This puppeteer is a bit... well...

Chapter 91 Trading

Konoha Hospital.

Looking at Kuro doing rehabilitation exercises in the backyard, Ryuji asked, "Is there anything wrong with this right arm? Has there been any delay in command?"

"No, the transplant was a success," Black replied, waving his right arm.

"That's good."

Ryuji nodded slightly. "This right arm is the same as Silver's. It has great strength and endurance, which can make you much stronger."

Black's ninjutsu is Lightning Release, and his strongest technique is Taijutsu—a Lightning Release chakra armor.

This means that the lightning covers the entire body, which at the same time protects the body and activates cells, thereby amplifying bodily functions and enhancing explosive speed.

but.

If one's own strength is insufficient, no matter how fast one is, one will not be able to harm certain individuals.

When a balloon and an iron ball collide with a wall at the same high speed, the balloon will either bounce off or burst due to the high-speed air pressure, while the iron ball will break through the wall.

With this arm, Black won't be kicked away by an enemy like Tsunade when using ninjutsu.

Their strength has made a leap forward.

"Thank you, Master."

Hei replied calmly, his voice remaining as steady as ever, even though his strength had greatly improved, showing no trace of joy or sorrow.

"Take good care of yourself. Once you're fully recovered, you can continue to study the application of ninjutsu."

"Yes."

……

After saying goodbye to Kuro, Ryuji prepared to go back.

For the past few days, he has been working on the arm for Black, and many of his studies have been suspended.

He now needs to go back to continue his other research.

Although the observation instrument and 3D printer are no longer available, there is still much to study.

After passing through the inpatient area, Ryuji was stopped by Tsunade in the outpatient area.

At this time, she had not yet put on the green trench coat with the word "gamble" printed on the back; she was only wearing a green vest like a Jonin, but her figure, appearance, and even temperament were almost identical to her future image.

He didn't stare at the other person, as that would be impolite; he simply glanced at them briefly before asking, "Is there something you need?"

Upon hearing this polite inquiry, Tsunade frowned, but quickly relaxed.

"I just came out of a dark hospital room," Tsunade said casually. "How did you get his prosthetic leg?"

After saying that, seemingly worried that Ryuji might have misunderstood, he immediately added, "I mean, how is it connected to the brain's nerves?"

It's not difficult to reattach a severed limb; the challenge lies in enabling the person to move normally as before the limb was severed. The human body operates by transmitting commands from the brain to the central nervous system, and every part of the body is directly connected to the central nervous system.

If a part of the body separates from the body, the connection between that part of the body and the central nervous system will also be severed.

Even if a prosthesis is installed or a severed limb is reattached, the connection with the central nervous system cannot be restored, and the limb cannot move like a normal limb; it is merely an unmovable ornament.

In this era, even with omnipotent chakra, this problem (referring to normal people) could not be solved.

"Are we that close?"

Ryuji almost laughed.

He understood better than anyone what neural link technology meant in this world of constant war, and therefore found Tsunade's behavior amusing.

They're not related to me, and they have no sincerity whatsoever, yet they come directly to ask about this cutting-edge technology.

Why do you think someone else will give it to you?

Hearing these blunt words, Tsunade raised an eyebrow, her temper about to flare up.

But considering the other person's identity and that he was the one asking for help, he suppressed his impulse.

She let out a deep breath and flashed a familiar smile. "Look at what you're saying, Sunagakure and Konoha are allies, right? Aren't the kids you sent here to study also learning advanced medical ninjutsu and systems from us?"

Ryuji didn't speak, he just watched quietly.

Tsunade continued to smile familiarly, then her face fell.

"Bang!"

Tsunade slammed her hand on the corridor wall, creating a deep crack, and glared at Ryuji through gritted teeth. "What do you want in return for telling me?"

"You want to make a deal with me?"

Long Er tilted his head and looked at her with amusement.

"That's right."

Tsunade took a deep breath, trying to calm her previously furious emotions.

After a moment, she calmed down and looked at Ryuji seriously. "Let's make this clear first, there are many things in Konoha that I can't make decisions about, so don't make any unreasonable requests."

"Then let those who can make the decisions do the talking!"

After saying that, he left without waiting for Tsunade's reaction.

Tsunade reached out and blocked their way.

She lowered her head, bit her lower lip tightly, her hands clenched so hard they cracked, and her eyes, hidden by her bangs, were full of hesitation.

Clearly, she was struggling with something inside.

"What do you mean?"

Upon hearing the question, Tsunade's expression of struggle intensified, but she immediately relaxed.

"I'll trade you this." Tsunade said, taking an emerald crystal necklace from her neck and handing it to Ryuji. "This is the necklace the First Hokage once wore, worth three mountains of gold. Is that enough to buy your technology?"

"not enough."

Long Er was slightly surprised, but after a moment's hesitation, he declined.

This necklace is made of chakra crystal and contains the chakra seal that was sealed by the First Hokage. It has a suppressive effect on the tailed beasts. Whether it is used to give to future Jinchuriki or for personal research to enhance the potential of Wood Release ninjas, it is comparable in value to neural connection technology.

Furthermore, as it is a necklace passed down from the First Hokage, its collectible value is unique, and it would be very worthwhile to sell it for money.

In particular, Sunagakure is currently facing a severe shortage of funds to build its mechanical castle.

With this necklace, the construction progress of the mechanical city can be accelerated by at least 20% to 30%.

but.

Asking for exorbitant prices, then haggling on the spot.

Tsunade was the one eager to make the deal; she didn't know that the necklace was so valuable to Ryuji.

Therefore, you can continue to bargain and ask for some benefits.

Finally, the two haggled over the price.

Tsunade used the First Hokage's necklace and all the data she had researched on the Yin Seal as bargaining chips to exchange for Ryuji's neural connection technology.

Tsunade reluctantly handed the necklace to Ryuji, saying, "Take this necklace for now. I'll organize the research data on the Yin Seal and give it to you later."

"You trust me that much?"

Ryuji took the necklace, checking its authenticity as he quipped, "I'm a Sunagakure ninja. After what happened a few days ago, you all probably wanted to kill me, right?"

"With so many of your Sunagakure people in Konoha, do you think I'm afraid you'll run away?"

Tsunade snorted, her face full of disdain.

At a time when most of our manpower is rushing to the front lines, Konoha may not be able to stop Ryuji from escaping, but the hundred or so members of the study abroad delegation... hmph.

Long Er was well aware of this, so naturally he would never consider running away with the goods.

"Alright, I'll go back and work out the neural connection technology, and I'll bring it to you tomorrow morning."

"That's settled then!"

I just got up and wrote one chapter. I'll go cook dinner first, and then I'll write the second chapter after I finish eating. I'll correct any typos after I finish writing the second chapter.
