I will use the ninja world to aid my cultivation of immortality.

This race is indeed the strongest race to dominate this universe.

Just like the ninja world, this clan cultivates divine trees and extensively searches for life-bearing planets in the universe, thereby absorbing the planets' essence to enhance their power.

"With my current strength, most members of this clan are no longer a threat. The only ones I really need to be wary of are the upper echelons," Naraku said with a deep look in his eyes.

Like ninjas, not every member of the Otsutsuki clan possesses Six Paths level strength; there are also differences in their abilities.

Although this clan possesses extraordinary talents and a rare treasure like the Divine Tree, the strength of its lower and middle-level members is only equivalent to that of elite Jonin at the third stage or below the Six Paths level.

Such strength would be formidable to others, but it would pose little danger to Naraku.

Chapter 309 The Original Hokage! Foundation Establishment Perfection!

As for the upper echelons...

The weaker ones are comparable to Otsutsuki Hamura, while the stronger ones are much stronger than Otsutsuki Hagoromo.

That's right.

Among the entire Otsutsuki clan, Hamura and Hagoromo are considered to be among the top in terms of strength.

Logically speaking, the Otsutsuki clan planted countless divine trees, while the ninja world only had one, so the difference in strength between the two sides should be enormous.

The reason for this situation actually stems from the ninja world.

The planet of the ninja world may seem ordinary, but in reality, its original planetary origins are among the most significant in the Otsutsuki clan's rich experience of cultivating the Divine Tree.

Therefore, even though the Divine Tree in the ninja world has not fully grown, the chakra fruit it produces is extraordinary, enough to allow the inheritor to easily enter the upper echelons of the Otsutsuki clan's fighting force.

Let's talk about the Otsutsuki clan.

Besides the upper echelons, according to Kaguya Otsutsuki's memories, this clan also has a being who is hailed as the closest to a god.

This near-god was also the key to the Ōtsutsuki clan's ability to dominate the entire universe, treating it as a nursery and planting divine trees at will.

However, because Kaguya Otsutsuki's status in the Otsutsuki clan was only average, the information about this near-god was relatively superficial, making it impossible for Naraku to fully assess her true strength.

"Based on the current situation, this world should not involve Boruto."

Having learned the details of the Otsutsuki clan, Naraku also confirmed another matter based on Kaguya Otsutsuki's memories.

Boruto is the sequel to Naruto.

However, there are clearly differences between the two.

Saying it's a case of adding a dog's tail to a sable coat might be disrespectful, but the situation is pretty much the same.

When Naraku was searching for demons and gods, he actually did some research in this area.

But nothing was found.

Only now, after reading Kaguya Otsutsuki's memories, has he truly grasped the situation of this world.

The Naruto world he inhabits should be the original version of "Naruto" and does not involve the subsequent Boruto.

After all, there is no such person as Otsutsuki Isshiki in Kaguya Otsutsuki's memories.

Naraku's gaze fell on Kaguya Otsutsuki in his hand.

"Fine, I'll spare your life!"

After some thought, Naraku decided not to refine Kaguya Otsutsuki along with her, but instead only extracted the essence of the Divine Tree from her body.

He doesn't deny that he's a hypocrite.

Kaguya Otsutsuki was still very attractive to him.

He wouldn't mind having a pet if the other party wasn't a threat.

With his right hand grasping, he pressed it against Kaguya Otsutsuki's abdomen, and as his magical power circulated, the essence of the Divine Tree was rapidly drawn out.

As the first person to master the Divine Tree, Kaguya Ōtsutsuki has primary authority over it.

Even if Hagoromo Otsutsuki becomes the Ten-Tails' Jinchūriki, if Kaguya Otsutsuki escapes, she can still take back the Ten-Tails immediately.

However, permissions are one thing.

In terms of origin, the Ten-Tails still accounts for the majority.

When the extraction was finished, the divine tree essence that Naraku obtained from Kaguya Otsutsuki was far less than that of the Ten-Tails.

Of course, this is in comparison to the Ten-Tails.

Compared to others, it is still quite remarkable.

Even the energy crystals refined by Hagoromo Otsutsuki were not much better.

"Just how bad must this woman's fighting ability be to lose so miserably!" Naraku couldn't help but mutter.

The remaining essence of the Divine Tree is close to that of Hagoromo Otsutsuki, who accumulated it over a thousand years. If the Ten-Tails is added, in terms of energy, Kaguya Otsutsuki would have had an overwhelming advantage when she fought her two sons.

Despite this advantage, the woman ultimately lost.

He really couldn't help but complain.

Although Kaguya Otsutsuki was left behind simply to be a pet, there are requirements for pets; it's not enough for them to just be pretty.

Naraku felt it would be very necessary for him to train Kaguya Otsutsuki in the future.

As a direct descendant of the Otsutsuki clan, the opponent's innate talent is definitely superior to that of everyone else in the ninja world.

With proper training, they can still be developed into outstanding combatants.

After putting Kaguya Otsutsuki back into the Bronze Tower, Naraku immediately began refining and absorbing the extracted essence of the Divine Tree.

Sit cross-legged.

Strands of the divine tree's essence entered his body.

As the nameless technique was activated, the refined divine tree essence immediately caused Naraku's magical power to surge once again.

A few days later.

Kaguya Otsutsuki's divine tree essence was completely absorbed.

Naraku finished his practice and opened his eyes.

"Not bad!" Naraku nodded slightly after sensing the progress of his cultivation.

The energy required for cultivation in the later stages of Foundation Establishment naturally increases significantly.

However, even after refining Kaguya Otsutsuki's divine tree essence, Naraku's cultivation level is still only about 30% of the late Foundation Establishment stage.

Naraku was already quite satisfied with this progress.

If it were a normal cultivation practice, even with the light of the sun, moon, and stars, it would still take many years of hard work to achieve the desired results through one's own arduous cultivation.

After a short rest, Naraku resumed his training.

The second thing absorbed was the energy crystal from the toad pill.

This energy crystal is far inferior to the original source of Kaguya Otsutsuki's Divine Tree.

It was absorbed in just one day.

The improvement in cultivation level was only a little over 40%, from 30% to a little over 40%.

Next was the energy crystal of Ōtsutsuki Hamura.

This energy crystal is almost identical to the energy crystal of the Toad Pill.

It was absorbed in just one day.

His cultivation level has advanced to approximately 60%.

Next, Naraku retrieved the energy crystal of Hagoromo Otsutsuki.

This energy crystal is second only to the Ten-Tailed Fox's energy crystal.

Under the absorption of the power, Naraku's cultivation level rose steadily.

Sixty percent, seventy percent, eighty percent, ninety percent, and ten percent.

When the energy crystal was completely absorbed, a sense of perfection naturally emanated from Naraku's body.

Slowly let out a breath.

Naraku opened his eyes.

"Danger and opportunity go hand in hand; this saying is indeed true." Naraku said with great emotion as he felt his cultivation advance to the peak of the Foundation Establishment stage.

The former Hagoromo Otsutsuki was a threat.

But once the threat is resolved, it becomes an opportunity.

If it weren't for the support of people like Hagoromo Otsutsuki, how could he have reached the pinnacle of cultivation so quickly after only stepping into the Foundation Establishment stage?

"Just to be on the safe side, let's make more preparations. And we can also use this time to strengthen our supernatural abilities."

After a moment of contemplation, Naraku did not take out the last Ten-Tails crystal to break through.

When it comes to breaking through to a higher level, you can never be too cautious.

His cultivation during the Foundation Establishment stage was incredibly fast.
