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

"It seems they were quite efficient. Sora was basically unharmed. He must have been taken into custody as soon as he arrived in Konoha, without giving him any chance."

He didn't conceal his presence, so...

The Death Forest is now the perfect prison. All dangerous individuals can be imprisoned here. With methods like parasitic insects and Thousand Leaf clones, they can be kept under close surveillance.

They emerged from the forest, and soon two ANBU ninjas appeared before them. Upon seeing that it was Chiba and his group, they bowed and then disappeared again.

Chiba nodded, then led Yamato, Tenten, and the others away from the forest.

That's it.

First, it was infested with bad insects.

Chiba turned around and smiled, "Let the Hokage have his fun first. How was yesterday's battle?"

"Uh."

Kakashi pondered for a long time, and finally said with a strange expression, "I want to know exactly what extent you improved the Breathing Activation Technique. Choza's technique was too exaggerated!"

"Oh? Did you go with Ding and the others yesterday? Well, it seems that Teacher Kai's third class went on a mission."

Chiba Ryoun.

Konoha had been attacked by Orochimaru and Sunagakure. In the meantime, many missions were put on hold in order to rebuild Konoha. After this period of restart, most of the more capable teams went on missions.

If even Kurenai's Class 8 has started taking on C-rank missions, then Kai's class could probably try out B-rank missions.

They simply don't have time right now.

but.

With clan leaders like Kakashi, Ino-Shika-Cho, and Shizuka Aburame in Konoha, the village currently has very few enemies that can truly be considered a threat.

Except for a few film-level works.

He sat by the fence, smiled, and said, "It's just the fourth change that uses breathing to enhance the body's activity. I call it the fourth activity."

"A fourth activity?"

Kakashi was puzzled when he saw Chiba hand him a notebook, which had been turned precisely to the page about the fourth activity.

Then he saw the description of the fourth activity—

By using the Expansion Technique or compressed air tools to inhale a large amount of air in a short period of time, the body is put into a state of extreme activity, and the body's strength and speed are greatly enhanced.

If combined with the Multiply Technique...

No wonder!

A knowing glint flashed in Kakashi's eyes.

"If this technique is further developed, it will almost be equivalent to another form of the Eight Gates Formation."

"Incredible!"

He couldn't help but exclaim in amazement.

Ideas like Chiba's are not uncommon, but the ability to extrapolate to the fourth activity level in such a short time...

I have to say, Chiba's brain is really sharp!

Kakashi then thought about Chiba's subsequent research.

The second activity incorporates physical techniques such as exceeding limits.

Then.

Further enhancements to Breathing Activation Technique will inevitably require the integration of Chakra Armor techniques.

"The difference between the Eight Gates Formation and the Breathing Revitalization Technique is that the chakra of the Eight Gates Formation is too powerful and violent to be used by oneself."

Chiba seemed to see through Kakashi's thoughts, "But the Breathing Activation Technique doesn't. It only enhances bodily functions; the chakra can still be controlled."

"Yes, but correspondingly, respiratory activity... it increases cell division, which in a sense is a ninjutsu that reduces lifespan."

Kakashi's tone was serious.

This is not a regular ninjutsu, but a forbidden technique!

"However, in battle, sometimes using these kinds of explosive ninjutsu might save a ninja's life, so it's really hard to say which is better or worse..."

Kakashi added the details himself.

As ninjas, we live a life of constant danger and cannot give up because of a minor setback.

He pondered for a moment, looked at Chiba, and frowned, saying, "You've told me all this, so you don't plan to study it for a while?"

"Yes, this technique is very valuable, but I don't have time to study it, and I can't study it either. In the future, it will definitely require the cooperation of ninja tools, ninjutsu and other aspects, which I am not ready for now."

Chiba then gave a general explanation of the Akimichi family's current predicament—

Air!

After the Akimichi clan multiplies, their bodies become larger and stronger, thus increasing their need for air. If they can absorb enough air, their destructive power will be incredibly astonishing.

But here is the problem.

Where does all that air come from?

There's only so much air in a space; once it's sucked dry, replenishing it requires unconventional methods.

This requires the use of other techniques in conjunction.

such as……

Ninja tools, space-time ninjutsu.

This is where Chiba needs Kakashi's help.

"If there is enough air, it may be possible to enter the fifth level of activity. According to your description, yesterday Lord Ding's breathing was accompanied by some red aura, which may be the blood aura accompanying his breathing."

After careful consideration, Chiba said, "After the fifth activation, these blood mists may also be used in combat, or we can try to develop and utilize the blood energy in the fourth activation state."

"I see."

Kakashi nodded solemnly.

He had heard Kai talk about some techniques of the Eight Gates Formation, and in a sense, the Breathing Activation Technique and the Eight Gates Formation could learn from each other.

"Chiba, you?"

"Yes, Kakashi-sensei, I plan to leave Konoha for a while to travel around and see other parts of the ninja world. I'll also help the Daimyo train some ninjas, and..."

Chiba shared his thoughts.

I've said it for the third time; there's no need to think twice. I'll just explain the whole process directly.

After listening, Kakashi pondered for a moment and said, "Your idea makes some sense. The research department is indeed too reliant on your brilliant ideas, which is not a healthy development."

"When the First Hokage was alive, Konoha was invincible in the ninja world. But what happened after that? After the First Hokage died, Konoha began to decline."

Chiba looked into the distance and said, "Our generation cannot afford to see this happen again."

"Ah."

Kakashi nodded.

Yesterday's battle showed him Konoha's current fighting strength.

The Akimichi clan has learned Chiba's secret technique, allowing them to unleash such terrifying power in an instant, so...

What about the Aburame clan, the Yamanaka clan, and the Inuzuka family?

Obviously.

While Konoha may not have the same population or number of ninja as other villages, its overall strength is now incomparable.

just.

Everyone's awareness and combat experience are still stuck in the past.

This will not work.

Even after mastering the skills, one still needs to hone them.

"I'll teach Sasuke myself, since you can't always take him with you."

Kakashi said.

Chiba considered for a moment and said, "Let him train in the Anbu for a while, and I will come and take him away when the time is right."

"Alright."

Kakashi nodded.

If Chiba is willing to take him along, then naturally Chiba's teaching ability is stronger.

Although it's a little embarrassing, it's an undeniable fact.

Kakashi opened his mouth, but for a moment he didn't know what to say.

In less than two years.

Chiba transformed from a genius into a pillar of Konoha, someone even he himself could only look up to—such ability…

There doesn't seem to be anything worth entrusting them with.

On the contrary, if Chiba went on a trip outside and returned to Konoha only to find that he still hadn't mastered Sage Mode, the teacher would lose face.

Kakashi couldn't help but smile, and pulled out his "Adorable Violence" card, saying, "I won't say much more. Take care. I'll give Tenten and the others lots of guidance, so you can rest assured."

"Hmm, this is a good opportunity to form a new class."

"Sakura?"

Kakashi paused for a moment, then nodded in agreement.

Chiba left, Sasuke joined the Anbu, and Naruto left the village with Jiraiya.

For the next period of time, Sakura was all alone.

Forming a new class with her and Tiantian and the others is a viable option, but...

"This must be the first all-female ninja class, right?"

Kakashi had a bit of a headache.

The saying "three women make a drama" is no joke; he had already foreseen his troublesome future.
