Food gives me an entry, I will be invincible if I stay alive

Chapter 106: Numbers and Symbols, Various Wonderful Uses (7th Update)
The little hedgehog's bookcase looks ordinary.

The shape and appearance were clearly a smaller version of an ordinary bookcase, but the little hedgehog now deliberately mentioned it, and Chen Xu carefully sensed it again, and suddenly found that this bookcase seemed to have its own pure aura.

No, it should not be called pure air.

It is more like an invisible and traceless, yet heavy and vast aura.

Chen Xu could sense this breath for a moment, and wanted to capture it more clearly, but then he found that he could not sense it. He only felt that it carried an inexplicable power and was very mysterious.

So, what is this?
Is it literary spirit or literary fortune?

Chen Xu was slightly surprised. A little hedgehog monster carrying a "Wenyun" bookcase?
Wei Yuan noticed Chen Xu's gaze, and immediately straightened his chest and said proudly: "This is what my teacher left for me. My teacher said that with this bookcase, my evil spirit will not dissipate.

I continued to study and practice, and all the magical powers I gained were pure energy. After a long time, I was able to shed my demon body and transform into a human form.

By then, I will be a demon fairy!"

When Chen Xu heard this, he immediately thought that the little hedgehog's teacher was probably also a powerful scholar in the world.

I just don’t know what kind of senior would actually accept a little hedgehog as a student in the mountains?
This is quite interesting. Chen Xu pondered for a moment and reminded him, "Friend Wei, your teacher only taught you to study hard and practice, but never told you that people's hearts are treacherous?"

Wei Yuan's soft hair suddenly stood up again, and he looked at Chen Xu warily: "W-What do you mean? What are you going to do?"

Look, isn't this still quite vigilant?
It is sometimes vigilant and sometimes careless, and I don't know whether it is confused or smart.

Chen Xu laughed and said, "What I mean is that you shouldn't tell anyone, demon, ghost... no matter what kind of living or dead spirit it is, anything with emotions, you shouldn't tell it.

Your bookcase is a treasure, and in our world, there is a famous saying that goes, "A man is innocent until he is found guilty of possessing a treasure!"

The little hedgehog suddenly jumped up from the table, ran to the edge of the table and looked at Chen Xu warily.

"You, you... you can't take my bookcase away from me. My teacher said that the bookcase is my spirit, and I am the spirit of the bookcase. We are one, and no one can take it away from me."

Chen Xu: "I won't snatch it. If I did, why would I remind you?"

"Ah, yes." The little hedgehog reacted immediately and a look of shame appeared on his face.

Then, it hesitantly moved closer from the edge of the table, bowed to Chen Xu and said, "I am a little demon, and I would like to apologize to you, fellow Taoist.

Fellow Daoist, I, I came here not only to inform you of the news, but also to ask for a favor.

The little hedgehog finally revealed his true purpose and told the real purpose of his visit.

Chen Xu: "Fellow Daoist, please speak."

"I, I, I..." The little hedgehog blushed, "I've been studying for many years, but since my teacher left, I haven't been able to understand the books for a long time."

Can't understand the book?

What does this mean?
Chen Xu stared at the little demon in front of him and signaled it with his eyes to continue.

Wei Yuan said stubbornly, "That's right, without a teacher to explain, I can hardly understand many books.

I heard that you are very good at studying. Those evil spirits said that you can make moths ring bells. You must be one of the smartest people of our time.

I, I want you to teach me..."

The more he spoke, the lower Wei Yuan's voice became.

He felt ashamed when he talked about it later.

It hurriedly put down the bookcase behind it and started rummaging through it.

One, two, three... five books were taken out in succession.

The originally miniature book turned into normal size once it fell on the table.

After the little hedgehog finished taking out the books, he put the bookcase back on his back and said hurriedly, "My teacher said that these books of mine are classics that are hard to find outside. Fellow Chen Dao, please take a look.

I'll read with you, this is... my reward, is that okay?"

It stood on the table, clasped its hands, and said, "But this cannot be taken as a gift, because I can only have one teacher, my teacher."

Chen Xu smiled and flipped through the five books that the little hedgehog took out one by one.

Then, Chen Xu's expression gradually became solemn.

Among the books that the little hedgehog took out, two were on arithmetic, one was "Shangshu", and the other was "I Ching".

There is one last book, and the last book is actually "Talisman".

Chen Xu had the book of "Talisman" in his hand and had just opened it when he suddenly felt a slight dizziness in front of his eyes.

Before he could fully understand the contents of the book, a large number of hazy and strange lines appeared in Chen Xu's field of vision.

These lines are twisted and entangled, clearly difficult to understand.

But when Chen Xu saw it, he felt as if something subtle was touched in his soul.

He saw one of the lines jump out and turn into a tiny flame in the vast void.

Chen Xu's hand moved subconsciously and he closed the book of "Talisman" in an instant.

All the strange lines before his eyes disappeared, but the column about fire control on the panel of his Shi Ding Tian Shu had changed.

[Fire Control (Level 2 139/1000) Fire Condensing 0.1%]

Subtle insights into fire flooded into his mind. Chen Xu felt that he could definitely grab a fire out of thin air even if he just moved his mind slightly.

This is different from his previous fire control!

To control fire, one must first mobilize the innate Qi.

Now, it seems that he can sense and control the subtle "fire energy" between heaven and earth around him out of thin air.

The Talisman Book that the little hedgehog had taken out seemed composed entirely of messy lines, but it actually contained the supreme principles of all things in the universe. "Fellow Daoist Chen," the little hedgehog's curious voice echoed, "What do you see? Do you understand this Talisman Book?"

Chen Xu calmed himself down and looked back at what was in front of him.

Moonlight streamed into the simple room, revealing five books on the table, all with clear covers.

Only the book "Talisman" had words that seemed a little blurry.

Chen Xu picked up the book and opened it again, but this time no strange visions appeared.

There was only one sentence on the title page: "Talisman is the command of heaven and earth."

Runes are the medium through which living beings control the world!
It was just a simple sentence, but it actually made people's hearts surge with excitement at the first sight.

Chen Xu flipped through the pages again, and wow, what appeared on the second page was not some mysterious rune, but a mathematical problem about measuring the angle between the sun's shadow and the ground.

The little hedgehog looked at Chen Xu expectantly and said, "Friend Chen, my teacher once said that if someone can understand this book,
When you open the book of "Talisman" for the first time, you may get magical benefits.

Did you get it?

Only then did Chen Xu understand that the vision he had just received came from this.

He thought it was amazing and replied to the little hedgehog, "I learned a fire trick."

"Fire!" The little demon shuddered and said hurriedly, "I'm afraid of fire!"

It was as if it was afraid that Chen Xu would show it a fire technique on the spot.

Chen Xu couldn't help laughing.

He asked Wei Yuan: "You asked me to teach you how to read. Here are five books. Which one do you want to read first?"

Wei Yuan swept his eyes across the five books, and his gaze quickly moved away from the book of "Talismans", with a frightened expression on his face.

It gritted its teeth, and finally pushed the Book of Shang in front of Chen Xu. Then it stood up, saluted, and said, "I beg you to teach me the Book of Shang first."

Alas, I can’t understand the book of “Taoism”, I’m afraid of arithmetic, and the “Book of Changes” is even more terrifying…

Forget it, I’ll just continue studying the Book of Documents.

Wei Yuan explained to Chen Xu: "My teacher once said that reading should be done step by step, from easy to difficult. The Book of Shang is very good!"

Chen Xu smiled.

So he lit the lamp, and in this moonlit night, he taught a little hedgehog demon to read "The Book of Documents".

In between assigning passages for Xiao Yao to recite, Chen Xu would occasionally flip through the book "Talisman".

I found that in addition to the sun shadow measurement questions on the second page, there are also questions such as terrace area calculation, dam earthwork estimation, etc.

If you think about it carefully, these should all be classified into elementary geometry categories.

After that, there are "turtle legs", which are geometry problems of triangular pyramids.

There is also "Yang Ma", which is also a kind of solid geometry, but it is more complicated than the previous part.

There are many geometric shapes that are not listed one by one. In short, the first half of the book "Fu" seems to be dedicated to developing the reader's spatial imagination.

When the topological figures gradually appeared in the second half, Chen Xu frowned.

Later on, a graphic symbol suddenly popped up on one page.

This is a strange symbol that looks flat at first glance, but is three-dimensional when you look closely.

Chen Xu looked carefully and suddenly felt that the symbols in front of him seemed to be flowing.

In a trance, it changed from two dimensions to three dimensions, and then from three dimensions to five dimensions. Finally, this symbol reflected two words in Chen Xu's mind: avoid water!

Chen Xu's heart skipped a beat. He looked again carefully and saw that the words "avoid water" had disappeared. The symbol on the paper was still that flat symbol.

But the word "avoid water" kept lingering in Chen Xu's mind, and he had a vague understanding.

A joy of "knowing something" arises from the bottom of my heart.

This book of "Talismans" is truly a book of talismans, not a book of numerology!

Runes, is this what they are like?
In fact, up to this moment, Chen Xu's understanding of runes is still vague, he knows what they are but doesn't know why.

But this vague understanding seemed to make him know how to use basic runes.

With joy, he patiently helped the little demon Wei Yuan interpret the "Book of Documents".

The little hedgehog felt dizzy from reading, and suddenly he yawned, and his whole body suddenly stood up straight.

"Fellow Daoist Chen, I, I..." It widened its small green eyes.

Chen Xu said: "If you are tired, you can go back and rest. It is not advisable to read too much every day."

The little hedgehog's face was red, and all the soft hair on its head stood up, like a bunch of small swords pointing at its head.

It hurriedly took away all the books, then bowed to Chen Xu and said, "Thank you for your guidance, Fellow Daoist Chen. I, I... I won't come tomorrow. I'll come after you finish the Daoist Academy Examination.

Fellow Daoists, be sure to watch out for the evil spirits on Mount Pufeng. They will disguise themselves as human beings and go into people's homes to eat them."

After Wei Yuan gave Chen Xu repeated instructions and got Chen Xu's promise to be careful, he jumped out of the second-floor window of the inn.

Chen Xu walked to the window and saw that the little hedgehog demon had just landed on the ground when its entire body whooshed into the ground and disappeared.

It turns out that this little demon can actually use the earth escape technique.
