Heavenly Dao Formula

That's right... Yantian, Mo Yun suddenly remembered that the princess was here to show her around.

She doesn't know much about the salt industry, only knows that salt production is the lifeblood of the country and has great benefits. However, the profit of salt lies in the tax, and 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 crystallization pool, the princess also took off her shoes and socks and stepped into the pool excitedly.

"You're right, so salt can really be exposed to the sun." She took up a handful of salt crystals mixed with sand and put it under the sun to examine it carefully. "The Wang family probably never dreamed of it. We didn't even have a single firewood. Burn it to produce the purest salt."

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

"The lowest grade?" Ning Wanjun looked at Li Duojin in surprise, "Grandpa Li, what is the salt in the palace like?"

"His Royal Highness, it's not much different from this, but it's crushed and sieved, which is more delicate."

"Let me just say it." The princess poured the salt in her hand back into the water. "Sea salt is bitter, and the mineral salt is astringent, so the taste of well salt is the weakest. Of course, those who can pay tribute to the palace are generally of the highest quality. The good batch."

This time it was Xia Fan's turn to be surprised, don't they have the concept of refined salt at all? What is in front of you is not the ordinary wealthy merchant family, but the princess Qiguo!

But think about it carefully, the purification of table salt is indeed a matter of waiting until the essence of table salt is understood.

"Could it be that you can make it more pure?" Ning Wanjun couldn't help but curiously asked when he saw that his expression was wrong.

"Although it can't be the purest, but at least it can remove most of the odors." Xia Fan nodded, "That is the so-called refined salt-as small as dust and white as snow. But this part of the process will greatly reduce the output, so the early stage I did not consider it. If you want to taste, I can make a little extra."

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

This was a rare thing not in the palace, she never wanted to miss it.

As thin as dust and white as snow, it just sounds amazing!

In fact, the princess didn't mention this, Xia Fan would also refine some refined salt by himself to satisfy himself and Li's appetite. After all, the coarse salt is really not tasty, it is less tasteless and bitter, and the other impurities will seriously affect the taste.

In addition, he didn't plan to use chemical purification methods-the coarse salt can at least be eaten, and it won't kill you if you eat it. If any unexplainable reactants were raised during the purification, it would be tantamount to poisoning yourself. Therefore, recrystallization is undoubtedly the most suitable choice. Taking advantage of the relatively stable solubility of salt under temperature changes, it can first filter out the impurities that precipitate faster, and finally evaporate the remaining water, leaving behind the purer refined salt.

Of course, the precision of this physical purification method is limited, and it is still a thousand miles away from the true pure salt, but at least it won't be bitter.

Mo Yun stood on the shore, thoughtful.

Although she does not understand salt production, she also infers 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 salt production, and it is better than the current method. Much.

The imperial court will be very interested in this technology.

Therefore, when Ning Wanjun looked at her, she nodded slightly, "If Yanchi can be promoted, Qiguo's treasury will surely be filled with dangdang--the Holy Master will certainly appreciate your Highness for this."

What was unexpected, however, was that as soon as these words came out, everyone stopped working and looked at her.

Even Grandpa Li frowned.

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

What's the matter, did you say something wrong?

"His Royal Highness... Are you sure she is your own?" Xia Fan asked in a low voice.

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

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

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

Mo Yun suddenly felt a little bitter.

The time between the two is too long, even if the past connection is still there, the interpersonal relationship around is already a matter of fact.

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

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

The other party is engaged in the mission, if there is no princess to take the lead, she would not be able to see if she wanted to. Mo Yun hadn't forgotten the reason for coming here. She couldn't be discouraged by this little accident before she could get the exact result.

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

"You said he knows a lot, right?"

"According to his own words, he knows a little bit of 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 mentality and said, "Master Xia, you asked me about the research of the Ministry of Engineering. Actually, we encountered a very difficult problem. Your Royal Highness said that you might be able to come up with some ideas that ordinary people would not expect. , So I want to ask your opinion."

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

"That's...for outsiders." Mo Yun pretended to be calm, "not to mention that I also saw the secret of Jinxia City just now, so it's a good exchange."

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

However, he is really interested in the research of the Ministry of Industry~www.ltnovel.com~ that after all represents the highest manufacturing level of Qiguo. "Okay, just ask."

Mo Yun knelt down and opened the wooden box he had been carrying around.

Except for some personal items, it is mainly used to store the models of organ beasts.

This is also the most critical technique she managed to overcome.

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

I saw the four-legged beast slowly stood up, and moved forward one by one!

"Oh?" Ning Wanjun exclaimed, "I remember this thing was just a vision of yours before, has it been realized now?"

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

Having said that, she looked at Xia Fan, "I wonder if Master Xia can overcome this problem for us?"
