The development of technology has led to an increase in labor efficiency, which has led to a decrease in all costs.

To sum up, it is not far off that the construction cost of the Huang family's warships and merchant ships will be reduced by half.

This trade trip not only signed friendly trade agreements with many countries, but also the consulate of Daming is about to take root in the prosperous port cities of these countries, and of course, a country branch of "Huaxia Daqian Zhuang" will also come into being.

The area where the Ming Consulate was built was, of course, the purchase of land, which was not large but would become the permanent land of the Ming Dynasty.

If any country dares to treacherously attack the Ming Consulate, just so that the belligerent soldiers of the Huang family can find a reason to invade this country, then it is not the compensation of gold that can solve the problem, and it is the first choice to let such a small country destroy the country and extinct the species.

Due to the world's leading coinage technology of the Huang family, the minted silver and gold coins were favored by merchants from all over the world.

That's because the Xiyi merchants generally used shoddy silver coins made by the Spaniards, and the fineness was uncertain, and even the weight was unreliable.

Originally, the coinage process of the Han people was leading in the world, and the craftsmanship of the Huang family was even more eclectic, standardizing the large-scale production of currency, the same color and weight were equal, and the content of gold and silver coins was more than eighty percent, and this time it was exchanged for a lot of real money and silver by Xiyi.

Of course, the exchange of silver coins and gold coins for gold and silver is full color, and the fineness of the gold and silver used to exchange in Xiyi is insufficient and needs to be folded.

The Daming fleet has talents from the "Huaxia Daqian Village" who professionally inspect gold and silver, and such talents abound in Daming.

Almost every city in the Ming Dynasty has a dumping shop also called a dumping shop, one of the important businesses is to exchange broken silver for silver ingots, if they can't identify the fineness of gold and silver, wouldn't they want to lose their wives?

However, the business of dumping silver shops does not exist in the Huang family system, because the people of the Huang family all use Huaxia Tongbao gold, silver, and copper coins, and no one is stupid to use clippers to cut silver ingots into small pieces and weigh silver to buy things.

The common people exchange gold and silver for Huaxia Tongbao and go directly to the "Huaxia Daqian Village", which has a special master of the silver shop to train qualified professionals to serve the people.

Now the common people of the Huang family system no longer secretly hide gold and silver at home, they are willing to use gold and silver coins, and they are all assured to boldly deposit their savings in the "Huaxia Big Money Village" to earn interest.

The Huang family of course welcomes it, and the need to exchange gold and silver coins will definitely meet their needs, and the gold and silver brought back will be produced in large quantities into gold and silver coins and sold to them next time.

In the near future, the number of Xiyi using Huaxia Tongbao will multiply.

At that time, there would be many "big Chinese money villages" in Xiyi countries, and there was no doubt that there would be countless Xiyi who handled remote access.

They deposited the wealth they plundered in South America and Africa into the "Huaxia Big Money Bank," and as long as they paid 3 to 9 percent of the fee according to the distance they traveled, they could withdraw cash from the "China Big Money Bank" in their own country in Europe.

Historically, too many Spanish treasure ships carrying precious metals have been attacked at sea, sunk in the Atlantic, or have been captured by the attackers.

It's not just pirates who do this, but also the navies of other countries.

The sea is not very peaceful, and the accumulation of half a lifetime of colonists may come to naught, and with the off-site storage of "Huaxia Big Money", these riches will no longer be used as wedding dresses for others.

The risk of running the sea is all borne by the Daming fleet, in fact, the transfer of cash at sea does not need to be carried out all the time, and it can be scientifically allocated according to the cash flow of the major banks.

When transporting gold and silver coins on a large scale, it is enough to take heavy military escorts, and reasonable deployment will make the cost controllable, and the income of the water will make the "Huaxia Big Money Bank" very happy.

With the protection of the terror of the Ming Dynasty, the moment of financial globalization is coming, and the day when the "Huaxia Big Money Village" will really connect the world will not be too long.

The scholars who followed the sea were very busy, there were too many things, it was self-evident to cultivate cinchona trees and rubber trees, and the improvement of the navigation atlas must also be done as soon as possible, and the Huang family's globe upgrade was underway, and too many inaccuracies would be modified.

The fleet of "China Development" will also make a trip to Europe this year, and the plan for the first month of next year is a trip around the world.

Huang Mingdao is about to lead the fleet from the Old Port, through the Cape of Good Hope through the Strait of Magellan to find the Hawaiian Islands, and occupy this place as a foothold, and then cross the Pacific Ocean to Iwo Jima and return to "Huaxia Island".

Huang Sheng set up a celebration banquet to invite all the scholars who returned from the voyage, and it happened that Xu Youkuan, the chief housekeeper of Wei Guogong, came to "Nanhua Island" again, and Xu Hongzu arranged family affairs and came with Xu Youkuan.

Xu Youkuan once again introduced several talents, and every time he came to "Nanhua Island" to send talents, he was courteous and received many rewards.

He is full of energy, happy to return to the prince, after returning to Nanzhili, he must send more small people to inquire about the people, there are talents missing.

Among the talents of Nanzhili who came this time, there was another Huang Sheng who had heard of it in later generations.

This person's name is Fang Yizhi, a famous thinker, philosopher, and scientist in the late Ming Dynasty, in fact, Huang Sheng doesn't know this, only knows that Fang Yizhi is one of the four sons in the late Ming Dynasty.

Of course, at the end of the Ming Dynasty, the fourth prince broke a vat of sauce due to the defection of Hou Sui's son Hou Fangyu.

Fang Yizhi is not a soft egg, he is a good man, when the Qing army marched south, he contacted the southeast anti-Qing forces to fight to the death, and later the men and horses were defeated by the Qing army, Fang Yizhi still turned to fight.

In the end, the Qing soldiers captured Pingle, Guangxi, Fang Yizhi was arrested, he was loyal and unyielding, and the Qing generals were moved by his justice and allowed him to become a monk. After his release, he refused to go out, changed his name to become a monk, changed his name to Hongzhi, and ended up in the whole festival.

Huang Sheng and Fang Yizhi talked about philosophy, medicine, and physics, which made him pause.

Wu Youxing and Fang Yizhi have been familiar with each other before, and at this time, they belong to a foreign country and meet old acquaintances, of course, they must not get drunk.

He frequently clinked glasses with Fang Yizhi, and during the banquet, Wu Youxing, who was not without pride, told his old friend that the Huang Family Medical College had developed a good medicine that could cure malaria.

A cure for malaria? Fang Yizhi was attracted, he listened to Wu Youxing and Hu Jianya vaguely told that there are too many overseas species, and their research time is too short, and they may not be able to study one in ten thousand, and the stones of other mountains can attack jade.

If it weren't for species from far away, it would have been impossible to develop such a life-saving medicine.

In the Ming Dynasty, there was really no special medicine for the treatment of malaria, the effect of Artemisia annua, Li Shizhen's "Compendium of Materia Medica" was clearly written, bitter, cold, and non-toxic. It is mainly used for children's wind chill and fever.

Artemisia annua, also known as Artemisia stink, had the technology to extract artemisinin in later generations, and it became the first choice for malaria prevention and control in the world in the late eighties.
