Zhu Hongsan looked at the black guy in his hand. This thing was very heavy, and it weighed three pounds a small piece. Zhu Hongsan looked carefully and found that it was black gunpowder. It seemed that they had compacted the black gunpowder and formed a medicine pillar.

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

Duan Changyou said on the side: "The prince has such a good eye, this is suppressed by gunpowder."

It turned out that when Zhu Hongsan left, he gave Lao Duan Tou an order to experiment with great power. Zhu Hongsan held an experimental mentality, but he didn't expect Lao Duan Tou to take this matter to his heart. You must know that a craftsman mastering a unique secret is a lifelong glory.

When Lao Duan Tou returned to the factory, he organized several masters to set up a public relations team and began to experiment with new formulas of Dawei gunpowder. However, they had never learned modern chemistry and knew any chemical equations. They just used a lot of experiments to bump into the gunpowder. Everything was added to the gunpowder, such as gold, silver, copper and iron, hair, rag heads, etc.

There is a gunpowder master named Zhang in this group. He turned out to be a firecracker shop in Dongguan County. After Feng Ziyong became the county magistrate, he found a reason to take him to the gunpowder factory to work.

Master Zhang found that nothing was as powerful as the current gunpowder. Since the power of the unit weight of gunpowder cannot be increased, it is feasible to increase the amount of gunpowder charge.

Increasing the amount of gunpowder charge means that the volume of gunpowder increases. So what if it is compressed? Unexpectedly, an experiment is really feasible. Gunpowder can be compressed to at most one-third of the total weight, and its power is twice that of the same weight of gunpowder.

Zhu Hongsan heard Lao Duan Tou say, "You are too brave. I wonder if the gunpowder can explode by itself if it is compressed too much?"

Old Duan Tou looked ugly and said, "I didn't know before. After the explosion, we only knew that the maximum compression of gunpowder would reach one-quarter of the total weight, and it would explode if it was too high. One-quarter would be unstable, and it would explode with a fall to the ground. Only one-third would be safe."

Speaking of this, the old Duan Tou spoke in a low tone and said, "We didn't expect that gunpowder could explode on its own. The Master Zhang, who proposed this statement, also died in an explosion."

Zhu Hongsan sighed. It seems that it is terrible to have no basic physics knowledge. Even ordinary junior high school students in later generations know that the greater the pressure, the higher the internal temperature.

Zhu Hongsan asked: "Have you successfully tested now?"

Old Duan Tou said: "It has been successful. The one in the prince's hand is made of three pounds of gunpowder. It is as large as one pound of gunpowder, but it is twice as powerful as three pounds of gunpowder. However, this kind of gunpowder does not need to be ignited with fire, but can only be used as gunpowder."

Zhu Hongsan looked at the black medicine pillar in his hand. Zhu Hongsan knew that it was because it was too dangerous to take it out before. If one was not controlled well, it would explode during the production process. Unexpectedly, these craftsmen were really not afraid of death, so they made it out by themselves.

The principle of ordinary gunpowder explosion is to burn quickly, to put it bluntly, it is burning. Although it also looks like an explosion, you have to put black* gunpowder in an open space and ignite it and will not explode.

However, the principle of modern explosives is to explode. Modern yellow gunpowder will explode even if it is detonated in an open space. This is different from the working principle of black* gunpowder.

Zhu Hongsan read a post in later generations that ordinary black* gunpowder has been compressed and has changed its explosion method and has already exploded. Some people in later generations have calculated that the same volume of compressed black* gunpowder can reach 60% of the power of TNT intense explosives.

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

Lao Duan took everyone to the test site outside the factory. There was a small hole in the middle of the medicine column. Old Duan filled it with ordinary gunpowder, stuffed it into the lead wire to compact it. Then he ignited the fire and ran away.

Ten seconds later, there was a loud bang and the test site was covered with smoke.

When the smoke of gunpowder dissipated, Zhu Hongsan and his men stepped forward and saw a huge bomb crater exploded on the ground. You should know that the medicine column was placed directly on the ground without packaging.

Tie Niu looked around and widened his eyes. After a while, he said, "What a great power. Prince, let's change the fire medicines of muskets and cannons like this."

Zhu Hongsan shook his head and said, "The cannon is OK, but the musket cannot do it. The musket wall is too thin to withstand this power."

Zhu Hongsan thought about it and said that since this kind of gunpowder has been invented, it should be used. Anyway, you don’t have to produce it yourself, and you don’t have to die by yourself.

Thinking of this, Zhu Hongsan said: "Old Duan, you build another factory five miles away from the gunpowder factory to produce this kind of compressed gunpowder, which is only used for artillery use. The original artillery charge stopped production."

After thinking about it, he said to Liu Dali: "Tomorrow you will bring five artillery pieces and do experiments for the gunpowder factory. The gunpowder factory will develop the most suitable charge. You cannot have too much blow-up or no power, do you know?"

Liu Dali and Duan Changyou nodded repeatedly.

Finally, Zhu Hongsan said: "Each family who died in the experiment gave 500 taels of silver, and his sons were sent to the academy of the farm to study."

Zhu Hongsan traveled around the factory for a day today. It was getting late and he also looked at a lot today and had a clear understanding of his own factory.

Zhu Hongsan had a conversation with the three foremen, and encouraged them to work harder and made them work harder for themselves even more desperately, and then took Ma Shaoguang home.

When I got home, it was already dark. I called the butler Zhu Fa at the door and said, "But, go and call my elder brother, I'll wait for him in the lobby."

Back at the lobby, Zhu Hongsan washed his face and just sat down when he saw Zhu Hongyi coming in.

Zhu Hongsan said: "Brother, how about it? You can rest in the past two days."

Zhu Hongyi said: "It's great. I went home and looked at the two little kids. They were almost taller than me. I looked at my daughter again."

Zhu Hongsan smiled and said, "I'll tell you something today. Let's go to Nanhaiwei tomorrow to see how these guys are training."

Zhu Hongyi said: "Okay, I'm tired of staying at home."

Zhu Hongsan continued: "There is another thing. Brother is going to work overtime tonight and tell us about the sugar-making process when we were young. You are responsible for saying it, Ma Shaoguang is responsible for writing it. Try to be more detailed. In a few days, let Mr. Ma take it to Leizhou Prefecture. That place is a paradise for sugar-making."

Zhu Hongyi nodded and led Ma Shaoguang, who was full of bitter faces, to write the sugar-making process.

Zhu Hongsan sat in the lobby for a while, thinking about whom he would go to tonight, so he thought about it and decided to go to the Dong sisters. He hadn't seen Zhu Yu for a long time and missed his daughter a little.

Zhu Hongsan came to the yard of the Dong sisters. The two of them lived together, with a total of five houses and six servants. They were second only to Ma Xiaofang and Ma Ruyan’s aunt and nephew at home.

Before Zhu Hongsan arrived at the door, the Dong sisters knew that the master was coming, so they hurried out of the door and waited in the yard. Zhu Hongsan entered the yard and saw Zhu Yu staggeringly walking towards him, saying a hug from his father.

Zhu Hongsan happily picked up Zhu Yu, kissed her pink face, and said, "I'll sleep here tonight, you sisters and you will serve me together."

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

Zhu Hongsan led his son Zhu Huai and his daughter Zhu Yu into the house. After a while, the wine and food were placed. Zhu Hongsan and the Dong sisters and two children had a rare dinner. They naturally had fun with the twins at night.

The next morning, Zhu Hongsan got up and was about to go to the military camp. When he left the gate, he saw Zhu Hongyi leading a hundred and fifty guard company standing at the door. Zhu Hongsan looked at Ma Shaoguang who was yawning behind him and asked, "Boyu, did you not sleep well last night?"

Ma Shaoguang cursed in his heart: "It would be strange if you can sleep well after copying the recipe for you for a night."

Zhu Hongsan saw Ma Shaoguang's two dark circles and was secretly happy, but said, "Boyu, be careful of your health. Even if the beauty is good, you must be moderate." After saying that, regardless of Ma Shaoguang who was cursing in his heart, he rode a horse and took the guard company to the Nanhai Guard.
