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

To say that Liu Ju is also a man with big brains. In history, when Liu Ju rebelled, he had no soldiers in his hands. What did he do?He asked people to run to release the prisoner, and issued weapons to the prisoner.

So in fact, the use of prisoners was not invented by Liu Tan.

But... At that time, Liu Ju was using those prisoners as knives. Who would have thought that this prisoner would be sent to do farm work?

It took Liu Ju a long time to react: "Then...those prisoners...doing well?"

Liu Che took a deep breath: "It looks good."

Liu Ju reluctantly said: "Since that's the case, you can't blame brother if you act in a hurry. As long as brother doesn't let them go, it's fine."

Liu Che glanced at Liu Yi and said, "That's not what I said before."

What I said before is that Changyi King Liu Wei used to make fun of the condemned prisoners. How can he make fun of it?It is to put two condemned prisoners in a cage and let them fight, and the winner has a chance to be exonerated.

It sounds absurd, how can these murderers be exonerated just because they won?

In fact, not many people survived.

It is inevitable to be injured during the fighting, and Liu Mao occasionally gave them some weapons to enjoy watching.

Those weapons are generally bronze knives that are almost scrapped, rust is the most basic, and some are even brittle enough to break with a little force.

In this case, the distribution of weapons is not particularly fair, but what Liu Mao wants is not fair, and he also finds this randomness quite interesting.

Therefore, it is quite normal for wounds to appear during the fighting. These death row prisoners who were injured by Liu Mao would definitely not be healed. In this case, the hope of survival is already small, and those rusty weapons have touched the wounds.

Hehe, do you know about tetanus?

When this matter spread to Chang'an, both Liu Che and Liu Ju were very unhappy.

They didn't think there was any pity for those prisoners on death row, but they were dissatisfied with Liu Mao's bloody hobby.

Liu Ju even said: "I think he's just too idle. This vassal king is really easy to do. I'll see if he has the face to do this when the tax revenue of Changyi Kingdom is overtaken by the Northern Border Kingdom."

It was because of Liu Che that he said that, after all, he was using prisoners.

Liu Ju argued: "They are different. Brother, there is nothing he can do. If not, he would never use those prisoners. It is not easy to let these prisoners do farm work and be under strict supervision. .”

Liu Che didn't speak, but said in surprise, "He even got a harvester?"

Liu Ju regained his spirit immediately after hearing this: "Where is where?"

What Liu Tan makes may not be very fun, but it must be useful.

Liu Che turned his head and said to Bu Fan: "Tan'er said that he will send a model, let's take a look first."

The real prototype is impossible to carry out. The crops are all harvested. Where can I find something to experiment with, so I have to look at the model first.

Needless to say, Liu Tan made this model very well. It is a whole model plate, with a well-planted lawn and a miniature harvester on it.

By the way, Liu Tan also explained in the letter that the effect of the lawn does not represent the crops, it is just for demonstration.

It was the first time Liu Che saw such a miniature farm tool model, so he couldn't help picking it up and looking carefully from top to bottom.

Liu Ju walked over to him, squatted beside him and tilted his head to look at it, and asked in surprise, "Why is this disc intertwined?"

Liu Che said: "This disc should be a cutting knife. It is scattered up and down, not really canine teeth, but... this reel is quite interesting."

After Liu Che looked at the appearance, he put the miniature agricultural tools on the model plate, and Bu Fan who was beside him immediately reached out to push the harvester.

Liu Che and Liu Ju tilted their heads together and looked at the reel on the harvester as it moved forward and opened and closed reciprocatingly, bringing the grass together and sending it to the cutter. The gear-shaped cutter was very sharp, almost instantaneously Cut the grass.

After this trip, Liu Che and Liu Ju looked at the bald lawn on the model plate, and then looked at the small bag behind the harvester. After reaching out and touching it, Liu Ju said with some uncertainty: "This seems to be much more convenient."

Liu Che nodded, but he wasn't too sure.

The annual Xiannong ceremony is to go to the field to drive the oxen to plow the field, and what happened after that has nothing to do with Liu Che. He doesn't know how the people harvest the crops, or he has heard of how the harvest is done, but he has never seen it. .

Liu Che thought for a while and said, "Go and call Da Si Nong to come over."

When Sang Hongyang came over, he had already checked in advance, knowing that it was the letter from the King of the Northern Territory, so he began to wonder if His Majesty wanted to help the Northern Territory.

It is not a new thing for the emperor to agree with the Northern Kingdom to attack the Cheshi Kingdom. Sang Hongyang pays more attention to the situation in the Northern Kingdom than anyone else. After all, his son is still there.

So the number one economist at the time made calculations and found that the grain and grass in the northern border country might not be enough. Soybeans can be used as grain and grass reserves, but when they really go out, they all rely on soybeans to go bad.

Sang Hongyang felt at the time that the king of the northern border would definitely ask for help if he went on an expedition, so he had counted the situation of the granaries closest to the northern border country before, and could transfer grain to the northern border country only after His Majesty the emperor gave an order.

Sang Hongyang was actually a little worried about this matter. What he was worried about was whether the king of the northern border would start fighting non-stop if he found out that he had a big man as his backing in the future.

Although he looks mild, he is Liu Che's son after all. The economic situation of the Han Dynasty has been bad these years, and their Emperor His Majesty began to switch to the policy of Huairou.

Back then, when His Majesty the Emperor was at Liu Tan's age, he also started fighting at the slightest disagreement.

Sang Hongyang wanted to make suggestions but didn't dare, so in the end he could only reluctantly comfort himself that the reason for this expedition was that Che Shiguo's geographical location was too important.

But what he didn't expect was that after arriving at Weiyang Palace, he saw the emperor beckoning to him in a good mood and said, "Come on, Da Si Nong, the King of the Northern Realm has made another new thing, which looks very useful. "

Sang Hongyang was taken aback, new thing?

He walked over to take a look, and before he had any doubts, Liu Che glanced over, and Bu Fan who was beside him immediately asked the little eunuch to introduce the harvester.

Sang Hongyang looked at the harvester with a curious face, and even reached out to push it. I have to say that this model looks really easy to use.

However, he is a more pragmatic person after all. Even so, he still said: "I don't know if the northern border country has already put it into use? Although the model is easy to use, it may not be so good to actually make it and put it into use."

Liu Che said: "This is nothing to worry about. It's not the first time Tan'er has done this kind of thing. How could he not understand this kind of thing? The northern border country has already used it, but it's just because the northern border country The Southern Autumn Harvest came early, and he came up with this thing because of the lack of manpower in the northern border country, so he didn't rush to send it over."

While listening, Sang Hongyang took a document handed over by Bu Fan, which had recorded in detail the service life of the harvester, as well as various parameters and drawings.

I have to say that most people in this era may not be used to Liu Tan's way of recording everything in detail, but I have to say that this way is really easy to use.

Later generations, whether archaeologists or historians, must first set the tone of speculation when investigating materials, and then demonstrate the meaning of this sentence through different directions.

Not for anything else, just because people these days speak so frankly and succinctly!

However, there were not as many characters in ancient times as there are now, and many of them were fake characters. Sometimes it was right for one meaning, and that meaning was fine.

Of course, Liu Tan knows that this may have something to do with the bamboo slips in ancient times, and it is inconvenient for everyone to use a carving knife.

Later, although there were pens and inks, they were not affordable by ordinary people, let alone blank paper, a piece of blank paper was so expensive, of course, when writing, we should cherish words like gold and write as many words as possible.

This means that it cannot be used in both directions, but if it can be used in both directions, someone will definitely use it that way.

But Liu Tan doesn't lack these things, so he would rather spend money to have people record them in more detail than to let future generations guess, after all, he has really suffered.

As for whether historical materials will be lost, Liu Tan can't guarantee that, who can predict natural disasters and man-made disasters.

It has to be said that his method has not yet benefited future generations, and the current generation has experienced this benefit first.

Basically, according to this document, it doesn't take much effort from the people below, and it also saves Sang Hongyang a lot of worry.

You must know that in the past, it was done according to the drawings of the Mohist school. If there was a need to change the drawings, it had to be reported layer by layer, and no one dared to change it easily.

Sang Hongyang couldn't hold back and said with emotion: "It's still the detailed drawings of His Royal Highness the King of the Northern Realm. If they are all such drawings, I can rest assured."

Liu Che slightly hooked his lips: "He is just too careful."

Sang Hongyang looked at Liu Che's unconcealable pride, and the undisguised look of the prince beside him, but he didn't say anything after thinking about it.

The things sent by the King of the Northern Territory are really good. Sang Hongyang even thinks it is good to send them at this time. After a year of preparation, most areas will be able to use them by next autumn harvest.

There is plenty of time for production. If it is delivered before the autumn harvest, arrange it immediately. If the time is too late, if you don’t arrange it, it will make people anxious if it doesn’t work.

Sang Hongyang sensed Liu Che's pulse, and began to say good things without money.

Anyway, if it was other princes and kings, Sang Hongyang might not be able to boast, and it is not bad to praise the king of the northern border!

The smile on Liu Che's face widened a bit, and he thought for a while and said, "When we pass by early next year, we may be able to see the current farming situation in the northern border country."

Sang Hongyang was stunned for a moment: "But...Your Majesty, didn't you say that you will go on an east tour next year?"

Liu Che was slightly taken aback: "Huh? Did I say that?"

Sang Hongyang: ...
