From the barbaric era to the Dutch occupation period, then the Zheng family's pioneering, then the Qing Dynasty's great immigration, the Republic of China, and the Japanese occupation period in the early 20th century, Taiwan's population was in a growth stage.

During this period, the large influx of immigrants concealed the high mortality rate of malaria. In fact, it was not until the Japanese occupation period in the early 20th century that Taiwan had real malaria statistics.

Taiwan is aggressively killing mosquitoes, filling stagnant water, and building underground ditches...

In 1910, Japanese statistics showed that in the past five years, an average of 10,832 Taiwanese indigenous people died every year, while the Japanese died 221 people. This proportion of the population at that time was 3.62 and 3.28 per thousand.

The number may not seem high at first glance, but this is only the mortality rate after illness. There was also a statistic at that time, which was the proportion of Japanese officials who fell ill within 5 years - 907 per 1,000. In other words, in the previous 5 years, almost all

All Japanese officials suffered from malaria. As for the Han people whose living environment was even worse...

Quinine was already available at that time. Without quinine, the survival rate of these officials would be very low, and the people living in the cold zone would die of malaria in large numbers just like the early Europeans in Africa.

In 1941, 70,000 U.S.-Philippine coalition troops surrendered to the Japanese army on the Bataan Peninsula...for no other reason than the outbreak of malaria, the fight was not too serious, and less than a quarter of the soldiers could still hold a gun.

In 1942, all US troops on Guadalcanal were suffering from malaria without exception, and the quinine reserves were quickly exhausted...

This is the most terrifying thing about mosquito malaria: it is highly contagious and can be transmitted repeatedly. There is no immunity and drugs are actually ineffective unless the environment is fundamentally changed.

When it comes to facing malaria, the Taiwanese natives are no better than those dwarfs from Southeast Asia. In fact, everyone is the same. They are all trying to cover up the high mortality rate through muscle shows in the Middle Ages - it seems that they can pull out a lot of people with naked bodies and muscles.

A strong warrior, but behind this is an average lifespan of 30 years, and no one has counted the tribesmen who died of illness in droves like mowing grass.

In the 17th century, the situation was so bad. Taiwan was a barbaric wilderness. There was no mature soil acquired by hundreds of years of immigration through high death rates. There was only the cruelty of fighting mosquitoes every step of the way.

...

To a certain extent, it was the high death rate from malaria work-related injuries that caused some later generations to tear apart the hypocrisy during the peace era, thus giving birth to the slave trade of the Daguan regime.

The basic base of the Chuanchu people is Ming people's immigration. This is the foundation of the regime and cannot be shaken. In fact, they have no choice - from the most basic knowledge of blood, other ethnic groups have been excluded, not to mention beliefs, skin color

, color these obvious things.

Therefore, Chuanchuanzhong now has to establish two population input channels with huge cost differences.

This channel of Mingren is very cheap. The beggars and refugees in Moyunguan can be collected at almost no cost. Even if every Mingren who feeds and sends fat to the officials is burdened with eating meat, clothing, medical treatment and accommodation in Moyunguan

As well as the boat fare, 50 taels of silver per person was a lot.

Akito is cheap, but has a high status: Traveling through the crowd will let Akito go to the kiln area to learn skills and join the army, but he will not send Akito to die. A double critical attack of physical and biological creatures - logging and pioneering.

So who would do the pioneering work with a high death rate? The only option was to buy slaves to do it.

Maritime trade has been the most profitable commercial activity since the Han and Tang Dynasties. The 17th century was the era of the geographical discovery, and the Age of Discovery was in its ascendant. Navigators around the world were walking a tightrope between high mortality and high profits.

In this era, a ship of daily groceries, lacquerware, porcelain, pots and pans, homespun cloth, rouge, sewing needles, etc. could be shipped from the Ming Dynasty. Whether the ship was heading north to Japan or south to the Philippines, as long as it did not encounter

If you go to pirates and storms, then you can get at least 200% profit from the goods on the ship.

This is the characteristic of sea trade. High risks are accompanied by high profits. Otherwise, if they could just set up a stall in front of their home, why would traders of all sizes risk going to sea and risk drowning in storms and pirates?

Let's talk about the slave trade.

The current situation is that the Da Yuan regime neither has the ability to send its own troops to Southeast Asia to capture slaves, but also wants slaves to open up wasteland. Therefore, Chuanchuang has no choice but to buy them from Europeans.

Europeans who were accustomed to the slave trade were naturally not so stupid as to equate slaves with groceries.

First of all, slaves will not run into the cabin by themselves. Whether the colonists start a war or purchase them from the tribe, they still have to pay the cost.

Secondly, slaves are different from pots and pans. Slave ships have a huge and unavoidable risk compared to general cargo ships: from the day they board the ship, slaves will continue to die in the crowded, hot and stuffy cabins where shit and urine flow.

So the slave traders were actually racing against time to reach their destination before all the slaves on the ship and the entire crew including the slave traders died.

This high cost will be spread evenly to every surviving slave. Therefore, without a profit of more than 400%, no one will operate such a risky business. The reason is very simple: no one will take advantage of the slave trade.

If you use the profits from cigarettes to sell cigarettes, the risks are different and the rewards are naturally different.

Travelers buy Nanyang slaves from Europeans, and Europeans have reference prices.

Historically, after the British currency reform in the 17th century, the ratio of pounds to silver was 1:4.3.

The cost for slave traders to obtain a black slave from the west coast of Africa is about 25 pounds {1.07 taels of silver}. After transporting it to the Americas, they can probably obtain items worth about 15.0 {645 taels of silver} pounds, with a profit margin of 6oo%.

By the 18th century, the profits of the black slave trade had further increased. After buying a black slave in Africa for US$500, he could sell it for US$400 in America, with a profit margin as high as 800%.

The above are historical facts, you can find them by just opening Du Niang and searching.

Therefore, in some YY novels of later generations, people can be transported in large numbers from East Asia to the Americas for just two dollars. This is funny. How stupid do Europeans have to be to transport people from more distant East Asia to the Americas?

Years, transporting refugees with a profit of less than 600 taels per person?

In addition, even if the crew members sleep in hammocks, they will still die in large numbers during the voyage. How many of the refugees crowded in the cabins can survive to America? If there are rest stops along the way, there will not be a large number of deaths, probably the slaves

Buy three and get one free already, and humans still don’t know what penicillin does.

...

Therefore, under the above-mentioned price system, the Dutch will definitely not reduce the profit of slaves to the same price as groceries. If the profit is 200%, they can just sell some spices and saltpeter safely. Why trade slaves?

Therefore, the people who traveled through time had no choice but to use more than 300% of the profits to lure the Dutch into slave trading.

Or send your own ship to South Asia to capture people?

...There is no big supply base like the Philippines. A single ship goes out alone, with sparks and lightning all the way, to catch people on tropical islands... This is even more stupid and the cost will be much higher.

It costs 300 silver per person, and then a few lives of time-traveling masters... This is not unusual at all.

Therefore, there is no free lunch in the world. Political correctness is a very expensive way to be correct. If people want to be correct and do not want to bear the reputation of "murdering their ancestors", they must pay a high price now - unless one day
