Chapter 48 Short-sighted

The temperature rose and the water vapor rose, and the smell was not very pleasant. Chen Wanrong added some firewood to the stove cave and retreated with Wang Zhongze. Wang Zhongze was loyal to his duties and asked with some concern: "Our family, no one can watch it, can it work?"

Chen Wanrong reminded him: "Don't worry. After a while, just go in and take a look, don't be there forever. In this way, people will feel better and have done their jobs."

This was a good compromise, and Wang Zhongze had nothing to say. However, curiosity hit his heart again and asked, "Boss, what's the use of you doing this?"

Chen Wanrong was very relieved and said to him, "Yesterday, I went to the prince's place and occasionally thought that I could build a weapon to attack the city. This is part of it."

Wang Zhongze looked at Chen Wanrong for a while and almost laughed: "Boss, can you make weapons? I didn't see it." As soon as he said that, he realized something was wrong and hurriedly said: "Boss, I have nothing else to say."

It is normal for him to believe it. Chen Wanrong smiled and said, "It's okay, don't talk about you, many people don't believe it. You will know when I create it." Facts are better than words, and there is no need to spend so much verbal talk.

Wang Zhongze stopped talking. After a while, the two went in and saw that there was much less water in the pot. Wang Zhongze asked, "Do you want to add water?"

To enrich the water, how can we add water? Chen Wanrong waved his hand and said, "No. It's almost done, let's put it aside and put the rest on and cook it."

Wang Zhongze only followed Chen Wanrong's horse. The two worked together to put the remaining potassium nitrate solution into the pot and heated it. Throw some firewood, and Chen Wanrong pulled Wang Zhongze out of the house.

The two of them worked very hard until the evening. The temperature dropped and potassium nitrate began to precipitate. Looking at the white crystals, Wang Zhong was surprised and pointed to the pot. He couldn't speak for a long time: "Boss, look, there is something strange in the water."

Chen Wanrong did too much precipitation experiment, not surprised at all, and smiled and said, "This is normal. Tomorrow, it should be almost done. You just need to dry it and you can use gunpowder."

Wang Zhongze couldn't calm down. He stood by the pot and looked at it for a while before he followed Chen Wanrong. The next day, Chen Wanrong did not go to take a walk in the horse according to Chen Que's request. He slept a long time ago, until Zheng Qing brought him breakfast, and then got up. With Zheng Qing's help, Chen Wanrong got up, and ate breakfast while chatting with Zheng Qing.

After eating breakfast, I went to inspect it first. Sima Chengzhen and his friends had made progress in the perfume preparation, and they were all very happy. Wu Daozi put down the perfume preparation and began to design the packaging. Wu Daozi worked for Chen Wanrong and did his best. It took a day to design a packaging, and Chen Wanrong was very satisfied.

Under the command of Wu Bo, the essence oil was refining in an orderly manner. Zheng Qing would also conduct inspections and guidance. Chen Wanrong was relieved that he could devote himself to the gunpowder.

What surprised Chen Wanrong was that there was no reaction from the Military Arts Supervision Office, and he didn't know what the result of their argument was. Chen Wanrong could not influence them on the Military Arts Supervision Office, just thought about it.

When I arrived at the nitrogen-boiled room, I saw Wang Zhongze had been there long ago, sticking like a wooden stake, staring at the pot of potassium nitrate crystals in the pot, and I didn't even know how to turn my eyes. Chen Wanrong smiled: "Master Wang, is there any ingots inside?"

This is a joke, but Wang Zhongze still felt embarrassed and blushed: "Boss, this thing is so amazing. Yesterday I looked water, but today I was so white."

Potassium nitrate dissolves in water, and when the temperature drops, it will naturally precipitate. Chen Wanrong smiled and explained to him: "Master Wang, some owners cannot see it, which does not mean that it does not exist. This thing is transferred from saltpeter ore to water. Once we cook it, it will appear after it becomes cold." The word "Cook" means thickening. If it is based on professional knowledge, he will definitely be filled with clouds and fog.

I don’t know if Wang Zhongze really understands or fakes, and there was a long list of oh sounds, and no longer expresses them. Chen Wanrong knew that he had not yet recovered the taste, and no longer explained. He ordered the two of them to put the solid in the pot into the bucket, carried it outside the house, spread the linen on the smooth ground, and then poured potassium nitrate on it and spread it flat.

Looking at the sky, the sun is good, today should be a good weather, and it is just right to dry potassium nitrate.

Chen Wanrong and Wang Zhongze were not very disturbed, but there were too many potassium nitrate, which was dozens of kilograms. It was spread on the ground and was still very eye-catching. The news spread like the wind. Zheng Qing, Sima Chengzhen, Wu Daozi, Wang Han, Xiao Shangrong, Wu Bo and others all rushed to see the story, and pointed at the potassium nitrate, and discussed it.

Sima Chengzhen showed his valuable qualities that he knew in everything: "My friend, what is this? What's the use?"

This is what everyone thought, and Chen Wanrong couldn't answer either: "This is potassium nitrate, which is extracted from saltpeter and can be used to make gunpowder."

"Can saltpeter extract this thing?" Sima Chengzhen was a little disbelief.

Chen Wanrong smiled and said, "Master, this is true. The process of using saltpeter to make potassium nitrate is called boiling nitride. A very simple method is to add saltpeter to boil it in hot water, stirring it while cooking, so that the potassium nitrate can be dissolved in water. Almost stop stirring and shake it. After it is clarified, transfer the clarification liquid away, and then boil the clarification liquid for a while and cool it to get potassium nitrate." He knew that he would ask clearly, so Chen Wanrong said it first.

Chen Wanrong used saltpeter, and if it was nitroso soil, it would be more troublesome and needed to use wood ash.

Sima Chengzhen was amazed: "What a wonderful idea! What is gunpowder? How to make it?"

Chen Wanrong smiled and said, "I can do it after this. Gunpowder is a good thing that can make weapons. If it is put in a jar and seals the hole, it will explode if it is ignited at once."

As soon as he finished speaking, Wang Han asked, "Explosion? What is that?"

Gunpowder was still in its infancy in the Tang Dynasty, and the word explosion was very new to the Tang people. Chen Wanrong was stunned for a moment and thought for a while and said, "When I prepare the gunpowder and demonstrate it to you, you will know what the explosion is."

"Okay, I'm waiting to open my eyes." Sima Chengzhen was very excited about this promise.

Chen Wanrong had no choice but to say that Sima Chengzhen and the others repeatedly told Chen Wanrong to call them during the demonstration before leaving.

There is no need to keep the potassium nitrate drying, Chen Wanrong can do other things. He called Wang Zhongze, and the two of them treated the sulfur and charcoal. After a while, the charcoal powder was enough, so he could make a lot of it. Zheng Qing was curious and followed Chen Wanrong to take action. If she didn't go to inspect, Chen Wanrong could only let her do it.

After finishing this, I looked at the potassium nitrate. It was almost done. Chen Wanrong grabbed a handful of it and kept it away. He arranged the sulfur and charcoal in the ratio of 75 parts of potassium nitrate, 10 parts of sulfur and 15 parts of charcoal. This is the formula of military black gunpowder, which is very powerful.

After mixing evenly, Chen Wanrong was very excited and wanted to try it. He took out the fire and broke it, lit a piece of linen, wrapped it on the stick, and stretched it over. With a sneer, a ball of fire appeared, and a ball of thick smoke, Wei Weiwei's wonder. Zheng Qing and Wang Zhong were shocked, screamed, and jumped far away like conditioned reflex, their eyes widened, and they looked at the place where the gunpowder was set, and a mark was painted black.

There was a strange smell in the air. Chen Wanrong sniffed it and walked over to take a look. The ground was burning black and dark. When he touched it with his hands, it was very hot. He smiled and said, "Success! Success!" Although Chen Wanrong knew gunpowder very well, he still couldn't hide his joy.

Wang Zhongze patted his chest and was a little scared: "Boss, you are really scary, my heart is pounding."

Chen Wanrong laughed and was extremely happy: "Master Wang, is this scaring you? If it explodes, you will probably be so scared that you will sit on the ground."

"No way?" Zheng Qing was a little unbelievable.

Chen Wanrong joked: "Will it be? You will know then. I was scared. What should I say? Should I make a bet?"

"Who is betting on you?" Zheng Qing was unsure and didn't do such unsure things.

After a while, the potassium nitrate was dried up. Chen Wanrong took Zheng Qing and Wang Zhong to collect the potassium nitrate. Then he came to deal with the waste residue and mother liquor. The mother liquor also contained potassium nitrate, but Chen Wanrong decided to throw it away. The reason was very simple. If the court wanted to produce artillery, the production of gunpowder would not be here, and the court would arrange a special place.

The three of them took out the waste residue and mother liquor and dug a hole to bury it.

After all this, it was already past noon. Chen Wanrong took a break and decided to add gunpowder. Chen Wanrong was responsible for the deployment, and Wang Zhongze and Zheng Qing fought to help deal with sulfur and charcoal. This matter was too novel. Zheng Qing was so tired that her pretty face was covered with crystal sweat, and she was unwilling to rest.

After getting nearly a dozen kilograms of gunpowder, Chen Wanrong thought that he should make a fuse. If there is no fuse, this detonation will be a problem. With the conditions of the Tang Dynasty, the fuse cannot be done in a regular manner like the modern fuse. Chen Wanrong's requirements are not high, as long as it can detonate, it will be done.

To meet this requirement, it is difficult for Chen Wanrong to soak the cotton thread in oil, put it in gunpowder and drag it, and a lot of gunpowder will be stained on the cotton thread. Then dry the cotton thread and it will be made.

There is a problem. Chen Wanrong couldn't help but frown. Zheng Qing knew Chen Wanrong very well and hurriedly asked: "Is there any problem?"

Chen Wanrong nodded and said, "Yes! I'm the fuse. The biggest problem is that it's easy to get back on the trend, and things need to be wrapped outside."

"This is simple!" Zheng Qing didn't even think about it and came up with an idea: "Isn't the oil curtain waterproof? Tourists should bring the oil curtain, and it's okay to rain."

This idea is good. I reminded the dreamer with a word. Chen Wanrong laughed and said, "What a good idea. I just don't know if those who make oil curtains will sell their formula?" Chen Wanrong also knew some anti-humidifiers, but they were not able to be made in the Tang Dynasty.

Zheng Qing smiled and said, "They may not necessarily sell the formula. However, as long as you pay for the money to buy the match they have, there will be no problem."

"That's it." Chen Wanrong was very happy and called Niu Shangxin and asked him to buy some anti-humidifiers. Niu Shangxin received the order and went to handle it himself.

When the cotton thread was dry, Chen Wanrong, Zheng Qing and Wang Zhongze together, weaved the cotton threads like braids. After braiding, wrap them with cloth strips, finally brush them with moisture-proof agent and dry them, and the original fuse was made.

After all this, it was already dark. However, Chen Wanrong was more interested and decided to try the fuse if it was easy to use. Sima Chengzhen and the others were also curious and agreed, so Chen Wanrong led dozens of people from the mansion to start experimenting with the fuse.

Tied the fuse to the tree, Chen Wanrong held a firewood with fire, and a little on the fuse, and heard a constant sound of hissing sound. The fire rope kept spewing sparks, and blue smoke came out, and the air was filled with a pungent smell.

This is simply a spectacle. No one has ever seen so many people except Chen Wanrong. They all opened their mouths wide and even forgot to exclaim. It was not until the fuse was ignited that everyone screamed, and the screams were heard, which was particularly loud at night.

"It's so wonderful, so wonderful!" Sima Chengzhen said a few wonders, and then stopped, but the look of surprise on his face was still there, and he didn't know when he would retreat.

"I really didn't expect that there was such a wonderful thing in the world!" Wu Daozi praised and slapped his forehead: "I want to make a painting and record what happened today!"

Wang Han agreed very much: "It should be right!"

Amid the praise of everyone, Chen Wanrong took off the fuse and saw that it was all burned, leaving only an empty shell. The shell also burned many holes, and it was still hot in his hand. Chen Wanrong could not feel it at all. This stupid method was useful, which was so happy.

Everyone was in a good mood and excited, so they surrounded Chen Wanrong for advice. Chen Wanrong was in a good mood and answered questions. They left until everyone was over, and they went to bed.

The next day, Chen Wanrong had breakfast and thought that he had a fuse, so he should verify the power of gunpowder. Although he used military formula, the purity of potassium nitrate produced now cannot be close to 100% and contains a lot of impurities. It is estimated that it is only about 90% purity, so it is necessary to verify it.

It is not difficult to verify the power of gunpowder, just explode it once. If you want to explode the gunpowder, even if there is no shell, it will be difficult for Chen Wanrong to do so. There are too many methods.

I had a certain idea and was about to implement it, but I saw Niu Shangrong coming in: "Boss, someone is looking for you."

"Who? Lord Shen?" Chen Wanrong's face was full of joy.

Niu Shangxin replied: "One surname is Ye and the other surname is Zhang."

"Submit Ye? Zhang? Who is this?" In Chen Wanrong's impression, he didn't know the man named Ye, and he was confused all of a sudden. He quickly walked out of the house and saw two people from afar. One was an old man with white hair and hair, and the other was a middle-aged man. He looked very familiar. When he looked closely, he found that it was no one else, but Zhang Deming.

Since we parted in Luojiadian, we have not seen Zhang Deming for a long time. When Chen Wanrong saw it, he was very happy and trotted to meet him. He shouted from afar: "Master Zhang, why are you here now? I miss you so much!"

Zhang Deming was also happy to see Chen Wanrong. The two of them hugged each other and pounded each other on their backs, looked at each other for a while, laughed loudly, and were extremely happy.

Before Chen Wanrong asked, Zhang Deming smiled and said, "Brother Chen, you have been together for many days. You have made a fortune. From Luojiadian to Ning County, from Ning County to Chang'an, you will be promoted step by step!"

Chen Wanrong teased: "Not you are as powerful as you? You will arrive in Chang'an in one go and reach the sky in one step! Is this Master Ye, right?"

Zhang Deming smiled and introduced: "Master, this is Brother Chen. Brother Chen, this is Master."

Chen Wanrong hurriedly greeted him: "Chen Wanrong has met Master Ye." Chen Wanrong was so fond of Ye Tianheng. He was well-known for his character and skills. He had long wanted to meet him, but he had no chance. It was really a pleasure to meet him today. He said this very sincerely.

Ye Tianheng knew a lot about Chen Wanrong, and admired his wonderful ideas very much. He smiled and replied with a smile, very kind: "Ye Tianheng has met my friend. My friend has helped me a lot. I have long wanted to see you, but I have never had a chance. I will meet you today, so I can comfort my life!" With joy on his face, he held Chen Wanrong's hand and patted it lightly on the back of his hand, which was so excited that he couldn't say.

It can be said that the two of them had been having sex for a long time, Chen Wanrong took Ye Tianheng's hand and said, "Master Ye, serve tea in the house."

Ye Tianheng said ok and followed Chen Wanrong into the house. Chen Wanrong asked the two to sit down, and Zheng Qing brought tea. Chen Wanrong introduced the two to the two again. Ye Tianheng and Zhang Deming congratulated each other and praised them.

Chen Wanrong was very interested today. After a brief greeting, he smiled and said, "Master Ye, you two are rarely here once. We must linger well today."

Zhang Deming looked at Chen Wanrong and felt a little embarrassed. Ye Tianheng couldn't help but shook his hand, sighed, and said, "My friend Chen, Ye has something to say, but he is ashamed to speak."

Chen Wanrong felt something was wrong and smiled: "Master Ye, what's the matter?"

Ye Tianheng was stunned for a moment and then said, "My friend, I'm not sure about the artillery you mentioned. Our military weapon supervisor has studied the matter of the artillery and thinks it is not feasible."

The artillery has long been proven by history, and the military weapon surveillance failed to pass. Chen Wanrong was already full of confidence and suddenly fell into an ice cellar. He asked, "Master Ye, where do you start?"
