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

The corner of Liu Tan's mouth twitched after hearing this, and for a moment he really didn't know how to answer this question.

Indeed, the design of a dam requires corresponding knowledge of water conservancy, or in other words, the ability to master the knowledge of water conservancy to the top.

But Liu Tan doesn't need to know that much at all, just take out all those things from later generations, and use whichever one is suitable.

He had no choice but to start talking nonsense in front of Liu Che again: "The dam is just my son's idea for a while, whether it is actually suitable or not, and whether it can be used here is all for Xu Lin to study, and this dam It's a bit different from Erchen's original design, so... Erchen just came up with an idea."

Well, this is true. He didn’t lie to Liu Che. Although they are all gravity dams, the one built by Xu Lin’s supervision is different from the one he drew. It is achieved by means, so it needs to be deleted, then those things will appear particularly abrupt on the drawings, and the actual construction must no longer be based on the drawings.

Liu Che didn't know whether to believe it or not. Anyway, he didn't continue this topic, but asked: "What is that thing Xu Lin is sitting on? Why does it look so strange?"

Liu Tan thought that Liu Che hadn't noticed, so he immediately said, "That's called a wheelchair. Father, do you remember the ice cart? Basically, the skates under the ice cart were replaced with wheels. Xu Lin's eyes can heal, But those legs can’t be healed. I asked him to give lectures in the academy before, but he refused to go because he was carried in and out in violation of the regulations of the academy. a wheelchair so that he can move around on his own."

Liu Che glanced at Liu Tan, and he knew that this kind of thing must have been made by Liu Tan.

At this moment, Liu Che seemed to understand why people like Huo Guang and Jiang Chong were so devoted to Liu Tan. His son was really confused when he was confused, but he was really at ease with his own people.

Just when Liu Che was thinking about this, he heard Liu Tan say: "Father, my son has already prepared some wheelchairs. As far as I know, many veterans were injured on the battlefield or got old because of injuries. It is inconvenient to walk due to illness, so when the emperor goes back, take these wheelchairs back or give or reward them."

After hearing this, Liu Che teased him and said, "That's what I rewarded, but no one may remember you, the king of the north."

Liu Tan took it for granted and said, "Isn't the son's son's father's emperor's?"

Why does he want those people to remember him?Although Liu Tan's excuse was military generals, in fact, it is not only military generals who are inconvenient to walk when they are old. What's more, the distinction between civil and military in the Han Dynasty is not so clear, at least not like later generations.

This is a long time in Taiping. If you push forward a few decades, many generals have been on the battlefield.

Anyway, the people who can give Liu Che a wheelchair are not ordinary people. If it is a prince with ulterior motives, he will definitely choose to please them, just like Liu An, the king of Huainan back then, but Liu Tan is not, he just wants to nest in the northern border country Three points, so this favor should be given to Liu Che.

Liu Che didn't need to think too much about what Liu Tan was avoiding. He was more dissatisfied with Liu Quyu while feeling at ease. After all, this prime minister has been in office for two or three years, which is not a long time but not a short time either. It doesn't seem to be a problem to change, as for the reason for the change... It's a joke, does a powerful emperor like Liu Che need to find a reason to change his courtiers?

What's more, the embroidered clothes envoy had a lot of black information about Liu Quyao. Seeing that his surname was Liu, Liu Che would give him a reason.

Liu Tan didn't know at all that Liu Che had already planned to change the prime minister. He was taking Liu Che for a stroll on the grassland, and he said as he walked, "Maybe this piece of grass can be planted after a few years with water. It is a crop that is more cold-resistant and does not require too much land."

After hearing this, Liu Che looked around and felt that if such a large grassland was really used to grow food, then the granary of the big man would not only be in the area of ​​Qi.

Liu Tan thought the same way. When a gust of wind blew, all the green grass was blown to his waist. He suddenly remembered that animal husbandry also occupies a place in the northern border country, so it is impossible to turn all the grasslands into farmland, and for the sake of the environment Think about planting trees.

In this way, the planning of the entire northern border country needs to be carefully planned.

Thinking about this, Liu Tan suddenly saw a few black spots not far away, and couldn't help squinting his eyes and asked, "What are those in front?"

Liu Che also looked over, at this time Lu Xuan suddenly said: "It's a pack of wolves."

"What? Wolves?"

The team panicked for a moment. A single wolf was nothing, but a pack of wolves was a huge threat. Even with so many of them, if they were not careful, they might overturn.

The officials brought by Liu Che were a little nervous and hurriedly said, "Your Majesty, retreat to the camp."

Liu Che didn't speak, and his expression was a little dignified. At this time, the wolves seemed to have found their prey and were running over at a high speed.

He said, "It's too late."

Liu Tan subconsciously wanted to hold the bow and arrow in his hand but found nothing. Then he remembered that he didn't intend to hunt when he came out this time, so he didn't bring out the bow and arrow at all.

Fortunately, the elite group he brought out had bows and arrows on them, so they turned their heads and shouted, "Form up!"

The elite group he brought out this time has a total of 200 people, and they are all equipped with the best equipment. It should be no problem to deal with these wolves, at least it is no problem to scare them away.

As a result, he had just lined up on this side, and Lu Xuan had rushed out with a dozen of his guards on the other side. When the horses were galloping, the Wusun people headed by Lu Xuan bent their bows and set arrows, their waists and legs were steady. no.

Lu Xuan and the others seemed to be running without any rules, but everyone's shooting range happened to cover each other. After a round of volley, the wolves who ran in the front suddenly fell down.

At this time, the wolves already had the intention of retreating, but it would take time for them to turn around and run away. At this time, Lu Xuan aimed at the leading white wolf among the wolves, and it was almost impossible to shoot with a bow and an arrow. In one go, the white wolf wailed and fell to the ground.

At this time, Liu Tan's elite group had already rushed over to form a siege with Lu Xuan's men.

So none of the wolves ran away.

Lu Xuan got off his horse and looked at the white wolf, gestured for someone to put it away, turned around and ran back with a smile: "The fur of that white wolf is good, I'll let someone tan it later... Wear a fur coat, Your Majesty."

When Lu Xuan aimed at the white wolf, his first thought was that he could make a fur coat for Liu Tan before winter, and white fur coats are very rare these days.

The white fox is an arctic fox, and there are none in Dahan, unless you trade with people there, but even Liu Che doesn't have many bodies, let alone others.

And the white wolf's fur is not the same as that of the white fox. The white wolf's fur has a silvery feel, which looks better.

Lu Xuan had already imagined how good-looking Liu Tan would be wearing it, so he was ready to come back to claim credit for Liu Tan, but when he saw Liu Che, he had no choice but to turn around and dedicate the white wolf skin to him. Liu Che.

Liu Che glanced at Lu Xuan with a half-smile, and instead of trying to expose him, he praised: "King Wusun's subordinates are indeed brave men."

Lu Xuan said embarrassedly: "They don't know anything, so they have some skills in riding and shooting."

Liu Che said: "It is also a skill to be able to go to the extreme in this way."

Liu Tan nodded seriously, and then said to the elite group who came back after cleaning up the battlefield: "It seems that you have been a little lax recently, go back and practice more."

Everyone in the elite group froze there, feeling quite at a loss for a while.

Liu couldn't talk much in front of so many people. If he was alone, he probably would have started training.

Look at the people under Lu Xuan, even the harnesses they use are the most primitive. The elite regiments use the best weapons and utensils one by one, but they are always overwhelmed by Lu Xuan's men. This is the result of careful training, Lu Xuan He won't train soldiers like him in a comprehensive way, and there is no second kind of military training like this in the whole world. Where does this make him put his face?

The elite regiment came over one by one, and Liu Che reached out and touched his son's head and said, "Okay, King Wusun's subordinates are all warriors, and your elite regiment has never been on the battlefield, so don't treat them too much." Too harsh."

Liu Tan took a look at the listless boys and sighed: "We've conducted confrontation exercises many times, what went wrong?"

After hearing this, Liu Che asked, "Confrontation exercise? What is that?"

Liu Tan explained: "It is to simulate different terrains and different situations, and then divide the team into two groups to fight against each other to see which side can win. This will test the quality of the soldiers and the general's ability. Interested minister, go back and show Fang Lue to you."

This kind of confrontation exercise was completely unheard of by Liu Che, and no one had ever thought of it before.

After all, these days there is no concept of transfer soldiers, how could they think of specialized training for combat?There are only a few elite soldiers and strong generals, so since ancient times, battles with fewer victories and more have been praised, because the essence of fighting these days is the number of people.

Although Liu Che didn't think it was suitable for a big man to do this, he was still very interested in this confrontation exercise.

Liu Tan looked at his expression and added: "Otherwise, I will arrange a confrontation exercise first, and the father will take a look first."

Liu Che readily agreed, but the soldiers of the elite regiment behind Liu Tan instantly turned pale. Compared with confrontation exercises, additional training is nothing.

At this moment, a rush of horseshoes was heard, and after a while, a little eunuch ran over and handed a bamboo pipe to Bu Fan.

Bu Fan hurriedly sent it to Liu Che. After Liu Che took it, he glanced at it, looked up at Liu Tan and said, "He's caught."

Liu Tan was stunned for a moment: "Who?"

Liu Che's face darkened, he gritted his teeth and said, "The person who spreads the ballad behind his back!"

Can this little bastard grow up?
