Seeing that several people had already entered the play, and they couldn't talk anymore, Zhao Yu quit and returned to the cabin on the grounds of sleepiness. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 It was not yet dinner time, so he walked around and went into his workshop, and on one side of the wall was a railing he had made, covered with drawings, some of which had been completed, and some of which were just sketches. Among them, there are both for the military and for the people's livelihood, in short, there are all kinds of things.

These are all the 'ancient and modern' advanced equipment that Zhao Yu thought of and knew, but some of them can only stay on the drawings temporarily, because they cannot be completed with the current productivity and technology. But some of them can be made with hard work, but they are also extremely nerve-wracking, and some seem to be only a layer of window paper to penetrate. At present, there are a few things that can be put into trial production, most of which are used for military purposes, and he will arrange for them to be transferred to production after he returns to Qiongzhou.

However, Zhao Yu knew that he still wrote out the method of drying salt now, and he calculated that Lu Xiufu would definitely come to ask him for it tomorrow. At present, the method of making salt from seawater is still 'boiling salt', which is to put seawater into a clay pot and then heat it on a stove so that the water in it can evaporate, leaving salt behind. The salt cooked in this method has a bad taste, and the yield is low, and the cost is relatively high, making it difficult to produce on a large scale.

As the name suggests, salt is the salt that evaporates the seawater through sunlight, leaving behind the salt that crystals. However, in modern salt production, which is already industrialized, this almost primitive process has long been obsolete, and only a few places have been preserved as a cultural heritage. The reason why Zhao Yu was able to understand this salt-making process was thanks to the protection of the Hainan government, so that he was fortunate to see the live demonstration of the salt drying performance in his previous life, from which he learned about the process and the trick of being a top secret.

In fact, the process of drying salt is not complicated, the first step is to dry the salt mud, and use a wooden rake with teeth to crisscross the ground to make the mud soft and fully exposed to the sun for three days; The second step is to collect the salt mud and use a plank rake to put the dried mud into the salt pond. The so-called salt pond is a two-meter-wide, three-meter-long, one-meter-deep pond excavated on the salt pan, with bamboo and thatch underneath to play a filtering role, which is the key to making brine, and the filtered bamboo and thatch should also be replaced regularly.

The third step is filtration, after the salt mud enters the pool, the salt worker needs to step on the ground, and then inject seawater, filter for a day to get the brine, at this time, the salt will break off the stem of a plant that grows on the edge of the salt pan and put it into the brine pool, only the stem floats on the water surface is the real saturated brine, otherwise it will be repeatedly exposed to the sun. It's a pity that Zhao Yu, who is looking at the flowers, has forgotten what kind of plant it is, and he only thinks of vague names when he wants to break his head, but this is not the point, he can think of replacing it with something else, or maybe it will be clear when he sees it one day.

The fourth step is to collect salt, pour the brine into the salt trough in the morning, and after a day of exposure, if the weather is good, you can scrape the salt with an iron plate in the afternoon and put it in the basket. The process of making salt from the sun is not complicated, but it is not easy to insist on raking the mud hard every day and exposing it to the sun. Compared to people's boiling the sea for salt, it is still much easier. Located in the southern part of Hainan Island, which has an inexhaustible supply of sunlight, drying salt is the most ideal place, and the efficiency and yield are much higher than boiling salt.

Zhao Hao wrote down the method of drying salt according to his recollections, but he felt that this process of 'pouring mud to extract brine' was still only suitable for workshop-type production, not suitable for large-scale organized production, and although the production efficiency was improved, it still could not meet the requirements of his own factory. He wondered if there was room for improvement. At this time, he remembered the photo exhibition there, which recorded the gradual improvement of the salt drying process after the liberation, in addition to introducing modern equipment to reduce the manual labor of the workers, and the large-scale transformation of the salt pans to accommodate large-scale production.

"I can remember, I can remember, I can remember......" Zhao Yu closed his eyes and folded his hands and meditated silently, forcing himself to calm down and turn into 'memory mode'.

"It should be like this......" Recalling the life of his previous life can be said to be an increasingly painful thing for Zhao Yu, he has to try his best to abandon the flashing image of his parents and friends and the happy and leisurely days he once had, thinking about the days that made him miserable at that time, compared to the crisis he is facing now, it is simply not a fart, which makes him even more reluctant to recall the life of his previous life, so as not to live more and more. It took him a while to calm down, and his mind flashed back to what he had experienced and seen during that holiday, and finally locked on a railing that showed a modern salt farm.

"...... "Wang De has already experienced, His Majesty must not be disturbed when he is 'in the gods', outsiders are not allowed to approach, but he himself cannot stay away, he must be careful to serve." Suddenly, after seeing His Majesty muttering to himself, he reached out and grabbed a pen, hurriedly tiptoed over, held his breath, quickly spread a blank piece of paper on the desk, and then lit a candle.

"Tidal embankments, flood control embankments, drainage ditches, drainage ditches, ......" Zhao Hao first drew a few seemingly messy squares and strips on the paper with a pen, and then marked them with their names.

"Ponds, evaporation ponds, brine ponds, crystallization ponds, salt ponds, ......"

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

"There should be a small road between them, which is connected to the main road. There should also be equipment for lifting water, a device for filtration! Zhao Yu sketched and quickly completed a sketch before he was relieved, and then filled in the various points on the drawing. This is already his design routine, first drawing the overall composition, then adding the backbone, and finally adding details to complete the whole sketch.

"Your Majesty, what is this?" Seeing that His Majesty put down the pen and breathed a sigh of relief, he stretched his waist again, knowing that His Majesty was 'awake', he hurriedly sent tea, and by the way, he glanced at the ghost-like drawings on the table, and asked curiously.

"This is something that can bring us a lot of money, and we won't change it for a cornucopia!" Zhao Yu took a sip of tea and said with a smile.

"Oh, then wouldn't we be rich!" Although Wang De has long been immune to His Majesty's strange things from time to time, it is the first time that he has made a 'cornucopia' that can make money, which makes him pleasantly surprised.

"Yes, I made a fortune, but unfortunately I have to go to the land phase dispatch!" Zhao Hao sighed.

"Alas, the little one thought it could be returned to the inner storehouse, but now it is said that we will take it, but there is nothing in it!" Wang De listened and said in disappointment.

"Didn't you accept more than forty ships of property, why don't you have anything?" Zhao Yu raised his head and asked strangely.

"Your Majesty, that little thing is not as good as in case of Lin'an, I think that there were twenty warehouses under the jurisdiction of the treasury back then, and the things stored in it were piled up, and the gold and silver treasures were innumerable, and even the three divisions had to borrow from us!" Wang De recalled the grand occasion in the palace back then.

"Oh, then you'll have to tell me what's going on with this vault!" Zhao Yu came and said with interest...... (To be continued.) )
