As Ghidorah roared toward the heavens, countless monsters of every race were forced to gather once more beneath the emperor's oppressive aura.
When they saw that the other two kings had also been "resurrected," excitement surged through the beasts. Their wariness finally faded, and they rushed into Brook's barrier one after another.
Seeing so many native mythical beasts step into the trap, Brook grinned.
This monster king was still somewhat useful.
As more and more native mythical beasts gathered, the sky gradually darkened.
At first, Brook had planned to use Sage Art: Lightning Release to stun them all and take them away. But when he saw the moon hanging over this world, he suddenly felt the urge to use that forbidden technique.
"Divine Art: Infinite Tsukuyomi!"
Brook's nine-tomoe red Rinnegan was projected onto the moon. A strange power poured down through the moonlight and pierced into the eyes of countless monsters.
Their eyes went dull.
And it was not only the monsters inside the barrier. Even monsters in distant regions began falling into illusionary dreams one after another.
"This power seems a little too strong."
Brook noticed that even the three-headed dragon, Ghidorah, had been affected.
It seemed the level of his Infinite Tsukuyomi was even higher than the Kotoamatsukami of his Rinnegan.
"Holy crap! I think I found a shortcut. If I combine Infinite Tsukuyomi with Divine Tree World Advent, won't I be able to absorb energy even faster?"
Brook suddenly recalled the Divine Tree in that state. It could accelerate the formation of new Chakra Fruits after absorbing chakra.
"Divine Tree World Advent!"
Excited, Brook immediately activated the forbidden technique. Countless roots and branches surged out, quickly binding the native mythical beasts.
But soon, Brook realized something was wrong.
Things were not going as he had imagined.
"Damn it! It still doesn't work! This forbidden technique recycles chakra energy, but the energy inside these monsters isn't chakra at all."
Brook cursed under his breath.
"As expected. Only when the Ten-Tails is in its Divine Tree state can it convert all kinds of planetary energy into the chakra energy needed by the Otsutsuki clan."
He sighed.
"Well, since they're already tied up, they can just go to prison inside their dreams."
Brook bound all the native mythical beasts inside the barrier and threw them into a designated prison space within [Kichijoten], planning to study them later.
He also killed some monsters and threw them into [Benzaiten], letting that space slowly extract their energy.
After several busy days, Brook finally captured every native mythical beast that had gathered nearby.
In the end, because these beasts were too scattered and their numbers were not concentrated, he wasted quite a bit of time.
He simply released [Infinite Tsukuyomi] and [Divine Tree World Advent], freeing all the native mythical beasts still outside his grasp.
"Ghidorah, your mission now is to gather every powerful monster under your command. The next time I return, I hope you won't disappoint me."
Brook left behind the three-headed dragon, Ghidorah, and the two monster king puppets, Godzilla and Kong. After assigning their mission, he departed from this world.
A black portal opened. Brook stepped through it and quickly left the primitive world, returning first to the ruins of the Northern Underworld, then back to the Naruto world.
At that moment, Otsutsuki Koshiki still had no idea that they had lost five Otsutsuki clan members all at once. The elder responsible for assigning the Otsutsuki team had not noticed anything unusual either.
After all, only a few days had passed since the mission began. There was no reason for information to return so quickly.
Brook returned to the Palace of the Rabbit Goddess with a smile on his face.
"My husband!"
The instant Princess Kaguya sensed Brook's aura, she rushed over through Yomotsu Hirasaka and threw herself straight into his arms.
"Haha! I came back with a great harvest!"
Brook held Kaguya with one arm while taking out a box from another dimension with the other.
"This is?"
Princess Kaguya had no idea what was inside the box covered in sealing runes.
"A complete Ten-Tailed Divine Tree."
Brook smiled and opened a corner of the seal.
A fierce roar immediately erupted from inside, followed by a massive surge of chakra.
"Husband, did you go to another planet?"
Princess Kaguya cried out in shock.
"You know that the Otsutsuki Origin Star usually only raises juvenile Ten-Tails. A fully grown Ten-Tailed Divine Tree usually only appears on a target planet."
"Not bad. This time, I not only stole a Chakra Fruit, I also took down several Otsutsuki."
Brook smiled and handed Kaguya three more Byakugan.
These eyes no longer improved Brook much, but they were extremely useful to Kaguya.
Besides, Brook had already absorbed superior Rinnegans. These Byakugan were only scraps he did not care much about.
Of course, he would never say something that offensive out loud.
"Thank you, my husband!"
Princess Kaguya was so moved that she could barely speak.
At that moment, she wished she could have several more children with Brook immediately.
This high-quality Ten-Tailed Divine Tree, along with the three Byakugan, was enough to help her enter her second evolution.
Perhaps she could even advance to the golden Rinnegan. Even if it was only the most basic golden Rinnegan without tomoe, it would still place her at the level of an elite Otsutsuki.
Her nine-tomoe red Rinnegan had already reached the peak of the first stage. It was only because she had eaten the high-quality Chakra Fruit of the Naruto planet that she had made such a great leap.
That fruit had transformed her from a low-level Byakugan guardian into a nine-tomoe Rinnegan user.
"I hope you can successfully advance and become the owner of a golden Rinnegan."
Brook laughed.
After devouring so many members of the Otsutsuki clan, he already understood the Byakugan's path of evolution.
Momoshiki's red Rinnegan could only barely enter the golden Rinnegan state after he ate the Chakra Fruit formed from Kinshiki.
Urashiki also needed to absorb the power of his blue Rinnegan and the red fish basket before his six-tomoe red Rinnegan could enter the golden Rinnegan state, greatly increasing both his strength and speed.
"I'll do my best. But my husband's nine-tomoe golden Rinnegans are still the most captivating."
Princess Kaguya stroked Brook's face, gazing at his three nine-tomoe Rinnegans in fascination, as if she were staring at a noble royal bloodline.
If advancing to the golden Rinnegan meant stepping into the elite class of the Otsutsuki, then owning a pair of nine-tomoe golden Rinnegans meant standing as the strongest elite beneath the elders.
Even the strongest descendants of the elders were only at that level.
Brook was already comparable to an Otsutsuki elder.
However, the golden Rinnegan was still not the end of the Rinnegan's evolution.
---------
According to legend, the Rinnegan on Otsutsuki Shibai's forehead had returned to its origin, becoming the most primitive white Rinnegan.
His two eyes were said to be a fusion of pure Byakugan and powerful spacetime divine eyes.
Legend claimed that he could materialize anything and turn thoughts into reality. It was the power gods used to create worlds, an ultimate authority only true gods could control.
Brook had seen all these legends in Kenshiki Otsutsuki's memories, so he did not know whether they were true.
However, one thing was certain. The five Otsutsuki elders all possessed golden Rinnegans with multiple tomoe on their foreheads.
The Rinnegan on the forehead was the hardest to advance. Even Brook's current forehead eye had only reached the level of a nine-tomoe red Rinnegan.
Of course, Brook could also imitate Urashiki Otsutsuki and absorb the power of a pair of nine-tomoe golden Rinnegans to forcefully advance the Rinnegan on his forehead.
With one forced evolution, the nine-tomoe red Rinnegan on his forehead might be upgraded into a six-tomoe golden Rinnegan, or even a nine-tomoe golden Rinnegan.
However, this kind of forced evolution had a time limit. It also came at the cost of sacrificing certain abilities and eye power.
Among the five Otsutsuki elders, several had chosen to imitate Otsutsuki Shibai. They retained one Byakugan, developed one special ability eye, then poured everything into nurturing the Rinnegan on their forehead.
One elder's forehead Rinnegan had already reached the level of a nine-tomoe golden Rinnegan, and both of his eye techniques possessed terrifying offensive power.
He was extremely powerful.
Kenshiki Otsutsuki was different.
He had forcibly developed his nine-tomoe golden Rinnegan through the special eye techniques [Benzaiten] and [Kichijoten], along with the full support of his father, Elder Ken. He was not famous for combat ability.
Through those two special eye techniques, he continuously fed power back to his father, helping Elder Ken become the strongest of the Otsutsuki elders.
That was the real reason Elder Ken doted on his youngest son so much.
Elder Ken walked the same path as Brook. First, he evolved both eyes into nine-tomoe golden Rinnegans. After that, he slowly nurtured the Rinnegan on his forehead.
At present, Elder Ken dominated the Five Elders with his pair of nine-tomoe golden Rinnegans and the six-tomoe golden Rinnegan on his forehead.
According to young Kenshiki's memories, Elder Ken's eye techniques also possessed terrifying offensive power.
Most importantly, if Elder Ken was willing, he could sacrifice the power of his two nine-tomoe golden Rinnegans and allow the six-tomoe golden Rinnegan on his forehead to briefly enter the legendary white Rinnegan state, obtaining divine power.
That was Elder Ken at his strongest.
However, the five elders had not fought in front of the younger generation for many years. Even young Kenshiki did not know what killing techniques the elders possessed. He did not even know his own father's special eye techniques.
All he knew was that another elder had a good relationship with Elder Ken. After that elder's forehead golden Rinnegan reached six tomoe, he gave up imitating Otsutsuki Shibai and evolved both of his eyes into Rinnegans as well.
Now, that elder possessed three six-tomoe golden Rinnegans.
This evolutionary path seemed weaker at first glance, but its combat power was no worse than an elder with a nine-tomoe golden Rinnegan on the forehead.
After all, the five elders had received roughly the same amount of Chakra Fruit nourishment. Their overall strength would not differ too much.
Different combinations of eye techniques could produce completely different combat power.
Only Elder Ken, because of his son Kenshiki's special eye techniques, had received an extra massive supply of chakra, allowing him to evolve faster than the others.
The current situation of the Otsutsuki clan was simple. Three elders formed an alliance against Elder Ken and his allied elder, barely maintaining balance.
However, after young Kenshiki was ambushed by Brook and disappeared, the Otsutsuki clan was now filled with hidden conflicts.
Elder Ken, in particular, had become a powder keg, ready to explode at any moment.
Originally, with his son's [Benzaiten] and [Kichijoten], Elder Kenshiki would sooner or later surpass the other elders by force and become the new patriarch of the Otsutsuki clan.
At that point, he could forcefully seize the entire Chakra Fruit supply and eventually become the new Otsutsuki God, just like Otsutsuki Shibai.
But now that he had lost Kenshiki, everything had to be built up slowly again.
He simply could not tolerate that.
If he had been strong enough to overwhelm the other three elders, Ken would have killed them long ago and monopolized all the resources of the Otsutsuki clan.
Unfortunately, his allied elder was unreliable. That old fellow only wanted to maintain the current peaceful status quo.
If Ken insisted that his ally hold off one elder while he tried to eliminate the other two, that ally would definitely refuse. He might even switch sides.
This infuriated Elder Ken.
That ally was utterly useless, yet Ken could not force him too far.
Ken was still investigating his son's disappearance with everything he had. He could not lose that resource.
If things continued like this, it would take him several thousand more years before the six-tomoe golden Rinnegan on his forehead could advance to nine tomoe.
As for evolving into a white Rinnegan, that was even further away.
One week later.
Palace of the Rabbit Goddess.
A massive aura spread across Mount Kaguya.
Kaguya had finally devoured the Ten-Tailed Divine Tree and the three Otsutsuki Byakugan. With that, she barely managed to upgrade the nine-tomoe red Rinnegan on her forehead into a golden Rinnegan.
Although this new eye did not have a single tomoe, it still allowed Kaguya to undergo a leap in life level, reaching the elite class of the Otsutsuki clan.
Brook had already absorbed the power of Otsutsuki Koshiki and Momoshiki, then refined and fused the powers of Kyoshiki and Urashiki.
Both Momoshiki and Urashiki had been able to reach the level of the golden Rinnegan. After Brook absorbed them, the nine-tomoe red Rinnegan on his forehead finally completed its evolution and advanced into a three-tomoe golden Rinnegan.
However, Brook felt that the mutated scarlet Chakra Fruit had helped him the most.
The level of that mutated Chakra Fruit was extremely high. It made Brook truly want to conquer that planet and plant a Divine Tree there.
"Husband, I feel that your aura has already reached the level of an Otsutsuki elder!"
Princess Kaguya became more and more infatuated with Brook.
She felt as though all her luck had been spent on meeting such a wonderful man.
This man must have been the world's way of compensating her for being sealed away for more than a thousand years.
"Not enough. I'm probably still not strong enough to deal with even the weakest Otsutsuki elder."
Brook spoke softly.
Based on Kenshiki Otsutsuki's memories, he did not dare underestimate those Otsutsuki elders.
He could already deduce their ultimate trump card.
If the elders were on the Otsutsuki Origin Star, they could devour other members of their own clan and continuously strengthen themselves.
If Brook judged them only by their apparent strength, he might end up walking straight into a furnace.
However, if Brook could lure the weakest elder to another planet, he might have a chance to hunt him down.
And that primitive planet seemed like the perfect battlefield.
Thinking of this, Brook could not help but smile.
Because the elder who had assigned the mission to Momoshiki and his group was the weakest elder in Kenshiki's memories.
For Brook, this was truly a stroke of luck.
