In the 17th century, the Netherlands attacked everywhere like Spain in the 16th century, robbing Spain's original colonies everywhere, which made Spain, which had always been a great power, lose face, and a war of independence even directly dragged down Spain's economy.

Although a steady stream of gold and treasures plundered from the Americas supplemented the country's economic expenditures, Spain's domestic inflation rate increased because of the nationwide enjoyment of the full name.

The wealth brought by plunder brought the Spanish people into the Age of Discovery, and at the same time, the Spanish people did not produce, and the country's various industries entered the regression.

The wealthy Spaniards began to buy everything with the plundered money, and this consequence directly planted a time bomb for the fall of Spain.

Whether Spain recognized it or not, the Dutch had risen to become a maritime power that could not be defeated by the Spanish navy alone.

However, the dream of the Spring and Autumn Festival of a great power has always been rooted in the hearts of every Spaniard, and the money brought back by overseas colonization has made Spain, a country that is partial to the Iberian Peninsula, completely qualified to participate in the affairs of the European continent, and even become the most powerful hegemon on the European continent.

The Spanish phalanx was even more powerful in the second half of the 16th century, and this unprecedented pride of great power was deeply rooted in the hearts of almost every Spanish citizen, and even if they could not accept many of the king's decisions, they must not allow this glory to be replaced.

This is why the Spaniards fought the war of independence for 80 years in order to suppress the Dutch, but they were able to fight it all the time, and there was no large-scale anti-war sentiment among the people at home.

But with the passage of time, the once great power has come to a waning mountain, but it is just empty of the halo left by its ancestors.

The Spaniards, who had sensed that something was wrong, at least not so arrogant as to think that they were still the king who could defeat all opponents, began to seek mutations, to find new ways to solve their defeat on the battlefield.

Finally, the appearance of the Australians gave them hope, a mysterious and oriental country, their weapons are sharp, their artillery fire is lighter and farther than any country on the continent, and the accuracy rate is quite high.

Although the Spaniards were arrogant and had the feelings of a great king, they were not stupid and did not averse to accepting new affairs, and when they saw the tremendous energy of the new Australian weapons in the battlefield, they began to move, and even began to act.

They must get such weapons, they must be, if the Spanish army is equipped with such advanced and sharp weapons, the battlefield will be invincible, whether it is the Gauls or the Dutch old to hell, the mighty Spain will once again become the hegemon.

In order to defeat the Dutch and even the anti-Habsburg coalition, he continued to expand his army, bringing the number of regular Spanish armies to 300,000.

In the face of such huge military spending, coupled with the economic crisis in the country in recent years, the once rich Spain is really unable to support it, so whether it is facing the Dutch war of independence or the war against the Habsburgs, it must be ended as soon as possible, so that Spain can fight against the Dutch at sea.

Although the declining empire was temporarily mired in an economic crisis, the colonies he nominally controlled were still the largest, whether it was the rising Netherlands or the Portuguese Empire, which once rivaled Spain and colonized the world, it was only one of its provinces.

The total value of the arms orders brought by Carlos is more than one million Spanish silver dollars, of course, they do not have enough money to pay at the moment, but the lack of money is not important to Australia, on the contrary, a large amount of silver is not a good thing for Australia.

Just like Spain, he accumulated great wealth by plundering and eventually became a worldwide colonial empire, but because of the sequelae of plunder, he went into decline.

What Australia needs is a variety of material species, which are then processed into various finished products for export, and Spain can provide just that, such as the famous merino sheep, basically all the fine wool in the world is produced from it.

However, in 17th-century Spain, exports were absolutely forbidden, and each export of a sheep was almost equivalent to a capital offense, which brought great profits to the loss of Merino sheep.

At present, Australia has more than 20 merino poplars, but it is still far from becoming an industry for large-scale breeding, so it is not a way to introduce formal channels like Spain.

The exchange of benefits brought by Carlos is to lease a piece of coastal land in Luzon to Australia, and even sell it directly to Australia as a mortgage for the purchase of arms, but Australia is not so strong about the need for such a piece of land**.

In addition, the concession area of Hong Kong is under construction, and it is not suitable to continue to develop a second site at this time, so the import of merino sheep and natural rubber from South America has become the first choice in Australia.

Yu Bowen's condition is that Spain will export more than 200 merino sheep in batches like Australia, as well as American natural rubber and potatoes produced there, but this species may have been introduced to the Ming Dynasty, but it has not been cultivated on a large scale.

In the face of the conditions proposed by Bowen, Carlos has almost no authority to reply, except for merino sheep, other species, basically can agree, but merino sheep are strictly prohibited from being exported by Spain, which requires His Majesty the king to make a personal decision.

So Carlos agreed to help the Australians collect the elastic sap in South America, that is, the items they became rubber, in Carlos's opinion, it is not difficult to collect the latter few things, and the Australians did not take them for free but as collateral for arms, although the price of these items is not very high, but at least one of the items that Australia is interested in.

It wasn't until more than a hundred years later, when scientists in the Western world discovered the true use of rubber, that Carlos's descendants felt as if their ancestors had been deceived by the shrewd Aussie.

However, at this time, the Australians, who have fully mastered the multiple uses and patents of rubber, have been at the forefront of the world in this industry, no matter how the Western world opposes and clamored to increase the export price of rubber, and even the severe rubber sanctions plan for Australia, in the end it has just become a bubble, because they have not mastered the technology of rubber products at all, and even the sanctions will only put their domestic dependence on rubber exports to the people in trouble, and finally this kind of sanctions can only be stopped.
