Late November. The big rivers and the Bohai Sea were frozen one after another. However, the giant horse water is still green and flowing to the east.

The second department of the capital ship and the capital water department allocated manpower. Stagger the heating peak, open the valve at the right time, and inject hot springs to heat up the river.

Ship merchants from all over the world, rushed before the ice, and returned with a full load. Thistle domestic river shipping, but enduring. Pick up and drop off personnel and materials from various cities. Transporting grain to various city warehouses and military camps is the most important thing. Winter construction, the thistle country can be skilled craftsmen, has long been familiar. The materials are complete and the manpower is sufficient. The large construction of the serval is just right.

The five sons of the Chen family are all the heads of a county. He supervised the construction of the cities under his rule. Before they came out, the five of them were already interns and were quite familiar with political affairs. In addition, it is Cui Yu and Liu Chong's senior disciples. There is also experience in governing the government and securing the people.

Near the sea, there is a thick ice. Especially in Changlu and Changting counties. Horse-drawn carriages are equipped with sleds and travel to and from the ice. Transportation of gravel, large wood, bricks and tiles. As Liu Bei said, build the city first, and then build the embankment. Prevent seawater backflow. When the land is dried, take the silt of the northern serval to pave the ground, which can be fertile land. The coastal sea is mostly salted, and if the barren land cannot be fertile land, it will be turned into a "salt pan".

Sea salt, originally prepared, is the "frying" and "boiling" method, with a plate for frying, with a pot called boiling. History says "boiling the sea as salt". "Pipe" contains: "At the beginning of late spring, the people of Beihai boiled the sea for salt." "Zhou Li" also contains: "Youqili Fish Salt".

The "salt drying method" is also known as the "salt pan method". It's not often these days. This method requires the construction of salt pans in a place with a mild climate and plenty of sunshine, and a large flat beach. Changlu and Changting, both suitable.

Those who make a living by boiling salt are called "salt households". It is also a household and a common people. As for the method of making the salt pans, it is the same as usual. The hand-drawn drawing board of the king of this tle was handed over to the master craftsmen of the museum for their own understanding. The thistle king left a book on the board: "Salt pans like paddy fields." Draw seawater up the tidal flats and build dams to store them. Sunlight exposure, 'salt crystals' come out of their own eyes. ”

In Liu Bei's opinion. Whether it is decoction or drying, the principle is actually the same: "evaporation crystallization".

Direct introduction of seawater to make brine salt. In the later generations of Changlu salt area, "when the spring is warm, dig a ditch near the sea, wait for the tide to enter the ditch, and build a 'drying pool', nine or seven layers, from the height down. The tide recedes, the two ropes tie the 'willow bucket', the salty water of the ditch enters the first layer of the pool, fills it with the sun, and then puts it into the second pool, and then fills the highland again, and at the end of the second release, votes the 'stone lotus' to try it, salty, so it takes advantage of the sunny day to expose 'one day into salt'. ”

"Drying ponds" are analogous to terraced rice fields. It refers to the salt pans that are built layer by layer from the bottom of the beach to the top of the beach. Adapt to the situation and adapt measures to local conditions. There are seven or nine floors.

The king of thistles dances wildly, and he will not dare to slack off. Immediately began to develop the art of drying salt.

The good craftsman was ordered to take the seawater and send it to the glazed warm pavilion. Packed into a checkered box, taking advantage of the warm winter sun, exposed to the sun for days. Fruit to see salt crystals.

Xia Gong, Su Bo, and even the master craftsmen in the museum were all overjoyed. The country of Ji first had paddy fields, and then there were salt pans. How can it not prosper.

The Lord of the Book and Newspaper. Liu Bei was overjoyed. This ordered the Planning Department to go to Changlu and Changting counties to measure and estimate on the spot.

Returns in the future.

Words: Three hundred miles of tidal flats can open up millions of acres of salt fields. Roughly calculated, you may be able to get salt, 10 million stones.

In the Han Dynasty, the lowest price of salt was 400 yuan per stone, and the highest was 8,000 yuan per stone. In a normal year, the price of salt is about 800 yuan per stone. Nowadays, it's only high, not low. If you count it at 800 yuan per stone, you can get 8 billion yuan.

Liu Bei finally understood what "the benefits of fishing and salt" were.

The so-called "endowment of the world, salt profit is half". After the construction of the two counties of Yantian is completed, the country of Ji will not only be rich in the world.

The point is. Except for labor, there is almost no cost to drying salt.

Chen Yi said again: I asked the fisherman in the serval, and the sun in Bohai Bay is sufficient. When it is full, one million salt pans can get 16 million stones of salt a year.

Far more than the estimate of 10 million stone in the book and newspaper.

If it is really as stated in the above order, it is "tens of billions of profits".

Other words. Each acre of salt field has an annual output of 16 stone of salt. The price of salt is higher than the price of grain. The salt yield is higher than the field yield. Yongnu is really the pearl of the Bohai Sea. It is of great benefit to the people.

I heard that in the two counties of Changlu and Changting, the salted beaches with no grass for 300 miles can be split out of millions of acres of salt pans. The yield per mu is 16 stones, and the annual income can be 12 billion yuan.

It's worth it.

The two ministers hurriedly dispatched manpower. Go to the second county and reclaim the sea to make fields.

Who would have thought. The yield per mu of salt fields is nearly three times that of paddy fields. And the price of salt is three times the price of grain. Such a huge profit actually comes from a beach where there is no grass. Although the two prime ministers will be skeptical, they are full of expectations. In a few months, it will be clear.

The country of thistle is a great cause. The left branch is weak, and the little adds up. The pen and pen are astronomical. Especially the Longyou migrating Qiang people. If the four-year period expires, he is unwilling to stay in the prison city anymore and returns to the village with Yongjin. How to pay for the huge amount of money is a heavy burden on the hearts of the two countries.

The point is, farming doesn't make a fortune.

And the king shall not raise the price of grain. There is a shortage of food in the world, and strange goods can live. but still the price was three hundred thistles. Raw materials are also required for coinage. Whether it is the smelting and mining of copper ingots in the Dongling Mine, or the new minting of old coins of the two Han Dynasty, they are subject to the time limit.

Now I suddenly heard that there are tens of billions of profits, lying in the bay of the Bohai Sea.

Barren land can solve urgent needs. How can you not be ecstatic.

Liu Bei was also taken aback. It is only known that the later generations of Changlu Salt Farm are very famous. The salt produced in Lutai can be called a good product of sea salt. The color is white, the grain is large, the quality is firm, and the flavor is original, so it is called "Lutai jade sand".

I didn't know that the yield was so high. One acre of salt field can get 16 stone of salt per year.

Sure enough, God helped me.

Not surprisingly, "thistle salt" should be followed by "thistle tea", "thrips", "thistle book", "thistle iron" and so on, becoming a new famous product of the Silk Road.

In December, Ji Si, pardon the world, and change the yuan to "Zhongping".

It is called the first year of Zhongping.

Although the matter of Yantian has not been made public. However, the country of thistle is up and down, and there are rumors. The thistle king's heavenly unicorn, the law of the salt field, is out of the hands of the king. And after the verification of the museum, there will be no difference.

However, millions of acres of salt fields, where do salt households come from?

In fact, nowadays salt people fry salt, which is quite hard.

From salt production to sales, later generations said that it had "four bitterness": "When it is drenched, the whole family appears on the stage, scrapes the mud and draws the sea, and sweats like rain." In the middle of winter, the skull will also be done, and this 'bitterness of drenching' is also. When cooking, it is scorched and fumigated, unkempt, and does not look like a human shape. The heat is like soup, and I dare not leave, and this 'bitterness of frying' is also. The cold and summer are cloudy and sunny, and there are lessons every day, the former is not enough, and the latter comes back, this 'salt suffering'. Merchants arrived, there was no salt to offset the price, hundreds of ends were humiliated, and the whole family was worried, and this "salt loss" was also. Death from illness is especially unbearable. If you flee, your body will be lost, and if you resume business, your family will be ruined, and you will be in a dilemma, and you will have no way to live......"

Thistle farming, in fact, is not bitter. From cultivation to harvesting, there are animal power traps. However, Yantian is a start-up. First of all, it must be based on manpower. If it is calculated as one person and one acre, it should take millions of people. If one person is ten acres, he is also allowed 100,000 strong laborers.

Ji Guotai academic circle, the recent Bo Theory, will take this as the title: "On the Pros and Cons of Yantian".

The debaters on both sides quoted scriptures and classics, which was deafening. Again with the national politics, the students who audited the students woke up one after another.

One million three Koreas is the source of manpower.

The king's name is "Bei". Everything has always been ready, and sure enough, it is not surprising.
