could only help Sasuke do if he used Six Paths Sage Mode.

Sasuke quickly adapted to the Sage Chakra that had entered his body and became familiar with how to use Sage Mode.

The threshold for cultivating immortal arts is extremely high, and the difficulty of cultivation is also outrageous. However, once you reach a certain stage, many things that seemed difficult to do before can be accomplished in just a few minutes.

"Sasuke, get used to Sage Mode and rest for ten days. Then we'll go find Ichishiki."

Naruto's aura weakened slightly, and he then withdrew from Six Paths Mode. Given his current state as a pseudo-Ten-Tails Jinchuriki, his aura was noticeably reduced, which shows how much life force he had just consumed.

Sasuke nodded solemnly; given their relationship, everything was understood without words.

He naturally hoped to win the fierce battle that followed. The best outcome, of course, would be for them to successfully eliminate Isshiki and then return to Konoha alive.

If things don't go as planned, at the very least he has to ensure Naruto survives.

The power of Sage Mode is not complicated, so ten days is enough time for Sasuke to fully adapt. In particular, his body has been fully restored to its peak state after being replenished by Naruto's chakra, but this is only a temporary state.

Finding a remedy as soon as possible is naturally the best choice.

......

On the other side, in another dimension.

In the desolate land, a magnificent palace complex stands, its style quite different from that of the ninja world.

This is the lair of Isshiki (Jigen). Other members of the Kara organization can only enter this place through 'Illusion Technique: Communication', but only Isshiki can come and go freely here.

At this moment, Isshiki was heading towards the bottom floor of the palace, preparing to absorb chakra as usual.

Victor, Amado, and Deluda have been missing for a long time, which means something must have happened, but Isshiki doesn't seem to care much.

"roar~"

When Shiki arrived at the bottom floor of the palace, the area was pitch black. A strange, enormous eye opened, and then the terrifying form of the Ten-Tails was revealed.

The appearance of Isshiki instantly aroused the Ten-Tails' emotions, causing it to open and close its mouth repeatedly towards Isshiki.

Ichishiki floated in front of the Ten-Tails, calming it down a bit.

At the same time, Isshiki began to absorb the Ten-Tails' chakra. Streams of deep red chakra, almost tangible, flowed continuously from the Ten-Tails' body and into Isshiki's body.

Every so often, Isshiki needs to absorb the Ten-Tails' chakra to maintain the vessel 'Jigen'. He is currently preparing for his resurrection, so he needs to absorb as much of the Ten-Tails' chakra as possible.

......

Ten days later.

Suddenly, ripples appeared in the space above the Ōtsutsuki Shrine, a dark crack appeared, and then a spatial gate with a diameter of more than three meters opened.

After resting for a while, Sasuke and Naruto arrived at the alternate dimension where Isshiki was.

“I sensed Isshiki’s chakra. He’s in the temple in front, and there’s a small Ten-Tails at the very bottom of the temple at the very back.”

After Naruto became the pseudo-Ten-Tails Jinchuriki, his perception was greatly enhanced when he entered Six Paths Mode, and he was able to know Isshiki's location.

The reason they took the initiative this time was to catch the opponent off guard.

If Isshiki is sent to the ninja world, they will lose the initiative.

During the Fourth Shinobi World War alone, the battle against Madara Uchiha caused immense destruction. And if the subsequent battle with Kaguya hadn't taken place in the Origin Sphere, more than half of the Shinobi World's landmass would probably have been destroyed by the aftershocks of the battle.

If Isshiki goes to the ninja world, Naruto and Sasuke will not be able to unleash their true power.

If a battle between Six Paths level fighters were to break out in the ninja world, it would likely shatter the entire ninja continent, resulting in countless deaths and injuries.

As for going to the alternate dimension where Isshiki is, that's a different story. It may seem like Isshiki's home turf, but in reality, Naruto and Sasuke can go all out without any worries here.

"That direction?" Sasuke activated his Rinnegan, and his powerful eye power began to circulate. A surge of violent chakra erupted from his body, and the purple chakra quickly materialized on his skin.

Soon, the complete Susanoo, which was over 300 meters tall, spread its wings in the sky.

Sasuke's body is located within the diamond-shaped crystal on Susanoo's forehead, controlling Susanoo to nock and shoot arrows.

The arrow, a symbol of destruction, quickly took shape.

Whoosh!

A streak of purple light ripped through space and sped toward the temple ahead.

Naruto gathered his chakra on the sidelines, preparing for battle.

Although Sasuke's arrow was incredibly powerful, it was much weaker than the final battle at the Valley of the End. After all, Sasuke at that time still possessed the power of the Six Paths Yin and had absorbed the chakra of eight and a half tailed beasts.

Isshiki's strength is comparable to Kaguya's, and even in his weakened state, he is still stronger than the two of them were back then.

boom!

With a deafening explosion, amidst the flames and smoke, the entire Ōtsutsuki Shrine vanished, leaving behind a massive crater, and the entire earth began to tremble violently.

Naruto and Sasuke looked up at the sky at the same time. Suddenly, Isshiki appeared above Susanoo. His figure flashed, as if he had teleported, and he appeared above Susanoo, less than ten meters away from the diamond-shaped crystal.

"So fast!"

Sasuke was startled and immediately controlled Susanoo to unleash a punch at Yishi, the violent force stirring up the clouds in the sky.

Among the Otsutsuki clan members they have encountered so far, Momoshiki and Kinshiki are the fastest. Momoshiki, in particular, has shown great taijutsu skills after consuming the chakra fruit that Kinshiki transformed into, but he is far less impressive than Isshiki.

boom!

Susanoo threw a punch, but the attack suddenly vanished into thin air.

next second.

Sasuke felt his entire Susanoo suddenly tremble violently.

Click!

A crisp sound came from the complete Susanoo.

"How is this possible?!"

With a violent tremor in his body, Sasuke stared in disbelief at the cracks on the rhomboid crystal. The entire Susanoo began to be covered with dense cracks, spreading like a spider web all over his body.

With his physical skills, he almost managed to destroy Susanoo, which was enhanced by Sage Mode, with a single punch.

boom!

With another powerful strike, Sasuke's Susanoo was instantly shattered.

It's incredible that someone could defeat his complete Susanoo with just two punches from pure power; even Kaguya couldn't do that.
