Seeing that several people were already in the play, the sky couldn't continue chatting, Zhao Bing said goodbye and returned to the cabin on the grounds of being tired. "It's not time for dinner, so he walked around and entered his workroom. On one side of the wall was a railing he made, with drawings on it, some were finished, and some were just sketches. Among them were both military and people's livelihood. In short, there were a variety of them, and all kinds of them were included.

These are all advanced equipment that Zhao Bing thought of and knew about the "Ancient and Modern" ones, but some can only stay on the drawings for the time being, because with the current productivity and technology, it cannot be completed. However, some can be made with hard work, but it is also extremely troublesome. Some seem to be just one layer of window paper to understand. There are a few that can be put into trial production at present, most of which are used for military purposes. After he returned to Qiongzhou, he will arrange to transfer to production.

However, Zhao Bing knew that he would write down the method of drying salt now. He calculated that Xiufu would come to ask him for it tomorrow. The current method of making salt from seawater is still "boiling salt", which means filling the seawater into a clay pot, then heating it on the stove so that the water in it can be steamed out, leaving behind salt. The salt cooked in this method has a bad taste, low yield, relatively high cost, and difficult to carry out large-scale production.

As the name suggests, salt drying is to vaporize seawater through sunlight, leaving behind crystalline salt. However, in modern times, salt making has been industrialized, and this almost primitive process has long been eliminated, and only a very small place has been preserved as a cultural heritage. The reason why Zhao Bing can understand this salt making process is thanks to the protection of the Hainan government, which made him for the honor of seeing a performance demonstration of salt drying in his previous life, and learned about the process flow and the tips as top secrets.

In fact, the process of salt drying is not complicated. The first step is to dry salt mud. Use a toothed wooden rake to rake the ground vertically and cross the ground to make the mud soft and fully exposed to the sun for three days; the second step is to collect salt mud and use a wooden rake to put the dried mud into the salt pond. The so-called salt pond is a two-meter-wide, three-meter-long and one-meter-deep pool excavated on the salt field. Bamboo slices and thatch are placed under it to serve as a filtration function. This is the key to making braised. The filtered bamboo slices and thatch must also be replaced regularly.

The third step is to filter. After the salt mud enters the pond, the salt worker needs to step on his feet and inject sea water to obtain brine after filtering for one day. At this time, the salt worker will fold the stem of a plant growing by the salt field and put it into the brine pool. Only when the stem floats on the water surface is the real saturated salt water, otherwise the sun will have to be exposed to the sun repeatedly. Unfortunately, Zhao Bing, who was watching the flowers, forgot what kind of plant it is. When he thought about it, he only thought of a vague name. However, this is not the key. He can think of using other things instead, or maybe it will be clear if he sees it one day.

The fourth step is to collect salt. Pour the brine into the salt tank in the morning. After one day of exposure, if the weather is good, you can use iron plates to scrape salt into the basket and put it in the afternoon. The process of sun-drying salt is not complicated, but insisting on raking mud and exposing the sun every day is not easy. Compared with people's cooking seas, it is much easier to cook salt. Hainan Island, located in the southern country, has inexhaustible sunlight. Salt is the most ideal place, and the efficiency and yield are much higher than that of boiling salt.

Zhao Bing wrote down the method of drying salt according to his recollection, but he felt that this "sludge-dipped and brine-dipped" process was still only suitable for workshop-style production, not for large-scale organized production, and although the production efficiency was improved, it still could not meet his factory requirements. He wondered if there was room for improvement. At this time, he remembered the picture exhibition there, which recorded the gradual improvement of the salt drying process after liberation. In addition to introducing modern equipment to reduce the physical labor of workers, the salt fields were also transformed on a large scale to adapt to large-scale production.

"I can remember, I can remember, I can remember..." Zhao Bing closed his eyes and closed his hands and recited silently, forcing himself to calm down and turn to the 'memory mode'.

"It should be like this..." Recalling his life in his previous life can be said to be an increasingly painful thing for Zhao Bing. He tried his best to reject the flash of his parents and friends and the happy and leisurely days he used to be. Thinking about even the days that made him feel unbearable compared to the crisis he is facing now, this made him even more reluctant to recall his life in his previous life, so as not to survive. It took him a while before he calmed down, and the situation he had experienced and seen during the holiday flashed in his mind, and finally locked on a railing showing a modern salt field.

"..." Wang De had already gained experience. His Majesty must not disturb him when he was "into the gods". No outsiders must approach him, but he must not stay away. He must be careful to serve him. He suddenly saw His Majesty muttering to himself and then reached out and grabbed a pen. He hurriedly leaned over, held his breath, quickly spread a piece of white paper on the table, and then lit the candle.

"Moisture-breaking embankment, flood control embankment, drainage ditches, drainage ditches..." Zhao Bing first drew a few seemingly messy squares and strips on the paper, and then marked them with names.

"Pond, steaming pool, brine pool, crystallization pool, salt pool..."

"There is a gate here to divert water, and there should be a drainage gate there, and there should be a ditch between them..."

"There should be a small path through which people pass, which is connected to the main road. There should also be water lifting equipment and filtering devices!" Zhao Bing drew out the drawing, quickly completed a sketch and then relaxed his mouth, and then filled it at various points on the picture. This was his design routine. He first drew the overall composition, then added the backbone, and finally added details to complete the entire sketch.

"Your Majesty, what is this?" Seeing that Your Majesty put down his pen and breathed a sigh of relief, he stretched his waist again. He knew that Your Majesty was 'awakened', so he quickly brought tea, and glanced at the ghostly talisman-like drawings on the table and asked curiously.

"This is something that can bring us a lot of wealth. You can't even exchange it for a treasure pot!" Zhao Bing said with a smile after taking a sip of tea.

"Oh, then we are not rich!" Although Wang De was already immune to His Majesty's strange thing from time to time, it was the first time he had created a "grape pot" that could make money, which surprised him very much.

"Yes, I'm so rich, but unfortunately I have to be dispatched by the sixth prince!" Zhao Bing sighed.

"Oh, I thought I could go to the warehouse. Now I said we took it, but there was nothing inside!" Wang De said disappointedly.

"Didn't you accept more than forty ships of property? Why don't you have anything yet?" Zhao Bing asked with a strange look on his head.

"Your Majesty, that little thing is not as good as when I was in Lin'an. I think the twenty warehouses under the warehouse that year were under the jurisdiction of the warehouse. The things accumulated in it were piled up like mountains, with countless gold, silver and treasures. Even the three officials had to borrow money from us!" Wang De recalled the grand occasion in the palace that year.
