These words were exactly what everyone thought, and they all agreed happily. It was getting late, and Chen Wanrong could not bear the salt, so he had to give up. That night, Chen Wanrong held a banquet to celebrate Zheng Qing's success.

This incident was really happy. Everyone was very excited. They kept cups and cups until they were over. Qing'e went to Zheng's mansion and did not come back. Zheng Qing had no choice but to talk to Chen Wanrong. Chen Wanrong was extremely happy and praised Zheng Qing well. Of course, he took advantage of himself. He was as happy as a god until the two of them were sleepy and went to bed.

The next day, Chen Wanrong went to take a walk. Today, Chen Wanrong finally found something was wrong. As soon as he left the mansion, he saw people coming and going in front of his mansion, which was very different from before. Chen Wanrong was extremely alert and immediately retreated to the mansion, hid in the dark for a while, and found that several of them seemed to be fine. He swayed in front of the mansion for a long time before leaving.

It was not clear which side of these people were. Chen Wanrong was very excited and finally lured the enemy out, rode on the blue and white porcelain, galloped away. After running for a while, he looked back and saw that the people seemed to have not seen him, and were still swaying in front of the mansion. Chen Wanrong wondered, maybe they were people sent by Shen Que.

When Chen Wanrong thought of Shen Que, he couldn't help but complain. Since the agreement that day, Shen Que has never shown up again, and he doesn't know what he is doing, and he doesn't reveal any news.

After all the resentment, Chen Wanrong had no choice but to take a horse out of the city and run eastward. After a closer look, he found that unlike before, there were many people with good skills among the pedestrians on the road. Chen Wanrong was curious, so he simply pulled the reins, slowed down his steps, and moved forward slowly.

Two stout "passengers" immediately noticed Chen Wanrong's strangeness and leaned towards Chen Wanrong. Chen Wanrong couldn't tell which side they were, and his heart tightened. As he was shocked, three more pedestrians leaned forward and walked straight towards the two men before, and the two men immediately turned around and left.

Later, the three of them saw that the two men did not move, ignored them and continued to "rush". Chen Wanrong guessed that the two men were from the Crescent Sect before, and the three men behind should have been sent by Shen Que. Shen Que actually arranged manpower on his way to the horse. It was probably only a small part of them, so there would be others.

As Chen Wanrong expected, along the way, he always found that someone wanted to be unfavorable to me, and someone rushed over to stop me immediately. Chen Wanrong was both happy and a little puzzled, and obviously mobilized the Crescent Sect. Why didn't Shen Que arrest people?

After thinking about it, I immediately realized that these people from the Crescent Moon Sect are all small characters, and they have limited knowledge and it is useless to seize them. Shen Que did this like telling the Crescent Moon Sect that your actions are under my control. The Crescent Moon Sect either stops or sends more people to deal with Chen Wanrong.

If more people are sent, there will inevitably be someone in charge. So as long as you catch the person in charge, you can force you to ask for more information. Shen Que is indeed old and amazing.

While walking, more than a dozen "peeders" in front suddenly stopped, put their right hand into their arms, and surrounded Chen Wanrong. Chen Wanrong knew that they must be from the Crescent Sect and the general situation was not good, so he pulled the reins and prepared to run back. With the fast pace of blue and white feet, there would be no problem to escape.

At this moment, a sound of thunderous hooves sounded, and a team of Tang army pegasus came. They came to Chen Wanrong, stopped, and shouted to the head officer: "Get out of the way, don't stand on the road, have you heard? No ears!"

There were more than 100 officers and soldiers in this team, who deliberately or unintentionally protected Chen Wanrong in the middle. Although the "passengers" were unwilling to accept it, they looked at the sword unsheathed and the bow was in a row, and the murderous Tang army was helpless and had to get out of the way. Chen Wanrong thought that the arrangement was really thoughtful. At the critical moment, the officers and soldiers arrived. Under the protection of the officers and soldiers, Chen Wanrong ran east for a while, and then drove back to the city.

The officers and soldiers sent Chen Wanrong to the city gate before leaving. From beginning to end, the officers and soldiers did not say a word to Chen Wanrong. Chen Wanrong didn't ask them, and Chen Wanrong simply didn't ask.

When he returned to the mansion, Zheng Qing and Qing'e came up. While eating breakfast, Chen Wanrong listened to Qing'e's report, saying that the girls in the Zheng Mansion liked them so much after smelling the perfume. Zheng Zhou was also happy to smell it, and told the girls that if they found the recipe, they could get 20% of the dividends. They were all in high spirits and rushed to mix perfumes.

Chen Wanrong smiled and said, "Mother-in-law is really the case. It's been a few days since she asked the girl to be a match."

"Don't blame my mother, there are too many things at home. Besides, if Qing'e hadn't brought the perfume over there, my mother wouldn't have believed it all. Now, I believe it without doubt. You can wait and see. It won't take long to get you a lot of recipes." Zheng Qing said confidently.

She is the eldest lady of the Zheng family, so she naturally knows some of the girls. She said she must have it, and Chen Wanrong was also happy.

After breakfast, Chen Wanrong was about to cook salt, but Chen Que rushed over. Chen Wanrong welcomed him into the living room, asked someone to bring tea, and asked him about his purpose: "Mr. Shen, you are not going to the Three Treasures Hall for nothing. Can you tell me your purpose?"

Chen Que did not answer the question, and asked back: "Brother Wanrong, can't I come to you to ask for a cup of tea?"

Chen Wanrong smiled: "Mr. Shen, I believe this, you said, I don't believe it. We have been dealing with each other for so long, don't I understand you? Besides, the prince is decisive in his work. You are the person around the prince, so you won't not learn this advantage, right?"

Haha, Chen Qi nodded and said, "Brother Wanrong, you always have something to say. Okay, I will tell you. I'm here to tell you something. Starting tomorrow, don't let go."

Chen Wanrong asked in surprise: "But there is a clue?"

Chen Qi nodded and said, "Brother Wanrong, you must have known what happened this morning. I guess, these people want to attack you this morning and are destroyed by our people. If you go and go for a walk, you will not be able to protect more people, and I am not sure that you will be able to protect you."

A mystery arose in Chen Wanrong's heart: "Mr. Shen, I'm very strange. It seems that the Crescent Sect doesn't want to kill me. If they want to kill me, there will be a chance this morning."

Chen Que laughed: "Brother Wanrong, you really realized it later. Think about it, the Crescent Sect wants to rebel, what do they need most? It's just money and people. Your soap is sold so well. If they get the recipe, would you get a money tree? If I guess correctly, the Crescent Sect has changed its mind now. They will not kill you, but will capture you alive and force you to tell the recipe for the soap."

This makes sense, and Chen Wanrong agrees. In fact, many people know the production method of soap, but the Crescent School will not believe that Chen Wanrong will tell others such a wonderful method. Even if you tell others, you will definitely keep your hands. Instead of making things difficult for others, it is safer to catch Chen Wanrong.

Understanding this level, Chen Wanrong felt relieved. At least the Crescent Sect will not deal with relatives and friends for the time being: "Mr. Shen, there are many people coming this morning. Why don't you follow the clues and get some information?"

"Do you think I don't want it? It's just impossible." Chen Que explained to Chen Wanrong: "In the past few days, I have sent people to touch the way these people come from. They are just small minions. Even if they catch them all in one go, they will not be able to get much useful information. On the contrary, they will scare away the person behind them. This time, my goal is this person."

Chen Wanrong said worriedly: "Mr. Shen, if you want me to stay at home, aren't you afraid that the person in charge will notice your intentions and escape?"

Chen Que laughed happily: "Brother Wanrong, of course I am worried about anything else, and I am not worried about this at all. Think about it, with the soap recipe, the Crescent Moon Sect is like a huge increase in strength. Even if they pay a price of hundreds or thousands of people, they are willing. Besides, this matter must have alarmed the leader of the Crescent Moon Sect. If it cannot be done, will the life of the principal be better? Therefore, I dare to predict that the principal will be willing to go all out in order to catch you and make a big effort. If what I expected is good, it will be in the last few days."

This also makes sense. Chen Wanrong nodded: "Mr. Shen is still thinking about it. With Master Shen taking care of it, what else can I worry about?"

Chen Zheng once again reminded him: "Brother Wanrong, you can't leave the house no matter what. Even if you have something to go out, you have to bring more people. You can't learn to walk away in the morning and go out alone."

"Okay, I'll listen to you." Chen Wanrong also reminded him: "Mr. Shen, if these evil men arrested my mother-in-law and father-in-law and forced me to go, I have no choice."

Chen Que smiled and said, "Brother Wanrong, don't worry, the iron bucket in Zheng Mansion is like that, there will be no loss."

Chen Wanrong shook his head and said, "Mr. Shen, you only pay attention to Zheng Mansion, this is not OK. You must know that my father-in-law often walks outside."

Chen Que was shocked and stood up suddenly and said, "Brother Wanrong, you reminded me that I will make arrangements now. But don't worry, you won't make any mistakes." Without waiting for Chen Wanrong to speak, he left quickly.

Chen Wanrong was not very worried, but just a reminder. Now the Crescent Sect focuses on Chen Wanrong, so it will not make things difficult for Zheng Jianqiu and the others. Of course, if Chen Wanrong can't be caught, it will be hard to say.

After seeing off Chen Que, Chen Wanrong came to boil the salt. It would be very troublesome to do it alone. Zheng Qing was good to help, but she was busy with perfume. This matter naturally fell on Xiao Shangrong. Chen Wanrong came to Xiao Shangrong's room with perfume, and saw that Xiao Shangrong was not squinting and focused.

Chen Wanrong coughed and asked, "Shang Rong, how worthy is?"

Xiao Shangrong glanced at Chen Wanrong and smiled and said, "Brother, it's early, I just found some tricks."

Chen Wanrong walked over and said, "You don't have to be worthy. If you want money, I'll give it to you."

"No!" Xiao Shangrong refused without thinking: "Brother, how can I earn what you gave me?"

This is too reasonable. As long as people with a little self-esteem would rather make money by themselves than ask for money given by others, even if they are brothers. Of course, there is an exception, that is, a person with talented people who are temporarily down and out, and there are too few such people. Besides, Xiao Shangrong is not such a person.

Chen Wanrong originally wanted him to help, but after hearing this, he changed his mind and encouraged him: "Then you can match well and get a few more. In the future, you won't have to worry about your second uncle and the others."

Xiao Shangrong's face turned red: "Brother, where have you said?" He began to pay attention to perfume again.

Chen Wanrong left the house, closed the door, and came to find Wang Zhongze. Fortunately, Wang Zhongze and Wu Bo were busy refining the essence oil. Zheng Qing's perfume had been successfully prepared, and Wu Daozi and the others also made progress. This essence oil should be produced in large quantities. Chen Wanrong called Wu Bo and asked him to lead someone to start making kettles, build stoves, and prepare to do something big.

It is too idle for so many people to refine essence oil. Uncle Wu and the others have wanted to hear this for a long time. Without saying a word, Uncle Wu sent people to get started.

Chen Wanrong brought Wang Zhongze to the room where he was accused of the scent and said, "Master Wang, I wanted Shang Rong to help, but he was determined to match perfume, so he had to ask you for help."

Wang Zhongze said without saying a word, "English, just give me what you want to do."

Chen Wanrong smiled and said, "I want to boil salt today, so we both can do it. Move the saltpeter here first."

He had no idea about the King of Boiled Nitrogen, so he followed Chen Wanrong to bring saltpeter. In the Tang Dynasty, saltpeter was a medicine. Although there were not many medicine shops in Chang'an, there were many medicine shops in all of them, and they collected four or five hundred kilograms. The two of them ran several times before moving in.

After resting for a while, the two of them fed water, poured it into the pot, and started to raise the heat. When the fire rose, Chen Wanrong put the saltpeter into the pot. Wang Zhongze didn't understand the reason and said in surprise: "Boss, what are you doing? Cooking stones? How easy is this stone to cook?"

Cooking stones? Chen Wanrong thought this statement was too funny and explained: "This is not cooking stones. This is saltpeter, which is easy to melt in hot water."

Wang Zhongze didn't believe it: "No way? It's like it's okay in cold water. Is it different in hot water?" Yan Qing opened her head and stared at the saltpeter in the pot: "The boss, hasn't changed much?"

Saltpeter is actually potassium nitrate, and the preparation of gunpowder depends on potassium nitrate. The solubility of potassium nitrate changes very greatly with the temperature. The solubility of zero degrees is more than 13 grams, about 21 grams ten degrees, about 32 grams twenty degrees twenty degrees, and at eighty degrees, it reaches 169 grams, and at one hundred degrees one reaches an astonishing 246 grams.

It is precisely by using the principle that potassium nitrate has a huge change in solubility that potassium nitrate can be obtained.

Wang Zhongze has no common sense in chemistry, does not understand the meaning of solubility, and it is normal not to believe it. Chen Wanrong can't explain it to him, he can only say that you just wait and see.

As the temperature rose, Chen Wanrong couldn't stop stirring, and the saltpeter in the pot slowly dissolved. Wang Zhongze said in surprise: "It's true, the faster the heat."

Put saltpeter in the pot and stirred for a while, there was a strange smell in the room. Chen Wanrong called Wang Zhong to reduce the heat. Although the solubility of potassium nitrate in hot water is very high, the temperature is too high, which is not bad for people. Now there is no protective facilities, so the temperature can only be controlled at a lower level. The advantage of doing this is that it is little harmful to people, but it reduces efficiency. For health, this is a price that has to be paid.

Keep putting saltpeter into the pot until it doesn’t change much, and Chen Wanrong stops putting saltpeter. At the same time, he doesn’t stir and shake anymore. As long as Wang Zhong keeps low heat and maintains the temperature, it will be done.

After a while, the pot was clarified, and Chen Wanrong carefully scooped the upper layer of liquid into another clean pot. Chen Wanrong and Wang Zhongze worked together to pour the remaining mud and sand into a bucket and put it in a bucket.

The potassium nitrate content in saltpeter ore varies depending on the quality of the ore level. It is very good to have a 10% content. Of course, saltpeter ore also contains other substances that can be soluble in water, but the amount is not too large. The rest is soil, and these things should be disposed of. To deal with it, you have to wait until the temperature drops, so Chen Wanrong poured it into the barrel and put it in the first place.

"Boss, that's all right?" Wang Zhongze couldn't figure it out.

Chen Wanrong smiled and said, "It's early, but it's just started. Now this step is to transfer saltpeter from the mine to the water, and it will be thickened, cooled and crystallized later."

Wang Zhongze said oh and asked, "Boss, should you continue?"

"Yes." Chen Wanrong affirmed, Wang Zhongze poured the water into the pot, Chen Wanrong added some firewood, and the flames in the stove rose again. This time, before Chen Wanrong could speak, Wang Zhongze put the saltpeter ore into the water.

There were three stoves in the house. In order to improve efficiency, Chen Wanrong started working at the same time. It was not until after noon that the saltpeter ore was completely processed. Next, it was time to strengthen the pot. Chen Wanrong and Wang Zhongze put the pot together, then scoop the clarification liquid and then raise the heat.

Gunpowder is not far away, and Chen Wanrong can't help but become excited.
