Chapter 34

But he was afraid Tsunade would make a scene and smash up **, so he had no choice but to summon a Root ninja and order him to go to ** in advance, explain the situation, and give them a heads-up.

A little after three in the afternoon,

Tsunade finally walked out of **.

"Fuck! My luck was unbelievably bad today!"

"And a million ryo was way too easy to lose! It was all gone before two hours were even up! I should've demanded more money from Danzo back then. What fucking rotten luck!"

Cursing all the way, she eventually arrived at Kushina's doorstep.

Once inside, she grabbed Uchiha Yan and told him everything that had happened at the Hokage Office regarding the Medical Talisman.

"Don't take it to heart. I already did everything I could to secure those terms for you."

After saying that, Tsunade added,

"I know. This is a pretty good outcome."

Uchiha Yan nodded indifferently. "I expected this from the moment I started planning to make this thing."

"No village would just stand by and watch something capable of changing the balance of war remain solely in one person's hands, beyond their reach."

"I'm already satisfied with getting a chance to learn ninjutsu from the Book of Seals."

Besides, he already had more than enough ways to make money.

The more Uchiha Yan thought about the Medical Talisman technique in his hands, the more worthwhile this deal seemed.

If he kept it, at most he could gain some privileges for the Uchiha and earn a little money. But in exchange, the entire village would become jealous and suppress them, while the Uchiha themselves would be targeted even more harshly.

It was better to hand it over to the village in exchange for tangible benefits.

He had long had his eye on the Flying Raijin Technique in the Book of Seals. Given his Uchiha background, he could forget about ever touching that thing through normal channels.

Now, the opportunity had landed right in his lap.

To be honest, creating the Medical Talisman had only been a whim at first.

But after thinking it over, he had gained plenty from it—Tsunade's approval, the chance to study sealing techniques, an opportunity to build a connection with Kushina, and now, the Flying Raijin Technique as well.

This deal had been a huge profit.

Besides, the experience of making Medical Talismans would become the foundation for developing other ninjutsu talismans in the future.

As for those, he had no intention of handing them over again.

"You've suffered for this!"

Tsunade reached out and rubbed his head, a hint of pride in her voice. "I'm in a good mood today, and since you're studying sealing techniques anyway, I'll teach you something special."

Before Uchiha Yan could speak, Kushina cut in first. Tilting her head, she guessed, "A sealing technique? What is there that I can't teach? Could it be the Yin Seal?"

Tsunade snapped her fingers.

"Correct! It's the Yin Seal!"

Uchiha Yan immediately looked up and stared at the mark on Tsunade's forehead. "The seal on your forehead, Tsunade?"

Of course, he knew what the Yin Seal was—just information from his previous life. Now he had to pretend this was his first time hearing about it.

"That's right."

Tsunade touched the mark on her forehead and nodded. She pulled a scroll from her robes and handed it to him. "Here. Read it yourself first, and ask me immediately if there's anything you don't understand."

She paused, her tone turning serious. "I know your talent is monstrous, but this technique is dangerous. It concerns the spiritual sea in the forehead, and there can't be the slightest mistake. Don't mess around on your own."

"Tch—"

Kushina pouted. "I have a Yin Seal scroll too."

Tsunade directly poked her puffed-up cheek and added with a smile, "But you don't know how to use it."

Kushina choked on her words and huffed unhappily. "Sorry for not knowing it! I'm only young, so my spiritual power isn't strong enough and my will isn't firm enough. Besides, I don't need it yet."

In truth, she was anxious too. She wanted to master the Yin Seal as soon as possible.

However, its chakra storage function was not that important to her—the Uzumaki Clan's chakra reserves were so vast that she did not need to worry about that at all.

What Kushina truly cared about was the Yin Seal's strange effect of almost preserving one's youth forever.

Still, she was a little worried. "Xuan is only three. Is it really okay for him to learn this?"

Tsunade waved dismissively. "Relax!"

"If he can't learn it, then no one in the entire Ninja World can."

"Don't let his age fool you. His spiritual power is absurdly strong. Even I have to admit defeat."

To be honest, Tsunade was also quite puzzled by how Xuan's spiritual power could be so abnormal.

Both in quantity and quality, it far surpassed that of ordinary people.

But she had never asked.

Who didn't have their own **secret?

"Really?"

After hearing that, Kushina looked at Uchiha Yan beside her in surprise, her voice full of envy. "You're really incredible!"

"Hehe."

Uchiha Yan smiled at her and immediately reassured her. "Don't worry. Once I've learned this technique, I'll try improving it and see if I can lower the requirements for training it."

He did not think it was an impossible dream.

"Huh? Really? Can you do that?"

Kushina's eyes lit up at once.

Tsunade also leaned closer curiously. "You're not just bragging, are you?"

"There shouldn't be much of a problem. Just give me some time. We'll talk after I finish learning all the sealing techniques."

Uchiha Yan shrugged.

To be honest, he had long been interested in the Yin Seal.

He had been wondering how to get it from Tsunade.

He had not expected to obtain it so easily this time.

It seemed that developing the Medical Talisman and throwing out this bait had been the right move.

There had not been many details about the Yin Seal in the anime from his previous life.

But Uchiha Yan had long formed his own theory.

He released the scroll's seal, spread it open, and carefully read through it.

With his photographic memory and abnormal spiritual power, it did not take him long to finish reading it.

He had already worked out most of it in his mind.

Just as I thought. This thing is connected to the spiritual sea. Put simply, it concerns the upper dantian. It takes a different path, using spatial sealing techniques to open up the spiritual sea.

Whoever created this technique was definitely a genius.

Uchiha Yan secretly marveled.

Since it involved the spiritual sea, he did not dare act recklessly.

He decided to first thoroughly learn every sealing technique from Kushina before returning to tackle the Yin Seal.

When the time came, he intended to use this technique as a springboard and combine it with his Spirit Refining Method to deduce a truly complete method for opening the upper dantian.

Otherwise, it would be far too wasteful of his potential and intellect.

When it came to matters involving the spiritual sea, no amount of caution was excessive.

"Can you understand it? Is there anything you're stuck on?"

Tsunade asked curiously.

She also wanted to see whether this technique could truly stump Uchiha Yan.

"It's alright. There's a lot of profound sealing knowledge hidden inside. I plan to finish learning sealing techniques first, then come back and study it in depth."

Uchiha Yan immediately replied.

"Alright, I understand." Tsunade nodded. "This technique carries quite a bit of risk when practiced, so it's good that you're being careful."

She yawned. "You two keep studying. I'm heading out first. I've been so busy all day that my feet haven't touched the ground."

After saying that, she stretched lazily, her upper-body curves especially prominent as she rose.

Then she left and returned to her own courtyard.

Over the next dozen or so days, Uchiha Yan went to Kushina's place every day on time to study sealing techniques.

The elder and the child studied together, and their relationship grew rapidly.

To put it bluntly, they were both the type to judge by looks, each coveting the other's appearance.

During that time, Mikoto heard that Xuan was learning sealing techniques from Kushina and came along several times as well.

The Anbu and Root ninjas hidden in the shadows saw all of this, but the Third Hokage and Danzo had already given their orders, so no one interfered.

[...Your Four Black Mist Formation has reached its limit.]

[...Your Four Violet Flames Formation has also reached completion.]

[...The Four Red Yang Formation is likewise maxed out.]

[...You have fully comprehended the Sealing Barrier Technique and even tinkered out a version 2.0 of the Sealing Barrier Technique.]
