Xiaoying smiled and listened to Yin Haoran's cheerful report, this first step was a success. While fiddling with the flowers on the table, when I have nothing to do, this flower arrangement is quite time-saving. These days, the eldest lady does not go out of the door, the second door does not step, and does not pay attention to the facts, it seems that all this has been calmed down. Yiyi kept talking on the side of the old man's pillow, and Yin Haoran obviously got some resources, and he was a little ready to move, wanting to show his strength. But some things have to be done slowly, like a slow beef stew, and those who do big things have to stand the test of time.

After living in Yin's Mansion for a few days, when he had nothing to do, Xiaoying wanted to go around the back mountain. These days, there has been no time to be alone and quiet, to step into the green, to feel the reality and presence of this person again.

The grass is green, the sun is shining, there is a large primeval forest in the back mountain, maintaining its original form, early in the morning there are birds singing, butterflies flying in the flowers, crickets occasionally chirping, and gurgling streams from top to bottom, irrigating this large area of green.

Yin Haoran has long boasted that there are many varieties of wild animals here, some of which are precious varieties that the old man specially bought from the Western Regions.

Xiaoying walked for a while, a little sweaty, she wore a modified version of the kung fu suit today, the trouser legs of the big lantern, and the cuffs were embroidered with gold thread, which looked very fashionable.

I didn't see the precious species, but I didn't expect it to be such a coincidence, just now a sika deer ignored her, a human, and went straight in the opposite direction. Coincidentally, there is now another goat on its own journey, and they are all heading in the same direction, without hesitation. Xiaoying felt very strange and strange and followed, and not long after, he saw some animals lining up one after another. They all entered a cave together, and when Xiaoying also stepped into the cave, he saw a very strange sight. These wild animals stood in front of the mountain wall, licking and eating the slippery cave wall incessantly, so engrossed that they did not notice anyone entering the cave.

Shadow thought to herself, are they thirsty? It doesn't look like it, isn't it more thirst-quenching to have a large stream at the mouth of the cave, and they have to lick the walls here. No, there must be oddities.

She looked closely at the walls of the cave, to which was covered a layer of white frost, some milky white, and looked closely at the white thing that the lamb was licking with his tongue. It turns out that these are the things that attract so many wild animals here. Xiaoying dipped a little with her finger and put it on the tip of her tongue, and sure enough, it was salty. I read a book that said that wild animals are obsessed with salt, and bison and goats will travel long distances to lick them in salt-rich natural mines.

After thinking about it, there is such a huge treasure as mine salt hidden in this cave, and no one even knows about it, and if it is used, there is no need to worry about money. Wow, she's going to get rich~~~

She returned to her room and tried to remember the method of refining (purifying) coarse salt written in the book.

After using salt pan evaporation to obtain coarse salt or mining mineral salt from the mine, it cannot be put into consumption immediately, but after obtaining coarse salt, it has gone through three steps of water injection dissolution, filtration and cooking, and the salt obtained after filtration and cooking is not much different from the current edible salt, but because the processing technology is not as fine as it is now, the salt may not be very white (with a small amount of impurities).

Xiaoying got a little salt and went back to study, and made the first package of refined salt based on the refining process in his memory.

At that moment, Xiaoying turned around, and the space overlapped in front of Yin Haoran's door, this antique wood carved door made of excellent pear blossom wood, and the carved flowers and plants were also lifelike.

Haoran happened to go out, and when he saw Xiaoying taking the initiative to find him, he was very happy, and hurriedly invited her in, saying, "Brother Bai came by coincidence, I just thought of you, and you came." ”

"Is there a saying that says Cao Cao, Cao Cao will arrive," Xiaoying smiled.

"Oh, that's an interesting saying, who is Cao Cao? Why haven't I heard it? Is it famous?" Haoran began to think.

I accidentally slipped my mouth and quickly shifted the topic elsewhere.

"Yes, yes, it's just a proverb from my hometown. I have a very important business looking for you today. Xiaoying said to him solemnly.

When Yin Haoran saw her say this, he also became serious, "Brother Bai, please sit down and drink tea." ”

"Let me ask you a question first, do you know salt, where does most of the salt come from?"

"Of course, most of the salt we eat now comes from the sea,"

"Can you show it to me?"

Although Haoran didn't know what her intentions were, he still sent someone to get some. The salt is large and coarse granular, yellowish in color, and the shadow tastes salty in the mouth, but there are a few impurities.

"Why is this salt so coarse, not fine at all? Xiaoying asked.

Haoran was taken aback and said, "This little salt in your hand is already the best salt available in this land, and there are green, green, and black, which are even more unpalatable." ”

"Then you taste mine," Shadow took out a small bag of pure white fine salt from his bosom and poured it on the table like white fine sand flowing. "Is this salt? Why have I never seen it," Hao Ran said, pinching a little and putting it in his mouth, his pupils swelled, it was really real salt, and this essence was very pure, without a trace of impurities.

"Where did you get that?"

"I did it,"

A critical hit Haoran and said, "You still make salt?"

"That's, it's a lot, just kidding," Xiaoying looked a little proud, thinking that she was a scumbag today.

"And where do you get this salt?"

"The mountain behind your house. ”

"What?" it was Kankan's second critical blow, "You were the first to know that there was a salt mine in the mountain behind my house? I have lived in vain all these years, and you are a true god," Haoran said, raising his thumb.

"Hehe, awards, awards, the scale of the mine is not small, we can talk about cooperation. The real topic of Xiaoying's trip began.

"How to cooperate?"

"I can provide a way to refine refined salt, and I will open a store for sale in the future. Xiaoying said, holding up her finger and shaking it in front of Haoran.

"This..."Haoran's heart turned a thousand times, and many thoughts flashed through his mind, such as the principal, the shop, the steward, the relationship between the court, and so on.

"You think, although the salt mine belongs to your family, only I know where it is, and secondly, the method of refining refined salt is only known in this world. Five-five open, you don't lose money, you are starting from nothing, you say this account is worth a lot?"

Yin Haoran looked at Xiaoying's elated appearance when she was talking about business, and the whole person danced, she was a different look, and she was a cute little money fan.
