Speaking of this gun, Mao Geng also took a lot of thought.

Yes, this is a gun. That's what the Eighth Route Army calls it, and all the firearms are called open guns. The Eighth Route Army once made many guns. They were a little more soiled and they still killed the Japanese.

Unlike many guns of later generations, the structure of the guns of Mao's guns is slightly more complicated. This is to avoid the bullet blocking after loading the bullet block. If a pointed bullet is used, this problem will not exist.

It is worth mentioning that the barrel of this gun is also rifled, which is pulled out using a simple wooden pull-out.

The entire gun adopts a pout-type rift design; the bullets are filled with paper shells, and the paper shells are stuffed into the steel sleeves and are equivalent to the all-metal shell bullets of later generations; the ignition device uses iron to hit the cannon and ignite the fire; after ignition, high-temperature airflow is sprayed through the nozzle, which in turn ignites the launching medicine of the paper shell bullets in the steel sleeves.

Yes, in terms of fire-driven, this musket borrowed the mechanism of the impact pulsator bolt. In the 19th century, after the existence of pulsator mercury, Forsyth designed a musket that used pulsator powder to ignite, but there were problems with pulsator powder to ignite, so there were a series of subsequent improvements. The most mature one was the later pulsator. In 1825, the impact pulsator bolt was born.

The thunderbolt is a small copper hat with mercury. It puts the thunderbolt on the anvil with a fire door, pulls the trigger, and the hammer hits the anvil, so the thunderbolt is burned by the impact, which triggers a small explosion in the confined space of the copper hat and the covered anvil. The high-temperature air flow generated by the explosion passes through the nozzle and sprays to the fire door connecting the gun chamber. To put it vividly, the explosion sprays high-temperature gas into the gun chamber through a small pipe, and finally ignites the gunpowder in the gun chamber.

The thunderbolt is designed for impact ignition outside the gun chamber. Each time a shot is fired, a thunderbolt must be consumed. Each time the ammunition is loaded, a thunderbolt must be placed on the anvil before the next shot can be fired. This will of course affect the shooting speed. So later, a complete set of metal bullets was developed, integrating the thunder mercury fire-induced device to the bottom of the bullet, which is the bottom fire. The bottom fire is the bottom fire, and the thunderbolt is the thunderbolt. It took almost fifty years to develop the bottom fire, so the bottom fire and the thunderbolt cannot be simply equated.

The Mao Musket's ignition is similar to the principle of the impact ignition mechanism.

However, the thunder ignition used invented in the 19th century. Ray mercury is a chemical product that has been cross-age. Now that nitric acid is not produced, thunder mercury is even more elusive. Therefore, the Maoers are simple and use materials that have been in this era. Among them, the glass sand can be used to replace it with ordinary sand, and there is no need to use red phosphorus, which can achieve impact ignition.

When I was a child in my previous life, I played match guns and smashing cannons. The memory was unforgettable. Even if I had never heard of thunderbolts and impact bolts, it would not prevent Mao Geng from thinking of similar institutions. When I came to this era, I carried forward the spirit of making match guns and smashing cannons and put the principle of match guns and smashing cannons to the extreme. Mao Geng felt that this was a natural thing.

When musket firing and firing, in the era when there was no thunder and mercury for the time being, using the Song version of the cannon to ignite the fire was almost the best solution that Mao Geng could think of.

To put it bluntly, this Maoer musket already has all the characteristics of a single-shot rifle in later generations.

However, there are some shortcomings, such as being able to shoot alone, and the shooting accuracy needs to be improved, etc. From the perspective of Mao Geng's determination to take the fine route, this obviously cannot be called a mature rifle. Mao Geng thought in his mind that perhaps in another month, he could make a new rifle with comprehensive performance improvement.

But after Lu Jiuyuan saw the power of the musket, he couldn't help but feel excited. Thinking about it, he felt that Mao Geng's attitude towards musket was a bit wrong, so Lu Jiuyuan decided to have a good talk with Mao Geng.

"Yi Sheng, I've seen the musket shooting today and I feel a lot of emotion. I think we have to have a good chat."

Oh, Lu Jiuyuan wants to have a private chat with him. OK, it’s time to have a good chat. I have to tell you a brief moment. So Mao Geng invited:

"Mr. Lu, why not have dinner together tonight?"

"Call me Brother Lu." Lu Jiuyuan immediately thought that today was the New Year, so he smiled and said:

"Don't you go and celebrate the New Year with the Su family?

"There are opportunities in the future."

"Okay, I'll be the host." Lu Jiuyuan was quite conscious of being the host.

"Brother Lu, I'd better invite you! Today I will show my skills and cook two dishes. Please ask Brother Lu to taste them. How about it?"

The dishes made by Mao Geng are very unique, well, delicious, but unfortunately they rarely cook. Lu Jiuyuan smiled and said:

"It's better to obey your orders than respect! How about asking someone else?"

"who?"

"Ye Shi."

Lu Jiuyuan felt that he should find someone to help him, and Ye Shi’s opinion should be consistent with him, and he should be a good helper.

Of course, Mao Geng would not refuse. Mao Geng felt that Ye Shi should be able to understand his thoughts.

On this night of Xiao New Year, Mao Geng, Lu Jiuyuan and Ye Shi gathered together.

"The dishes made by Chief Executive Mao tasted really good!" Ye Shi was the first time he tasted Mao Geng's skills, and he admired them from the bottom of his heart. As a Jinshi, Ye Shi was recognized as the smartest group of elites in this era, but there were mountains outside the mountain and people outside the people. Look, Mao Geng not only had a good brain, but also had good ideas, but even cooking was so delicious. I really couldn't accept it!

Haha, I'm just two of them."

Speaking of cooking, Lu Jiuyuan immediately remembered Chen Liang's "Aliz Dream in Wonderland".

Lu Jiuyuan asked:

"Brother Yi Sheng, tell me, in the science fiction world written by Chen Liang, people can fly in the sky, swim under the sea, have clairvoyance and ears, and just press the button to cook and stir-fry. Even if you have robots to feed them, will these become real, Brother Yi Sheng?"

When Mao Geng heard Lu Jiuyuan say that the robot feeds, he couldn't help laughing. He spit out the vegetables in his mouth with a puff, and then said sorry.

It is not technically difficult to feed a robot. The key is, if that is the case, what is the point of living!

But Mao Geng still answered honestly:

"Brother Lu, I think all the things Chen Liang imagined should be able to achieve in the future. However, I think it's better to eat it yourself."

"Oh, so it's really possible to feed a robot. It's incredible, incredible! Ye was taught! Come, Brother Lu, Brother Yi Sheng, come, have a drink!" Ye Shi was shocked.

Lu Jiuyuan was also happy and did it as soon as he touched it.

"Brother Lu, drink less and pay attention to your health!" Lu Jiuyuan was weak, and Mao Geng was a little worried that he would drink too much.

"I watched the musket demonstration today. I'm happy. I'm happy today. It's okay to drink more!"

Ye Shi only heard Lu Jiuyuan talking about muskets, so he asked with a smile:

"What's so wonderful about that musket?"

"Mustgun, let's put it this way, killing the enemy a hundred steps away is easy to turn. I'm just wondering, why did Brother Yi Sheng create such a powerful musket, but he keeps hiding it? According to Lu's idea, as long as he creates ten thousand muskets and a more powerful cannon, it can wipe out the Jin soldiers and restore the Central Plains."

"Is that true! Is it so powerful? Since that's the case, Brother Yi Sheng should have taken it out earlier. If necessary, Brother Yi Sheng can put down everything else and focus on making this musket." Ye Shi is indeed a qualified helper.

Mao Geng smiled and thought to himself that if he didn't convince the two of them today, he was afraid that Zhao Yan would really let himself concentrate on building muskets tomorrow.

Mao Geng drank a glass of wine, thought about what to say, and then plucked up the courage to say:

"Brother Lu, I admire your brother Lu's mind very much. Brother Lu's words, 'My heart is the universe, the universe is my heart', have a momentum covering the universe in the realm, which is enough to overlook all living beings. Brother Lu is extremely grand, but does Brother Lu know how big the universe is?"

Mao Gengxin said, don’t answer that the bigger the universe is, the bigger the heart, or the bigger the heart is, the bigger the universe is, that’s too mysterious! It’s the same mysterious as the slogan of later generations, “The farther the thought is, the farther the way.”

Fortunately, Lu Jiuyuan just said:

"I have many questions to ask Brother Yisheng today. I want to hear how Brother Yisheng said, how big the universe is, Yisheng, do you know?"

Mao Geng then talked little by little about the astronomy of later generations, such as the boundless universe, the Milky Way, the stars, and planets. Finally, under the astonished eyes of Lu Jiuyuan and Ye Shi, he simply carried a shoddy globe out of the room.

Next, Mao Geng didn't care about so much. While rotating the globe, he pointed and attended class with two Jinshi of the dynasty who were already extremely shocked.

The two were surprised when pointing out that the earth was round! It was shocked when pointing out that there were five continents, and the Song Dynasty only occupied a small piece of land on the earth, and the two were shocked again.

Ye Shi was young and reacted faster. After savoring it, he couldn't help asking:

"Yi Sheng, you mean we are in an endless universe, and we live on this earth. Compared with the universe, the earth is also a drop in the ocean, right?"

"good!"

Mao Geng was thinking that the next question should come soon. Generally speaking, Ye Shi should also ask: Since it is a ball, why don’t people fall from the earth?

But, no, Ye Shi didn't ask, and Lu Jiuyuan didn't ask this question.

Looking at Lu Jiuyuan's expression, he must be thinking about a profound philosophical issue at this moment.

Ye Shi had not organized the next question yet, but Lu Jiuyuan came back to his senses from his reverie and asked a question that Mao Geng had never thought of:

"Brother Yi Sheng, I ask you, the legendary bearded guest traveling across the ocean and founded a country overseas. Tell me, where did he build his country?"

Mao Geng almost forgot about this matter, but he didn't expect Lu Jiuyuan to mention it at this time!

"It should be in Australia, here." Mao Geng pointed to an area in the lower half of the globe and said shamelessly. Mao Geng had already made a plan for this answer, so he didn't have to think about it.

I am just ashamed! I didn’t learn geography well enough in my previous life, and my location and size ratio were all drawn randomly, but the meaning was here.

Lu Jiuyuan nodded and asked again:

“How far is it from Taiwan?”

"It's ten or twenty thousand miles!" Mao Geng only knew that it was quite far away, but he really didn't know how far it was.

"Oh, I understand. Judging from Brother Yi Sheng's attitude, I have repeatedly refused to advocate hasty military use against the Jin Kingdom. It turns out that the focus is not the Jin Kingdom, but here, right! No wonder Brother Yi Sheng is so dedicated to shipbuilding! He also wants to build a novel ship with a 'tumbler' style. I guess he just wants to salvage the secrets of the seabed thousands of miles away first!"

Wow! This can all be associated with it! I was convinced by U! Mr. Lu, what do you want me to say!
