Chihiro has always known that the line between life and death in the ninja world is blurred, so when she learned that her grandfather was going to die, she didn't feel too sad, and only left a shadow clone to accompany her, perhaps subconsciously feeling that one day, she could break that boundary.

Now that he came to Huangquan by chance, he saw so many dead people and learned many secrets, which made him see the boundary between life and death more and more lightly.

Time, it was already the twenty-third day that Chihiro came to Huangquan.

Today, the shadow clone he left in Konoha to accompany the old man has dissipated, which also means that the old man has passed away.

A large number of memories appeared in Chihiro's mind out of thin air.

All the experiences of the shadow clone in the past month are known to Chihiro in every detail.

From memory, Chihiro learned that Orochimaru did not return to Konoha during this time.

So when the old man died, he didn't know about Chihiro's body.

Chihiro's feelings were very subtle, and she thought to herself, how would the old man feel if he knew that his grandson had actually come to the underworld one step ahead of him?

Chihiro suddenly couldn't help but laugh, and the smile was a little strange.

"Smack~"

"Ahhh~"

Some grumpy people always like to do it first and then move it.

For example, the whirlpool bamboo language.

"What are you laughing at, little ghost, you can still laugh?"

Uzumaki Take's tone was in a hurry, and another slap was on top of Chihiro's head.

"Smack~"

"Ahhh~"

"It's been more than 20 days, and you've only memorized more than 70 runes, how do you have a long brain, you can't remember five a day, and you're still embarrassed to laugh?"

"Hey, hey, hey, reasonable, Grandma Mito said that I remembered very quickly, and said that many Uzumaki people don't have my ......"

"Smack~"

"Ahh......h

"Okay, okay, you dare to talk back, right, even if you're about to do something, then can't you hurry up, day by day, do you know how tired I am, isn't it for your good, you are worthy of me working so hard... Balabala......"

“……”

Chihiro understood, most of the words of Uzumaki Bamboo were said by her former teacher when she was educating her.

So this man is revenge in disguise.

Chihiro chooses to shut up.

Let her play.

And so it was, and fifteen more days passed.

Chihiro has finally learned the basic runes of the sealing technique.

It is also the most complete one hundred and eight sealing runes in the entire ninja world.

Thirty-six Tiangang runes.

Seventy-two earth-shattering runes.

It is supplemented by the 12 earthly mudras.

It's the most complete foundation of sealing.

It is also the basis of the real 'divine arts'.

In the original book, there are many appearances of the sealing technique, and it seems that as long as it is a character, it can be used to seal the whole hand, but the description of the sealing technique has been vague.

How does it work?

What are the nature of chakra?

What is the difference between it and ordinary ninjutsu?

Why should those procedures be separately classified as sealing?

What exactly is sealing?

Also When did sealing first appear?

Chihiro had just crossed the time of birth, and because she was a baby, she could only eat, sleep and sleep every day, so she used that time to think about these questions.

Including so many forbidden techniques in Konoha, are they really all developed by the second generation on their own?

Also, the two of them reached the sixth level at the age of sixteen, but the real growth time actually started at the age of twelve, that is, it only took four years to transform from ordinary lower ninja to six lower ninja...... Is this reasonable?

If she hadn't traveled to this world, Chihiro wouldn't have had enough to think about these issues.

It's good to look at it as a setting.

At most, it's nothing more than a few complaints:

"It's a lot of fun."

"Tsk, how come the setting of the sealing technique is all elements of Huaxia Taoism."

"Ha, the protagonist really deserves to be criticized."

"It's a legend of the eyes!"

Yunyun.

But when Chihiro is really in this world, these so-called settings, the so-called hanging, the so-called blood relay and pupil techniques, as well as all kinds of mysterious forbidden techniques and secret techniques...... All things that are not reasonable become problems of careful consideration.

He could no longer look at these issues in a set light.

Because he crosses over, it proves that the world is real, and as long as it is real, then everything must be reasonable.

If it is unreasonable, it only proves that behind these seemingly unreasonable things, there must be secrets that can make it reasonable.

For example, sealing.

In the entire Hokage, the most powerful power is undoubtedly the sealing technique, such as sealing Kaguya, sealing the tailed beast, sealing the chakra, and creating enchantments.

And the most commonly used techniques are actually seals, such as using scrolls to seal ninja tools, sealing ninjutsu, detonation charms, and so on.

It seems that every aspect of the ninja world involves sealing, but it is only mentioned in a superficial and deep way.

Even, just one 'mystery' is used to give an overview.

Obviously this is unreasonable.

In the previous life, Chihiro only thought that this was the original author's inability to justify himself, so he left a big hole that was not filled.

But in this life, the sealing technique has become an unavoidable puzzle.

Chihiro has been trying to understand for a long time.

People who know how to seal often cherish their brooms, and Chihiro has never had a chance to understand the mysteries.

Although the mysterious patterns on the family ninja knife are actually a kind of use of sealing, even the old man only knows it and doesn't know why.

Although the seal scroll left by the second generation did record the cultivation method of the ghoul ban, it only recorded some combinations of techniques, as well as the order of the techniques, the materials required, etc.

It's like a doctor's prescription, telling you how to grasp the medicine, how to decoction, how to eat, and what disease to cure.

But it is not explained what the origin of which herb is, what is the efficacy, why it is so grasped, so fried, so eaten, and why it will cure this disease.

But Chihiro doesn't want to know about that, his curiosity about sealing is fundamentally, he wants to learn medicine, not to be the medicine catcher.

According to Chihiro's understanding, it seems that the vast majority of those who know how to seal in the ninja world are medicine catchers who have obtained prescriptions.

Before going down to Yellow Spring, Chihiro even suspected that the Uzumaki clan was just a medicine catcher who had more prescriptions.

However, to his surprise, after coming here, he found out that the Vortex clan was really an old Chinese medicine doctor.

People really know how to heal!

No, I really know how to seal!

Those one hundred and eight runes are the Compendium of Materia Medica.

According to the ancestor of the Vortex Clan, the sealing technique they mastered, including the thirty-six runes of Tiangang, originated from the Heavenly Realm, High Heaven.

The seventy-two runes of the Earth Heist originate from the underworld and the human world.

To be more specific, the originator of the Vortex clan did not disclose, for example, how the runes were born and how he obtained them, after all, he said that he was from, not from.

Is it passed down by the Six Dao Immortals, or is it some other adventure......

He only said that the gods also use runes supplemented by divine power to drive divine power, and even become magic, that is, divine magic!

And the Vortex are the Terrans who have mastered the most sealing runes.

In addition, the originator of the whirlpool also bluntly said to Chihiro that the whirlpool clan in the human world actually only mastered the twenty Heavenly Gangs and the thirty Earth Demons, with a total of only fifty runes.

Only the Vortex Clan who came to Yellow Springs after death had the opportunity to learn all one hundred and eight runes.

As for the reason,

The originator was ashamed to say that on the one hand, because he died too young and too suddenly, he didn't have time to teach future generations everything he knew.

On the other hand, thirty-six of them in the underworld were also obtained after coming to the underworld.

Tut.

I have to say that this originator is a real pit.

If he could have taught all the runes he had mastered to future generations, the Vortex Clan would not have fallen into such a situation now.

However, it is also cheaper than Chihiro.

It was precisely because of this that he had the opportunity to learn these one hundred and eight runes.

Because, the reason why this originator is willing to let the clansmen give the runes to Chihiro is actually to let Chihiro return to the human world, and then transfer them to the orphans of the Uzumaki clan......
