The public official took someone to move the colored cotton from the car. Xu Ping ordered: "According to the previous instructions, you should try each one in the same way, don't get everything together, and you can't see what it looks like in the end."

The public official agreed and took the people to prepare.

Doing experiments is a technical job. From the beginning, what purpose should be achieved, how to arrange, how to deal with the results, and what conclusions to draw in the end, it is difficult for people who have not conducted relevant training to do it well.

Since the time when he decided to set up a money shop, Xu Ping set up this small factory to specialize in making various bills needed on Jingxi Road. All the paper used for bills is made by himself here, and various paper tests are carried out at the same time. If there is any paper to be used for issuing banknotes in the future, Xu Ping hopes to have an answer through the experiment here.

During this year, I almost tried it all from the commonly used mulberry paper such as Jiaozi in this era, namely paper made of mulberry bark, linen bark, linen rods, and even fishing nets. As for the commonly used rice paper, bamboo paper, let alone. In the end, Xu Ping found that the best raw material for paper money was cotton, especially the shortest cotton fibers attached to cotton seeds. The paper made was not only strong and durable, but also conducive to printing, and was also suitable for handling various anti-counterfeiting marks.

This is why Xu Ping asked Wang Gongchen to pay special attention to colored cotton. If the corresponding paper can be made from colored cotton, it can be used as a special paper for banknotes in the future. This alone greatly increases the cost of manufacturing counterfeit coins.

From the day the banknotes were produced, such as Jiaozi in Yizhou, counterfeit coins appeared. However, Jiaozi had a limited range of use and was easy to control in a relatively small range, and did not cause a particularly bad impact.

Paper money will basically not collapse because of counterfeit coins. The counterfeit coins only increase the cost of the banknote system. As long as the credit of the banknote does not collapse, counterfeit coins are just a disease of scabies. However, for banknote issuers, they always hope to offset the issuance and use costs brought by counterfeit coins at the minimum cost, thereby obtaining the greatest profit.

This is particularly important for Xu Ping. If paper currency is launched, the official profits will be lost or even negative, and the prospects of paper currency will be cast a shadow. It is precisely because of this that although Xu Ping still devotes great energy to know that anti-counterfeiting is not the key point of banknote issuance.

Seeing the public official taking people away, Wang Gongchen said curiously: "Why do Ducao think about making paper with cotton?"

"I'm trying it out! I'm not a god, how do you know which paper is the best? I have to try it out one by one. Over the past year, I've tried all the commonly used and uncommonly used paper materials here, and cotton is the best."

Wang Gongchen looked at the huge cotton bale and always felt that it was magical to turn into solid paper. He asked again: "Only use cotton?"

Xu Ping looked at Wang Gongchen and shook his head with a smile: "June, you don't need to ask this, you have to be suspicious!"

Wang Gongchen immediately understood that such an important thing is of course that the fewer people know the better. Maybe not many people in this small workshop know the recipe. But they were unhappy and dissatisfied: "I just asked casually, who wants to know this? I only asked Ducao, what should I do if the Sanshi Department does not allocate copper coins this year, what should I do if the land business debts are in debt? I have thousands of people under my command, but I have to rely on this money to make a living! How can I let everyone work if they are unhappy?"

"The money will definitely not be small, and you don't have to hurry at this moment. Wang Bowen, deputy envoy of Salt and Iron, just arrived in Xijing City and said he wanted to worship the imperial tomb. I think it was mostly for this matter. What happened depends on the news after he returned to Beijing."

Wang Gongchen's expression then eased a little, and he asked Xu Ping: "Du Cao, what can you think of Deputy Envoy Wang when he returns to the capital? Can he really create so many copper coins? I think it's still a bit uneasy!"

"June, copper coins are just one type of money, why do you only recognize this one? In the past, copper coins were not the same, and officials had to pay the salary, but they had to spend the same amount. Besides, in the past, money and silk were used up, but copper coins were not enough, and there were also a large amount of silk. Could it be that it was not the same? "

"Silver?" Wang Gongchen laughed after hearing Xu Ping's words, "Du Cao, don't go out and inquire. What is the price of silk now? In the past, a piece of silk cost only a few thousand and seven hundred cents now, who dares to ask for it? If this is collected for six thousand and seven hundred cents, it will become three thousand or four hundred cents a piece after a while, who can I ask for advice?"

Xu Ping smiled and said, "Who did you hear this? The price of silk on Jingxi Road has not dropped to that low."

"Yes, there are no Henan Prefecture and nearby prefectures and counties, but outside prefectures and counties have fallen! It is Jingxi Road, and the silk prices in Mengzhou and Xiangzhou have fallen as much as they are. I heard that all Jingxi Road prefectures strictly prevent the silk from being transported in from outside prefectures, which makes the price of silk not very much. If not, Henan Prefecture's silk prices will also fall by half!"

"Xiangzhou and Mengzhou do not implement the new policy, so of course they cannot be treated the same as other prefectures and counties on Jingxi Road. Their silk prices can only be comparable to those of the outside prefectures. And the silk prices on Jingxi Road cannot fall."

Wang Gongchen said strangely: "Why? The silk here is expensive, so there will always be someone who will transport it in and sell it!"

"I will collect heavy taxes when someone transports it in. See how much money they have to pay for it! Originally, the price of silk fell. Although there was a large number of cotton cloths on the market, it was even more difficult for the three departments to handle it properly, and it was a mess."

"What do you say? Can Sanshi force the price of silk to rise by force?"

"Why can't it be? The iron coins are transported across several roads in Chuanxia. I have used copper coins and iron coins in parallel before. Have you ever heard of the technique of raising them? It is because copper coins and iron coins are parallel to prevent them from being expensive and cheap."

Wang Gongchen thought about it and said, "It seems that he has heard of it, but he is not very clear."

"When there are two types of money, and when the price comparison is parallel, in order to prevent the two prices from being high and low, they should be called raising. In the Tang Dynasty, money and silk were used to force the government to stipulate the exchange ratio, which was not easy to use. What is really useful is to control the amount of money on the market, and then the official adjustment. The government will send more money when it is expensive, and collect some when it is cheap. These combined methods are called raising. Now, money and silk are also parallel on the market. When cotton is listed, the price of silk has fallen. According to the method of raising, the Sansi and local governments should buy silk and place copper coins to stabilize the price of silk. Although the price of silk will always fall after the popularity of cotton, it will not plummet like this, causing countless troubles. As a result, the price of silk has fallen now. The Sansi and local governments not only do not collect silk, but also take the lead in throwing out the silk from the warehouse. Isn't it okay to find trouble?"

Wang Gongchen was stunned and said, "Just as you said, Sansi is afraid that there is not so much money in his hands."
