It's better to be Yiren. Chen Wanrong was so moved that he hugged Zheng Qing tightly: "Being able to be married to you is the greatest happiness in my life!"

Zheng Qing knew that Chen Wanrong was the truth, and was both happy and unable to afford it. She whispered: "A man has ambitions in all directions, and you should spread your wings and fly high above the sky!"

Chen Wanrong enjoyed a lot of encouragement words and smiled and said, "I don't know when I will meet again when I will meet. Tonight, you have to compensate me."

Zheng Qing's face turned red, she gave Chen Wanrong a blank look, and nodded gently again. She lowered her head in shame and rubbed the corners of her clothes. Chen Wanrong couldn't bear to tease her anymore, so she picked up Yiren and put it on the bed.

The next day, Chen Wanrong slept until midnight before getting up. With Zheng Qing's help, he dressed neatly, used food, and rushed to the military weapon prison. Because there was still a lot of things to do today and he couldn't accompany Yiren.

As soon as Chen Wanrong arrived at the Military Weapon Prison, he immediately found that the Military Weapon Prison was very different from the past. He couldn't help but be surprised. He stared at Ye Tianheng and asked, "Master Ye, what's wrong with your eyes? It's as red as a rabbit's eyes!"

Not only Ye Tianheng's eyes were red, but Kou Yibing, Liang Lingzan, Monk and his party were all red. Chen Wanrong saw it and was shocked in his heart and asked, "Whose treasure are you jealous of?"

Everyone laughed loudly, but no one answered his question. Ye Tianheng took Chen Wanrong's hand and sat down, saying, "My friend, look, is the steam locomotive like this?" As he said that, he pushed the drawings in front of Chen Wanrong.

Chen Wanrong picked up one picture and looked at it. It was an appearance diagram, an organic nose, and a carriage. Judging from the appearance, it was almost the same as a modern motorcycle. As soon as he said yesterday, they took out the drawings today. Chen Wanrong was surprised that this efficiency was too high.

Chen Wanrong sighed that it was difficult for them to design like this.

I picked up another one and it was a railway track diagram, with rails and sleepers, which was not much different from modern railways.

Chen Wanrong became more and more surprised as he looked at it. Another one was the structural diagram of the motorcycle. Chen Wanrong could understand it, but he didn't know if it was right. After all, Chen Wanrong was not a motorcycle engineer, so he knew nothing about it.

Suddenly, Chen Wanrong understood: "Master Ye, you guys got together to draw this drawing last night? No wonder your eyes are so red!"

Ye Tianheng smiled and said, "My friend, you are about to go to the Western Regions. We have to do things as well as possible while you are here. After you leave, if there is any problem, who will we ask?"

Chen Wanrong was very moved and blurted out: "Then why don't you call me?"

Ye Tianheng smiled, slapped Chen Wanrong's shoulders, blinked his eyes, a little naughty and didn't say anything. He meant that Chen Wanrong's time was limited, so he should spend more time with his wife. Everyone is a man, and there is nothing that cannot be said.

Chen Wanrong was moved by this friendship and smiled and said, "Master, there is no problem with this appearance. To be honest, I don't know much about these structures. Whether it can be used or not depends on you to study them."

Science is practical, and you must pretend to understand. Ye Tianheng and others believe that what Chen Wanrong said is true, but they are very disappointed. They sighed and then said: "My friend, please rest assured, we must study it! Even if we cannot create it in our lifetime, we must pass it on and let future generations do it!"

This sentence is deeply rooted in Chen Wanrong's meaning. Chen Wanrong is very clear. It is impossible to create it in a short time, and there is no hope. The most important thing is to start doing it.

Chen Wanrong agreed with this and said, "What the master said is good, so it should be. However, there are a few new things that I will tell you today and we must start doing them."

The monk and his party suddenly became energetic and hurriedly said, "Speak quickly, let's listen."

Chen Wanrong nodded and said, "Even if there is a steam locomotive, the transportation in Datang cannot be more developed, because the locomotives are too large and the cost of laying railways is too high. If it is laid in a place with a small population, it is not cost-effective. This requires another thing to be complemented by it, and this tool is called a car."

"Car?" Everyone heard of this term for the first time, and Dajue was fresh.

Chen Wanrong explained: "The power of a car is not a steamed car, but an internal combustion engine." Next, we will explain it in accordance with the principles learned in physics class.

To be honest, Chen Wanrong's understanding of internal combustion engines is limited to the knowledge of physics teaching. It is impossible to explain it in more detail. Even so, this principle alone is not something that the Tang people could imagine. Ye Tianheng and his friends heard it and stared at Chen Wanrong, and they could not even turn it.

When Chen Wanrong finished speaking, everyone looked surprised and sighed: "There are such magical things in the world, I have seen them!"

Chen Wanrong encouraged them: "As for how to achieve it, I don't know, it requires everyone to work together!"

"No problem!" A firm and powerful voice sounded.

Chen Wanrong was very satisfied with their answer: "Although the internal combustion engine is good, it requires fuel. The fuel of the internal combustion engine is diesel. Where can I get diesel? I get it from the hot turbulent oil."

"Hard turmeric? Can that work?" Everyone's eyes almost fell off.

Yan'an was an oil production site in ancient China. It has been used in military affairs since the Warring States Period and was also used in the Tang Dynasty. The military weapon supervision produced no 100,000 kilograms of hot tincture oil every year. It is really familiar to Ye Tianheng and others.

If you want to use fierce tinder oil on the battlefield, Ye Tianheng and the others believe that if you want to extract diesel from fierce tinder oil, they really don’t believe it!

Chen Wanrong said in an unquestionable tone: "That's right! It's obtained from hot turmeric oil. This requires refining technology! I'll tell you what you know now."

Oil is a modern energy source, and it is willing to start a war for oil, and it has a wide range of relationships. Similarly, although oil refining is related to chemical engineering, it is an independent discipline. Despite this, it is still very related to Chen Wanrong's chemical engineering major, and Chen Wanrong also knows a lot. This lecture is much more detailed than explaining internal combustion engines and steam locomotives.

After Chen Wanrong finished speaking, his throat and hair were dry, he picked up the teacup and poured it into pieces. He poured five large cups in one breath before he could feel comfortable.

Among the people here, Sima Chengzhen has the highest achievements in chemical engineering and the deepest understanding. His eyes are bright and energetic and sighed: "If I had known that useful things could be extracted in this way, it would not have been so hard to refine alchemy!"

Alchemy and oil refining are unrelated to each other. However, the ancient Chinese alchemy technique was particularly difficult to refine because of the backward equipment. He was inspired by his feelings.

Everyone burst into laughter, and Chen Wanrong joked: "Master, don't you want to refine elixirs again, are you?"

"What's wrong?" Sima Chengzhen said with a smile: "Learn Wanrong Chemical Technology, I have become a fairy! "

Everyone laughed loudly, and they were extremely happy.

After the fuss, Chen Wanrong said: "I have finished talking about the most important things. As long as you work hard, all of them will be realized one day. Even if we cannot achieve them, we will do our future!"

"That's! That's!" Everyone stopped nodding.

Chen Wanrong said: "I should go and see your progress, too."

"I will lead the way!" Ye Tianheng grabbed Chen Wanrong's hand, regardless of whether Chen Wanrong agreed or not, and walked in his head with a crutch. Sima Chengzhen and the others hurriedly followed.

Chen Wanrong asked, "Master Liu, how are you choosing?"

Liu Huaide smiled and said, "It's generally okay."

Chen Wanrong heard it and asked, "What about the small problem?"

Liu Huaide was stunned for a moment before saying, "General Chen, there are two people, and I have to ask you to deal with it."

"Oh! Which two?" Chen Wanrong was very interested and couldn't help but stop.

Liu Huaide said a little embarrassedly: "One is Zheng Wanru, who is determined to go to the Western Regions. However, the Western Regions are too hard, so I don't want him to go."

Chen Wanrong pointed at him and said, "You think he is my brother-in-law and want to take care of him, right?"

Liu Huaide blushed and said, "That's what it means!"

Chen Wanrong patted his shoulder and said, "Respect his meaning. If he wants to go, let him go. If a man is afraid of suffering, he can still call him a man? Although it is hard to go to the Western Regions, it is far from the soldiers fighting on the battlefield."

Liu Huaide hurriedly said, "General Chen, please rest assured. I will arrange for him to go. Gao Jian wants to go to the Western Regions, but the Taoist priest will not let him go." Looking at Sima Chengzhen.

Sima Chengzhen hurriedly explained: "My friend, you know that Gao Jian has a good understanding. It would be a pity if he went to the Western Regions. After all, the Western Regions are about using ready-made technology to keep him in Chang'an and he can study new technologies."

Chen Wanrong nodded and said, "The Taoist priest is right! It is good to go to the Western Regions to help the army build weapons, and it is to contribute to the Tang Dynasty. However, the most advanced technology should be placed in Chang'an, and the best talents must be placed in Chang'an for research. Gao Jian has a good understanding, so he doesn't have to go."

Liu Huaide was still a little embarrassed: "General Chen, as soon as the news of his trip to the Western Regions came out, the military weapon prison was in an instant and rushed to go. Gao Jian was the most active person, how could I tell him?"

Chen Wanrong was very good at giving up: "Master Liu, you don't have to worry about this." He whispered Sima Chengzhen.

Liu Huaide understood and smiled and said, "Yes, this matter still has to fall on the Taoist priest."

"Okay! Let's talk!" Sima Chengzhen appreciated Gao Jian very much and accepted the order happily.

Chen Wanrong reminded him: "Master Taoist, you can tell him that the court will reward him with great rewards after researching the results."

"Vulgar, vulgar! Immortal Heavenly Lord!" Sima Chengzhen's calm man was not interested in rewards. He came to study chemical engineering wholeheartedly, and was interested. When he heard this, he couldn't help but make a noise.

Chen Wanrong and the others laughed. As they were talking, they came to the place where sulfuric acid was produced. Chen Wanrong looked around surrounded by everyone. I have to admit that they did better than Chen Wanrong imagined, and Chen Wanrong was very satisfied.

After watching the production of sulfuric acid, I looked at the production of copper sulfate, and finally saw the effect of Bordeaux liquid. When I came to the field, Ye Tianheng was very excited and pointed to the left and said, "My friend, look, this has never been used. Look at the leaves, they were not gnawed by insects, one was missing. Look at them, they were sprayed with medicine, but they were different. They grew very well, green and there was no lack of leaves."

Chen Wanrong took a closer look and he was right. Compared with the Bordeaux liquid sprayed and the one that had not been sprayed, the gap came out. It was very obvious and could be seen at a glance.

As he was talking, a few people came over, and Li Longji was walking in his head. Li Longji saw Li Longji fluttering sleeves, his steps were light, and he walked quickly. Chen Wanrong and the others hurriedly came up to greet him. Li Longji waved his hand and said, "Forgive! Forgive!"

"Chen Wanrong, you did a good thing!" Li Longji pointed at the crops happily and said, "Look, those who have sprayed medicine are completely different from those who have not sprayed. Food is the most important thing for the people. If the crops are well planted, this is the top priority. Just this, it is not unfair to meet your requirements!"

China is a very successful agricultural power. All dynasties attach great importance to agriculture, so Li Longji, the wise ruler, naturally attaches great importance to it.

"The emperor is so serious, it's all the credit of everyone!" Chen Wanrong said humbly.

Li Longji's eyes were idle and said naughtyly: "I didn't say the credit, it's because you're too careful!"

Everyone laughed loudly. Li Longji pointed to the farm and said, "I want to make more sulfuric acid this year and make more copper sulfate, and spray them in Guanzhong tomorrow. First, solve the grain in Guanzhong, so there is no need to transfer grain from other places to the capital. When the conditions are ripe, then promote it to other places, and it will be used throughout the country!"

This has been said a long time ago, but again, it was still arousing. Ye Tianheng and the others were very happy, and they were so happy!

I used to say that it was just a talk on paper, but now I say that it is because it has been confirmed. Hope is right in front of me, so how can it not make people happy?

Li Longji looked at it for a while, clapped his hands and said, "I am here to see the crops, not to see you, don't be too careful! Let's go!" With the respectful sends from Chen Wanrong and the others, he turned around and left.

Looking at Li Longji's back, Ye Tianheng was as happy as a child: "My friend, I didn't tell you that the emperor has to come and see it every day, no matter whether it is sunny or rainy. Every time the emperor comes, he always leaves happily! Just like today!"

Food is the most important thing for the people. As long as the people have food to eat, the world will be stable. The emperor is also a qualified emperor to do this. Of course, Li Longji is happy!

During these three days, Chen Wanrong was busy, after finishing the military weapon surveillance, he had to go to the Western Regions affairs. He was simply a circle and had no time to spare.

In a blink of an eye, it was the day to set off. On that day, Chen Wanrong got up very early. Zheng Qing brought hot water and arranged for Chen Wanrong to wash up. She was about to part with Yiren. When she went there, she didn't know when she would be back. Chen Wanrong was extremely reluctant to leave and looked at Yiren, speechless.

On the contrary, Zheng Qing comforted him: "You go this time, don't worry about your family. I can take care of your family's affairs!"

Chen Wanrong was stunned and said, "Don't worry, I will take good care of myself!"

The people who went to the battle were not so worried. What they were worried about was the people who stayed at home. Zheng Qing's eyes turned red and tears fell: "You must take care of yourself! They are waiting for you to come back!" She couldn't help but hug Chen Wanrong and sobbed.

To be honest, Chen Wanrong couldn't bear to part. However, this expedition was of great importance and much greater than the previous two expeditions. If this expedition was successful, Chinese civilization would be promoted to the Western world. As long as he was a man, he would do it without hesitation. Chen Wanrong hugged Yiren, kissed Yiren gently on Yiren's cherry lips, and pushed Yiren away and said, "Don't worry, I will definitely come back! Who told me that there is a wife in my family who can't be left with me?"

Zheng Qing was both ashamed and anxious, and she was crying, hugging Chen Wanrong tightly.

Chen Wanrong stroked her hair, hugged Yiren's slender waist, and comforted her softly: "Don't worry, I'll be fine!"

Zheng Qing couldn't stop nodding, but she didn't let go. Since the two met, Zheng Qing has been very strong and masculine. She has not been as good as a sponge baby, and she couldn't help but feel tender. Chen Wanrong was about to say something to comfort her, but Zheng Qing let go of Chen Wanrong and wiped her tears and said, "What you promised, you must come back!"

Chen Wanrong nodded firmly and said, "That's certain! If I don't come back, can I bear to give up on you?"

Zheng Qing smiled sweetly and urged: "It's getting late, let's go!"

Chen Wanrong took Yiren's hand and said, "You have to send me." The two came out together, and saw Zheng Jianqiu and his wife, and Chen Laoshi and his wife had been waiting for a long time.
