Chapter 42

Flash Step was developed by borrowing the concept of Flash Step from the world of the Shinigami and building it on the foundation of the Body Flicker Technique.

It was definitely different from the genuine version from that world, but it was more than powerful enough.

Speed was the ultimate truth.

For ninja, the Body Flicker Technique was far too important.

Hadn't Shisui Uchiha earned the title "Body Flicker Shisui" through that absurdly powerful Body Flicker Technique of his?

Shave was based on Shave from the pirate world, combined with the Body Flicker. It was good too. But anyone without strong taijutsu or sufficient physical strength could forget about learning it.

It was too hard on the legs.

Moon Step was about the same.

As for Explosive Flash Step?

It was an ultra-high-burst movement technique. Even Yan himself did not dare practice it yet.

It could kill people.

"Not just Explosive Flash Step—even Shave and Moon Step aren't suitable for my current physical strength. I'm too young and still growing, so I need to improve my physical strength further. For now, I'll focus on Flash Step."

"With the foundation of the Monster Strength Technique, it'll be easy to master."

Uchiha Yan considered it for a moment, then began practicing Flash Step on the spot.

It only took around ten minutes.

[You practiced Flash Step. With a solid foundation and high comprehension, you progressed rapidly. Flash Step has reached perfection.]

That day, just as Uchiha Yan had mastered Flash Step, Tsunade came knocking and interrupted his training.

"You brat haven't been holed up at home practicing ninjutsu these past few days, have you?"

"You disappeared for days at a time. I thought something had happened to you."

With her arms crossed, Tsunade leaned against a pillar and watched Uchiha Yan practicing Flash Step nearby before finally speaking.

"Your speed is seriously frightening. Don't tell me you even modified the Body Flicker Technique?"

She had noticed something, and immediately pressed further.

"More or less."

Uchiha Yan stopped, nodded, walked over to grab a towel from a chair, and wiped away his sweat. He casually asked, "Teacher, did you come here for something? You didn't come all this way just to watch me train, did you? Or are you out of alcohol again?"

He knew Tsunade's personality too well. If there was no real business, she could not be bothered to make the trip.

"What do you take your teacher for? A drunk?"

Tsunade rolled her eyes at him irritably.

Uchiha Yan was speechless.

Did she have no idea whether she was a drunk herself?

She could not go a single meal without alcohol. That was exactly who she was.

"Get to the point. If not, I'm getting back to training."

Uchiha Yan urged her.

Hearing that, Tsunade stopped making small talk and got straight to it. "Isn't it because the old man is pushing for progress on the Medical Talismans? You hadn't come looking for me in days, so he got anxious. He was afraid you were dragging your feet."

"I also wanted to ask: have you finished the Medical Talismans? Can they be mass-produced?"

"If they can, hurry up and get them made."

"The front lines have already started fighting Sunagakure. I figure I'll have to head out there soon too."

There was no helping it. Their opponent was Sunagakure, so she had no choice but to go.

Without her, no one else could handle Chiyo's poison.

She and Chiyo could be considered old rivals.

"Oh, it's done. Wait a moment."

After hearing that, Uchiha Yan nodded and waved a hand.

Then he turned and went inside to retrieve a scroll. Handing it to Tsunade, he explained, "The complete technique is in here. However, only medical ninja who know the Mystical Palm Technique can make them."

"Of course, I also considered that medical ninja might not necessarily understand Sealing Jutsu, so I divided the process into two parts."

"First, have ninja proficient in Sealing Jutsu make Blank Medical Talismans. Then have medical ninja who know the Mystical Palm Technique inject Mystical Palm Technique chakra into them."

He was worried that the Third Hokage and the others would keep pestering him with questions, so he had simply resolved every possible issue at once.

In truth, he still had the Second-Generation and Third-Generation Medical Talismans.

The Second-Generation Medical Talisman did not require the Mystical Palm Technique. Any ninja could make it using specially made blank scrolls.

That was because Uchiha Yan had directly embedded the Mystical Palm Technique Formula into the Blank Medical Talisman's Formula.

Yes, he had compiled the Mystical Palm Technique into a Formula.

It was an extraordinary breakthrough. It meant that in the future, he could transform most ninjutsu into Sealing Jutsu and mass-produce them as talismans.

As for the Third-Generation Medical Talisman, it was even more formidable.

He had directly created a fully automated production line for Medical Talismans.

The moment Tsunade left, Uchiha Yan withdrew his gaze.

As long as there was enough chakra and specially made paper, Medical Talismans could be produced batch after batch.

He had no intention of revealing the latter two generations of technology yet.

For now, it was perfectly fine for him to use them quietly himself.

Unless the entire Konoha—or even the entire Ninja World—one day took the Uchiha name, he would only then consider bringing them out into the light.

Naturally, Tsunade could not guess at all the twists and turns in his mind.

The First-Generation Medical Talisman technology alone had already left her dumbfounded.

As she flipped through the scroll, she clicked her tongue repeatedly. "Not bad, you even thought of this!"

"Sealing Jutsu can be used like this? You really are something!"

"With this, mass production won't be a problem at all!"

"Although there aren't many medical ninja who can use the Mystical Palm Technique, there are still a few."

"If we put some effort into training more, gathering enough people in the short term won't be a problem."

"I won't hold you up any longer. I'm off!"

Tsunade waved the scroll in her hand and turned to leave.

"Wait!"

Uchiha Yan hurriedly called out to her, then added unhurriedly, "Haven't you always wanted to expand the Medical Team? This is the perfect opportunity."

"You can use the need to train more people capable of using the Mystical Palm Technique as a reason to approach the Third Hokage. He'll be much more likely to agree."

"Oh, and don't forget to bring back the Flying Raijin Technique for me. I've had my eye on that thing for a long time."

He knew very well that expanding the number of medical ninja and reducing casualties at the front lines had been Tsunade's obsession for years.

Giving her a little push had no downside.

"Mm, you've really reminded me. I understand now, hehe!"

As soon as Tsunade finished speaking, she leaned over and pulled him into her arms, squeezing him so hard that Uchiha Yan nearly could not breathe. After letting go, she casually ruffled his head, messing up his hair completely, then finally turned and left in satisfaction.

When she reached the door, she waved a hand without looking back. "Leave the Flying Raijin to me. Just wait for it."

In the Hokage Office, the smell of smoke had yet to fully dissipate.

Tsunade dropped the scroll onto the desk, crossed her arms, and said to the Third Hokage, "There, all the Medical Talisman stuff is in here. Old man, don't play dumb about what you promised."

"Of course!"

The Third Hokage took the scroll and quickly skimmed through it. Once he had a general understanding, he nodded and said, "Has that kid Yan chosen his ninjutsu yet? Why didn't you bring him along?"

"I wanted to thank our great contributor properly in person."

With Konoha currently locked in fierce battle with Sunagakure, these Medical Talismans had arrived like timely snow.

"Him? He's buried himself in training and can't pull himself out. He couldn't be bothered to come over. Just let me bring it back for him. Give me a training scroll for the Flying Raijin Technique directly."

Tsunade explained casually.

"I see..."

The Third Hokage looked somewhat regretful, but he still nodded.

Originally, the Third Hokage had wanted to use this chance to get closer to Uchiha Yan and win him over properly.

But with the war growing increasingly tense, he was so busy his head was about to smoke. He simply had no time to go talk with him.

Still, he understood that Uchiha Yan was a research fanatic and a training maniac. Though young, he was as steady as a rock.

It was not strange at all for such words to come from him.

Even so, he could not help adding, "Why the Flying Raijin Technique of all things? Was that your idea? Did you make it clear to him just how difficult that technique is to learn?"

"Look, from the Second Hokage until now, only two people have truly mastered Flying Raijin. Even Minato has only just grasped the basics."
