However, the navy is currently building and training ships, so it is not suitable for large-scale naval warfare, and the development of Borneo has only just begun, and it cannot meet the logistical supply needs during the war.

In the days that followed, storms were brewing across the mainland, and the Ryukyus were busy resettlement, building new ships, manufacturing new weapons, and training new troops.

At present, the Ryukyu army plus the number of people who serve the country and the royal family are more than 800,000, and even if each person is rewarded with five kan, it will take 4 million kan, and the Ryukyus have also adopted their own calculation method.

The Great Song Dynasty money system is notoriously chaotic, not only the copper coins circulating in various places have different copper contents, and even the circulation of iron money and tin and lead money in various places, and how much money is a penny is also messy, the reason why the Great Song Dynasty specially stipulates that 770 Wen is consistent, is to feel that the money system is chaotic.

But the reform is not so simple, the commerce of the Great Song Dynasty is too developed, so the copper gap is very large, so the imperial court simply ordered that each place change according to its own needs, Zhang San used to mix Tokyo, that was at the feet of the Son of Heaven, and the private money in various places was relatively small, so I didn't think it was anything.

However, since the Ryukyus began to mint copper coins on their own, many unexpected things have happened, and the copper content of Ryukyu money is very high, and Ryukyu has no shortage of copper anyway, so Ryukyu money began to circulate everywhere.

As a result, the money of the Ryukyus could not be recovered when it arrived in various places, which was the so-called phenomenon of bad money driving out good money, and Zhang San could also understand that in order to facilitate merchants from all over the country to trade in the Ryukyus, Zhang San specially set up banks in Tamsui Taichung and Tainan, allowing merchants to exchange copper coins for copper coins in their hands.

As a result, this policy was stopped by Qian Jin not long after it was implemented, and there was a special money dumping business on Ryukyu Island, because Zhang San implemented a free commodity economy, and the Ryukyuan people also used Ryukyu money, so the value of Ryukyu coins in Ryukyu was basically the same as that of Song money in the Great Song Dynasty.

Then the problem comes, the Ryukyu money contains nine copper, and the Song money contains only six or six .5 copper, so there are two or three layers of profits directly in it, so some merchants began to use Song money to buy Ryukyu copperware, copper coins and other things, and shipped them back to the Great Song Dynasty to make profits by casting Song money.

In order to facilitate the trade of merchants, Zhang San did not prohibit private individuals from exchanging Song money for Ryukyu copper coins, so in this way, many people simply went to the bank to exchange, and Qian Jin, as the minister of commerce and trade, was the first to discover this phenomenon and immediately ordered the bank to stop this exchange.

Qian Jin reported this matter to Zhang San, Zhang San was also half dead of anger, isn't this equivalent to, these guys take money directly from their own pockets, transport the Great Song copper coins from the Great Song Dynasty, and transport the Ryukyu copper coins from Ryukyu, this kind of trade, Ryukyu is not beneficial at all.

But this matter cannot be stopped, otherwise the people will suffer the most, because there is still a lot of Song money circulating in Ryukyu, Zhang San had to strengthen the control of the bank, and carried out a month-long exchange activity.

Zhang San first ordered the collection of taxes and Zhang San's own shop to continue to admit the use of Song money for a period of one month, and if anyone did not use it up within a month, then the Song money would no longer be exchanged.

After that, Zhang San stipulated that the merchants who came to do business could only settle the Ryukyu copper coins with the goods, which of course did not include the Great Song Dynasty copper coins, and they would pull things over if they wanted money, so that if anyone saw the profits in it, he had to pull the goods over to exchange, and could not use the worthless Great Song Dynasty copper coins for exchange.

After such a reform, Zhang San finally lost more than 2 million guan through settlement, which was still discovered in time, and caught up with the war to restrict trade with the Great Song Dynasty, if it was in the evening for a few months, Zhang San lost tens of millions of guan.

This is half dead to Zhang San's anger, not only collected a lot of waste money, melted and wasted manpower and material resources, the key is that this loss is too aggrieved, Zhang San also considered whether to arrest the participants and let them spit out the money.

But thinking about it, people don't break the law, and you don't have regulations to prevent you from doing this, the impact of Ryukyu is now engaging in investment promotion and arresting people is too bad, so Zhang San swallowed this breath.

However, it is not without benefits, after this incident, the Ryukyu Kingdom not only established an image of integrity, but also gave everyone the impression that everyone is stupid and has a quick money, which has a great effect on economic development.

In order to make up for this loss, Zhang San planned to start developing Iwami Silver Mountain after the year, and the east wall lost and the west wall was compensated, of course, Zhang San also wanted to reserve a batch of gold and silver to cope with the next currency reform.

Zhang San has always had a banknote dream, but this dream has been pitted by pig teammates, Zhang San's current banknotes are produced, but the circulation is indeed several twists and turns, in order to stabilize the value of banknotes, Zhang San not only opened the bank banknotes and copper money exchange business at any time.

He also ordered merchants everywhere not to refuse to accept paper money, and even set an example, Zhang San's shops all accept paper money, and taxes and other things are also paper money priority, but Zhang San spent so much effort to make the promotion of paper money a little better.

The Jiaozi on the side of the Great Song Dynasty began to depreciate wildly, and the Great Song Dynasty even issued a holy decree to force Yuan You's previous Jiaozi to be invalidated, and the depreciation of Jiaozi caused everyone to hide the copper coins and use Jiaozi.

Because everyone thought that this thing was becoming less and less valuable, and they had to spend it quickly, so the Great Song Dynasty was now full of Jiaozi and no one collected it, and the Great Song Dynasty couldn't collect copper money when it collected taxes by itself.

When Cai Jing and other waste materials saw this, they simply forced the people to pay more than seventy percent of the taxes with copper coins, and the rest could be used with jiaozi, and reduced the exchange ratio between jiaozi and copper coins to the price of two jiaozi.

This self-depreciation behavior directly led to the collapse of the credit of the Great Song Jiaozi, which indirectly led to the issuance of Ryukyu banknotes was blocked for a time, and everyone lost confidence in paper money. During that time, Zhang San even had a run on various exchange points in the Ryukyus.

Fortunately, Zhang San prepared Jiaozi reserves, and ordered copper mines and smelters to increase production capacity, so that they could get through safely, but after this, the craze for Ryukyu banknotes also began to cool down.

It's okay in the Ryukyus, after all, Zhang San admits to giving exchange, but after leaving the Ryukyus and going to the Great Song Dynasty, no one dares to accept it, and everyone is also scared by Jiaozi, of course Zhang San will not give up so easily.

Therefore, Zhang San planned to change the copper coin standard of the Ryukyus to the gold and silver standard, so that the gold and silver as the intermediate currency would be in line with the copper coins of the Great Song Dynasty again, so that he would no longer be afraid of the impact of inflation in the Great Song Dynasty on the Ryukyus.

But the gold is okay, after all, the freshwater copper mine, and the central Luzon copper mine have gold companions, and now it can also bring Zhang San a share of gold output every year, of course, with the current smelting technology, the output is also very limited, the two places combined, only five or six tons of output a year.
