Chen Xin walked over and pulled the device a few times under Tian Yi's explanation, which was exactly the same as the bolt of the bolt-action rifle in later generations, except that the firing pin in the center and the corresponding firing mechanism were missing, and it became a thick iron rod. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Stroke the bolt to the left, and then pull it back, the sub-gun is unlocked, and then manually replace the sub-gun, after changing, the gun latch is pushed forward to the top, and then the right stroke is locked, and a reload job is completed.

Chen Xin gave a thumbs up and praised: "Very thoughtful." ”

Tian Yi modestly said, "The subordinates are just doing their own duty." ”

"How much does this cannon weigh now?"

Tian Yi was already familiar with the data, and immediately replied, "The gun body plus the gun carriage, the total weight of the empty gun is 150 kilograms, which can be disassembled into 4 parts to carry, plus the sub-guns After loading the ammunition, each weighs 6 kilograms, and each cannon has 10 gametes, and the whole cannon weighs a total of 210 kilograms." ”

"How's it powering?"

"My lord, according to the new weights and measures, this artillery cannon can penetrate the earthen wall of a 5-story house at a distance of 400 meters with an ordinary charge of 3 catties of iron projectiles. If the charge is strong, the distance can be increased by 200 meters. ”

Chen Xin patted the low infantry cannon and said, "Okay, the power is good, it can penetrate a five-story house and easily penetrate a shield cart full of sandbags, so it will be decided today to produce this infantry cannon with all its might." ”

Then Chen Xin remembered the problem of logistics support, such a cannon logistics is not something that the current platoon-level troops can afford, "Such a heavy infantry artillery is destined to be adjusted to a higher level to match the logistics supply, so the firepower of our army at the squad and platoon level will be weakened, do you have any ideas?" ”

Tian Yi scratched his head and said embarrassedly, "My lord, my subordinates have held many meetings, but I haven't thought about what to do so far, otherwise both kinds of infantry guns will be built, and the new ones will be distributed to high-level formations, and the old ones will be distributed to platoon-level formations?" ”

Chen Xin shook his head and vetoed: "The performance of the new infantry artillery is far beyond the previous one, and it is not worth using limited steel on such backward weapons." ”

The two were silent for a long time, Chen Xin patted his thigh, took out a small book, and began to draw a sketch with charcoal, while drawing, he explained, "This is one of my previous ideas, you give it a try, if it can be successful, I will use it to equip the squad platoon." ”

Tian Yi leaned over curiously and looked carefully.

"I called him a hand cannon, the caliber was 40mm like the old version of the infantry gun, shoulder-fired, firing mechanism and arquebus."

Chen Xin drew the M79 howitzer of later generations, but it was limited to Chen Xin's own ability, and he could not copy the hinged rear loading mode, so he could only change it to the front loading.

Tian Yi thought for a while and said, "With such a large caliber, I'm afraid it will shatter my shoulder." ”

Of course, Chen Xin knew that the M79 had to be matched with specially designed ammunition, otherwise the recoil would really kill people, so he had already modified the drawings according to the magic reform methods of some backward war-torn countries in later generations, although the range would be reduced a lot, but it was enough in this era.

Chen Xin pointed to the drawings and said, "Look at the details of my design, the ignition hole should be opened larger to facilitate deflating, and I decided to use only a 20cm barrel, so that the projectile will be much slower to be discharged and will not hurt the launcher." ”

"That's what I said, but, my lord, my subordinates will have to experiment before I can give you an answer."

"Of course, we have to experiment first, this is the attitude of serious work."

After making a work plan for the future in the firearms workshop, Chen Xin went to inspect other workshops of the ordnance factory.

First of all, the gunpowder workshop, a large blast on the Yalu River before, all the captured and homemade gunpowder since the entry into the dynasty was used at once, and now the gunpowder of the army can not even fight a fierce battle.

Chen Xin asked Xiao Huixing to do her best to increase the output of the gunpowder workshop. "As long as you need it, I will let the troops cooperate with you at any time."

Xiao Huixing confidently assured, "Don't worry, my lord, the craftsmen who prepare granular gunpowder are completely proficient, as long as they find sufficient raw materials." can instantly build multiple gunpowder workshops. The subordinates have already scattered people and established 10 nitrate purification workshops and charcoal making workshops in advance. It's just that the sulfur production is too low, which limits our production capacity. ”

Nitrate can be purified from all kinds of manure, and charcoal is also very easy to solve, and the current process has been able to get very high purity charcoal.

The more troublesome is sulfur, there are no large-scale sulfur mines in North Korea, and it can be collected by various local methods in a short time, but in the long run, it is necessary to find a stable supply of sulfur.

Chen Xin's mind quickly flashed the name Japan, Japan is sulfurous, and it seems that he is looking for an opportunity to open up a trade route with Japan.

Next, Chen Xin went to the Cold Weapon Workshop.

"Your task is very heavy, we have been expanding our army very quickly recently, and the weapons in the team are very messy, I hope you can equip the big shield and spear as soon as possible, and the remaining various knives, bows, knives, sticks and other weapons are lined up."

As he spoke, Chen Xin took out another sketch, "In the future, all spears will use this kind of spearhead." ”

The director of the cold weapon workshop took a closer look, gasped and sighed, "What a murder weapon." ”

It turned out that the sketch was a three-edged bayonet from later generations, and the supervisor was amazed while making a prediction in his heart, "My lord, this style may take a lot of time to build, and it is estimated that the time to lay a spearhead like this is enough to make six spearheads from the past." ”

Chen Xin also knew that in this era of almost all by hand, it was indeed not suitable to make such a complicated thing, but who let Tian Yi surprise him.

"You will go to Tian Yi in a while, their firearms workshop has recently come up with a mold casting method, the workshop directors can send someone to learn it, the casting method to get out of the things, the quality is good, and as long as a little polishing, the accuracy of the connection between the following and the spear shaft is very high."

"Yes, the subordinates will immediately send capable craftsmen to learn." Saying that, the director of cold weapons also began to offer treasures to Chen Xin.

After leading Chen Xin to a workshop, he pointed to a machine and said, "My lord, please see, this is the lathe you talked about last time, we have managed to build it." It is indeed very practical, and a suitable spear shaft can be sharpened in a few moments, and there is almost no difference in size. ”

Chen Xin looked at the simple lathe driven by a donkey in a circle, and asked with a forced smile, "Do you use a donkey as a power?" Haven't tried hydropower? ”

The director also smiled embarrassedly, "My lord, there are still some difficulties in the water conservancy drive and I can't think of a solution, but we are experimenting, and once we have success, we will replace the donkey immediately." ”

After Chen Xin gave some encouragement, he left the cold weapon workshop.

Finally, there's the Armor Workshop.

"How is armor produced today?"

"My workshop is now able to make 20 pairs of Iron Armor per month."

"Why so little?"

"My lord, it's really a shortage of raw materials, a pair of all-iron armor requires 50 pounds of good iron, and there is no fixed place for running around before, plus the iron allocated to our workshop every month is just a little, and it is difficult for a good woman to cook without rice. Although it has been better recently, it is all unbearable slag iron, and after continuous beating, 10 catties can get one catty of refined iron. It's not going to be any faster. ”

Chen Xin had a little headache: "What about cotton nails?" ”
