"Didn't you explain to the emperor that this is to unite all the forces that can be united?" Liu Guangshi is completely fearless.

"Haha!" Qu Ping said with a smile, "On the Queen Mother's birthday, let's talk about wine again!" ”

Liu Guangshi said: "It's okay." Then drink it again! ”

Qu Ping hugged his fists and said goodbye to Liu Guangshi, and at this time, Lu Ji came from behind and called Qu Ping: "Prince Xiang, Prince Xiang!" ”

Qu Ping turned around and said, "Why are you so angry?" ”

Lu Ji walked over and said with a smile: "Guess, tell you a good news!" ”

"Did I guess, or did you tell me?"

"Let's go down to the prince and enlighten the prince." Lu Ji said, "The fire gun has been successfully developed!" ”

Lu Ji thought that Qu Ping would be surprised and happy, but Qu Ping frowned and said: "Before the gold, I explained to you and gave you the design drawing, it has been almost two years, and you told me that it was successful." ”

Lu Ji said embarrassedly: "It's really that the conditions for making molds and gun bodies are limited." ”

"It's a miniature version of the cannon, what do you say is limited?"

"Yes, yes, why don't you ask the prince to move to the firearms workshop and personally inspect it?"

Qu Ping said: "Let's go." ”

The two went to the firearms workshop under the Ministry of Industry, which is a place dedicated to the development of firearms, and all cannons, grenades, and explosives come from here.

Lu Ji asked people to take a delicate cuboid box, opened it with great interest, and took out a long tubular metal object from both hands inside, which was undoubtedly a firecracker. The surface of the firebolt was coated with a layer of lacquer, which reflected the light.

Lu Ji presented it to Qu Ping and said, "Lord Wang, please take a look!" ”

Qu Ping took it, and saw that the fire gun was about four feet long, thick at one end and thin at the other, the thick end was the mouth of the gun, and the thin end was the handle. The gun tube occupies two-thirds of the front part of the gun body, which is the cavity for filling the gunpowder, and there is a fine hole in the middle and back thirds, which is the place where the lead is placed. Attach a fuse, fill the gunpowder from the gun, mix it with stones, iron balls or lead beads, light the fuse, and fire at the target.

Qu Ping weighed the system, weight, and shape of the firecracker, and was quite satisfied, but he didn't know how it felt and how effective it was.

Lu Ji proudly said: "This is the sixth version of our improvement. Lord, let's go outside and try it! ”

Qu Ping saw Lu Ji looking proud, although he didn't look down on the fire guns of this era, but at least it was epoch-making, so he couldn't hit the information of the developer.

"Let's go!" Qu Ping took the lead with the fire hammer on his shoulder.

Lu Ji beckoned others to bring gunpowder, iron sand, etc., and followed Qu Ping.

When he arrived in the open area outside, Lu Ji took the gun and demonstrated how to load the ammunition himself.

I saw Lu Ji stuffing a fuse into the fuse hole, and then mixing gunpowder and iron sand into the gunpowder tube, and using a drill rod to fill and compact the ammunition in the tube.

Lu Ji carefully handed the fire gun to Qu Ping and said, "Be careful, the prince is careful, the ignition is imminent." ”

Qu Ping has never seen or used any guns, will he still be afraid of this kind of small fireworks, joke!

Qu Ping picked up the fire gun, aimed at a three-inch square water tank fifty meters away, and said, "Ignite." ”

Lu Ji blew the fire fold, lit the fuse, and waited nervously.

The spark squeaked along the fuse and burned into the barrel of the gun, and after a while, only to hear a "bang", the fire light of the gun mouth lit up, and the huge gunpowder momentum backwashed the iron sand out of the gun mouth, bringing out a puff of smoke of nearly two meters.

The water tank fifty meters away was hit by the iron sand sprayed out, and Lu Ji and the others cheered: "The prince has good eyesight!" ”

Qu Ping was very disappointed, although he calculated with clever accuracy and hit the water tank, but the water tank was intact. If this were a different person standing there, I am afraid that I would not be able to kill it.

Lu Ji and the others looked at Qu Pinglu disappointed, and the cheers gradually went out.

Qu Ping threw the firebolt into the previous box and said, "What do you think of the lethality of the firebolt?" ”

Everyone bowed their heads and couldn't speak, the effect just now was obvious, and the water tank only groaned a few times in the face of the attack.

"It's an itch in the boots!" Qu Ping shouted.

Lu Ji said: "The closer the distance, the better the effect." ”

Qu Ping scolded: "If you are closer, do you want the enemy to send his head to the muzzle?" Fifty meters, with this effect, why do the soldiers give up their bows and crossbows to accept your firearms? And the firebolt will take a long time to fill, how to surpass the bow and crossbow and update it? Two years, even if it's a year, you're going to show me this? ”

Qu Ping was furious, and Lu Ji and his subordinates were scolded so much that they couldn't raise their heads.

"I want to kill people, not scary people, let alone entertain people!" Qu Ping continued to spit lotus flowers.

Lu Ji asked curtly: "Then where should it be improved?" ”

"You are Master Luban, and you are a technician of the Ministry of Engineering, why do you ask me?"

"You're the chief designer......"

Qu Ping was speechless for a while, okay, this fire gun was indeed designed by himself, it seems that he looked down on Lu Ji and the others.

Qu Ping's tone softened, took the gun and looked at it carefully, and said, "The barrel is intact, so what's the problem?" ”

Lu Ji thought for a while and said, "Gunpowder? ”

"Of course!" Qu Ping said, "It must be that the gunpowder is not enough, so that the internal thrust is not enough." How to match, you are carefully and repeatedly scrutinizing, you must ensure that at least 50 meters away the water tank is broken! ”

Lu Ji breathed a sigh of relief, it was the problem of gunpowder that would be easy to handle, as long as there were more people and experiments in turn, the best ratio would definitely be found.

Lu Ji sneered and said: "Lord Wang, the lower official guarantees to complete the task!" ”

Qu Ping said: "I am not sincere in making things difficult for you. It's just that what you make, you must think repeatedly in your heart, what kind of situation will the person who uses this thing face, and what requirements he will have, so that everyone will grow! You don't want the soldiers in front of you to lose their lives because of using your products, right? ”

Everyone humbly accepted Qu Ping's criticism, nodded and said, "The prince's lesson is extremely good!" ”

Lu Ji let everyone disperse, then invited Qu Ping back to the room, poured a cup of tea, and carefully handed it to Qu Ping: "Lord, drink a cup of tea and dissipate your anger." ”

"You want me to moisten my throat and then scold you, right?" Qu Ping picked up the tea and took a sip gently. vertex

Lu Ji knew that Qu Ping didn't really want to scold himself, but the time to invite credit was too early, so he attracted a scolding, in the final analysis, he was not careful enough to do things.

Lu Ji said: "Lord Wang, I found a problem. ”

"What's the problem?"

"The problem of the firebolt!"

"There's a problem with my firebolt?"

"It's not that Big Brother has a problem with the design. I found out......" Lu Ji took out a fire fold and two flints, "Big brother, look at these two things, what is different?" ”

Qu Ping glanced at it and said, "The fire fold will blow on fire, and the flints will collide with each other to ignite." ”

"The prince is really discerning!" Lu Ji patted his ass and said, "In this case, with the wisdom of the prince, can there be a way to put the flint into the barrel of the gun, and use the impact to produce sparks, thereby igniting the gunpowder." In this way, the preparation time for shooting will be significantly reduced. ”

Qu Ping looked at Lu Ji in surprise, how could he have come up with this idea, he didn't dare to think about it at that time due to the contemporary industrial standards!

Lu Ji said again: "I can't hide it, I was just thinking about this problem, so I delayed the current progress of the firecracker. ”

Qu Ping said: "Your idea is very advanced. Let me think about it. ”

Qu Ping is familiar with the history of firearms, and Lu Ji's proposal is the principle of flintlock pistols! The fuse can be removed, a flint can be installed at the back of the barrel, and an anvil can be set up behind the flint.

If you want to hit the anvil, you have to have a trigger, and the trigger drives the anvil, and you need a spring.

However, with the current technology, it is impossible to produce such a fine, rigid and elastic spring!

Qu Ping thought to himself, if only he had studied military industry.

Qu Ping caught a glimpse of the bow and arrow hanging on the wall, and suddenly had a whim: why not use the bow and crossbow principle instead of the function of the spring to trigger the anvil? Combine the crossbow with the firebolt, the bowstring triggers, the trigger triggers, the anvils hit the flint, and the gunpowder ignites!

"I'm so smart!!" Qu Ping shouted excitedly.

Lu Ji was pleasantly surprised: "Big brother thought of it so quickly? ”

Qu Ping smiled: "Hahaha! Who am I? Hahaha! ”

Lu Ji was itchy and couldn't bear it, so he hurriedly asked for the scriptures: "What is going on?" ”

"Pen and paper waiting!" Qu Ping said loudly.

Lu Ji immediately took a pen and paper and spread it on the table.

Qu Ping spoke and wrote, carefully describing the principle and structure of the new firearm with Lu Ji until Lu Ji fully understood and mastered its structure.

Lu Ji asked: "Lord Wang, this new-style firecracker, there is no name after it?" ”

Qu Ping thought for a while and said, "It's called - crossbow!" ”

"Guns? Isn't the gun the cold weapon you are talking about? ”

"Then call it a crossbow!"

Lu Ji struck his fists and said excitedly: "It's called a crossbow!" Good name! Lord, I'll start developing it tomorrow! No, today! No, right now! ”

Qu Ping saw that Lu Ji was so excited that he approving: "It's a good thing to have passion. However, you need to make a draft and draw a blueprint first. ”

"I'll draw the drawings now!"

"Okay, then you're busy, I won't bother you."

Lu Ji began to bury his head in drawing, and said: "The next official will not send it far, and the prince will go slowly." ”

"Okay. If you have any questions, feel free to come to me. After Qu Ping finished speaking, he prepared to leave and go home.

The development of crossbow will officially open a new era!

As soon as Qu Ping went out, he thought of another idea, ran back excitedly, and shouted to Lu Ji: "I have a bolder idea!" ”

Lu Ji raised his head: "Bolder? ”

"That's right!" Qu Ping said, "You remember! The idea just now remains the same, so it's called a crossbow. Now this one is the real ballista! ”

"Ballista?"

"That's right! The crossbow is based on the original, the firing device has been improved, but the gunpowder configuration is still the original formula. Now this crossbow is based on the crossbow and improves the ammunition! Qu Ping said.

Lu Ji asked: "How else can ammunition be improved?" ”

Qu Ping drew a longitudinal profile of a bullet on paper and explained: "This is called a bullet. The one in front is called a warhead; In the middle is a cartridge case, which is filled with gunpowder; Notice here later, isn't the flint of the crossbow on the back seat of the ballista, now let's move it to the springtail. In this way, the firing pin quickly hits the flint at the tail of the bullet, triggering the gunpowder in the shell, which generates a strong pressure in the confined space, converts it into thrust, and blasts the warhead in front! ”

Lu Ji couldn't accept it for a while, and asked: "It's so hanging, what is pressure?" ”

"It's the power of oppression."

"Oh, that thrust is the power of pushing!"

"Clever!"

Qu Ping drew a spring on the paper again, and Lu Ji was inexplicable when he saw it, and thought that Qu Ping had scribbled it.

Qu Ping pointed to his painting: "This is called a spring." ”

"I thought it was a coiled snake!"

Qu Ping ignored Lu Ji's ignorance and said: "If you can produce a spring with just the right amount of stiffness and toughness, you can load it into the back of the gun instead of a crossbow, and you will have a real gun!" ”

"What's so difficult about this, make a model and water it with molten iron."

"Then you try to make sure it can withstand repeated vertical squeezing. It's not easy, it's all about finding the right materials! ”
