Bi Maokang is the right waiter of the Nanjing Ministry of Rites, a high-ranking official of the three grades, although there is nothing to do in Nanjing, but a leisurely life is still possible, to Nanjing Liubu and the Imperial Court of the Imperial Palace, the squire, the left and right imperial history and the left and right deputy imperial envoys, either in the capital encountered exclusion, to Nanjing to leisure, or is old, here to wait for the rest, there are also some who take the initiative to ask to come to Nanjing, such as the deceased Nanjing Ministry of Rites Shangshu Dong Qichang.

Bi Maokang was obsessed with the development of firearms, he was a Jinshi in the twenty-sixth year of Wanli, and successively served as a scholar in the middle school, supervising the imperial history, the imperial history of the right capital, and the governor of Yunxi, and later transferred to the right attendant of the Nanjing Ministry of Rites. It did not have much achievements in politics, but in the research and development of firearms, it was a top expert, Chongzhen eight years, Bi Maokang's book "Illustrated Weapons of Weapons" was written, which was about the production of flintlock pistols and principles, and the first flintlock pistol was also manufactured in this year.

It is a pity that the manufacture of firearms has not been paid attention to by the imperial court, and is regarded as a three-religion and nine-rate business, when Xu Guangqi introduced the Hongyi cannon, it was still carried out under the premise that the imperial court did not allow it and paid out of his own pocket.

The Hongyi cannon and the Francophone showed their power in the battle, and then the imperial court took out the silver and bought more Hongyi cannons.

However, there are deep-seated reasons why firearms have not been taken seriously, and it cannot be said that all the people in the DPRK and China are short-sighted, and this is also because of the many problems and limitations of firearms themselves, for example, the bird gun needs to be ignited and launched, and the firing range is at most 200 meters, and the cavalry charge that gathers about 500 meters has already arrived in front of you in less than a minute, and the bird gun can shoot two or three times in such a short time, which is very good. Such an efficiency did not really kill the cavalry, and the people rushed over, and at that time. The bird gun in his hand became a burning stick, and it had no effect.

Because of the quality of the bird, the barrel is often blown up, which will cause damage to the surrounding sergeants.

Speaking of artillery, the most powerful Hongyi cannon. Its weight reached more than 4,000 catties, and it was extremely difficult to transport, and in the face of cavalry that was known for its speed, although it could form a certain degree of damage, but because of its bulkiness, it could not move quickly, and it could not ultimately determine the outcome of the battle.

The Hongyi cannon is used to defend the city, but it can play a huge role, and it is precisely because of this that the imperial court will spend a lot of money to buy a certain number of Hongyi cannons.

The most important thing is the court and the army. There are major problems in the concept of the use of artillery, although there is a Shenji battalion in the army, but in terms of the centralized use of artillery, there is basically no independent system, let alone the birth of an artillery battalion that can later determine the direction of the war.

Under such circumstances, Bi Maokang, a top firearms expert, could only study firearms in Nanjing alone, although with a book such as "Illustrated Weapons of Weapons", he was also not taken seriously by the imperial court.

Zheng Xunrui, who has crossed over, of course, does not think so. When it was decided to develop firearms on a large scale, Bi Maokang was the first person he paid attention to, on the one hand, Bi Maokang was a firearms expert in the Ming Dynasty and had a special discussion. The invention of the world's first flintlock pistol, abandoning the limitations of arquebus, so that the flintlock pistol can be used in rainy and snowy weather, which is a major progress in the development of firearms. Perennial development of firearms, for many advanced concepts, can be accepted in the shortest possible time.

After the Nanjing Firearms Bureau moved to Huai'an, the next thing Zheng Xunrui needed to do was to get Bi Maokang to Huai'an.

If you want Bi Maokang to come to Huai'an, it is not so simple, after all, he is the right attendant of the Nanjing Ministry of Rites, although he has no power, and there is not much to do, but the identity is there, and the high-ranking officials of the three grades of the people, in today's words, must have such a big temple to be able to accommodate such a Bodhisattva.

In a short period of time, there is almost no possibility of transferring Bi Maokang to Huai'an, and the best way is to let Bi Maokang go to Huai'an to guide the relevant matters of the Firearms Bureau.

After careful consideration, Zheng Xunrui wrote a letter to Bi Maokang, in order to write this letter, Zheng Xunrui carefully read the book "Illustrated Weapons", you must know that the book "Illustrated Weapons" cannot be found on the market.

In the letter, Zheng Xunrui put some of his own understanding through it, focusing on the flintlock pistol, affirming the historical innovation of the flintlock pistol, but also unceremoniously pointed out the problems of the flintlock pistol, for example, the fired bullet also needs to be poured into the outlet of the barrel with a strip, when firing, the trigger hits the flintlock and fires, and it takes a huge amount of strength to pull the trigger, and the muzzle velocity, trajectory, and range of the bullet are not as good as the relatively mature bird gun, etc., if these aspects are not improved, the degree of promotion of the flintlock pistol is limited.

Zheng Xunrui said very directly, without the slightest cover-up, and abandoned the roundabouts and cover-ups in the officialdom.

This was deliberately done by Zheng Xunrui, because he knew that Bi Maokang was not a real official, and that all officials like Da Maokang who studied a certain aspect of scholarship had a straightforward personality, and Bi Maokang did not delve into firearms to the point of obsession, nor could he invent a flintlock pistol.

Since it is not possible to transfer Bi Maokang to Huai'an through positive channels, then use the method of agitation to let Bi Maokang take the initiative to come to Huai'an, so that many problems can be avoided.

Zheng Xunrui's approach has worked very well.

Bi Maokang did not reply directly, but went straight to Huai'an to ask to see Zheng Xunrui.

When I first met Bi Maokang, Zheng Xunrui was very impressed.

Bi Maokang's face was very pale, this was the result of the lack of sunlight and long-term time in the house, presumably Bi Maokang, who specializes in firearms research, could not have had a lot of time to hang out, I am afraid that most of the time was spent in the house.

Bi Maokang had an unconvinced look on his face, although Zheng Xunrui's grade was higher than him, but when they met, Bi Maokang's attitude was not particularly good, after all, the flintlock pistol that he had worked so hard to invent was actually denied by a layman, and this kind of anger was unbearable.

Zheng Xunrui did not talk to Bi Maokang at the Governor's Palace, and after a brief greeting, he took Bi Maokang to the Firearms Bureau.

During the visit to the first and second areas of the Firearms Bureau, Bi Maokang's face slowly changed, from the initial indifference, to the later shock, especially in the second area, after seeing the production of many parts of the flintlock pistol separately, and with strict standards and scales, as well as almost strict quality standards, he couldn't help it.

Bi Maokang's exchanges with Tang Ruowang, Bo Yu, Long Huamin, Deng Yuhan and others also began at this time, and he knew these people, and he also made great achievements in the research and development and manufacturing of firearms.

In fact, before Bi Maokang came to Huai'an, Tang Ruowang and others were understanding the foundation of the principle of the flintlock pistol, and began to improve many details of the flintlock pistol according to the ideas provided by Zheng Xunrui, striving to make the operation of the flintlock pistol more simple, and the biggest change was to assemble a bayonet on the barrel of the flintlock pistol.

Picking up a flintlock pistol that had been improved in detail, and looking at the bayonet that could be disassembled at any time in front of the flintlock pistol, Bi Maokang's eyes lit up and his body trembled slightly.

Bi Maokang didn't even pay attention to Zheng Xunrui, who was by his side, and talked to Tang Ruowang and others intently, for the major changes in the details of the flintlock pistol, he didn't look so simple, any change in the details, it needs to be carefully considered, a lot of things, after manufacturing, it looks very easy, but I don't know that it takes a long time to think of such an idea, of course Bi Maokang, who knows the truth, knows.

As the conversation deepened, Bi Maokang realized that all these changes in details were proposed by Zheng Xunrui.

At this time, Bi Maokang began to really pay attention to Zheng Xunrui around him.

Of course, Bi Maokang didn't know that Tang Ruowang, Bo Yu and others had not yet put forward the fundamental changes in the flintlock pistol, that is, the changes in muzzle velocity, ballistics, rate of fire and flint impact fire, and Zheng Xunrui's suggestions in this regard needed to be truly improved after countless tests.

Bi Maokang didn't want to leave the Firearms Bureau, and in the public house in the first area, he spoke to Zheng Xunrui.

"Lord Zheng, Xiaguan has no eyes, I can't imagine that these improvements are all raised by adults, Xiaguan Yelang is arrogant, and I ask for your forgiveness."

"Lord Bi should never have such thoughts, the flintlock pistol was developed by Lord Bi with great painstaking efforts, and the official is also very concerned about firearms, after careful study, I have some feelings, if Lord Bi is interested, you might as well stay in the Firearms Bureau and study with Lord Tang, Lord Bo, Lord Long and Lord Deng."

"The lower officials can't ask for it, but it's just bothering the adults."

"It doesn't matter, many of the official's feelings have all been discussed with Lord Tang, Lord Bo, Lord Long and Lord Deng, whether these opinions are reasonable, after Lord Bi understands the reason, he will be able to make a judgment."

Of course, Zheng Xunrui will not talk to Bi Maokang about theoretical matters, although he said that he has read a lot of documents on firearms and artillery, but he has a specialization in the art industry, and he is not an expert in this field, and he can only rely on his understanding hundreds of years ahead of his time to get to the point of the outline, and as for the real research and creation, it is an expert's business.

However, this move is very good, not only for Bi Maokang to stay, but also in the next process of development and creation, Bi Maokang will spare no effort.

It is very important to grasp a person's mind, especially for those professional talents, give enough respect at the same time, but also take some radical methods, so that they do things willingly, which is much better than forcing them to do things. (To be continued.) )
