I use the ninja world to help me cultivate immortality

After being amazed, Naraku began to estimate his current strength.

Well. Take the two brothers Otsutsuki Hamura and Otsutsuki Hagoromo as a comparison.

Assume that Otsutsuki Hamura's strength is 1 unit.

Then Otsutsuki Hagoromo's strength is 2 units.

Without counting the bronze tower projection, when they fought, his strength was just in the middle, with 1.5 units.

Now, his strength has also reached 2 units.

Don't look at the fact that he has crossed the entire foundation-building initial stage and broke through to the foundation-building middle stage to increase by 0.5 units. When the strength reaches the foundation-building stage, even if it is 0.1 units, it is an extremely amazing distance.

Like Uchiha Madara.

In the state of the Impure World Reincarnation, his strength is at least 0.6~0.7 units.

But if it is placed in the 1.5~2 unit range, the opponent's entire person will only have about 0.1 unit of improvement space.

"We can't relax. We still have to continue to improve."

It is certainly gratifying to catch up with Otsutsuki Hagoromo at that time, but Naraku did not relax because of this.

His strength is improving, and Otsutsuki Hagoromo may not be the same.

Even if the opponent did not have a backup plan on the Ten-Tails Chakra as he thought, the seven tailed beasts and a pair of Samsara eyes cannot be faked.

With this alone, the opponent's strength is enough to go further.

Naraku looked at the mana clone guarding the side.

"Go and deal with Uchiha Obito and Black and White Zetsu."

"No problem!"

The mana clone gladly accepted the order of the original body and immediately activated the "space jump" to leave.

Watching the mana clone leave, Naraku leisurely took out Uchiha Madara's sealed body for refining.

When sealing Uchiha Madara's soul, he actually secretly activated "retracing the past".

Based on the past he retraced, he knew that the other party's resurrection was caused by Black and White Zetsu.

Now Nagato has been taken away by Otsutsuki Hagoromo.

He has no worries about dealing with characters like Uchiha Obito.

He ignored it because he was focused on the breakthrough before.

Now that the breakthrough is successful, the mana clone can move freely.

It only took a moment.

The mana clone that left moved back.

"Here!"

Seeing the mana clone return, Naraku, who was refining Uchiha Madara, stopped his action, and then saw the mana clone stepped forward and handed out an item from each hand.

In the left hand was a pair of Mangekyō Sharingan.

In the right hand was a gem-shaped seal.

Seeing the two items handed out by the mana clone, Naraku used his mana to take them in front of him.

Bang!

The mana clone was released, and the feedback information immediately let Naraku know his experience when he went out.

Uchiha Obito doesn't need to be mentioned.

This person is hiding in the Hidden Mist Village, and Naraku already knows it.

With the strength of the mana clone.

Even without counting the [Reincarnation Eye], it is completely stress-free to solve it.

As for Black and White Zetsu.

When Uchiha Madara came first, Black and White Zetsu did not follow.

Later, I don’t know whether they did not find that Uchiha Madara was captured by Naraku or had no other way to retreat, Black and White Zetsu returned to Uchiha Obito.

The result was that they were caught by the mana clone.

There is also a small episode.

That is, when being captured by the mana clone, Black Zetsu tried to escape.

Not to mention, although the strength of this little thing is far inferior to Otsutsuki Hagoromo and Otsutsuki Hamura, as a backup left by Otsutsuki Kaguya before sealing, the ability to escape is still very powerful.

Most of the time the mana clone spent on going out was spent on capturing Black Zetsu.

Let’s talk about the two items brought back by the mana clone.

Among them, the Mangekyō Sharingan came from Uchiha Obito.

The other sealed body is Black Zetsu.

After understanding the process, Naraku split another mana clone and let it continue to hold the [Rinnegan] as a guard.

"These eyes are left to you to refine!"

Naraku controlled the mana and handed the Mangekyō Sharingan to the mana clone.

"Okay!" The mana clone shrugged.

After taking the Mangekyō Sharingan, he began to refine it.

Naraku looked at the remaining sealed body of Black Zetsu.

The divine sense explored, and the situation of Black Zetsu quickly fell into perception.

"Although the strength of Kaguya's third son is not worthy of the name, his identity is still in line with it." Naraku nodded slightly.

Just as the mana clone would specifically bring Black Zetsu back.

In the exploration of the divine sense, Naraku can sense that Black Zetsu's body contains energy that is in the same vein as the core of the tailed beast's origin.

Although this energy is not particularly huge, its nature is undoubtedly also from the Ten Tails, or the Divine Tree.

There is a gain, but not much.

This is Naraku's evaluation of Black Zetsu.

The power of the sacred tree contained in the opponent is not as good as that of the four-tailed and five-tailed.

However, no matter how small a mosquito is, it is still meat.

It is better to have it than not to have it.

Put the Black Zetsu sealed body into the bronze tower.

Naraku is ready to wait until Uchiha Madara is refined before the opponent's turn.

The Nine-tailed is placed last.

Crack!

I don't know how long it has passed.

The sealed body in the palm suddenly shattered and dissipated.

Huh~

Naraku slowly exhaled a foul breath.

The cultivation level broke through the middle stage of foundation building, and the speed of refining also increased.

The shattering of the sealed body was due to the thorough refining of Uchiha Madara's chakra soul.

As the new stage of refining ended, Naraku silently felt the progress of the improvement of mana.

The same speed as refining.

The energy required for the middle stage of foundation building is still higher than that for the early stage of foundation building.

Uchiha Madara, whose comprehensiveness is comparable to the four-tailed and five-tailed, only allowed Naraku to go three-tenths of the way in the middle stage of foundation building.

"Continue!"

After a brief pause, Naraku took out the sealed body of Black Zetsu.

Continue to refine.

The power of the sacred tree contained in Black Zetsu was extracted bit by bit, allowing Naraku to improve rapidly again.

More than half a day's work.

Black Zetsu's sealed body also shattered and dissipated.

Correspondingly, Naraku's cultivation reached four-tenths in the middle stage of foundation building.

"Now only the last Nine-tailed is left!"

Taking the sealed body of the Nine-tailed from the bronze tower, Naraku took a look with a burning gaze and decisively began to refine.

Boom!!!

As soon as the refining began, the strong tailed beast origin poured into Naraku's body.

The Nine-tailed is worthy of being the Nine-tailed.

The hugeness of the origin far exceeds the Four-tailed and Five-tailed.

As he refined, Naraku's cultivation rapidly impacted the perfection of the middle stage of foundation building.

Day after day.

Starting from the refining of the Nine-Tailed Fox, the time came to the third day.

Suddenly, a perfect breath emanated from Naraku's body from the inside out.

"The middle stage of foundation building is perfect."

Naraku slowly opened his eyes, and the mana inadvertently overflowed, and his eyes turned into a substantial divine light, almost piercing through the opposite palace wall.

Converging the surging mana, Naraku looked down at the sealed body in his hand.

From four-tenths to perfection, the sealed body of the Nine-Tailed Fox actually still had half.

More importantly, the origin core of the Nine-Tailed Fox was still intact.
