How did the plague, or contagion, that caused human beings to be so dead all over the field, come about in the first place?

Is the source of infectious diseases spontaneous or foreign?

Based on modern scientific research, human beings have come up with the answer that the original source of infectious diseases is mainly foreign, and most of them are obtained from animals.

Historically, a considerable number of diseases that endanger human life, especially almost all virulent infectious diseases, have been transmitted from animals. Near-range ones such as mad cow disease and avian influenza, distant ones such as smallpox, measles, and yellow fever...... They are all after the birth of human civilization, with the rise of animal husbandry at the same time of civilization companions - many animals were originally harmless or harmless microorganisms, in the day and night get along with each other into the human body, because it is a complete alien species, often in the human body adverse reactions, causing human diseases, this is the plague.

Among the mammals raised by the ancients, such as cats, pigs, sheep, horses, cows, etc., there are similar pathogens between humans, and pathogens and viruses can easily interbreed and mutate to form new pathogens. Human beings in Europe, Asia and Africa have been living in this dirty microscopic environment for thousands of years, suffering from diseases, and at the same time, their own bodies are constantly adjusting, and gradually have the ability to resist sudden and virulent infectious diseases, thus ensuring the continuation of the race.

The Indians of Mexico have only one type of domestic animal, the dog. However, there is the least amount of disease crossover between dogs and humans.

Therefore, the Indians of the New World have always lived in a kind of microscopic environment that can be said to be very clean, like a sterile room in a hospital (otherwise according to the terrible custom of the Mayans and Aztecs who liked to pile up thousands of rotting corpses in the city for sacrifice to the gods, they would have died of plague in the Old World), so they lacked the corresponding immunity. Once exposed to the virulent infectious diseases of the Old World, there were mass deaths - there was once an isolated Indian tribe in the United States who went from 2,000 to only 40 in a matter of weeks after their first exposure to smallpox!

European germs of the same era can still cause at least 80% of the population of the Indians, let alone modern germs that have been tested by various antibiotics in the 21st century and have increased their pathogenic ability many times?

Obviously, compared with the travelers who pay attention to personal hygiene, the various animals obtained from later generations are definitely more terrible germ hosts. Although the travelers have vaccines and antibiotics in their hands, the germs will probably spread faster than the drugs can be sold - and when the American continent is a no-man's land infested with diseases, who will they do business with, and who will cut wood and dig for gold?

Therefore, for the time being, Mr. Wen's women's army can only use electric tricycles to practice cavalry tactics......

――――――――――――――――――――――

In general, the Indian civilization of Central America is a seriously lame civilization, and there are so many shortcomings in all aspects that it makes people dizzy.

Even in the most basic aspects of agriculture, there are many staggering gaps and shortcomings.

As we all know, the high-yielding crops introduced to China from the Americas are most famous for potatoes and corn. These two high-yield grains were introduced to China in the Ming and Qing dynasties, especially in the strong period before the Qing Dynasty, and made outstanding contributions to the explosive growth of the Chinese population.

However, after Wang Qiu and his team traveled through time and space, they found that the main varieties of crops here were corn, pumpkins and beans as food, sweet potatoes, tomatoes and peppers as vegetable snacks, tobacco and cocoa beans as pastimes, but there were no famous potatoes!

What's going on? The Indians of Central America did not even have potatoes?

Later, they carefully checked the information and found that the corn was indeed native to Central America and was the result of painstaking cultivation by the Mayans. Potatoes, on the other hand, are native to Peru in South America and were the main food crop of the Inca Empire. Between the two origins, there is a distance of about 1,000 kilometers. After thousands of years, corn finally spread from Central America to Peru, while potatoes did not spread from Peru to Central .........America.

As a result, it was clear that in the Americas, the origin of potatoes, they had to get potato varieties from modern times and teach indigenous people how to cultivate and eat them.

In fact, in the American continent at this time, just knowing how to dig irrigation canals to grow crops was already an excellent nation with very high-end advanced productive forces. Many of the tribes that are a little backward do not even know how to farm.

For example, the Chichimec people who lived in the desert of northern Mexico in this time and space were defined as nomads in later history textbooks, which is also very consistent with the historical view of the Chinese - the south is the farmers who built cities and settled, and the north is naturally the nomadic people who live in no fixed place.

Then, after traveling to this time and space and seeing some Chichimec people with his own eyes, Wang Qiu was stunned to find that saying that they were nomads was purely to put gold on their faces! It's almost the same as saying that it's a blind beggar gang!

-- Cows, sheep, and horses, which are the standard equipment of the nomads of Eurasia, are none of the Chichimec people who roam northern Mexico, nor are the alpacas, the mythical beasts of the Incas in the south. The only animals they know how to raise are dogs. But no matter how much they are domesticated and crossbred in, I am afraid that dogs will not be able to replace horses for people to ride, or grow fatter than cattle and sheep.

So, with the exception of a few advanced elements who learned to grow corn, the Chichimeks, who did not know much about farming, survived only by hunting, fishing, and gathering wild fruits. However, their numbers were too large to survive by fishing and hunting, so they had to continue to go south to rob various agricultural tribes and city-states. If you win the battle, you will feast on a few meals of corn and pumpkins that you have stolen; If you lose the battle, you just wait to starve to death or become a slave, but you can't do it, and you can still eat the flesh of the dead......

However, in the slave markets of the civilized city-states of Central America, the Chichimeks were the least popular "goods". Because they often have no concept of farming at all, let alone ask them to do farm work, it takes a lot of effort just to figure out what farmland is.

Getting back to business, seeing that it seemed that there was no way to reduce the spending on armaments, Wen Desi and Wang Qiu began to think about where to increase their revenues.

In the past period of time and space trade, Wang Qiu's profits were mainly sourced from two major quantities: the first was gold, silver and natural gemstones, and the second was timber. In addition, there are some handicrafts, beautiful shells and other bits and knick-knacks.

First of all, after two years of inter-temporal commodity trade in Mexican in 16th century Central America, the time-travelers came up with nearly a ton of gold and three and a half tons of silver...... Combined with all kinds of natural gemstones, and then subjected to a layer of exploitation by bank buyers, the total income was about 700 million yuan - but this was not pure profit, and in order to obtain this money, Wang Qiu and his family had to purchase astronomical quantities of modern industrial goods, selling millions of boxes of matches alone, as well as tons and tons of salt and sugar, and thousands of steel knives and glass ceramics...... In addition, the infrastructure construction of Hope Port (cement, color steel mobile housing) also costs a lot of money, and it has to be squeezed out of this money.

In addition, another major source of income in Mexico is, of course, timber - unlike the relatively scarce gold, silver and gemstones, in the undeveloped rainforest, the resources of timber are truly inexhaustible, and no one considers it of value at all.

Through the hard work of tens of thousands of Indian loggers throughout the year, although they have no humming chainsaws or large trailers with black smoke, they can only be cut and dragged by manpower, but after all, there are many people, and at least hundreds of logs are transported to the main square of Hope Port every day. …,

Due to the huge difference of 1 to 24 in the flow rate of time between the two sides, one day in modern time and space is equivalent to 24 days in Mexico, and as a result, since the beginning of August, Wang Qiu has to get more than a dozen or even dozens of containers of timber to the dock almost every day, and then ask Ma Tong to call Zhou Mifan's boss to come and receive the goods - however, such a huge amount of timber is taken out at once in such a short period of time, how can a mere medium-strength timber merchant eat it all?

In fact, when he received the fourth batch of "Mexican smuggled timber", the boss Zhou Mifan was already stunned by so much timber that he could no longer eat more goods - although these timbers were super bargains like pie in the sky, because Wang Qiu and Professor Yang did not accept the deferred payment, they had to immediately trade in cash, and as a result, although Boss Zhou had tried his best, and even went to borrow a loan shark, he could not raise tens of millions of working capital in just three days.

There is no way, if you want to find a buyer for such a large amount of wood, at the level of Boss Zhou, it will never be possible without ten days and half a month.

Fortunately, this Boss Zhou has been up and down in society for many years, and he still has some connections. Seeing that the government leaders were in a hurry, they volunteered to act as an intermediary and found many other large and medium-sized timber merchants to peddle, so that they could make a fortune together. In this way, he not only fulfilled the requirements of the government personnel, but also earned some referral fees from them, or made the other party owe a favor...... As a result, in late August, there were procurement personnel from as far away as Henan and Hubei who came to see the goods. As a contact, Ma Tong even had his mobile phone blown up several times.

At present, in order to deal with the successive timber buyers, Ma Tong, who has not yet recovered from dysentery and dehydration, has to stay on the side of the wormhole to answer the phone, and has no time to travel to the beach in Mexico to bask in the sun and harass the Indian cute girl by the way.

And our Cai Rong group leader ...... Well, Lori's immunity is generally poor, and she is still on the injection, and her fever has not completely subsided.
