After instructing Cai Jian, Wu Yingying turned back to Xiao Jiu and said, "General Xiao, you just reply to him like this." From the Western Regions to Jinling, everyone knows the rules of the master and apprentice of the workshop guild in various places, and which family accepts the apprentice does not have to serve the master for seventeen or eighteen years before he can learn the craft. I'm a good craftsman in Anxi, and this apprentice is paid for ten years. If there is any new way to make money on Lao Kang's side in the future, my Anxi Army's craftsmen will also pay him for his apprenticeship. ”

With the current profits of woolen clothing, there is nothing to charge the patent money of 200 copper coins, the key is to let the businessmen led by Kangqu Dagan accept this rule, and at the same time, the existence of patent money makes the authorized merchants not vicious bidding lead to a rapid decline in sweater profits. The big businessmen who accept Wu Yingying's patent concept will naturally spare no effort to squeeze out those businessmen who imitate sweaters without authorization, at least within the reach of Wu Yingying and these big businessmen, infringing imitations cannot be popular.

The patent system is the treasure to promote technological innovation, in the era when everyone arbitrarily encroaches on the innovation achievements of others, people either stick to the old ways, or cherish themselves, and the technological level of the whole society is slowly improved like a snail, but after the implementation of the patent system, the creation of inventions and the improvement of production processes can greatly improve the speed of individual accumulation of wealth and social status. Although Wu Yingying could not control the infringement and imitation in Song Liao and other countries, he only profited from patent rights within the control of the Anxi Army, and the wealth obtained was enough to stimulate people's minds. What's more, the guild system and the tradition of apprenticeship in this era restricted other craftsmen from imitating the skills of others at will.

"Captain Cai, how is the matter of minting coins?" After explaining the most important military system and operating rules, as well as the various subtleties of the patent system, to the third general in detail, Wu Yingying began to care about other items in the craftsman's camp.

"According to the instructions of the adults, the mold has been made, and now it is able to press gold and silver coins and copper coins. As Cai Jian spoke, he took out a few coins from his arms and handed them to Wu Yingying, who only kept one of them in his hand to look at, and gave the others to Xiao Jiu and Zhang Zhongyao to watch.

The front of the gold coin made by the craftsman camp is a coiled dragon pattern, and the back has the year of minting and the words "one or two gold", because a little other metal components are added, it is harder and more wear-resistant than pure gold, and it is also more shiny. The same is true for silver and copper coins, which bear the words "one tael of silver" and "one tael of bronze" respectively.

This coinage was directly ordered by Wu Yingying to Cai Jian to do it, Zhang Zhongyao and Xiao Jiu did not know, they were a little surprised to see this situation, Zhang Zhongyao even thought that it seemed that the adults were bent on changing the dynasty, but they heard Wu Yingying say: "After the craftsman camps in Hexi, we must set up a minting yard as soon as possible, and then pay the money from the grassland tribes and traders, and try to use our own coinage." Since we occupy Hexi, the trade between the East and the West is so large, if we can all pass the gold, silver and copper dollars minted by the Wu'an Western Army, the annual coinage income will not be a small amount. ”

Rubbing the exquisite coins in his hand, Wu Yingying couldn't help but feel a little emotional, the trade pattern between the East and the West in this era is very different from the Ming and Qing dynasties, not only the West imported a large number of silk porcelain and other exquisite products from the Central Plains and Khitan, but also imported a large number of spices, gems, horses and various artifacts from the West, in general, the trade between the East and the West is balanced. That is to say, the Chinese in earlier times had considerable spending power, and they also bought large quantities of goods from the West.

After the Qing Dynasty, perhaps there was some kind of change in China's social structure, in short, the consumption power of the Chinese plummeted, and in the Qing Dynasty, the continuous surplus concentrated 75% of the world's silver in the hands of the old empire. While bacon and afternoon tea became the norm on the dining tables of English peasants, the living standards of the people of the Celestial Empire were at the low end of the previous dynasties, and it became a country described by barbarian envoys as a country full of beggars running on the streets, which was the so-called prosperous Kangqian era. The last war because of trade and the century-old national disaster swept away the huge surplus silver accumulated by the people for hundreds of years.

However, what is strange is that, judging from the records of the dynasties, in the trade between the East and the West, China's precious metals and coins flowed out in large quantities, so all dynasties and dynasties had regulations prohibiting coins from leaving the country, that is, from the perspective of metal currency, the dynasties recorded a huge deficit. However, judging from the records of Rome and Persia during the same period, there was also a large amount of gold and other precious metals flowing out to the east, that is, the western countries also had a huge deficit. So, where did such a huge amount of precious metals go, Wu Yingying estimated that they were all earned by those commercial cities that specialized in East-West trade in this era.

A Silk Road has nourished hundreds of the most brilliant and wealthy commercial ancient cities, including Luoyang, Taiyuan, Xi'an, Jiayuguan, Dunhuang, Gaochang, Jiaohe, Loulan, Turpan, Urumqi, Yining, Kuqa, Aksu, Kashgar and so on. In West Asia and Europe, there are Tashkurgan, Fort ***, Kabul, Mashhad, Tehran, Baghdad, Damascus, Constantinople, Lyon, Rome, Venice, Genoa, etc. It was getting late, and Wu Yingying explained everything clearly, and he walked into Huang Wen's boudoir quite apologetically. I saw that the candlelight was dim, and the daughter was already asleep in the small bed, and the pretty figure was leaning on the side of the baby's bed, with her head buried in her arms, as if she was unconsciously asleep when she was looking at the child.

Wu Yingying tiptoed behind her, a faint fragrance of hair fat into his nose, he gently hugged the delicate body into his arms, and was about to make love, the delicate body suddenly stiffened, and then broke free from his arms with an exclamation, Zhou Hou stepped back, while combing some scattered hair locks with his hands, his face was flushed, and he looked at Wu Yingying with anger.

Wu Yingying was speechless, stood on the ground at a loss, and said expectantly: "How can you... , I thought..."He originally planned to rescue Cai Yu, who had a favor for him, from Jinling, and paid great attention to whether he had anything to do with Zhou Hou, but who knew that something went wrong. If you are misunderstood about your widow's illness after this week, it will be a great wrong.
