Naruto: I have Ten Skill Bars

They returned to the same forest where Gekkō Hayate had brought Shigure last time.

By now, the sky had turned completely dark.

The area around them was deathly quiet—no insects chirping, no wind rustling the leaves. It was the perfect place to concentrate on chakra fusion training.

"Let's begin."

One night should be enough, or so Shigure thought. But as soon as he got started, reality hit him hard.

Why were Kekkei Genkai—Bloodline Limits—so admired by ninja everywhere?

Because developing one wasn't just difficult… it was borderline insane.

Boom!!

Boom!!!

Boom!!!!

Every ten minutes or so, the silence of the forest shattered with a sharp explosion.

After the incident where he nearly burned down a building, Shigure had become extremely cautious. Now, he only generated minuscule amounts of fire-nature and another elemental chakra simultaneously.

At such small levels, either chakra alone was harmless. But the moment he tried to fuse them?

The resulting blast gave him a splitting headache—literally.

He triggered explosion after explosion. Dozens of them. His hands were covered in small cuts and burns, but nothing serious. He had at least mastered the art of barely avoiding self-destruction.

Unfortunately, his clothes weren't so lucky. The violent chakra tore them to shreds.

Despite carefully adjusting his chakra control after each attempt, the outcome was always the same.

No progress. None.

"It's still not working…"

"Not even the tiniest improvement!"

The two chakra types exploded the instant they touched. Fusion? He couldn't even get them close without needing a new set of clothes.

Shigure flopped back onto the grass, arms spread wide, staring up at the moon.

"How the hell are you supposed to fuse two types of chakra?"

The rain had started earlier—around six or seven in the evening—and it was still drizzling into the night. Cold droplets ran down his cheeks as he lay there, soaked and exhausted.

Still no progress.

Shigure sighed. "Yeah... Maybe developing a bloodline limit overnight was just a bit too optimistic."

Looking back, his confidence now felt naive. No wonder Bloodline Limits were so coveted by the great ninja villages. Unless you were born with one due to some rare genetic quirk or accident of nature, trying to create one later in life was like trying to climb to the moon.

Sure, there was another route—just capture a Tailed Beast and learn from it. Didn't the Sand Village learn Magnet Release from Shukaku?

If he wanted to master Boil Release, did that mean he had to hunt down the Five-Tails?

"Chakra fusion shouldn't be this hard…"

It didn't feel like the kind of fusion he'd read about in chakra theory. Something was off.

[Great Sage※: Reminder – The host's fire-nature chakra may not be strong enough.]

Fire-nature chakra not strong enough?

What did that even mean?

"I've already mastered two nature transformations. Isn't that enough? Or is it that I don't have enough chakra?"

[Great Sage※: For example, if your water-nature chakra is at 10% strength and your fire-nature chakra is at 20%, you won't achieve balance. Chakra fusion requires proportional strength. Mastering nature transformation doesn't fix the power output.]

"…Wait, seriously?"

Shigure sat up and started thinking more critically.

So mastering a chakra nature just lets you use it—but it doesn't mean its power is fixed. That power can be raised further, independently.

Which means...

Right now, his chakra nature strengths were too imbalanced. No matter how hard he tried to merge them, he wasn't even meeting the minimum threshold.

No wonder he kept exploding.

"To successfully develop a Kekkei Genkai, the strength of both chakra types has to reach a certain level first!"

Just like in the example—20% fire-nature and 10% water-nature… If the output is uneven, the result is chaos. Fusion requires balance, but achieving that doesn't mean a perfect 50-50 split.

'I get it now…'

Even other known bloodline limits follow this principle. Though they all involve fusion, one element always dominates slightly. Perfect equality is a myth—what matters is stability, not symmetry.

Like comparing a pound of cotton and a pound of iron—same weight, vastly different volumes.

"So right now, I need to increase the power of my fire-nature chakra?"

[Great Sage※: That may be advisable.]

Shigure sighed.

"Well… thanks for the maybe, I guess."

But… it might still work!

"How exactly do I increase my elemental chakra strength? Should I just keep practicing ninjutsu?"

[Great Sage※: The host can directly assign 'Boil Release' and 'Fire Release' to the skill slot for passive enhancement.]

Boil Release?

Fire Release?

Shigure blinked in surprise. Then, without hesitation, he opened his skill bar.

Faced with a long list of potential options, he quickly searched for Boil Release and Fire Release.

"This is…"

Oh! That's right!

Both Boil Release and Fire Release are nature transformations—and apparently, they count as skills too. Which means… almost any chakra-based ability could be added as a skill.

And then, a bigger idea struck him.

"If Boil Release and Fire Release are considered skills… then what happens if I equip them as passive skills?"

"Would using jutsu under those elements consume no chakra?"

He didn't wait for confirmation.

[Passive Skill: Boil Release]

"Boil Style: Scalding Torrent!"

Boom!

A jet of searing steam and water exploded outward, ripping through the surrounding forest. The trees along the attack path splintered and cracked. A huge swath of trunks were snapped or flattened outright.

The roaring stream rushed past Shigure, whipping his clothes around.

He stood still, watching the aftermath, hands trembling slightly.

"…No chakra consumption at all."

He could feel it clearly. Nothing had been drained from him.

By equipping both Boil Release and Fire Release as passive skills, the system seemed to be bypassing the normal rules. He was changing chakra nature—and releasing powerful jutsu—without expending any of his own energy.

In theory, nature transformation consumes chakra because you're reshaping raw chakra into elemental form. But if this step becomes automated or passive?

Then it's like... manifesting elemental attacks out of thin air.

There was no cost.

"I didn't manage to develop a Kekkei Genkai like I wanted..."

"But I just stumbled across something even better."
