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

He looked at the dying Otsutsuki Kazuma, and without any hesitation, bent down and grabbed the other's head to probe his memories.

Kazuma Otsutsuki sensed the mental power invading his mind and immediately struggled fiercely.

Chapter 286 Preparation! Breakthrough!

"what!!!"

After a brief confrontation, Kazuma Otsutsuki let out a piercing scream.

Even with the power of the giant Tenseigan, he was still unable to resist Naraku's mental invasion.

Even because of her resistance, Naraku violently tore through her mental defenses.

This situation directly led to the fact that even if Kazuma Otsutsuki didn't die, he would become an idiot.

"I see, no wonder they trespassed on my territory," Naraku said thoughtfully.

Having successfully probed into the other person's memories, he immediately knew why the other person had appeared in Star City.

They even learned about the situation on the moon.

Naraku pondered.

He was naturally very interested in the Reincarnation Eye.

This applies to both the giant Tenseigan formed by the fusion of numerous Byakugan and the Tenseigan that Otsutsuki Toneri will awaken on his own in the future.

Based on the original storyline, Ōtsutsuki Hagoromo's younger brother, Ōtsutsuki Hamura, is also suspected to be on the moon.

Even if in the original story the other party was just a frail, elderly soul who only made a brief appearance before disappearing without a trace.

But who can guarantee that the other party isn't hiding behind the scenes like Hagoromo Otsutsuki?

If he rashly goes to the moon to seize the giant Tenseigan, Otsutsuki Hamura might jump out, or even draw out Otsutsuki Hagoromo.

"It's better to be cautious."

After thinking it over, Naraku decided to remain still for the time being.

He is now only one step away from the Foundation Establishment stage.

No matter how precious the Reincarnation Eye is, it's not as important as improving one's cultivation level.

His gaze fell upon Otsutsuki Kazuma, who looked dazed and confused.

"It's not a complete loss; at least we got a decent test subject!" Naraku's face showed a playful expression.

Compared to the Hyuga clan in the ninja world, this lineage on the moon is clearly closer to the Otsutsuki clan in terms of its appearance.

In order to acquire more resources for cultivation, his future expansion into the universe is inevitable.

This will inevitably lead to conflict with the Otsutsuki clan.

The Otsutsuki Kazuma before him was undoubtedly a perfect test subject for him to explore the bodies of the Otsutsuki clan.

Because the battlefield was in the desolate desert of the Land of Wind, the battle between Naraku and Kazuma Otsutsuki remained unknown to outsiders.

Having dealt with Otsutsuki and Shin, Naraku resumed his search for demons and gods.

The ninja world, however, continued to function as usual.

Apart from the occasional small-scale clashes between the Land of Stars, Iwagakure, and Kirigakure, nothing else major happened in the days that followed.

A month later.

In the Land of Wind, a demon made of sand was discovered in some ruins.

Three months later.

Naraku found a demon god resembling a mountain goblin in a mountain in the Land of Lightning.

Six months later.

Time always slips away quietly.

Before we knew it, a year had passed since we started searching for ghosts and spirits.

Yaoguang Hall.

"Kaguya Otsutsuki went to far too much trouble in her extermination of the demons and gods back then. I had to search the entire ninja world and only found five demons and gods."

Sitting cross-legged on the cushion, Naraku looked helplessly at the six crystals of demonic power placed in front of him.

Of these six powers of the spirits, one came from the evil god of the past, and the remaining five came from the harvest of this year.

Some are comparable to demons, while others are on par with death gods and evil spirits.

Naraku was naturally not satisfied with such a gain.

But this is already the limit.

Over the course of a year, he searched almost the entire ninja world. If there were any ghosts or gods he missed, he could only admire their ability to hide.

"Fortunately, although the search for ghosts and spirits was somewhat lacking, the other gains were still quite good."

Thinking about the other things he had gained during his search for ghosts and gods, Naraku's mood improved considerably.

There's a saying that goes, "Since we're already here," right?

He traveled all over the ninja world that year.

Besides searching for ghosts and gods, they also discovered many resources needed for cultivating immortality in the process.

For example, a miraculous medicine.

Although century-old medicinal herbs are rare, the ninja world is not entirely without the opportunity to produce them, so he still found some this year.

As for medicinal herbs that are decades old, there are even more of those.

He didn't waste these medicinal herbs; he transplanted them all into the medicinal field and continued to cultivate them using the Heavenly Divine Water.

In addition to the medicinal herbs that were originally cultivated.

After a year of cultivation, he has now refined over a thousand high-grade True Essence Pills.

"Thousands of True Essence Pills, plus these five Ghost God Power Crystals, and three Tailed Beasts—if this lineup still can't break through to the Foundation Establishment stage, then I'll accept it," Naraku thought fiercely.

That's right, Naraku is currently preparing to break through to the Foundation Establishment stage.

In addition to preparing True Essence Pills and Ghost God Power Crystals, there are also Tailed Beasts.

More than half a year ago, he found an opportunity to safely extract the three tailed beasts from the bodies of Nono, Natsumi, and Kushina.

Now, the four-tailed, five-tailed, and nine-tailed creatures have all been sealed inside the bronze tower by Naraku.

Lost the tailed beast.

The strength of Nono, Natsumi, and Kushina inevitably declined.

However, the three women themselves were not bad either.

Even without the tailed beasts, the three women's strength remained stable at the second stage of elite Jonin.

Not to mention, in order to compensate for the decline in the three women's strength, Naraku also made special improvements to the magical artifacts.

For example, Nono and Natsumi's [Silk Gloves] and [Peacock Armor] have both been successfully upgraded to mid-grade human-level magic weapons.

Kushina was the same; he also crafted a set of mid-grade human-level magic weapon armor for her.

As time went by, for Naraku, crafting a mid-grade human-level magic weapon was no longer difficult, as long as the materials met the requirements.

This is not only due to the steady improvement in weapon crafting techniques, but also thanks to the "Blazing Sun Technique".

The blazing fire condensed by the Blazing Sun Technique can be used not only in combat, but also in refining weapons and alchemy, where its effects far surpass those of true qi fire.

Especially when one achieves some success.

The effect is even more significant.

On another note.

After completing the unification of the five elements, Naraku has resumed his training in the Five Elements Techniques, with his primary focus being the "Blazing Sun Technique".

The purpose is precisely to assist in weapon crafting and alchemy.

Back to topic.

Naraku's preparations for the upcoming breakthrough were undeniably thorough.

Once everything was ready, he immediately activated the array set up in Yaoguang Palace.

It's a formation, not a barrier.

Because of the importance attached to the Foundation Establishment stage, Naraku added the study of formations to his studies of weapon crafting and alchemy during this period.

Although the array currently set up in Yaoguang Palace is not a particularly powerful array, its defensive capabilities are definitely superior to the barriers that are circulating in the ninja world.

This formation provides defense.

Naraku believed that even if he were to be ambushed by Hagoromo Otsutsuki during his breakthrough, he would be able to delay the opponent's movements, giving him more time to react.

Calm your mind and focus your attention.

Naraku, who was sitting cross-legged with his five hearts facing the sky, quickly entered a state of perfect harmony with his mind.
