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

Just as Shigure was surprised, his chakra increased by a little.

This time, Shigure showed a surprised expression.

'Another...another increase!'

In just about ten minutes, two chakra refinements were completed?

Is this the effect of the passive skill bar?

This is too perverted!

Not only can he refine chakra, but he also does so without any cost. If that's the case, doesn't it mean that he can refine chakra without any limit just by sitting there?

Every few minutes, every few minutes.

One hour is equivalent to several months of my past training!

Reaching the standard of a Genin doesn't seem too difficult!

With his eyes closed, Shigure carefully sensed the flow of chakra within his body, under the control of his passive skill bar.

Five minutes passed, and another sliver of chakra was added.

Shigure remained motionless, sitting on the bed with her eyes closed.

Half an hour passed in the blink of an eye.

The passive skill slot allowed Shigure to complete six chakra refinements.

Only now did Shigure slowly open her eyes.

ecstatic.

Shigure's limit for refining chakra each day is three times, but in this half hour, he has refined it six times.

I still don't feel tired at all, as if I haven't done anything.

However, the problem is that the amount of chakra has increased.

The chakra fluctuations within his body were noticeably stronger than before.

If I sit like this for a whole night, I'll probably reach the chakra standard for a genin.

Expanding the chakra within the body is absolutely no problem.

"Wait, no rush!"

We've been through more than a decade, so what's a little more time?

Shigure still has six skill slots left, so I need to pick out a few more skills and put them in!

Looking at his skills, Shigure decided to leave aside basic necessities like eating, drinking, and relieving himself, and instead select useful skills like ninjutsu to add to his repertoire.

However, when Yu was examining her skills...

Shigure was unsure what to choose, but when she saw the first skill among the available options was still Chakra Refining Technique!

Can I continue equipping the same skill?

With a try-it-out mentality, Shigure added yet another Chakra Refining Technique to his passive skill bar.

Passive skill successfully installed.

[Current Passive Skill: Chakra Refining Technique]

[Running]

It actually works!

[Passive skill, completed once]

The next second, two strands of chakra appeared simultaneously.

Double the effect?

Installing two passive skills of Chakra Refining Techniques directly grants double the training effect.

Shigure's eyes gleamed.

I was about to scream.

But I still held back.

'There are still five empty passive skill slots. If I install Chakra Refining Technique on them all…'

It has a direct seven-fold effect, operates once every five minutes, and is made from Shigure's chakra at its most perfect state.

Even Sasuke, who is hailed as a genius, or Naruto, who inherited the powerful physique of the Uzumaki clan, cannot reach this speed of chakra refining!

Shigure's chakra refining is completely energy-efficient, without causing fatigue or a decline in his condition.

Each refinement achieves the most perfect chakra refinement ever completed.

"Install the Chakra Refining Technique on all of them..."

With a wave of his hand, Shigure installed Chakra Refining Technique on all five empty passive skill slots.

Refining effect at its most perfect state

Chapter 3 Updates Skill Status

[Passive skill... Completed once]

……

[Passive skill... Completed once]

……

I was suddenly awakened by the rain in the early morning.

Looking at the familiar room, I was still lying in my own bed.

Oh no, when did I fall asleep?

How's the chakra refining going?

Summon the system directly with your thoughts.

Seeing that the skill bar was still there, Shigure finally breathed a sigh of relief.

Shigure was originally so excited that he wanted to sit there all night without sleeping, fearing that if he fell asleep, he would stop refining his chakra.

Or the system simply disappeared.

But now I'm relieved. It's not a dream. The system hasn't disappeared; it's still there!

"By the way, how's the chakra extraction going?"

[Passive skill... Completed once]

A sudden surge of chakra erupted within Shigure's body.

Shi Yu was stunned.

Feeling the astonishing flow of chakra within his body, which was more than twice as strong as before.

Shigure's chakra level has now fully met the requirements for a genin.

Not only did they meet the requirements for a Genin, they even exceeded them.

At this point, he should be considered to have reached the mid-stage of Genin.

The amount of chakra was doubled, and it was all refined from Shigure's most perfect chakra.

In terms of quality, it far surpasses the chakra that Shigure had previously refined and accumulated.

"I just slept for one night, and not only did my chakra level more than double, but the quality was also amazing!"

Looking at the word "Passive" displayed on the skill bar.

"Passive skill, passive skill, it doesn't require any control from me at all, it will activate no matter what I do!"

"So, whether I'm walking, running, or sleeping, it doesn't affect chakra refining!"

"If that's the case... then this system is absolutely amazing!"

Even if there's no shop module, task module, reward module... that doesn't matter.

These skill slots are more than enough.

Moreover, there are no restrictions whatsoever. You can put any skill into it, and it will continue to operate autonomously regardless of Shigure.

In this way, even eating and drinking will make you stronger.

Even if I never know what those three active skills are, I feel like having these passive skill slots is enough.

It's a pity there aren't enough passive skill slots. If only there were a hundred or a thousand!

Thinking about this, Shiyu felt that she had been a bit greedy.

Having a system at all is already quite good.

Suddenly, a warm current surged through his body, and his chakra level increased again.
