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

But Naraku's methods were too advanced.

With his current level of understanding and the analysis of his divine sense, he finally managed to conquer the "Caged Bird".

It's worth mentioning that Konoha also contributed significantly to this.

Among the numerous materials he obtained from the secret rooms and laboratories of the Dark Army base were his research on the White Eye and the Caged Bird.

Moreover, this research data was written by Tobirama Senju.

Without mentioning what Tobirama Senju's purpose was.

In short, this information provided Naraku with valuable research directions and inspiration, saving him a lot of trouble on his path to solving the "Caged Bird" puzzle.

As for what happens after it's cracked.

Naraku certainly wouldn't be kind enough to help the Hyuga branch family members untangle themselves.

Just like the Hyuga branch family members who are now being used as test subjects.

Naraku merely modified the other party's "Caged Bird".

For example, changing the control method so that the new "caged bird" is controlled only by him, rendering the main family's original control method ineffective.

Secondly, he removed the part of the "Caged Bird" technique that restricted the opponent's eye power, allowing the opponent's Byakugan to achieve the same level of insight as the main family.

After all, he wasn't like the main Hyuga family members, who feared that the branch family members would grow up and turn against them.

Rather than suppressing them, he would prefer them to grow.

"I'm so kind-hearted!"

Thinking about his modifications to the "Caged Bird," Naraku sighed again.

you do not say.

Compared to the original "Caged Bird," the new "Caged Bird" is much friendlier.

Leaving aside the liberation of pupil power, let's just talk about control.

The original "caged bird" was controlled by a group of people.

Any random member of the Hyuga main family, even if they're a complete waste, could easily treat the Hyuga branch family members like dogs.

Now, the new "Caged Bird Sequence" is controlled solely by Naraku.

He wasn't as twisted as the Hyuga main family members; at most, he used the "Caged Bird" technique to make people submit to him.

The research on the new "Caged Bird" was successful, and Naraku immediately put it into practice.

Whether they were members of the Hyuga branch family or the Hyuga main family, all the Hyuga people he captured were placed in a new "Caged Bird" trap.

During this period, there were instances of resistance.

For example, members of the Hyuga main family.

She fiercely resisted when she learned that she was to be put in a "caged bird" situation.

the reason is simple.

Even the original "bird in a cage" has no way to be completely freed.

This means that once a member of the Hyuga main family is placed under the "Caged Bird Seal," they will forever bear this cursed seal from birth to death.

As for the members of the Hyuga branch family...

There were rebels, but they were a minority; most were compliant.

Perhaps the "Caged Bird" theme has penetrated too deeply into the hearts of the Hyuga branch family members.

When the new "Caged Bird" was set up, Naraku only used it once as a deterrent, and most of the Hyuga branch family members immediately became obedient.

To be precise, it should be numbness.

The members of the Hyuga branch family obey the main family like dogs; clearly, there is little family affection involved, but rather it stems from oppressive rule.

For those who branched out of the Hyuga family, not all, but most, they had long since become numb under the oppression of the "Caged Bird Separation."

Whether it's the main family or anyone else, whoever controls the "Caged Bird" is their master.

Even when they saw members of the main family being subjected to the same "caged bird" trap, many of them showed other emotions beyond their numbness.

For example, gloating.

With the control of the "Caged Bird," the Hyuga clan was tamed very smoothly.

A week later, the first batch of Hyuga personnel who had been tamed were released from prison.

Regarding the Hyuga clan's arrangements, Naraku maintained the clan's traditional lineage for propagation.

After all, only in this way can the inheritance of the Byakugan be ensured.

Mixed-race individuals are too unpredictable.

Before the Hyuga clan has multiplied to a certain extent, the clan's reproductive methods can better ensure that the Byakugan's inheritance will not go wrong.

Of course, the Hyuga clan in the Land of Stars doesn't receive the same treatment as they did in Konoha.

Apart from the fact that their residences are planned together, in other aspects, such as resources, they are on par with other Star Ninjas.

In addition, when Naraku handed over the management of the Hyuga clan to Nonou, Nonou didn't stand on ceremony and immediately made various arrangements for the Hyuga clan members.

Some were assigned to the perception unit, while others were assigned to the combat unit.

It can be said that no one in the Hyuga clan can live off others; they all have to rely on their own efforts to survive and thrive.

After settling matters concerning the Hyuga clan, Naraku resumed his research on the "Reaper Death Seal."

"Dead Demon Sealing Technique" is a forbidden technique from the Book of Sealing, originating from the Uzumaki clan's heritage.

This forbidden technique can summon the Grim Reaper, thereby sealing the souls of others.

Since discovering that demons and spirits like the Wraith could be refined to enhance one's cultivation, Naraku immediately set his sights on this most easily found death god.

With Naraku's current level of understanding, even though the "Dead Demon Seal" is an S-rank forbidden technique, learning it wouldn't be too difficult.

But Naraku had no intention of performing this forbidden technique himself.

After all, given the nature of this forbidden technique, summoning the Grim Reaper is essentially the same as having the Grim Reaper possess the caster.

Even for safety reasons, Naraku would not allow a Shinigami to possess him using such a summoning method.

So after much effort, he finally managed to capture a spy from Iwagakure (Hidden Stone Village) from the prison.

That's right, they were spies.

As the Star Kingdom grows stronger, how could other forces possibly remain indifferent?

Whether it was during the Star Ninja Village era or now in Star City, spies from various ninja villages often infiltrate the area.

However, these spies often couldn't escape Naraku's senses.

They are usually secretly captured and then controlled by Naraku who sets up the "Seal of the Extinction of Tongue Calamity," thus developing into counter-espionage agents.

This is what happened to the Iwagakure spy captured from prison at that time.

However, this person had only recently been marked with the "Seal of the Root of Tongue Disaster" and had not yet been tamed into a counter-espionage agent.

Using illusion magic to control the spy from Iwagakure, Naraku did not immediately summon the Grim Reaper just in case. Instead, he used "Shrinking the Earth to an Inch" to take the spy away from Star City.

A short while later, Naraku appeared in a valley in the Land of Stars.

Releasing the Iwagakure spy who was gripping his shoulder, Naraku sensed his surroundings and, after confirming that there was no one else inside or outside the valley, stepped back a little.

"Shadow Imitation Technique: Shadow Puppet!"

With his palms clasped together, Naraku's shadow seemed to come alive, swaying and rapidly extending towards the Iwagakure spy opposite him.

The shadows of the two connected, but this was not the end.

Naraku's shadow climbed directly onto the body of the Iwagakure spy, then invaded his body, spreading throughout his entire body as if taking root and sprouting.

During this process, the Iwagakure spy's body trembled slightly, and then he raised his hands in front of him and began to form hand seals.

"The corpses are sealed away!"

As the hand seals were completed, chakra fluctuations surged from the Iwagakure spy's body, and the next second, a huge, illusory figure emerged from behind him.

This enormous, illusory figure was dressed in white robes, had a blue face and fangs, two horns on its head, and a full head of white hair.

This is the Grim Reaper summoned by the "Dead Demon Seal".

Chapter 167 Hunting Death

Learning the "Dead Demon Seal" was not difficult for Naraku.

What's remarkable is that he doesn't want to be the one to implement it.

So after this period of research, he finally came up with the idea of ​​using the Nara clan's shadow techniques.

"Shadow Puppet" is a technique he developed based on the shadow techniques of the Nara clan.

This technique allows one to use their own shadow to invade another's body, thus achieving puppet-like control.

Moreover, the level of control is extremely high.

Even a highly difficult forbidden technique like the "Dead Demon Sealing Technique" can be manipulated by others to perform under Naraku's control.
