Wei Gong found a relatively new blue book in the corner, which was Yue Chuanwo's "Introduction to the Soul and the Speculation of the Principle of the Qiankun Mirror".

The title is strange because, judging by the title, it seems that the author himself is fraught with great uncertainty.

However, it can be roughly seen from the content that Yue Chuanwo had already created the prototype of the Qiankun Mirror at that time-

A portable device that can be used to transmit data and perform various image and sound processing, and even has a certain collection function.

Emiya felt that he didn't call this thing a mobile phone, and he was already very worthy of this era.

The advent of the electronic information age has led to the decline of paper media and books.

Similarly, Yue Chuanwo's soul research led to the advent of the Qiankun Mirror, which led to the same thing happening in this world.

This is a historical necessity.

It's just that Wei Gong still hasn't figured out what the specific operation principle is, and how he found out.

He sat on the desk with Jian Rin Sakura, the other party was holding a book [Sailing on the treacherous sea of imperial power and rule], and he was holding Yue Chuanwo's book.

Each sat down on the bench and looked at it gently.

Occasionally, there is the sound of the pages turning.

This feeling made Emiya feel like he was back in college.

Turning to Yue Chuanwo's book, a part of it was drawn about the structure of the Qiankun mirror, but it was not written what the materials were for its creation.

It seems that this part, for the Heavenly Sword Kingdom, is a supreme secret.

However, this does not prevent Emiya from understanding the principles of communication and imaging in the text.

Similar to the function of modern mobile phones, the Qiankun mirror is also divided into several parts: processor, display screen, shrink storage unit, information transmission system and projector.

The next 100 pages or so are devoted to how it works and how to use it.

Emiya smiled knowingly, and could probably imagine the confused look on Kenrin Sakura when she looked through the book.

He still has some knowledge, so he can probably understand some of it.

Imaging and processing are analogous to the current mobile phone structure, the difference is in the core soul principle, and the related means of transmission.

The original manifestation used above should be based on the material of soul excitation, and the transmission method, in Yue Chuanwo's way, is-

Soul interaction.

[In the realm of the unconscious soul, they store and exchange information in a peculiar way, I have no way of knowing what, and their transmission speed is even shorter than one billionth of a second, and I even suspect that information is transmitted instantaneously without delay.] And, the magic of it is that it is not disturbed by anything. Even in stormy weather, or in a closed metal cabin, it can be carried out smoothly. 】

Seeing this, Emiya pursed his lips and laughed again.

Because he saw a small note next to him, an essay written in black pen and ink -

[Master Yue Chuanwo's mention of the storm and the sealed metal box here must have his deep meaning, but I can't figure out why these things affect him, and why these two things are here, need to be studied more carefully. 】

The font is sharp and full of majesty.

Those who dare to leave an essay on this book will probably not be a person like Master Liu Dun.

Emiya guessed that it should be some member of the royal family.

"Hey, this handwriting ......"

It just so happened that Kenrin Sakura also saw the words on it.

"This is Qiu Xi's handwriting," she sneered, "I didn't expect this girl to be able to read such a difficult book, and she made notes on it." ”

"Her Royal Highness the Second Princess who looks at it this way should be quite smart?"

"Of course, she has not only cultivated to gain it, but has shown extraordinary intelligence since she was a child, and even the former emperor often praised her......" Speaking of this, Jian Rin Sakura suddenly stopped, and a hint of cunning appeared in her eyes.

"She's our pride, and you'll understand when you have the chance to meet her in the future."

Wei Gong nodded, and did not delve into the matter of Jian Qiuxi, but continued to read Yue Chuanwo's book.

Seeing his appearance, Jian Rin Sakura next to him was slightly stunned, then smiled with satisfaction, sat down in a chair, and continued reading.

Because the soul is unique, even if a person's Qiankun mirror is stolen, it is very safe, unless the internal identification system is destroyed, but in this way, the content stored in the Qiankun mirror is useless.

According to Yue Chuanwo's description in the book, for the sake of security and information preservation, the user's information will be stored in the soul storage station.

The exact location of this information center station is not mentioned in the book.

However, as for the storage methods that may cause huge trust panic in various countries, Yue Chuanwo marked it in the book like this-

[They, like the soul itself, are a realm that we cannot tread, and since the birth of the Qiankun Mirror, the storage station has existed in a ghostly way, and even if I want to, I can't tamper with the contents at will.

I don't even know where it fits in the world.

The Qiankun Mirror is not my creation, it is a creation of God, and it is only presented through my hands. 】

Seeing this, Wei Gong couldn't help but take a deep breath.

He didn't know.

Yue Chuanwo created the Qiankun Mirror, but he did not analyze the principle clearly.

Emiya flipped the book to the last page, and there were only a few short lines here—

The soul is unique.

The soul is individual. 】

At this point, Yue Chuanwo did not write any more, but ended with a question-

[If you want to explore the nature of the soul, then you must find out its basic composition, that is-

What is unique and cannot be reproduced.

At the same time, whether it can carry more individuals, such as a collection of souls.

If the soul is individual, then it makes the matter of which it is made even more peculiar.

So, I'm stuck in this puzzle, and I'm going to show it to you, hoping that someone wiser will be able to solve it. 】

At this point, the book is over.

Yes, compared to the information about the artificial intelligence that Cui Xiaoxiao obtained, the content given by Yue Chuanwo when he wrote this book will be more advanced.

This is probably his discussion in his early years when he created the Qiankun Mirror, and at the same time expressed his doubts.

And until the artificial intelligence was created, he uploaded his own memories and brain information, and he still had not solved the secrets.

The only discovery I made with Cui Xiaoxiao before was that in the core of the Qiankun Mirror, there was a core processor similar to that of a quantum computer, and the material used was the source stone he discovered at the beginning.

Seven Attribute Primordial Stones are gathered together to cause an explosion to produce the Celestial Source Stone, which can also change the user's attributes.

These magical properties are linked together, and there seems to be some great secret or law hidden.

I just don't know what it is.
