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

The ninjutsu is the Rasengan.

Chiba walked out of the research lab.

After some analysis, Chiba realized that his strength was already quite formidable.

"Even so, Sage Mode is only at the level of Hashirama Senju... I still need to become stronger!"

As for swordsmanship...

And now.

The next step is to study the seven-day breathing method.

Although we don't know what the effects will be, it's still a direction for research.

It's actually quite simple; for a short period of time, you can just try replacing the chakra with sage chakra.

Chiba pondered this in his heart.

Chiba held the scroll and pondered for a moment. After a few seconds of thought, he sighed softly.

It seems...

The research can't proceed for now.

"I'm going to the Anbu. I won't be back today."

"Yes, I will protect the research institute."

"You should practice your ninjutsu more. Although the Aburame clan needs parasitic insects more, you yourselves can't be too weak."

"Yes!"

Aburame Muta felt ashamed.

She knew that Chiba was not satisfied with the previous results.

Chiba captured Jirobo single-handedly, while his guards and the Anbu failed to capture any of the three.

Although we weren't completely wiped out, it's nothing to be proud of.

"I'll give you a copy of the ninjutsu later."

"Yes!"

……

Konoha's intelligence department.

"Lord Hai, would you like to try again?"

"Wait a minute, his mental energy is already very chaotic, let him rest a bit more."

Yamanaka Inoichi shook his head.

and.

He knew very well that although he had used mental energy synchronization and borrowed the mental energy of other ninjas to strengthen and enhance his memory exploration, what he could obtain now was already the limit.

He sought Chiba's help hoping Chiba might have another solution; otherwise, exploring again would be pointless.

Ibiki frowned and said, "Chiba also studies mental power? Otherwise, let's wake him up and let me interrogate him."

"It's no use. He's a madman. I don't know how Orochimaru trained him to be so loyal."

Hai sighed softly.

Although not many memories were obtained, based on the remaining memories, Jirobo reactivated the "cursed seal" at the cost of sacrificing his life force before being captured.

This guy had no intention of living.

Ibiki's interrogation skills were indeed very strong, but what good was his interrogation skills against a ninja who was seeking death?

It makes no sense.

Ibiki was not convinced and wanted to say more, but at that moment, an ANBU ninja arrived.

"Lord Inoichi, Lord Ibiki, Lord Chiba has arrived."

"I'll go greet them."

Hai Yi showed a hint of excitement.

He rushed out the door, and at the corner of the base, he saw Chiba slowly walking towards him.

"Chiba-kun".

"Senior Haiyi, what kind of trouble is this that even you can't handle?"

Chiba seemed a little confused.

He had already taught Inoichi to synchronize his mental strength. With Inoichi's mastery of secret techniques, he shouldn't have been unable to uncover any information, much less be reduced to seeking help from him.

"Jirobo is dead?"

"No, but it's close. Before you defeated him, he activated the cursed seal with his life force, and then it seems his chakra was continuously drained by the parasitic insects. Basically..."

The meaning was clear even though the first part of the poem was not finished.

He's not dead, but he's almost dead.

Chiba Ryoun.

The parasitic insects absorbed too much energy, and Jirobo was constantly consuming his life force to create chakra. His spiritual energy was probably severely depleted, and his mental state was likely in a state of chaos.

He didn't have a good solution to this situation.

"I can't say there's absolutely a solution."

"Give it a try, it's better than having no way at all."

Hai Yi handed over a scroll as he spoke.

Chiba opened it and took a look.

These are memories unearthed from Jirobo's head.

The content is fragmented, but it mentions that there is a base in the Land of Grass.

This should be the base where Naruto and the others met at the Tenchi Bridge. Later, Naruto activated the Four-Tails there and fought Orochimaru.

He pondered for a moment and said, "You want to dig out information about this stronghold now?"

"Correct."

Hai nodded.

Communicating with intelligent people is indeed effortless; Chiba understood completely without me even having to say anything.

Chiba walked toward the intelligence department.

On the way, he pondered how to further gather intelligence.

After much deliberation, the only solution seems to be mental synchronization, but I don't know if I can be the final piece of the puzzle.

"Senior Haiyi, have you tried using mental synchronization?"

"I've used it. This intelligence was discovered by using mental energy synchronization and borrowing the mental energy of others."

Haiyi explained.

Chiba nodded: "Then let's try mental synchronization first, and see if there's a way to improve it."

"it is good."

Hai's goal was precisely to get Chiba's help from the perspective of "technique".

It would be great if we could improve the mental synchronization technique!

They arrived at the intelligence department.

Chiba had them use mental synchronization once, then he spread his senses to observe their state, and finally adjusted his mental energy...

It instantly merged into their mental energy frequency.

A hint of surprise flashed in Hai's eyes.

Is Chiba really only thirteen years old, possessing such a level of mental strength?

How outrageous!

No wonder Ino's techniques had no effect on Chiba.

It's not that Ino is too weak, but that Chiba's mental strength has completely overwhelmed Ino.

Even though he was under the spell, Chiba was still able to regain control of his body with his strong mental strength and willpower. Even if the spell was cast by an ordinary mountain tribesman, it probably wouldn't have worked.

Perhaps only I can succeed.

Hai was astonished.

I'm thinking about it...

The other party withdrew from mental synchronization.

Hai opened his eyes and looked at Chiba.

"How about it?"

"Yes, there is some wear and tear."

"Is there a way to solve?"

Hai Yi hurriedly pressed for more information.

"Everyone's mental strength is different. Even if we try our best to simulate it and make each other's mental strength state closer to the same level, it is still impossible for them to be exactly the same. Losses are inevitable."

"It still doesn't work. It seems we'll have to try together, albeit reluctantly."

Hai sighed regretfully.

With Chiba's talent, he could certainly come up with a solution given more time, but asking him to come up with a solution before Jirobo's situation worsens is really asking too much of him.

Ibihi frowned.

Placing all his hopes on his child put too much pressure on Chiba.

but.
