Chapter 468 is good, isn't it?

Li Jiancheng saw the hint from Li Yuan's gaze, and Li Yuan silently asked Li Jiancheng not to say more.

Li Jiancheng's heart was warm, and it felt good to be protected by his father.

Just when Li Yuan opened his mouth and just said the word "Majesty", Yang Guang saw Li Jiancheng coming, and there was a smile on his face:

"Da Lang, I heard Pei Qing say that you have the idea of setting up tools, and you are even thinking about improving the plow, let's listen to it in detail."

The reason why Yang Guang had a cold face just now was that Li Jiancheng came up with this idea, Yang Guang thought of the civil and military affairs of the Manchu Dynasty, but he didn't come up with a decent solution, he only knew how to throw the pot......

He felt that even if he was not wrong, he would spend money on this group of waste, mainly because this waste also made a teenager who had no official body and did not reach the crown to compare.

This made Yang Guang feel ugly on his face! After all, these officials were appointed by him. Doesn't this mean that you have a problem with your vision?!

In addition, when Yang Guang asked Pei Hongce where there was a problem with the current agricultural plow and what was good about the improved agricultural plow, Pei Hongce said hesitantly.

Li Jiancheng only said the parameters roughly, Pei Hongce knew that it was feasible, but he didn't see the real thing, even if he had already composed a picture in his head, but how to explain it to Yang Guang, a layman!

What's more, Yang Guang did not have a long face and joy as Pei Hongce thought, but because after he said the solution, it was so yin that it could drip water, which made Pei Hongce even more afraid to speak casually.

After all, Gao Ying and the others were cut off by Yang Guang very neatly.

Pei Hongce really couldn't figure out if Yang Guang would suddenly burst out, and then click him too.

Before, he was frozen like a dog outside, but when he came in, he was scared, and his face was good-looking.

Li Yuan raised his eyebrows, what is the situation, why did Yang Lao Er laugh when he saw Li Jiancheng?

Li Yuan silently looked at Pei Hongce, who breathed a sigh of relief, Pei Hongce understood in his heart that Yang Guang was very interested in Li Jiancheng's proposal, but his answer just now did not satisfy His Majesty, not to mention that he "invited" someone from the queen's palace!

But he couldn't say this, Pei Hongce gave Li Yuan a slightly calm look.

Li Yuan immediately understood that Yang Guang was only targeting Pei Hongce, as long as Yang Guang did not involve others and the problem was not big, then there would be nothing.

The small movements between Li Yuan and Pei Hongce in a flash, Yang Guang and Li Jiancheng both saw in their eyes, Yang Guang was used to it, whenever he looked up and down, the officials below were flying with their eyes.

Li Jiancheng said secretly, it seems that he has to have a pair of "talking eyes" when he comes to be an official.

After the flash, Li Jiancheng immediately nodded and responded:

"That's what the grass people think." Yang Guang motioned to Li Jiancheng to continue with a serious face.

Li Jiancheng groaned slightly, and then typed a draft:

"The plough we are using now is the appearance of the Han Dynasty, there are double and single wheels, basically two oxen carrying type, especially suitable for use in the plain area, can ensure that the field plough is straight, easier to control, and the efficiency is also higher, but it did not spread when it appeared, until the Wei, Jin, Southern and Northern Dynasties period, I knew the benefits of the plow, and it was widely used.

But the plough is generally about 9 feet long, reaching the shoulder of the ox in front, not to mention the weight, but also rotating. Therefore, it was changed to a curved plough that could be pulled by a cow.

Except for some plowshares, which are made of wood, although they are easy to wear, if some structures are replaced with iron, the speed is faster. ”

Speaking of this, Li Jiancheng stopped talking, and stood there with his eyes, nose, nose, mouth, and mouth.

Yang Guang calculated the account in his heart, the work that was originally done by one or two cows can now be replaced by one cow, and in the same time, it can be at least twice as fast.

It's just this iron ......

Yang Guang thought about it:

"Do you know the importance of this iron?!"

Li Jiancheng nodded and said:

"I know, but I know even more, people use pots for cooking and knives for cutting, so the main question is not iron, but what this iron is used for."

Now there is a shortage of mineral products, after all, copper is now used to mint five-baht coins, and copper itself is lacking, and the productivity and scale have been increased, but the output is not enough to consume and use.

The army needs weapons, and the amount of iron ore is also very large, so it is the basic reason to avoid excessive consumption of iron, and of course, there are also ways to prevent others from privately casting swords.

But in fact, what is restricted is only crossbow arrows and other things, think about the ban on guns, which is almost what it means.

Yang Guang raised his eyebrows, as if he was moved:

"Have you ever wondered how much iron you'll need?"

Li Jiancheng immediately replied:

"There are more than 6 million households in the state, and it is impossible for every household to use a domestic plow, and there are five or six households with a foot, or even a dozen or so households with a frame. The people in the village are all of the same clan and clan, after all, they can be borrowed.

If one million is sufficient, and the plough is insufficient in the early stage of iron ore, it is possible to replace only the plowshare with iron, instead of all iron, it can be clad with iron. ”

Although Li Jiancheng did not give a specific number, Yang Guang already had a number in his heart, even if he changed the plow, it was impossible to change it all at once, after all, it still had to be produced.

Yang Guang felt that he could still squeeze out some iron ore at hand, after all, the people take food as the sky, and the more food, the better, thinking of this, he said:

"But if you change the plow, what if those who have a plow now insist on using the original one? After all, it's a big expense. ”

Li Yuan secretly benefited in his heart, and felt that the stupid question asked by Yang Lao Er had already been thought of by his son.

"Don't sell it, let the county rent it." Li Jiancheng is calm and authentic.

"Rent? What do you think is right for the price? It's too expensive, but you won't be rented, and if it's too cheap, how long will it take to get back to your capital. Yang Guang felt that Li Jiancheng was still too young, but he could think of this convenience, which showed that he was also very attentive.

However, Yang Guang planned to change the plough, after all, it could save strong labor.

Li Jiancheng Bao naturally said the number with Li Yuan:

"One percent of the price of a plow." He didn't ask for orders at the moment to talk about it, he wanted to take over.

"It's cheaper." Yang Guang clapped his hands and said:

"Your idea, though, is a solution. Tomorrow, Lonely and the courtiers will discuss how to carry out it. ”

Li Jiancheng did not argue, the price of one percent is not cheap, this price is almost a water collar, no matter how expensive it is, no one wants to rent it, after all, there is an old-fashioned plow at home.

Yang Guang was very happy, after all, this was a reliable solution, and he couldn't hear the emotion when he looked at Li Yuan's voice:

"You're good today...... bar. "I also know that I am protecting my son, and it is so difficult that I will eat him?!

Li Yuan was very surprised in his heart, even if things were done well in the past, Yang Guang also praised himself, today he just brought some essential oils, how could he get a compliment, but what does that "bar" mean?

If you don't want to boast, you don't have to say it!! (To be continued)
