After Chen Shouxu came out of the army, according to the schedule, he went to the farm under the research institute.

As the number one leader, Chen Shouxu basically does not interfere in business that is not directly in charge of him. In addition to the army, his energy was devoted to the three departments directly under the ruling government: the Research Institute, the Health Bureau, and the Department of Industry.

Shortly after the founding of the People's Republic of China, Chen Shouxu enclosed a large piece of land for the institute in the upper reaches of the Jincheng River. He planted the plants brought by the fleet from South America, and hired the best Chinese farmers in Jincheng to take care of these precious plants.

The research institute is a semi-official and semi-private institution, and with the current level of science and technology mastered by Jincheng, it is much behind China, not to mention catching up with the European powers. In order to motivate the enthusiasm of the R&D personnel, Chen Shouxu asked for 30,000 taels of silver from Nanyang Bank and set up an investment fund. No matter who you are, as long as you send your project to the research institute for review, you can get a start-up fund. Chen Shouxu is in charge of the research fund himself, and he may not know if the project will succeed in the end, but he can at least have the ability to kill most of the unreliable projects.

The dean of the research institute, and now the dean of Jincheng College, Vasaki. Concelus was talking to Chen's secretary, Lynch. In front of them, Chen Shouxu walked down the nursery and gently stroked the cinchona seedlings with his fingers, as if caressing a lover. In the far part of the nursery where he is located, cocoa, rubber, cotton and other seedlings are also growing very well.

He waved Concelos over.

"Dean Concelos, how many saplings are there in this cinchona tree?"

Vasak. Concelos: "Your Excellency, there are now 1,024 seedlings, and we have registered each of them, and we have recorded the growth of the seedlings every week. ”

Chen Shouxu was very satisfied: "Very good, Mr. Dean. If there is any difficulty, say to Lynch, and we will find a way to solve it together. ”

Concelus: "Your Excellency." I just had a request. ”

Chen Shouxu will be happy that the large-scale planting of cinchona trees will be one of the biggest guarantees for the future expansion of the country, and the research institute has done a good job.

"Mr. Dean, just said."

Concelos: "Your Excellency, as you know, Jincheng College and Research Institute are currently short of scholars and teachers. Jincheng is not far from Macau, and I would like to apply for another grant to go to Macau to recruit more talent. ”

Chen Shouxu glanced at Lynch, "Write it down." Dean Concelos, I will support you in recruiting people in Macau. But you have to be clear that the current mainstream faith of the Jincheng military is Protestantism, and I don't care who you recruit, and I can't affect the unity of the country in terms of faith. ”

Concelos: "I'm a Catholic, but I'm more of a scholar. Jincheng gave me a good platform and I know what to do. ”

Chen Shouxu nodded. Since that expedition to Tierra del Fuego, he and Concelos have developed a relatively good personal relationship. In his free time, Chen Shouxu also discusses some mathematical and physical problems with Concelos. In addition to his academic convenience, Chen also gave Conceuros a class that he could not reach in the Spanish Empire.

Gu Shan led the horses, and Chen Shouxu stepped on the stirrups and got on the horse, "Okay, Mr. Concelos, money is not an issue. I can give you 3,000 pesos first, and don't limit your eyes to Macau, Manila, Goa, and the British. But the most important thing you have to do right now is to take care of these plants, not only cinchona trees, rubber trees and other agricultural products. ”

Vasak. Concelos: "We'll do it, don't worry." ”

"Mr. Dean." Chen Shouxu greeted slightly.

"Your Excellency." Concelus returns the favor.

Chen Shouxu pulled the horse's head and walked on the road back to the city. After the stone grinding that crushed the road, several slaves saw him coming and hurriedly retreated to the side of the road.

Chen Shouxu did not interfere too much with the planning of the city, and only said one sentence at that time, either it will not be built, or it will be built.

It was Marmont who was in charge of the construction of the city, and he still chose the most familiar routine, the construction of Spanish colonial cities. Underneath him, the design was carried out by an architect named Gucci, who came from Milan. According to Marmont, Gucci's best expertise is in the construction of grand buildings such as theaters, town halls and churches, but there is no such need in Jincheng, so he first assigned Gucci the task of designing municipal roads.

The highway between Jincheng and the naval base and the two guard forts in the south is the focus of transportation construction. The road is made of mud and gravel, and the width can accommodate two heavy wagons in parallel. In order to facilitate drainage, the roadbed is higher than the ground, and drainage ditches are dug on both sides of the roadbed and street trees are planted.

The construction of the mud and gravel pavement is relatively simple, and the two sections of the road have basically been completed, and only some finishing works remain. The road works were contracted by the Lin family, and except for some of his private soldiers who joined the army, the rest became overseers of road construction. It was the prisoners of war and slaves who toiled under the leather whip.

In the classical era, any infrastructure construction inevitably cost human lives. Many of the projects currently being promoted in Jincheng are rapidly consuming the working population, which is why Chen Shouxuan insisted on the army to send troops despite the difficulties.

Back at the consul's residence, Chen Shouxuan asked Lynch to summon Giovanni, the director of the health bureau and director of Jincheng Hospital, despite the fact that it was already dark. Tornatore. If you count the part-time job in the medical department of Jincheng College, Giovanni now wears three hats. In the hospital, he was busy treating patients and saving people, in the health bureau he was busy building various epidemic prevention stations, and in the college he had to take students, and he was also busy as a dog.

When Giovanni came in, Chen Shouxu was eating. Dinner was simple, with only a bowl of mixed vegetable soup on the table, a plate of steamed fish, and a few plates of fruit and rice. He has never asked too much for food, and he will definitely not refuse to have good food, and he can settle for that kind of person if he doesn't have good food.

Chen Shouxu saw the beads of sweat on Giovanni's forehead, and pointed to the two dishes in front of him with chopsticks, "You haven't eaten yet, come and eat together." ”

Giovanni glanced at the dish on the table, "I've eaten it, sir." ”

Chen Shouxu didn't pay attention to the strange expression of the hospital director, "Oh, I have coconut juice, tea and wine here, you can pour it yourself, feel free." ”

It was indeed very hot and humid, and Giovanni poured a large cup of tea.

"How is the progress of the preparation of the two health service regulations?" Chen Shouxu asked while eating. He didn't want to delay the monsoon season and thus delay the army's troops. In the sailing era of Southeast Asia, if you miss the monsoon period, it means waiting at least half a year.

"According to the naming and classification of adults, we have summarized the common epidemic symptoms and sorted out some treatment options. In this regard, several doctors in China have helped us a lot. We're verifying the prescriptions they brought, and some of them do work. ”

In the 17th century, traditional medicine in the East and the West was not able to distinguish the causes of various diseases, but it had a certain summary of the symptoms. Chen Shouxu named each disease according to their description of the symptoms and noted the cause he knew. Chen Shouxu did not try to convince doctors of different nationalities of his conclusions by convincing doctors of different nationalities with his authority, but simply used his authority to forcibly instill the causes of various diseases he knew, and on this basis, established a certain prevention and treatment mechanism.

Malaria, dysentery, plague, influenza, tuberculosis, typhoid, smallpox, measles, pediatric diphtheria, syphilis, etc. There was no cholera and yellow fever in Asia at this time, and malaria was the most lethal of these diseases.

The plague was violent, but it wasn't all the time, and malaria plague plagued people almost all the time. At this time, mosquito-borne infectious diseases are a worldwide problem. It may be difficult for future generations to imagine how much a small mosquito will restrict the expansion of human beings.

"Wait a minute", Chen Shouxu quickly finished eating, folded the empty plates, and sent them to the plate recycling point. Someone there would put away his plate and wash it with the guard's utensils. Manpower is precious, and Chen Shouxu did not equip himself with special servants.

"Have you sorted out the means to prevent malaria?" Chen Shouxu also poured himself a cup of tea.

In Jincheng's health regulations, the prevention and treatment of malaria is the most important of the priorities. At this time, there are only two drugs that can be determined to have an effect on malaria: Artemisia annua and cinchona. The fleet captured several Spanish cities in South America and has stockpiled some cinchona bark ever since. But relying on reserves is certainly not a long-term solution.

Now it is certainly impossible to extract artemisinin from Artemisia annua, so we can only use the ancient Chinese recipe "Artemisia annua one hand, two liters of water to soak, wringing juice, and taking it." "From the perspective of modern medicine, the active ingredient exuded by the stranded Artemisia annua is definitely not enough for the therapeutic dose. But for ordinary people at this time, continuous medication will also play a role. Until you can provide enough cinchona bark, it is better to drink Artemisia annua juice than to lie in bed and wait for death.

The so-called dispute between Artemisia annua and Artemisia annua is just a misunderstanding in the translation of botanical names in later generations. There are many examples of Artemisia annua in Chinese medicine, all of which refer to the botanically named Artemisia annua. In Li Shizhen's Compendium of Materia Medica, in addition to Artemisia annua, Artemisia annua is also recorded. But the yellow artemisia he recorded was not Artemisia annua for malaria, it was a different plant. The Artemisia annua described by Li Shizhen is not the same as the medicinal Artemisia annua under the later botanical name. Traditional Chinese medicine has never missed a medicine that can treat malaria.

In addition to cinchona bark and artemisia annua, Jincheng also collected some strange recipes, such as wrapping the dough in peppercorns and swallowing, soaking garlic in wine for seven days, and drinking it when the disease occurs. Whether it's useful or not, let's talk about it after using it, it's harmless after all, and it's better than waiting for death.

Giovanni. "Since it has been determined that the cause of malaria is mosquitoes, our main means of control is to kill mosquitoes," Tornatore said. Giovanni didn't know why the problem was mosquitoes, but Chen Shouxu said yes, that is. And Giovanni recalls that the areas where malaria is most prevalent are generally moist and low-lying areas near the sea.

He had also recently noticed that in areas mixed with saltwater and freshwater, mosquito larvae were significantly more abundant than in pure freshwater. However, regardless of whether it can be understood or not, the work that the top leader personally grasps must be fully promoted.

Chen Shouxu emphasized: "Dean Tornatore, malaria is a disease that people advance and retreat, you see that many places in history are areas where miasma diseases are prevalent, and after continuous development by human beings, malaria has gradually decreased. It is no accident that the transformation of the environment by human beings, as well as the raising of poultry and livestock, can gradually reduce the incidence of malaria. ”

Giovanni took out a few pieces of paper from his bag and handed them to Chen Shouxu, "Yes, my lord, we understand your point of view. Based on the existing conditions, we have compiled some preliminary measures for adults to take a look at. ”

The first is to ensure the cleanliness of the urban environment, and the establishment of an urban sanitation management office under the jurisdiction of the Health Bureau is responsible for the sanitation management in the city. Considering the current quality of the population, in addition to cleaning personnel, it is necessary for the urban management office to be equipped with a certain amount of armament.

Chen Shouxu agreed, "Chengguan should be a powerful department. Tomorrow I will give you a few of the most capable sailors in the fleet, and it makes sense to say that for those who litter and defecate at will, they must fight. But your suggestion is not atmospheric, I'm going to change the name. Urban Management Office, where did you put the countryside? I think it's better to call it the Urban and Rural Health Management Office. ”

Giovanni was initially happy, but after thinking about it carefully, he felt that it was inappropriate, "We don't have enough people to manage the countryside." ”

Chen Shouxu took a sip of tea and said indifferently: "Can you add people slowly?" If we don't extend the scope of management to the countryside, how can we get rid of mosquitoes? I know your concerns, but for the time being, you just need to take care of the health of Jincheng and the surrounding army. ”

"Yes, sir."

Chen Shouxu then looked at it, and then the specific implementation plan, which is divided into 9 main points:

1. Specifically divide the cleaning area and implement one street sweeping a day;

2. Keep the residents' water tank clean and drink new water every day;

3. The utensils and furniture should be placed in a certain place, not messy, and should be kept clean frequently;

4. Organize the work of mosquito and fly control;

5. Don't drink raw water, don't eat raw cold;

6. Wash clothes frequently, wash hands frequently, and wash and dry quilts frequently;

7. It is forbidden to dump garbage in the river;

8. It is forbidden to pile up dung heaps and garbage in the city;

9. The sick and healthy people should be isolated.

Chen Shouxu finished reading, "It's good, I'll add two points." ”

Giovanni hurriedly took out his notebook to record.

"Rural toilets and pigsty should be absolutely separated, and kitchens must not be co-located with toilets." Since taking office, Chen Shouxu has visited the countryside several times, and he was deeply impressed by the environment of the toilets. "The toilet should be disinfected with lime regularly, and it is best to dig deep and have a smaller mouth, otherwise when it rains, the effect will be simple."

"Yes, sir."

"Organize people to go to the streets every day, and the area is divided into sections, and the puddles must be eliminated in time. All the drainage ditches in the city were converted into culverts, and stone covers were added. ”

Giovanni looked embarrassed, "My lord, this is too demanding on manpower. ”

Chen Shouxu didn't give him a chance to back down: "The highway is almost finished, I will draw someone to you." You just have to do your job well, and if you have any difficulties, come directly to me. ”

Giovanni: "That...... Alright then, sir. ”

Chen Shouxu looked at the hospital director with a tired look, and he couldn't bear it, Giovanni was the busiest person in the city during this time. "It's okay, just go back and rest. I'll look for Lynch to get a few ginsengs, which a Chinese businessman gave me the other day. I don't need it, you can take it back and use it. ”

After learning from traditional Chinese medicine, Giovanni now knows that ginseng is a tonic medicine in traditional Chinese medicine, but he is still very skeptical about the actual effect, so he just took it and tried it.

After sending off the director of health, Chen Shouxu opened the steel industry plan sent to him by the Department of Industry. Chen Shouxu didn't have the energy to manage light industry, and that was the business of the Department of Industry itself. Chen Shouxu only focused on the iron and steel industry, which is the cornerstone of the arms industry.

Steel is the backbone of the country and its people, and a country with a low level of steel per capita must be a failed country. Even in agriculture, if farmers had sufficient and cheap iron tools and a variety of iron products at their fingertips, the yield of agriculture would increase greatly.

Jincheng has ample reserves of timber resources, and there are tin mines in the mountainous areas of the south, but there are no iron mines in the territory. Of course, there will be no large-scale steel industry in Jincheng now, but given the importance of steel, Chen Shouxu needs to make technical reserves now.

Under the existing conditions, no one is capable of rewriting the history of human metallurgy. Those who vainly try to rely on their personal ability to build a few earthen blast furnaces in ancient times can make the ancient craftsmen bow their heads to nonsense. The slightest progress in the history of metallurgy is the achievement of hundreds of engineers and craftsmen leading thousands of workers to spend countless hours exploring, experimenting, and repeating. And often a breakthrough in a small link can simultaneously drive the progress of other details. After 2,000 years of continuous mutual promotion, mankind entered the age of great industry.

Chen Shouxu didn't have a delusion that he could refine liquid steel now, and he didn't dare to think about crucible steel. It is no coincidence that liquid steel appeared after the steam engine. Without a high-horsepower blower, it is not realistic to refine liquid molten steel only by relying on the modification of the regenerator, manpower hydraulic blower, and furnace air duct. Even in a certain period of earth-based steelmaking, an electric blower was required in the initial phase of the plan.

What Jincheng Industry needs now is to completely replicate the existing steel smelting technology in Europe, and then it can talk about development and progress.

There are a few blacksmiths in the fleet and people in the research institute who can reproduce the existing blast furnaces in Europe.

Chen Shouxu opened their scheme, which can be roughly divided into British and German. At this time, Britain had block smelting furnaces for the direct production of wrought iron and blast furnaces for the production of pig iron, while Germany had more blast furnace body block smelting furnaces than the United Kingdom. He carefully looked at the difference between the entire technical route of the two schemes.

Regardless of the route, hydraulic blowers are used, and charcoal is used as fuel for smelting.

For Chen Shouxu, these two items are not difficult to satisfy. The most indispensable thing in Southeast Asia is about water, Jincheng is a place with an annual rainfall of more than 2,000mm, and there are many rivers in the territory.

There will be various problems in coal iron making, coking is not an easy thing, Chen Shouxu does not have a stable source of coal, and Jincheng is not short of wood, and charcoal is just right. For the time being, he crossed out the tech tree for coal and iron.

Hydraulic blowers are no problem either. Here, however, the European craftsmen of Jincheng unanimously abandoned the accordion-style leather blower in favor of the Chinese piston bellows. China uses hollowed-out trunks of large trees to make piston cylinders, which are superior to leather.

Blast furnace ironmaking, there is no technical difficulty. Germany uses more low furnace belly blast furnaces, and Britain uses high and steep furnace belly blast furnaces.

Then there is the blast furnace block refining furnace. Wrought iron can be obtained by forging pig iron, and in theory there is no longer a need for a block furnace. But since all countries are still using block refining furnaces, there are also merits in the natural economy.

Wrought iron blowing furnaces still have some remnants in Britain and Spain, Chen Shouxu thought about it and built it. At the stage of technical reserves, he did not dare to skip every step of the history of metallurgy.

This is followed by a refining furnace for the production of wrought iron. The German route used an open furnace, and the entire refining process was forged. The UK uses two open furnaces, the first of which is a refining furnace for decarbonization. The second furnace is used to store reheated iron for forging, and is called a forging furnace. Chen Shouxu carefully chose the British route, and he simply believed that two furnaces were better than one.

Hydraulic blowers are still used in refining furnaces. In the process of refining, forging is also required. Therefore, it is also equipped with a forging hammer and a hydraulic hammer for foot pedals. At this time, it was difficult for the forging hammer to forge more than 100 kilograms of iron billets, but Chen Shouxu's most direct demand for wrought iron was to make gun barrels and swords, so it was not much of a problem for the time being.

This is followed by a cutting machine and a rolling mill. The application of cutting machines has been more in Europe, and the problem is mainly disc cutters. The rolling mill is not widely used in Europe, and Jincheng still needs to be studied.

With wrought iron, you can get steel. Until the furnace temperature reaches 1600 degrees Celsius with refractory materials and high-horsepower blowers, liquid molten steel is not available. The only way to get steel is carburizing or lump smelting. Even in Europe, it is now difficult to get steel. Europe's iron used to make steel is highly dependent on high-quality iron ore from Sweden. Around Chen Shouxu, there is only one high-quality iron mine that can be obtained, and of course he can't afford to occupy and develop it now.

Carburizing and block refining are traditional crafts in the East and the West, and what Jincheng can do is to find a production method that meets its own conditions and has the lowest cost on the basis of traditional craftsmanship.

The Department of Industry also reported on the improvement proposal submitted by a brain-screwing craftsman. The cast iron smashed into small pieces is melted in a block furnace, and the smashed wrought iron pieces are thrown into the furnace and kept under the lime slag for several hours, the whole process must be kept at a high temperature. Chen Shouxu roughly understands that this is to let wrought iron absorb the carbon in pig iron. Then take out the iron block, quench it, smash it, and then put it back in and melt it again. Is this repetitive carburizing? Chen Shouxu didn't know, and he didn't dare to refuse.

After he finished reading the planning of the entire steel technology route, he could only curse secretly, he was another gold-swallowing beast.
