As the kings subsided, three families were killed and four families were expelled from the country, the court finally quieted down again, and the time quietly came to September and autumn.

Seeing that the strategy of "resting with the people in spring and summer, and taking advantage of the cool and cool south in autumn and winter to train troops in small-scale rotations and sweep away hidden dangers in the rear" set last year, it is time to attack again.

Zhu Shuren, who had rested enough, came to Jiangning Town again, inspecting the work and taking stock of new scientific and technological discoveries, holding a meeting to sum up the lessons and lessons of last year's land reform and return, and at the same time checking and filling in the gaps for the upcoming work of recovering the big people, and sharpening the guns on the spot.

The second year of Longwu seems to pass very quickly, giving people the illusion that "it seems that the golden autumn of September of the previous year has only passed three or four chapters, why is it the season again".

But there is no way, who let everything this year be based on consolidation and recuperation, and politically can not toss without tossing. The Qing court in the north was also recovering its army's combat effectiveness and licking the wounds of the previous year.

Everyone is safe, and there is no need to repeat everything.

Zhu Shuren is happy to put most of his energy on his wife and children, and his life passes very quickly-

Every middle-aged man who has just had a baby will feel this way at this stage. It seems that every day is so busy that I don't have time to turn my brain, and I am pushed away by all kinds of unexpected things, and the lake has passed again.

And when he reaches the rank of Zhu Shuren, even if he is recuperating and taking care of a baby at home, he can always contribute more or less to the society.

No, for example, at the end of last year, he made a lot of small progress in obstetrics and gynecology medicine in order for his wife to have a smooth delivery.

If any small improvement can be promoted, within the scope of the overall Ming Dynasty, at least it will be a benevolent act that kills tens of millions of pregnant women and babies every year.

The only danger is that it may lead to a rapid increase in population growth in advance, and after decades of chaos to reduce the pressure, the population will be reduced by more than half, and it may be possible to enter the Malthusian trap high-speed lane again.

But that's all for later, so I don't have to worry about it in the short term. The fame and popular support that the promotion of medical progress has brought to Zhu Shuren is real.

After the conspiracy of the kings was exposed, the people of Nanzhili and Zhejiang, Jiangxi generally resolutely supported Zhu Shuren, which was more or less related to the birth of Zhu Shuren's son and a lot of medical and health progress to benefit the people.

After all, the birth of this child is accompanied by a bunch of things that are silent and beneficial to the people, and the people of the world also have rods and scales in their hearts.

Previously, so many fat vassal kings in the Ming Dynasty had bred for so many generations, and they would only scavenge the people's fat and people's cream, but they had never seen that vassal king get a son and could really benefit the common people.

In order for the son to be born smoothly, so many medical advances must be deployed, and there is more work to be done in the follow-up to ensure the smooth and healthy growth of the baby.

In ancient times, the mortality rate of infants and children was not ordinarily high, and the safe birth of children could only be regarded as the first hurdle.

If other emperors were on the throne in previous years, the prince was not valuable, as long as he could give birth to the first one, he could give birth to the second and third, and it didn't matter whether he ensured that the concubine was born or whether he was born to the queen. Then I don't care if the level of medicine is upgraded, and I will be reborn after death.

Zhu Shuren's situation is very special, his son wants to succeed to his brother-in-law who is nominally dead, which is not easy, and he has to toss a lot of bad things about the court's legal principles and etiquette.

And his son must be born to his wife, so there is a possibility of succession, and his wife's birth is somewhat hurtful, who knows if she can give birth to a healthier child in the future. In this respect, it is completely different from those emperors who rely on the pure ascendancy of the patrilineal lineage itself.

Therefore, in order to ensure that children do not die young, it is worth spending more energy to improve the level of children's medical care.

is still the same sentence, how much money did Chen Ajiao spend on Liu Che back then, and Zhu Shuren left at least ten times more budget, which is a national issue.

(Note: In the previous chapter, someone actually questioned Chen Ajiao in a private message for spending 90 million to see infertility, saying that it was a wild history.) Let's post the original text: "Queen Chen has no children, and she has 90 million yuan for medical money, but she has no children" - "Historical Records. The Family of Relatives", Sima Qian)

So from moving the palace in June to connecting the kings in September, in the middle four months, Zhu Shuren also arranged a few idle chess, all about children's medical and health care.

In Jiangning Town, a southwestern suburb of Nanjing, there were already several research institutes last year, namely agriculture and animal husbandry, naturalism, physics, mechanical, metallurgy, etc., and this year on the basis of the original agriculture and animal husbandry naturalism, a medical research institute and a pharmaceutical research institute were added.

The initial investment of each building is at least tens of thousands of taels, and the total amount of subsequent continuous funding may reach two or three hundred thousand taels.

Zhu Shuren is a modern person, and he doesn't understand ancient medicine, so he can't interfere in the part of traditional Chinese medicine, but just allocate some money to provide a platform for some high-level imperial doctors and prestigious folk doctors.

What he can do is mainly to improve the upgrading of surgery in this era, especially the upgrading of trauma management, infection prevention and other subjects. There is also a summary of research on the principles of the spread of various plagues and their prevention and control.

Because as a modern person, even if he doesn't understand medicine at all, the common sense of surgical trauma treatment is far better than that of the ancients, who did not know bacteria and viruses, nor did they know the principle of infection.

Epidemiology is also a common advantage of modern people, the ancients did not know the existence of bacteria and viruses, so it is difficult to comprehensively summarize the transmission principle of various bacteria and viruses. Modern people will always encounter various epidemics of infectious diseases, and they also know the common sense of hygiene.

For children's medical care, trauma management and infectious disease prevention and treatment are also more important. Because children are ignorant and naughty, they are easy to bump and be injured, and they also like to touch flowers and grass and touch with infectious agents.

After the hygienic means of trauma treatment and plague prevention and control are upgraded, it will also be of great help to military doctors in wartime in the future, and can save more brave wounded soldiers of the Ming Dynasty.

In addition, there is another convenience in setting up a medical research institute in Jiangning Town, which Zhu Shuren only discovered after starting - last year he had built the first zoo and botanical garden open to the public in Jiangning Town, and with that botanical garden as the foundation, he requisitioned land to open up an adjacent new park, which can be used for the cultivation and exhibition demonstration of herbal plants.

Although more than 40 years before Zhu Shuren, Li Shizhen had already written the "Compendium of Materia Medica", and now the Ming Dynasty has also printed and published, and the "Compendium of Materia Medica" also has pictures.

However, the number of pictures in the "Compendium of Materia Medica" cannot be given to every herb after all, Li Shizhen was a private writer back then, and he did not have the conditions and cost to produce such a luxurious book.

What's more, even if all the pictures are there, the intuitiveness gap between reading the book and the real thing is still very large, and it is easy for readers to joke that "they recognize grass according to the pictures and recognize wheat as leeks".

Now, after the new herbal medicine garden is built in the botanical garden, we will strive to leave a small piece of physical cultivation demonstration of all the herbs that can be cultivated and cultivated in the south of the Yangtze River, and leave a little complete specimen, which can be used by doctors and pharmacy apprentices all over the world to observe and learn errata and reduce quacks, which can be regarded as immeasurable merit.

If the climate is not suitable for planting and display, if it can be solved by mica skylight greenhouse, try to solve it, so that tropical herbal plants can also be displayed.

Only cold-tolerant herbs such as ginseng remain, and Jiangnan really can't grow them, so after the Central Plains is recovered, they will rebuild a botanical garden in the cold land of the north.

All these displays, Zhu Shuren is also in accordance with the norms of modern botanical and botanical gardens and museums, each flower and tree is inserted in front of a small painted wood sign, written with the name of the species, the habit of origin, no need for a narrator to understand.

In addition, not all ancient medical drugs are plant products, and there are many animals used in medicine.

For those animal medicines, Zhu Shuren also opened a new expansion park in Jiangning Zoo, displaying live medicinal animals, some fresh and dried specimens, and individual specimens of medicinal organs for doctors all over the world to learn. The same goes for zoos, and each building has a wooden sign with an explanation.

As long as you can prove that you are practicing medicine or studying medicine, as long as you can afford the travel expenses and accommodation to come to Nanjing, you can visit for free, and there is no admission fee. Other people can also visit, but they will have to pay a reservation and limit the number of people per day.

All of a sudden, in the summer of the second year of Longwu, there were not many people and apprentices who practiced medicine in Nanzhili who came to Nanjing to worship and visit.

After these people visit, they will naturally further promote the virtue and politics of the prince of E, and they will also support and empathize with the matter of going to the step-grandson and moving the palace today.

Everyone said that today's Sun is God's blessing to the Ming Dynasty, the whole world celebrates, and Ze and all the people.

……

"I haven't been here for a few months, and there have been a lot of changes in this Jiangning town, and it seems that the silver has not been smashed in vain."

One day in mid-September, when Zhu Shuren arrived in Jiangning Town again, he first walked around and looked around, and then prepared to find another industry to stay. What he saw and heard made him very satisfied with the results of his money on farming.

"They are all the kings, the rulers and the people, the students look at the annals of history, and the benevolent rulers of ancient and modern times all regard the construction of the land as a labor and a loss of money. There is no one who can be like the prince, but the construction of a large number of projects will benefit the people and will not cause the disadvantages of Emperor Qin and Sui Yang. ”

Gu Yanwu, Zhu Shuren's secretary, also praised it from the bottom of his heart. He reads a lot, and he sees a lot of simple and benevolent monarchs who rest with the people, and he also sees a lot of emperors who are so happy.

But it is unheard of for a ruler who does not add too much burden to the people and whose input-output ratio is obviously more profitable.

Zhu Shuren was used to this kind of honest touting, so he just smiled: "Don't talk about this, has Brother Zheng Xian arrived?" ”

Gu Yanwu carefully reminded: "Lord Wang, you and Zheng Langzhong have an appointment the day after tomorrow, September 15, and we are here early." He came from Fujian, and he had a fixed journey on the way. Especially a few days ago, I heard that the Zheng family was still helping to thoroughly investigate the clans that had established and moved the feudal clan in Fujian, and the incident was sudden, which made it even more urgent. ”

The kings have only turned the page for more than ten days, and at that time, not only Zhejiang and Jiangxi were conducting a thorough investigation, but Fujian naturally had to cooperate. It's just that there are very few vassal kings who have gone to Fujian since ancient times, so the workload is smaller.

However, there are also some former members of the clan who have already been deposed from the throne, who may live in Fujian, and the Zheng family has also checked more in order to curry favor with the ruling Zhu Shuren.

For example, Zhu Yujian, the deposed Tang Dynasty king who was supported by the Zheng family as the "Emperor Longwu" in Fuzhou in history, still lives in Fuzhou because of historical inertia.

It's just that unlike what many people think, this Zhu Yujian was abolished by Chongzhen at the end of the Chongzhen Dynasty because of the crime of "mercenary self-respect", and it has been abolished for seven or eight years. In history, when Zhu Yousong and Zhu Changshu were in power for a short time, they did not restore him to the title. In the end, Zhu Yujian was completely in a state of abolition and was directly supported by Zheng Zhilong and Huang Daozhou.

Now that history has changed so badly, Zhu Changshu became the emperor as soon as he came up, and of course he did not restore Zhu Yujian to the king. This time, it didn't affect him. After the Zheng family snooped around, they confirmed that they had not found any clues that Zhu Yujian had contacted the kings of the Eucalyptus, and Zheng Chenggong didn't want to frame the good guys, so he was ready to play truthfully.

Speaking of which, this Zhu Yujian can be regarded as a blessing in disguise, but as long as he was restored to the prince before, he may be contacted by other princes, and he will have to be imprisoned for life at that time. Although he didn't recover his knighthood in the first place, he can live freely for the rest of his life.

Zhu Yujian is still a very backbone, down-to-earth, and effective Ming Dynasty vassal king in history, and he can completely stay out of the matter in advance, which is also what Zhu Shuren is happy to see.

After learning about the Zheng family's recent actions, Zhu Shuren also expressed his gratification: "Brother Zheng Xian is willing to seek truth from facts, which is a good thing. Since we are early, we naturally will not be harsh on him.

Lone's original intention was that he hadn't come for a few months, so he would come to Jiangning to have some fun first, and in the past two days, you have inquired about it, and when Brother Zheng Xian arrived, he immediately brought him to see me.

Last year, Li Dingguo changed the land and returned to Yungui and returned to Yungui, and he still gained a lot of experience in using troops, and the Fujian side should also learn the usage and prevention of some tropical disease prevention and control drugs to prevent problems before they occur. Miasma fever on Dayuan Island will only be worse than in Yunnan. Let the medical officers under him have a good exchange with the medical officers sent back by Li Dingguo. ”

Gu Yanwu immediately said that he had received instructions, and he would keep an eye on everything, and he would summon Zheng Chenggong as soon as he arrived.

Zhu Shuren: "Then while Brother Zheng Xian has not yet arrived, let's arrange for Gu to inspect all the research institutes in the next two days." This year, I think they have also made a lot of achievements. ”

Gu Yanwu immediately arranged it, and starting at noon that day, Zhu Shuren temporarily inserted some itineraries, taking turns to visit various research institutes in Jiangning Town, as well as the iron and steel mills, copper smelters, and arsenals in Ma'anshan.

The most important thing in this is, of course, the arsenal, so I was in line first in the afternoon of the first day.

Zhu Shuren looked very carefully, and found that the technology of magnetic beneficiation has improved, and after more than a year of running-in experiments, the craftsmen and mining beneficiaries of the steelmaking plant have also trained a lot, and they can master some new technologies.

The steel output and quality of Ma'anshan Iron and Steel Plant have also increased again.

At the same time as the availability of higher-quality steel, weapon forging and processing technology has not been idle. When Zhu Shuren inspected last year, he saw that the craftsmen could only pull out rifled guns. Now, after another year of trial and running-in, I can finally pull out a more evenly rotating spiral rifling.

The moment he saw the spiral rifling gun, Zhu Shuren was naturally surprised, he knew too well the significance of this thing for long-range sniping, and hurriedly asked about the effect of the live-fire test.

】

But he soon learned that there were still big problems with the spiral rifling that had just been put on, first of all, the process of loading ammunition in the breech had become slower, more complex and finer, and the reliability and environmental compatibility had also decreased.

However, when the climate changes greatly, or there is rain, snow or sand and dust entering the chamber of the gun, it is also much more difficult for the spiral rifling to clean up foreign objects.

Even if there were no accidents, the rate of fire of the original spiral-rifled muskets had to be further reduced from the original rifled guns of two to three minutes to four minutes.

In fact, in an environment with a little more sand and dust, or in the case of low gunpowder combustion sufficiency, this new gun cannot be reloaded on the battlefield at all, and can only be loaded with one shot before the start of the war, and after the battle, it will become a burning stick -

Of course, with the spiral rifling, even this first shot, the power and accuracy have been greatly improved, and basically you can accurately shoot at targets within three or four hundred steps, as long as you are equipped with a sufficiently elite sniper, you can aim accurately, have good eyesight, and good marksmanship.

In order to achieve reliable reloading in complex battlefield environments, there are still many new running-in fine-tuning improvements to be made.

In addition, the first generation of spiral rifling guns, there is a big problem, which has just been discovered in the research and development, that is, the probability of the musket blowing up the rifle has been greatly increased compared with the original rifled gun, since last month, there have been two explosion accidents, the reason is still being analyzed, and the craftsmen are even considering whether it is necessary to further thicken the barrel to solve it.

They just don't understand that the same thickness of the barrel wall and the same rifling groove depth have the same effect on the strength of the barrel, so why is it especially easy to explode after changing to spiral rifling?

If the craftsmen were to figure it out for themselves, it would take a long time. Fortunately, Zhu Shuren knew more about physics than them, and he also watched and listened very carefully during the inspection, and after observing a few live firings, Zhu Shuren thought about it again.

Zhu Shuren casually dialed: "It should be the reason why the spiral entanglement of the rifling wire is always given, right?" When the gunpowder is just ignited, the chamber pressure is the largest, so if the rifling entanglement at the end of the barrel is relatively large and the inclination rate is high, the torsional moment of the projectile being pressed into the rifling will also be very large, and the barrel can not withstand this force, which will increase the probability of exploding.

After the projectile flew forward a few feet in the barrel, the chamber pressure had dropped significantly, and the moment in the direction of rotation was a little larger, and the barrel could also eat.

So, two ideas to solve, either the rear of the barrel is thickened. Either when rifling, the rotation rate should not be fixed from beginning to end, it can be straighter when it is close to the tail of the barrel, and the closer to the muzzle, the higher the spiral inclination. In short, it is from a fixed entanglement to a gradient entanglement that is tilted and intensified, and you can try it slowly, and you can say it casually. ”

The solution he said wasn't necessarily right, and maybe there were some variables that were missing in principle. But the experimental idea is no problem, and there is nothing wrong with introducing the idea of variable slope of the entanglement to inspire craftsmen to try a few more times and accumulate more experience and experimental data.

Zhu Shuren's only requirement is that all experiments that have spent money must record the experimental process, results, and data, even if they fail, they should summarize the lessons comprehensively and let future generations know why, even if the money was not spent in vain.
