Seeing the emperor's dissatisfaction, Chen Rui explained: "Emperor, the musket structure is exquisite, and there are dozens of processes in total. Each process cannot be careless. If there is a slight deviation, the entire musket will be scrapped. You must first produce ten qualified fuses. Just the scrapped muskets require almost ten. This still requires an old craftsman with more than five years of experience. If it is less than five years, there will be more scrapped muskets."

Wang Fu looked at the coercion in his hand. It was indeed very exquisite. On the side of the smooth wood, there were seven or eight copper parts alone: ​​the machine base, the waiting surface, the hammer shaft, the fuse hammer, the hammer spring, the cap... Each one was polished like a work of art. With the barrel in front, a qualified coercion could be produced in more than a month, which was indeed not slow.

"Why not break down each process, and each person is responsible for one, so that it can be assembled again." Wang Fu said lightly.

Assembly line production is not a major event. It was used as early as the Qin Dynasty. The Qin army dominated the world and defeated the army that was several times more than a dozen of times the six countries. Apart from the courage and fighting, it was inseparable from the production line of efficient weapons behind it. The Qin army fought for years and consumed weapons much more than the six countries, but the manpower was only one-small part of the six countries. With the national strength of about six million people, the Qin army never worried about weapons, and there was nothing else to do except use assembly lines. But for some reason, such assembly line production disappeared after Qin and no one mentioned it again.

Everyone present was stunned. The emperor was simply whimsical. Chen Rui smiled bitterly: "Emperor, how is this happening? There are differences in the production of craftsmen. It is not easy to assemble the components produced by different craftsmen. If it is really produced like this, Weichen probably will not produce a thousand pieces per month."

"Since there are differences, let it have no differences. Set a standard for each component. Only when it meets this standard can it be qualified. As long as all components can be universal, how can there be problems with assembly? This is called standardized production." Wang Fu said proudly.

"This..." Chen Rui stuttered and set a standard for each component. If this is true, of course it can be greatly accelerated. However, the fuse is so fine that each component must be polished repeatedly until it is closed tightly and seamlessly. How can the standard be set: "Your Majesty, I am ignorant and cannot do it."

Chen Rui's words made Wang Fu stunned. He turned to look at Song Yingxing. Song Yingxing was also confused. Wang Fu turned his head to the five old craftsmen who were already gray-haired: "What about you, is there any way to do it?"

"Emperor." Several old craftsmen saw the emperor asking them, and they were about to kneel down one by one. Wang Fu quickly waved his hand: "Several old people are old, please don't kneel."

"Thank you, Your Majesty." The five people did not kneel down, but they all remained silent.

"What, today, I'm not going to blame me, no matter what I say."

The five people looked at each other, and the oldest man raised his courage and replied: "What the emperor said is that the young people cannot do it."

How could it not be done? Wang Fu felt crazy and had to ask patiently: "Why?"

"Back to the emperor, if this method is used on swords, guns, swords and halberds, the muskets are too exquisite, and they cannot be seen at all. They can't be observed with the naked eye, so they can only polish and test them little by little."

Wang Fu felt dizzy when he heard this: "Of course not, no wonder he can't measure it with tools?"

"Tool measurement?" Chen Rui murmured to himself and asked: "Your Majesty, I'm sorry, I'm bluntly saying that tools now cannot measure the accuracy of musket components at all."

Wang Fu finally found the crux of the problem. It turned out that there was no accurate measurement tool. The length units in China were divided very thinly. The smallest units were hu, one foot was ten inches, one inch was ten cents, one cent was ten milli, one milli was ten filaments, and one thin was ten centimeters.

It is also said that one is equivalent to one hundred thousandth of a foot, and one meter is only one hundred thousandth of a meter, and only a little more than three microns. It is more than enough to measure the accuracy of various components of the musket, but this length is only found in the ink of literati and has never been accurately made.

No wonder the standards for components cannot be set. Without standards, assembly line production will naturally not be carried out. It can be done during the Qin Dynasty because the accuracy requirements of cold weapons are not high. Moreover, the Qin State was organized and the laws were perfect. The entire country was like a precise machine running. After the Qin Dynasty fell, the Han Dynasty replaced it with the technique of Huang-Lao. In the past, the Qin State's laws were gone, and assembly line production must be closely organized. This is impossible for the Han Dynasty to do, so no wonder it was lost.

"If the accuracy is not enough, change it. I don't believe it, and I can't make accurate measurement tools."

The emperor's words were like opening a window in front of Chen Rui and others. Chen Rui and Song Yingxing's eyes lit up. Chen Rui patted his thighs: "Yes, if you don't have it, I can't do it."

"I know that there is a thing in the West called a vernier caliper. Using it to measure objects can enlarge the scale that cannot be distinguished by the naked eye. My dear may as well try it out." Of course, Wang Fu could not let Chen Rui and others explore, otherwise the daylily would be cold.

"Vernier caliper, what?" Chen Rui was thinking about how to distinguish between silk and Hu, but he didn't expect the emperor to reveal something immediately.

"Is the vernier caliper? That's it..." Wang Fu explained the principle of the vernier caliper in detail. Chen Rui understood as soon as he heard it: "It's amazing, the emperor forgives the crime, I'll go and see it now." After that, he greeted Song Yingxing, hurried to the craftsman platform, and left the emperor alone.

Song Yingxing smiled bitterly. He has been an official for many years and is not as ignorant as Chen Rui. He hurriedly said to Wang Fu: "Emperor, Lord Chen is eager to do things and is eager to serve the emperor..."

"It's okay, I don't care. By the way, Song Aiqing, have your "Natural Works of Creation" been completed?"

Song Yingxing was very surprised: "The emperor knows the book written by the empress?"

Wang Fu nodded: "Let me do this, my dear gifted a set of books, and the court is responsible for publishing a thousand sets and sending them to various places. What do you think?"

"Ah, go back to the emperor, of course I am willing." Song Yingxing was almost stunned by this sudden happiness. His "Travels in Heaven" was completed seven years ago, but the money was not enough. With the support of his friends, he published dozens of sets. Unexpectedly, for some reason, it was spread to the emperor and he had to publish a thousand sets at once.
