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

Liu Tan deeply felt that Liu Ju was less worldly than Liu Che, and in order to retaliate against him for throwing the matter to himself, Liu Tan even secretly asked Liu Che to give Liu Ju some homework during dinner—let him do more research. crop.

How can you be a good emperor if you don't even understand the foundation of the people's life, or even the foundation of the Han Dynasty?

Liu Che thought about it for a while, and it seems that the education of the prince is indeed lacking in this aspect. Yes, Liu Che will take Liu Shi to the annual Xiannong ceremony. After that, the emperor and the prince will not go - no one dares to let the emperor and the prince really go to the ground.

There are all kinds of snakes, rats, insects and ants in the field, who can afford what in case?

Therefore, Liu Ju is very sensitive to the tax data of the big man, and knows some grain production and the like, but basically knows nothing about the crops.

I don't even know the original appearance of some ingredients.

Liu Che directly listened to Liu Tan's suggestion and planned to have someone plant some crops for Liu Ju in the palace next year, so that Liu Ju could observe carefully.

Seeing that Liu Zheng, who was almost thirty, never expected that he could get homework assigned by his father at this age, he glanced at Liu Tan in a daze, and immediately turned evil when he saw the little bastard smiling so hard that his teeth could not see his eyes With courage, he said softly: "I really don't know much, not as good as my younger brother, but that's why I want my younger brother to study it. When the grapes were transplanted, there were so many people in the court and none of them could be a father. Huang Fen was the one who solved the problem, and in the end it was brother who took the initiative to understand the matter."

Liu Che thought so too, and his son is a little fairy. Although he has never heard of any ability to turn stones into gold, he seems to have some skills in tossing crops, so he waved his hand: "Okay, I will leave this matter to you." Let's talk."

After speaking, he worried that his son was under too much pressure. In fact, in Liu Che's view, it's okay even if he can't grow it. He can buy it if he wants to eat it. Anyway, he is not short of money.

So Liu Che warned again: "If you can plant it, plant it, if you can't plant it, forget it."

Liu Tan: ...

The two brothers who hurt each other looked at each other, and they were all stupefied.

In fact, this wave is relatively easy for Liu Tan. After all, Liu Che has already said that it doesn't matter if he grows or not.

After Liu Tan went back, he added an item to his schedule. After he finished it, he looked at it and felt that the research on food crops might have to be put in the back row, even after he returned to the northern border country. Besides.

If this is tossing in Chang'an, how can he go back if next spring is the critical moment?

If he could not go back at that time, he might have to wait for the results to come out, then he might really not be able to go back.

On the second day, Liu Tan took the people Liu Che sent to him and wandered out of the palace. First, he went back to the palace.

When he passed by, it seemed that Lu Xuan had just finished his breakfast and was dealing with some important documents.

After hearing that Liu Tan was coming, he immediately put the documents aside and greeted him.

When Liu Tan saw him stand up, he said, "What are you doing up? Careful about the wound!"

Lu Xuan held his hand and said with a smile: "Your Majesty sent someone to deliver a good plaster, and after using it, it's already much better."

Liu Tan took him by the hand and went back to the dormitory and asked, "Father sent someone here?"

Lu Xuan said: "Yes, not long after I arrived at the palace, His Majesty sent someone to ask."

Liu talked for a while, and couldn't help but twitch the corner of his mouth, feeling as if he had been tricked again.

After he returned to the palace, he first went to the dining room to make a dish, and then turned around to go to the announcement room. At that time, the people sent by Liu Che must have gone back, so Liu Che knew the extent of Lu Xuan's injury at all, and he still pretended Ask him about Lu Xuan's injury.

Liu Tan thought for a while if he had exaggerated Lu Xuan's injury for other reasons, then he might really be receiving the education of love from his old father.

After sitting down, he asked, "Have you eaten the food I sent yesterday?"

Lu Xuan looked at him and smiled, "Delicious!"

Liu Tan immediately became vigilant: "I specifically told you not to eat too much yesterday. You didn't eat too much, did you?"

Although I don't know if ducks have any bad effects on the wound, it is indeed not suitable to eat too greasy during the recovery period.

Lu Xuan looked at Liu Tan pitifully: "I didn't eat a lot."

Seeing how pitiful he was, Liu Tan couldn't help laughing and said, "When you recover from your injury, you can eat whatever you want."

While talking, he pinched Lu Xuan's face, and in an instant his hatred for Xiaoli Lake was aroused - Lu Xuan's skinny cheeks were going to sag!

This time he really suffered a lot, and it was all because of Xiaoli Lake!

If it wasn't for the fact that Lu Xuan led troops to fight over, Lu Xuan wouldn't be injured, and if Lu Xuan wasn't injured, he wouldn't hide it from him. Two are now in one palace and one outside the palace.

All in all, very angry!

However, Liu Tan had already made several accounts of Xiaoli Lake in his heart. Anyway, he would have to settle the accounts sooner or later when he went back, so it was not bad.

Lu Xuan held his hand and kissed his palm, and even bit Liu Tan's fingertips lightly.

For a moment, Liu Tan threw everything aside, and couldn't help but feel hot on his face—he and Lu Xuan haven't seen each other for a long time, maybe they haven't been intimate for a long time, and the two are both young and full of blood. kind of reaction.

That day in the carriage Liu Tan directly pushed Lu Xuan down, but today he hesitated for a moment.

Lu Xuan, a person who has no chance, has to create opportunities, let alone now.

If Liu Tan didn't remember that he was injured, he might not even think about going to Shi Heyuan today.

When he pulled Lu Xuan off his body with all his strength, his clothes were all messed up.

Lu Xuan hugged his waist and said with great reluctance: "How long are you staying there? Otherwise, I'll go with you."

Liu Tan was a little hesitant. He probably wouldn't come back this time if he couldn't figure it out. Then the problem came, and he didn't know how long it would take to get it done.

Seeing that his attitude was wavering, Lu Xuan stepped up and said: "You see, it doesn't make any sense for me to stay in the city alone."

If he didn't say this, Liu Tan might still agree, but when he said this, Liu Tan felt that he was really letting him go, and he was afraid that "the king will not go to court early".

Liu Tan said decisively: "You have to come to Beijing one after another in the next few days. Da Honglu also has a new candidate. The prince may meet him in advance."

Lu Xuan brazenly hugged Liu Tan's waist, buried his face in his chest and said, "I'm not an envoy from a foreign country!"

Liu Tan stroked his dog's head: "Then you have to go too."

What a great sign, it's time to show it, neither Liu Che nor Liu Ju will miss this opportunity.

Lu Xuan: ...

Regardless of his injury, he ran day and night just to get along with Liu for a while, but his wife was busy with other things and didn't take him with her!

Liu Tan leaned over and kissed the corner of his mouth: "Okay, it will be fine after the Chinese New Year, and then we will go together."

Lu Xuan asked vigilantly: "Are you going to be busy again when you go back?"

It has been nearly a year since Liu Tan came out, and he will definitely have to deal with the backlog of things when he goes, especially when there are a group of students waiting for him to go back to the palace for the exam!

Liu Tan originally wanted to say that with Huo Guang around, he had nothing to deal with, but after thinking about it, it seemed that... there were indeed many things, so he simply said: "I have nothing to do between the end of the new year and the fifteenth day of the first lunar month."

Lu Xuan calculated and said sadly: "There is still more than a month."

Liu Tan once again acted as a scumbag, turned his head and left ruthlessly.

Miao Rui and Bi Gao who were waiting at the door were obviously a little surprised - they had already made preparations for their Royal Highness to stay overnight in the palace tonight.

Liu Tan looked at their expressions and thought: Why stay here? Isn’t it torture if you can see but can’t eat?If the two of them failed to control it, and Lu Xuan's wound worsened again, where would he save his face if word spread?

But even so, Lu Xuan has been sticking to Liu Tan from the dormitory to the palace square.

After getting into the carriage, Liu Tan was relieved. He was really worried that Lu Xuan would carry him back any minute.

It's just that after returning to Shi Heyuan, he discovered a very important thing - what was the previous difficult problem when he left, and what is still the same now.

In the past few days, he was busy making Kongming lanterns, busy with Nanwu, busy with picking up Lu Xuan, busy getting his father something new to try, how could he be in the mood to think about other things?

As a result, he forgot the most important thing, so the current situation is that even if he returns to Shi Heyuan, he can't proceed to the next step immediately - if the thermal energy of the hot air balloon cannot be further increased, the hot air balloon will still be unable to fly too high.

Liu Tan pinched his brows with a headache and began to think about how to make the hot air balloon go up smoothly.

Blowers... It's not that they don't exist these days, but now people don't call them blowers, they call them bellows.

Liu Tan said that this kind of bellows is very common in those metal smelting workshops. If it weren't for the appearance of bellows, it would be impossible to smelt good-quality ironware before coal was found.

The effect of the bellows is indeed good, but it is not suitable to be placed on a hot air balloon. Now that the hot air balloon has just started, it is hard to say whether it can carry people, even if it can carry people, it is limited.

How is it possible to add another bellows?

And even adding a bellows is not enough, someone has to operate it, which increases the weight of the bellows and a wrestler, and the pressure of the hot air balloon is too great.

The most important thing is that Liu Che stood in front and enjoyed the scenery. If he was happy, he might be very poetic, but at this time, there was a person behind him who was still pulling the bellows.

Why, do you still have an accompaniment?

Do not look at the beauty of the painting!

Liu Tan thought about it for a while, and the easiest thing to do now is to place a fan under the flame, and the wind generated by the high-speed rotation of the fan will blow the flame more vigorously.

Then the problem comes, it is easy to add a fan, but it is not easy to make the fan rotate.

In the age without electricity, what he can use is either the force of nature or manpower.

Manpower must be ruled out first, he just doesn't want too many people in the basket of the hot air balloon.

Then it can only rely on natural resources, and in mid-air, the only power that can be used seems to be wind power.

When Liu talked about it, he laughed directly, using wind power to transform it into wind power. Why does this sound so much like a nesting doll?
