"Improvements?" Xu Guangqi was stunned. Pen, fun, pavilion www. biquge。 info

"Yes! Improvement! Let's talk about the bird gun first, presumably Aiqing also knows that today's bird gun has many shortcomings, not to mention the quality problem, there are other problems, the first is because it takes a section of fire rope to trigger the bird gun, so each musketeer has to carry a fire rope up to several meters on his body. Before the battle, they had to light the arquebus, because in wet weather, the arquebus is extremely difficult to ignite, and experienced warriors will light both ends of the arquebus so that they can fire a second shot at any time, so that a single arquebus will not burn for long. In addition, the arquebus is also very dangerous when it is lit, if you are not careful, the spark will ignite the bullet belt on your back, causing an explosion and injuring the musketeer himself, and the lit arquebus can easily expose itself at night, so it is impossible to sneak up on the enemy at night. Chongzhen said and held up a finger; Second, the operation of the bird gun is very complicated, which I needless to say; Then he held up a second finger, "It can't be used on rainy days." On rainy days, water will enter and you will not be able to get angry. In fact, it is not only not allowed to be used on rainy days, but also when the wind is strong, because the wind will blow away the powder on the fire door. And because of the pyrotechnic powder used at the time, it was like a smoke bomb that could seriously blind your own army. Right?" he said, holding up a third finger; Xu Guangqi listened and nodded, "In the end, the effective range is too short!" Chongzhen raised a fourth finger. Xu Guangqi nodded after listening: "Your Majesty seems to know a lot about bird guns, yes, it is precisely because of these reasons that many generals and soldiers prefer to use bows and arrows!" ”

"So I hope Aiqing can think of a way to improve and eliminate these drawbacks, so if the quality is guaranteed, the soldiers will be more willing to use firearms!" Chongzhen Road.

"Your Majesty has a point! The ministers will do their best to try to improve! Xu Guangqi said seriously.

Chongzhen thought for a while and said, "I have an idea, Aiqing will see if it's okay!" So he took the paper and the brush, and began to draw, sighing as he painted, alas! If it is a modern pen, it is convenient, this brush is too difficult to use, alas! According to his own impression, Chongzhen painted a flintlock pistol, although the style is extremely ugly, but it can be seen that it is a gun, looking at his masterpiece, Chongzhen himself is a little embarrassed to show Xu Guangqi, but I don't know that hundreds of years later, this painting was auctioned at a sky-high price in the auction house, and finally was collected by the later government Ming Palace Museum, this is a later story!

"Aiqing, take a look! I drew it according to my own ideas, look at it! Saying that, he handed it to Xu Guangqi, Xu Guangqi took it, frowned, and saw that His Majesty's painting was indeed a gun in his experience, but he couldn't see why, mainly because Chongzhen's painting was too ugly, no way, Chongzhen personally explained that he had only seen it in the forum, and had not conducted special research, so he could only draw it by impression, so he walked down the dragon chair, walked to Xu Guangqi's side and said, "My idea is whether I can clamp a flint on the jaws of this hammer, and there is an anvil on the side of the fire hole, and when shooting, pull the trigger, Under the action of the spring, the flint was struck heavily on the side of the fire door, and sparks appeared, igniting the gunpowder and firing it. This greatly simplifies the firing process, improves the firing rate and accuracy, is easy to use, and most importantly, should also reduce the cost of building and facilitate mass production. By the way, gunpowder can also be wrapped in paper according to the ration in advance, and when you use it, you can tear it directly and pour it in! Isn't this also faster than the original reload speed? Of course, I don't know exactly how it is, and I still need Aiqing to organize some experienced craftsmen to test! ”

Xu Guangqi is an expert after all, after listening to Chongzhen's words, he suddenly felt that his brain was opened, as if he had opened a new door for him, and suddenly became enlightened, and he couldn't wait to organize people to start the experiment now, and said with great joy: "Your Majesty, this method is very wonderful!" Wechen thinks it must be possible, and Chen can't say that it can be completely built, but it's still very possible!

"Excellent! Then I look forward to Aiqing's good news, and this arduous task will be handed over to Aiqing, that's right! This information must not be leaked, not even by your Western friends! Aiqing should be remembered! Chongzhen solemnly confessed.

"Weichen Command!" Xu Guangqi knows that this is not a difficult task at all, and it is an opportunity to go down in history, His Majesty gives himself such an opportunity, this is a great gift, who doesn't want to go down in history! Besides, you can't leak secrets, although Xu Guangqi and his friends in the West have nothing to talk about and learn from each other, they still have a clear sense of what is important, and this will be the most important weapon of the country in the future!

"Then let's continue to talk about improvement, just talking about the bird, now let's talk about the Franc machine!" Chongzhen returned to his position and sat down and said.

"Your Majesty, please speak, Weichen listens!" Xu Guangqi said respectfully, he didn't expect His Majesty the Emperor to know so much about firearms, and the suggestions for improvement put forward were very suitable, which benefited him a lot, he was a person who loves to learn, so he naturally would not let go of such an opportunity, and now he has more admiration in addition to the respect for the emperor.

Chongzhen smiled and said: "Speaking of the Franc cannon, this kind of cannon is still very good for close suppression, but I think the main problem of the current Franc machine is that the gap between the sub-cannon and the belly of the cannon is large, which causes gunpowder gas leakage, so it limits the firing range." So why do we still have to follow such a design, can we design a complete barrel, and then design a valve on the butt of the artillery, which can be opened, and then fill the shell into it, and then close the valve, and then start drawing, Aiqing, you come and see! Xu Guangqi walked to the table and looked at Chongzhen's painting, "You see this is a cannon barrel, a cannon lug is designed here, and there is a cover at the back, which can include three parts, one is the connection department, and there is a back door, which is the part of the cover, and there is the piston, and then there is a latch in front of the lid, which is mainly to fix the piston column and prevent the piston column from retreating when the gunpowder is fired." After that, he drew an internal structure diagram and said: "Here is the pressure relief hole to prevent water inlet hole plug, here is the exhaust hole channel high pressure, here is the fuze body, here is the ignition hole and the exhaust hole, here is the gas storage space。。。。。。 Looking at Emperor Chongzhen, who was seriously explaining while painting, Xu Guangqi's jaw was about to dislocate in surprise, was this really what His Majesty came up with? Where is this conjecture, this is clearly a complete artillery design drawing, and according to what His Majesty said, if this artillery is really made, it can simply become a sharp weapon in war.

After a while, Chongzhen finally finished explaining, took a sip of tea and said, "Aiqing, do you understand what I mean?" ”

Xu Guangqi swallowed his saliva and said, "Your Majesty! How did you come up with the idea of such an artillery design? ”

"Uh。。。。。。 This one....... I read some ancient books, based on the experience summarized by the ancients, and then combined them! Chongzhen said, it can't be said that it is the experience of later generations who watched the forum and then moved others!

"Your Majesty, can you recommend it to the old minister to watch!" Xu Guangqi looked at Emperor Chongzhen longingly.

"I don't know where this book is now, and I've forgotten the title." Chongzhen touched his head awkwardly.

"That's a shame!" Xu Guangqi shook his head and sighed. "But Your Majesty! If you follow Your Majesty, your design is good, but if you use the current artillery-building technology, you may not be able to do it. ”

"That's right! The current clay mold casting cannon technology is really not good, it can be changed! If you give up this cannon building mode, you can use an iron mold cast cannon instead! Chongzhen said speechlessly.

"Iron mold cast cannon?!" Xu Guangqi suddenly understood something, but he didn't seem to understand, as if he was holding a layer of paper, and he almost poked it so lightly.

"That's right! Now the common people make farm tools, don't they all use iron molds to cast in batches to produce farm tools? Aiqing can find experienced craftsmen to conduct experiments, I don't know the specifics, I'm not an expert in cannon building," Chongzhen said with a smile.

"So that's it! The old minister is narrow-minded! Your Majesty! I really want to read these books! Xu Guangqi said with a sigh.

"Uh。。。。。。 Another day, I will find Aiqing again when I think about it," Chongzhen said embarrassedly.

"In addition, whether it is a Franc machine or a Hongyi cannon, it is a spherical solid bullet, this kind of ammunition is inconvenient to load in use, and the power is also small, I feel that it needs to be changed, with the improved artillery I just said, the shell can be designed like this, you see, it is designed to be such an oblong, and then the warhead is made so pointed, the gyroscope that the common people play Aiqing knows, that's it!" Chongzhen said, paused and said: "The Hongyi cannon doesn't have any ideas yet, you can mainly try to see if the iron mold casting cannon can succeed, and if it succeeds, you can transform the Hongyi cannon!" "Originally, I wanted to say that I would see if I could make a rifled cannon, but it is estimated that the current technology should not work, and it is already thankful that I can get what I said before, and the main thing is that the financial resources can't keep up! Chongzhen sighed and said.

"So be it! The task of these transformations will be handed over to Aiqing! Chongzhen said.

"The old minister is fighting this old bone, and he wants to get out what His Majesty said! Lao Chen believes that it can be done! That's right! That one...... Can Your Majesty give these design drawings to the old minister? Xu Guangqi looked at Chongzhen longingly.

"Absolutely! Aiqing went back and studied it well! Good job! I'm optimistic about you! As he spoke, he handed the drawings to Xu Guangqi.

Xu Guangqi excitedly stretched out his hands to take it, folded it carefully, put it on his chest closely, and patted it gently, this is a treasure, it must be kept well! Looking at this cute old man, Chongzhen smiled, "Okay! That's it! If you have any problems, just ask me! I fully support you! ”

"The old minister obeys!" Xu Guangqi said happily.
