Mao Geng was preparing to show the muskets to Lu Jiuyuan. The ugly daughter-in-law always had to meet her parents-in-law, let alone not be ugly at all! As an official in the military weapon supervision, Lu Jiuyuan asked him to take a look first, which was the subject of the question. Of course, the most important thing is that Lu Jiuyuan is not as impulsive as Zhao Yan, and he would not be eager to use force against the Jin soldiers just because he had powerful weapons.

Lu Jiuyuan and Mao Geng got on the carriage under the guards of Chi Liang and Ma Wu. The carriage was moving forward. At first, it was quite stable, but suddenly it became bumpy. Lu Jiuyuan lifted the curtain of the window and saw that this section of the road was no longer a concrete road, but a dirt road that had just been slightly flat. No wonder it was so bumpy.

After a long bumpy ride, the carriage stopped and Lu Jiuyuan got out with Mao Geng.

The road ahead could no longer be carried by carriage. A small path led to a hillside in front. The guard Chi Liang led the way in front, Ma Wu followed behind, and four people walked towards the hillside. After walking past the hillside, they saw a simple long shed behind the hillside. Mao Geng said, and Lu Jiuyuan followed into the shed.

This is a wooden shed, long and narrow. Strangely, only the front and rear parts are covered with bamboo-stringed concrete tiles, and the middle is empty. Both sides are also surrounded by wooden stakes and bamboo-stringed concrete tiles. From the left wall to the right wall, it is only fifteen or sixteen meters, but the length of the front and back is very long, afraid it is more than one hundred meters. Looking from the front, there is a cliff behind the shed in front. Lu Jiuyuan didn't understand the mystery at first glance, but when he looked at the two rounds of targets placed in the shed in front, he understood a little in his heart. It looked like an archery field. Could it be that muskets and archery have something to do with it!

In short, it is very mysterious here. If you don’t enter the shed, you can’t see what’s being done inside.

It was not until Tan Xiaochun came to see him that Lu Jiuyuan came to his senses from his reverie that Tan Xiaochun was said to have been doing a secret job, probably the legendary musket.

Mao Geng explained to the young man next to Tan Xiaochun:

"Kang Xiaolu, come with a clamp."

The man named Kang Xiaolu walked into the inner room and took out a long and strange thing. The most conspicuous one was the iron pipe on it, connected to a piece of strange-shaped wood.

Mao Geng took the thing, handed it to Lu Jiuyuan, and said:

"Mr. Lu, this is the first musket I made earlier."

Lu Jiuyuan took it, touched it, and looked at it. Although this game was strange, Lu Jiuyuan had seen the launch of the cannon before, and after thinking about it, he guessed:

"Did you shoot an iron ball from this iron pipe? This iron pipe is so small, it is not called a small cannon? Is it just called a musket?"

Mao Geng smiled and said:

"Mr. Lu guessed it well, it is called a musket. This is how we divide it. If the caliber is less than 20 mm, it is called a musket. Oh, the diameter of this hole is called a caliber. If the caliber is above 20 mm, it is called a cannon. The principle of guns and cannons is the same."

"Oh, so that's it, I don't know how powerful it is?"

"Just try it." Mao Geng thought to himself, this time he asked you, Mr. Lu to observe. Mao Geng immediately explained:

"Kang Xiaolu, use this comb to fire two shots, let Mr. Lu see."

Kang Xiaolu got Mao Geng's instructions and began to get busy. He first poured some gunpowder into a small iron pool on the right side of the musket, then covered the lid, then raised the gun rod, poured the gunpowder into the gun hole, and stuffed it into a small iron ball of about the size of the hole. Then he took a long iron bar from the next side of the barrel, inserted it into the hole, and poked it inside. Lu Jiuyuan didn't understand why he used an iron bar to poke it. Mao Geng explained that this was to make the small iron ball close to the dense gunpowder.

Next, Kang Xiaolu lit the fuse with a match and clamped the fuse on a clip.

At this point, the preparations finally came to an end, and Lu Jiuyuan felt a little impatient. The preparations for the launch of the musket and cannon were generally not much different, but they seemed to be a little more complicated.

Kang Xiaolu picked up the gun, laid the wooden support on his right shoulder, aimed the muzzle at the target in front, and glanced like an arrow. Then, with his finger, the fuse suddenly fell down. The lid of the small iron pool filled with gunpowder was opened at this moment. With a puff, a ball of flames rose up, and then a burst of fireworks rushed out of the muzzle.

After the gunshot, the target immediately heard the sound of the target:

"The first shot, off-target."

Obviously, it didn't hit.

Mao Geng smiled and said:

"This kind of musket has no accurate head. It can't hit anything in a hundred meters. Forty or fifty meters is okay. Xiaochun, it's time to switch to forty meters."

Kang Xiaolu was busy again. According to Lu Jiuyuan's opinion, this time it was even more cumbersome. Mao Geng introduced that after a shot, the gunpowder residue in the ignition pool and the ignition hole must be cleaned first to avoid blocking the ignition hole.

Lu Jiuyuan paid attention to the timetable in the shed. When Kang Xiaolu took the gun and aimed it again, it had been more than 40 seconds. If this was on the battlefield, after the first shot was fired, I don’t know if there was a chance to fire the second shot.

The second shot rang as scheduled. This time, Lu Jiuyuan saw the wooden target in front and shook it. The target in front reported Kang Xiaolu's results:

"The second shot, the fourth ring."

Mao Geng pulled Lu Jiuyuan to the target. Lu Jiuyuan saw clearly. The target was penetrated with a hole. It was good to hit the target, but it was obviously a bit off.

"Can this kill people?"

"Anyway, it's more powerful than an arrow, right?"

Lu Jiuyuan nodded.

Mao Geng did not intend to use animals to test the power of shooting, not because it was too bloody, but because he did not want people to experience the power of muskets so quickly, including Lu Jiuyuan.

From Mao Geng's current position, he hopes that the secret of the musket will not be leaked. In short, the longer the confidentiality, the better.

"But, it's good to have a good musket. The problem is that the operation is cumbersome and far less fast than the arrow shooting."

"A shot here, you can shoot a lot of arrows there, right!"

“That’s right!”

Mao Geng smiled and said:

"Mr. Lu, don't worry, this gun is the first musket made earlier and it's not very easy to use. Look at the improved musket and it's not too late to evaluate it."

Lu Jiuyuan said in his heart that he didn't know how powerful the improved musket could be. Well, let's see.

Kang Xiaolu brought another musket from the inner room. In Lu Jiuyuan's eyes, this musket was similar to the first musket.

"This is a rifted musket. Mr. Lu wait and see the effect of the gun to see what is different from the first musket."

Kang Xiaolu took the musket, and didn't know how to move his hand. With a click, the musket suddenly broke at the end of the buttstock. No, it was because the barrel turned down at an angle, revealing the inner hole of the barrel with a black hole.

What is this to do?

After a closer look, a small iron tube with copper ring was exposed on the end that was not folded down. Kang Xiaolu then took out a very small thing from a leather bag. The thing looked like a small mushroom. The "mushroom head" was black and gray, and the "mushroom stem" was white.

Next, Kang Xiaolu seemed to tear off something, and then stuffed the mushroom-like trick into the hole of the iron tube. Of course, the "mushroom stem" was facing inward. But it seemed that the "mushroom stem" was a little thicker. It looked like that, Kang Xiaolu took a little effort to stuff it into the hole.

Before he could see clearly, another click was heard, Kang Xiaolu closed the turned barrel and the entire gun became a whole again.

Then Kang Xiaolu broke open a mechanism on the musket. After the mechanism was raised, it was stuck. A piece of iron pillar was exposed to the right of the musket. After a closer look, there was a small groove on the end of the iron pillar and a small hole in the center.

At this time, Kang Xiaolu took out a small red thing from another leather bag. The thing was not much bigger than a mung bean. Well, it was as big as a soybean, but it was flat. Kang Xiaolu put the red flat "soybean" into the small groove on the small iron pillar. After confirming that it was tightened, he picked up the musket and started aiming.

Is this possible to fire? The foreplay looks a bit dazzled, but it is undeniable that it is indeed much faster than the first musket loading ammunition.

When Kang Xiaolu aimed, the wooden target located at forty meters had already been removed. Kang Xiaolu was going to hit the target that was 100 meters.

With a bang, a ball of fireworks spewed out of the muzzle. Lu Jiuyuan thought, this time he would definitely be off the target. Mao Geng is good at everything, but he is a little overkill. Isn't this a waste of intention? It's better to shoot a target forty meters honestly. If you can shoot a seven-ring or eight-ring, it will burn the incense. Alas! Young people, they don't know how to save money, and they can only let everyone hear it.

Unexpectedly, the result of the target reporter next to the target was:

"The third shot, the fifth ring."

"Have you hit it?" Lu Jiuyuan still disbelief.

Mao Geng thought to himself that Lu Jiuyuan was measuring the second musket by the level of the previous first musket. He smiled and said:

"We'll check the target later."

Looking back, I issued an order to Kang Xiaolu:

"Shoot another shot and shoot another target."

So Kang Xiaolu turned the barrel again, loaded the ammunition, then closed it again, skillfully turned the mechanism, pressed the red flat "soybeans", and then raised the musket to aim. After completing this round of movement, Lu Jiuyuan paid attention, but only took eight or nine seconds.

Bang, another shot.

The results reported by the target player this time are:

"The fourth grab, the third ring."

I heard Kang Xiaolu mutter something, but it seemed that he was not very satisfied with his performance.

Mao Geng was not satisfied with Kang Xiaolu's performance today, and thought to himself that you should at least play the sixth and seventh rings.

However, Mao Geng immediately regained his calm expression and asked Lu Jiuyuan to check the target. When he walked to the target area, Lu Jiuyuan was shocked. The target operator reported it to him was not bad at all. He really hit the third and fifth rings, and the one-inch thick wooden board was pierced. At such a long distance, it was so powerful that it was unimaginable.

"Teacher Mao, the power of this second musket is amazing! Lu finally opened his eyes today. As far as I know, ordinary soldiers shoot arrows, killing distances are no more than fifty steps. After 80 meters, they are at the end of a powerful crossbow and cannot penetrate Lu's rays. I didn't expect that your musket can penetrate such a thick wooden board in one fell swoop, and it is so accurate that it can be called a worldly magic weapon. OK! OK!"

"But I've just played the third ring and the fifth ring." Mao Geng felt that the third ring and the fifth ring was a little unprovoked, but Lu Jiuyuan thought it was amazing. Mao Geng thought to himself, Mr. Lu, this is to be in future generations, and the new recruits who had been shooting for a month were better than this!

"Teacher Mao, this second gun is really great, but I didn't understand how this gun fired. What's the wonder of the little mushroom and the little bean?"

Damn! "Little Mushroom"! "Little Bean"! Haha! Lao Lu, you are so funny!

"That little mushroom is like a bullet, a little bean, a cannon."

After saying that the bullet smashed the cannon, I began to explain the principle:

"There is an awl in the center of the hammer with hat. Pull the trigger down, and the hammer hits the cannon with the action of spring force. The awl can hit the cannon at once. At this time, the brim of the hammer seals the gunpowder pool, and the explosion caused by the cannon pushes the high-temperature airflow into the bullet chamber, and Mars is in the chamber. Mars passes through the small hole on the side of the bullet to ignite the gunpowder and the gunpowder explodes, pushing the cork in the bullet and the Minnie lead bullet in the front section of the bullet to move forward at high speed. This is the principle of this gun."

Mao Geng was still afraid that Lu Jiuyuan would not understand, and added:

"Before the bullet is loaded into the chamber, it must first remove the rubber seal and expose the hole. A little spark can ignite the gunpowder inside the bullet through this hole."

"Bullet? Blasting the cannon?"

Lu Jiuyuan's eyes were full of stars, and he didn't know why.

Mao Geng thought to himself, it turns out that I am playing the piano against a cow!

Speaking of which, this second gun was Mao Geng's proud work. Mao Geng thought that this gun was much more advanced than the flintlock rifle in history, and it was also original by Mao's family. Looking at the history of later generations, it is unique.

You know, Mao Geng grew up playing with match guns and smashing cannons in the 1970s.

The 1970s were an era of scarcity of toys, but at that time, the teenagers used bicycle chains and bicycle ring nuts to make their own match guns, inserted a match into the match gun made of iron wire, pulled the trigger, and the firing needle hit the match head. With a bang, the match head exploded, and the matchstick could fly out three or four meters in the crisp explosion. Thinking about it, it was much more fun than the various ready-made plastic toys later.

Well, apart from playing with match guns, they are playing with cannons. There are many cannons packed on one cardboard, just like the later plastic packaging of medicine. One cannon was torn off, and smashed it with a hammer or stone, and the cannon exploded with a bang. Later, there were no cannons on the market, but the memory of cannons was deeply imprinted in Mao Geng's heart.

After understanding the principles of match guns and cannons, it is not difficult to solve the problem of fire-induced muskets. The match heads can explode, and ignition of hammers is a piece of cake. So, Mao Geng invented the cannon-style musket based on this. Mao Geng's cannons have glass sand, red phosphorus, mattonite particles, granular gunpowder, etc., and a layer of wax paper outside is that simple! It's just that the principle of using friction to ignite.

In addition to the design of smashing cannon jet fire, Mao Geng also used many design concepts on this gun. For example, the principle of loading shotguns with a rift, there are competition guns that use hinges to open and close the chamber with a hinge structure. For example, Minnie bullets with grooves and corks, Minnie bullets can automatically seal the gas to ensure the thrust of gunpowder explosion.

The most outstanding thing is that the gun has a fixed bullet steel cover, which can even be considered an integral part of the bullet.

The bullet is paper-shaped, and the paper meets the requirements of flammability. The bullets in the paper-shaped shell are wrapped with gunpowder, glued on the front end, and there are Minnie bullets on the wooden race, which is good, and they look like small mushrooms. When the bullet is stuffed into the bullet steel sleeve, it must be an interference coordination so that the plug can be clamped in the bullet steel sleeve. After that, close the barrel, the barrel and the bullet steel sleeve fit together, and a brass ring on the bullet steel sleeve forms a seal to ensure that there is no air leakage.

After Mao Geng explained for a long time, Lu Jiuyuan finally understood a little, but in general, he still seemed to understand it.

Finally, Mao Geng made a summary that made Lu Jiuyuan stunned:

"This gun has its own shortcomings, and it needs to be improved and changed to a firing needle type. In that case, it can be used to hit nine rings and ten rings."

If the axial firing needle type is used, the force is much better than the hammer firing. I believe the shooting accuracy can be improved by a higher level. Mao Geng thought so.
