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

Shizune blushed instantly and bowed in apology: "I'm sorry, I was too excited just now, so for a moment... let me think about it carefully!"

She thought for several minutes, summarizing almost everything she had learned in her life, and then nodded emphatically.

"If your observation is correct, it is possible in a sense, that is, the life force needs to be extracted from the cells of the first generation of adults... Further research may be needed."

"Right, hehe, so..."

"understand!"

Silent nodded emphatically.

I'm just a mouthpiece.

What Chiba really wanted to ask was Tsunade's opinion.

Chapter 249 Chiba, You Are the Reincarnated Sage of Six Paths

"Bone regeneration technology?"

After Tsunade finished her bath, she vaguely heard Shizune outside mentioning a technique used by Chiba.

She dried her hair, then picked up the notes that Jingyin had handed her, looked at them for a while, and finally pondered, "It can indeed achieve bone regeneration to a certain extent."

The bone structure was achieved using ninjutsu.

Viability culture of intercolumnar cells extracted from bone marrow to produce hematopoietic stem cells.

Tsunade looked out the window.

"Lady Tsunade, what's wrong?"

"It's nothing. I'll talk to Chiba about this technique later. You can be in charge of researching the direction of creating bones with chakra. If we can create it, it will be very useful as a supplement to bone repair surgery."

Tsunade just couldn't understand...

"I'm trying to make it even stronger."

Now is the time to verify its feasibility.

A voice rang out that surprised him.

We can't put all our hopes on that kind of thing.

Tsunade left a note beforehand, made an excuse to run away, and asked Shizune to temporarily take her place at the Hokage Building to handle the documents.

"Ah this."

She didn't quite understand.

……

Tenten turned around in surprise: "Lady Tsunade?"

Mainly on the legs and hands.

Barrier reinforcement can be performed surgically.

He was attempting to use a barrier to modify and enhance the overall defensive capabilities of his skeleton.

If Might Guy's skeletal defenses can be strengthened, his combat abilities at the seventh level and above will also be greatly enhanced.

Why did Chiba suddenly come up with this ninjutsu? Could it be that he suddenly had an inspiration while researching Kimimaro and wrote down a new ninjutsu concept?

This seems to be Chiba's style as well.

and.

As a medical ninja, Tsunade knew better than anyone the dangers of that thing.

Chiba wanted to strengthen himself for a very simple reason.

She could vaguely tell that the barrier and sealing technique set up by Chiba were intended to bind chakra and concentrate the injected chakra around the bones.

Watching from the sidelines every day, his expression was indescribable.

The other thing is.

In terms of medical ninjutsu, the current skeletal system is indeed not very advanced, and older medical techniques relied more on general-purpose medical ninjutsu to achieve recovery.

They said they'd be back at noon, but Jingyin felt it was highly unlikely.

We must find another way.

the next day.

Shizune felt a chill run down her spine when she thought of Raikage's volatile temper.

But it's actually quite useful.

He originally planned to wait for Bodhi Seed's feedback, but firstly, this kind of thing is a bit of a gamble, and secondly, it's still uncertain whether bone regeneration technology will actually work.

Chiba tried several times, but all attempts ended in failure. He sighed with regret.

What are you researching?

"Chiba-kun, what's wrong with you?"

Many techniques were like this before.

The human skeleton doesn't actually need much reinforcement.

It provides a detailed analysis of bone structure, regeneration principles, and even resolves the bone marrow culture protocol. The only problem is—

but.

Chiba's notebook is different.

"I hope Lady Tsunade can return to her office before Lord Raikage comes looking for her, otherwise, given the Raikage's temper, I really won't be able to handle him."

Is it really possible to artificially strengthen bones?

therefore……

I can strengthen myself with Bodhi seeds, but Teacher Kai and the others can't.

Why reinforce this kind of thing?

Bone marrow production involves intercolumnar cells.

"Ah."

Tsunade nodded slightly, then looked at Chiba.

She watched for a while, but really couldn't figure out what Chiba was trying to do.

Aren't we researching the Kimimaro treatment plan?

What's with all this bone research?!

Is it possible...

"You want to break the Corpse Bone Pulse?"

"No, it's mainly about coordinating Breathing Activation Technique and Eight Gates Formation. At the fourth or seventh gate and above, these two techniques could potentially injure oneself in combat..."

Chiba then elaborated on his "thoughts".

Tsunade squatted down.

After glancing at it for a few moments, she said, "Your idea is to use surgery combined with a solidification barrier technique to strengthen it?"

"Correct."

Chiba nodded. "As for Kimimaro, I also have some thoughts on that, which I'd like to discuss with you."

"You said."

"Could we use a method similar to Hidan's to combine his body with the cells of the First Generation? Who knows, it might even allow the Corpse Bone Pulse to advance."

Chiba shared his thoughts, "At worst, we can use a cursed seal to prolong his life."

Tsunade was stunned for a few seconds, and couldn't help but admire this guy's ingenious idea.

This line of thinking...

No normal person could ever come up with that!

Orochimaru will definitely resonate with Chiba.

but.

Compared to Orochimaru, Chiba's methods were much gentler.

If it were Orochimaru, he might have already started human experiments.

She thought about it.

Hidan's body has achieved a certain degree of immortality.

If one could achieve immortality or a Sage Mode state by using Hashirama's cells and the cursed seal...

It can indeed solve Kimimaro's problem.

even.

Kimimaro might become stronger as a result.

Tsunade couldn't help but have other concerns.

After spending some time together, Tsunade felt that Kimimaro's personality and character were quite good, and in a sense, he was trustworthy, but this was on the premise that Orochimaru had not been resurrected.

If Orochimaru were to be resurrected by someone, Kimimaro's loyalty would be questionable.

Konoha, Orochimaru.

Who will he choose?

Tsunade looked at Chiba, hesitated for a moment, and then voiced her concern: "What if Orochimaru is resurrected?"

“I trust him, and I will explain it to him clearly. I will make some preparations within the cursed seal.”

Chiba replied.

"Will he agree?"
