Seeing that everyone's interest was very high, Liu Yao set a schedule for tomorrow: "Everyone, tomorrow we will look at the damage test of the grenade, and we can also look at the first test of the musket." Pen & Fun & Pavilion www.biquge.info" Yao Ying rarely objected, and probably she was also moved by the vision that she would be able to sleep comfortably next year.

Tang Zuoxiang pulled Zhang Yongkai and said, "The test the day after tomorrow, you tell Mr. about it." Zhang Yongkai was not shy, and said loudly: "We have prepared four live pigs and four live sheep, and we also borrowed two pairs of iron armor and seven pairs of cotton armor from the He Dian. Prepare to put two pigs in one meter, one is iron armor plus cotton armor, and one is cotton armor alone. Put a pig and a sheep at two meters, separate iron armor and cotton armor, respectively. Put two layers and one layer of cotton armor on a distance of three meters, it's three sheep, and I want to see if all three will be blown up. ”

Liu Yao thought for a while and said, "This plan is good. Have you ever considered going a little further? From two meters to four meters? This way we can see how far the grenade can go up to. Seeing that Zhang Yongkai was thinking, Liu Yao said again: "Actually, I still want to know a number: the minimum distance of use of this grenade." At this distance, a thrown grenade will injure itself. ”

Zhang Yongkai thought for a while and said, "Then I'll borrow a few more sheep and put a few at five or six meters." If it wasn't injured, it would be returned to Old Man Yang. Liu Yao nodded first, then shook his head and said, "I'm afraid it won't work, in case it's all injured, I won't be able to finish eating." We can use wooden planks to order from the woodsmith workshop, and ask for the same tree, the same size and thickness, and the same degree of dryness. Such wood allows them to prepare a batch. ”

"Is it okay to do without pigs and sheep?" Zhang Yongkai hurriedly asked, then shook his head and said, "I still have to use it." The wounds of the pigs and sheep should be consistent with the depth on the plank, and the plank can be used in the future. ”

Tang Zuoxiang laughed and said, "I'll talk about you kid Ling." Liu Yao also smiled and asked, "Is this person your apprentice?" Tang Zuoxiang had a smile on his face, and said softly: "He was originally a homeless person, and he came from the next county. There is also the strength to shoot the cannon hole in the place where the mountain is opened. I saw that he was faster than a human being, and that he could blow up rocks a lot, so I asked him to come here to make gunpowder. ”

Liu Man interjected on the side: "But classmate Zhang Yongkai still refuses to come." I don't have confidence in myself. "How do you know?" Yao Ying asked strangely. Liu Man waved his hand again: "Almost everyone here is my disciple. Ha ha. "The literacy classes for the illiterate were organized by Liu Man and her second platoon, so everyone who participated in the literacy eradication was Liu Man's disciple or second disciple. The status of teachers in this society is very high, so now "Teacher Xiao Liu" is like a small leader, and someone has someone to report everything.

Liu Yao looked at his daughter worriedly and said, "Will people think that I am cultivating my own strength?" Actually, I just want you to spread knowledge. Liu Man laughed, and when he saw that his father was very serious, he also replied seriously: "It's normal for you to cultivate your own strength." Which family here doesn't put their own family first? ”

"You've noticed this, too? That's what I'm worried about. Chinese always only think about their own family and surname, unable to establish a public society, unable to treat equally, unable to engage in contracts, family this matter is a great problem for China to build a modern society. ”

"Dad, you're not going to let me stay home and do nothing, are you?" Liu Man asked suspiciously.

"Of course not. I'm not going to trade your future for anything anyway. Liu Yao said very seriously, looked back at Zhang Yongkai and his colleagues who were arranging the experimental site, and said happily: "In the foreseeable future, nothing will hinder you from developing yourself freely." ”

Leaving the gunpowder workshop, the family returned to the industrial area and came to Qian Er's factory. It is still called a carpentry workshop, but the main machinery is actually used to process iron: lathes, drilling machines and hydraulic forging presses. Now they are working in full force to try out the rifle.

The carpentry workshop was expanded to include three workshops along the river, using water to drive machinery. One of them houses three steel lathes, one with three steel drilling machines, and the other with a hydraulic forging press and the earliest hydraulic machine: a disc saw. The workshop is equipped with these mechanical cores, and the original woodworking part is now compressed into a corner of the workshop, so that behind the three workshops, the other three workshops have already begun construction, which will be used for woodmaking and processing rifles. The power source of these three workshops will be another secret weapon that Qian Er is now making: the steam engine.

Liu Ze is very familiar with this place, because Zhang Heng will always make some small toys for him to play with. He took his father's hand and ran into the workshop, found Zhang Heng in the crowd, and shouted: "Mr. Zhang, are there any new toys today?" Zhang Heng was a little embarrassed when he saw Liu Yao's family. Yao Ying hurriedly grabbed her son and said to Zhang Heng, "Thank you for those toys you made." Our kids love it. Liu Yao also grabbed Zhang Heng's hand and shook it and said, "I'll just say that your craftsmanship is good." Not to mention my son, there are some toys that I love to play with. Zhang Heng looked even more embarrassed, and muttered in his mouth: "Carving insect skills, why worry about teeth." ”

Liu Yao laughed and said, "Don't talk about children's toys." Let's take a look at toys for adults. Qian Er took out a long cloth bag and uncovered it, it was a rifle that looked like a shotgun, but there was no trigger.

In the world he came, Liu Yao, like any boy, was very fond of firearms when he was a child. It's just that there is no opportunity to contact in the mainland, and strict control makes imitation guns contraband, which makes everyone doubt that Liu Yao and his party made guns in this world. Fortunately, in the world where he came, he could see programs similar to making guns and changing guns in Discovery, and he was exposed to some information, combined with the information in the scroll, Liu Yao made a design by himself and asked Qian Er to make a sample.

Liu Man looked at the gun and asked strangely, "Dad, why doesn't this gun have a trigger?" ”

Liu Yao fiddled with the gun with great interest, and replied without raising his head: "I told you a long time ago, we don't have sulfuric acid and nitric acid at present, so we don't have gunpowder." Without gunpowder, it cannot be fired with a trigger, only by ignition. After fiddling with it for a while, Liu Yao said to Qian Er: "Come, you can tell everyone the principle of this gun." Qian Er touched his head and said, "Sir, won't this gun be made according to the design you drew?" "I want to hear your understanding. In addition, I would like to ask you, the chief gunmaker, to introduce my family. I'm going to try the gun. Liu Yao walked towards the river with a gun.

Qian Er took out another gun and introduced it as he walked along: "This gun doesn't need to be loaded with gunpowder in front, but uses something called a bullet and stuffs it from the side of the back." This bullet is a paper tube, and there is gunpowder and lead pellets in it, which is the most convenient. Qian Er took out a bullet from his pocket and handed it to Yao Ying, it was a cylinder with a fuse on the side, one end revealing the hemispherical shape of a lead pellet, and the other end was a copper sheet slightly thicker than the diameter of the bullet.

After all, in the world that came, bullets are already a very popular concept, Yao Ying and Liu Man tried not to show their familiarity with the concept of bullets, as well as their surprise at this bullet with a fuse, it really looked like a firecracker, and then listened to Qian Er's introduction: "In order to load the bullet, a hole was opened in the side behind the barrel, which is called a loading hole." But the bullet will definitely not ignite in the loading hole, it will blow up the person who fired the shot, and the lead shot will not have the strength to fly forward. So there is also a ramrod inside the barrel that pushes the bullet forward in front of the loading hole. ”

Liu Yao, who was holding the gun, walked in front, and pulled the push rod back as he walked, revealing the loading hole on the barrel body, which was a rectangular opening, and there was a small opening in the direction of the muzzle, which was an opening for the fuse to pass through. He pulled out a bullet and stuffed it into the barrel through the loading hole.

Qian Er continued: "This putter pushes the bullet forward and pushes it to the place where the loading hole is just gone. The iron plate at the back of the bullet is a little larger than the bullet, and it just gets stuck and can't be pushed forward, and at the same time, the fuse is exposed right here in the small hole at the front of the loading hole. ”

A group of people walked to the Shilu River, Liu Yao stood still on the riverbank, and shouted to his daughter: "Liu Man, keep counting until 60, and then you stop." "Pushing the actuator forward all the way and then down, a slot jams the actuator so that it can't move back and forth. The ramrod hits the back of the bullet, creating an enclosed space, with only a small hole at the front of the loading hole, which just allows the fuse on the bullet to stretch out. The gun was already in a ready state for firing.

A closed passage was formed between the outer wall of the workshop and the river bank arranged along the bank of the Shiroku River, and the two ends and one wall were the site for testing the gun. Liu Yao took an incense stick handed by Zhang Heng, lit the fuse, and immediately put the gun on his shoulder and aimed at the target at the end of the passage. The fuse seemed to burn for a long time, and then I remembered a loud bang, and a burst of fire and smoke came out horizontally from the gun's body, which was the gunpowder flame and smoke that erupted from the hole in the fuse, and the gun body not only recoil like an ordinary gun, but also had an obvious sideways swing action. This lateral swing caused the accuracy of the gun to drop to an intolerable level, and the bullet did not hit the wall of the passage at all, but shot a puff of smoke on the outer wall of the workshop.

Liu Yao smacked his lips a little regretfully, quickly pulled back the pusher, took out the bullet casing that had exploded into a ball of confetti, raised the gun towards the sun, and then looked sideways through the loading hole, and said with satisfaction: "There is no confetti, and the chamber of the gun is quite clean." Then he felt for another bullet, reloaded it, and fired it. The second shot was prepared and fired a little better, at least hitting the plank at the end of the passage.

Liu Man cheered up and shouted next to him: "Dad, hit the plank." Do you want to see how deep you get in? "That plank is 2 meters by 2 meters square, and obviously it is not a good target to hit. Liu Yao turned around and said, "Don't move, I'll see the speed of continuous shooting first." Then count. "Shell again, check the chamber, reload and fire. The shot missed the target again, sending a puff of smoke into the wall.

"Is this wall strong? Will it to the workers inside? Liu Yao checked the chamber of the gun again and asked Qian Er. Qian Er touched his head and said, "The wall is a brick wall, but it's better to be careful." The power of this gun is overbearing. I'm going to have someone put another layer of wood on the outside of the wall. ”

Confetti began to grow in the chamber of the gun. Liu Yao twisted the bullet casing that caused the confetti on his fingertips, took the strip handed over by Zhang Heng to clear the chamber, and said to Qian Er: "Fill the sand between the wooden board and the wall, so that it is safe." After thinking about it, he said, "No, what if the person shoots into the river?" You should go to the foot of the mountain and carve out a piece of land and build a closed shooting range, so that it is safe. Or, you and Tang Zuoxiang share a shooting range. He has a lot of space there, and it's still secretive. ”

After the clearing, Liu Yao loaded another bullet, and as soon as he reloaded, he heard his daughter shouting: "60!" Liu Yao turned back to Qian Er and said, "4 shots a minute, not bad." He threw away the incense, withdrew the bullet from the chamber, and handed the gun to his daughter to familiarize himself with. Liu Ze also stretched out his hands to get the gun. Liu Yao squatted down and said to him: "Guns are not for children to play, you can only play with guns when you are as tall as your sister." Before that, I would shoot you once if you touched the gun, and probably never allowed you to use the gun. Liu nodded aggrievedly, looking a little like he was about to cry. Liu Yao picked up his son and said to his daughter, "Let's go, let's go see the effect of the shot." ”

Liu Man pushed and pulled the push rod in this gun and said to his father: "This gun you designed is really the worst firearm I have ever seen." This kind of accuracy cannot be used. ”

"Well, my daughter, I would like modern firearms, too. However, we do not have sulfuric acid or nitric acid, so we do not have gunpowder, so we have to use a fuse. You've read the section on firearms, right? In addition, our ability to process bullet casings is limited. In short, this is the level that can be achieved at the moment. Terrible indeed. ”

"Sir, Mr. Xiao Liu, this gun is not bad at all!" Qian Er seriously argued on the side. "This gun is overpowering, and it's very fast. The musket usually fires up to two shots a minute, but this one can shoot up to five shots. Sir, you were fighting unhurriedly just now, if you were more compact, you didn't need to clear the chamber, 5 shots were more than enough. ”

"You're right. But it's not allowed. If you don't get the gun, you're going to die. Liu Yao said regretfully, patting Qian Er's shoulder: "It's already good to be able to do this, we can improve it again." ”

"Sir, I was wondering, can I put the bullet hole on it? So that the gun does not swing. When you hit it, you are either holding it with a pole. Zhang Heng came up with an idea on the side.

"That's a good idea." Liu Yao and Qian Er said at the same time. "I'm going to change a few of them, and I can try them tomorrow." Qian Er said excitedly.

"It's not the best idea yet. Dad, you give me this gun, give me a few more bullets, and you give me a few fuses that pull hair. Liu Man was still pushing and pulling the push rod in Kalakala, and asked again: "Dad, I remember as if you said that we can't produce spring steel for the time being, so we can't make a trigger, right?" ”

"No spring steel is for sure. It's just a trigger, and you can use horn pieces instead of springs. Now the horns are used in bows and arrows. Liu Yao replied carefully.

Qian Er quipped: "Mr. Xiao Liu is literate and hyphenated, and he can also get firearms?" Liu Man didn't care, and returned the gun to Qian Er: "I don't want the gun." I think if you get the bullet right, you'll get the gun. As he spoke, he grabbed a few bullets and put them in his pocket. Liu Yao hurriedly pressed her hand: "When you get these bullets, you must be with me." Liu looked at his sister enviously. The sister nodded to her father seriously, touched her brother's head, and said, "There must be a way to solve this, I don't have a clue yet, but I feel a little bit." ”
