How did the plague, or infectious disease, that caused human corpses to spread across the wild in the first place?

Is the source of infectious diseases spontaneous or external?

The answer that humans have come to based on modern scientific research is that the original source of infectious diseases is mainly foreign, and most of them are derived from animals.

In history, quite a number of diseases that endanger human life, especially almost all severe infectious diseases, were transmitted from animals.The near ones are mad cow disease and bird flu, and the distant ones are smallpox, measles, and yellow fever...they are all companions of civilization after the birth of human civilization and the simultaneous rise of animal husbandry—many animals were originally harmless or not very harmful Microorganisms that enter the human body during the day and night together, because they are outright heterogeneous, often cause adverse reactions in the human body and cause human diseases, this is the plague.

Among the mammals raised by the ancients, such as cats, pigs, sheep, horses, cattle, etc., have similar pathogens with humans. Germs and viruses can easily hybridize and mutate, forming new pathogens.Human beings in the three continents of Europe, Asia and Africa have been living in this dirty micro-environment for thousands of years, suffering from diseases. At the same time, their bodies are constantly adjusting, and they have gradually acquired the ability to resist sudden severe infectious diseases, thus ensuring the continuation of the race.

The Indians in Mexico have only one domestic animal, the dog.Dogs and humans have the least amount of disease crossover.

Therefore, the Indians in the New World have always lived in a microscopic environment that can be said to be very clean, just like a sterile room in a hospital (otherwise, according to the Mayans and Aztecs who like to stack thousands of Carrion, a terrible custom used to sacrifice gods, should have been wiped out by plague in the Old World long ago), so they lack the corresponding immunity.Once exposed to the violent infectious diseases of the Old World, they will die in large numbers-there was once an isolated Indian tribe in the United States. After the first contact with smallpox, only a few weeks after the first exposure to smallpox, only 2000 people died from 40 people!

European germs in the same era can still destroy at least 80% of the Indian population, let alone modern germs that have withstood the test of various antibiotics in the 21st century and have increased their disease-causing ability by an unknown number of times?

Obviously, compared with the traveler who pays attention to personal hygiene, all kinds of livestock brought from later generations are definitely more terrible hosts of germs.Although the traversers have vaccines and antibiotics in their hands, the spread of germs will probably be faster than the sales of medicines. At that time, the American continent will become a deserted wilderness full of diseases. Who should they do business with? Who will chop wood and mine gold?

Therefore, for the time being, Mrs. Wen’s Women’s Army can only use electric tricycles to practice cavalry tactics...

In general, the Indian civilization in Central America is a severely lame civilization, with so many technical shortcomings in all aspects that make people dizzy.

Even in the most basic aspect of agriculture, there are many overwhelming gaps and flaws.

As we all know, potatoes and corn are the most famous high-yielding crops introduced to China from the Americas.After these two high-yielding grains were introduced to China in the Ming and Qing Dynasties, especially during the strong period in the early Qing Dynasty, they made outstanding contributions to the explosive growth of China's population.

However, after Wang Qiu and the others traveled through time and space, they found that the crops here mainly include corn, pumpkin and beans as food, sweet potatoes, tomatoes and peppers as vegetable snacks, and tobacco and cocoa beans as recreation. The famous potatoes!

What the hell does this happen?The Indians of Central America didn't even have potatoes?

Later, they checked the information carefully and found that corn was indeed native to Central America and was the result of the hard work of the Mayans.Potatoes originated in Peru in South America and were the main food crop of the Inca Empire.Between the two places of origin, there is a distance of about 1000 kilometers.After thousands of years passed, maize finally spread from Mesoamerica to Peru, but potatoes did not spread from Peru to Mesoamerica...

As a result, they had to acquire improved varieties of potatoes from modern times to teach the indigenous people how to cultivate and eat them, even though they were in the Americas, the origin of potatoes.

In fact, in the American continent in this era, just knowing how to dig irrigation canals and grow crops is already an excellent nation with high-end advanced productivity.Many tribes that are a little behind simply don't even know how to farm.

For example, the Chichimeks who lived in the deserts of northern Mexico in this time and space are defined as nomadic people in later history textbooks, and this is also in line with the Chinese historical point of view—farmers who built cities and settled in the south, and natural people in the north. They are nomadic nomads.

Then, after traveling to this time and space and seeing some Chichimeks with his own eyes, Wang Qiu realized to his surprise that saying they were nomads was just putting money on their faces!It's almost the same as the blind beggar gang!

——Cows, sheep, and horses are the three standard configurations of nomads in Eurasia. The Chichimeks wandering in northern Mexico have none of them, and there is no alpaca, the mythical beast of the Inca in the south.The only animals they know how to raise are dogs.But no matter how much domestication and hybridization are done, it is impossible for dogs to become able to replace horses for people to ride, or to grow fatter than cattle and sheep.

Therefore, except for a few advanced elements who have learned how to grow corn, those Chichimeks who are not very good at farming can only live by hunting, fishing and gathering wild fruits.However, there are too many of them, and it is difficult to make a living by fishing and hunting alone, so they have to keep going south to rob various agricultural tribes and city-states.If you win, you can eat a few meals of the corn and pumpkins you robbed; if you lose, you will starve to death or become a slave.

But in the slave markets of the civilized city-states of various ethnic groups in Central America, the Chichimeks are the most unpopular "goods".Because they often have no concept of farming at all, not to mention asking them to do farm work, it takes a lot of effort just to get them to understand what farmland is.

Closer to home, it seemed that the military expenditure could not be reduced, and Wen Desi and Wang Qiu began to think about where to increase their income.

In the time-space trade in the past period, Wang Qiu and the others mainly had two main sources of profit: the first was gold, silver and natural gemstones, and the second was wood.In addition, there are some handicrafts, beautiful shells and other sporadic gadgets.

First of all, after two years of cross-time and space-time commodity trade in Mexico, Central America in the 16th century, the traversers got a total of nearly one ton of gold, three and a half tons of silver...plus various natural gemstones, and then After enduring a layer of exploitation from the bank acquirer, the total revenue is about 7 million yuan—but this is not pure profit. In order to obtain this money, Wang Qiu and the others must purchase astronomical amounts of modern industrial products. Millions of boxes were sold, tons and tons of salt and sugar, and thousands of steel knives, glass ceramics... In addition, the infrastructure of Port Hope (cement, color steel prefabricated houses) also cost a lot. Any small amount of money has to be squeezed out of this sum.

In addition, another major income in Mexico is naturally timber - unlike the relatively rare gold, silver and gemstones, in that undeveloped tropical rainforest, timber resources can be said to be endless, and No one sees it as anything of value at all.

Through the hard work of tens of thousands of Indian loggers who work continuously throughout the year, although they do not have buzzing chainsaws or large trailers emitting black smoke, they can only cut and drag by manpower, but after all, there are more people and more power , At least hundreds of logs are transported to the main square in Port Hope 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. As a result, starting from the beginning of August, Wang Qiu moved a dozen or even dozens of containers almost every day. After getting the wood to the dock, Ma Tong called Boss Zhou Mifan to come over to receive the goods—however, such a huge amount of wood was taken out in such a short period of time. Where can I eat them all?

In fact, when the fourth batch of "Mexican smuggled timber" was received, the boss Zhou Mifan had already been overwhelmed by so much timber and couldn't eat any more goods—although the timber was all It is a super cheap product like a pie in the sky, but because Wang Qiu and Professor Yang do not accept the deferred payment, they must immediately trade in cash. As a result, even though Boss Zhou has tried his best and even borrowed a usury loan, he has no money. Fa raised tens of millions of liquidity in just three days.

There is no way, if you want to find a buyer for such a large amount of wood, at Boss Zhou's level, it will be absolutely impossible without ten days and half a month.

Fortunately, Boss Zhou has been in the society for many years, so he still has some contacts.Seeing that the leaders of Zheng Fu were in a hurry, they volunteered to act as intermediary introducers, and found many other large and medium-sized timber merchants to sell, so that they can make a fortune together.In this way, he not only fulfilled the requirements of Zheng Fu personnel, but also earned some referral fees, or made the other party owe a favor... As a result, in late August, purchasing personnel from distant Henan and Hubei made special trips Come and see the goods.As for Ma Tong, the contact person, even his mobile phone was blown up several times.

At present, Ma Tong, who has not yet recovered from dysentery and dehydration, has to stay on the other side of the wormhole to answer the phone in order to cope with the incoming timber buyers. He has no time or energy to go to the Mexican beach to bask in the sun. Sao harassed the cute Indian girl.

And our leader Cai Rong... Uh, Luo Li's immunity is generally relatively weak. She is still receiving injections and her fever has not completely subsided.
