Konoha: Unable to learn ninjutsu, they had to develop their own.

and so……

Ban's conjecture is actually quite reasonable.

Tsunade was deep in thought.

"If it really is Madara, the Akatsuki organization must have had external help to persist until now, or it must have been dormant and in hiding for a period of time."

"By the way, I have another thought. If it really is Madara, back when Kushina-senpai gave birth and the tailed beast went berserk, was there possibly external intervention?"

Chiba said solemnly.

Tsunade opened her mouth, but couldn't find a reason to refute it.

No one understands Kurama better than Madara.

If such an organization truly exists, then the Nine-Tails' rampage within Kushina back then is indeed something to ponder—

While Jinchuriki are indeed weakened during childbirth, the Uzumaki clan possesses extremely strong physiques, and generally speaking, there is no possibility of a Tailed Beast going berserk.

at this point……

Mito Uzumaki back then was proven.

and so.

Someone intervened at that time, broke the seal on the Nine-Tails, and even controlled the Nine-Tails.

Tsunade narrowed her eyes: "If that's the case, this person is definitely not Madara Uchiha. He did indeed die at the Valley of the End, so he must be some Uchiha clansman?"

"I think so too."

Chiba lowered his head. "During wartime, it's too easy to escape under the guise of death, so it's probably difficult to verify their identity."

"Ah."

Tsunade narrowed her eyes, her mind racing. After a few seconds, she suddenly said, "You said the Uchiha clan massacre, is it possible that this guy was behind it all?"

"It's hard to say."

"Looking at it this way, the old man really is..."

Tsunade rubbed her head.

The Third Hokage and Danzo left behind a real mess. They didn't bother to investigate the underlying reasons for many things, and instead chose the simplest and most brutal methods.

bother!

She slammed her hand on the table and then slowly exhaled.

"This is a very plausible guess. Although we have no evidence, if we prepare a contingency plan based on this, we absolutely cannot let the other side obtain the Tailed Beast!"

Tsunade slammed her fist on the table. "First, we need to conduct reconnaissance. They'll definitely be coming to investigate again soon. I'll have the Hyuga clan on high alert, and you need to be extra careful too."

"The detection ninjutsu needs further development. Sound wave detection alone is not enough. Today I will modify the barrier technique and set the underground part to detect all chakra."

Chiba felt that Black Zetsu would definitely come.

Currently.

He was unable to detect the Black Zetsu intrusion through normal means.

but!

A firewall can be erected directly, and any data passing through it can be immediately targeted and attacked.

Chiba is currently using this approach.

"Great idea! Get it done quickly, the sooner the better, but your parasites..."

“The chakra of the parasitic insects is quite special and can be specially filtered. Unless it knows in advance that I set up a backdoor for the parasitic insects, it is absolutely impossible for it to detect it.”

"Okay, thank you for your hard work. Get things set up quickly, and it would be best to get it done today!"

This method is really good.

Tsunade's eyes lit up.

Aside from those sneaky spies, the other people in Konoha didn't need to crawl underground at all; he would be detected as soon as he came over using Earth Release.

Unless the opponent's abilities don't rely on chakra at all.

If that's the case, all their precautions will be in vain. And if the other party has that level of ability, they could just come in and assassinate them.

I don't believe the enemy has that capability.

Chiba went to the Anbu headquarters for a while, then pulled Inoichi and his men together to start modifying the barrier.

The main purpose is to add a sensing barrier to the underground.

Although there were some before, it seems that the enemy has infiltrated it to the point of being like a sieve. They know exactly where the loopholes are, and the entire underground of Konoha is like a backyard.

Instead of doing that, there's no need to disable it directly.

That very night, they completed the installation of the barrier, allowing them to monitor everything below the surface of Konoha, including the underground settlements of those clans.

They conducted several tests.

feasible!

As long as chakra is used, it will be detected and sensed immediately. Although it is impossible to pinpoint the exact location, it can define a basic area.

If the White Zetsu were to return, there would be no need for the troublesome sound wave detection.

of course.

Acoustic exploration and detection must continue.

A single defense will definitely have vulnerabilities, and Chiba is considering adding some more changes.

such as--

By studying the structure and abilities of White Zetsu and using the Iron Wall of Sealing in reverse, a barrier ninjutsu specifically designed to identify chakra was developed for this type of physique and ability.

Firewall, virus scanning, and targeted patches.

Only when all three are combined can it be considered a relatively safe protection.

Chapter 273 Fighting Hei Jue: Endless Joy

"We'll be at Konoha soon, right?"

"Ah."

Jue quietly emerged from the trees, cautiously observing the surroundings.

Konoha's patrols and vigilance are dozens of times stronger than before.

Putting everything else aside, there were several squads patrolling within his perception range, and each squad was equipped with members of the Hyuga and Aburame clans, as well as some ninja dogs.

They look like they're not to be messed with.

"The security measures are very tight!"

Bai Jue chuckled, "Should we go in and take a look? It would be troublesome if we got caught."

"try it."

This kind of ninjutsu-style reconnaissance can be dealt with and countered with ease as long as you understand the opponent's principles.

"That together?"

It can only be a detection method similar to a chakra wave. As long as it blocks a part of it, it can be used as bait and cover to avoid some of the enemies.

Black Zetsu said to him, "The chances of being discovered will only increase if we infiltrate again."

If it's some kind of bloodline limit ability, then he can only consider giving up or having Obito come and forcibly kill the opponent.

"You create a clone and let it attract their attention in your place, then we hide under it and sneak past."

"Hmm, let's try it without going around them first."

The three teams were lured by the clones and didn't discover the deeper areas of the Jue, but Jue soon discovered that there was another patrol area ahead.

That's not a problem.

As for ninjutsu...

There seemed to be a chakra fluctuation just now!

Bai Jue was somewhat incredulous.

Black Zetsu remained calm.

With such tight security, it would be strange if anyone could sneak in!

Black Zetsu said coldly, "We must know what methods Konoha is using, otherwise it will become very difficult for us to gather intelligence in Konoha in the future."

He quickly came up with a solution.

"No, the old methods won't work anymore. We're still on the outskirts of Konoha, and they'll definitely raise the alarm once they realize it's a decoy."

In fact, he did successfully evade Chiba's first blockade.

"Can it be done?"

In the past, it would have been virtually impossible for Konoha ninjas to detect them, but this time was different; Black Zetsu sensed something was wrong the instant he passed by.

"It's a ninjutsu technique. I don't know what kind of ninjutsu it is, but we've definitely been discovered, and they're looking for us now."

Bai Jue couldn't help but want to curse from underground.

Thankfully, I'm not alone today.

Just a moment.

"Withdraw!"

Did they use some kind of ninjutsu?

What he fears is that kind of unreasonable bloodline limit.

Black Zetsu didn't know what kind of ninjutsu Konoha used, but he didn't think it was some kind of sensory ability, because that kind of ability was useless to him.

Black Zetsu immediately sensed something was wrong.
