Tian Yi looked at the sketch drawn by Chen Xin, made a few strokes, and carefully explored, "My lord, in this way, it can indeed speed up, and a master can guide several apprentices to start work at the same time, and I estimate that as long as I am familiar with it for a few days, I can increase the output to 40 straight knives per day." Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoBut will the soldiers not get used to this kind of straight knife? ”

Chen Xin heard that the speed could be increased, and immediately smiled, "Lao Tian, you haven't been on the battlefield, so I don't know, now, fighting those fish belly troops, as long as the fire gun can solve it." When you encounter an enemy that needs hand-to-hand combat, almost all of them are wearing iron armor, and the slash has little effect, and what you want is a stab. So, now using a straight knife, on the contrary, adapts to the improvement of the battlefield. ”

When Tian Yi heard this, he was relieved, "I'll go back immediately and reorganize the manpower to start work." ”

Chen Xin was surprised: "Didn't you say that the raw materials are insufficient? How can you start building straight knives in large quantities right away? ”

Tian Yi explained, "My lord, there is still a surplus of iron now, and the crucible steelmaking method you taught us is too little good steel. ”

After a pause, he organized the language and continued to explain, "My subordinates have counted the materials, we have seized so many boring palladium, big sticks, and waist knives, although the iron is not good, but after melting, according to the method you taught, you can get ordinary steel to make knives, and the quantity can also last a month, the key is the smoothbore gun, the amount of gunpowder you require to be loaded is too large, we don't have much good steel, and ordinary steel does not dare to be used to make barrels, so the output is low." ”

Chen Xin understood that crucible steelmaking could not be used on a large scale, and now that it was located in North Korea, it was impossible to build a crucible by himself, so he could only rely on the support of two crucibles made by Lao Bai at a cost of energy, "Hey, there is a long way to go." ”

Subsequently, together with Tian Yi, he determined the specifications of several straight knives, and after testing, it was determined that the straight knives that would be used in large quantities by the whole army in the future were named a type of standard infantry knife.

In the end, Chen Xin came to the gunpowder workshop that he cared about the most.

Xiao Huixing, the manager of the gunpowder workshop, pointed to a row of cauldrons that had been erected and explained, "My lord, we now forcibly collect nitrate-containing soil from the toilets, pigsties, and cattle pens in the surrounding villages and towns every day, crush the fine, mix it with plant ashes, put it into a cauldron to heat and boil, and then pour out the solution inside and filter it, and each pot of soil can be used repeatedly and repeatedly." ”

Chen Xin entered the workshop, was instantly overwhelmed by the strong smell, and wanted to cover his nose with his hands, but seeing that everyone was working casually, it felt too rude, so he couldn't bear to cover his nose, smelled the smell, nodded, and signaled to continue.

Xiao Huixing led Chen Xin to another row of cauldrons and said, "The obtained solution will be heated again, and the water will be evaporated, and you can get relatively pure nitrate." ”

"My lord, please here, let's spread out a few steps as much as possible to prevent accidents, and other workshops for grinding toner and sulfur powder, my subordinates won't take adults to see them, because they are full of smoke and dust, and it's too choking."

As he spoke, he led Chen Xin to a workshop a hundred steps away, pointed to the busy crowd and explained, "This is the place where nitrate, toner, and sulfur powder are thoroughly mixed with water in proportion. ”

After walking a little further, he pointed to a row of ventilated sheds and said, "My lord, please see, this is the place where the gunpowder is dried in the shade, and after it is dried, it will be carefully crushed into fine powder in the room on the side, and finally the surface will be polished with a roller, and the granules of gunpowder will be made." After that, it is sent to the packaging workshop, where it is wrapped in thick paper and formed into a fixed load. ”

After everything was introduced, Xiao Huixing saluted respectfully and said, "My lord, take a look, is all this the same process as what you said at the beginning?" ”

Chen Xin knew that the future development direction of the army would definitely rely more and more on firearms, and firearms without gunpowder would be scrap iron, so he was most concerned about the gunpowder workshop.

As a liberal arts student, Chen Xin racked his brains and finally vaguely thought of the process of making granular gunpowder on a large scale and quickly in this era.

Chen Xin just said a rough idea at the beginning, but he didn't expect that Xiao Huixing was really a talent, and he restored the steps without any mistakes.

In fact, the Ming Dynasty had granular black powder for a long time, and the granular black powder made by the method provided by Chen Xin was only a little different in process and purity.

Granular black powder, compared with the traditional powdered black powder, has the advantages of faster combustion and greater explosive power, and the nature of granular black powder is stable, and it will not be separated from sulfur and nitrate after a long storage time like powdered black powder, and the water absorption of granular gunpowder after polishing is also greatly reduced, and it is not easy to get wet.

Combined with the current level of craftsmanship and raw materials at this time, granular black powder is now the most suitable for Chen Xin's army.

Chen Xin picked up some granular black powder that had not yet been wrapped in a paper shell, and asked Lao Bai to test it, and sure enough, under the strict control of the foremen, the purity of the self-produced granular black powder had reached a very high level.

Chen Xin was very satisfied, but smelling the stench in the air and looking at the nitrate workshop that had left hundreds of steps, Chen Xin said, "The working environment here is too bad, although the work of boiling nitrate is done by North Korean prisoners, but I can't treat them too badly, I will make the cotton cloth used in the clothing to make thick masks, and when it is done, you can send it to the laborers, and it can also isolate a certain smell." ”

After visiting the workshops, the commanders of the various units threw themselves into the large-scale training in full swing.

The personnel who rotate out on patrol every day are also actively searching for various artisans and ore veins.

Everyone heard the officers in the team say that they want to change into a flintlock smoothbore gun that is much more powerful than the current bird gun, and that kind of gun can actually break the iron armor in 80 steps, and even more in 30 steps, and they are all excited and can't sleep for several days.

However, due to the lack of manpower and raw materials, it is not yet known when this flintlock smoothbore gun will be able to be reloaded by the whole army.

As soon as they discussed, they worked together to help the brothers of the ordnance factory to inquire about the craftsmen and the mines when they went out on patrol.

Chen Xin was very satisfied with the atmosphere of mutual help, unity and friendship in the army.

Recently, Chen Xin has not been idle, and after his daily routine physical and equipment training, he began to find time to compile textbooks and teach officers and reserve officers to learn various knowledge in the evening.

Also take time out to talk to people and understand what is going on to make sure the team doesn't deviate from your control.

On the 26th, the guerrillas outside sent back the letter with falcons, and after Chen Xin opened the letter and translated it to the cipher table, he smashed it on the table with a fist, and scolded hatefully, "It's really the mud that can't support the wall." ”

The brush on the table bounced up and tumbled to the ground.

The big cat came over, bent down to pick up the brush, blew the dirt on the stick, and asked, "Why are you so angry, what's wrong?" ”

Chen Xin took a deep breath and suppressed his anger, "It's not the North Korean army, the original 10,000 defenders in Pyongyang, plus less than 20,000 horses and horses who were scared away by us, a total of 30,000 troops, I didn't even see the face of the Jin army, and I actually abandoned the city and fled." ”
