Tan Fei was surprised that His Majesty did not know why the "armor-removing wind" was. What Zhao Bing was worried about was the destructive disaster that this unknown disease might bring. For a moment, even flashed in his mind that if his guess was confirmed from Tan Fei's mouth, then the idea of ​​ending the war immediately and returning to Jiangnan immediately shows how afraid he is of this. This is the Black Death, which is what modern calls the plague.

Before the emergence of vaccines, plague was undoubtedly the most terrifying nightmare for mankind. Especially in history, when international commerce in some countries or regions flourished, plagues often spread rapidly around the world through trade between regions. Among these plagues, the earliest large plague that spreads widely was the Great Plague Justinian that broke out in 541.

This great plague took only one year to spread throughout Europe and the Near East without any defense measures. In a year, it claimed 15 million lives, and the subsequent plagues increased the total victims of the great plague to a terrible 50 million. The origin of the Justinian plague was the Egyptian region, an important food supply area in Europe at that time.

At that time, mice or fleas with bubonic disease bacteria were shipped to Constantinople, the capital of Eastern Rome, and quickly triggered a large-scale plague in the city. Due to the lack of effective means of suppressing the plague, and the Eastern Roman emperor Justinian was determined to restore the territory of the Roman Empire at that time, the plague immediately spread rapidly between cities and then spread from cities to rural areas.

However, this great plague naturally did not stop in Eastern Rome. In fact, with the reconquest movement of the Eastern Roman Empire and the Silk Road, the plague quickly spread to North Africa, Western Europe, Persia and other regions. This plague also completely changed the history of Europe and even the world. Affected by the plague, not only did the Eastern Roman Empire try to restore the Roman territory again and ended in failure, but also due to the consumption of war and plague, Byzantium was unable to resist the Sassanian Persian occupation of Egypt, Syria and other regions.

In Western Europe, the Justinian Plague had a greater impact, and the huge population loss directly led to the arrival of the dark age in the early Middle Ages. In England, the aftermath of the plague also completely destroyed the Celtic resistance to the invading Anglo-Saxons. If the impact of the Justinian Plague was limited to the western front of the Eurasian continent, then the plague that broke out at the end of the Mongol Empire ruled the world completely changed world history.

After the Mongols ended their military conquest, the land Silk Road, which had been abandoned due to wars along the way, was finally unblocked again. However, this not only brought huge economic benefits to the various Mongolian Khanates, but also brought great dangers. At the beginning of the 13th century, a large-scale plague broke out in Annan and Java in Southeast Asia. Since these two areas were important transit stations for maritime trade at that time, merchant ships carrying plague sailed to Hangzhou, and went north through it, and finally spread along the Grand Canal to Yuan Dadu.

As Zhao Bing knew in his previous life, this terrible plague can be said to be the first national plague in China, and its spread is almost a replica of Justinian plague. Because there is no effective means of suppression, the plague is like entering a nobody's land. In addition to being widely spread among the people, the princes and emperors of the Dayuan city in the imperial city were also infected one after another. Sixteen princes and two emperors died of the plague.

However, this was just the beginning. With the Silk Road on the way, this unprecedented plague spread back to the Chagatai Khanate, the Il Khanate, and the Golden Horde. Through the trade and war of the Golden Horde, it spread to the Ross region and the Genoese colony of Crimea. Later, the plague spread to Italy along the commercial activities of the Genoese and thus infected the entire Europe.

It can be said that the great flood of the Black Death had an unprecedented impact on the entire Europe and the entire world. The Black Death directly destroyed the Yuan Dynasty and the Il Khanate in the Middle East, and greatly damaged the remaining Khanate's vitality, and headed towards the tragedy of continuous division and shrinking territory. In Europe, the Black Death directly changed the social composition of the entire Europe.

Therefore, Zhao Bing was very clear that the opportunity for this disease to be introduced into China was the Mongols' war of conquest against Eurasia. This great plague that affected the world occurred in the world. What he was worried about was that he had changed the direction of history, that is, there is a possibility of a plague outbreak in China now. The Mongol rule was destroyed, and he also knew that the demonic shadow of the plague would also fade away, just the prelude to the era of the Black Death.

Due to the lack of effective treatment methods and corresponding vaccine prevention, the Black Death began in the 14th century, that is, in the near future, and the plague broke out randomly in any region of the Eurasian continent. The Black Death that broke out in Britain and France directly forced the 100-year-old war between the two countries, and in Britain it also led to the demise of the long-standing Praise Dynasty.

When the Little Ice Age of the 17th Century came, the Black Death reached a new peak. In the Ming Dynasty, due to the continuous outbreak of the Black Death from the end of Wanli, the Ming Dynasty's national strength and military strength were seriously damaged. Especially in the North China region at the end of Chongzhen, its severity had reached the level of "a major epidemic, thousands of miles north and south, from the outside of the border north to the Yellow River in the south, and one out of ten chambers was eliminated."

However, such a tragic situation was not limited to the Ming Dynasty. At that time, the entire human race had no way to resist the Black Death. In almost the same period in Europe, the extremely famous "Milan Plague" and the Black Death in London broke out. The former could be said to have completely destroyed the prosperity of Italy, while the latter almost caused the restoration of the Stuart dynasty to die, and led to the defeat of the Second British-Dutch War.

In Eastern Europe, the severe Black Death broke out, causing the Eastern European city to lose at least one-third of its population. In the Americas, the Black Death manifestation is even more exaggerated. This disease, along with another extremely terrifying disease, smallpox, spreading in the Eurasian continent, almost wiped out the entire American Indians. In short, the world is huddled in the shadow of the plague. Even in modern society, although effective prevention and control methods have been already provided, it is still vigilant about this as if it were guarding against a great enemy.

The biggest plague Zhao Bing experienced in his previous life was SARS. He spent a terrified life, but it seemed that death was still far from him. However, as soon as he came to this world, he experienced the outbreak of the flu and felt the fear of death being around him on the epidemic ship. Every morning, he watched the dead patient's body be thrown into the sea, and he felt that the next one could be himself.

While this experience allowed Zhao Bing to gain the team, he also allowed him to experience the helplessness of the ancient people to the plague, which caused a huge shadow in his heart. Then he listed "not allowed to urinate or defecate anywhere" as the iron rule in the army, established and improved the medical system, and paid for the improvement of environmental sanitation in Hangzhou despite the opposition of ministers. It can be said that it was out of fear of the plague and always tightened the string of epidemic prevention to prevent the plague from unexpectedly encountering the century-old plague that changed the world pattern.

After arriving in Qiongzhou, it was summer all year round, and it was so hot that it was not so hot that everyone was not interested in armor. Zhao Bing also took advantage of the situation and abandoned iron armor, only leather armor, and half-body armor. Later, with the popularity of firearms, the demand for armor was even less urgent, so he simply "invented" a lightweight protective armor with a plate-type, which was not only light but also better ventilation than armor, so he had no chance of removing armor.

Although the incident was just a false alarm, Zhao Bing breathed a sigh of relief, he still woke him up. There was no plague outbreak now, which does not mean that it would not happen in the future, and time is at a historical node. He knew that once a plague broke out, the population in Jiangnan would be denser, more likely to spread, and it would be more difficult to control. The losses would be heavier than that of Jiangbei, Central Plains, and grasslands, which had sparse populations, and the restoration of the country would become an unrealized dream.

Zhao Bing pondered for a moment, picked up his pen and wrote a command, and ordered the troops participating in the war to deal with the battlefield immediately. Whether it is the person who was shot and left on the battlefield, the body of the horse or the enemy's heads captured by the merits, it must be cleaned up in time, and buried deep in a place far away from the water source to cover it with quicklime. The camp should also further strengthen hygiene and try to ensure that officers and soldiers can take a hot bath to remove the breeding fleas and lice. In addition, mice in the kitchen and granary should be eliminated to cut off the source of infection as much as possible.

After Zhao Bing finished writing, he felt uneasy. Now it was the time when merchant ships from all over the country came to the Song Dynasty to trade, and it was also one of the sources of infectious diseases. So he wrote again to write the imperial edicts of the Shangshu Province and the prefecture chiefs of the port, Guangzhou, Quanzhou and Qiongzhou, respectively, asking them to strictly inspect the maritime merchants and sailors from foreign merchant ships, especially ships from Annan and Java. Both their own and foreign ships were no exception.

Anyone on board who finds fever, coughing up blood, coma, hallucination, diarrhea, skin ulcers, subcutaneous bleeding, armpits, and unknown lumps on the neck are not allowed to land, and ships are not allowed to move to the port. After five days of observation, there will be no abnormality before they can be released. However, those who find that the affected area of ​​the patient's skin turns blue and black will be isolated, and no one is allowed to approach. Once they die, the body, the ship and cargo they are on will be burned.
