I'm in Konoha, and I have ten skill slots.

A perfectly good system was reduced to just the skill bar module that could barely function. If it's not fixed, even the last skill bar will be gone.

[Collecting data for active skills bar]

[Active Skill: Gluttony※]

[Effect: Extremely hot and burning...]

[Active Skill: ※※者]

[Effect: Extremely hot and burning sensation]

[Active Skill: Great Sage※]

[Effect: Extremely hot!]

Good grief, he's giving himself gibberish!

Is it possible to fix this?

[The active skill bar is currently undergoing maintenance; the maintenance time is unknown.]

Get out of my way!

The repair time is unknown, so it seems we don't even know when we'll be able to find out what these three active skills are!

What about the passive skill bar?

[Passive Skill: Empty]

[Passive Skill: Empty]

[Passive Skill: Empty]

……

[Passive Skill: Empty]

The skill bar is completely empty; there's nothing there.

The active skills are alright, at least there's a bunch of gibberish, but what the heck is this passive skill? It's completely gone?

[All passive skills have been detected as missing. The host can reinstall passive skills themselves.]

Install it yourself?

How do I install it, and what are the benefits of installing passive skills?

[Current host's skills: Chakra Refining Technique, School-level Physical Techniques, Shadow Clone Technique, Transformation Technique, Substitution Technique... Basic Kunai Throwing Technique, Basic Cooking, Basic Walking, Basic Jumping... Basic Language, Basic Mathematics, Basic Communication... Basic Eating, Basic Drinking...]

Shigure: ...

Is this person even considering eating and drinking as a skill?

Does wiping your butt count?

[Advanced Butt-Wiping Techniques]

roll!

Why is wiping your butt considered high-class? Because you're really good at wiping your own butt.

Shi Yu looked helpless. This remaining skill slot in the system seemed unreliable!

Maybe this is fate!

Shigure glanced at the Chakra Refining Technique, the first skill that the system had designated as a skill.

I clicked it casually and added it to the passive skill bar.

Passive skill successfully installed.

Does that mean it's installed?

Any functions!

[Current Passive Skill: Chakra Refining Technique]

[Effect: Combines physical and mental energy to refine chakra]

[Running]

Ok?

Running...?

Chapter 2: Overlapping Skill Effects Doubled

run?

It's already running?

Just put it in and start?

The purpose of chakra refining techniques is self-evident.

The second lesson at the Ninja Academy was about how to refine chakra.

Although everyone theoretically possesses chakra, ordinary people cannot refine it.

Only those with exceptional talent, that is, those with a certain talent in chakra, can combine physical energy and spiritual energy to refine chakra.

For six years, Shigure refined chakra day and night without interruption.

but!

With limited talent and aptitude, Shigure's current chakra level is only in the bottom tier within the Ninja Academy.

In terms of chakra reserves, he's still quite a ways off from meeting the requirements for a genin.

However, chakra extraction cannot be done 24 hours a day.

Both physical and mental energy need to be restored. Often, after a few refinements, it becomes impossible to continue and requires a certain amount of recovery time.

Different people, with different talents, can refine different qualities of chakra each day.

However, no matter how talented someone is, there are limits to how much physical and mental energy they can consume.

Once you reach your limit, you can no longer refine chakra.

Perhaps it's the body's self-protection mechanism; if you continue to forcibly extract chakra, you will faint and collapse.

In the end, not only did they fail to extract chakra, but their original chakra would also dissipate.

Shigure can now refine chakra three times a day, but he will faint and collapse after the fourth refinement.

The teachers at the ninja academy also explained that as people grow older, their bodies become stronger and their mental strength increases, which will lead to more frequent chakra refining.

The amount of chakra will also gradually increase.

But for people like Naruto from the Uzumaki clan, refining chakra is practically like having a cheat code.

It is conservatively estimated that even if it were Naruto's first time refining chakra, he could complete hundreds of refining processes in a single day.

This is the difference between geniuses and ordinary people.

It is simply insurmountable.

[Passive Skill: Chakra Refinement]

[Number of times completed]

When the sound rang out, Shi Yu was startled for a moment.

Suddenly, I felt a warm current slowly surging through my body.

Shigure was all too familiar with this feeling; he experienced it three times a day.

This is the feeling of completing chakra refinement and increasing chakra reserves.

Completing one refinement only increases chakra by a tiny bit.

The chakra flow within Shigure's body is currently only the size of a little finger; this is the chakra refined over six years.

Such a weak passive chakra level doesn't even meet the standard for a genin.

According to Shigure's own understanding, a genin's chakra reserves should be at least a size larger.

Only in this way can one barely reach the standard chakra level for a genin.

Carefully sensing the increase in chakra within his body, Shigure felt that even though it was only a trace of chakra, it seemed to have been refined perfectly.

This kind of chakra can only achieve its best effect when the Shigure state is full and one is wholeheartedly devoted to refining it.

This passive skill bar seems to have allowed Shigure to complete a chakra refinement in his best condition.

Furthermore, he doesn't need to control it himself, and after completing the chakra refinement, there is absolutely no consumption of physical or mental energy within his body.

This is……

'Increase chakra levels out of thin air?'
