With the progress of trade, the silver dollar of the Ming Dynasty also began to gradually enter Europe, and the beautifully forged and serrated silver dollar of the Ming Dynasty was warmly welcomed by the merchants.

At the same time, there are also gold coins of the Ming Dynasty that entered Europe, and the gold coins are also half double, and one yuan gold coin is equivalent to ten yuan of silver. Gold coins are even more popular than silver coins, because gold coins are obviously much more convenient than silver coins for large transactions. The king of Poland agreed with Wang Zheng that the loan of the Ming Dynasty would be paid in the form of half gold coins and half silver coins. And Wang Zheng directly took out 100,000 gold coins and handed them over to Poland as the first installment of the loan.

Wang Zheng brought a total of 100,000 yuan in silver coins and 100,000 yuan in gold coins. The mission was on the largest ship of fortune, and there was no need to worry about someone playing the role of pirates along the way. This Daming fortune ship will cause a sensation every time it arrives, compared with European ships, the Daming seems a little stupid, the speed will be slightly slower, and it is not very convenient to get on and off the ship. But it's big, it's steady, it's fierce. When passing through the northwest corner of Africa, two warships without flags were embellished with it, but the mast was set on fire by a few cannons of the Daming, and the Ming army killed the people on both ships, and then moved the things on the ship and set fire to the ship. Of course, the incident of these two warships belonging to the Spaniards was remembered by the Ming army, waiting for the report to be reported after returning home, and it was up to the emperor to decide how to deal with it.

After Poland, there is only one country: Sweden. Sweden is a Nordic powerhouse, and a few years ago, after the death of Sweden's most famous king, Gustav II Adolf, known as the Lion King, his daughter Queen Christina succeeded to the throne and became known as the Girl King. At this time, the actual control of Sweden was in the hands of Swedish Prime Minister Axel Uksensena.

The lion king saw himself as the protector of Protestantism, and fought wars with Poland, the Rakshasas, and the German states. Protestant doctrine asserts that everyone can speak directly to God without the need for intermediaries, i.e., the presence of the clergy is no longer necessary. Zhu Youxiao liked the teachings of Protestantism very much, so in his letter, he first expressed his support for Protestantism, which was immediately favored by Swedish Prime Minister Axel Üxenachena.

And when Zhu Youxiao then asked for an alliance with Sweden to jointly deal with the Rakshasa Kingdom, Axel Uxsensena agreed without hesitation. He also understands the truth of distant and close attacks, if Da Ming attacks from the other side of the Rakshasa country, then the Rakshasa power he has to face will be greatly reduced, and Sweden does not need to pay anything, such a good thing only a fool will not agree.

Wang Zheng left ten students and asked them to be arranged for internship in the Swedish artillery unit to learn the advanced technology of the Swedish artillery, and the Swedes also got permission. The Swedish artillery was the strongest artillery in Europe at that time, not to mention the power of the artillery, but only the quality of the artillery and the perfect discipline, all of which have merit.

It took more than half a year for Wang Zheng's trip to Europe to come to a successful end. The Ming Dynasty first communicated with the Holy See and won the independence and autonomy of the Catholic Church in the Ming Dynasty. It has formed friendly relations with European powers, and has formed alliances with Poland and Sweden, which are hostile to the Rakshasa State.

More importantly, the accompanying Jinyi Wei and the students collected information on the terrain, products, customs, and other aspects along the way, which will become very important information, and will become a guide for future research on Europe and dealings with European countries. Of course, they bought the bookboxes and even magazines that they could see along the way, and those that could be translated were translated now, and those that could not be translated would be handed over to the Translation Bureau after returning to China, and then handed over to the research institute for research.

According to the plan, the mission also had an important mission, which was to travel from the Atlantic Ocean to the Americas, then from the southern tip of the Americas back to the South Seas, and back to the country, for a round-the-world trip. Not only did Zhu Youxiao want to deeply root the idea that the earth is round, but they also wanted to visit the Ming soldiers in the Americas, comfort the Yin Di'an compatriots, and strengthen the ties between the two places.

Although there were enough nautical charts, it took a long time for the mission to arrive at Huaxia City, the largest base of the Ming army in the Americas.

Zhou Yanru, Hu Qinzhai, Geng Zhongming and others happened to be in Huaxia City, discussing how to attack the Spaniards from Huaxia City. Now there are 13,000 Ming troops in the Americas, and more than 105,000 Ming immigrants. And the Yin family is as high as more than 500,000 people. From Hongwu City in the southmost to Wanli City in the north, the distance can reach more than 8,000 miles.

In such a large place, even if it is only a coastal area, the number of people is too small, except for some cities, it is not easy to see people in other places. Fortunately, there is plenty of food in these places, the climate is suitable, and after the domestic immigrants meet the needs of the north, there will be a large number of immigrants coming here, and then it will be very lively, according to Zhou Yanru's estimates, according to Chen Houfu's news from the Immigration Guidance Bureau, two years later, the number of immigrants in the Ming Dynasty will exceed the Yin family, reaching about one million.

Wang Zheng had a holy decree, and the Ming Dynasty decided to crown Sange as the chief of the Yin family, ruling over all the Yin families on the west coast of the Americas, and the other leaders of the Yin family were also named leaders, each governing the Yin family in a place. This is the Ming Dynasty for the future immigration work, after more immigrants, there may be some conflicts of interest with the Yin family, now the Yin family is divided into a place and a place, which is convenient for future management.

And the emperor instructed Wang Zheng to take a good look at Panama, and let people draw a map of the vicinity, investigate the geographical and geological conditions, of course, the most important thing is to occupy this place, it is completely occupied, except for the Ming people and the Yin family, no one else can live in this place.

According to the sketch drawn by His Majesty the Emperor, the Ming army found this place called Panama, where a group of Spaniards had been stationed, but the number was small, and after being defeated by the Ming army, it was only through interrogation that the Spaniards were also here to investigate and prepare to dig the canal. As a result, the information explored by the Spaniards became the information of the Ming army, and the Ming army also built a city on the Atlantic side of Panama, which was named Yongle City in the order in which the emperor named it.

The geography students brought by Wang Zheng carefully investigated the situation in this area, drew a relatively accurate map, and believed that there were no basic conditions for digging a canal here. Because this is a large tropical rainforest, humid and hot, dense jungle, traffic congestion, and complex terrain, if you want to dig a canal, you must first change the infrastructure here, which is obviously not something that can be done in a short time. Let's talk about immigration, there is a lot of land on the west coast of the Americas, who would want to live in this place full of poisonous insects and hot climate? Except for the places near the sea on both sides, the place in the middle of more than 100 miles is not suitable for human habitation at all.

However, this has nothing to do with Wang Zheng, and the emperor is not going to dig a canal now, but this place must be occupied. Because Yongle City is close to the sea, the Spaniards may attack at any time, so Hu Qinzhai stationed 3,000 soldiers here, placed a large number of artillery, and Geng Zhongming personally guarded here.
