Heaven's Formula

Although he knew that the other party was young, Mo Yun was still surprised when he saw it with his own eyes - this person named Xia Fan was too young, he looked almost like a princess.Without the honing of time and experience, how did you write such a rigorous and logical arithmetic course?If you want to judge whether he is deceiving the world, the breakthrough is undoubtedly in this book.

"No."

Xia Fan quickly replied.

Mo Yun and the princess were stunned, "No?"

"Yes, I can't make up so many things if I want to make it up. Memories alone are enough to cause headaches."

"Then who wrote this book?"

"If my master hadn't come to Jinxia, ​​I would definitely say that master taught me. Unfortunately..." Xia Fan spread his hands helplessly, "I don't know, anyway, it was imprinted in my head from the very beginning."

If you really want to break it down, it will inevitably involve his origin, so he simply pushed it all to the occult.

But what Xia Fan didn't expect was that the princess suddenly showed a look of surprise, "So that's the case...it makes sense."

Wait, are you serious?

Mo Yun found it unbelievable. If the other party insisted that she wrote it, then she could find loopholes to make the other party contradict herself, so that His Highness could discover the truth.But he just put the matter aside, as if he didn't care about the honor of "author" at all - you must know that as long as this book is spread, it must be a famous work in history. To leave a good name?

What is even more incomprehensible is that the princess actually believed it!

This made all her temptations stuck in her throat.

Seeing that the atmosphere was a little stiff, Ning Wanjun took the initiative to change the subject, "By the way, what's the result of the Yantian experiment?"

"The situation is not bad. The first batch of salt has been precipitated, but the amount is a little small. Do you want to go and have a look?"

"Of course," Ning Wanjun said enthusiastically, "This is the future of Jinxia City."

Chapter 124

That's right...Yantian, Mo Yun suddenly remembered that the princess came to show him this place.

She doesn't know much about the salt industry. She only knows that salt production is the lifeblood of the country and has great benefits.But the profit of salt lies in the tax, so it should have nothing to do with the princess. Why is Ning Wanjun so concerned about this kind of thing?

When she came to the crystal pool, the princess also took off her shoes and socks, and stepped into the pool excitedly.

"You're right, it turns out that salt can really be exposed to the sun." She held up a handful of salt crystals mixed with mud and sand, and put them in the sun to examine them carefully, "The Wang family probably never imagined that we don't even have a single firewood." Burn it, and you get the purest salt."

"Pure?" Xia Fan raised his eyebrows and said, "Where is this? What you have in your hands is just the lowest grade coarse salt."

"The lowest grade?" Ning Wanjun looked at Li Duojin in surprise, "Eunuch Li, how is the salt in the palace?"

"Returning to Your Highness, it is almost the same as this, but it is crushed and then sifted to make it more delicate."

"I'll just say it." The princess poured the salt back into the water, "Sea salt is bitter, while mine salt is astringent, so well salt has the weakest taste—of course, those that can be paid to the palace are generally of the highest quality." Good batch."

This time it was Xia Fan's turn to be surprised. Don't they have the concept of refined salt at all?The person in front of him is not an ordinary wealthy business family, but Princess Qiguo!

But if you think about it carefully, the matter of purifying table salt is indeed a matter of figuring out the nature of table salt.

"Could it be that you can make it more pure?" Seeing that his expression was wrong, Ning Wanjun couldn't help asking curiously.

"Although it can't be the purest, it can at least remove most of the peculiar smell." Xia Fan nodded, "That's the so-called refined salt - as fine as dust, as white as snow. It's just that this part of the process will greatly reduce the output, so the early stage I didn't think about it. If you want to taste, I can make an extra."

"I want to eat!" Ning Wanjun replied immediately, her eyes were full of light.

This is a rare item that is not available in the palace, and she is determined not to miss it.

Fine as dust, white as snow, just sounds amazing!

In fact, if the princess didn't mention this matter, Xia Fan would refine part of the refined salt himself to satisfy his and Li's appetites.After all, coarse salt is really unpalatable. If you put too little, it will be tasteless, if you put too much, it will be bitter, and other impurities will seriously affect the taste.

In addition, he didn't plan to use chemical purification method-coarse salt is at least edible, and it won't kill you if you eat it. If there are some unexplainable reactants during the purification, it would be tantamount to poisoning yourself.Therefore, recrystallization is undoubtedly the most suitable choice. Taking advantage of the fact that the solubility of salt is relatively stable under temperature changes, the impurities that precipitate faster can be filtered out first, and the remaining water is evaporated at last, leaving relatively pure refined salt.

Of course, the precision of this physical purification method is limited, and it is far from pure salt in the true sense, but at least it will not taste bitter.

Mo Yun stood on the shore, thoughtful.

Although she doesn't know how to make salt, she can deduce the general situation from the conversation between the two of them—the thing called "salt field" in front of her is obviously an unprecedented method of making salt, and it is better than the current method much.

The imperial court will definitely have great interest in this technology.

Therefore, when Ning Wanjun looked at her, she nodded slightly, "If Yanchi can be promoted, the treasury of Qi Kingdom must be filled to the brim—the Holy Majesty will definitely praise His Highness for this."

However, what he didn't expect was that as soon as these words came out, everyone stopped what they were doing and looked at her in unison.

Even Eunuch Li frowned.

Looking at this weird scene, Mo Yun couldn't help taking a step back.

What's going on, did I say something wrong?

"Your Highness... are you sure she is one of your own?" Xia Fan asked in a low voice.

"This is a misunderstanding." Ning Wanjun coughed twice, and then said seriously to Mo Yun, "I don't intend to report this technology to the imperial court, let alone exchange it for a reward from the Holy Majesty. Everything you see today is gold. Xiacheng’s secret, so no matter who it is, don’t reveal this matter, can you?”

"Of course no problem." Mo Yun responded quickly, but his heart was full of doubts.

And one thing she knew very well, that is, after she said those words, the people around her were obviously wary of her.

Mo Yun suddenly felt a little bitter.

The two have been separated for too long, and even if the past connection is still there, the surrounding interpersonal relationships have changed.

"Let's go back to the villa first," said the princess.

"Can I...can I have a few more words with Master Xia?"

The other party is in charge of the command department. If there is no princess to take the lead, she won't be able to meet if she wants to.Mo Yun has not forgotten the reason why she came here, and she cannot be discouraged by this little accident before she gets a definite result.

"Yes." Ning Wanjun put on her shoes and socks again.

"You said he knew a lot, didn't you?"

"According to his own words, he knows a little bit about everything."

This person... is quite cautious.

Since that arithmetic book can no longer be used as a breakthrough, she can only start from the field she is familiar with.

After Xia Fan came over, Mo Yun regained his mind and said, "Master Xia, you asked me about the research of the Ministry of Industry, but we actually encountered a very difficult problem. Your Highness said that you might be able to come up with some ideas that ordinary people can't predict. , so I would like to ask your opinion."

"Wait," Xia Fan stretched out his hand to stop it, "Didn't you just say that it was a national secret? I don't want to be wanted by the Ministry of Criminal Justice for a reward just because I heard this."

"That's... for outsiders." Mo Yun pretended to be calm, "Besides, I also saw the secret of Jinxia City just now, so it's an exchange."

Can this be exchanged?Xia Fan silently slandered, I think this is just an excuse.

However, he is also really interested in the research of the Ministry of Industry, which after all represents the highest level of manufacturing in Qiguo. "Okay, just ask."

Mo Yun squatted down and opened the wooden box that was always with him.

In addition to some personal items, it is mainly used to store the model of the mechanism beast.

This is also the most critical technology she presided over to conquer.

Mo Yun placed the built-in bronze four-legged beast on the sand, and at the same time injected the Qi in his body into it——

The four-legged beast stood up slowly, and took a step forward from left to right!

"Oh?" Ning Wanjun let out an exclamation, "I remember that this thing was just an idea of ​​yours before, but it has come true now?"

"If you just let it move, the Machine Building Bureau has already made a real object that is the size of a cow and a horse." Mo Yun said proudly, "But in terms of practical application, there is still a key problem that is difficult to solve."

Speaking of which, she looked at Xia Fan, "I wonder if Master Xia can solve this problem for us?"

Chapter 125 The key is form!

"What's the key question?" Xia Fan also felt extremely novel. What did he see?An ancient remote control toy!Being able to move means that it has a source of power; being able to remotely control means that this power can be manipulated by others!

As early as when he saw the Lingtai, he was already thinking about whether energy and strength could be transformed into each other, but the Ministry of Finance used the excuse that the Lingtai was expensive and rare, and was still unwilling to show it to him for a closer look, so Xia Fan had no choice but to give up.Unexpectedly, the Ministry of Industry has already started similar research, and it has produced impressive results.

"It's bumpy and easy to fall." Mo Yun explained in detail, "Its design purpose is to assist Qiguo's army in transportation and fighting. The bronze skeleton allows it to carry a huge weight without collapsing. It does not use traditional wheels and The quadruped structure is adopted so that it can climb over mountains and mountains, and no matter where the frontier troops go, it can always keep up."

"Bold idea." Xia Fan was amazed.

"But it can't be stable for the time being." With the injection of ink cloud and air, the quadruped's pace was much faster, but it also visibly shook.This shaking comes from the inability of the limbs to maintain the same landing frequency. One side is fast and the other is slow, which will cause it to tilt to the slow side, and its movement looks quite stuck. "If this thing is only as big as a model, it won't hurt if it's unstable. However, if it's enlarged to the level of a cow or a horse, this shortcoming cannot be ignored."

Once the weight goes up, the shaking effect will increase exponentially, not to mention leaving the official road and climbing the rugged hillside.

Even because of this problem, there has been an accident in which a tester was crushed to death by an overturned quadruped in the Mechanics Bureau.

Of course, Mo Yun didn't think that the other party could solve this problem.

Mechanism manufacturing is a highly specialized manual work.

She brought it up here, but she wanted to lower the princess's evaluation of him step by step.

He couldn't solve the most difficult problem, so he changed to an easier problem. Anyway, the Ministry of Industry has accumulated dozens if not hundreds of problems.In this way, His Highness's opinion of him "can do anything" will change.

Mo Yun has already seen it.

The other party is definitely not a charlatan in the traditional sense. He doesn't seem to value reputation so much, and he still has one or two unique skills in certain fields.Although it is not clear where the princess's excessive trust in him came from, as long as Ning Wanjun's view is corrected, the situation is not as bad as Qiuyue described.

——There should be no omniscient person in this world.

Mo Yun thought so.

However, the other party did not show the embarrassment or pretended deep expression she expected.

"I guess even if it is on flat ground, it often has joint jamming failures?" Xia Fan picked up the bronze quadruped, looked at it fondly, and once again marveled at the wisdom of the mechanism.In this small model, a transmission structure similar to gears has appeared.

She raised her eyebrows unexpectedly, "Why do you say that?"

"The gears are very worn, which means it doesn't mesh perfectly. It wears out so fast, so it has to be replaced from time to time. To facilitate repairs, these parts are not completely wrapped, and the wind and sun will only make it broken. faster."

This person... actually knows tricks?

Mo Yun blinked, feeling a little dazed for a moment.

It has to be said that the problems pointed out by the other party are all old problems that have plagued the Mechanism Bureau on weekdays. Most people are already dizzy just seeing the exquisite internal structure of this thing. How can he see the flaws at a glance?

"This kind of problem... can't be avoided at all." She replied after a while.

"If the gears are designed in advance using the involute principle instead of engraving by hand, the two can be meshed one by one, and you don't have to stare at its joints all day long."

"Involute? What's that?"

This made Xia Fan question—essentially speaking, this is a concept of curve differentiation, and it can be said as common sense, but now it is a bit embarrassing for him to list the formulas in full.Advanced mathematics can be forgotten after a few years, not to mention that he has been here for more than ten years.

"Ahem, it's hard to explain this one or two sentences clearly. If you understand that the gears designed according to this method, if there is no accident, even if they run for several years, they will not cause jamming or wear due to their own problems."

Is there really such a way?Mo Yun hesitated, why had she never heard of it?Whether it is Mohism or public loser, the fit of the toothed roller is extremely dependent on the skill of the caster, so that skilled craftsmen are family treasures, and even their experience and knowledge have become a unique part of the caster. Biography's exclusive secrets.

The other party thinks that carving by experience is a bad thing?

Before she could think about it, Xia Fan changed the topic at this time, "But even if this defect is solved, at most it can only improve the problem you mentioned, and it is almost impossible to completely eradicate it—— It's like you can't really control a kite."

"Why?" Ning Wanjun asked curiously.

"The operator can only observe the pebbles and puddles under his feet, the depressions and uplifts of the ground with his eyes. Not to mention the existence of errors, even if he makes mistakes, it is difficult for him to get feedback in the first time." Xia Fandun said Dun, "Similarly, if you can't fly a kite as high as you can, you won't be able to feel the specific direction of the wind."

"Is that so?" The princess looked at Mo Yun.

The latter was silent for a long time before slowly replying, "He...is right."

More than right, it hit the nail on the head.

This is also the crux of what has always been in her heart.

The Bureau of Mechanical Engineering has been working hard for several months, but they still haven't found any clues.The created mechanical beast can indeed come and go freely on the flat ground, but once it is changed to an unfamiliar environment, the operator's proficiency decreases, and it obviously loses its way.

The biggest problem with the mechanism beast lies in the human itself.

If this is not resolved, it will always remain a model.

"Of course...as long as you change your mind, it's not that difficult to deal with."

"Do you have a solution?" Mo Yun asked almost subconsciously.

"Yes. No." Xia Fan said frankly, "I said, if you still adopt the form of a quadruped, it is almost impossible to solve it."

According to the solution of another life, it is still an extremely difficult task to maintain the dynamic balance of the machine. Relying on a large number of sensing probes and gyroscopes, plus electronic processors and continuously improved algorithms, can barely achieve "steady stability" when affected by external forces. Inverted", this set of plans has no reference meaning for the current machine building bureau.

Mo Yun was attracted by this answer, "You mean...the current form is a wrong choice? Then what should it look like?"

Xia Fan pointed to himself.

It took a while for her to realize, "Human-shape?"

"Not bad, and it just fits one person into it." Xia Fan nodded seriously.There is no more delicate gyroscope than human beings, even if there is a slight bump on the ground, it can immediately react to it the moment it lands. "Since you can't control the kite standing on the ground, you can simply put yourself in the sky and experience the changes of the wind yourself."

Mo Yun felt like a flash of lightning flashed in his mind!

Can people carry things on their backs?
