When he entered the production area, Zheng Xunrui's expression was very focused, and he even stood for a while behind a first-class craftsman, who was carefully wiping a flintlock pistol that had just been produced.

The flintlock pistol developed by Bi Maokang was made by these craftsmen.

After a long time, Zheng Xunrui finally asked.

"How long it will take to build a flintlock pistol like this?"

The craftsman's face had already turned pale, and his body trembled slightly, and when Zheng Xunrui came in, he was standing honestly like everyone else, but Zheng Xunrui asked him to continue to do things, so he wiped the flintlock pistol that had been made.

After Zheng Xunrui opened his mouth to ask, the craftsman was stunned for a moment, and naturally spoke.

"It takes about ten days for the small one to make this flintlock pistol."

"Well, you are a first-level craftsman and it will take ten days, so how long will it take for second-level craftsmen and third-level craftsmen."

Zheng Xunrui heard this question, and the craftsman's face showed a trace of pride, you must know that Lord Bo Yu's requirements are very high, among the more than three hundred craftsmen, there are only about ten people who can be rated as first-class craftsmen.

"It takes about thirty days for a second-level craftsman, and a third-level craftsman can't make a flintlock pistol."

Zheng Xunrui nodded slightly, his face was still very calm.

He has been settling accounts in his heart for a long time, the more than 300 craftsmen of the Firearms Bureau, 12 first-class craftsmen, even if it is running at full capacity, it is to produce about 30 flintlock pistols a year, and 35 second-level craftsmen, each of whom produces 12 flintlock pistols a year, and the total number of flintlock pistols is less than 800 flintlock guns, and the Firearms Bureau still has to produce artillery, according to such an efficiency, the firearms produced every year are pitiful, and in a short period of time, they cannot produce much effect and effect at all.

After returning from the Firearms Bureau, Zheng Xunrui once again locked himself in Donglin Book House for a day.

Early the next morning, Zheng Jinhong, Xu Wanghua, Zhao Danyu, Tang Ruowang, Bo Yu, Long Huamin, Deng Yuhan and others. All came to the Governor's Palace.

There were already some paperwork on the table, which were written by Zheng Xunrui himself.

After everyone sat down, Zheng Xunrui slowly spoke.

"I saw it at the Firearms Bureau yesterday and the overall situation is good. However, there are two questions, and I would like to ask Mr. Bo to return to these two questions, the first question is how many flintlock pistols can be produced by the Firearms Bureau in a year. The second question is how many large and medium guns can be cast by the Firearms Bureau in a year, and the official does not ask how many rockets and mines can be produced. ”

Bo Yu's expression was very solemn, and he thought for a moment before speaking.

"My lord, Xia Guan can only make rough calculations, not very accurately, if all craftsmen work day and night, they can produce five hundred flintlock pistols and ten artillery pieces a year."

"That is to say, there are more than 300 craftsmen, and there is no time to rest."

"That's what my lord said."

Zheng Xunrui asked this question. It didn't attract everyone's attention at all, the Firearms Bureau has always been like this, even the largest Firearms Bureau in Beijing can produce up to 1,000 birds every year, as for artillery, it is about ten guns cast at full power, which has reached the limit.

In order to train recruits in Dengzhou and Laizhou, the Ordnance Bureau in Beijing and the Ordnance Bureau in Nanjing used to work at full speed for about two years. That is, more than 2,000 bird guns were produced, and as for the artillery, all of them were bought from Xiyi.

Seeing that everyone didn't care, Zheng Xunrui sighed softly. After all, the times are different, and the refined division of labor and the production of the first-class assembly line after hundreds of years seem to be like a fairy now, but he must implement such a production concept, at least first achieve the fine division of labor.

A first-class craftsman. To manufacture a flintlock pistol, it takes about ten days, a second-level craftsman needs about thirty days, there must be a gap between the craftsmanship of the two, and the craftsmanship of the first-class craftsman must be better, which indicates that the two flintlock pistols cannot be the same, whether it is in terms of accuracy, or in the degree of trigger pulling, there will be subtle differences, and a flintlock pistol requires a lot of parts, each part is made according to the highest requirements, and finally assembled, and it can be completed in about ten days. That's pretty good already.

But in another way of thinking, the situation must be very different, that is, each part of the flintlock pistol is made according to the unified requirements, and in the Firearms Bureau, this division of labor is refined, for example, a group of people are responsible for the manufacture of gun handles, a group of people are responsible for the barrel, a group of people are responsible for the bolt, a group of people are responsible for the production of springs, etc., that is, the work of producing flintlock pistols is decomposed, so that the unified requirements can also be implemented in terms of quality.

Twelve first-class craftsmen can be responsible for one or several people, and at the same time they specialize in manufacturing a certain part, they are responsible for the technical audit of the whole piece.

The craftsman's salary can also be paid according to such requirements, and the higher the craftsmanship, the higher the income, on the contrary, those craftsmen who are indiscriminately filled will be completely eliminated.

Of course, this advanced production concept, a short period of time may be difficult to accept, this is because the craftsmen of the Ming Dynasty, everyone is the inheritance of the ancestral craft, these crafts are basically incomprehensible, the craft is regarded as a guy who eats, must be passed on to the children and grandchildren, if the craft leaks out, it is equivalent to being served off the rice bowl, that is the matter of deceiving the teacher and destroying the ancestors.

Although the craftsmen have the lowest social status, they have a strong contrast with each other, and the craftsmen with high craftsmanship are respected by other craftsmen, and the craftsmen with average craftsmanship always keep their heads down and their tails between them.

However, the fine division of labor in production is to abandon these views, that is to say, the integration of production is required, and all the parts and components produced must be qualified, and every flintlock pistol and every artillery, any part is not qualified, that is not good, so that the assembled firearms or artillery are sharp weapons to kill themselves on the battlefield.

There have been many lessons in this area of the imperial court, and during the battle of Salhu, because of the unqualified firearms, the result of bird guns abounding, and in the end, the army almost did not dare to use bird guns.

Zheng Xunrui picked up the paperwork on the table and began to carefully talk about the requirements of changing the production process and striving for refinement.

Tang Ruowang, Long Huamin, Deng Yuhan and others were dumbfounded, they were familiar with the principle of firearm production, and they also understood that because the craftsman's skills were not in place, there were unqualified artillery or firearms, but Zheng Xunrui said that this production method can avoid the appearance of unqualified artillery and firearms to the greatest extent.

Each part of the artillery and firearms is manufactured separately, and the parts can be strictly reviewed before assembly, as long as all the parts are qualified, then the assembled artillery and firearms must be qualified.

Tang Ruowang and others only thought of the precision of firearms and artillery production, thinking that such a manufacturing method could avoid the appearance of substandard firearms and artillery, and they never thought that such a production method would greatly improve production efficiency and allow craftsmen to produce more firearms and artillery.

Bo Yu listened more clearly, and understood the meaning in a very short time.

Bo Yu was a little embarrassed, he knew that by doing so, he could ensure the quality of firearms and artillery, but the problem here was whether the craftsmen were willing to really teach the skills of housekeeping.

Bo Yu's expression, Zheng Xunrui can understand.

If everyone sticks to their own technology and is unwilling to communicate, then there will be no progress, and they will always stay on the original foundation, and such craftsmen will eventually be eliminated.

Zheng Xunrui's expression became more serious.

"Lord Bo, the method proposed by this official must be popularized in the Huai'an Firearms Bureau, if there is a craftsman who is unwilling to cooperate, whether he is a first-class craftsman or other craftsmen, the Firearms Bureau will all be abolished, in fact, there are still many craftsmen in Nanjing, as long as the official is willing to recruit, the Ordnance Bureau will not be short of manpower."

"Especially those first-class craftsmen, the skills are handed down from their ancestors, or they have been honed by their own hard work, and they hope to pass on their skills to future generations and rely on these skills to eat, but this kind of thinking will not work in the Huai'an Ordnance Bureau."

"Master Bo, the official gives you ten days to let the craftsmen make a choice, don't force them, the official doesn't want them to be in Cao Ying's heart in Han, what the official needs is willing."

The production workshop of the Firearms Bureau has been comprehensively rebuilt in accordance with the requirements of the fine division of labor.

The renovation does not take very long.

Bo Yu gathered all the craftsmen together, talked about the fine division of labor, and clearly announced that the craftsmen who are willing to stay in the Ordnance Bureau will obey the management in the future, and the future production is directly linked, and the craftsmen who are not willing to stay in the Ordnance Bureau can leave on their own and return to Nanjing, and the Firearms Bureau will not be reluctant.

Bo Yu was given only five days to ask all the craftsmen to make a choice.

Of the twelve first-class craftsmen, two of whom left, returned to Nanjing, and twenty-eight of the second-class craftsmen and third-class craftsmen left.

Bo Yu didn't embarrass them, and Zheng Xunrui didn't embarrass them.

Most of these craftsmen are very old, and they are very stubborn in their understanding, and they do not want their own craftsmanship to be passed on, they think that this is to deceive the teacher and destroy the ancestors, and they are sorry for the ancestors.

In the following time, Bo Yu began to divide the labor according to the individual ability of the craftsmen, and the remaining 290 craftsmen were divided into ten groups, each group of 29 people, including a first-level craftsman, and this first-level craftsman became the person in charge of the production of parts in this group.

Bo Yu himself is the person in charge and personally reviews whether the parts are qualified.

The fine division of labor that should have appeared more than a hundred years later, Chongzhen appeared in Huai'an in ten years. (To be continued.) )
