I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Liu Tan felt a little tired in his heart: "Father, it will be almost ten months if you delay, what if you can't catch up with Zhengdan?"

Zhengdan is a big festival, usually at this time the foreign envoys have already set off for Chang'an, although those envoys will be received by Honglu even if they arrive in Chang'an, and they will not see the emperor at all, but it is still a different matter if the emperor is not in Chang'an.

Liu Che said calmly: "Shuofang is not far from Chang'an, otherwise why did you worry so much when Wushilu sent troops south? At worst, you will have to march back in time."

Liu Tan asked sincerely, "What are you doing for?"

Liu Che said, "I just want to see what you can make out of sand."

Liu Tan: ...

How should I put it, every time I want to go back and strangle myself talking nonsense.

He choked and said: "But this is not something that can be done in a day or two. Erchen has to deal with the accumulated business affairs in the past two days, and tomorrow I have agreed to accompany you to play on the ice car fishing."

So it must be the day after tomorrow to do it formally. Of course, he does not need to burn the glass himself, but he must ensure that the craftsman can find him at any time if there is a problem, and he can even go to see the situation at any time.

This meant that he had to spare at least a day or two to do this.

Liu Che said very simply: "You go now."

Liu Tan took a deep breath, resisted the urge to scold the emperor, and said in a good voice: "Father, my son really hasn't dealt with things for a long time..."

Liu Che said calmly, "Bring me the documents, and I will handle them for you."

Liu Tan: Damn it!

Huo Guang: =mouth=!

The two of them looked at each other, and Liu Tan held back his shock and said, "This... the emperor came here to relax, how could the emperor take the place of the minister..."

Liu Che ran out of patience: "Stop talking nonsense! How can you still tire me out with your little things?"

The situation Liu Tan is facing now is a bit difficult, but these difficulties are more related to foreign enemies and money.

Now the Huns conservatively estimate that they should be able to be honest for a period of time, and the rest is the problem of money. This will not be resolved for a while and can only be done slowly, so even if they deal with things, most of them are trivial problems.

For Liu Che, it was nothing at all, let alone the current him, even the him back then could handle it smoothly.

We must know that when Liu Che succeeded to the throne as a young man, at that time he faced the old ministers who were in power, the princes and kings who were eyeing him, and the queen mother who tried to control him. As for the relatives, they were all from the queen mother's group.

In this case, he packed up all of them. At that time, he was about the same age as Liu Tan.

Liu Tan choked for a moment, then turned his head and ordered, "Let Zhu Shanzhang come here with the assigned documents."

Then he turned his head and said to Liu Che: "I keep Zhu Shanzhang by my side and ask him to classify the documents first. If the father doesn't use them smoothly, he can change."

Zhu Shanzhen is a novice, Liu Che may not be willing to bring such a novice, it is better to let Liu Che change.

As for whether the state affairs of the northern border country will be remembered, that's up to you. Anyway, Liu Che has seen it, so what if they remember it?Can he still turn black and white in front of his father?

Liu Che nodded, and not long after, Zhu Shanyan came over with a stack of documents. Liu Tan saw that he was a little shaky when he walked, and he probably wasn't so clear-headed, so he couldn't bear to look directly at him.

In fact, it is not to blame Zhu Shanzhang. It was already a dream for him to be able to stay with the King of the North. Now someone told him that he should assist the emperor in handling the state affairs of the Northern Kingdom. As for His Royal Highness, the King of the North...was sent away by the emperor Do something else.

Zhu Shanyan was so dazed that he even forgot his nervousness and excitement. After arriving in the main hall, he saluted silently, unable to utter a word.

Even in his dreams, he never dared to dream of such a scene.

Liu Tan was worried about Zhu Shanyan, so he glanced at Huo Guang. Huo Guang nodded to indicate that he would stay.

Of course they don't doubt Liu Che's level, but Liu Che may not be too familiar with the current situation in the northern border country. In order to prevent His Majesty from treating the northern border country as the center of the Han Dynasty, especially the treasury of the northern border country as the Han treasury, it is necessary for Huo Guang to stay Make - some reminders.

Liu Tan was a little worried but still said: "Then... Erchen will go and look at the sand."

Liu Che waved impatiently and said, "Go quickly."

Liu Tan had no choice but to take people out. Halfway through the walk, he felt a little panicked, so he simply asked someone to call Lu Xuan over.

These days, except for the one-time shopping with Lu Xuan that day, the rest of the time is basically in a state of separation.

The two people are clearly in the same city, but they have come up with a posture of separation between the two places, which is also a headache.

Lu Xuan was obviously happy. When he saw Liu Tan, there was a smile on his brows and eyes. Liu Tan couldn't help laughing seeing him like this.

Lu Xuan came over and asked, "Don't you need to accompany Your Majesty today?"

Liu Tan suddenly felt a little guilty. It seemed inappropriate for his old father to leave his boyfriend aside when he came.

He said: "Well, Father is helping me with official duties."

The smile on Lu Xuan's face paused for a moment, and gradually turned into confusion: "What?"

Liu Tan had no choice but to explain to him the matter of getting off the glass, and said bitterly: "Father probably thinks that letting me deal with state affairs is a waste of time."

Lu Xuan also asked curiously: "Then you are going to make glass now?"

Liu Tan said: "Yes, but I don't need to do it myself, I just need to order it. Who knows my father... Forget it, just treat me as my father and give me a vacation. Let's go and have a look?"

Lu Xuan readily agreed, although the place of this date is a little special, but—thinking of the state that he and Liu talked less and more often, don't be picky.

Liu Tan took him to the workshop in the palace. At this time, there was a large pile of sand in front of the workshop, and the craftsmen had already arrived here to wait for orders.

Lu Xuan took a curious look at this workshop, it was actually quite ordinary, no different from other small workshops, the only difference was probably that it was a bit cleaner.

But if possible, he believed that countless people would be willing to visit this workshop—this place can be regarded as the treasure house of the King of the North, and many things come out of it.

After reading it, he saw Liu Tan directing people to fill the sand, so he couldn't help going over and asking, "What is this for?"

Liu Tanyan said succinctly: "Burn."

Lu Xuan is in the Western Regions. Although Wusun Kingdom does not have the technology to make colored glaze, he also knows that colored glaze is made by burning.

According to Liu Tan's meaning, that glass is not much different from colored glaze, so Lu Xuan couldn't help being a little surprised after hearing this: "Is the glass made of sand?"

Liu Tan hesitated and said, "It's sort of, but it may not be successful."

Lu Xuan then asked: "Why?"

Liu Tan said: "If you want to add something, it shouldn't burn if you don't add something."

Although Liu Tan didn't know if pure sand burning would work, he still decided not to take any risks.

Lu Xuan nodded after hearing this, and walked to the side tactfully.

Liu Tan will definitely involve some recipes in the process of ordering. Although he and Liu Tan are very close, but the little Wusun and the big man, or the little Wusun and the northern border country still need to be divided between you and me for the time being.

Liu Tan didn't notice him leaving, and he was worrying at this moment—although he knew that alkali and quicklime should be added during the burning process, but it was still an old problem, he didn't know how much to add!

Originally, he wanted to ask everyone if they knew how to burn colored glaze, and wanted to learn from the scriptures, but it turned out that there might be no one in the entire northern border country who knew how to burn colored glaze. In the past, when there was no coal, the fuel was firewood. The northern border country lacked this stuff, and the glass was not easy to burn.

[-]—If the quality of the burnt product is not good, it will lose money instead of making money. Naturally, few are willing to do it.

Because of this, colored glaze is extremely precious in the Han Dynasty, much more precious than gold and jade, except for the royal family, to be precise, except for the princes and kings, no one else is qualified to use it.

Liu Tan rubbed his head, thought for a while and said, "Try a little bit."

Anyway, Li Buyan was generous enough, and the sand was given away as if he didn't need money—heaped it up.

Oh, yes, these sands are indeed free for Li Buyan.

After Liu Tan finished giving his instructions, he turned his head to talk to Lu Xuan, but found that Lu Xuan was not by his side, and after looking again, he found that he had already run to the side for a stroll.

After being surprised for a while, Liu Tan understood what Lu Xuan meant, and couldn't help but laugh, but he didn't let it go, he just walked over and said, "Let's go, let's go to the front hall - eat fruit - and wait."

Burning glass also takes time, and just now Liu Tan also asked these craftsmen to do it freely and let them experiment with different ratios, so it may not produce results in a short period of time, and it may not even work at dinner time.

Anyway, his father is doing his job, so why not just live a two-person world with Lu Xuan.

Of course, Lu Xuan would not refuse, and talked with Liu about a palace that was not considered remote, but very deserted.

Lu Xuan walked in to take a look and said, "Here... it should be built for the future prince, right?"

The location is just to the east, which is about the same as the location of the Crown Prince's uterus in Weiyang Palace.

Liu Tan thought he was thinking of other places so he casually said, "Yes, all palaces in the world are similar to this, but it's a pity that no one lives in this house."

Lu Xuan walked to him and sat down and said with a smile: "That's not sure."

Liu Tan frowned slightly. What he meant just now was that he would not get married, so Lu Xuan should not be so worried. As a result, he just turned his head to express his dissatisfaction when he saw Lu Xuan's eyes staring at him maliciously. holding his stomach.

Liu Tan:? ? ? ?

He threw the hand stove in his hand and said angrily, "What are you looking at? Men can't have children!"

Lu Xuan teased him: "That's not sure, you are a god who came down to earth, don't you say that gods can do everything?"

Liu Tan suddenly became angry, turned around and pushed Lu Xuan hard, Lu Xuan didn't bother with him, and lay down on the mat, and then saw Liu Tan turning over and riding on him fiercely and said: "I don't want will give birth, but gods can make mortals live, do you want to try?"

Lu Xuan supported his waist, and when he was about to say something, he saw Miao Rui, who had been pretending that he didn't exist, walked over quickly and coughed twice, "Your Highness, Your Majesty is coming."

Liu Tan was shocked at once, and when he turned around, he saw his father standing under the eaves, staring at him with an unkind expression.
