Then, he turned to Nangong Ye with a smile on his face and said slowly, "In a few days, we plan to go to the seaside and then return to the northern border.
At present, the construction projects there must be almost completed.
And next, I must repair the road from the north to the canyon as soon as possible!"
Upon hearing this, Nangong Ye nodded to show his understanding, and then said, "Do you need me to accompany you to the beach? It will only take three days to go there and back." His eyes were sincere, revealing his concern.
Jiang Ling shook his head gently and declined, "No need. The cement factory has just started, and there are other important things you need to take care of, such as road construction. How can you find time to go sightseeing?
Don't be lazy.
Once the road is completed, it will be very convenient for us to travel between our two cities."
After saying that, Jiang Ling patted Nangong Ye on the shoulder to show encouragement and trust.
"Well, if that's the case, then if you need any assistance, just let me know."
Nangong Ye thought to himself that he really had a lot of things to do, so he didn't force himself to go with him.
"Okay, no problem."
After returning to Nanyu City, Jiang Ling took Yue Qianli and the child to the palace again.
At this time, the tools, coarse salt and mineral salt collected from the salt mine that they had been asked to prepare were almost all ready.
It has to be said that there is strength in numbers.
At that time, Jiang Ling had mentioned that if a salt mine could be found, salt production would be more convenient and cost-effective.
I didn’t expect that I would find it in less than half a month.
I have to say that God is protecting the Southern Song Dynasty.
Then, in the imperial study, a group of people gathered together. Jiang Ling explained the operating procedures, one person was responsible for writing them down, and the others followed the procedures, doing it step by step.
One is the purification of coarse salt. The salt dried out from seawater is coarse particles with a bitter taste and a very bad taste, which will also affect the taste of cooking.
Generally, only ordinary people buy it.
The royal nobles here used well salt, which tasted much better than sea salt. However, the salt-making process was complicated, inefficient, and had low output.
Ordinary people can’t afford it.
So, since they have ready-made sea salt, it is not impossible to simply purify it and continue to eat it.
Jiang Ling explained step by step:
“First, put the coarse salt into a container, add an appropriate amount of water, and stir to speed up the dissolution.
Then, pour it into the filter and remove the insoluble impurities along the inner wall.
Next, heat and evaporate. Stir constantly to ensure that the container is heated evenly. Stop heating when more solids appear.
Finally, the remaining liquid is evaporated using the residual heat to obtain refined salt.”
A quarter of an hour later, what appeared before everyone were grains of snow-white, fine salt.
The operator excitedly grabbed a small amount of refined salt, put it in his mouth, and instantly widened his eyes and said with a smile.
"Hahaha, really, not bitter or astringent, delicious."
Others also learned to grab a small bit and try it out.
Even Nangong Yumo and the others couldn't help but eat a little.
In an instant, there was a burst of laughter in the imperial study.
After everyone calmed down, Jiang Ling continued to explain the salt production process in the salt mine.
At this time, one of the technical craftsmen couldn't help but speak.
"Princess, to be honest, the salt produced in this salt mine may be poisonous. There was once a person who couldn't afford to buy salt, so he went to the salt mine to dig it out and made it himself. As a result, he was poisoned to death after eating it.
After that incident, no matter how poor a person is, they will not eat salt from the salt mine."
Jiang Ling looked at him, smiled and nodded. He was quite brave and had a conscience.
Then, he glanced at everyone and said, "Don't worry, you can let the animals try the salt we'll make soon."
Nangong Yumo certainly believed Jiang Ling, so he said, "It's okay, Fourth Sister-in-law, just make it. I'll have someone prepare the small animals and try it out. Everyone can rest assured, and we will have relevant evidence in the future."
Jiang Ling nodded to show that he understood.
So, he continued to explain the operating procedures to the technicians.
“First, crush the salt ore, put it in a container, add water, stir, and heat to dissolve it.
The next step is to purify the brine. There are impurities, mud or other minerals in the salt ore. The heavy impurities are precipitated, and then those tiny impurities are filtered out to make the brine relatively pure.
The same is true in the end. After heating, evaporation and cooling, the crystals obtained are fine salt.
In fact, the steps are similar, but the most convenient and cheapest way is to make salt from salt ore."
After Jiang Ling finished his instructions, he sat there and watched them operate. Everyone was doing it seriously.
This concerns the people's livelihood in the Southern Song Dynasty. If successful, not only will their living standards improve, but they can also sell to other countries.
Nangong Yumo just stared at it, feeling a little nervous and excited.
No one thought that making salt could be so simple and easy?
How could they not think of this? They are really wasting their brains.
If Jiang Ling knew what he was thinking, he would just roll his eyes and look down on him.
Is this simple? Easy?
This is the crystallization of human knowledge, but it is not easy at all.
Jiang Ling and Yue Qianli just drank tea quietly, while the others couldn't sit still and watched eagerly.
After about half an hour, everyone saw snow-white fine salt again.
This time, no one dared to give it a try.
So, he gave it to the prepared rabbit.
Jiang Ling did not take the initiative to try it. Many times, they had to go by themselves.
The rabbit ate the fine salt for about a quarter of an hour.
It was full of life and showed no change at all. It just drank a sip of water. The person who fed it the salt was a bit cruel and gave it a big spoonful.
After a quarter of an hour, I was back to normal and ate green leafy vegetables.
In this way, a quarter of an hour passed, until almost two hours later, they had finished their dinner.
The little rabbit ate a lot of green leafy vegetables again.
Only then did I feel completely relieved.
Suddenly, everyone was excited.
Jiang Ling couldn't help but sigh when it came to things that were good for the people's livelihood and the country.
From top to bottom, he was as happy as a child.
Seeing this scene, Jiang Ling finally fulfilled his gratitude to Nangong Yumo.
It's time for them to go to the beach and play.
After saying goodbye to Nangong Yumo and the others, Jiang Lingyue Qianli and his group left Nanyu City with smiles on their faces.
Three days later, they arrived at the seaside.
The sea breeze blows gently, carrying a salty scent, and waves hit the shore one after another, making crisp sounds.
Jiang Ling and Yue Qianli stood side by side on the beach, looking at the endless sea. At this moment, both of them were in an exceptionally calm mood.
They couldn't help but look at each other, grinning and laughing.
