Heaven's Formula

Arithmetic classics are nothing more than a few books, such as "Nine Counting Books" which tells about some basic computing experience, and "Sunjing" which discusses various interesting arithmetic problems. No matter which one she reads well, even a few years ago He also wrote notes for Suanjing.

But this book is obviously different, not to mention the content, just the arrangement of the text is very strange-not written from top to bottom, but horizontally from left to right, and the descriptions are all colloquial words. It makes people feel that the author lacks cultural background.

She decided to put these aside first, and look at what the other party wrote.

However, Mo Yun was surprised to find that she couldn't understand the formula written on it!

Chapter 122 Book of Thoughts

Those are some ghostly symbols.

Counting chips are not like counting chips, and words are not like words. Can this kind of thing really be called arithmetic?

"Um... where did you get this book?"

"Xia Fan made it up, and he asked each of us to copy it." Ning Wanjun sighed, "It was easy at first, but every time I turn a page later, the problem becomes much more difficult. I suspect Is he deliberately playing tricks on everyone?"

Xia Fan?She was shocked, this name... Isn't it the person Qiuyue mentioned!

Playing tricks has always been the best thing for ignorant people.

"You may... have indeed been tricked by him." Mo Yun said in a low voice.

"Sure enough, I just said that arithmetic can't be like this!" Ning Wanjun slapped the table and said, "But if it's you, it must not be a problem, right? Why don't you tell me what the content behind is all about? Let him rewrite it!"

Wait, could it be that the princess understands the previous content?

By the way, she said it was easy at first.

Mo Yun turned to the first page and found that there was a prologue.And in this part, it turns out to be the elaboration and explanation of various strange symbols.

The most important thing to fool others is to blur words and use words to guide consciousness. This person actually writes out the vague parts, which is worth pondering.

Forget it, it would be convenient for her to find out the other party's flaws fundamentally.

Mo Yun decided to start from the beginning, and then defeated Xia Fan's disguise in one fell swoop.

"Wait for me for a quarter of an hour, let me read this book through first."

"No problem." Ning Wanjun said expectantly.

……

"Mo Yun."

"Mo Yun?"

"Hey, how are you?"

Mo Yun suddenly woke up from the book, she looked at the princess, and the latter was also looking at her with concern, "Who am I?"

"Ning Wanjun...His Royal Highness?"

"How much is this?" The other party pointed out another finger.

"One... no," Mo Yun shook her head, and she realized what the other party was doing, "I'm fine, why are you worried about this?"

"Because of... rumors. I'm just afraid that you're insane."

"What are you talking about—" Mo Yun smiled, "It's just reading a book, by the way, how long have I been reading it?"

She suddenly found that her neck was a little sore.

Ning Wanjun stared at her for a long time, "One hour."

an hour?Mo Yun blinked in surprise, had he been looking at it for so long!

"And you only read a dozen or so pages." Ning Wanjun put a basket containing dishes on the side of the table, "During dinner just now, I saw that you were reading seriously so I didn't bother you. I didn't expect that you I didn’t even change my posture, luckily I asked Qiuyue to prepare a copy for you.”

"Thanks, but I'm not hungry yet."

"As expected, you are still the same as before." Ning Wanjun shrugged, "That's why I don't want you to go out and hang out in the palace. Speaking of which, what do you think of this book?"

"How about this book—"

These words were like lightning, reconnecting Mo Yun's disconnected thoughts.

By the way, I was indulging in between the lines just now, and the reason why I was so forgetful was entirely because of this book—"It's incredible!"

"What does it mean to be unbelievable?" Ning Wanjun asked.

"This is definitely a wonderful book, and..." Mo Yun was a little stuck at this point, how could she describe the meaning of this book?It would be wrong to say that it is extremely profound and mysterious. After all, even Her Royal Highness can understand it, so it is destined to be a basic teaching book.But to say that it is the same as "Nine Counting Books", that is definitely not the case.

It has innovated a lot of unique vocabulary and symbols. Those weird "ghost symbols" are actually various numbers and calculation forms. It was quite difficult to adapt at first, but after a long time, you will find that they are extremely concise and clear. It is more convenient to get up.

But these are not the main points.

If this is the case, then it is only an improved "Nine Counting Book".

After pondering for a long time, she found a barely close word, "...thought."

"Thought?"

"The most precious thing about it is its thought—the meaning of this thought is not even limited to arithmetic!" Mo Yun took a deep breath, "If this book is spread outside, it will definitely cause a sensation."

Yes, it is thought.

It looks similar to "Nine Counting Books", and it also throws out many arithmetic calculation formulas and examples, but it is different from the latter's single isolated examples. A simple to obvious description, step by step to build a broad picture behind!

And everything starts with the phrase "there is and only one straight line passing through two points".

Five axioms.

Five postulates.

All subsequent content is based on these few short sentences.

Because the former is correct, the latter deduced from the former must also be correct—even if it seems unintuitive, but in the face of iron-like logic, it can only be admitted that it is true. This is the meaning of this book.

Mo Yun felt that a brand new door had been opened.

Everything she had learned in the past seemed fragmented and unsystematic compared to the content above.

She didn't expect arithmetic to be so beautiful and regular.

"Is it as exciting as you said...how can I not feel it?" Ning Wanjun muttered in a suspicious tone, "Forget it, you can stay here tonight and continue reading this book, but don't forget to eat .”

"I..." At this moment, Mo Yun suddenly wanted to remember why she came to Jinxia City, but she couldn't bear to put down the book in her hand for a while, so she couldn't help showing a dilemma.

Ning Wanjun smiled, and she sighed softly, "You really are the kind of person Xia Fan said is extremely talented."

"Why do you say that?" Mo Yun asked puzzled.

"When he gave this thing to us to transcribe, he once said a word - anyone who can't feel the beauty of the content in this book has no talent to become a great scholar. Although I don't know what the title of a great scholar is, it is obvious that You are entitled to it."

"Xia Fan, where is he now?"

"It should be in the residential area of ​​the alchemist. I forgot to tell you that he is a privy alchemist. He has been promoted to the fifth rank now, and he is working in the command department."

Mo Yun noticed that when the princess mentioned this person, her tone was full of complacency.

"Can I meet him?"

"Of course," Ning Wanjun replied, "I think he also wants to meet someone who can appreciate this book? By the way, this guy seems to know a little bit about everything. If you have any questions that have puzzled you for a long time, You might as well talk to him. Maybe he can give you some different advice."

How is it possible, the problem of the Ministry of Industry cannot be solved by a layman.

Although she thought so in her heart, Mo Yun didn't say it out loud, because she could feel that the other party had good intentions.So she just nodded slightly, "I will."

……

The next day, Ning Wanjun took her to the beach.

Mo Yun's eyes were a little swollen due to studying that incredible arithmetic handbook all night, but mentally, she didn't feel sleepy at all, and she even looked forward to continuing to light up the night battle after returning home.

It's just that she doesn't quite understand why Xia Fan, who is an alchemist of the Privy Council, stays in places like the seaside during the day.

After asking about the confusion in her heart, the princess laughed softly, "Because he is in charge of building a brand new salt field for me."

"Salt field?"

"Well, it looks like a rice field, but it produces sea salt." She pouted forward, "Look, we're here."

Chapter 123

After nearly a week of exposure to the sun, the experimental field has initially shown results.

Xia Fan stepped into the crystallization pool on the lowest floor with bare feet, and the warm seawater immediately submerged his insteps.Compared with the evaporation pond above, the seawater here is particularly turbid, covered with foam, and glaringly reflected below.

This reflection is not from sea water, but from a thin layer of white crystals at the bottom of the pool.

Eunuch Li couldn't help but bent down, poked the mud with his hand, and put it in his mouth, "Salty, so salty! This is really salt!"

Although I don't know why the salt grains can be soaked in water, but the bitter salty taste is indeed a unique feature of sea salt.To be honest, when Her Royal Highness took out a sum of money to implement Xia Fan's idea, he was still worried.It wasn't a matter of money. After all, most of the labor force was borne by His Royal Highness's troops, and the actual expenses were not too much. He was worried that if he failed, it would damage the prestige of His Highness the Princess.

Everyone trusts the princess, not the alchemist she finds—if Ning Wanjun fails because he trusts this person too much, then others will inevitably have suspicions that the princess doesn’t know who she is. This intangible thing is very difficult to make up for.

Now that Yantian has really exposed the salt, a huge rock in Eunuch Li's heart has finally been released.

He didn't understand the tricks involved, and he didn't want to understand, as long as there was salt in the salt pond, even if it was sprinkled by Xia Fan himself, it was better than failure.

As soon as the person is satisfied, even looking at Xia Fan's appearance is much more pleasing to the eye.

This guy... is pretty good.

"Xia Fan, why doesn't the salt melt?" Li lifted his tail and walked to Xia Fan in two light steps.

Xia Fan's gaze immediately shifted from the salt to the opponent's feet.

In the pool reflecting the blue sky and white clouds, a girl playing barefoot in the water faces her back and overlooks the sea, which is a perfect picture in itself.

What's so nice about salt.

Can it compare to the fox demon?

"Xia Fan?"

"Well, this..." Seeing the other party turn around, he quickly turned his eyes away, pretending to be serious, "Because water can't dissolve salt indefinitely. When its salt content reaches the upper limit, it doesn't matter if you add more salt to it." It will melt. This is also the principle of sun-dried salt and boiled salt-the less water, the less salt it can hold."

"But there's not much salt in the pond..."

"Indeed," Xia Fan replied carefully, "This pool is just for verification of craftsmanship. Its size is too small, and it is the first pool of salt. It is normal to have less."

In addition, he also found many problems.For example, the height of the evaporation pool and the crystallization pool can be lowered a lot, and it is best to complete a cycle in three days; another example is to rely on manual steps to pump water when the car is turned over. It is good to say that there are few pools. , it is best to get a more convenient pumping device and so on.

But the pool has proven that it works, and that's arguably the most important thing.

Li stepped on the pond twice curiously, "Then how will the salt be collected from now on?"

"It's very simple, just like drying millet." Xia Fan smiled, "When it accumulates a lot, just use a wooden shovel to shovel it all the way."

The piles of white "salt mountains" piled up in the pool have always been the most spectacular scenery in the salt field.

"Xia Fan, come here!" Suddenly, Ning Wanjun's voice came from behind.

People around bowed their heads and said, "I have seen Her Royal Highness."

Xia Fan noticed that there was an unfamiliar face next to the other party.

Li, who also discovered this point, turned around quickly and put his tail behind his back.

"Let me introduce, this is the head of the Ministry of Industry and Engineering Bureau, Mo Yun." Ning Wanjun said, "She has known me a long time ago, so she is not considered an outsider. This time, she happened to pass by Jinxia, ​​so she will stay here Last few days."

"And he is the newcomer to the command department I mentioned, and he is also the author of the book you admired so much."

"Lord Xia, I have admired your name for a long time." Mo Yun cupped his hands and said.

"To each other." Xia Fan also cupped his hands in return.

The other party was slightly taken aback.

"By the way, he doesn't know anything about bureaucratic etiquette, and it just so happens that the Privy Council doesn't care about this, so don't worry about his strange behavior." Ning Wanjun smiled slightly.

It can be seen that the princess is in a good mood.

Xia Fan looked at the other party curiously - it can be said that Mo Yun is a woman who absolutely does not conform to the aesthetics of this era. Not only is she tall, her knuckles are slender, and her facial features are also straight.If it is a man, it is naturally very suitable, but if it is a woman, the evaluation will obviously not be so high.

But in Xia Fan's era, Mo Yun is undoubtedly a beautiful girl with a very unique personality, with a taste of the Western Regions, and that plum red lip gloss also proves that she does not want to think of herself as a man.

"The Ministry of Industry used to have female officials." Xia Fan took the initiative to make connections, "I don't know what research Master Mo usually does?"

"This involves the secrets of Qiguo, please forgive me for not revealing."

Unexpectedly, the other party would chat to death as soon as he opened his mouth.

The princess was also a little surprised, she remembered that Mo Yun was not an unsociable person.

"Master Xia, I would like to ask you, that book about arithmetic...was it really you who wrote it?"
