At this time, Li Du naturally did not know the island where he led the Ming army fleet to station, which was later called Bataan Island.

It is only separated from Taiwan by the Bass Strait.

As there are still signs of piracy on the island.

The hundreds of officers and soldiers who landed on the island chose to set up camp at the foot of a gentle slope near the beach.

The Ming officers and soldiers who were in charge of receiving Lin Xu joined the wounded soldiers who had retreated halfway through.

After sending another person to escort the wounded soldiers back to the camp, they immediately followed.

When it was sunset, it was convenient for the two classes led by Lin Xu to converge.

Bataan is so large that it is impossible to explore it all in a short period of time with a few dozen people.

And the pirates were clearly hiding in the dense rainforest.

The ambush at noon also made the Ming army vigilant, and after groping to make sure that there was no trace of pirates, Lin Xu led two squads to retreat.

Presumably, the pirates hiding in the depths of the rainforest will not be discovered by the Ming army in a short time.

While the Ming army and pirates were playing peek-a-boo in the Batanes, a major event also happened to the Ming court in Luzon.

The Ming court of Laoag began to mint coins.

But to the surprise of all the Luzon Ming, the newly minted currency was not a brand new silver ingot, but a silver dollar.

This undoubtedly shook the officialdom and shopping malls of the Ming court in Luzon.

All this was naturally Liu Yu's idea, and after going south to Luzon, the Ming army, whether it was to exterminate the pirate chamber of commerce, seized coins or obtained coins through trade, were mainly Spanish silver yuan.

This also brought inconvenience to the conversion of the Ming army, after all, the Ming army and the mainland circulated silver taels and copper coins.

The silver dollar only entered China at the end of the 16th century, and before the Opium War, it was basically used as the plaything of scholars and doctors, and was not used as a currency in circulation.

It was not until the end of the Opium War that the Qing court ceded land and paid indemnities and exchanged silver for the silver yuan demanded by the British, and since then the silver yuan has gradually become a circulating currency with the arrival of Westerners on the mainland.

At this time, the Ming people still valued silver ingots, and they did not recognize the Spanish silver dollar.

After all, silver ingots in silver taels are not equivalent to Spanish silver yuan, and the conversion is also very troublesome.

When trading with the Four Seas Chamber of Commerce, the Ming army still calculated in two units of silver, while the currency in circulation in Nanyang was Spanish silver yuan, which was time-consuming and laborious to convert, which was enough to give the Ming court and the Chamber of Commerce a headache.

After the Ming army occupied the northern part of Luzon Island, Liu Yu thought about it and negotiated with Su Langqing and other merchants from all over the world, and decided to mint silver dollars to replace silver ingots as the main currency.

This undoubtedly greatly shocked the Ming court officialdom.

The generals of the Ming army, mainly Xiao Wu, were dissuaded.

It's not that these Ming generals dominated by Xiao Wu have any big opinions, and they feel that the abolition of the two Yuan will have an irreversible impact on the future development of the Ming court.

It was because Xiao Wu felt that Liu Yu's hand was too long, and he actually wanted to mint coins.

Therefore, when Liu Yu proposed the coinage, the generals led by Xiao Wu strongly opposed it.

However, Liu Yu insisted on minting coins, and the generals in the court couldn't even do anything about Liu Yu for a while.

After all, in these years, not only must there be soldiers, but also rich and soldiers, which is the real marquis.

Regarding the coinage, King Lu had no choice but to rely on Liu Yu.

It's just that King Lu and Xiao Wu are a little puzzled.

Silver taels are China's currency, and the Ming Dynasty has used silver taels for hundreds of years, so why did Luzon actually abolish the two yuan instead.

If there were corrupt Confucian civil officials in the Ming Court of Luzon at this time, it is estimated that Liu Yu would be drowned by them with foam.

It's a pity that there were no corrupt Confucian civil officials in the Ming court of Luzon, and the generals of the Ming army who were five big and three rough didn't know what the silver system was.

At this time, there was naturally no dispute between the two yuan in later generations, but the large use of Spanish silver yuan and the collision of silver units also gave Ming Court quite a headache.

Based on the experience accumulated over the centuries of large silver coins, Westerners believe that 25~28 grams is a more suitable specification.

Larger silver coins are not easy to make, carry, or use.

In modern times, the large silver coins used by the Western powers are about 25~28 grams, and the small silver coins such as the British shilling, the German mark and the French franc are 5~6 grams.

At the end of the Qing Dynasty, the most popular large silver coins in China were two foreign silver coins weighing about 27 grams, Spain Benyang and Mexico Eagle Ocean, so China's new silver dollar imitated its shape, and the weight of the silver coin was set at nearly 27 grams of Kuping seven coins and two cents, and the settlement was denominated in "yuan", commonly known as "one yuan".

According to the ideas of the Four Seas Chamber of Commerce and the local indigenous officials in Luzon, it is hoped that the Ming silver yuan will follow the Spanish silver dollar and use the seven coins and two cents system, that is, one dollar.

And Liu Yu mainly wanted to mint one or two silver.

"Liang" refers to the weight standard of silver used by the Qing government, "Kuping Liang". In the Treaty of Shimonoseki signed in the 21st year of Guangxu (1895), it was stipulated that each tael of "Kuping Liang" weighed 37.31256 grams, which was generally simplified to 37.3 grams, and there were slight differences in the implementation of various places.

Liu Yu wanted to make one tael of silver, mainly considering that in the future, the Ming army would counterattack the mainland, and the silver dollar would collide with the mainland's two currencies, and the one-tael system would be more suitable for China's national conditions.

However, the merchants of the Four Seas Chamber of Commerce persuaded Liu Yu to advocate the use of a seven-money two-cent system modeled after the Spanish silver dollar.

After thinking about it repeatedly, Liu Yu finally chose seven coins and two cents, that is, the weight of the Spanish silver dollar.

After the first batch of silver dollars was minted, it was presented to the imperial court by Liu Yu.

The front is cast with the four characters of Yongli ingots, and the back is cast with a dragon shape, which is a double dragon playing with pearls.

After such a silver dollar was tried to be made, it was quite popular with merchants from all over the world, after all, such a dragon and Spanish silver dollar did not need to be converted, and after the new silver coin was presented to King Lu, Xiao Wu and others, several people had no objections.

The main reason is that Liu Yu secretly discussed with Xiao Wu that the monthly casting of Long Yang can supply the daily expenses of Xiao Wu's sailors, and at the same time, the newly minted Long Yang was also sent to the generals in the major towns of the Ming Army, and the major generals naturally smiled from ear to ear after getting the new dragon coins.

After all, it's all silver, so is there a difference between the appearance of silver ingots and the appearance of silver rounds?

And these new Longyang sent by Liu Yu to the generals of the Ming army did not take long to be spent by the generals of the Ming army, and the Four Seas Chamber of Commerce agreed to use the new currency to imitate the Spanish silver dollar to a certain extent, and the residents of Luzon did not object, and then the Ming generals spent lavishly and the Four Seas Chamber of Commerce added fuel to the fire, Longyang circulated to the Luzon market in a short period of time, and was recognized by officials and businessmen and civilians.

Of course, the abolition of the two yuan is mainly conducive to the future development of the Ming court in Nanyang, after all, it is to do business with the West.

If you want to use silver dollars to circulate the continent, it is estimated that it will take hundreds of years.

In fact, in the Ming and Qing dynasties, the currency in circulation in the society was actually copper coins rather than silver, and the two-currency system has been used in China's feudal system for thousands of years, and the people used copper coins, coins minted by the government.

Silver and gold are mainly used against copper coins, which correspond to the value of copper coins.

This is also the reason why officials and merchants in the Ming and Qing dynasties always liked to hide silver in their homes instead of taking it out to buy things, because they did not intend to use it to buy things in the first place.

The old men of the blue sky piled up gold and silver at home, and then circulated copper coins in the market, and used silver to determine the value of copper coins.

The minting of silver ingots into silver coins was just a change of appearance, and it did not have much impact on the mainland people in the 17th century, because the currency used by ordinary people for daily biochemical trading was copper coins instead of silver.

Mainly because silver is too expensive, if the official price of one tael of silver is exchanged for two thousand copper coins, then a family of three in ancient times may need to spend more than three taels of silver a year.

Even if the common people suddenly have a few taels of silver in their hands, they will exchange the silver in their hands for copper coins for the convenience of trading.

Therefore, even if the silver is minted into the same coin as the copper coin, it will be slowly shredded in daily transactions because the value of the silver coin is too high, and it is inconvenient for the two parties to change and exchange, commonly known as broken silver.

Therefore, in the Ming and Qing dynasties, silver coins were a purely thankless act, and no matter how good the silver coin ingots you minted, they would be chopped into pieces by the common people for use.

However, at the end of the Qing Dynasty, with the deepening of Western plunder and the opening of trade, thousands of silver dollars flowed into China, and the inflow of silver gradually decreased the price of silver for hundreds of years, which made it possible for silver to be minted into silver coins and used in circulation.

However, in the current Kangxi period, the status of silver is far less cheap than that of later generations to be used as currency in circulation, and changing it to silver dollars has little effect at all.

Liu Yu minted the silver dollar not for the purpose of circulating among the people in the mainland, but for the development of the Luzon Ming court in Nanyang in the future.

In the mainland, the old men of the blue sky can hide the silver at home, and then mint copper coins, and use copper coins to buy things from the common people, and the conversion price of silver and copper coins depends on the emperor's mouth.

When you get to the South Seas, the Spaniards and the English eat your set?

You use copper coins to do business with the Spaniards, and you believe it or not, they will bombard you directly.

Therefore, in Luzon, the Ming court had to mint silver coins in order to develop trade, because the use of silver by Europeans today was as common as copper coins used by the people of the Qing Dynasty.

You can't just rob the Spaniards every day and then buy from the English.

The manufacture of silver dollars can allow the Luzon Ming court to better integrate into the South Seas and even the world, as for the future continent, that is a matter of the future.
