A Revolutionary Invention Capable of Turning the Tide of Battle!

Until the chakra in the scroll was exhausted, Shiraha unsealed it.

After wiping the blood from his palm, the wound had completely healed, leaving only a faint mark.

Tsunade hurried forward and excitedly grabbed Shiraha by the shoulders.

"Shiraha, how did you do this? Is this a Medical Scroll?!"

Tsunade and the Medical Corps had long tried many times to seal Medical Ninjutsu into scrolls.

When shinobi were injured while carrying out missions, ordinary medical supplies had limited effectiveness against serious external wounds if there was no Medical Ninja nearby.

But if they had portable Medical Ninjutsu scrolls like these for emergency treatment, it would be a completely different story.

Yet Tsunade and the Medical Corps had failed countless times and had long since given up.

Who would have thought Shiraha had actually succeeded!

If Konoha Ninja on the battlefield could be equipped with these Medical Ninjutsu scrolls, both their survival rate and mission success rate would rise dramatically.

If these Medical Scrolls could be mass-produced, they would be a revolutionary invention!

"Based on the Medical Corps' records, and with inspiration and help from Nonō-sensei, I successfully made this Medical Ninjutsu scroll. It contains the C-rank Medical Ninjutsu: Healing Jutsu, which can treat relatively minor external injuries."

Shiraha scratched his head, his shy smile carrying a hint of pride.

Upon hearing Shiraha's explanation, everyone turned in unison toward Yakushi Nonō behind them.

Nonō herself was somewhat bewildered. She tilted her head slightly as she looked at Shiraha, her thick Round Frame Glasses slipping down her delicate nose, her large eyes full of confusion.

Shiraha had asked her about making Medical Scrolls before, but she had only given him a few suggestions. How had she helped?

"Originally, I planned to give this scroll to Tsunade-sensei today and tell her the production process, so she could try sealing the Mystical Palm Technique into one. If it succeeds, then even without Medical Ninja on the battlefield, the injured will be able to administer emergency treatment themselves."

Shiraha continued.

"You're saying these Medical Ninjutsu scrolls can be mass-produced?!" The Third Hokage wore an incredulous expression.

Based on Shiraha's words, it was already obvious, but he still instinctively wanted to confirm it once more.

Tsunade had brought up Medical Scrolls long ago, and the Third Hokage had strongly supported the development of this new technology. Yet after expending enormous manpower and resources, they had ultimately gained nothing.

Although Tsunade had repeatedly emphasized Shiraha's talent for Medical Ninjutsu, the Third Hokage felt that he had still underestimated him.

A twelve-year-old Genin who had only recently graduated had actually overcome this hurdle.

A genius!

After all, the best Medical Ninja in the Shinobi World were in Konoha, and the Medical Ninja with the highest overall quality were also in Konoha.

Once these scrolls could be mass-produced, Konoha's overall combat power would be indirectly enhanced.

And it would be permanent!

Because of Konoha's total population limits, there were only so many new students with shinobi talent in each generation.

The more students who underwent Medical Ninja training, the fewer combat-oriented shinobi there would be, which would have an obvious impact on Konoha's future military strength.

Compared with spending five or ten years and massive manpower and resources to train Medical Ninja in large numbers, mass-producing scrolls would yield immediate results.

Medical Scrolls held immeasurable value for Konoha!

"Yes, I can demonstrate it on the spot right now." Shiraha nodded.

"Right now?!"

The Third Hokage subconsciously felt around his body, wanting to pull out his pipe and take a few puffs to calm himself down.

"Everyone except the Medical Ninja, leave and wait outside." Danzo gave the order with a grave expression. As his old partner, he understood without the Third Hokage needing to say anything.

"Yes!"

Though the Jōnin were all extremely curious, they obeyed the order and left the meeting room.

"Please make some room." Shiraha came to the table and took a Storage Scroll from his clothes. He then removed Blank Scrolls, as well as Special Brush and Ink.

Shiraha skillfully picked up the brush, used chakra to write special formulas onto a Blank Scroll, then rapidly formed hand seals and activated the Healing Jutsu.

Pale green chakra wrapped around Shiraha's palm. As he lightly touched the formula with his hand, the chakra on it was rapidly absorbed by the scroll.

The entire process took less than three minutes. A Medical Scroll containing the Healing Jutsu was complete.

"This..."

All the Medical Ninja stared wide-eyed. If not for the Third Hokage and the other higher-ups being present, they probably would have rushed forward to inspect it up close.

"It truly succeeded!" Though the Third Hokage did not know Medical Ninjutsu, he could clearly sense the stable, gentle Yang Release Chakra within the scroll.

"Shiraha, how long can this Medical Scroll be preserved at most?"

Tsunade quickly raised the crucial question.

Although the Medical Scroll had been successfully invented, its value would be greatly reduced if its storage time was too short.

Everyone clearly understood what Tsunade meant and looked at Shiraha.

"More than three months shouldn't be a problem, I think?" Shiraha did not overstate it. "The scroll I used just now was successfully made two and a half months ago. When I opened it earlier, only a tiny amount of chakra had been lost."

"Three months!" Tsunade was startled.

If that was the case, then this Medical Scroll was a strategic resource!

Most importantly, she had watched Shiraha's entire process of making it.

Without a doubt, for Medical Ninja with a certain level of skill, making this scroll was not especially difficult.

"How did you think of combining basic Sealing Jutsu with Medical Ninjutsu?"

Tsunade asked curiously.

"I have Tsunade-sensei to thank for that!" Shiraha said with a smile. "You all gave me the inspiration."

"Me? But all the experimental data I left behind were failures.

And yet you thought of using the most basic Sealing Jutsu!

Shiraha, you really are a genius!"

Tsunade excitedly pulled Shiraha into an embrace, giving him a faceful of cleavage.

"Mmgh, mmgh!" Shiraha felt himself struggling to breathe and immediately began to squirm.

In truth, ever since he had begun learning to make Demonic items four years ago, he had wondered whether he could seal Ninjutsu into scrolls just as he did with Demonic items.

Shiraha had conducted many experiments, all of which ended in failure.

Later, he discovered that the Medical Corps had conducted similar attempts years earlier.

Tsunade had proposed combining Medical Ninjutsu with Sealing Jutsu, but she was not skilled in Sealing Jutsu.

If the Sealing Jutsu was too advanced, ordinary Medical Ninja would not be able to learn it. In that case, mass-producing Medical Scrolls would be out of the question.

As for Nonō, she had tried several kinds of Sealing Jutsu, but they had all failed as well.

The reason Shiraha had succeeded was not only because of the experience of those before him and the inspiration he had gained from making Demonic items. The most crucial factor was the Eye of Truth.

He could use the quantified amounts of chakra to adjust the chakra ratio between the basic Sealing Jutsu and Medical Ninjutsu.

After roughly a hundred experiments, he finally succeeded in one go.

However, Shiraha subsequently repeated the experiment many times and made further improvements. Only after confirming everything was correct did he prepare to share the result with Tsunade and offer it to the village.

After all, if Konoha lost the war or the situation turned unfavorable, he would eventually suffer for it as well.

The more outstanding Shiraha's talent in Medical Ninjutsu appeared, the more easily he could obtain Hashirama cells. That was his ultimate goal.

Of course, research and experimentation were also among the joys of life for him.

Not only did he not find them tedious or boring, he thoroughly enjoyed them.

"Tsunade, wait a moment." Utatane Koharu could not help interrupting. "Shiraha, according to what you mean, making Medical Scrolls is not difficult? They can soon be widely adopted by the Medical Corps. Is that correct?"

"Whew..."

After Tsunade released him, Shiraha took a deep breath of fresh air and nodded.

"Yes, Lord Koharu, the process is not only not difficult, it is very simple.

You only need a certain level of Medical Ninjutsu and mastery of the most basic Sealing Jutsu.

The only slightly troublesome part of the process is outputting chakra according to a specific ratio."

Very simple?

Only slightly troublesome?

This must be what difficulty looked like through a genius's eyes!

"..." Shiraha's words plunged the Medical Ninja into silence.

"..."

Seeing the Medical Ninja's expressions, the higher-ups also fell silent.

If they were only learning the most basic Sealing Jutsu, perhaps they would not need particularly strong Yin Release talent, but they would certainly need extremely precise chakra control. That was not difficult for Medical Ninja.

However, making Yin Release and Yang Release Chakra coexist in a specific ratio was absolutely not merely "slightly troublesome," as Shiraha had claimed.

Still, among the Medical Corps, there were a certain number of Medical Ninja who could learn the combination of basic Sealing Jutsu and basic Healing Jutsu.

That meant that even if these Medical Scrolls could not be distributed to everyone, they could still meet the needs of Jōnin.

Most importantly, the genius who had invented the Medical Scroll before their eyes was only twelve years old.

Shiraha had invented Medical Scrolls in just a few years. In the future, he might very well be able to create improved versions.

It was not impossible that his future attainments in Medical Ninjutsu would far surpass Tsunade's, allowing him to produce even more inventions.
