If this Lian Zhongtao is worth cultivating and reusing, it is necessary to take advantage of this little time to take a closer look at his abilities.
"Sir, please go this way."
Lian Zhongtao led the way and took Wang Junlin and his party to the nearest salt field where salt was cooked.
The first thing Wang Junlin saw were the potholes, which were filled with sea water left by the last high tide, but they were not used for drying salt, but for making mud...
Wang Junlin wanted to see Lian Zhongtao's organizational and coordination skills, so he did not come forward and let Lian Zhongtao organize it himself.
Because there was no master craftsman, Wang Junlin simply asked Dong Kang to order all salt workers and salt slaves to rest today. Lian Zhongtao ran into the shack area where the salt workers and salt slaves lived. He didn't know what he said, and ran out two or three times.
Salt workers and salt slaves.
They stood in the salt fields with bare feet in the middle of winter, carrying wooden rakes with teeth, and began to rake the ground in a criss-cross pattern, mixing the seawater with the sand, turning it into hardened blocks under the sun.
The objects are then sent to the rear piece by piece. These are the most common tasks that salt workers and salt slaves do in daily life. At this time, there are even the prefects watching from the side. They are all like chicken blood, so they start to work.
The speed was very fast and it was done in a short time.
Lian Zhongtao came to Wang Junlin and said, "Sir, this is the first step in making salt. Every salt worker and salt slave knows it."
Wang Junlin nodded slightly, not much surprised, but Zhang Tiangang beside him looked at the hardened black mud and thought, what does this have to do with the white salt?
Lian Zhongtao then took Wang Junlin and his party to a ditch that was several miles long. The ditch was also connected to a water storage pond. Lian Zhongtao pointed to the ditch and said: "Sir, it is said that this ditch has been built for 400 years."
For many years, it has been used to pour seawater into the reservoir through ditches during tides, so that water can be fetched later for cooking, which saves the labor of carrying water."
While talking, Wang Junlin followed Lian Zhongtao to a huge pond, which was actually a salt water pond.
Lian Zhongtao ran over, commanded the more than ten salt slaves he had just sent over in advance, put four blindfolded black donkeys on ropes and started
Continuously rotating in circles drives the water wheel, continuously extracting seawater from the salt water pool, and then transfers it to the filter pool behind.
After doing these things, Lian Zhongtao ran over again and said: "Sir, this is the second step of boiling salt. This waterwheel is the key. Previously, the master craftsmen prevented any salt workers and salt slaves from approaching the waterwheel, but the villain
I think that as long as we find a skilled craftsman and carefully take apart the waterwheel and look at it, it will not be difficult to imitate it."
"Okay, here's the next step!" Wang Junlin nodded with a smile, glanced at the waterwheel, and thought that the wisdom of the ancients should not be underestimated. The Sui Dynasty already had a waterwheel.
Lian Zhongtao said quickly: "Sir, the next fifth step is the core skill that the great craftsmen in the past have seen most closely. But I already know how to do it, and now I will show it to you. Sir, please follow me.
come over."
The filters are actually the patches of salt fields seen from a distance, and they are distributed in steps from top to bottom, somewhat similar to terraces. This is to carry out flow filtration layer by layer from top to bottom, and the layers are related to each other.
The water inlet and outlet between the floors contain the biggest secret of the master craftsmen of the salt field. There are always salt workers guarding the place. Under normal circumstances, the salt workers and salt slaves are not allowed to come over.
When Wang Junlin came over, several saltmen hurriedly saluted, but they blocked the frontman Lian Shutao from passing by. Wang Junlin frowned, Zhang Tiangang went up with several guards, and threw aside the saltmen blocking the way.
.
"Sir, what is between the water inlet and outlet between the upper filter and the lower filter is actually a fixed bamboo basket filled with several layers of bamboo mats, and then regularly covered with bamboo slices and thatch, and finally the first step
A hard clay tablet containing a large amount of salt was placed in the middle."
As Lian Zhongtao spoke, he had already directed the salt slaves following him to place the hard clay tablets obtained in the first step in place, and then continued to explain: "Sir, in this way, the salt slaves brought from the reservoir will
After the sea water enters the filter, it flows from high to low. Before entering the next layer, it is filtered through the water level difference first, and then it goes back and forth until it has been filtered for five or six times. The entire time can be as short as one day or as long as
In two days, at the end of the filter at the bottom, you will be able to obtain brine with a higher concentration! If you rely solely on sun salt, this process will take up to twenty days at the fastest even in the hottest time of summer!"
When Wang Junlin saw Zhang Tiangang and the guards looking confused, he knew that they did not understand why. Wang Junlin smiled and said: "Common things in the world can be roughly divided into two types. One is soluble in
Water is another type of person that is insoluble in water, and salt is soluble in water. However, the sediment in the hard clay tablets together with the salt cannot be dissolved in water, so the sediment will accumulate when it enters the water, and the salt will
When it enters water, it dissolves, but the water already tastes salty, so the salt is in the water!"
After hearing this, all the guards were thoughtful, but most of them still looked confused. However, Lian Zhongtao was like a enlightenment, with a look of sudden enlightenment. Although he used his good mind to secretly master the method, he actually knew it.
However, I don’t know why. When I heard the concept of soluble and insoluble mentioned by the prefect, I immediately understood it completely. At the same time, I was shocked by the prefect. I thought that the prefect was indeed not a mortal. He had clearly understood the method of boiling salt before.
He has never been exposed to it, but after watching the process just now, he already understands the truth. However, he has not understood it in the three years since he came to the salt field. He believes that the masters who have been beheaded by the order of the prefect and have been playing with it all their lives are also the same.
He is the same, he only knows the method but not the principle.
Wang Junlin felt the admiration of Lian Zhongtao and the salt workers, and the guards looked at him, and thought that since ancient times, people did not understand the changing process of things and only saw the results. Because they did not understand why, they called them "gods".
', But if you find out this change process and let people know what it is, and take off the mysterious gauze, it is actually science. And over time, after most people know it, it becomes common sense.
After making the brine, Lian Zhongtao secretly took out a piece of dark yellow wood about the size of a palm and about the thickness of a thumb, and then carefully placed the piece of wood in the brine and explained: "Sir, this is
The piece of wood is called Huang Cimu. It was secretly found by the villain from the corpse of a great craftsman yesterday. If it floats on the brine, it means that the brine has reached a sufficient concentration and can be used to boil salt. If Huang Cimu sinks to the bottom of the water or
If it is suspended in the middle of the water, it means that the brine concentration is not enough, and it needs to be filtered before boiling the salt."
Wang Junlin nodded and said: "Yes, I won't look at the boiler boiling salt in the back. You can go clean it up now. Stay with me and live in the post house these days!"
