After all, Cai Jing is an old fox, only proud for a short time before flying back from the sky, said to Jiang De, "However, if all the government in the world scatters money to the people, overhaul the official office, water conservancy, palace, garden, then the homeless people have money, as you said in your letter, the homeless people must consume if they have money, and the store will consume again if they have money, so that the cycle will be cycled, and the court will draw profits from it, then the world will be more and more full of government treasury, which can be described as "Feng, Heng"; The palace, the official office and even the people's housing will become wider and wider, which can be described as "Yu and big"! Saying that, Cai Jing turned his head and said, "But the world is restless, especially the western thieves peeping and continuing to spend on the military, Jiang Xiaolang said in the letter that there are three strategies to gather wealth for the country, is it true?" ”

Jiang De smiled, nodded to Cai Jing and said, "It's really serious." ”

Cai Qian first said suspiciously, "Jiang Xiaolang was the first to say that glass mirror, but what gift did you give to the Taishi?" It is indeed crystal clear, ingenious, but I have read all the books, I have not heard of this thing, and I heard you say that it is an overseas treasure, it must not be easy to obtain, how can I gather wealth? ”

Jiang De glanced back at Xu Guanzhong, and Xu Guanzhong said, "Taishi, do you know what is in those treasure chests that Yang Neiguan brought into the palace today?" ”

Cai Jing was excited, opened his mouth and said, "Could it be that the glass mirror?" ”

Xu Guanzhong nodded and said, "Yes, this glass mirror is indeed an overseas treasure, but it is like glass, as long as you know the secret of the process, although it is not easy to manufacture, it can also be done." My lord had already purchased the mystery with a large sum of money, and what was given to the palace was the stock that the overseas master had sold to my lord to prove that what he said was true. ”

Cai Qian asked, "Jiang Xiaolang, how much confidence do you have to make a mirror?" ”

Jiang De stretched out his hands and said, "Ten percent!" He also said, "Fourth uncle, rest assured, my Song people are the smartest people in the world, can it be that overseas masters can make it, but my Song people can't make it?" What's more, I have bought a lot of money to make mysteries, I have been in the Song Dynasty for a hundred years, and there are a lot of rich people, and these rich people bury gold, silver and copper coins in the ground, so that my Song Dynasty has a shortage of money every year, in order to let these rich people come up with money, this glass mirror is an excellent thing. ”

Cai Jing nodded clearly, if this glass mirror can really be manufactured in large quantities, then it can be sold to those rich families at a high price, how many rich families in the Great Song Dynasty are, no one can say, how much money these rich families have, no one can say clearly, but the only thing that is certain is that the money buried in the ground by these rich families must be many times more than the money in the treasury.

Cai Jing asked again: "The second treasure you said is silk cotton?" This thing is indeed beneficial to the country, where in the world does not persuade mulberry hemp? How to revive? ”

Jiang De listened, he knew that Cai Jing was misunderstood, in fact, this is normal, before the Song Dynasty in China, although China already had cotton, but more as an ornamental plant, "Liang Shu Gaochang Biography" recorded: its land has "grass, really like a cocoon, the cocoon silk like a fine silk, named white stacks." “

At this time, the cotton is actually cotton, that is, silk fabric, the Song Dynasty Chengping for a hundred years, the population breeds, the demand for cotton is also very large, the official silk cotton income of the Song Dynasty Shenzong is nearly six million taels.

Due to the low weaving technology in ancient times, clothes are easy to wear, especially fragile silk, which needs to be replaced every year, which makes the price of silk cotton high. The price of silk cotton is high, and the people are willing to raise silkworms and weave cloth, but they still can't meet the needs of the people, so the people wear more linen clothes every day.

Therefore, although Cai Jing is very interested in the interests of silk cotton, he also knows that all places attach importance to this matter, and persuading farmers to do so is also a compulsory course for the government every year, and there is nothing to strengthen.

Jiang De gestured to Xu Guanzhong, Xu Guanzhong walked to the back, and after a while, he took out a small box, Jiang De said, "Master Taishi, the kid said that kapok is not mulberry, but this thing." ”

Saying that, Xu Guanzhong opened the box, and Cai Jing and the others looked at it, only to see a white thing like a silk cocoon, which looked light and fluttering, and it was very good-looking.

Cai Jingqi said: "What is this?" As he spoke, he picked up a ball and looked at it in front of him for a while, before he suddenly realized, "Could this be the white stack?" So you're talking about this kapok! ”

Jiang De clapped his hands and said, "The Taishi is really well-read and has a strong memory, this is the white stack, the Taishi actually knows this thing, and he must also know that this thing can be woven, right?" ”

Cai Jing smiled: "Jiang Xiaolang is testing me." ”

Cai Qian stretched out his hand and said, "Daddy said so, I also know this thing, "Liang Shu Northwest Zhurong Biography" has a saying: Gaochang country, many plants and trees, grass is like a cocoon, the cocoon is like a fine silk, the name is white stacks, and the people take more weaving as cloth. The cloth is very soft and white, and it is used in the market, which is what it is. ”

Jiang De couldn't help but admire the literary literacy of these ancient literati again, and those who wanted to use a few sentences of Tang and Song poems to pretend to be B in ancient times didn't want to think about what kind of existence these ancient literati were. Usually speak and quote scriptures, and give you a large section of the original text at every turn? I'm afraid that it will be discovered by others in less than half a day that it is actually an embroidered pillow, and the poems made are also plagiarized.

Cai Jing said to Cai Qian with satisfaction: "This is it!" ”

Xu Guanzhong also clapped his hands and shouted: "Master Cai really has the style of a master!" ”

Jiang De went on to say, "As soon as the Taishi tried it, he knew that this thing was extremely warm, such as weaving cotton cloth, strong and durable, and cotton was more than that of silkworms, without the labor of picking and raising, and it had the effect of harvesting; The ramie of the city, the work of exempting from the performance of the arrest, get the benefit of the cold, can be described as not hemp and cloth, not cocoon and flocculent, and do not pick up water and soil, the east and west, north and south can be planted, such as the Taishi Daxing this thing, its benefits can not be estimated, not to mention the bitter cold in the north, the Liao people are in urgent need of warm things, we can sell this thing in the north, in exchange for cattle and horses, and then sell to the rich, and get a profit! ”

Cai Jing took a breath and said in disbelief, "Is this thing really so good?" ”

Jiang De nodded, shook his head again, and said, "It's just that the good seed of this white stack is hard to find, and I'm afraid it will take some effort from the master." ”

Cai Jing stroked his beard and smiled, "Do you know that the old man and the official family like these strange flowers and plants the most, this white stack is in the old man's house, and there are also in the Yanfu Palace of the official family, and I also know that the white stacks in the Yanfu Palace of the official family are the different species obtained from Fusang in the past Liang Guo, the flowers are big and white, and they are extremely beautiful." ”

Fuso? Japan? Jiang De blinked, he hadn't heard that Japan was still the origin of cotton, wasn't the cotton of the Song Dynasty from India? How does it sound that Japanese cotton is better than India's?

Thinking of it, Jiang De asked, "Is this Fuso Japan in the east?" ”

Cai Jing was stunned for a moment, glanced at Cai Qian, and then laughed together, Xu Guanzhong next to him was also a little embarrassed, and said to Jiang De, "Lord, the Fusang on this "Book of Liang" is not Japan, Fusang and Wa are listed separately, according to the "Dongyi Biography" record, Fusang is more than 20,000 miles east of the Han Kingdom, and it is located in the east of China. Its soil is full of Fusang wood, so it is named. The Great Han Kingdom is more than 5,000 miles east of the tattoo country; And the tattoo country is more than 7,000 miles northeast of the Wa Kingdom, so if you calculate it, in fact, Fusang Country is 30,000 or 40,000 miles away from my Great Song Dynasty. ”

When Jiang De heard this, his eyes were about to fall out, forty thousand miles? Where is that? Later generations will know that it is America! In this way, it is clear that this heterogeneous species from Fusang is probably American cotton, although Jiang De can't understand how the people of the Northern and Southern Dynasties can come to the Americas, but no matter what, it is a great thing to find American cotton, after all, whether it is African cotton or Asian cotton, it is not as high as the yield of American cotton.
