"Okay, you don't have to look at me with that look. I'm just an idea. By the way, I have forgotten about the Tiangong Department recently. What's the steam car you mentioned? After I finished watching it last time, why hasn't it been since I watched it?" Li Er suddenly remembered that there was still this kind of thing.

"Hey, your husband, you have forgotten that the steam car should be transformed now. If you want to get one, you can directly ask the Tiangong Ministry to build one for you. The Tiangong Ministry is busy improving the steam train now." Zhang Nan said with a smile.

"Steam train? What is that?" Li Er asked strangely.

Zhang Nan then briefly explained to Li Er what trains are and what changes the appearance of trains can bring to the Tang Dynasty.

"What you mean is that you need to build a railway track between the major prefectures and prefectures of the Tang Dynasty that can drive this steam train, and then it will be easier to exchange materials in major prefectures?" Li Er asked with a strange look. Although Zhang Nan's idea sounds pretty good, why does it sound so unrealistic?

The land area of ​​the Tang Dynasty is not small. Even if it is just built in a few prefectures, it sounds quite unrealistic. It will cost a lot of iron. Of course, this is just Li Er's idea.

"It is not only the exchange of materials that will become simple, but more importantly, the circulation of commercial and information, as well as the circulation of the people." Zhang Nan explained.

As the saying goes, if you want to be rich, you must first build roads and build railways. This sentence is not in vain. The role of railways in the development of a country is self-evident.

"I understand the truth, but even if you lay some tracks made of iron in the major prefectures of the Tang Dynasty, the iron will rust. How simple is it to be as simple as a few miles between the major prefectures? If there is a problem with a distance, what do you do?" Li Er asked.

"This problem is easy to solve. We set up small stations between the major prefectures and prefectures in the Tang Dynasty, where special railway maintenance personnel are placed. The daily work is to inspect the complete situation of the railway, so that the risks can be minimized." Zhang Nan said.

"Well, this matter is not a small matter. Once construction starts, it will be a matter of the entire Tang Dynasty. This is a national policy. I cannot agree to you so easily. I have to see the steam train before I can make plans. If the steam train is really as useful as you said, I will consider it again. After all, this is not a simple job that can be done with iron." Li Erdao.

Zhang Nan nodded too. In fact, the steam train is still in the renovation stage, so Zhang Nan is not in a hurry.

"There is another thing. When will the crops you mentioned can be made for me? I remember you said that you need a suitable ship. Now you have even made a car that can run without horses. Should you also care about this boat that does not require oars?" Li Er asked suddenly.

When Zhang Nan heard Li Er's question, he realized that there was still such a thing. Li Er would have forgotten even if he didn't say it.

In fact, Zhang Nan cannot be blamed for this. The main reason is that there has been no famine in the Tang Dynasty recently, so there is enough food. I can't remember the fact that there is still food.

"Your Majesty, do you still remember it? I forgot it." Zhang Nan scratched his head and said, "This matter is a historical issue for Zhang Nan, and Zhang Nan did not expect Li Er to remember it."

"Nonsense, how could I forget this kind of thing? If I really brought back those crops that were two or three ripe in a season, our people in the Tang Dynasty would never go hungry again. Can you forget such important things?" Li Erdao.

"Okay, you are the leader of the Tiangong Ministry. As long as I have the result, I can postpone it by steam trains. Do you understand the matter of this ship, if you want to turn it into the top priority of the Tiangong Ministry?" Li Er directly issued an order without waiting for Zhang Nan to answer.

Zhang Nan had no choice but to agree. He didn't do anything, but Zhang Nan still trusted the craftsmen of Tiangong Department very much.

After playing snooker with Li Er for a few more games, Zhang Nan estimated that the time was almost over, so he said to Li Er: "Master, the time should be over. Let's go back and continue to get the hair for the Empress. After getting the hairstyle ready, let Yue'er put on makeup, which is definitely no different from what you saw in the morning."

When Li Er heard this, he put down the club in his hand. Anyway, he would lose in this game, so Li Er didn't want to continue playing. However, when Li Er returned to the accommodation, he didn't enter the room as soon as possible. Instead, he had a stomachache and had to go to the toilet.

Although there is a private bathroom in Li Er's private room, Li Er always feels that it is strange to go to the toilet where he sleeps, so Li Er still goes to the toilet outside, while Liu Bing accompanied Comrade Li Er to the toilet, and Zhang Nan went back to the room in advance.

When they returned to the room, Zhang Nan discovered that Yang Fei and Cui Yue had already returned to the room.

"Langjun, you are back. You have been waiting for you for a long time." Cui Yue quickly stood up and said, seeing Zhang Nan coming back.

Zhang Nan smiled and scraped Cui Yue's nose and said, "What's the hurry? Am I back now?"

The simple interaction between Zhang Nan and Cui Yue made Yang Fei see clearly. Yang Fei smiled and said, "You little couple have a good relationship." When Zhang Nan heard this, she hugged Cui Yue's waist openly and said, "Of course."

When Concubine Yang saw Cui Yue's happy and happy look, she said enviously: "It's so good. I heard that even the emperor wanted to betroth Princess Changle to you, you refused?"

"Hey, I think it's enough for me to have Yue'er, and I don't need anyone else." Zhang Nan said with a smile.

"It's so good." After Yang Fei said that, she stopped talking. Zhang Nan could see that Yang Fei was also very envious of being able to be favored by someone, but Comrade Li Er definitely couldn't do it, let alone Yang Fei was not favored.

When Zhang Nan saw Yang Fei's sad look, he quickly changed the topic and said, "Empress, I will get your hair ready for you now. It's almost time. All the potions should have been absorbed by the hair."

"Did you say you just dripped the potion on my head? Why is this medicine not bad at all? Instead, it has a strong fragrance?" Yang Fei asked strangely.

While removing the clips on Yang Fei's head, Zhang Nan explained to Yang Fei what was going on. After all the clips were removed, Zhang Nan asked Cui Yue to take Yang Fei to wash her hair again.

After everything was ready, Zhang Nan took out the cosmetics that had been prepared long ago and started asking Cui Yue to paint Yang Fei. Why didn't Yang Fei draw it herself? It was because Zhang Nan really did not agree with the aesthetics of the Tang Dynasty. Even if Zhang Nan brought later cosmetics to the Tang Dynasty, the aesthetics still remained unchanged.
