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

"There's still a lot of room for improvement."

Jiraiya frowned and pondered deeply.

Jiraiya nodded in agreement. "And we also have to consider the possibility of them changing shifts or being assassinated. Although their sensory abilities are very strong under this barrier, that guy can use space-time ninjutsu."

Jiraiya came over.

but.

Jiraiya was astonished.

But problems also arise.

The difficulty of completing such a barrier technique is no less than that of developing a new S-rank ninjutsu.

Jiraiya put his ideas into play and brainstormed with Chiba.

"Okay, so now you..."

The advantage is...

Think about it too.

"Jiraiya-senpai, if this thing is used for the base, how about I nest an energy-absorbing barrier within the perception barrier?"

There were indeed some people in the Dark Division who knew it, but their skills were so rudimentary that they couldn't be considered truly proficient. If Jiraiya hadn't tested it, he wouldn't have known that the Heavenly Canopy Formation had such high potential.

What about the other ninjas?

"We need to reduce the absorption efficiency of the energy-absorbing barrier to a level that is just enough to absorb chakra to supply the invincible magic array. It would also be best to add some improvements so that it can be adjusted at critical moments to absorb everyone's chakra and supply it to a few Jonin."

After opening the notebook, he quickly drew a rough sketch on it. Although it wasn't very pretty, you could basically understand what it meant.

Nesting such a barrier is tantamount to using weapons against one's own people.

He felt it was already perfect, but in other people's eyes it was just a preliminary version, and there was still a lot of room for improvement.

"That's one solution. By using an energy-absorbing barrier, we can directly absorb the chakra of the ninjas inside the base to maintain the barrier. In this way, the ninjas responsible for maintaining the barrier only need to provide a small amount of chakra."

Otherwise, how could they have discovered the situation of the Six Paths of Pain?

This?

Has the gap between people become this large?

Jiraiya pondered for a long time, unable to answer, before finally speaking, "Chiba, how can this be improved? I really can't think of anything."

"This version can only be learned by those who have mastered immortal arts, so it is destined that not many people can master it, and its control difficulty is also a little high."

Jiraiya was taken aback.

Chiba took out a pen and paper to write down, "It would be best to make some improvements."

"And another thing, what about chakra consumption?"

Chiba had a terrible headache.

Chiba explained.

He thought for a moment.

The controller does not need to consume too much chakra, and can even maintain sufficient energy with chakra feedback, so as not to quickly fall into exhaustion due to long-term attention to the surrounding movements.

"what?"

"Can it be improved further?"

"Yes, all of these issues need to be optimized."

Chiba counted on his fingers for him, "Normally, some sensory barriers don't require much chakra consumption, but barriers like this need to be maintained for a long time, and it's basically impossible to have several ninjas maintain them."

Above it was—

A heaven-defying magic array.

Energy-absorbing barrier.

At the center is a chakra battery, with the words "Tailed Beast Chakra, Cell Creation" written in parentheses next to it.

Jiraiya knew about the tailed beast chakra.

Chiba had been planning to plunder the tailed beasts for a while, and he even managed to catch half of Shukaku. In addition, he recently heard from Tsunade that he had also taken advantage of the Eight-Tails.

There may also be some transactions involving other tailed beasts.

and so.

Chiba has quite a lot of tailed beast chakra at his disposal.

but.

What are cellular creations?

Jiraiya pointed to the thing next to him.

The strange creature's name unconsciously reminded him of his former friend who was now half-dead.

Could it be Orochimaru's creation?

"It has nothing to do with Orochimaru."

Chiba saw through Jiraiya's thoughts and then explained, "The evolutionary ability of the insect race is terrifying, but at the same time, it also presents uncontrollable crises. Therefore, some insect races must be eliminated. My idea is to use them for Hashirama cell reproduction..."

He explained his thoughts in detail.

This is a concept for a "miniature" knock-off tree.

Hashirama cells and miniature replica trees, as the core of all barriers, also serve as chakra batteries.

Jiraiya pondered for a moment and understood how terrifying this thing was.

but.

He had to admit...

"If it can be realized, its effect will be terrifying, but if an accident occurs and it gets out of control, the entire Hidden Leaf Village may be destroyed."

Jiraiya said seriously, "This power should be restricted."

"So it's an alternative."

Chiba does not deny this.

Obito's strange abilities allowed him to ignore attacks from many people and force his way into these restricted areas.

That's how the Nine-Tailed Fox erupted that year.

The difference between Hashirama cells and Kurama cells is that Hashirama cells are easier to control in the early stages, but once they grow, they are probably more difficult to control than Kurama cells.

Obito's space is just enough to carry a bunch of living beings.

Chiba slowly wrote down some other plans on the paper, but he still didn't have any good ideas about the miniature replica of the Divine Tree, how to guard against Obito, and so on.

but.

He can try it himself first.

Others may fear Obito, but Chiba is not.

Obito's abilities are just unusual; his actual strength is currently inferior to mine, otherwise the Akatsuki would have attacked long ago.

"Well then, I know a bit about the Earth Prison Hall and the Energy Absorption Barrier, so I can help you with a little bit here, but I'm afraid I can't offer much help elsewhere."

Jiraiya said.

Chiba waved his hand.

"No rush. These projects can be broken down and distributed to everyone to brainstorm. Relying on ourselves will only lead to exhaustion. Let's talk about something else first."

"what?"

Jiraiya simply sat down on the ground, completely disregarding his decorum as he sat on the grass.

It seems.

Today is a protracted battle.

Jiraiya composed himself and prepared to endure Chiba's torment.

but.

Chiba simply asked, "How's the development of your Sage Mode coming along?"

"Well, it's much better than before. Now at least I can use it myself, it just takes a little longer. I need to prepare for a minute or two."

Jiraiya said.

Chiba smiled and said, "Sage Mode is not such an inconvenient thing. Now, not only me, but also Kakashi-sensei can activate Sage Mode by simply putting his hands together."

"..."

Jiraiya's lips twitched.

He had indeed heard some things about Kakashi, but he didn't know exactly how he did it.

According to Fukasaku, Kakashi should be the type of person who is not suited to training in Sage Mode, so how could he possibly have completed Sage Mode training?

This unscientific!

He just happened to find out.

After learning the whole story from Chiba, Jiraiya couldn't help but gasp, admiring and praising Chiba's amazing idea.

"You're a madman. You've transformed the chakra meridians into acupoints for the Yin Seal. Ordinary people simply can't do that. One wrong move and you could be seriously injured or even crippled."

"I have strong control over my chakra, so I won't get hurt even if something happens."

Chiba shook his head.

If he didn't have absolute control over his chakra, he wouldn't have dared to try so many ninjutsu, like dismantling hand seals and barrier techniques; a normal person would have been harmed by the backlash long ago.

Jiraiya pondered for a moment, then felt a headache coming on.

"To be honest, I have nothing to exchange."

He scratched his head, then his eyes suddenly lit up, and he slapped his thigh, saying, "I actually have a technique that I discovered by accident. I wonder if you'd be interested."

"What technique?"
