The Qin army and the Shu army fought a decisive battle in the Sanjiang region. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The two sides have invested more than 500,000 troops, although the Shu army is relatively passive, but it occupies a geographical advantage.

The Qin army was trapped in the shallow wetlands, and after approaching the Neijiang River in the Shu army's base camp, the two sides confronted each other across the Mengxi River, and it was difficult for the Qin army to break through.

When summer came, the scorching heat and humidity affected the Qin army.

This brought the two sides into a stalemate, which gradually protracted.

The two sides began to confront each other on both sides of the Mengxi River.

A serious problem began to affect the Qin and Shu armies. Hundreds of thousands of people are piled up in the wilderness without any facilities, and the problem of sanitation is highlighted in the humid and hot summer.

Bacillary dysentery began to circulate within the Qin army.

Bacillary dysentery is a disease in which bacteria infect the human body through the digestive tract, causing inflammation and ulceration of the colonic mucosa and releasing toxins into the bloodstream. The clinical manifestations mainly include fever, abdominal pain, diarrhea, tenesmus, mucus pus and bloody stool, accompanied by systemic toxemia symptoms, and in severe cases, it can cause septic shock or toxic encephalopathy, resulting in a high mortality rate.

Bacillary dysentery, which can be transmitted by mosquitoes and flies, is therefore a type of plague.

Since the Qin army has a complete set of epidemic prevention monitoring system, it is still early to discover.

"The source of infection must be cut off." Hu Mingdao.

Lao Jia Xu asked, "Where is the source of this disease?" ”

"Most of them are excrement as the source, with flies as the medium, and they spread rapidly, and if they are not carefully handled, they are very prone to large-scale outbreaks of plague." Medical administrator Hu Ming explained.

When everyone heard that the fly was the medium, their hearts were shocked. Flies are creatures, don't look small, they are too strong, they are numerous, and they multiply in excrement.

Qin Feng nodded constantly, and said, "Yes, these are easy to breed flies, flies are extremely perverted insects, and a pair of flies can have 190 million offspring." Human food, secretions and excreta of humans and livestock, kitchen scraps and other garbage, and plant juices can be used for feeding. After the flies are full, they will be excreted in as little as a minute or two. It vomits and defecates frequently, loses more water, and prompts it to eat frequently, so it eats, vomits, and pulls on the biomass, causing serious pollution. ”

Eating while pulling, this is too dirty, and the civil and military are all shocked.

"That's it, that's it, what the king said is too good, so reasonable!" Hu Ming danced with his hands, and as a comprehensive health official, he hurriedly took out a pen and paper, recorded it, and said: "What the king said is too scientific, we didn't know about it before." ”

The crowd was even more shocked.

If you want to say how Qin Feng knows, you have to thank the animal world in later generations.

"Then the king, how to cut off the source of infection?" Lao Jia said with a trembling white beard.

"Buriable."

Everyone immediately obeyed and celebrated, the king's idea was too good.

As a result, the Qin army began to implement strict and compulsory hygiene, mandatory hand washing, forced drinking of boiled water, and the prohibition of any open 'poop'. The soldiers in the army took the battalion as a unit, dug pits and buried all the 'poop', and hunted and killed mosquitoes and flies.

Because the Qin army implemented the measures in a timely and appropriate manner, the cases quickly decreased.

The day after.

Zhuge Liang, the commander of the Shu army, accompanied by Guan Yu and Zhang Fei, the front-line general, sat in a small cart and came to the Shu army-controlled area on the north bank of the Mengxi River to inspect.

Squeak and twist~.

Zhuge Liang pointed to the shore, and the soldiers hurriedly pushed the cart over, and all the generals followed.

Zhuge Liang set up a pergola with a feather fan, and looked at the opposite bank, and saw many Qin troops holding tools and launching an attack on the ground, and dust was everywhere.

"What's going on?" Zhuge Liang asked.

Wang Ping, the garrison general here, said: "Prime Minister, your subordinates are also wondering. ”

Zhuge Liang looked at it carefully for a while, smiled, and said: "The Qin army must have an outbreak of epidemics, this is digging pits to bury excrement, this is epidemic prevention." ”

When the enemy is plagued, the people rejoice.

Zhuge Liang was also happy in his heart, but at the same time he was vigilant, so he asked, "How is the situation of our army?" ”

Everyone naturally knew what Zhuge Liang was asking, and they were really asked. If Zhuge Liang hadn't asked, no one would have asked about it.

So the heralds scattered in all directions.

On the afternoon of this day, Zhuge Liang was in his base camp and received a report from the military doctor of the Shu army.

"Cheng ...... Prime Minister, if you want to talk about epidemics, infectious diseases ......, our army's medical battalion has treated 58 cases of dysentery. The military doctor added: "There are no other infectious diseases for the time being, only dysentery." But dysentery is very intractable, difficult to cure, and contagious. ”

Zhuge Liang contacted the situation of the Qin army he saw on the shore earlier, and said, "Is it infected through excrement?" ”

The military doctor said: "It is mainly transmitted through excrement, and flies are vectors. ”

When you think about it, you can understand that flies bite excrement and circulate around people and food, and it will naturally be contagious.

So, coincidentally, Zhuge Liang also ordered that compulsory sanitation work prohibit all 'poop' anywhere, and take the battalion as a unit, and all the poop will be dug and buried.

In the ensuing time, the scorching heat, humidity, drearyness, and confrontation became the main theme of the battlefield.

In this environment, both the Qin army and the Shu army chose a temporary truce.

For a time, there was no smoke of gunpowder and shouts of killing on the battlefield, but there was the sound of shouting trumpets and digging pits everywhere.

But soon, half a month later, an unexpected situation appeared.

The number of new cases of dysentery in the Qin army has risen geometrically.

King Qin was shocked and urgently ordered to find out the cause, and soon the cause was found out.

"What, there's nowhere to dig a hole?" When King Qin got the news, he stood up in shock.

Lao Jia Xu reported the difficulties, "King, our army has more than 300,000 ....... ”

The situation is probably like this, the Qin army is hundreds of thousands, hundreds of thousands of people need poop a day, because the Qin army has good food, some people still need to poop several times a day, and after a long time, there is no place to dig pits and bury them.

In fact, there has been a set of effective methods for garbage disposal in marching battles since ancient times. However, the environment in the Sanjiang area is too humid, humid and hot. In such an environment, conventional treatment methods fail, and the only way to bury them is to dig a pit.

Places are finite and cannot be sustained these days.

After the cases exceeded 10,000, the generals of the military division saw that the situation was not good, and they were unable to defeat the enemy, so they all persuaded Qin Feng to retreat.

"Think about it."

By the next day.

When Wenwu came to the temporary palace, he heard the sound of clanging.

Jia Xu, Pang Tong and others saw that King Qin was working with his sleeves rolled, holding a hammer and beating a wooden box.

Dangdang~.

Qin Feng fixed the last nail and the last piece of wood, showed it, and said, "Everyone, what do you think of this thing?" ”

I saw that this thing in Qin Feng's hand, infinitely close to the ammunition box of the later generations, was all nailed with wooden planks and hollow, but it was not completely sealed, but in the upper part, there was a big hole.

A wooden chest with a hole in the top, what is it for?

Jia Xu, Pang Tong, Xu Huang, Zhang He, Lu Bu and others are all full of question marks.
