There are a large number of documents on the table, basically all of which are related to the development and manufacture of firearms, which are all top secrets today, but Xu Wanghua still managed to get them, because Zheng Xunrui wanted to see these materials.

Xu Wanghua understood that Zheng Xunrui was thinking about developing firearms, and they were firearms that needed to be improved, but he didn't know what Zheng Xunrui needed these materials for, after all, making firearms was a craftsman's business, and Zheng Xunrui couldn't do it himself, so it should be useless to look at these materials.

Zheng Jiajun won a major victory in the Battle of Yongning, captured the Wuying County King Azig of Houjin alive, killed more than 10,000 Houjin Tartars before and after, and Zheng Xunrui was enshrined as the crown prince Shaobao's mansion also arrived at the Huai'an Governor's Palace, these things have spread throughout Huai'an, and the impact is great, especially some scholars and merchants in Huaibei have abandoned the previous Qing Gao and arrogant, and began to take the initiative to contact the Caoyun Governor's Mansion and local officials.

Nearly two months have passed, Huai'an is calm, nothing noteworthy has happened, Xu Wanghua, who presided over the affairs of the Caoyun Governor's Palace, also seems relatively relaxed, his main energy is still concentrated in Hongmen, this is the task ordered by Zheng Xunrui before leaving, it is necessary to expand the power of Hongmen, so that Hongmen has a pivotal role in Huaibei and Caoyun things, if you want to achieve this goal, it is necessary to increase the children of Hongmen, especially those who have the ability to enter Hongmen.

has been with Zheng Xunrui for a long time, and discussed a lot of important things, Xu Wanghua faintly understood that Hongmen would become an important force for Zheng Xunrui, and many things that the Caoyun Governor's Mansion and the local government did not come forward to do, probably let Hongmen do it, to a certain extent, Hongmen's influence even exceeded that of the local government.

Zheng Xunrui is looking at the documents carefully, these documents are ugly, most of them are about the theory of firearms manufacturing, Zheng Xunrui has no special research on this, and now he regrets it and has no way. It is impossible for me to know that I will be able to cross, or I should study the military knowledge of firearms and artillery, etc., and with this knowledge to cross, I can now play a major role.

The traversable Zheng Xunrui. It's not that he doesn't know anything about firearms and artillery, but without going to a specific environment, it is impossible for him to think of these things, and he asked Xu Wanghua to find these documents. Perhaps, in the process of learning, you can think of some key points, and put forward some key suggestions when you start manufacturing firearms or artillery in the next step, so that the pace of development of firearms and artillery can surpass the times.

This is not an impossible thing, many times scientific knowledge is often inspired in a moment, for example, the law of gravitation, isn't it Newton who saw an apple fall on the ground and had a question, and then discovered the law of gravitation.

February 10. Zheng Xunrui returned to Huai'an.

After a good day with his family, Zheng Xunrui experienced a lot of happiness.

Zheng Hanyu has been taught by Wen Manshan and began to learn poetry, although he is not yet three years old, he can also recite a few Tang poems and Song lyrics, Zheng Lingrui and Zheng Lingrou are beginning to learn to walk, Zheng Linglan is also struggling to walk, but unfortunately she is younger than her two sisters, and she is still unstable and unable to learn to walk.

Wen Manshan told Zheng Xunrui. She also wants to give birth to a daughter, seeing Zheng Lingrui, Zheng Lingrou and Zheng Linglan, Wen Manshan must have an idea in her heart, and they all say that her daughter is the intimate little padded jacket of her parents. Although it is true that in this era, the social status of women is not good, but it also depends on what kind of family they are born in, and his daughter Zheng Xunrui will not be able to suffer in the future.

The notion of more children and more blessings is dominant, not to mention the present. Even after hundreds of years, since Wen Manshan wants to give birth to a daughter, then Dongmei, Lotus Ye, Yang Aizhen and others are afraid that they also want to have a son.

Thinking of these, Zheng Xunrui has a headache, there are too many sons and daughters, and it is also a headache.

After spending a day with his family, Zheng Xunrui began to act in government affairs.

From the first Cao Yun this year, there is less than a month to go, the 500,000 stone grain that needs to be transported has long been prepared, of course, this time the situation is a little special, Zheng Xunrui also needs a lot of grain, Shaanxi, Fuzhou and Penglai and other places are in need of food, there must be food to be able to stabilize these places, especially Fuzhou and other places, have just been recovered, and the people who have been exploited by the Golden Tartars for a long time have almost no grain at home, and must rely on the relief of the government to be able to survive this few months of green and yellow life.

All the grain is stored in the granary, and the storage capacity has reached 800,000 stones, of which 300,000 stone of grain will be transported to Shaanxi, Penglai and Fuzhou and other places by water or sea.

It has been several months since the rectification of Caoyun, and Li Cao's participation in politics Shi Kefa, the supervision and urging of Ma Shiying, and the escort of Su Jiancheng to participate in politics have long been deeply involved in it, familiar with the matters under their respective jurisdictions, and with the strong support of the Huaibei local government, there is no big problem in all the preparations for Caoyun this time.

The development of Hongmen is also very rapid, the former Shanyin gang leader Xu Jikuang, after taking refuge in Zheng Xunrui, did his best, not only to assist Xu Wanghua and Wen Kun, but also to vigorously help the owner of Hongmen Gate Hong Mingcheng, so that Hongmen can develop rapidly in a short period of time, and the internal management is basically standardized.

Hongmen is not an official government, it is impossible to manage it completely in accordance with the set of the government, and its management mechanism and system must have the flavor of the rivers and lakes.

Back in Huai'an, Zheng Xunrui found that everything was going very smoothly, and he was very happy, so that he could devote himself to the affairs of the Firearms Bureau.

Rubbing his eyes and raising his head, Zheng Xunrui found that Xu Wanghua was a little dazed.

"Mr. Xu, haven't you read these documents?"

"My subordinates haven't read it, and to be honest, my subordinates can't understand these documents, and my subordinates don't understand what some of these strange symbols mean."

Zheng Xunrui smiled, Xu Wanghua was telling the truth, the development of firearms involves the knowledge of mathematics, physics and chemistry, which has been valued in the West, but in the Ming Dynasty, more than 99% of the people do not know what physics and chemistry are, and missionaries like John Tang are still very familiar with the relevant physics and chemistry knowledge, including mathematical knowledge.

"Mr. Xu, if you don't understand it, you have to see it, the development of this firearm is very important, if you can't understand the truth, it is difficult to control the direction of development, for example, I want to develop a more advanced flintlock pistol, I have to think of a general direction of improvement, a few days ago you have also seen the flintlock pistol developed by Lord Bi Maokang, even if it is a brave soldier in the Zheng family's army, it is very difficult to pull the trigger, we have done experiments, the cavalry launched an impact five hundred meters away, the flintlock pistol can pull the trigger up to three times, Coupled with the time it takes to pour gunpowder, it is difficult to fire three times, and with such efficiency, it has no effect on cavalry. ”

"After reading the paperwork for most of the day, I thought of a possibility, that is, whether the flintlock pistol can be fired more than five times within the time of the five-hundred-meter charge, which can form a real kill, and I also considered a question, that is, whether the front of the flintlock pistol can be equipped with something such as a short knife, even if the cavalry or foot pawn charges up, the sergeant with the flintlock pistol can also fight." ……

While Zheng Xunrui was still speaking, Xu Wanghua's face changed.

After Zheng Xunrui finished speaking, Xu Wanghua's face was slightly red and he spoke.

"The adult is really far-sighted, read these documents, you can put forward so many suggestions, subordinates are absolutely impossible, just heard what the adult said, the subordinates immediately thought of the long-handled eyebrow knife, the adult proposed to install the blade in front of the flintlock pistol, it is completely feasible, the length of the flintlock pistol is one meter away, the length of the blade is about sixty centimeters, which is not much different from the long-handled eyebrow knife, and the power is far stronger than the long-handled eyebrow knife, such a novel idea, the adult can think of it, the subordinates admire it."

Zheng Xunrui pretended to be calm, he was a person who crossed over, and it was just a piece of cake to put forward these ideas, and in the process of reading the paperwork, he also thought of some ideas, or reminders, but these ideas had to be said to Bi Maokang, Tang Ruowang, Bo Yu and others to be useful.

It is common sense that the gun is equipped with a bayonet, and the bayonet can be removed, so as not to affect the accuracy when firing due to the increase in weight, and once the bayonet is installed, it means that hand-to-hand combat begins.

Of course, Zheng Xunrui will not say these truths.

As for the development of firearms, it is still necessary for Tang Ruowang, Bo Yu and others to be transferred to the Caoyun Governor's Mansion before they can start preparations, and there is a very key link in this, that is, Yang Tingshu was transferred to Nanzhili to serve as the head of the household department, and you must know that the firearms bureau is directly under the jurisdiction of the head of the household department.

The secretary of the Nanjing military department is the highest administrator of the Nanzhili, responsible for all matters, focusing on the control of the Nanjing Beijing camp, as for the firearms bureau such a place, the military department is not so detailed, so it is under the control of the household department Shangshu, which is different from the capital, the firearms bureau in the capital is directly under the jurisdiction of the military department.

What Zheng Xunrui needs to do now is to wait, he believes that Tang Ruowang and Bo Yu and others come to Huai'an, there is not much of a problem, especially Bo Yu, but he is the deputy envoy of the military department from the ninth grade, no one pays attention to it at all, the more difficult thing is Yang Tingshu, if you want to serve as the secretary of the household department in Nanjing, there may be a certain process, but this is not a particularly difficult thing, although the Yin of Shuntian Mansion is only the grade of the third grade, but in terms of the importance of the position and the future, it is far stronger than the secretary of the household department in Nanjing, Yang Tingshu served as the secretary of the household department, It would be considered exclusion.
