Zhu Hongsan looked at the black guy in his hand, this thing is very heavy, and a small piece weighs three catties. Zhu Hongsan took a closer look at the black * gunpowder, it seems that they compacted the black * gunpowder and formed a column of medicine.

Zhu Hongsan asked: "Old Duan, is this suppressed by black * gunpowder?" ”

Duan Changyou said on the side: "The prince has good eyesight, this is what gunpowder suppresses." ”

It turned out that when Zhu Hongsan was leaving, he gave Lao Duantou an order to experiment with high-power gunpowder. Zhu Hongsan had an experimental mentality, but he didn't expect Lao Duantou to really take this matter to heart. You must know that it is the honor of a lifetime for a craftsman to master a unique secret book.

When Lao Duantou returned to the factory, he organized several masters to set up a public relations team and began to experiment with new formulas of high-power gunpowder. But they didn't study modern chemistry, they knew what chemical equations were there, they just bumped into them through a lot of experiments. Everything was added to gunpowder, gold, silver, copper, iron, hair, rags, and so on.

There was a gunpowder master surnamed Zhang in this group, who was originally a firecracker shop in Dongguan County, and found a reason to get him to work in a gunpowder factory after Feng Ziyong became a county magistrate.

Master Zhang found that nothing added was as powerful as gunpowder now. Since it is not possible to increase the power of the unit weight of gunpowder, it must be feasible to increase the charge of gunpowder.

Increasing the gunpowder charge means that the volume of gunpowder increases, so what if it is compressed? Unexpectedly, an experiment was really feasible, and the gunpowder could be compressed to one-third of the total weight at most, twice as powerful as gunpowder of the same weight.

Zhu Hongsan heard what the old Duan said, and said: "You guys are too bold, don't you know if the gunpowder can explode by itself when it is compressed?" ”

Lao Duantou's face was ugly, and he said: "I didn't know before, but after the explosion, we learned that the gunpowder compression is up to a quarter of the total weight, and it will explode at most." Even a quarter of it is unstable, and it can explode when it falls to the ground. Only one-third are safe. ”

Speaking of this, the old Duan Tou said in a very low tone, "We didn't expect the gunpowder to explode on its own, and the Master Zhang who put forward this theory also died in an explosion. ”

Zhu Hongsan sighed, it seems that it is terrible to have no basic knowledge of physics. Even the average junior high school student in later generations knows that the greater the pressure, the higher the internal temperature.

Zhu Hongsan asked, "Is your experiment successful now?" ”

Old Duan Tou said: "It has been successful, the one in the prince's hand is made of three catties of gunpowder, the volume is as big as one catty of gunpowder, but the power is twice as large as three catties of gunpowder." However, this gunpowder does not need to be ignited with fire, and can only be used as gunpowder for ignition. ”

Zhu Hongsan looked at the black medicine column in his hand, this principle Zhu Hongsan knew that he hadn't taken it out before because it was too dangerous, and a bad control could explode in the production process. I didn't expect that these craftsmen were really not afraid of death, and they made it up themselves.

The principle of ordinary gunpowder explosion is rapid combustion, to put it bluntly, it is combustion. Although it looks like an explosion, you have to put black* powder in an open space and ignite it without exploding.

However, the principle of modern explosives is deflagration, and modern yellow gunpowder will explode even if it is detonated in open space, which is different from the working principle of black gunpowder.

Zhu Hongsan saw a post in later generations, ordinary black * gunpowder has been compressed, has changed the explosion method, it is already deflagration, some people in later generations have calculated, the same volume of compressed black * gunpowder can reach 60% of the power of TNT high explosives.

Zhu Hongsan said: "Let's test this new gunpowder." ”

Lao Duantou led everyone to the test site outside the factory. There was a small hole in the middle of this medicine column, and Old Man Duan filled it with ordinary gunpowder and stuffed it with a lead wire to compact. Then the ignition ran away.

Ten seconds later, there was a loud bang, and the test site was enveloped in smoke.

When the smoke cleared, Zhu Hongsan and his people stepped forward to take a look, and a huge crater exploded on the ground. You must know that the medicine column was placed on the ground without packaging.

Tie Niu's eyes widened when he saw it, and after a long while, he said, "It's so powerful." Lord, let's replace the musket and artillery firing medicine with this. ”

Zhu Hongsan shook his head and said, "The artillery is okay, but the musket is not, the wall of the musket is too thin to withstand this kind of power." ”

Zhu Hongsan thought about it, since this gunpowder has been invented, let's use it, anyway, there is no need to produce it by itself, and the dead do not have to die by themselves.

Thinking of this, Zhu Hongsan said: "Old Duan, you can build another factory five miles next to the gunpowder factory to specialize in the production of this kind of compressed gunpowder, which is only used for artillery use. The production of the original artillery charge was discontinued. ”

After thinking about it, he said to Liu Dali: "Tomorrow you bring five artillery pieces and do experiments for the gunpowder factory, the gunpowder factory will develop the most suitable charge, and you can't have more explosive chambers, and you can't have less power, you know?" ”

Liu Dali and Duan Changyou nodded again and again.

In the end, Zhu Hongsan said: "The people who died in the experiment were given 500 taels of silver to each family, and those who had sons were sent to study in the academy of the farm. ”

Zhu Hongsan went around the factory for a day today, and when he saw that it was getting late, he also saw a lot today, and he had a clear understanding of his factory.

Zhu Hongsan talked to the three foremen, encouraged them, made them work harder for themselves, and then took Ma Shaoguang home.

When I got home, it was already dark, so I called the housekeeper Zhu Fa at the door and said, "Housekeeper, you go and call my eldest brother, and I will wait for him in the lobby." ”

Back in the lobby, Zhu Hongsan washed his face, and as soon as he sat down, he saw Zhu Hongyi coming in.

Zhu Hongsan said: "Big brother, how is it?" It's a good rest for the past two days. ”

Zhu Hongyi said: "It's good, I went home and looked at the two little cubs, who are almost as tall as me." I looked at my daughter again. ”

Zhu Hongsan smiled and said, "Call the eldest brother today to tell you something, tomorrow we will go to Nanhaiwei to see how these guys are training." ”

Zhu Hongyi said: "Okay, it just so happens that I'm tired of staying at home." ”

Zhu Hongsan continued: "There is one more thing, the eldest brother is going to work overtime tonight, and tell me the process of making sugar when we were children." You are responsible for speaking, and Ma Shaoguang is responsible for writing. Be as detailed as possible, and let Mr. Martha take it to Leizhou Mansion in a few days, which is a paradise for sugar making. ”

Zhu Hongyi nodded, and led Ma Shaoguang, who was full of bitterness, to write about the sugar making process.

Zhu Hongsan sat in the lobby for a while, thinking about who he was going to sleep with tonight, thinking about it, let's go to the Dong sisters, I haven't seen Zhu Yu for a long time, and I miss this daughter a little.

Zhu Hongsan came to the courtyard of the Dong sisters, the two sisters lived together, a total of five houses, six servants, second only to Ma Xiaofang and Ma Ruyan's aunt and nephew in the family.

Before Zhu Hongsan arrived at the door, the Dong sisters knew that the master was coming, and hurriedly went out of the door to wait in the courtyard.

Zhu Hongsan happily picked up Zhu Yu, kissed her pink face, and said, "I'm sleeping with you tonight, and you two sisters will serve me together." ”

The Dong family sisters were overjoyed when they heard this, and how long had they been waiting for this sentence. The Dong sisters immediately took someone down to make arrangements.

Zhu Hongsan led his son Zhu Huai and daughter Zhu Yu into the house, and after a while, the kung fu wine and food were put on the table, and Zhu Hongsan, the Dong family sisters and the two children had a rare dinner. Naturally have fun with the twins at night.

The next morning, Zhu Hongsan got up and was about to go to the barracks, and when he went out of the gate, he saw that Zhu Hongyi had already led a hundred and fifty guard companies standing at the door, Zhu Hongsan looked at Ma Shaoguang who was yawning behind him, and asked, "Boyu, didn't you sleep well last night?" ”

Ma Shaoguang scolded in his heart: "I copied the recipe for you all night, it's strange that you can sleep well." ”

Zhu Hongsan saw Ma Shaoguang's two dark circles, and he was secretly happy in his heart, but he said: "Boyu, pay attention to your body." Even if the beauty is good, it should be moderate. After speaking, Ma Shaoguang, who was secretly scolding in his heart, rode on a horse and rushed to Nanhaiwei with the guard company.

From Zhangjiazhuang to Nanhaiwei fifteen-mile road, the land along the road has been taken by Zhu Hongsan, and now Zhu Hongsan is said to be a large landowner in Guangdong, and the land under his name is not more than 200,000 mu. However, these lands are reserved for displaced people, and next year when the number of displaced people increases, all these places will be planted with potatoes. This kind of thing has a high yield, and it doesn't pick the ground, so it's really a good thing to fill your stomach.
