Zhu Youzhen followed Sun Yuanlong into a small house in the arsenal, and saw that the room was full of gun parts, and there was almost no place to put his feet. Pen? Interesting? Pavilion wWw. ｂiquge。 infoA young man was so engrossed in bending the wire that he didn't even hear anyone come in.

"Ergou, Your Highness is here, quickly take out our flint hair and let Your Highness take a look!" Sun Yuanlong roared like this, and the young man was suddenly startled, and when he saw Zhu Youzhen and Yan Ling, he was so panicked that he couldn't even speak, but respectfully handed over a spear.

Zhu Youzhen took it and saw that this gun looked little different from the bird gun at first glance, and the only thing that attracted attention was that the barrel was very long. The barrel of a bird gun is less than one meter long, but the barrel of this gun is 1.5 meters long. In addition, the firing part of the gun is sandwiched with flint, so that there is no need to ignite the firing charge with the fire rope every time.

Zhu Youzhen picked up the gun, and while looking left and right with love, he asked: "I remember that when the flintlock pistol was developed last year, the main reason was that the spring strength was not up to par, which led to the failure of the firing. This problem solved? ”

"Ergou, did you come up with the idea, or did you introduce it to His Highness." Sun Yuanlong saw that the young man was still hesitant, so he smiled at Zhu Youzhen and said, "His name is Wei Ergou, and he is my new apprentice at the end of last year. Don't look at your age, but you are willing to use your brains and work hard. ”

"That's right, it's called blue out of blue!" Zhu Youzhen encouraged, "Tell me quickly, how did you solve the spring problem?" ”

When it comes to professional technology, Wei Ergou is no longer so restrained, and said excitedly: "The prince's flintlock pistol has been carefully studied, but in fact, it is not complicated, but the spring with the trigger is not easy to do." In the past, the springs were always loosened after dozens of pulls, so that the firing pin hit the flint would have no force and would not be able to burst out of the spark. It turns out that the steel wire on the pistol, we don't know how the Westerners made it, anyway, the spring is wound according to the appearance of others, and it looks exactly the same, but it can't be used.

Later, the villain pondered, since our steel is not as good as that of Westerners, why do we have to make springs in the same way as Westerners? The villain did experiments around the spring by himself, and later found two points: first, the smaller the circle around the spring, the more elastic the spring; The second is to wait for the wire to cool down completely, and then wind, which is more energetic than when it is just pulled out. So the villain made a small change to the trigger, replacing the original thick spring with two thin springs side by side. If you try again, you will pull the trigger thousands of times, and the spring will not loosen. ”

"Good!" Zhu Youzhen praised loudly, "You are not a simple young man who can not be limited to imitation, but find and solve problems from practice!" Tell me about the barrel again, why is it so long? ”

Wei Ergou had already relaxed at this time, and said Kan Kan: "Director Sun has a copy of "Illustrated Weapons", and the villain loves to flip through it when he has nothing to do. This Rummy Gun was made according to the pattern in the catalogue. Because when the gunpowder is fired, it will generate a great thrust in the barrel, and as long as the force blocking the air flow in front is less than the thrust in the back, the bullet will continue to accelerate. And once the bullet is discharged, the thrust is gone, so the longer the barrel, the faster the bullet is discharged, and the longer the range. Like this Lumi gun, Director Sun once test-fired, and the range can reach more than 150 steps, which is twice that of the bird gun. ”

"Then just lengthen the barrels of all the bird guns, won't the Qin soldiers be like a tiger with wings!" Before Zhu Youzhen finished listening, he shouted excitedly.

"Lord Wang, it's not that simple," Wei Ergou said busily, "The longer the barrel, the more difficult it is to make." The barrel of the Rumi Gun is less than twice as long as that of the regular Bird Gun, but the yield is less than a quarter of that of the Bird Gun. It takes you to make a Lumi gun, and you can make almost ten bird guns. Moreover, it is difficult to maintain later, reload ammunition, and clean the chamber, so the rate of fire is not as good as that of a bird. ”

"I see, it seems that I thought too simply, and let the young man teach me a lesson!" Zhu Youzhen smiled heartily.

Wei Ergou was startled, and quickly knelt on the ground and said, "The villain is presumptuous for a while, begging the prince to spare his life!" ”

Zhu Youzhen hurriedly picked him up and said sincerely: "How can this be called presumptuous, if you know more, you can teach me a lesson!" Regardless of our status, we only talk about science and practice. The name 'Ergou' is a bit indecent, do you have a big name? ”

Wei Ergou said movingly: "My parents are illiterate, and they don't know how to name names at all." It is said that the cheaper the name, the better the child to feed, so my brothers are called big dogs, second dogs, and third dogs..."

Zhu Youzhen said unconsciously: "This king wants to reward you heavily, and he will also award you medals." When the time comes, as soon as you come on stage and introduce yourself to everyone, won't your name make people laugh? Why don't you give you a new name, would you? ”

Wei Ergou was still stunned, but Sun Yuanlong kicked him in the buttocks, and scolded with a smile: "Your Highness has given you a name, what a great honor this is, your ancestral tomb is full of smoke!" Thank you for your kindness! ”

Wei Ergou reacted at this time, knelt on the ground and asked Zhu Youzhen to give his name. Zhu Youzhen groaned for a while and said: "You are a researcher of firearms, and when the musket is fired, the sound is like a huge thunder, shaking the sky and the earth." Why don't you just call Wei Zhen! Yan Ling, you remember: Sun Yuanlong, the director of the arsenal, presided over the research and development of casting and concocting guns, and was awarded first-class merit! Wei Zhen, a craftsman from the arsenal, solved key technical problems and awarded first-class merit! In addition to receiving the reward according to the standard, an additional 1,000 taels of silver will be awarded, and the medal will be publicly awarded in a few days! ”

This is the heaviest reward in the history of Qin Wangzhuang, everyone is envious, Sun Yuanlong and Wei Zhen are even more flattered, and they can't help themselves. Zhu Youzhen hurriedly reassured: "Old Sun, just forget it if the young man is excited, you are so old, how can you have a handful of snot and tears." I'm almost dry, I'm not done yet! ”

Sun Yuanlong wiped away his tears embarrassedly and answered Zhu Youzhen's questions one by one.

What Zhu Youzhen is most concerned about now is how much the output of the newly developed rapid-fire cannon and flintlock Lumi gun can be. Sun Yuanlong replied honestly: "The casting mold of rapid-fire guns is very troublesome, and the yield is low, as long as there is a sand hole, it will be scrapped." Moreover, the drying of the clay mold is very slow, and it will take at least a month, according to the current production level, it is good to cast a cannon in two months. The Rummy Gun is slightly better, but it can't compare to the Bird Gun. The bird gun can make about ten guns a day, and the Lumi gun can make one in two or three days. Because they had just been successfully developed, without the approval of His Highness, neither of these firearms had yet to be manufactured in batches. ”

"One cannon for two months? This is also too slow..."Zhu Youzhen suddenly felt a little depressed, at this rate, only six cannons are produced in a year, which is really far away and cannot quench the thirst of the near, and it is difficult to meet the needs of the tense war.

When he was depressed, Wei Zhen said timidly: "The villain still has an idea, maybe he can speed up the cannon casting, but I don't know if it will work..."

"Speak! Speak quickly! Zhu Youzhen said as if he had obtained the treasure, "It doesn't work, you only know if you try it!" ”
