It means the Seal in the Main Family's hands is a "transmitter."
And the Caged Bird Seal on the branch family member's forehead is a "receiver" implanted in the body.
Between the two, there exists an invisible Chakra signal connection.
Just like when a Genjutsu Ninja performs an illusion, although there is no contact.
They can link to the opponent's brain through Yin Release Chakra to produce illusions.
Since the "receiver" bomb growing in the brain cannot be removed.
Then why be obsessed with defusing it?
Wouldn't it be enough to just make it so the bomb can't receive the detonation signal?
Aokawa's pupils contracted slightly.
This was just like radio interference from his previous world.
Even if the transmitter turns the signal power to the maximum, as long as the receiving end is wrapped in a shielding cover, the signal cannot enter.
The bomb won't go off!
No complex unsealing is needed, nor is risky nerve excision.
He only needed to add a "shell" to the exterior of the Bird in a Cage Curse Seal.
A miniature barrier capable of completely isolating Yin Release Chakra signals.
To lock this "bird" in an absolute quiet room where not even sound can penetrate.
This is—a "Signal Jammer" on a physical level.
Aokawa's fingers tapped unconsciously on the wooden post, the rhythm getting faster and faster.
The train of thought was clear.
But new difficulties followed.
To carve another layer of isolation Seal inside his own brain, on the outer layer of this already crowded curse Seal.
This was no different from carving "Along the River During the Qingming Festival" on a grain of rice.
Moreover, this Seal must not interfere with the normal operation of the brain; it must only target specific Chakra frequencies.
While the Yin-Yang Seal and Four Symbols Seal were exquisite, they leaned more toward "suppression" and "storage."
They weren't delicate enough, nor did they possess precise filtering functions.
To complete this idea, he needed higher-precision "Barrier Ninjutsu" and top-tier theories regarding "Chakra isolation."
Looking at the entire Ninja World, there was only one person who could play with Sealing Techniques to such an extent, even reaching the spatial level.
The heir to the Sealing Techniques legacy of the Uzumaki Clan.
The current Battlefield commander-in-chief.
Minato Namikaze.
Aokawa turned and ducked back into the tent.
He quickly destroyed all the draft papers on the ground, leaving only a blank scroll.
Since even Tailed Beast Chakra could be isolated, and the Chakra of a husband and wife could be sealed within Naruto for over a decade.
Isolating a signal shouldn't be a problem, right?
...The next morning.
Outside Minato Namikaze's tent, Aokawa stood quietly.
Before long, the flap was lifted.
Minato Namikaze, wearing his Ninja flak jacket, looked slightly tired, clearly having spent another sleepless night.
Seeing Aokawa, he smiled gently.
"What is it, Aokawa? So early."
"Regarding that Sealing Technique..."
Aokawa took a step forward and handed over the scroll in his hand, his tone sincere and urgent.
"While I was deducing it, I found a very interesting problem. If I don't solve it, I really won't be able to sleep."
Minato Namikaze took the scroll and scanned it casually.
His originally gentle gaze froze instantly.
He snapped his head up, his azure eyes bursting with an astonishing light.
"This is... you want to block a specific frequency of Chakra?"
"Yes."
Aokawa nodded, pointing to the unfinished ring on the scroll.
"I was thinking, if a certain kind of Chakra could be isolated like sound, would it be possible to..."
He paused, not finishing the thought.
Minato Namikaze was also a smart man; there was no need to spell it out.
This was hardly just wanting to learn Sealing Techniques.
This was clearly... "Come in."
Minato Namikaze stepped aside, his tone becoming serious and earnest.
"Tell me your thoughts just now in detail."
