After nearly a week of exposure, the experimental field has shown preliminary results.

Xia Fan walked barefoot into the lowest crystal pool, and the warm sea water suddenly covered his instep. Compared to the evaporation pond above, the water here is turbid, covered with foam, and reflected with harsh waves below.

This reflection does not come from seawater, but from a thin layer of white crystals at the bottom of the pool.

Gonggong Li couldn't help but bend down, stretched out his hand and poked the mud, and then put it in his mouth, "Salty, salty! This is really salt!"

Although it is not known why this salt grain can be soaked in water, the bitter salty taste is indeed a unique characteristic of sea salt. To be honest, when Her Royal Highness the Princess came up with a sum of money to implement Xia Fan's idea, he was still worried. It's not a matter of money, after all, most of the labor force is borne by His Royal Highness's troops, and the actual cost is not much, and he is worried that once he fails, it will damage the prestige of Her Royal Highness.

Everyone trusts the princess, not the monk found by the princess - if Ning Wanjun fails because she trusts this person too much, then others will inevitably have the suspicion that the princess does not know anyone, and the money can be earned again after it is spent, but it is difficult to make up for the intangible thing such as prestige.

Now that the salt pan has really dried the salt, a boulder in Gonggong Li's heart has finally been put down.

He didn't know what the skills were, and he didn't want to understand it, as long as there was salt in the salt pool, even if it was sprinkled by Xia Fan himself, it would be better than failure.

As soon as the person was satisfied, even Xia Fan's appearance was a lot more pleasing to the eye.

This lad ...... It's pretty good.

"Xia Fan, why doesn't this salt melt?" Li lifted his tail and walked in front of Xia Fan with two steps.

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

In the pool reflecting the blue sky and white clouds, a barefoot girl playing in the water has her back facing each other and overlooking the sea, which is a perfect picture in itself.

What is 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 gaze away and pretended to be serious, "because water can't dissolve salt indefinitely." When its salt content reaches the upper limit, adding salt to it will not melt. This is also the principle of drying and boiling salt – the less water, the less salt it can hold. ”

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

"Indeed," Xia Fan replied carefully, "This pool is just to verify the process, the size itself is too small, and it is the first pool of salt, so it is normal to have less." ”

In addition to this, he found quite a few problems. For example, the height of the evaporation pond and the crystallization pond can be lowered a lot, and it is best to complete a cycle in three days;

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

Li curiously stepped on the pool twice, "Then how will this salt be collected in the future?"

"It's very simple, it's the same as drying millet. Xia Fan smiled, "When it has accumulated a lot, just use a wooden shovel to shovel all the way over." ”

The white "salt mountains" piled up in the pond have always been the most spectacular sight in the salt works.

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

The people around bowed their heads and saluted, "I've seen Her Royal Highness the Princess." ”

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

Li, who also noticed this, quickly turned around and tucked his tail behind his back.

"Let me introduce, this is the director of the Machinery Manufacturing Bureau of the Ministry of Industry, Mo Yun. Ning Wanjun said, "She has known me for a long time, and she is not an outsider. This time I happened to pass through Jinxia, so I will stay here for a few days. ”

"And he, as I am talking about, is also the author of the book that you admire the most. ”

"Lord Xia, I have admired the name for a long time. Mo Yun arched his hand.

"Each other, each other. Xia Fan also returned the salute.

The other party was slightly stunned.

"By the way, he doesn't know anything about bureaucratic etiquette, and it just so happens that the Privy Council doesn't care about that, so he doesn't have to care 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 definitely does not conform to the aesthetics of this era, she is not only tall, her knuckles are slender, and her facial features are also straight. If it's a man, it's naturally very suitable, but if it's a woman, the evaluation will obviously not be much higher.

But in Xia Fan's era, Mo Yun is undoubtedly a beautiful girl with very personal characteristics, with a taste of Western style, and that touch of plum red lip gloss also proves that she does not want to regard herself as a man.

"Originally, there would be female officials in the Ministry of Works. Xia Fan took the initiative to pull the relationship and said, "I don't know what kind of research Master Mo usually does?"

"This involves the secret of Qiguo, please forgive me for inconvenience. ”

I didn't expect the other party to die as soon as he opened his mouth.

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

"Lord Xia, I would like to ask for advice, that book on arithmetic...... Did you really write it?"

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

"It's not. ”

Xia Fan replied quickly.

Mo Yun and the princess were stunned, "Isn't it?"

"yes, I can't make up so many things if I want to make them up, just remembering them is enough of a headache. ”

"And who wrote this book?"

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

If he really wants to break down, it will inevitably involve his origins, so he simply blames it all on the occult.

But what Xia Fan didn't expect was that the princess suddenly showed a look of surprise, "I see...... That makes sense. ”

Wait, do you really believe this?

Mo Yun felt incredible, if the other party insisted on saying that she wrote it, then she could also 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 circulated, it must be a famous work in history, and officials in addition to power and money, don't they just leave a good reputation?

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

This made all her temptations stuck in her throat.

Ning Wanjun saw that the atmosphere was a little stiff, so she took the initiative to change the topic, "By the way, how are the test results of Yantian?"

"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 see?"

"Of course," Ning Wanjun said with great interest, "this is the future of Jinxia City." ”
