Wang Chengen's suggestion is quite good, but in order to make Chongzhen more shocked, Zhu Shunjue is more appropriate to use another method: "Princess, there is no gunpowder stored in the current Wang Gong factory, so it will not pose a threat to the emperor's safety." ”

"I think it's better for the emperor to pay a private visit to the new Wang Gong factory."

If someone else said this, Wang Chengen would definitely ask the people in Dongchang to take down this person immediately and execute him for rebellion.

Looking at the rows of hydraulic drilling machines on the bank of the Yongding River, Wang Chengen actually nodded thoughtfully, forgetting the emperor's safety for the time being.

Wang Chengen didn't say yes, nor did he say no, and left from the new Wang Gongchang in a hurry.

Zhu Shun looked at Wang Chengen's hurried figure and smiled, there is a chance that this matter will be done.

Sure enough, as soon as it got dark, Chongzhen took Jinyiwei and Dongchang Fanzi and quietly walked into the new Wang Gong Factory.

At four o'clock in the afternoon, the government had already been released, and all the craftsmen in Wang Gong's factory went back to sleep.

It's just past eight o'clock now, where Zhu Shun is sleeping, lighting a kerosene lamp, sitting in front of the bookcase and writing a book.

Since Chongzhen ascended the throne, he has to correct the chapters almost every day until midnight, and when he saw that Zhu Shun was already dark and still dealing with official business, he suddenly had a sense of identity in his heart that he had met a confidant.

The earlier anger towards Zhu Shun immediately disappeared, and Zhu Shun was a rare incorruptible official, thinking that even if Zhu Shun couldn't complete the delivery of a thousand bird guns, it would be good for him to go to the local government to be a parent official.

Zhu Shun felt that someone seemed to be coming to Wang Gong's factory, and when he looked up, he happened to see Chongzhen, and he put away the hard brush without hurry, and walked out: "Weichen, see the emperor." ”

Chongzhen listened to Wang Chengen's narration, and couldn't wait to see the drilling machine in the water, so he said with a false support: "Aiqing is exempt from courtesy, let me see the hydraulic drilling machine." ”

There is no harm if there is no comparison, Zhu Shun is ready to let Chongzhen first see the traditional bird gun manufacturing, and then demonstrate the power of the hydraulic drilling machine.

Zhu Shun took Chongzhen and the others into a craftsman's workshop, put on a linen placket full of Martian ideas, walked to a stove, first lit the fire in the stove, and then asked a brocade guard to help pull the bellows.

"Your Majesty, there are two ways to make bird guns."

"One is a three-stage joint type, and the other is a double-layer composite type."

Zhu Shun waited until the heat was almost ready, and then pulled out a steel bar, about thirty centimeters long, from the cutting board next to the stove: "This first step is called pipe making. ”

"To build the barrel of a bird's gun, you must first use a steel bar as a cold bone."

Zhu Shun took out a piece of fiery red iron blank from the stove, covered it on the cold bone, picked up the hammer and kept beating the iron blank.

Until the iron blank is rolled into an iron pipe, in this process, Zhu Shun keeps pulling out the cold bones and soaking them in the sink to cool down to prevent the cold bones and the iron blanks from being welded together.

After making a section of the barrel, Zhu Shun took a black cloth towel, wiped the sweat on his face casually, and said, "Anyone who knocks on iron will knock it." ”

"The difficulty lies in the thickness of the barrel, which must be kept at about three points, so that the barrel will be strong and withstand more than a dozen consecutive shots."

"So the quality of a caster's craftsmanship can be seen from this step."

After the demonstration of the first step of tube making, Zhu Shun took over two more sections of the built barrel: "This second step is called welding." ”

"Because of technical limitations, it is not possible to directly build a whole barrel, all of which must be divided into three sections of casting, and the second step of welding is to weld the three barrels together."

"This step is the most critical, and it determines the success or failure of the bird's gun, because if the welding is not good, it is easy to cause explosion."

"This step is more time-consuming, so I won't demonstrate it, that is, after the barrel of the gun is burned red, it is put on a longer cold bone, and it is constantly beaten vigorously."

"In the process of beating, the hammer hand constantly sprinkles the copper powder on the weld opening, and when the three barrels are welded together, the main body of the barrel is manufactured."

"The third and final step is to trim the chamber with a relatively simple drilling machine, and the inside of the chamber is trimmed to a suitable size and the chamber surface is smooth."

"After completing all the previous steps, the most important barrel of a bird gun is made, and then the wooden tray and some small parts are assembled together."

Chongzhen looked at Zhu Shun's demonstration and couldn't help but say: "This is too complicated, how many days does it take to make a bird." ”

Zhu Shun said a very reasonable number that made Chongzhen feel: "The production of the bird gun lies in the barrel, and it takes at least a month to make a barrel." ”

"As long as the barrel is made, it's easy to assemble a bird's gun, just assemble the parts."

Chongzhen picked up a barrel, looked at it carefully, and said, "As long as the time for the barrel manufacturing can be shortened, the production of the bird gun can be accelerated." ”

"I don't know how long it will take to invent the hydraulic drilling machine invented by Aiqing."

People who have never seen mechanized production will be amazed for the first time when they see that machinery can be rotated without human or animal power.

Zhu Shun still decided to demonstrate to Chongzhen first: "Your Majesty, please come with me." ”

After a few steps, a group of people came to the bank of the Yongding River, where the water was turbulent, and Zhu Shun walked into the shed where a hydraulic drilling machine was placed, and picked up a cylindrical iron rod, the same length as the finished barrel.

Zhu Shun picked up the cylindrical iron rod and put it on the tension pliers, turned the runner next to the tension pliers, and clamped the cylindrical iron rod hard.

Pull the starting lever, start the hydraulic drilling machine, and slowly push the tension pliers forward.

The drill bit rubbed against the cylindrical iron rod, and in an instant, a dazzling spark sputtered out, which looked particularly dazzling at night, and it only took half a column of incense to drill through a part.

Chongzhen looked at the length of the drill, calculated the time it would take, and calculated an approximate time: "Half a month?" ”

Zhu Shun turned off the hydraulic drilling machine and said with a smile: "One day." ”

Chongzhen heard such a shocking number, his mouth was a little dry, and he couldn't believe it and confirmed it again: "Aiqing, don't talk nonsense, it really only takes one day?" ”

Zhu Shun nodded solemnly and said seriously: "One day." ”

Chongzhen took a deep breath of the cool breeze in the summer night, calmed the heat and shock in his heart, and was about to speak, when he saw the rows of hydraulic drilling machines next to the Yongding River.

Stunned.

If the invention of the flintlock rifled gun changed an era.

Well, the hydraulic drilling machine was invented.

Chongzhen stands in this era.
