Under the guidance of Feng Chengshi, Zheng Chenggong walked into the newly established firearms workshop in Kinmen.

The firearms workshop is located at the foot of a mountain not far from the Kinmen military camp, covering an area of more than 100 acres, with more than 300 craftsmen and apprentices, including a gunpowder workshop, an artillery workshop, a musket workshop, an iron shop, a wood workshop, etc.

As soon as he walked into the gunpowder workshop, he heard the sound of striking iron, and hurriedly asked, "Hengchen, what is this gunpowder workshop next door for?" ”

Feng Chengshi hurriedly said, "General, next door is the artillery workshop you said you want to manufacture and improve artillery!" ”

Hearing that the gunpowder workshop was next door to the artillery workshop, Zheng Chenggong was furious and shouted: "Nonsense! You're trying to kill someone, and call someone to stop the fire right away! ”

Seeing that the general was angry, Feng Chengshi immediately panicked and hurriedly said, "Yes!" Be! Be! The subordinates told them to stop. ”

Feng Chengshi hurriedly sent a Xiao Shi to the next door to ask them to stop work.

Hearing that the knocking sound next door stopped, Zheng Chenggong breathed a sigh of relief, and said in an unkind tone: "The gunpowder shop is most afraid of open flames, once it catches fire, then this gunpowder shop is the biggest cannonball, it will explode and kill people!" ”

Feng Chengshi heard the sweat, hurriedly put his hands in the sweat, and said with his fists trembling, "Subordinates should be damned, since the subordinates feel that gunpowder is going to be used in artillery, so they want to get closer, and it is convenient to know the effect." I didn't expect such a big hidden danger. Please also punish the general! ”

Zheng Chenggong stabilized his anger, now is the time to employ people, and he can't chill the hearts of his subordinates.

Zheng Chenggong picked up Feng Chengshi and said gently: "Hengchen, you don't have to blame yourself too much, the disaster hasn't happened yet, and you are not derelict in your duties." Ask people to keep artillery workshops, iron shops, and other workshops that need to use open flames away. It's just Hengchen, since you are an official of the Ministry of Industry, in addition to organizing production, you also need to know more about the most basic knowledge. Learn more and learn more, otherwise how can I trust you with the heavy responsibility? ”

Feng Chengshi hurriedly said, "Yes! The subordinates must remember the words of the general, study hard, and they will not disappoint the general! ”

"Good! Henson leads the way ahead and takes a look at the gunpowder shop! ”

"General, please!"

As soon as he approached the gunpowder workshop, a very unpleasant pungent smell rushed straight to Zheng Chenggong's nostrils.

Zheng Chenggong suddenly felt sick to his stomach and wanted to vomit, and finally held back the disgusting smell and walked into the gunpowder workshop.

When I went inside, I saw that the workshop was full of dust.

Zheng Chenggong hurriedly covered his mouth and nose with his sleeve, and waved his hand a few times before he could barely see clearly,

Everywhere charcoal, sulfur, and saltpeter are piled up haphazardly in the corners, and a dozen empty wooden barrels are piled high.

Several workers are weighing something granular with a weighing rod, then mixing several materials together and placing them in a wooden barrel

After the confirmation of a master, a burst of gunpowder was born.

Seeing those workers, with their sticky eyes, sallow faces, and black and gray colors, Zheng Chenggong knew that it was because of long-term exposure to toxic substances, which caused problems with his health.

Zheng Chenggong saw this terrible environment and said to Hong Dengshi, "Wait until later, send someone to make a mask out of cotton cloth and distribute it to these workers, and at the same time ask someone to open a few more windows to ventilate." This kind of sealing is not only bad for the health of these masters, but also prone to accidents! ”

Although in this era, the protection work cannot be as perfect as in modern times, but what can be done, Zheng Chenggong wants to do it.

Feng Chengshi was puzzled, "Is it necessary, General?" These workshops have always been like this, do they need to be so troublesome? ”

Zheng Chenggong shook his head, although Feng Chengshi has good organizational skills, he is also interested in these hobbies.

But even if he was in charge of the Ministry of Works and often came into contact with craftsmen and blacksmiths, he looked down on these workers in his heart.

For this kind of scholar whose thinking has been frozen, Zheng Chenggong is not interested in persuasion now, nor does he have the time to change their minds.

Zheng Chenggong directly ordered, "Don't ask so much, just do it!" ”

Seeing that Zheng Chenggong was resolute, and those didn't cost much, he hurriedly replied: "Yes, general, my subordinates will call someone to do it!" ”

"Hmm!" Zheng Chenggong continued to look at the production process of gunpowder and asked, "What materials are these gunpowder made of?" ”

Feng Chengshi hurriedly replied: "It is made according to the three materials mentioned by the general before, and his subordinates have asked people to experiment hundreds of times according to the materials mentioned by the general, and finally found that the gunpowder synthesized by seven and five charcoal, one percent of sulfur and one percent of saltpeter is the most powerful." But the power is a little unstable! ”

Hearing Feng Chengshi say that the power was unstable, Zheng Chenggong grabbed the gunpowder in the barrel with his hand.

The power is sometimes big and sometimes small, what went wrong, it stands to reason that this should not happen!

Zheng Chenggong checked the situation as he walked.

Seeing the particles of gunpowder in the barrel, Zheng Chenggong leaned over and grabbed a large handful of gunpowder with his hand.

Touching this gunpowder, Zheng Chenggong knew what the problem was!

Most of the raw materials of gunpowder have not undergone further processing, and they are all lumpy.

Zheng Chenggong put down the gunpowder, clapped his hands and said: "Hengchen, ask someone to grind the selected saltpeter, sulfur, and charcoal into a powder state with a grinding stone, the finer the better." Mix it into gunpowder according to the proportion, and then press the gunpowder powder into a high-density and uniform composition of the medicine cake, then break the medicine cake to obtain the particles, sieve the powder and too fine particles with a funnel, and then sieve, so as to obtain the particle gunpowder of basically the same size, which is more powerful and more stable! ”.

Hearing the general say this, Feng Chengshi didn't know why he was doing this.

But the recipe for the new gunpowder was provided by the Great General, and it was more powerful than the ones with the added mess.

Feng Chengshi believed that what the general said must be correct, and was ready to make new gunpowder according to what the general said.

After dealing with the gunpowder matter, Zheng Chenggong thought that since he came, he would also go to see the artillery manufacturing technology of this era.

Walking into the blacksmith shop where the artillery was made, it was baked by fireworks for a long time, and the tiled house was black.

Squatting on the ground was a bronze cannon, the body of which was almost as thick as a bucket, but the barrel of the cannon cavity was only the size of the mouth of a bowl.

There were some iron rings scattered on the ground, and they were about to circle the cannon body and add strong hoops to prevent it from exploding.

In order to save the image and see that the general's army attaches great importance to artillery, Feng Chengshi was busy explaining the production process of artillery.

"General, our artillery is made by the casting method. The wood is dried to make a gun mold, and then a slurry is made with coal ash, yellow mud, and fine sand ginseng with water, evenly coated on the gun mold, and dried.

Immediately after that, the refined copper is burned into copper juice, gradually put into the mold, and after cold cutting, the running mold is disassembled, and the gun body is cast. In the end, as long as the muzzle and bore are smoothed and put on the sports car, you can go on the field to kill the enemy! ”

Zheng Chenggong didn't understand the casting cannon and didn't put forward any opinions. Just say, "Hmm! Let those masters pay more attention to see how to increase the range of artillery while maintaining their power, and tell them that as long as they can improve their artillery, they will be rewarded, and even official positions are not a problem! ”

"Yes, General! The humble post will definitely convey the general's intentions. ”

"When will the grenade be made?"

"With the guidance of the general, the lowly post will definitely create a batch this month!"

"Hmmm! That's good! Zheng Chenggong inspected the workshop.

"Hengchen, this grenade and artillery are important weapons of our army, and they are also one of the keys to whether or not we can recover the rivers and mountains. You have to be more attentive, as long as the development is successful, I will guarantee you a bright future! ”

Hearing Zheng Chenggong's assurance, Feng Shideng immediately surrendered his hand and said: "Thank you to the general, the lower officials will do their best to complete the general's task!" ”

"Well, I'll make a public announcement here and list this as a military forbidden place. At the same time, an additional 1,000 guards will be sent to guard this place. It is absolutely important to note that idlers are absolutely not allowed to enter and peep at military aircraft. Without my orders, anyone who trespasses can be killed on the spot! ”

"Yes, General!"
