After resolving the crisis in the underground party, Xiang Nannan returned to Bailuyuan.


    And found Mr. Leng and asked him about the reserve of medicinal materials.


    Mr. Leng listened to Xiang Nan’s suggestion and has been stocking up on medicines for the past two years.


    ?It''s just that his personal financial resources are limited, and there is a severe drought in the world. Not only the food harvest is cut off, but the production of medicinal materials is also affected, so there are not many medicinal materials saved in total.


    "No, we still need to save more medicine." Xiang Nan said to him.


    “Little fairy, tell me why you need to save so much medicine?” Mr. Leng asked doubtfully.


    “After a major disaster, there will be a major epidemic.” Xiang Nan explained.


    Catastrophic disasters can cause large numbers of deaths and lead to imbalances in social order.


    A large number of people die and the social order is unbalanced, which will prevent the bodies from being buried in time. The rotting and deterioration of exposed corpses will lead to the growth of a large number of germs.


    Furthermore, the movement of disaster victims will also lead to the spread of germs. Chinese people have relocated to their new homeland, and are unwilling to leave their hometowns unless there is no way to survive.


    Therefore, even if there are infectious diseases, because the scope of people''s activities is limited, they are often limited to one village, one township, or one county. But during the famine, the victims fled everywhere, spreading the germs everywhere.


    In addition, during major disasters, the human body''s immunity will also be greatly reduced. Just like the victims of the disaster, they were all malnourished and skinny. They could easily survive the diseases that they usually could withstand.


    Therefore, after a great disaster, there will be a great epidemic.


    “Plague?!” Mr. Leng was startled.


    ?As a doctor, he knew how terrible the plague was.


    If the lethality of hunger is one, then the lethality of plague is one hundred.


    A living person who only drinks water and does not eat for three to five days will not be in danger of life. But if you contract the plague, even if you have diarrhea, you will die within two or three days.


    Therefore, hunger alone is not enough to wipe out the entire population, but the plague may cause the tragic phenomenon of "no roosters crowing for thousands of miles, and bones exposed in the wild", which can be said to be a hundred times more terrible than drought.


    “Is there really going to be a plague?” Mr. Leng confirmed.


    "There will really be a plague." Xiang Nan nodded, "Hu Lie La, if we don''t treat it in time, at least half of our village will die."


    Mr. Leng suddenly looked stern.


    Horaela is the common name, and the scientific name is also called cholera. This is an acute infectious disease. Patients will suffer from severe diarrhea and vomiting, leading to dehydration, electrolyte imbalance and muscle spasm. In severe cases, circulatory failure may lead to death.


    In ancient times, the mortality rate was close to 50% to 60%, and in severe cases, it could even reach 80%. It can be said that if it is not handled well, the annihilation of villages and ethnic groups is certain.


    "Okay, I''ll save the medicine right away." Mr. Leng nodded.


    Xiang Nan also took out a bag of ocean and handed it to Mr. Leng, "The villagers from dozens of miles around are all relying on you."


    Mr. Leng took the money and nodded.


    ?Human life is at stake, and at this moment, he can no longer afford to be polite to Xiang Nan.


    …


    June is coming soon, and the harvest of corn, sorghum, and millet is about to begin. God also rained a few more times at the right time, making the seeds swell more and more.


    The villagers are also very happy, thinking that this year will definitely be a good year. In this way, they no longer have to go hungry and finally feel relieved.


    I didn’t expect that the harvest was about to be harvested. Suddenly, a large swarm of locusts appeared out of nowhere. They were a large black mass, like dark clouds, covering the sky and the earth, blocking out the sun.


    Wherever it went, trees, weeds, crops, and even the window lattice paper were all eaten away. After the locusts passed through, there was almost nothing left in the land, and everything became bare.


    ?The harvest was about to be harvested, but when such an unexpected incident happened, the villagers just wanted to cry without tears.


    “How could this happen? God, are you going to give the people a way to survive?”


    "My corn, my sorghum, God, aren''t you kidding me?" "After the drought, there is a locust plague again, God, please give us a way to survive!"


    ??The villagers couldn''t help crying and felt that fate was really playing tricks on people. The drought finally passed, but unexpectedly there was another locust plague, leaving no way to survive.


    …


    At this time, people remembered Xiang Nan''s prophecy again.


    Two years of severe drought, half a year of locust plague, and half a year of plague.


    Now that droughts and locust plagues have come true, the plague is not far away.


    ?Thinking of this, the villagers are also uneasy and anxious all day long.


    “Hei Wa, is there really a plague?” Bai Jiaxuan found Xiang Nandao.


    ?Now the people in the village are extremely afraid, fearing that they will catch the plague at some point, so they dare not even touch the sky these days. He said that he would die at some point, so what else would he be doing farming?


    ?And this kind of sentiment obviously should not spread, otherwise, before the plague comes, everyone will dig their own graves first.


    "Really." Xiang Nan nodded, "Hulie La, at least half of the village will be dead by then."


    "So many?!" Bai Jiaxuan was startled and asked quickly, "What should we do? Is there any way to save them?"


    "Yes." Xiang Nan nodded, and then came up with ten strategies to prevent and control the plague.


    In fact, cholera is not a terrible disease and has been extinct in many areas. Cholera still exists only in remote and backward areas with poor medical conditions.


    ??Moreover, as long as you take precautions, this disease can be easily prevented.


    Bai Jiaxuan took it and took a look, and saw that it included drinking hot water, eating cooked food, washing hands frequently, cleaning the streets, cleaning water sources, feces, killing mosquitoes and flies, disinfecting such as vomiting, diarrhea, timely isolation, etc. It is not difficult to do it. .


    “Can this be enough?” Bai Jiaxuan asked.


    “As long as we do these things well, we can prevent at least 80% of the risk.” Xiang Nan explained.


    ?Bai Jiaxuan nodded.


    Being able to defend against 70% to 80% of the opponents is pretty good.


    ?He then posted the prevention notice and asked children to make it into a children''s song.


    “Huliela is not scary. Drink hot water and eat well. Wash your hands frequently and cut your nails..."


    After some publicity, the villagers finally felt at ease.


    ?Many people follow these instructions, but there are also careless and idle people who do not follow the ten preventive measures.


    ?So soon, Bai Xing''er, who was responsible for breeding animals, began to suffer from diarrhea. Within two days, he fell on the kang and could not get up.


    Xiang Nan went over and saw that it was Hu Liela.


    "Have you washed your hands, cut your nails, drank hot water, eaten raw food...Do you feel uncomfortable, deserve it or not?" Xiang Nan asked.


    ??Bai Xing''er just didn''t take the ten epidemic prevention measures seriously. He drank raw water and ate raw food. He still couldn''t stay in the village and always went to other villages. As a result, the news has spread.


    "Little fairy, I don''t dare anymore. Please save me quickly, please." Bai Xing''er begged for mercy repeatedly.


    He had to run four times and almost lost his strength.


    Xiang Nan then helped him get medicine, and also ordered people to seal the door of his house, and no one was allowed to go in, and he was not allowed to come out. After seven days, the seal can be opened.


    ??If you dare to expose it privately, you will become the enemy of the whole village and will be subject to family law.


    ?After this incident, the whole village was frightened and no longer dared to take it seriously.
