Wearing a secret agent with many tricks, the cold and proud prince flirts easily

After the meal, Murong Jing finally understood what a happy marriage looked like.

These two people deliberately made him angry today, and they treated him as nothing.

The emperor's brother first asked the emperor's wife where she had been all morning. The emperor's sister-in-law had been to several places. He said that the emperor's wife had worked too hard. He, Murong Jing, really didn't understand what was so hard about going shopping.

Later, he discovered that the prince was shaving fish bones for his wife. The wife was not the kind of arrogant woman. She often put the dishes that the emperor liked to eat into his bowl and told him the main nutrients of the dishes. What it was, what vitamins, what proteins were mentioned were all words he couldn't understand.

After the two had a meal, it was really clear that they truly loved each other and that they were a couple who cherished each other at the top of their hearts.

"Husband, I'm full. I'm going back home first. I won't disturb you two brothers who are on duty." Lin Yunxi looked at the time. The two brothers were almost on duty.

"Xier, don't be in a hurry to go back home, the three of us will go somewhere." Murong Hao put down his bowl and chopsticks and said warmly.

"Where to go?" Lin Yunxi asked curiously.

"Ministry of Industry, my father asked you to quickly discuss the plan for building a new road with the Ministry of Industry. If you need any raw materials, they will arrange it as soon as possible." Murong Hao said seriously.

"Murong Hao, I've only returned to Beijing for the second day, can't I take a break?" Lin Yunxi discovered that the emperor's father-in-law was very good at exploiting labor.

Murong Hao? Is it taboo for the emperor's sister-in-law to call the prince by his royal brother's name in private?

"Just go and talk to the officials from the Ministry of Industry about what materials are needed, and you'll be back soon." Murong Hao said fondly.

Murong Hao saw her expression of reluctance. She had indeed never rested in Jinwei City. He felt sorry for her, but it was a pity that he did not dare to disobey his father's imperial order.

"Is there any salary for that?" Lin Yunxi joked.

"Well, if my father doesn't give you wages, my husband will." Murong Hao really didn't know if her father would pay her wages for this living job.

"Forget it, why don't you just leave the Prince's Mansion and go? Work for free for the sake of the future of the people."

Lin Yunxi convinced herself that her vegetable oil would be transported from Jinwei City to all parts of the country in the future. The road was not easy to travel and the business would not be large.

"Xi'er is so good." Murong Hao knew that she put the overall situation first.

"Brother Emperor, Sister-in-law Emperor, do you really think that I am nothing?" Murong Jing ate all the dog food today and he was speechless. However, from another perspective, Brother Emperor regarded him as one of his own.

"Yeah." The couple said in unison.

"Hey, I need to find my princess quickly, otherwise I won't dare to have dinner with you." Murong Jing was desperate.

"Husband, why did King Xuan go to the Ministry of Industry with us?" Lin Yunxi just heard that the three of them were going together.

"Sister-in-law, I am currently working in the Ministry of Industry, so please take good care of me in the future."

Today, his father left him and the Crown Prince behind, asking them to strongly support the Crown Princess's road construction plan. He was confused when he heard this. He still can't understand why his father asked the two brothers to cooperate with the Crown Princess in building the road. Father, do you think a weak woman knows how to build roads? However, he did not dare to look down upon the idea that the emperor's wife would build a salt farm.

"Okay, we are a family, please take care of us." Lin Yunxi smiled.

The three of them left Xiyue Restaurant and came to the Yamen where the Ministry of Industry was located.

This is Lin Yunxi's first visit to the Ministry of Industry. It turns out that the six ministries of Dongsheng Kingdom each perform their own duties. Their offices are not in the same place, but they are basically built around the palace. The Ministry of Industry is to the north of the palace.

"Your Majesty, Li Yan, has met the Crown Prince, Crown Princess, and Prince Xuan." Li Yan, Minister of the Ministry of Works, had already been waiting at the gate with other officials from the Ministry of Works.

Since Li Yan was trapped in Xihe Prefecture and the prince and princess rescued him, he has only visited the house during the New Year to pay New Year greetings, and has not specifically thanked him for that matter. He was very happy that the two came today, but there were too many people, so he did not dare say what.

"No courtesy." After Murong Hao responded, the group walked inside.

"Today the emperor told the official that the Crown Princess has a new way to build roads. What specific materials are needed? The Crown Princess just said that the official will have people prepare them as soon as possible. The emperor means to build the road from the upper capital to Jinwei City first. Road to facilitate the transportation of salt." Li Yan explained the tasks assigned to him by the emperor today.

He looked at the Crown Princess in front of him with admiration. The Crown Princess was really no ordinary woman. She could actually purify sea salt. That was the dream of many emperors for many years, but she realized it. Now he heard that she could make it cheap and strong. Li Yan is looking forward to the road ahead.

Lin Yunxi didn't expect that Murong Hao would bring her to the Ministry of Industry when she went out today. She didn't prepare anything, but her brain was good and she memorized several raw materials for road construction.

"Master Li, bring me the drawings and pens. I'll draw them for you now." Lin Yunxi said confidently.

Soon, pen and paper were ready.

Lin Yunxi paused for a moment when she saw the slender brush. She was not used to drawing with brushes, so she directly put her hand into her sleeve pocket and used her usual charcoal pen.

Li Yan and Murong Jing were surprised. Did the Crown Princess prepare a pen in her sleeve pocket? And this one is completely different from the brushes they used.

However, it is said that the Crown Princess is not from Shikoku, so it is understandable that there must be many things they do not know.

Lin Yunxi thought for a while and began to write on the large paper.

Her hands have drawn countless drawings. She almost doesn't use a ruler to draw straight lines, and every stroke is a straight line. At this moment, she wants to thank her mother for forcing her to learn to draw when she was a child, otherwise she wouldn't be able to draw now.

Everyone watched her draw, and she drew a cross-section of the road.

Lin Yunxi considered the limitations of ancient technology and also considered that ancient horse-drawn carriages would not be able to pull heavy goods, so she reduced the modern cement road with five layers to three layers.

The bottom layer is the original soil tamped road surface, the second layer is the gravel rammed layer on the side, and the most important and difficult layer is the third layer, which is the concrete pad layer.

After drawing the road profile, she began to solve the problem of no concrete in ancient times, that is, how to make cement?

Then I continued to break down the problem and found that the biggest problem was the proportion of concrete and the problem of grinding the concrete into powder.

The problem of proportion is simple, but the most difficult step is grinding the concrete into powder.

In ancient times, there were stone mills for grinding rice, but the hardness of rice was low, so it was very easy to grind it into powder.

But to grind and finely grind concrete powder, highly wear-resistant metal materials are needed.

"Master Li, look, this is the cross-sectional view of the road to be built. The most difficult thing now is the concrete pad layer. The proportion of this layer of concrete is here. I will try to bring the stone samples to you in the past two days. You can Ask someone to fetch them. These stones need to be calcined at high temperatures and then ground into powder. This grinding machine is the most difficult part. I will go back and study it in the past two days and give you the drawings."

Lin Yunxi told Mr. Li all the thoughts in her mind just now.

"Princess, you are really amazing. You don't even need a ruler to draw pictures. You can also analyze what needs to be done step by step. I admire you."

Mr. Li was in awe of her when he saw her thinking and drawing at her desk. She was able to come up with such a detailed plan in only half an hour.

"Master Li, thank you. Just wait for me to bring the samples. It is best to build a hot furnace somewhere, like a high-temperature furnace for forging iron. We will try it a few times first. After success, we can start building roads. Come on." Lin Yunxi ordered seriously.

"Yes, I will ask someone to prepare it quickly. Once the ingredients for the Crown Princess are in place, we will start calcining immediately."

Mr. Li agreed, and Murong Hao and Murong Jing standing nearby cast admiring glances at Lin Yunxi.
