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

Naraku's statement was highly appreciated by him.

It was only because he had noticed before that Naraku, like him, had been secretly glancing at Menchi's chest.

A figure even more powerful than he was at his peak.

A person I had never heard of before.

Such a person, regardless of their intentions toward the Dark Continent or anything else, undoubtedly deserves to be treated with utmost care.

Nitero's reaction was ignored.

Naraku found a room on the airship to rest.

I casually sat down on the sofa in the room.

A dark blue panel, visible only to Naraku, appeared before his eyes.

This panel is 'dark blue'.

That's right, he had already completed the development of his Nen ability before coming to find Netero.

The Nen ability is named 'Deep Blue Points'.

As a simple-minded Enhancement-type Nen user, Naraku believed that nothing was more suitable for him than the famous 'Deep Blue Points'.

Character: Naraku

[Lifespan: 97]

[Skills: Nameless Kung Fu Technique, Invisibility Technique, Lightning Strike Fist, Heavenly Eye, Illusion Technique, Entanglement, Absolute, Refinement, Circulation, Concealment, Condensation, Roundness, Firmness, Flow, Hardness]

【Attribute: 0.61】

Naraku opened the Deep Blue panel and looked directly at the attributes at the bottom.

The numerical value of the attribute represents the number of points that can be added.

In the development of 'Deep Blue Attribute Points', besides the loaded skills, the most crucial aspect is the acquisition of attribute points.

Naraku tried many methods in this regard.

For example, at first he tried to use pay-to-win methods.

Unfortunately, this attempt was unsuccessful.

Please add this to your favorites, recommend it, and vote with your monthly tickets!

Chapter 348 Deep Blue! Add Points!

Nen abilities largely follow the rule of equivalent exchange.

Paying money alone would greatly diminish the potential of 'Deep Blue Points'.

For example, high-end skills such as nameless martial arts and supernatural powers cannot be loaded onto the Deep Blue panel.

Therefore, after many attempts, Naraku finally found that there were only two ways to obtain attribute points.

The first channel is spending money.

At the cost of one's own lifespan, one year of lifespan can be converted into 1 attribute point.

The second way is to level up by defeating monsters.

By fighting and defeating enemies, you can obtain corresponding attribute points. In addition, you only have one chance to obtain attribute points from each enemy.

The 0.61 currently displayed comes from the second channel, contributed by Sisso and Nitero respectively.

Hisoka contributed 0.13 of that.

Nitero contributed 0.48.

Such a contribution is undoubtedly small compared to the life-saving efforts of the primary channel.

But that's how the Deep Blue panel makes its judgment.

Even if Netero and Hisoka were combined, they wouldn't equal Naraku's lifespan of one year.

Well, actually, comparing the strengths of both sides, they are about the same.

Even Netero.

There is a huge gap between him and Naraku.

Naraku's lifespan of one year is clearly far beyond what an ordinary person's lifespan can be compared to.

After determining the attribute points to be gained, Naraku once again used his consciousness to unlock the "Nameless Technique".

Whether it's the "Nameless Technique" or something else, each item in the skills section has a hidden mini-interface.

[Cultivation Technique: Nameless Technique - Qi Refining Perfection 0%]

When Naraku's consciousness unfolded the small interface of the "Nameless Technique," in addition to displaying more detailed cultivation levels, there was also a percentage-based energy bar.

This percentage energy bar represents progress.

Qi Refining Perfection 0% means that if the energy bar could be increased to 100%, then Naraku's cultivation could break through to the Foundation Establishment stage.

"Let me see your limits, Deep Blue skill points!"

The declaration was full of ritual. The next second, Naraku decisively invested all 0.61 attribute points he had gained into the 'Nameless Technique'.

The interface refreshed.

[Cultivation Technique: Nameless Technique - Qi Refining Perfection 6.1%]

Naraku stroked his chin as he gazed at the newly displayed data.

"So, according to the 'Deep Blue Skill Points' assessment, with my current cultivation progress, it would take me ten years to break through to the Foundation Establishment stage if I cultivate normally."

The development of Nen abilities is actually very mysterious.

But one thing is certain: the manifestation of Nen ability is closely related to the user.

Sometimes, Nen abilities can manifest aspects that are imperceptible to oneself.

For example, the current 'Dark Blue Points'.

Although the main body has experience in breaking through the Foundation Establishment stage, the main body's breakthrough was not achieved through hard work, but through the help of resources.

Now, through the presentation of 'Deep Blue Points', Naraku immediately and accurately grasped the distance between himself and the Foundation Establishment stage.

ten years.

This is the time it took him to break through the Foundation Establishment stage through his own arduous cultivation.

Well, ten years is the minimum.

Even with prior experience, Naraku couldn't guarantee a 100% success rate in breaking through to a higher realm.

The decade presented by 'Deep Blue Add-on' is merely a manifestation of this single thought's power.

In other words, the 'Deep Blue Points' skill allows him to break through to the Foundation Establishment stage with a 100% success rate, even at the cost of ten years of his lifespan.

These are the rules given by 'Deep Blue Points'.

"Great, it seems the development of 'Dark Blue Points' is perfect."

Ten years—no, exchanging 10 attribute points for a 100% chance of breaking through to the Foundation Establishment stage—was, in Naraku's view, well worth it.

He expressed great satisfaction with the 'Deep Blue Additions' he developed.

With this ability, his future need for resources will be greatly reduced.

When it returns to its original form in the future, it will bring great convenience to the original form.

"Oh right, I almost forgot to load the mental power."

Just as Naraku was about to close the Deep Blue panel, he suddenly slapped his forehead, chuckled, and began loading the mental power he had recently comprehended.

The power of the mind is the core power of thought, but it is not only reflected in thought.

For example, true qi.

Naraku secretly tried to infuse his spiritual power into his true energy, and found that in addition to the increased power, the true energy was also more flexible and controllable.

Such a discovery undoubtedly highlights the value of the power of the mind.

Loading went smoothly.

A moment later, the dark blue panel refreshed.

The skill levels are determined by Naraku.

To facilitate planning, he drew inspiration from supernatural powers.
