The Heavens: From Naruto to sign in

A thin sheen of sweat covered Yoruha's forehead.

Though his face looked a bit pale from exhaustion, his eyes gleamed with excitement.

"Uncle Fuma, see? I wasn't lying. I really did it!"

Despite the sudden strain on his cells and mental energy, Yoruha had successfully done it.

Right now, a small stream of pure chakra was flowing smoothly through his meridians.

It wasn't much in quantity…

But the clarity, the stability of it—it made him feel incredible.

"Here—take this soldier's pill!"

Fuma instantly pulled a high-grade military ration pill from his pouch and handed it to Yoruha. His voice was serious, almost stern.

"You're absolutely reckless! You didn't even wait for me to teach you the basics, and you went ahead and tried chakra extraction on your own? What if you'd burned yourself out?!"

But deep down, he was rattled.

Shocked.

The chakra inside Yoruha wasn't just refined—it was exceptionally pure.

Even among most jōnin, chakra of this quality was rare.

Could it be… had his nephew actually awakened some kind of special bloodline trait?

"Haha, I couldn't help it. It just felt… right. Besides, I'm fine now—so you can start teaching me."

Yoruha popped the pill into his mouth. The strong medicinal bitterness gave way to a lingering warmth in his throat.Almost instantly, his energy began to return.

"Listen to me carefully." Fuma sighed, taking a seat across from him again.

"Refining chakra isn't something you can approach lightly.Each session requires proper preparation—mentally and physically.You extract energy from your cells and combine it with spiritual energy.If you mess up, it won't just be fatigue—you'll damage your foundation."

With that, Fuma began to break down the fundamental principles of chakra refinement.

He explained the circulation paths, the control techniques, the signs of overdraw…

And Yoruha listened with rapt attention.

But when the lesson ended, a question lingered in the boy's mind.

"Wait… if refining chakra is really that complex," Yoruha frowned, "then wouldn't ninjas constantly be in danger during battles, especially when they run out?"

Fuma's expression turned grave.

"Exactly. Chakra is the very foundation of a ninja's strength. Run out, and you're vulnerable."

"But," he added, "once you've mastered extraction, you can refine chakra even in combat.It's dangerous, though. Far more dangerous than doing it in a calm setting.You have to be sharp—completely focused. One slip, and you could damage your own body."

Yoruha nodded slowly.

He recalled how often Kakashi Hatake had to be hospitalized after missions.He wasn't exaggerating.

Overusing chakra really could wreck your body.

"Uncle Fuma, thank you for everything today. I wouldn't have made it this far without you."

Yoruha carefully memorized the entire scroll.Then, respectfully handed it back.

It was Fuma's private collection, after all.Keeping it would have felt wrong.

Fuma silently took it, then looked at the boy with a quiet, serious gaze.

"Don't let anyone know you've started training chakra. And don't let anyone see you practicing."

"Even if you're admitted into the ninja academy, keep your aptitude average. Barely pass if you have to."

"It'll be better for you. Don't ask me why."

As a veteran operative from the Root Division,Fuma knew what had happened in the forest earlier that day.

He knew Danzo had overlooked Yoruha not because of lack of information—but because of how weak the boy was supposed to be.

That weakness had shielded him.

But if Danzo caught wind that Yoruha was cultivating chakra now?

That protection would vanish.

And things would turn very ugly.

Yoruha gave a calm smile.

"All right, I won't ask if you don't tell. I'll just pretend to be dumber from now on."

You trust me…

So I'll trust you too.

Even though… I already know exactly who you really are.
