Nitrocellulose is called collodion in Europe. This thing was a chemist who accidentally spilled a mixture of nitric acid and sulfuric acid. In a hurry, he took his wife's apron and wiped the mixed solution of nitric acid and sulfuric acid. (Some

The saying is a rag)

This kind of thing is actually a type of smokeless gunpowder. Li Xiao originally planned to tinker with this thing to make custom-loaded ammunition. It is also the kind of bullet with a primer in later generations, but the current processing technology is too rough. There is no such thing.

Machinery can process a tightly closed gun bore, and even Li Xiao couldn't even produce alloy steel for firearms.

This involves material science knowledge, if Li Xiao still knows something about firearms. Material science is a subject that requires specialized training, and Li Xiao has no choice. In fact, Yu Lao's phosphorus-added steel has exceeded Li Xiao's surprise

.If he tinkered with it by himself, he wouldn’t even be able to make phosphorus-added steel. You must know that the proportion of phosphorus in phosphorus-added steel is very important. Adding too much will seriously damage the performance of the steel, and adding too little will not meet the requirements. It’s the old man who adds phosphorus.

I don’t know how many years of experience the craftsmen have in steel.

The so-called guns these days are all muzzle-loading guns. The front chamber is loaded with powder and fires metal ball projectiles.

The projectiles are usually lead bullets, with a small amount of steel balls or iron balls used. Most of the time, they are used for whatever they have. But I haven't heard of anyone who is rich enough to use gold or silver beads.

Because of the shoddy manufacturing of the projectiles, many times the projectiles were not actually ejected after being fired. And the soldiers did not know whether their bullets were ejected. It is said that there is a record in Europe of ten projectiles being stuffed into a gun barrel!

The biggest weakness of the forward-lying gun is actually the rate of fire. Especially the matchlock gun, the rate of fire is outrageously slow. Now Li Xiao's solution is to first speed up the rate of fire of the gun, so as to improve the performance of the musketeers on the battlefield.

The lethality and ability to fight against cavalry.

"Clamp a piece of flint on the jaw of the hammer, and get an anvil next to the fire hole. When shooting, pull the trigger, and under the action of the spring, hit the flint hard on the side of the fire door. Sparks will appear and ignite the fire door.

"Light the gunpowder to fire." Li Xiao kept drawing on the drawing, because his painting skills were really not very good. Mr. Yu and Daofuyou could clearly understand what Li Xiao was saying, but they couldn't understand what he was drawing.

"Okay! Okay! We understand!" Li Xiao was once again invited out by the two old guys.

For a guy like Li Xiao who only understands theory and has almost zero practical ability, he can just give some guidance outside the field. As for the actual practice, it is up to two old guys to do it.

The sound of reading could be heard loudly from the new school in the distance. The textbooks were enlightenment books brought by Mr. Wu from Hebei. Li Xiao read for a long time but couldn't understand much. They were all awkward classical Chinese texts. There were also many eight-legged essays in them.

Li Xiao knew every word in ". But if they were connected in a string, Li Xiao wouldn't be able to understand. When those words are combined, it's like another language. Li Xiao is very worried that Mao Wenlong has taught these children to be nerds.

.

In Mao Wenlong’s words, are you considered a scholar?

However, this is consistent with Li Xiao's life experience, a young man from a remote village. It would be too suspicious if he even knew something as high-end as eight-part essay.

Li Xiao's worries did not arise, because in addition to teaching the children writing, Mao Wenlong also carefully taught the children arithmetic. Although it was just a basic question of how much one plus one equals, he also taught it well!

This is obviously because he does not understand Master Mao's history. Xiaoyu asked Li Xiao when Qiankun Kandui Xunli Genzhen was eating. Li Xiao stared at him, dumbfounded by his sister's question. How did I know that gossip is

What's going on?

Li Hao was even more outrageous. He explained to Li Xiao what Heshu Luotu was called. What is the meaning of wearing nine shoes and one, three on the left and seven on the right, two and four as shoulders, six and eight as feet, and five in the center. Li Xiao was stunned.

I was stunned, I didn't expect Mao Wenlong to have such profound knowledge.

It's best not to express opinions on things you don't understand. Li Xiao didn't quite understand the teaching methods of the ancients. Li Xiao told his younger brothers and sisters to study hard, and then he was busy with the modification of firearms.

Until one day, Li Hao and Xiaoyu took Mangui to tell fortunes.

"Master Man, you have purple lines on your palms and peach blossoms in your eyes. You are going to be lucky!"

Li Xiao looked at Li Hao, who was like a little adult, and his jaw dropped to his feet. Why did these words sound so familiar? The old men and women who set up fortune-telling stalls at the entrance of the park seemed to say this.

"Brother, your hall has become dark, and there will be...!" Xiaoyu tilted her little head, and looked at Li Xiao's face with big eyes. The words she said made Li Xiao's head "buzz" and "buzz".

.

If I guessed correctly, the following should be "Young man, I have a talisman here that you can take to ward off disasters. Please give me some money, I mean it!"

"Brother, Xiaoyu has a way to crack it. As long as you...!"

"Mao Wenlong, you bastard. What did you teach my younger brothers and sisters?" Li Xiao's roar could be heard clearly by almost the entire Pi Island.

If you knew about Mao Wenlong's career history, Li Xiao would definitely beat his chest. Because Mr. Mao Wenlong's family conditions were not very good when he was a child, and his main form of entertainment in childhood was to eat everywhere.

Because his family was too poor, Mao Wenlong didn't have enough to eat, so he couldn't afford to go to a private school. He couldn't really understand the Four Books, Five Classics and eight-legged essays. However, his mother was still a cultured person, at least he knew how to read. I held on tight.

Preschool education finally prevented Mr. Mao from becoming illiterate!

Mr. Mao doesn't seem to be the master of ruthless fighting. His skills in fighting and acting are also poor. He can't take exams and can't make trouble. He is useless and is worse than a scholar.

Slowly, the preschool child Mao Wenlong grew up. Since he grew up, he naturally wanted to make a living. Although Mao Wenlong had no future, he did not want to stay at home and grow old. As the saying goes, men are afraid of entering the wrong profession, and women are afraid of marrying the wrong man. Mao Wenlong

It’s a wonderful start for my life and career planning.

In order to make a living, he began to engage in the service industry - fortune telling.

Fortune telling is a technical job, and even if you really don't understand it, you still have to be able to fool it, so Mao Wenlong began to study the hemp physiognomy, fortune telling, Bagua and so on.

In the Ming Dynasty, subjects such as fortune telling, art of war, and astronomy were all miscellaneous subjects, and they were often grouped together. There was also an inexplicable collective name - Yin and Yang studies.

Due to the need to make a living, Mr. Mao usually reads these kinds of miscellaneous books, so although he has never attended a private school, it is not that he has never read books. It is said that he is not only proficient in the theory of military art, but also often uses it in practice - used to brag when chatting

.

Just like this, I kept calculating and boasting until I was thirty years old.
