For Yantian, Zhu Zilong did not just be a passer-by and just a monopoly seller.

The laptop contained the information he had inadvertently collected before, and with just a few small changes, it was possible to make a big difference in the quality and quantity of Haiyantian.

The real salt drying is by no means digging some condensation and evaporation ponds on the beach to produce salt in batches.

Don't look at the late Ming Dynasty now, but most of the salt farms still use the soil method, and boiling the sea for salt is still the most widespread salt making method.

These days, Zhu Zilong brought people with them to dig out a large area of stone salt troughs that looked like inkstones under the embankment, and the placement of these salt troughs was very exquisite, seemingly stacked together irregularly, but in fact the height was staggered.

Then the salt mud with small ingredients is added to the guide and improved, attracting seawater to evaporate the water after a few days in the sun, and this salt mud contains a high salt content.

Seawater is then injected, and the filtered water flows into the brine pool on one side from the small opening reserved next to the salt pond, and there is a pool of high-grade brine.

The brine reaches 5~10 degrees (Baumé degree), and after being put into the brine pool, it is then concentrated to 20~25 degrees, and collected back by the brine ditch. How to judge the concentration of brine?

Quite simply, floating on the surface of the water with plant stems is the real saturated salt water, otherwise it will be repeatedly exposed to the sun.

Finally, a nearby place with volcanic rocks was selected to form a salt trough.

There are tiny holes in such stones, and finally the brine is poured into the salt trough, and after a day of exposure, the salt can be scraped with a board at dusk and put into the bamboo basket.

In this way, the efficiency and quality of the entire salt production will also be improved by NNN.

After multiple modifications, it is even possible to increase the output of high-grade fine salts. To be honest, when he first found that even high-grade coarse and fine salt could increase production, Zhu Zilong was also shocked.

These looked very much like the refined salt made in modern salt factories, which greatly surprised him, can sea salt reach this level without going through the refining process?

Trying to put some with his finger in his mouth, Zhu Zilong felt that these sea essence salts were much lighter than the fine salt he brought from modern times, and they melted in his mouth. However, it can be regarded as a first-class high-quality salt!

(It turns out that if you use the ancient method to improve it, you can also make a salt that looks similar to modern fine salt in terms of color and luster.) Seeing this, does it make some people who think that the ancients can only eat impurity salt and black salt are disappointed, hehe! ）

Zhu Zilong didn't know what the sodium chloride content of these fine sea salts that looked no different from modern salts was.

However, just by virtue of the appearance of this salt, it is not a hot item.

Before monopolizing and taking over the current official position, to be honest, Zhu Zilong knew that salt was very important to the ancients, but he would never understand it so clearly as he did when he entered the industry now.

A small salt looks unremarkable, but in ancient times, and now in the Ming Dynasty. But it was once the key to the life and death of a country and its prosperity, and the value of salt to an agricultural society was no less than the value of oil to an industrial society.

There are many reasons for this, one of which is that salt is the equivalent of an ancient refrigerator.

As a modern person, you may only see salt as a seasoning agent for daily cooking, but in fact, the meaning of salt to ancient people is more like the meaning of refrigerators to modern people.

In ancient times, salt was the most important preservative for vegetables, meat, fish, and milk, because these foods are perishable and spoiled, unlike cereals, which can be stored for a long time.

But if salted into pickles (sauerkraut), ham, salted fish, cheese products, they can be preserved for months or even years. Ancient farmers often needed to exchange grain for salt to make pickled foods.

So, in ancient times, salt was not just a food for eating, but also a food additive for necessities.

In addition to the long-term use of pickled food, but more importantly, with salt, merchants can achieve long-distance food trade, which is equivalent to the ancient version of cold chain logistics. Plenty of necessities for everyone!

In ancient times, people in the interior could not eat sea fish, but they could be transported inland as salted fish. People in agricultural areas do not have access to dairy products from the northern steppes, but salt can be processed into cheese and shipped to the south. People in the hinterland of the Central Plains can also dry the beef into corned beef jerky and transport it to the four directions.

Therefore, in ancient times, salt was even a major basic support point for the commercial economy.

Also, for the state.

As long as the supply and price of salt are controlled, a food excise tax can be levied on all consumers. Ancient Chinese dynasties relied heavily on salt taxes, which were one of the largest sources of government revenue.

The salt tax does not need to spend money to raise a large contingent of civil servants who collect taxes, nor does it cause conflicts between the government and the people because of the tax, which is really the best means of taxation. "Guanzi National Savings": "If the people give, they will be happy, and if they take it, they will be angry, and the people's feelings will be the same." The first king knew what it was, so he saw the form of giving, but did not see the reason for taking. ”

If it weren't for the current late Ming Dynasty, the country would be chaotic and natural disasters would not stop. There was chaos inside and outside, and the scholars and landlords were not of the same mind as the emperor. How did the people below have a chance to smuggle salt in a big way?

Zhu Zilong naturally came to the right time and the right way because of this, and the time and place are favorable, so that he has the convenience now.

In the face of this kind of opportunity, he naturally has to firmly grasp it.

(Salt is one of the lifeblood of revolution and development, and even Chairman Mao once said: "It is better to lose Yan'an than to lose Yanwan")

Zhu Zilong, who has mastered the semi-monopoly of the salt industry within a radius of hundreds of miles, has worked hard for more than a month.

Let the place become peaceful, such a person will naturally become a character with ability, ideas, and decisions in the eyes of everyone. In addition, his so-called American products from thousands of miles away took the right route in the backyards of the upper class and landlords in several nearby cities.

For a while, compared with his predecessor, Zhu Zilong obviously made people feel that he was much more popular, more generous (more gifts), and more appropriate.

Looking at the gradual changes around him, Zhu Zilong, as a traverser, had a sense of pride in his heart gradually rising.

It's only been a few months since he came here, and he has done a lot of positive things, and many people are following him, and now he can not only increase his income to supplement his family. Keeping them safe and secure is one of the achievements.

Calculate the time, there are still a few days, Zhu Zilong will be able to open the copycat moonlight treasure box again and return to the modern 21st century in two days.

These days, every week he would control the emperor's clone who was far away in the capital, and wake up once or twice. After checking the key points of the recent recitals, I found that there was nothing too wrong with the state affairs, so I temporarily put my mind to it.

(The emperor's physical condition was so poor that he could theoretically wake up for two or three hours a day, but the result was that he often had to rest for two or three days after one control.) ）

Before returning to the modern side, Zhu Zilong in Shandong decided to visit the stores that cooperated with the Zhang family in several nearby big cities and sold daily chemical products.

In addition to reconciliation, the other is to understand the customer's situation and demand points.

However, after he visited all the Zhangjia cooperative branches, Zhu Zilong found something in the cooperative pharmacy, which was very surprising.

The modern medicine commonly used in pharmacies on consignment is the most sold with Viagra. Of course, if you really think about it, this is not too much, after all, in an era where polygamy can be allowed, it is normal for rich people to buy more viagra.

But, but, but, it's important to say three times before people are speechless.

According to the reply of the pharmacy shopkeeper, the person who buys viagra the most from Nima is a eunuch. I'm dizzy!

That's right, the kind of eunuchs who should be present in the palace and the palace to serve the royal family.

Of course, there are only two possibilities for a eunuch to appear here. One is the eunuchs in the palace of the king of Shandong, and the other is the eunuchs arranged by the court and the emperor to guard the various prefectures.

But, either way.

The main force consuming viagra is the eunuch comrades who have been cleansed, which is too unreasonable and unscientific, right?

As a modern person, Zhu Zilong feels completely incomprehensible.
