Genius Doctor Peasant Girl

The power of these firecrackers is judged by the degree of fragmentation of the pork belly.

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

Everyone waited with the heart to watch the excitement, but the results came out very quickly, thinking that the firecrackers made by the master surnamed Lu were the most powerful and could blow up the pork belly to pieces.

As for the other ones, they could barely blow up those pork belly cracks.

Chunfeng carefully checked the ingredients recipe that Master Lu made for firecrackers, and it seemed that there was something more in it compared to the other ingredients. After careful identification, Chunfeng confirmed that it contained something similar to potassium nitrate.

That's right, this thing officially made the important ingredient of black powder, and Chunfeng nodded in satisfaction.

But speaking of it, if you can get ammonium nitrate, the power of the bomb can be doubled.

However, it seems that the method of obtaining ammonium nitrate is not that simple. General potassium nitrate can be used to find the original ore, but ammonium nitrate requires a series of complex extraction and refining.

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

"Well, this official announced that the winner of this time is the owner of the Lu family firecrackers, Lu Youxing!" With the order of the county grandfather, five hundred taels of silver were delivered to Master Lu.

The people present were both envious and jealous, and they were all whispering.

The Master Lu knelt on the ground to thank the magistrate of the county and the king of Yao, but he did not expect that he, a craftsman, would have such a fortune one day.

When the result came out, everyone was dismissed, and Master Lu was invited to the side alone.

When the spring breeze came in, Master Lu was cautiously holding the silver in his arms and happy.

"Lu Youxing! Why don't you come and meet the prince, the princess empress?" The county grandfather followed Chunfeng and the prince and watched the prince come in. The man was still there with his head down, and he shouted doglegs. .

"Ah, Cao Min knocked on the prince and princess!" Lu Youxing was shocked, prince? princess?

When he raised his head to look at the inviter, he immediately knelt on the ground in shock.

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

"Many, thank you, the princess and empress." It was the first time that Lu Youxing saw such a valuable person, and could not help but scared the ranger's legs trembling.

"You don't have to panic. I invited you today to ask where did you get this firecracker recipe?" Chun Feng said kindly, looking at the other party's trembling body.

"This recipe was uploaded by our ancestors, and the younger generation is already the third generation." Lu Youxing said cautiously.

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

"Yes, the generation of the villain's grandfather was originally a foreigner. He had been working in the quarry for a few years, and he accidentally discovered several strange stones, so he made this recipe. Passed to my father. In the first generation, when firecrackers began to be popular a few years ago, my dad took it out and made firecrackers again. Because the little people made firecrackers with the brightest sound, the business was also good. Two years ago, my father passed away. Pass the craftsmanship to the younger ones." Na Lu Youxing lowered his head, as if pouring beans from a bamboo tube, he explained everything clearly.

Although I don't know whether this is true or false, the origin of gunpowder prescriptions is not true.

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

And Hongluan is the person of Molan outside the Guan.

"So, I don't know if you can write your prescription to me?" Chunfeng nodded faintly, looked at the other party's response and said: "Don't worry, I won't let you write in vain, if your prescription is useful , I can reward you five hundred taels of silver, how about?"

The spring breeze has begun to entice it, how most people are willing to reveal their life-saving skills to others, but this is the first priority, it is inevitable that some people will be tempted.

"Really?" Lu Youxing asked, looking up with beaming eyes.

"Really, how can my dignified princess say nothing." Chun Feng nodded earnestly.

"As times, the villain writes!" Lu Youxing thought of so much money, and he wrote.

With this thousand taels of silver, he can set up a good small courtyard, and he can also set up a lot of fertile fields. Once he has land, he can stay at home and become a rich man.

Thinking happily, Lu Youxing almost left a place in his mouth, and finally he could end this poor life.

As soon as Lu Youxing agreed, Chun Feng waved his hand, and someone immediately took up his pen and ink.

Picking up the pen and paper, Lu Youxing quickly wrote a prescription on the paper, put down the pen, turned and respectfully said: "Prince, please look at it."

The servant who was waiting for the pen and ink hurriedly took the written prescription to Chunfeng, and Chunfeng looked at it carefully, and it was almost the same.

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

Lu Youxing kept looking at the expressions of several nobles, fearing that the nobles would ask for his head when he was angry.

Seeing Chun Feng nodded in satisfaction, Lu Youxing was relieved.

"There is one more thing to trouble Master Lu. I don't know, where do you get the materials for making firecrackers, especially this kind of saltpeter?" Chun Feng asked Lu Youxing lightly when he looked at him.

"Saltpeter?" Lu Youxing thought for a while and said: "Oh, the villain knows that this thing was collected on the Black Tiger Mountain twenty miles away. If needed, just send someone in to pick it up."

Lu Youxing is an honest, plus facing such a valuable person, he doesn't dare to be slippery, so he speaks truthfully.

"Heihu Mountain twenty miles away?" Chunfeng repeated, not far away.

"Okay, you can go, but I don't want anyone else to know about the Black Tiger Mountain, do you understand?" said Chaolu Youxing with a warning in Chunfeng's eyes.

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

"The magistrate Laofan is drawing five hundred taels of silver for this person, even if it is on my head." Chunfeng turned his head and said to the magistrate.

"The princess is polite, don't dare to go down!" After the county magistrate responded politely, he bowed out of the room and turned around to fetch the man five hundred taels of silver.

Na Lu Youxing's happy eyes almost narrowed into a line, and he walked with wind at his feet, rushing towards the house quickly.

Time waits for no one. After Lu Youxing left, Chunfeng immediately asked Baili Mochen to send people to Heihushan to mine.

During the whole process, Baili Mochen barely made a sound, watching Chunfeng negotiate with Lu Youxing.

The love in his eyes can't help but deepen, this girl is now more and more like a princess, yes, yes!
