Chapter 25 - [Spiritual Sealing Technique – Slave Mark], Planting a Spy Back into Danzo’s Ranks

"You don't believe me? You actually don't believe me?!"

After hearing this, Danzo Shimura's eyes turned bloodshot as he snapped:

"I told you—I didn't do it! I didn't—means I didn't!"

With that, he stormed off in a rage.

Whether he was truly angry—or simply using it as an excuse to escape the topic and bury the matter—no one could say.

Meanwhile, Hiruzen Sarutobi sighed inwardly:

Danzo… I hope you can turn back before it's too late.

Recently, he noticed—

The number of arguments between him and Danzo had been increasing.

And he didn't know why.

On the way back—

Danzo's face remained dark and twisted as he thought:

Who's plotting against me?

Suddenly, he thought of the four Root elite jonin he had sent to capture Uchiha Sora—

They still hadn't returned.

Could it be… Uchiha Sora?

But then he shook his head.

Impossible. No matter how talented, he's just a three-year-old child.

Then it must be Uchiha Masayuki!

His eyes narrowed coldly.

That bastard may look rough, but he's hiding deep cunning… Typical Uchiha.

That clan should never have existed.

Just wait… I'll destroy all of you. I swear it.

Whether his deduction was correct—

Didn't matter.

He had already decided:

It was the Uchiha.

One week later—

[You have fully analyzed the structure of the Tongue-Sealing Curse Mark. Major insight achieved. You have mastered both its application and removal methods.]

[Through deeper study and integration with your knowledge of sealing techniques, you achieve enlightenment. You create: Spiritual Sealing Technique – Slave Mark.]

[Slave Mark]:

A spiritual imprint constructed using mental energy and implanted into the target's consciousness.

Targets with weaker mental strength have a high probability of being enslaved. Over time, they will be subtly brainwashed into absolute loyalty.

"...Tsk. This technique is really sinister."

Sora smacked his lips as he processed the newly created technique.

"But… it's perfect for dealing with enemies and evildoers."

"Combined with my spirit cultivation… it's practically a divine skill."

At this point, his mental strength had already surpassed most Kage-level experts.

In a few years—

There would be almost no one in the shinobi world who could rival him mentally.

"Since this was created thanks to you…"

"Let's test it on you first."

Looking at the four Root ninja before him, Sora formed a Slave Mark using pure spiritual power—

And directly implanted it into one of their minds.

"AAAAHHH!!"

The ninja immediately began convulsing violently.

After a long struggle—

He finally calmed down.

With visible resistance still lingering in his eyes, he bowed:

"…Jiu… greets Master."

"Good."

Sora nodded in satisfaction.

He could clearly see the resistance—

But it didn't matter.

Sooner or later, the mark would completely overwrite his will.

With the vast difference in mental strength—

Escape was impossible.

The remaining three Root ninja watched everything unfold—

And felt a deep chill in their hearts.

This technique…

Was even more terrifying than Danzo's curse mark.

"AAAAHHH!!"

Soon, all three were implanted as well.

Next—

Sora modified the curse marks on their tongues.

He removed Danzo's control—

Yet kept the structure intact to avoid detection.

Then—

He unsealed their chakra.

Finally, he gave his orders:

"Return to Danzo."

"Monitor everything he does."

"Gather evidence of all his crimes."

"Report back when the time is right."

"And most importantly—"

"You will never expose me or my family."

"You're professionals. I trust you know how to fabricate a convincing story."

"I don't need to teach you that."

He wasn't entirely sure—

Whether Danzo would suspect anything.

This was a test.

"Understood."

The four obeyed immediately.

But then, Jiu spoke:

"Master… I suggest only two of us return."

"The other two should remain by your side under new identities."

"This will make the story more believable."

"If all four of us return unharmed after being missing for a week…"

"Danzo will definitely grow suspicious."

"Even with just two of us, we must appear injured."

Sora raised an eyebrow.

"Reasonable."

"Do it your way."

"Go."

"Understood."

Immediately—

Jiu and Ya departed under the guidance of a shadow clone—

Vanishing into the Uchiha district.

Sora then turned to the remaining two.

"Names. Specialties."

"Master, I am Bange. Skilled in Earth Release and swordsmanship."

"Master, I am Xie. Skilled in genjutsu and Wind Release."

"Good."

Sora nodded.

"You'll stay with me for now."

"New identities. Await further orders."

Then he paused.

"The problem is… your chakra signatures."

"Danzo likely has them memorized."

"They need to change."

He began rapid mental deduction.

Within minutes—

[You have derived a new technique through deep understanding of chakra.]

[Chakra Concealment Method]:

Allows suppression and alteration of one's chakra signature.

"Done."

Sora immediately taught the technique to both of them.

"Master…"

Their eyes filled with shock.

He created it… just like that?

What kind of monster was this?

At that moment—

Their fear deepened.

But strangely—

So did something else.

Respect.

Because compared to Danzo Shimura—

This new master…

Didn't treat them like disposable tools.

And for the first time—

They felt that becoming his subordinates…

Might not be the worst fate.
