The power of these firecrackers is determined by the degree of fragmentation of the pig's belly.

Everyone was surprised by this approach. What was it to do?

Everyone was waiting with the fun, but they came out soon, thinking that the firecrackers made by the master named Lu were the most powerful and could blow the pork belly to pieces.

As for the others, they could barely break the pork belly into cracks.

Chunfeng carefully checked the recipe for Master Lu's firecrackers. It seemed that there was something more in it than other ingredients. After careful correction, Chunfeng confirmed that it contained something similar to potassium nitrate.

That's right, this thing is an important ingredient in formally making black gunpowder, Chunfeng nodded with satisfaction.

But if you can get ammonium nitrate, the power of this bomb can be increased exponentially.

But it seems that the method of obtaining ammonium nitrate is relatively not that simple. Generally, potassium nitrate can be found in native ores, but ammonium nitrate needs to undergo a series of complex extraction and refining.

However, if potassium nitrate can be refined to a certain purity, it is estimated that the effect of making bombs will be much better.

"Okay, I announced that the boss of the Lu family's firecrackers won this time, Lu Youxing!" With the order of the county magistrate, five hundred taels of silver were sent to Master Lu.

The people present were both envious and jealous, and they were talking about each other for a while.

The Master Lu knelt on the ground and thanked the county magistrate and Yao Wang Qianen. Unexpectedly, he, a craftsman, would have such good luck one day.

As a result, everyone was dismissed, and Master Lu was invited to the side alone.

When the spring breeze entered the door, Master Lu was carefully holding the silver in his arms and enjoying himself.

"Lu Youxing! Why don't you come here to see the prince, princess?" The county magistrate followed Chunfeng and the prince. Seeing that the prince had come in, the man was still there with his head down and he shouted with his legs.

"Ah, Caomin bowed to the prince and the princess!" Lu Youxing was shocked, Princess? Princess?

When he looked up and saw the inviting someone, he immediately knelt on the ground in fright.

"Get up and talk!" Chunfeng raised his hand slightly and said.

"Don't, thank you for the princess." This was the first time Lu Youxing saw such a precious person, and he couldn't help but scare the golfer's legs to shake.

"Don't panic. I invited you here today to ask where did you get the recipe for making firecrackers?" Chunfeng looked at the other party's trembling body and said kindly.

"This prescription was passed down from ancestors, and by the younger generation it was already the third generation." Lu Youxing said carefully.

"The third generation?" Baili Mochen raised his eyebrows. This firecracker has become popular in recent years. How come their family has been passed down for generations?

"Yes, the generation of villain's grandfather was originally a person outside the pass. He had been working in a quarry for a while, and accidentally discovered several strange stones, so he made this prescription. When it was passed on to my father's generation, when firecrackers began to prevail a few years ago, my father took them out to make firecrackers again. Because the sound of firecrackers made by the villain was the brightest, the business was also good. Two years ago, my father passed on his skills to the young man." Lu Youxing lowered his head, and explained all the stories clearly like a bamboo tube pouring beans.

Although I don’t know the truth or falsehood of this statement, there are probably many things outside the origin of the gunpowder prescription.

Because according to Baili Mochen's inference, the gunpowder of the Huns was probably given by Hongluan.

And Hongluan is the man from Molan outside the pass.

"So that's it. I wonder if I can write your prescription to me?" Chunfeng nodded faintly, and looked at him without waiting for the other party to respond and said, "Don't worry, I won't let you write it in vain. If the prescription you wrote is useful, I can reward you with another 500 taels of silver. How about it?"

The spring breeze begins to tempt it. How can ordinary people be willing to reveal their life skills to others? However, this is a priority, and it is inevitable that someone will be moved.

"Really?" Sure enough, Lu Youxing raised his head with his eyes lit up and asked.

"Take it seriously, how can my dignified princess not keep her word?" Chunfeng nodded seriously.

"As soon as a villain wrote!" Lu Youxing thought of so much money, and wrote it in his heart.

With this thousand taels of silver, he can buy a good courtyard and a lot of fertile land. With the land, he just stays at home and becomes a rich man.

Thinking happily, Lu Youxing was almost left with a drooling place, and he could finally end this poor life.

As soon as Lu Youxing agreed, Chunfeng waved his hand and someone immediately took the pen and ink.

Picking up the paper and pen, Lu Youxing quickly wrote a prescription on the paper, putting down the pen and turning around and respectfully said, "Prince, please check it out."

The servant who was serving the pen and ink hurriedly took the written prescription to Chunfeng. Chunfeng looked carefully and found that it was almost the same.

But there is another very important thing, that is, ore, the raw materials for making explosives.

Lu Youxing kept looking at the expressions of the nobles, afraid that the nobles would take their heads when they were angry.

Seeing Chunfeng nodding with satisfaction, Lu Youxing breathed a sigh of relief.

"There is another thing that needs to be troubled by Master Lu. I don't know where the materials you make firecrackers come from, especially this kind of saltpeter?" Chunfeng looked at Lu Youxing and asked lightly.

"Saltpe?" Lu Youxing thought for a while and said, "Oh, the villain knows that this thing is really picked on Heihu Mountain twenty miles away. There are a lot of this thing over there, all over the mountain. If you need it, just send someone in to pick it."

Lu Youxing is an honest person, and he dare not be fooled when facing such a person with a valuable status, so he said truthfully.

"Heihu Mountain twenty miles away?" Chunfeng repeated the sentence, but it was not far away.

"Okay, you can leave, but I don't want anyone else to know about Heihu Mountain, do you understand?" Chao Lu Youxing, who had a warning in Chunfeng's eyes, said.

"Yes, yes, the villain understands." Lu Youxing was not too stupid, so he immediately bowed and responded.

"I'm sorry, the county magistrate is withdrawing five hundred taels of silver for this man, even if it's on my head." Chunfeng turned his head and said to the county magistrate.

"You are polite, the princess dare not!" After responding politely, the county magistrate bowed and pushed out of the room, turned around and fed the man five hundred taels of silver.

Na Lu Youqing's eyes were almost narrowed into a line, and he ran towards his house quickly with the wind under his feet.

Time waited for no one. After Lu Youxing left, Chunfeng immediately asked Baili Mochen to send someone to Heihu Mountain to mining.

During the whole process, Baili Mochen almost made no sound, watching Chunfeng negotiate with Lu Youxing.
