Then there is no more

Back on the boat, Shen Yi seemed to be still thinking about the matter of drying salt in the salt fields.

There are many small rooms on the ship.For Wanjin Trading Company, Bian Jingyu is a noble cousin, so his room is one of the best rooms on the ship.Shen Yi lives next door to Bian Jingyu.However, except for the time of sleeping at night, Shen Yi spends most of her time in Bian Jingyu's room.Bian Jingyu sat against the table, resting her chin with her hands.Seeing that Shen Yi was absent-minded, he looked at Shen Yi openly.

Youthful feelings are always poetry!

As long as Shen Yi thought about it, Bian Jingyu looked at it for a long time, like a hopeless little fan.

Suddenly, Bian Jingyu pulled out of the state of being a fan, and hurriedly withdrew her eyes, turning her head away from Shen Yi as if there was no silver 300 taels here.After his guilty conscience gradually disappeared, he turned his gaze back calmly and continued to look at Shen Yi furtively.

Alas!He didn't realize I was looking at him!

Bian Jingyu couldn't help but staged a good show of "The Naughty Man and the Stupid Goose" in her mind.

Huh?He still hasn't noticed that I'm looking at him!

The theater in the brain continues to be high-energy, and the sequel of "The Nifty Man and the Goose" "Amorous and Blind" has begun to be staged.

Hmph...he hasn't noticed that I'm looking at him yet!

The comedy quickly turned into a tragedy, and the sequel of "Passionate and Blind" "I am the most pitiful for being infatuated and infatuated, you are so lucky if you are blind and blind" was staged unexpectedly.Bian Jingyu took pity on herself in her heart.The ending of the story is that he was lying in the dilapidated temple with bruises all over his body, holding the token of love between him and Shen Yi - a bunch of cat hair plucked from Jiaojiao's body - while Shen Yi was bragging about marrying the newcomer .

Bian Jingyu's eyes were almost red.It's too miserable, he is really too miserable.

Shen Yi regained consciousness from her contemplation, and seeing Bian Jingyu's sad face, she was frightened, and asked, "Brother Jingyu, are you feeling well?"

Bian Jingyu covered her heart.It's not that I'm not feeling well, it's that I feel sorry for myself!

"Chest tightness?" Shen Yi asked tentatively.

Bian Jingyu shook her head and said weakly: "I'm fine...by the way, what were you thinking just now?"

"I'm thinking about making salt. Have you heard about sun salt?" Shen Yi asked with concern, "Are you really feeling well?"

Bian Jingyu shook her head, thought about it seriously, and said: "Sun salt? I haven't heard of it. However, I read an interesting thing in a book. It is said that there is a salt pond in Meining County. Spring It's time to put the pond water into the salt pond, and the salt can be harvested in autumn."

Meining County is located inland.This salt pond is real.It is said that hundreds of thousands of years ago, the local people used this method to make salt.

Shen Yi asked enthusiastically: "Is this really the case? You can get salt without boiling or frying?"

"This matter is written in the local county annals." Bian Jingyu said with a smile.He felt that he must be very manly at this moment!So, as a man, you can't relax for a moment.Only by reading more books at ordinary times can you keep up with Shen Yi's thoughts at critical moments, and you can hold on!

Shen Yi leaned in front of Bian Jingyu and asked, "What's the reason for this? If you can know the reason why Meining produces salt, you just need to spread this method... There are so many salt fields by the sea, and this method is used , In the future, there will be no need for logging to produce salt, how much cost can be saved!"

Bian Jingyu has indeed read a lot of books, and she is more knowledgeable than ordinary scholars.But he was neither good at nor valued the subject of natural science.

This is caused by the limitations of the times.

Hearing what Shen Yi said, Bian Jingyu was stunned for a moment, and said hesitantly: "I'm afraid it has something to do with the local water and soil? If the reason for the salt production in Meining can really be promoted, how can it be our turn to think about this issue, it must have been done a long time ago." It has been popularized." Don't underestimate the wisdom of the working people!

"That's true..." The excitement on Shen Yi's face gradually disappeared, replaced by a sense of bewilderment, "But I always feel that the seaside can also dry salt. The cost of drying salt is much lower than the cost of boiling salt. If If you can really dry the salt, then the price of salt will definitely be lowered.”

The two fell silent together.

Bian Jingyu felt that he did not read enough books, otherwise he would be able to answer Shen Yi's questions and help Shen Yi.Shen Yi felt more and more at a loss. He clearly felt that drying salt was feasible, but why did he only know the term drying salt, but didn't know how to dry it?

If only there were Du Niang and Gu Ge...

Wait, who is Du Niang, and who is Gu Ge? Could it be a fairy in the sky?Shen Yi wondered if she should offer incense sticks to the two immortals.This name is a bit strange, it doesn't sound like a Buddhist bodhisattva.Buddhism prefers sandalwood, while Taoism prefers agarwood.If Du Niang and Gu Ge are Taoist immortals, then they should be given some incense.For Chen Xiang's sake, would the immortal have a dream?Shen Yi's thoughts ran wildly in the direction of feudal superstition.

Bian Jingyu likes to see Shen Yi in high spirits, seeing his blank face, no matter what Shen Yi thinks in her heart, Bian Jingyu feels uncomfortable first anyway.He said: "We have even grown corn. Can sun-drying salt be more difficult than growing corn? Why don't we try it."

"How to try?"

"First take some salt and dissolve it with water, then turn the salt water back into salt, and see what the rules are here." Bian Jingyu said.He remembered the few private salt dealers who had been arrested before. Manager Qiu said that they could get salt by boiling their clothes.It can be seen that boiling salt is not difficult.

Both of them are the kind of people with strong mobility, and it's okay to stay on the boat anyway, Bian Jingyu immediately led Shen Yi to the kitchen.

Human potential is being forced out.In the past ten years, Bian Jingyu has not been able to cultivate much professionalism in scientific research, but at this moment, he embarked on the road of experimental comparison, saying: "Let's cook a few times first." Salt, let’s see how salt comes from. As long as we find the law of salt production, let’s think about whether we can form the conditions for salt production if we only use drying instead of cooking.”

The two eldest and young masters couldn't light a fire, so they asked the cook on the boat to help.Watching them melt the refined salt into the water, the cook didn't show it on the surface, but his heart ached a lot.I really don't know how expensive oil and rice are. Only the master can afford such good salt. If you say it is a waste, it is a waste!

Put the brine in a pot and bring it to a slow boil over a firewood.When the water in the pot gradually boiled dry, salt appeared at the bottom of the pot again.

"It should be the temperature. When the temperature is high, the salt will come out." Bian Jingyu said based on her own observations.

"It's also possible that there is less water." Shen Yi added from the side.When the salt is boiled, the water in the pot gradually boils dry, so the salt appears.

"If there is less water and salt will appear, then sun-dried salt may be feasible." Bian Jingyu seized every opportunity to encourage Shen Yi and said, "Just pour sea water into a big basin and put the basin under the sun. , the water in the basin will gradually disappear, and the salt will be exposed.”

However, in this way, the efficiency of drying salt must be very low.

"Let's try everything and see if increasing the temperature and reducing the water volume really work," Shen Yi said.

The two ancients studied the chemistry knowledge in junior high school textbooks with great interest.

It is easy to raise the temperature, and it is hot at the moment, and there is ice on board.Bian Jingyu put a glass of water in ice cubes, and when the water temperature dropped, he added some salt to the water.Then, they quickly put the glass of salt water into boiling hot water, allowing the hot water to warm the salt water through the glass.The result was no salt at all!At first they were afraid of adding too little salt, so they tried adding more salt a few times, but there was still no salt!

It was difficult to reduce the amount of water. At the beginning, they wanted the water to evaporate naturally, so they put salt water in a basin and put it under the sun. As a result, the natural evaporation rate was too slow, and there was no effect at all in just a few days.The two could only wait patiently, and could do nothing else.

One day, when Bian Jingyu and Shen Yi were squatting on the deck to observe the water basin, some low-level boatmen were squatting not far away to eat.Probably because of the waves on the road and the unstable boat, the cook of the big pot rice accidentally sprinkled too much salt, so the big pot rice is a bit salty today.Low-level boatmen are the kind of people who are not picky, and they just want to eat enough.They poured some plain water directly into the soup and it tasted just right.A boatman complained that the soup was a bit bland last time, so he had to add salt to it himself.Bian Jingyu noticed this scene, and a flash of lightning suddenly flashed in her mind.

"Brother Yi, if we look at the salt and water in salt water separately, less water means more salt." Bian Jingyu said excitedly, "So we can add salt to the basin and add more. The presence of salt means that our conjecture is correct, and salt can indeed be produced when there is less water."

This is a shift in thinking.

Shen Yi rubbed her chin, felt that Bian Jingyu's method was feasible, and couldn't help but say, "That's so clever!"

Bian Jingyu smiled modestly, but in her heart she also felt that she was very witty.So, as a man, you must have some special skills.Either the body is particularly strong, or the brain is particularly clever, only in this way can one keep up with Shen Yi's thoughts at critical moments, and be able to hold on!

Bian Jingyu is like a male peacock with its screen opened.

Through experiments, it is proved that adding salt to brine (reducing the amount of water in another sense) is indeed useful. When salt is added to a certain extent, salt particles appear at the bottom of the container.In other words, drying salt is also feasible, because the amount of water in the brine will decrease when it is exposed to the sun.

However, when they were doing experiments, they could reduce the proportion of water in brine by adding salt to obtain salt. In practice, sun-dried salt can only be honestly sun-dried, and the efficiency of this is very low.Shen Yi was not satisfied with this, and decided to continue the research with Bian Jingyu.

Let’s talk about the experiment of increasing the temperature. One day, Shen Yi had a whim and suddenly reversed the order of the experiments. First, salt was added to the hot water, and then the hot salt water was put into the ice cubes.After the temperature of the water in the cup dropped, salt appeared at the bottom of the cup!What does this mean?It shows that their thinking at the beginning was wrong. It is not that salt can be obtained from brine by raising the temperature, but that salt can be obtained by lowering the temperature!

"How did you think that the key to getting out the salt is to lower the temperature?" Bian Jingyu felt that Shen Yi was very powerful.

"...I don't know how I came up with this idea, I feel like I'm having a brain twitch." Shen Yi said honestly.

The two ancients didn't understand the principle, but anyway, they did know the law of salt production from brine, one is to lower the temperature, and the other is to increase the concentration of brine.All the way southward, they almost all soaked in the kitchen of the ship, doing things that are meaningless in the eyes of others all day long.

The drama played in Bian Jingyu's mind became "When the golden wind and jade dew meet, it is dry wood and fierce fire".

Really dry firewood.

Because, the two almost burned the kitchen on the ship when they were doing the experiment.

Qiu Guanshi had a headache.The young master of the Bian family is seasick, Qiu Guanshi is afraid that the owner will blame him for not taking good care of the young master, and he has a headache; the young master of the Bian family is no longer seasick, and he takes Master Shen to hide in the kitchen every day to do some strange things, and he is afraid that the young master will take care of the young master. A good ship is tossed and broken, and I continue to have a headache.
