After the Eighteen-Line Map appeared, no one made progress. The reason why we were able to draw twenty-line maps was because humans had new tools and computers, and two mathematical enthusiasts used computer technology to draw twenty-line maps.

The map is beautiful and generous, with a clever layout, which is incredible. Wu Jing's talent and vision are superior. He can see at a glance that the map has reached the realm of heaven and man, and manpower should be poor, so he said such surprising words.

Chen Wanrong once again learned about Wu Jing's power, laughed and praised: "Mr. Wu has been too rewarded. As long as he is willing to think about people, he will sometimes do things in the realm of heaven and man, I will get it occasionally and dare not catch the eyes of the teacher."

Be careful in front of a great scholar like Wu Jing, who has strong insight, and if you are not good, you will be exposed. Chen Wanrong has to shamelessly say that he is his credit.

Otherwise, I would just tell him that this is drawn by a computer. With Wu Jing's talent, he would definitely ask what a computer is. If one question is followed by another, there will inevitably be a problem. It would be better to hold on like this.

Huang Boming and Wu Jing bowed to Chen Wanrong together and said, "Brother Wanrong is a talented person, I have seen it, and I admire you!" Huang Boming originally had a little contempt for Chen Wanrong, but now he is convinced, and he said this very sincerely.

Chen Wanrong hurriedly replied, "The two gentlemen have been awarded too much. I just got it by chance. I dare not be the two gentlemen's praise."

Wu Jing looked at Chen Wanrong and exclaimed: "Brother Wanrong is in the fields, but he has such a talent. If Wu Jing had not seen him personally, he would not believe it. Wouldn't it be a pity if Brother Wanrong's such a talent be buried in the mountains and forests? Why didn't Brother Wanrong serve the court?"

To serve the court? Chen Wanrong never thought about it. These days he was just thinking about how to make money. When he heard what he said, he couldn't help but feel a little ridiculous and said, "Wu Xianyan is so heavy. I don't read Confucius and Mencius, and I haven't learned the ways of sages. I am satisfied with being able to live a peaceful life. I dare not have such extravagant hope."

Not only did Chen Wanrong and Huang Boming and Wu Jing call each other brothers, they also had to praise them so much. In Chen Laoshi's mind, it was a matter of glorifying his ancestors, and his face was red: "Mr. Wu is so serious, Wanrong can't afford to be a good person. Wanrong only knows how to do chemical engineering, but he can't be an official. Wanrong has one thing in chemical engineering, very good!" Although he was humble, he looked content with a look of complacent, and he was clearly boasting.

Chen Wanrong has done so many unexpected things, but none of them have ever been praised by a great scholar like Wu Jing. You should know that people like Wu Jing are rarely praised. He praised Hua Gun with a word. Even Chen Wangshi, who has always been modest, praised Chen Laoshi from the bottom of his heart, and nodded with joy.

Wu Jing's eyes flashed with a divine light and asked curiously: "Brother Wanrong, what is chemical engineering?" If he said alchemy, he would definitely laugh it off and not take it seriously, but chemical engineering is a new thing, so he couldn't help but be curious.

Although chemical engineering has developed from alchemy, it is essentially different from alchemy. The greatest achievement of alchemy is to deceive people, and chemical engineering benefits the people.

Wu and Huang visited Chen Wanrong to understand the problem, and their purpose was achieved. They originally planned to go home. When they heard that Chen Wanrong had another skill, they couldn't help but feel curious and determined to get a glimpse of the truth. Huang Boming was also curious, but he was not as steady as Wu Jing, and said anxiously: "Brother Wanrong, can we see it?"

Now Huang Boming admires Chen Wanrong so much that he is full of regret. He does not see the whole picture of chemical engineering and will regret it for the rest of his life.

If you want to explain chemical engineering to a great scholar like Wu Jing, you must not explain it like Chen Laoshi and others. It can be done in just a few words, which cannot satisfy his desire for knowledge. If you explain in detail, it is not impossible. It involves too much and can write a monograph, which takes too much time. Chen Wanrong is really embarrassed.

After a brief measurement, Chen Wanrong had an idea and said, "Please invite Mr. Wu and Mr. Huang to move. I will show you a chemical product and you will know what chemicals are."

When the two heard this, they hurriedly said, "It's a blessing for Brother Wanrong." They followed Chen Wanrong and came to the main hall.

The table in the main room was filled with soap, and the rosin smell was floating all over the room. Chen Wanrong picked up a piece of soap and explained: "Please look, this is soap. Do you know what you are made of?" It's not that Chen Wanrong likes to keep it in a silence, but asked a small question to make them more impressed.

Each of them picked up a piece of soap and put it on the nose to smell it. Huang Boming browed and said, "The rosin smells like, add rosin."

As long as there is no problem with your nose, it is not surprising at all. Wu Jing gently touched the soap with his right index finger, rubbed it on the belly of his thumb, and commented: "It is very smooth and delicate, and it is very comfortable to rub."

He is much better than Huang Boming. Huang Boming only noticed the smell, but he could evaluate a performance. Chen Wanrong praised his observation in his heart. Wu Jing continued: "I really can't guess it, so please give me a message from Brother Wanrong."

"This is made of lard." Chen Wanrong gave the answer.

Huang Boming burst out laughing and shook his head and said, "Brother Wanrong, I didn't find you still able to joke. It's funny to joke. Lard is so greasy and the soap doesn't feel greasy at all. How could it be made of lard?"

Chen Wangshi and his wife trusted Chen Wanrong so much, and they didn't believe it when they came to this matter, so they refined half of the lard. After hearing his questioning, Chen Wanrong was not surprised.

In the eyes of the ancients, using lard to make soap is not a strange thing, it is a big strange thing, and it is hard to believe it. Although Wu Jing has learned a lot, he is not immune to the vulgarity. He is a little unbelievable and asked, "Brother Wanrong, is this true?"

Chen Houshi could no longer help but defended Chen Wanrong: "Oh, Mr. Wu, what did Wanrong lie to you? This is indeed made of lard. Look, Wanrong is greasy, isn't it just made of soap?"

It was obvious that Chen Houshi did not tell lies. Huang Boming was incredible and said in surprise: "It's too hard to believe. Lard can actually make this thing!"

"Larber and soap seem to have nothing to do with each other, but they have a close connection in the face of chemistry. It is precisely because of this connection that I made lard soap." Chen Wanrong pointed to the soap and explained the chemical industry. He just said that chemical reactions were the connection between substances. This is true. If the chemical reaction had not linked two different substances together, chemical products would not have been made.

Wu Jing sighed: "The world is so wonderful and complicated. If you don't see it, you will be shocked. If you didn't see it with your own eyes, no one would have believed that lard can be used as soap. Brother Wanrong, what are the uses of soap? Brother Wanrong spared no effort to do it?"

The purpose of making soap is to make money. This is because of the poor family. Chen Wanrong said a little self-deprecatingly: "Mr. Wu, I feel a little embarrassed to say it. I make this soap just to sell some money and support my family. Soap has a good stain removal ability and is much better than acacia powder, especially suitable for washing silk and other fabrics."

"It's better than soapberry powder? Is there such a thing?" Huang Boming looked disbelief.

From the appearance of soapberry powder to the Tang Dynasty, our ancestors have used it for many years. There will be no problem in two or three thousand years. No one dares to say that there is a better detergent than soapberry powder. Although Chen Wanrong's words are a big deal, in the minds of Wu and Huang, it is a big talk. Huang Boming would rather believe that the sky can poke a big hole than soapberry powder.

Although Wu Jing didn't say it, he didn't believe it.

The two of them didn't believe it, Chen Zhongshi was very dissatisfied and had to argue with him as soon as he opened his mouth, but he stopped him. It was not surprising that they knew that they had this kind of expression. Chen Wanrong was determined to have a fact better than eloquence and said, "If you don't believe it, let's try it now."

"Brother, how do you try?" Chen Zairong put down the soap in his hand, rubbed his hands, and waited for Chen Wanrong to give his order.

Chen Wanrong calmly said, "Just take a piece of clothing to wash."

As soon as he finished speaking, Chen Laoshi turned around and ran away. The words "I'll go get water" ran far away before they came. Chen Zairong didn't say anything, took off his shirt and said, "This one is just dirty, so wash it."

"Zairong, if you have dirty clothes at home, you should wear them quickly." Chen Wang asked Chen Zairong.

Chen Zairong said without thinking: "Mom, just it!"

Brothers are brothers, and Chen Zairong doesn't believe that soap can wash clothes. He still stands on his side and takes off his clothes without hesitation to test. This is his unreserved support for himself. Chen Wanrong is particularly moved.

Chen Laoshi had already come with clear water, and Chen Wang did not say anything. Chen Wanrong picked up Chen Zairong's clothes and spread the collar. He saw a lot of sweat stains on it and said, "Please look at it, two." Soak the collar in water, then apply a little bit of soap on the collar, rub it a few times, and then wash it with clean water. Without even looking at it, he unfolded in front of the two: "Please look at it, two."

Although it was an experiment, it was too rude to wash clothes in front of the guests. Huang Boming kept complaining about Chen Wanrong's rudeness, but he had to bear it just to get a glimpse of what happened. He glanced at the collar and his eyes widened involuntarily, staring at the collar with a look of surprise: "Brother Wu, it's really better than soapberry powder. Brother Wu, take out your pancreas and try it out to see which one is better?"

When Chen Wanrong heard Li Qingquan talk about it, he had long wanted to see the masterpiece of our ancestors' supreme wisdom. When he heard this, he became curious and couldn't wait to say, "Mr. Wu, can you show me the genus?"
