In fact, there are not too many unique commodities in the country, and the country and the country are roughly in one dimension, and the country basically has the country of salt, on the contrary, the country has a huge demand for pig iron, steel, copperware, cloth and other products needed by the country every year, but the population of the country is more than 3 million, and the consumption and capital output are also limited, and most of the domestic precious metal hard currency is exported to the country in trade activities, and the economic potential has been greatly weakened, so the country is destined to be a trade deficit country.

The only way to improve the economic strength of the country in the short term is to transfuse the economy and expand the import of goods from the country.

However, considering that the sea route is too far and the productivity is low, ordinary raw materials will lose their competitiveness with other countries due to freight costs, and it is not easy to find suitable imported goods from the country.

The most immediate effect is to forcibly peg the copper coins of the country of Qi to the new currency of the country of Xian at an exchange rate favorable to the country, so that the goods exported from the country of Xian to the country will be much lower because of the exchange rate, and the country can benefit from it as an outer country of the country in the West Sea, and at the same time, Bailiyan will be exported to the country at a lower price, further diluting the loss of freight and exchange rate, and the country will benefit from this.

Set the policy, the three of them set out to quantify the plan, but how to increase the import of goods from the disguising country is still bothering Bailiyan, it is obvious that he can't know that it is unprofitable, and forcibly increase imports to harm his own interests, and the money is not posted upside down in this way.

So after the next day, Bailiyan found Ding Su for details.

Ding Su and his children have been running around the world for many years to open up the West Sea for Bailiyan, and Bailiyan does not treat him badly, giving him a large number of commercial goods for him to sell every year, and the tax department also greets him and gives him more tax benefits.

Now that Ding Su is old, he has been nesting in Chenling to care for his great-grandchildren after returning from the West Sea a few years ago, and the business has been handed over to his children and grandchildren to take care of.

"Ding Caidong, it's been good lately."

"Thanks to the Hou Ye, everything is fine. It's that my children and grandchildren are away all the year round, and I can't rest assured that this old bone is here. ”

"Yes, being a parent always has a concern that you can't let go. If there is a chance in the future, how about Ben Hou give your children and grandchildren a fat difference. ”

"Hi...... Now the old man's family is rich, and he still cares about the fat difference of that official and half-position. Hou Ye and Zai Xia both escaped from the pile of dead people together, and they have reached my age, with such wealth, no amount of gold and silver can be exchanged for a few more days of life. Forget it, the old man's son and the old man know that he is not the material for being an official......"

Ding Su pushed away his good intentions, and faintly made Bai Liyan feel that Ding Su had encountered the political turmoil caused by the change of power after the crown prince ascended the throne, and he didn't want to be implicated because of this.

Thinking of this, Bai Liyan was not angry because of this, and instead said:

"Ding Caidong, I came here today to ask for advice, and I hope Ding Caidong will tell you the truth."

"Master Hou is serious, as long as the old man knows, he will know everything. I don't know what Master Hou asked? ”

"Presumably Ding Caidong also knows that my Xianguo has always sold more goods to Qiguo and bought less goods. I would like to ask Ding Caidong, what unique commodities can be found in the country that our Xianguo does not have? ”

"So that's the case, this old man has to think about it when the time comes......" Ding Su sat cross-legged with his old dragon clock, hunched over and thinking hard, and said after a while: "Speaking of which, the old man has been to Qiguo many times and understands, but the climate of Qiguo is roughly similar to that of my Xianguo, so I also have all the things in Xianguo, and there are so many things that are indispensable in Xianguo, one is the dyes of Qiguo, the second is glue paint, and the third is cables and fishing nets, these three things are beyond the reach of my Xianguo." ”

"I have heard of the glue paint of the country, there are three beauties in the world, the women of the country, the dyes of the country, and the glue paint of the country, the glue paint is unparalleled in the world, and the glue paint used in the palace is produced in the country. However, the price of this kind of rubber paint is very small, and it is not enough to buy it in large quantities, so it is difficult to make it bigger. Ding Caidong knows why? ”

"I don't know why the old man is not clear, but does the Hou Ye know why most of the dyes in the country of Qiguo can't be sold in my Xianguo?"

When Ding Caidong said this, he remembered that half of the dyes used by Ruitian needed to be imported from abroad, but there were no Qiguo dyes. It is said that the dyes of Qiguo are the best in the world, but their distance is far away, and even if they are transported to Xianguo, the price is estimated to be not cheap. ”

"This is one thing, and the other is that the dyes of this country are made of flowers and plants, and they cannot be stored for a long time. If you cross the sea by boat, its discoloration will change faster, and if you can't wait to go ashore, it will all turn black and green, and it is difficult to use it again.

Therefore, the dyes of Qiguo are used in the West Sea, and it is even difficult to enter the territory of the country, precisely because it is difficult to preserve. ”

As he spoke, Ding Su called his subordinates to take a few pieces of silk and dyed cotton cloth from Xianguo and handed them to Bai Liyan and continued:

"Hou Ye, you see, this is the silk and dyed cotton cloth of Qiguo, its color is bright and fresh, and the feel is much softer than the same unexpectedly soft in my Central Plains and Xianguo."

"Well, indeed. The color is indeed beautiful, and this high-quality blue silk looks as gorgeous as a gemstone, could it be the effect of the dye? ”

"Exactly. This Qiguo dye is made of juice soaked in three ink grass, the first juice is the color of this royal blue, the second juice is added to the gills, which can be adjusted to bright red or smoke powder, and finally the third juice is mixed with the seeds of the three ink grass to grind into the powder, which can be adjusted to indigo, gray, and black. ”

"Then can I introduce the cultivation of the Three Ink Grass from the Miser Country for my use?" Bai Liyan asked.

"If I could, I would have stolen it a long time ago. This grass only grows in the city of Sanmo and the nearby county towns of Qiguo, and it is difficult to achieve miraculous results without this place. Previously, there were also princes who coveted the three ink grass and stole it and planted it, but they did not succeed.

In addition, the method of juicing and mixing the color of the three ink grass is only known to the domestic government, and even if outsiders get the three ink grass, it is useless. ”

Sanmo grass should be named after the city of Sanmo, which is a natural plant dye with strong coloring strength, not easy to decolorize, and has no irritation to the human body. The chemical components contained in Sanmo grass are extremely sensitive to temperature, and different temperatures react with different chemicals to produce different colors.

Because the Sanmo grass contains natural gum that is not easy to oxidize, the fabric dyed by the Sanmo grass is bright and supple in color, and the special gum is attached to the surface of the silk protein after combining with the silk protein, making the silk more resistant to corrosion and wear, and the storage time under static condition is longer and more durable.

Due to the long distance of Gikoku and the natural chemical components contained in clover that are prone to oxidation and deterioration in contact with salt spray and air, it is almost impossible for Kikoku's dyes to be shipped to the North Sea for sale.

At the same time, the productivity of the country was low, and the cost of silk fabrics and dyed cloth was much higher than that of the Central Plains, and the merchants of the Xian country were more inclined to buy the best quality silk fabrics from the Liang country and sell them into the country, because the Liang country was closer to the country and used more dyes from the country.

After thinking for a long time about the fabric of Qiguo, Bai Liyan suddenly asked:

"There's no other way to transport the dyes of the country to the country of Xian?"

"I'm afraid it's difficult, if it can be transported, it would have been shipped a long time ago, isn't it discolored halfway."

"Then let's do it, Ding Caidong should have a foreign port in Qiguo."

"Yes, what are the instructions of the Hou Ye on the sea route to Chen Guo through Qiguo?"

"You first let people know that you will be in the outer port of Qiguo, and only buy a hundred stone of Qiguo Sanmo Grass Dye, remember, buy some of all colors, and make up a hundred stones. After the official ship of Xianguo arrived in Qiguo, he placed an order to buy fresh dyes. At that time, there will be copper skin and copper on the ship, and all the dyes can be poured into the copper barrel, and the rest will be in charge of Ben Hou. ”

"Master Hou, you really want to be lucky."

"Well, you don't have to worry about Ding Caidong, if it can be done this time, the purchase of dyes in the future will be handed over to Ding Caidong."

"Eh, the amount of dyes in the government every year is huge, and in the future, Ruitian will expand the dyeing cloth, and there will be a lot of dyes in the country. The old man didn't help with anything, so he had such a business for nothing, which is really inappropriate. ”

"There's nothing wrong with it, how to decide this matter, and the money will come out of the department store."

"Well, the old man wrote a letter today and sent someone to send it to Qiguo to do it as soon as possible."

Cotton cloth woven from cotton yarn still needs to be dyed and sold, although there is no floral cloth at the moment, but the quality of the color and the quality of the cloth still affect the sales of the cloth.

At present, the dyeing is dominated by colored mineral stones and plant dyes, such as copper sulfate is a common blue dye. The coloring difference of ore dyes is often slightly toxic, and the trace toxicity is basically ignored at the moment when the technology is not developed, but the ore dyes are easy to produce and easy to use, and the ingredients are stable and not easy to change color, but they will fade and fade, but they are suitable for mass production and use.

Plant dyes need to be planted and harvested in large quantities, which consumes a lot of arable land and labor, and at the same time, extracting plant dyes requires grinding and hot water to boil, which consumes a lot of manpower and man-hours, so the cost is higher than that of common mineral dyes.

At the same time, the chemical composition of plant dyes is not stable, and it is easy to react with the oxygen in the air to change color, so plant dyes or dry powder are preserved, and most of the liquid dyes that cannot be dried and preserved are obtained and used nearby, and can also be stored in large tile jars and suffocated with wooden cover stones, so as to avoid contact with air as much as possible.

The shelf life of the dyes is much shorter than that of other liquid plant dyes, which means that the chemical components contained in them are more likely to combine with oxygen and salt spray at sea and change color, while the sealed copper poke with stamping and enamel is used to transport the dye, which can eliminate the erosion of oxygen and salt spray.

After finalizing the matter of dyes with Ding Su, Bai Liyan learned in detail about Qiguo's cable fishing nets and glue paint.

In addition to dyes, a special kind of hemp silk is a special kind of hemp silk, which is actually a kind of tree palm, which is more than three meters long and has a tough and tenacious texture, which is often used to make boat cables and large fishing nets, and is also used to make bowstrings.

Although things are good, they are the same as Sanmo grass, and the difference in climate and environment is difficult to introduce and plant, only Xihai Qiguo and Chen Guo produce, and there is almost no possibility of improving and introducing the current technology.

Due to the fact that there are other products that meet the performance in China, the Xianguo government rarely introduces this kind of hemp silk products. However, in the future, the use of large sailboats, the requirements of the rope will be further increased, and the traditional rope can only achieve strength by increasing the performance of the continuous thickening, so that it will undoubtedly become heavier, and the use of the rope with better texture performance will reduce the weight more.
