Zheng Lang looked at the letter, fever, coldness, and sweating, it was malaria, not some miasma.

Zheng Langzhen can't say clearly about the miasma, but it's also not easy to deal with malaria. In a short time, Zheng Lang thought of the Battle of Baiteng River and the later Battle of Jiaozhi of Guo Kui's Southern Expedition. They were all held back by this thing.

Zheng Lang's face became ugly. In this hot day, I drilled back and forth in various states and counties, not only to see the situation in each state and county, as well as the related water conservancy, but also to tell the world that as long as you pay attention to reasonable living habits, even if it is a miasma area, you will be safe.

Without the threat of miasma, the common people would no longer regard the south as a daunting path, and would be willing to migrate to the south on a large scale, instead of the thousands of families they have now. If you want the two Guangxi to have a big look, at least 200,000 households will have to be relocated in the next two years. Even 200,000 households are far from enough, and if you want to see popularity, at least 2 million to 3 million households in Liangguang and a population of more than 10 million to 20 million, then it makes sense to smash these 60 million yuan.

Subsequently, the pressure of overcrowding on Fujian Road and Liangzhejiang Road to Jiangnan West Road will be lightened.

But if this news spreads, I don't know what will become of it when it reaches the north, and it will be difficult for 200,000 households and 20,000 households to get it.

"Malaria," Zheng Lang whispered.

Zhou Xin also took this information and watched it, and his expression was not very good. Di Qing's military operation was not hidden from him, if according to the original military plan, wait for Anon to gather a little manpower, just Zhao Xun arranged the affairs of Temo Dao properly, the army gathered, went west, carried out the final blow to Anon, and then attacked Sanjiangkou and threatened Dali. It's not really to eliminate Dali, it's to carry out intimidation. Moreover, during this period of Dali, Silian relied on the Gao family to suppress the Yang family. After all, he ascended to the throne because Duan Suxing was mediocre, and the Gao clan deposed him and established Duan Silian on the throne. Many powerful people in the country are not convinced. The turbulent situation in Dali determined that Dali would bow its head in the face of the strength of the Song army. can force Dali to sign some treaties favorable to the Song Dynasty with the Song Dynasty, at least let Dali restrain his subordinates. It is no longer acceptable that some tribes in the south of Kuizhou Road have repeatedly defected. As for Dali itself, Zhou Xin is not interested, and Zheng Lang is not interested.

This unexpected situation can be described as terrible.

He asked hesitantly: "Zheng Xianggong, aren't there some measures?" ”

"It doesn't work if you have it, it is estimated that Di Qing is chasing Anon and marching fast. You can't do everything I tell you to let mosquitoes bite. Not miasma, but malaria. Since the beginning of Temo Road, there are sparsely populated and there are many poisons, and there are many things in many areas, resulting in a large amount of filthy land on which mosquitoes live. If it grows on it, it carries more germs, and it is more likely that people will develop malaria after biting. ”

"What are germs?"

“…… Zhou Fuzhi. Let me think about it. ”

After thinking for a while, he first wrote a letter to Zhao Xun, asking him to screen the prisoners of war, some of whom were prisoners of war and tribes who were bewitched by Anon, and those who had the heart of repentance, especially the tribes surnamed Wei Zhou and Huangsan, all of them should be let go and not escorted to the Central Plains again. However, it is necessary to pay attention to balance, not to let one surname dominate, and to form a situation in which the number of four surnames is about the same. Due to the Song Dynasty's support for the Nong family, the second surname gradually declined, and these two surnames can be further relaxed.

He also wrote to Di Qing, asking him to report the details of the situation, and not to move the garrison in Keyan, and to treat the soldiers suffering from malaria as much as possible. But isolate yourself. The two letters were sent to the West, and they sat down again and thought nonsense. He didn't think of Ge Hong's sentence in "Elbow Reserve Emergency Prescription", but he thought that artemisinin seemed to be related to ether. The low boiling point of ether is known, but the high boiling point of water destroys some of the components in Artemisia annua, or produces some chemical reactions with ether.

It's hard to think like this.,Lack of information.,Even if it's not easy to check from Du Niang in the previous life.,Theory is one thing.,It's another thing to do it.。 Holding the psychology of a dead horse as a live horse doctor, he first wrote a letter to Shi Heng, asking Shi Heng to transport a batch of sulfuric acid as quickly as possible. …,

It's not too slow.

There are several official roads to Lingnan in the Song Dynasty, one is a waterway, from Jiangzhou to Jizhou along the Ganshui to the south, from Jizhou is not a smuggling salt road, but to take the Da Gengling Road, also called Meiguan Ancient Road. It was Zhang Jiuling of the Tang Dynasty who returned to his hometown, returned to Shaozhou to see the rugged mountain road of Meiguan Ancient Road, wrote to Xuanzong of the Tang Dynasty, and took advantage of the agricultural slack season to use the ancient road opened by the people. From Da Gengling Road to go straight to all parts of Guangzhou. This road is easier to walk, but the journey is slow.

There is also a road, from Yingzhou to Tangzhou, Xiangzhou, Jingzhou, Ezhou, Yuezhou, Tanzhou, Hengzhou, Zheng Lang went south half of the way is this road. When arriving in Hengzhou, it is divided into two routes, one is to go to Chenzhou, pass through Tianling to Guangzhou, and the other is to go to Yongzhou to Guizhou. This is the post road, also known as the official road.

If Zheng Lang succeeds in the development of Liangguang, it will not be these two roads, and there will be seven or eight commercial and official roads to choose from. But now there are only two, if you want to be fast, you still choose the dry road behind. Although the cost of transportation will be higher, it is all dry roads, and horses can be used all the way, and the speed is more than twice as fast as before.

The document delivery is a delivery shop, because the Song Dynasty raised a large number of box soldiers, and it was necessary to place some veterans and hand over the work of the delivery shop to the soldiers. Moreover, the Song Dynasty delivery shop is both wide and dense, not like the Tang Dynasty with the state as the center, but with the county as the center, radiating in all directions, there is a delivery shop in 25 miles. However, the south does not pay much attention to it, and the scale of the delivery shop is much smaller, but on these two main roads, especially on the latter road, many delivery shops have southern horses. There are steps in the delivery of documents, including water delivery, horse delivery and express foot delivery. The minimum speed of horse delivery cannot be less than 300 miles per day, and it is not the fastest, but the fastest is urgent foot delivery. This is a delivery method used to convey tight military information, changing horses all the way, and even changing horses and people, day and night. The speed requirement should not be less than 400 to 500 miles per day. If you change people and horses on the main road, it can often reach seven or eight hundred miles, which creates the miracle speed of the Song Dynasty when Nong Zhigao rebels, and the news of Liangguang will be sent to the capital in five or six days.

Zheng Lang used the method of urgent foot delivery, so that the sulfuric acid could be transported to Guizhou at a constant speed.

Then he wrote a letter to the governor of Hongzhou, asking the governor of Hongzhou to immediately arrange for Hongzhou craftsmen to fire a batch of medicinal jade and transport it to Guizhou, and draw the style, mark the size, and there must be some translucent properties. The glass manufacturing process has been transmitted to China very early, but it has not been able to burn the transparency of glass, but it has become another process, glass, just like China's cloisonné to the Wa Kingdom, it has become Qibao burning. Some glass is full of brilliance, but it cannot be used because it is completely opaque. There are many medicinal jade workshops. Hongzhou also has it, and it must be made clear.

He also sent people to Lingnan to collect a large number of Artemisia annua.

It just so happens that Lingnan Artemisia annua is in the flowering season, and the medicinal effect is relatively good, so I want to be good. And move it back, preferably in August. But Artemisia annua at the time of flowering can be used. The Artemisia annua flower season in Lingnan is early, and if the growth time of Artemisia annua is different in different places, the actual Artemisia annua flower season can start in May and end at the end of September. This is also the time of high incidence of malaria.

I don't know if this method will work.

I thought of some other methods, and felt that it was available, so I sent someone to deliver it to Keyan in a hurry. There are not only soldiers, but also his student Sima Guang and the future Hebei No. 1 brave general Zhang Yu, neither of whom can afford to miss a miss.

Even if it was a soldier, Zheng Lang didn't want them to make a mistake, and after several battles, these soldiers became veterans. In the future, if you don't fight with Jiaozhi, you will also march into Meishanman. These soldiers are the main force of the battle. It doesn't work to transfer the forbidden army, can it quickly adapt to the mountainous terrain of the south, the humid and hot climate?

Zheng Lang didn't have the heart to go on patrol. Starting from Hezhou, passing through Zhaozhou, and coming to Guizhou.

Before entering the city, he came to the Li River, where he built an academy. But it is different from Juyang Academy, and different from the later four major academies of the Song Dynasty, to be precise, it should be called the College of Ethnic Minorities. More than 1,100 students were recruited, and nearly 600 of them were sons of the heads of various departments. There are also hundreds of sons of martyrs and more than 100 local children of Guizhou. Barbarians of various races account for more than ninety percent. …,

After its establishment, Yu Jing felt that there were too many recruits.

Zheng Lang said: "If it weren't for the financial resources and teachers, I hate to recruit all the barbarian children into the school together, then in just twenty years, there will be no more barbarians and Han people in the south." ”

Yu Jing heard the last sentence. There was no silence.

Its main role is to sinicize the two Guangzhous, Zheng Lang also wrote a memora for this, after the Xianbei people went south, the north was a Huyin. Since the Northern Wei Dynasty took the initiative to sinicize the Xianbei people, is there any Huyin in the Central Plains now? In fact, in the north, there are many people with the blood of the Xianbei people, and even Zhao Kuangyin's ancestors may have been related to the Sinicized Xianbei people, but were there any ethnic contradictions in the north later?

Fusion, family, talk about contradictions.

That's what Zheng Lang has to do in the south. Including the clothes, the first thing to do when entering the school is to wear the clothes of the Confucian students of the Han family, which the barbarians do not reject, on the contrary, they admire very much. After entering the school, they were taught Jingyi and arithmetic, and at the same time taught them the living habits of the Han people.

The first batch of barbarians to enter the school will be reused, and those who can succeed in the imperial examination will be allowed to take the imperial examination, and those who cannot succeed in the imperial examination will be placed in the prefectures and counties one by one, let them serve as grassroots officials, and let the barbarians take the initiative to participate in the affairs of the two Guangxi and Guangxi, and further integrate. But now you have to study for a year or two, know some scriptures, and be able to calculate and write.

Zheng Lang allocated another 80,000 yuan, which is a huge amount, if it is in the capital, the price may not be expensive, but in Guizhou, 80,000 yuan is an astronomical amount. With 80,000 yuan to build a huge academy, there are thousands of dormitories, 100 classrooms, a library, more than 200 staff dormitories, plus a large playground of 1,000 square meters, a large garden of several hundred square meters, a small artificial lake covered with stones, and a small island in the lake, and a pavilion on the island. The architecture and scenery are all several times better than Juyang Academy.

It was not until the end of April that the academy was completed.

The only thing that made Zheng Lang dissatisfied was the problem of teachers, and he spent a lot of money to invite only two hundred or dozens of people who did not have a middle class. Not a single famous Confucian was invited. There is no way, Zheng Lang wrote to Yu Jing on Guangdong South Road, brother, you are a little wronged, and you can take the time to teach these students. What should I do, the whole Guizhou is the best in terms of your knowledge, and you are from Shaozhou, so everyone does not reject you.

Seeing Zheng Lang's arrival, teachers and students greeted him together.

Zheng Lang asked everyone to combine in the playground, and asked the guards to bring his guqin, singing while playing the piano: "

The orchid is rampant, and its fragrance is promoted. Don't pick and admire, Yu Lan is hurt.

Today's rotation is true. I go in all directions, day by year.

Snow and frost trade, the majesty of buckwheat. If the son is not hurt, I will not look at it.

The majesty of buckwheat, the presence of buckwheat. The wound of a gentleman, the guard of a gentleman. ”

This is written by Han Yu, and it is a fanfic version of Confucius's "Youlan Cao", but this fanfic version is better than the original version in terms of literary attainments, although the author of the original version is a Confucian sage. Zheng Lang's singing voice is not very beautiful, but this song "Youlan Cao" is very ethereal, and it also makes people feel like heaven.

This song expressed his heart and resonated with Zheng Lang.

Zhou Xin listened to Zheng Lang's piano and Zheng Lang's singing, and suddenly, he finally understood Zheng Lang's inner world at this moment.

Silently looked at Zheng Lang on the stage and said: "Xingzhi, if you are a buckwheat, you are the most brilliant one in the world." ”

Yu Jing glanced at Zhou Xin, who was full of emotion, and did not make a sound. Disagrees with Zheng Lang's politics, but Zheng Lang's moral conduct cannot be denied. But I thought in my heart, Zheng Xingzhi, how can you resolve the crisis in Keyan this time?

After Zheng Lang finished singing, he said: "This four-character ancient poem was written by Han Yu in the Tang Dynasty, and he had a lot of political achievements when he knew Chaozhou, and you southerners also miss him." It is sung today, not so that you mourn him, but to understand its meaning. Learning, not only to learn to ask, but also to learn how to be a man and a gentleman. As beautiful as an orchid, like buckwheat, it can be full of vitality and bloom with dazzling brilliance despite any severe cold and difficulties. When I settle down, I will come and give you lectures from time to time. Today, I will tell you about the chapters and verses of the Analects on how to behave. The first sentence is a paragraph in "Yongye", the life of a person is also straight, and the life of recklessness is also spared. People must be upright, only upright can be above board, and the unrighteous people around us can survive, and that is only because of luck to avoid disasters. This kind of luck will not last long. The same is true for learning, there is no ingenuity, only two words, hard. There is a diligent path in the book mountain, and there is no end to the hard work of learning the sea. The learned ministers of the dynasty, whether Fan Zhongyan, Ouyang Xiu, or others, all the young people studied hard, and this is what they have today. Even if I was a little successful, I also studied hard for many years when I was a teenager, and even closed myself for several years. So far, I don't dare to put down the book, and I can't release the book, lest I lose my knowledge......"

Along the way, we will talk about benevolence, morality, preaching, stressing rigidity, perseverance, wood, ne, gong, generosity, faith, sensitivity, and hui, and talking about the six arts.

It wasn't until dusk that Zheng Lang announced that everyone had dispersed in a hoarse voice.

Zheng Lang attaches great importance to how to behave. can't be a person, the better the knowledge, the greater the harm, such as Cai Jing, Qin Hui, and Li Linfu.

In the midst of onlookers and looking up, Zheng Lang left the academy with Zhou Xin and the Guizhou officials who rushed to hear the news.

Walking on the road, Yu Jing whispered: "Xingzhi, I just received information from General Di that our army has killed more than 700 soldiers in Keyan. ”

After a few more days, the entire army was infected with malaria, and it was normal for more than 700 people to die, but Zheng Lang glanced at Yu Jing, because Di Qing killed Chen Shu and other thirty-two generals, Yu Jing somewhat hated Di Qing. Keyan was threatened by malaria, and he didn't know what Yu Jing's mood was.

looked at it, but didn't see Yu Jing's expression. Zheng Lang thought to himself, after the failure of the Qingli New Deal, these gentlemen are also adults.

He asked, "Are Zhang Yu and Sima Guang okay?" (Your support is my biggest motivation.) )
