Nitrocellulose is known in Europe as fire cotton, and this thing was accidentally sprayed by 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 say it's a rag)

This kind of thing is actually a kind of smokeless gunpowder, and with this thing, Li Xiao planned to drum it out and order ammunition. That is, the kind of bullet with primer in later generations, but the current processing technology is too rough. There was no machinery to process the tightly closed chamber of the gun, and even Li Xiao couldn't even get out the alloy steel used in the firearm.

This involves the knowledge of materials, if Li Xiao still understands some firearms. Materials science, a discipline that requires special training, Li Xiao has no choice. In fact, Yu Lao's phosphorus steel has been a big surprise to Li Xiao. If he tinkered with it himself, he wouldn't even be able to drum up phosphorus steel. It is necessary to know that the proportion of phosphorus in phosphorus steel is very important, adding more will seriously damage the performance of steel, adding less and not meeting the requirements, and the phosphorus steel of the old fisher does not know how many years of experience of craftsmen and households.

The so-called guns in these years are all breech guns. A breech charge that fires a metal ball projectile.

Projectiles are usually lead bullets, with a small amount of steel or iron balls. A lot of the time, it's all about what's going on. But for the time being, I haven't heard of anyone who is rich enough to use gold and silver beads.

Because of the shoddy construction of the projectile, many times the projectile is not actually fired after firing. The soldiers, on the other hand, did not know if their bullets had been fired. It is said that there is a record in Europe for ten projectiles being stuffed into the barrel of a gun!

The biggest weakness of the breech gun is actually the problem of the rate of fire. The arquebus, in particular, was simply outrageously slow in rate of fire. Now the problem that Li Xiao has solved is to first increase the rate of fire of firearms, so as to improve the lethality of musketeers on the battlefield and the ability to fight cavalry.

"Clamp a piece of flint in the jaws of the hammer, make another anvil on the side of the fire hole, and when shooting, pull the trigger, and under the action of the spring, hit the flint heavily on the side of the fire door, sparks appear, and ignite the gunpowder." Li Xiao kept drawing on the drawings, because the painting technique was really not good. The fisherman and Dao Fuyou heard and understood what Li Xiao said, but they couldn't understand what this thing was drawing.

"That's it! All right! We get it! Li Xiao was once again invited out by the two old guys.

Li Xiao, a guy who only understands theory and has almost zero hands-on ability, can just give off-site guidance. As for the actual hands-on, it's still two old guys to do it.

In the distance, there was a loud sound of reading from the new school, and the teaching materials were enlightenment readings that the fifth master got from Hebei. Li Xiao didn't understand much after reading it for a long time, it was all awkward Chinese. There are a lot of eight-strand texts, and Li Xiao knows every word in it. But if it's really connected, Li Xiao won't be able to understand it. Combined, those words are a different language. Li Xiao was very worried that Mao Wenlong taught these children to be nerds.

In Mao Wenlong's words, you are also a reader?

However, this also happens to be in line with Li Xiao's life experience, a young man from a poor countryside. It would be suspicious if you even knew such a high-end product as Baguwen.

Li Xiao's worries did not arise because Mao Wenlong was not only teaching children to write. He also carefully taught the children arithmetic, although it was only a basic problem of how many plus one equals. But it is also taught in a good way!

This is obviously not understanding the history of Lord Mao, Xiaoyu asked Li Xiao Qiankun Kan Dui Xun when he was away from Gen Zhen when he was eating. Li Xiao stared at him with wide eyes, stunned by his sister's question. Where does Lao Tzu know what gossip is all about?

Li Hao was even more outrageous, explaining to Li Xiao what is called Heshu Luotu. What wears nine shoes one, three on the left and seven on the right, two or four for the shoulder, six or eight for the foot, and five in the center. frightened Li Xiao for a moment, but he didn't expect Mao Wenlong to have such profound knowledge.

It's better not to give an opinion on something you don't understand. Li Xiao also didn't understand the teaching methods of the ancients. Li Xiao told his younger brothers and sisters to study hard, and they were busy with the transformation of firearms.

Until one day, Li Hao and Xiaoyu pulled Man Gui to tell fortunes.

"Master Man, your palm face is purple and your eyes are peach blossoms. You're going to have peach blossom luck! ”

Li Xiao looked at Li Hao, who was like a little adult, and his chin was about to fall on the surface of his feet. This sounds so familiar, and the old men and ladies who set up fortune tellers at the entrance of the park seem to say so.

"Big brother, your Yin Tang is black, there will be ...... in the near future!" Xiao Yu tilted her little head and looked at Li Xiao's face with big eyes. The words that came out made Li Xiao's head "buzz" and "buzz".

If you are not mistaken, the following should be: "Young man, I have a talisman here that you can take to avoid disaster." You give some money, meaning! ”

"Big brother, Xiaoyu has a way to crack it. As long as you ......! ”

"Mao Wenlong, you it. What you taught my brothers and sisters what they were! Li Xiao's roar was heard clearly by almost the entire Phi Island.

If you understand the history of Mao Wenlong's succession, Li Xiao will definitely beat his chest. Because Mr. Mao Wenlong's family conditions were not very good when he was a child, the main entertainment method in his childhood was to eat everywhere.

Because his family was too poor, Mao Wenlong couldn't eat enough, so he naturally couldn't afford to go to private school, and he couldn't understand the Four Books and Five Classics and those eight-strand texts. But his wife is still a cultural person, at least he knows words. The old lady grasped preschool education, and finally did not let Master Mao become illiterate!

Master Mao doesn't seem to be a ruthless master, and his kung fu is almost good at fighting and sprinkling, he can't take exams, and he can't make trouble, so it's useless, worse than a scholar.

Slowly, Mao Wenlong, a preschool child, has grown up, and since he has grown up, he naturally has to make a living. Although Mao Wenlong has no interest, he refuses to stay at home and gnaw at the old. As the saying goes, men are afraid of entering the wrong industry, and women are afraid of marrying the wrong man. Mao Wenlong made a very wonderful start for his life and career planning.

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

Fortune telling is a technical job, even if you really don't understand, you have to be able to really fool, so Mao Wenlong began to study Mai physiognomy, word measurement, gossip and so on.

In the Ming Dynasty, fortune-telling, the art of war, astronomy and other disciplines are all miscellaneous, and they are often piled up, and there is also an inexplicable collective name - Yin and Yang.

Forced to make a living, Mr. Mao usually reads most of these miscellaneous books, so although he has never gone to private school, it is not that he has never read books. He is said to have mastered the theory of the art of war, and often used it in practice – bragging in conversation.

Just counted all the way, blew all the way, and mixed until the age of thirty.

Until his uncle Shen Guangzuo made his career and became a political envoy in Shandong. Mao Wenlong came to Liaodong to be an official!
