Researching and building hydraulic machine tools is not something that Wang Dazhui can do alone, Wang Dazhui took a few craftsmen and Tang Bei's group to converge.

Before Wang Dazhui led people to build manpower machine tools, grenades, and tiger head guns, Tang Bei took a group of people to study hydraulic machine tools first, and even went to the outside world to see the water wheel.

The waterwheel and the hydraulic machine tool are still very related, and the study of the waterwheel is of great help to the study and construction of the hydraulic machine tool.

Tang Bei was a little surprised, when he was studying the waterwheel, Tang Bei found a lot of hydraulic equipment, the water mill for rice cooking, the water mill for grinding noodles, and of course, the most common is the waterwheel used for irrigation.

The waterwheel is to transport water, but the water mill and water mill are driven by flowing water to drive the movement of equipment to process food, which is very labor-saving.

From Tang Bei, who lives in the mountains, has not been in contact with hydraulic equipment before, and now he sees these hydraulic equipment, and soon understands the role and principle of hydraulic machine tools.

Understanding the role and principle of hydraulic machine tools, Tang Bei's research progress on hydraulic machine tools was greatly accelerated, and even tried to make models out of wood.

Wang Da Hammer pulled out, with a few craftsmen and Tang Bei together, Wang Da Hammer after seeing several hydraulic equipment, but also suddenly realized, water to drive machine tools, than manpower is much less trouble.

However, there is also a big disadvantage compared with the hydraulic machine tool and the manpower machine tool, that is, the whole structure of the hydraulic machine tool will be very large together, much larger than the manpower machine tool, and it will take more time to build a hydraulic machine tool than to build a manpower machine tool with the same function.

But with the work of hydraulic machine tools, it is worth building, and in the next period of time, Wang Dazhui, Tang Bei and others will be stationed by the river, thinking about building the first hydraulic machine tool as soon as possible.

……

As the People's Army occupied most of Guangdong, it was inevitable to come into contact with foreigners.

For example, the Portuguese, this year is the fourteenth year of Wanli, and it is also 1586 AD, in 1553, the Portuguese obtained the right of residence in Haojing, and so on next year, the Portuguese will officially occupy Haojing through the procedures of diplomatic documents.

In this regard, Fang Nan only has one sentence: "The territory of China cannot be missing at all." ”

In Guangdong, in addition to the Portuguese, there are also people from other Western countries, mainly maritime merchants, who come to Daming to carry out business and trade activities, and bring a shipload of Western countries' specialties to the Ming Dynasty, and a shipload of tea, porcelain, etc. back to Western countries, can earn more than ten times the principal.

Although there are all kinds of dangers on the sea, I don't know how many people have set foot on this road for the sake of wealth.

The KPA has come into contact with foreigners, and the KPA needs a way of dealing with foreign countries, whether to be friendly, hostile, or ignore.

Fang Nan had seriously thought about this question.

If the People's Army is friendly with foreigners, it means that the People's Army needs help from foreigners, but where does the People's Army need help from foreigners?

Fang Nan thought about it carefully, and didn't think of a place where there was a need.

The firearms of Western countries developed rapidly, and the most advanced artillery of this era, the Franc machine gun, was the first to be taken out by Western countries, and the guns of Western countries were also more powerful than those of the Ming army.

But the People's Army has more powerful firearms, and the Tiger Head Gun can be called one of the most powerful muskets before the arrival of the breech gun era, but due to the limitations of technology, the Tiger Head Gun still has room for improvement.

The Francophone cannon used by the People's Army, Foshan can be cast in large quantities, grenades, and only the People's Army can cherry

The KPA does not need firearms from Western countries, and Western countries are so far away that it will take more than half a year for firearms to be shipped back.

Friendship with foreigners to trade and obtain large quantities of gold and silver?

Needless to say, gold and silver are precious metals and are used as trading currency, and paper money can be used as long as the credit is sufficient.

For a merchant, obtaining a large amount of gold and silver represents a rapid increase in personal wealth, but for a country, the inflow of large amounts of gold and silver is not necessarily a good thing, and in the absence of much change in output, a large inflow of gold and silver will only cause the value of gold and silver to depreciate, unless it can be quickly traded with another country to buy various outputs from this country.

Obviously, the current People's Army will not even be needed when it may overthrow the Ming Dynasty and establish a country in the future.

After careful consideration, Fang Nan understood that the KPA did not need to be friendly with foreigners, and the KPA could not get much useful from foreigners.

The fact that there is no need to make good friends does not mean that the People's Army will have to fight against foreign countries, at least now the People's Army cannot fight against foreign countries, the Ming Court is the great enemy of the People's Army, and the People's Army does not want to have a few more enemies.

Therefore, when dealing with foreigners under the rule of the People's Army, Fang Nan only requires foreigners to abide by the laws and regulations of the People's Army, and foreigners who violate the law will be punished, and foreigners who abide by the laws and regulations can conduct normal business and trade activities.

As for the Portuguese to occupy Ho Kyong, the People's Army will not allow it anyway.

Before Haojing was owned by the Ming court, the Portuguese only had the right of residence in Haojing, but now Haojing is controlled by the People's Army, and the grape people still only have the right of residence.

The Portuguese were very alarmed by the appearance of the People's Army, some of them fled directly to the sea by boat, and some of them did not have time to escape.

What the Portuguese do, as long as there are no violations, the KPA will not care, even if they all leave, it doesn't matter, but the Portuguese returned to Haojing after seeing that the KPA did not do anything to them, and even the Portuguese took the initiative to contact the KPA, wanting to ask what happened, but the KPA did not pay attention to the Portuguese.

After a few years, the Portuguese in Haojing learned a little about the People's Army, and only then did they understand that the People's Army and the Ming Dynasty were enemies.

Some Portuguese secretly laughed at the People's Army, they knew that the Ming Dynasty had a vast territory and a large population, and its strength was more than ten times stronger than that of Portugal, and they did not think that the People's Army could defeat the Ming Dynasty, and soon the Ming Dynasty would exterminate the People's Army.

However, there are also Portuguese who see this as an opportunity to perhaps gain some benefits from the People's Army.

For the Portuguese, who took the initiative to contact, the KPA still ignored it.

Although the People's Army only occupied most of Guangdong and was far less powerful than the Ming Court, Fang Nan occasionally diverged his thinking and thought about the scene after the People's Army overthrew the Ming Dynasty.

Compared with the whole earth, the territory of the Ming Dynasty is still too much, once a large area is affected by disasters, turmoil ensues, and the fall of the Ming Dynasty has the reason of the Ice Age.

If the territory of a country is large enough, or even the entire earth is a country, then a disaster occurs in one area of the earth, but other regions are not affected, and one side is in difficulty and all sides are supportive, in this case, even if a relatively serious disaster occurs, the impact on the country will not be too great.

Such an idea was pressed in Fang Nan's heart, and even the Ming Dynasty was not overthrown, thinking about these things was useless.
