Within a few days, Li Er quickly sold the carpet and the soft chair, that is, the manufacture of simple sofas, which was not mainly to sell technology, but to collect taxes.

If you don't pay taxes, then you don't want to do this project, you know, these two are high-consumption products, and they are also necessary products for some families.

What, it's easy to learn, carpet, isn't it just two wood rollers, and hooks, this can be used to weave carpets, and you can also use some inferior wool threads.

The most interesting thing is that the woolen thread cut from this carpet can also be used to make mats and sell them to some medium-sized families to make beds.

This kind of mat is terrible, although it is a little prickly, but as long as a layer of animal skin mat is spread on it, there is nothing, no matter how cold the winter, the more you sleep, the warmer.

That is to say, the entire wool business, or a whole sheep, there is no place to waste, so far, let Yang Qiao make use of it, now, this sheep, but the income of the previous sheep is nearly ten times, this value, it is strange that it is not robbed crazy.

And these businesses, almost, are all flowing out of Li second-hand, what, don't pay taxes, then, if anyone uses these technologies, Li Er has every reason to directly lead troops to destroy the other party.

This is much more powerful than patents, patents, but a group of people together to negotiate a provision to protect their own technology, and a person, even the royal family, therefore, Yang Qiao is disdainful of the patent, and when will each family be able to study technology, and they are afraid of being stolen, and they still want to sell technology, this patent law will naturally appear.

…………

"Daoist Yang, the lower officials are here for help."

It was rare for Yang Qiao to come to the Taoist temple, but as soon as he arrived on the front foot, the official of the Ministry of Industry who was responsible for repairing the road came with a sad face.

"Why, you don't build roads well, why did you come to me, the technology is given to you, the teacher, it is also given to you, what more do you want?"

"Teacher, they said no, they will only build cement roads, not the asphalt roads you said, and they have been testing with us for a long time, but they have not tested it, how to mix this asphalt into cement!"

"Well, gossip, think about me, what the hell did I tell them?"

There are many technologies that have been passed out, and it is also a trouble, at this time, Yang Qiao has forgotten what has been passed out and what has not been passed out.

"Boy, it seems, this asphalt pavement, you really didn't tell them how to operate it, just said that you can mix asphalt with cement and use it!"

"Talkative, it's all your fault, since I had you, I don't even have the habit of taking notes."

At this time, Yang Qiao didn't find fault with himself, but complained about talking, in fact, even when he didn't talk, he didn't have the habit of taking notes.

However, this is all due to people's bad nature, and if there is anything bad, they will press on other people's heads, even if people don't know about it.

"Blame me, blame me, then, don't ask me anything in the future, hum."

The chatter shut up very arrogantly, no matter how Yang Qiao greeted, it was silent.

"Let's go, I'll go with you to have a look, alas, I can't be idle if I want to."

"Lang Jun!"

When Yang Qiao came to the construction site, his craftsmen came to him a little embarrassed, feeling that the task was not completed, and he was very ashamed, Lang Jun taught himself so many things, and he couldn't even do such a small thing.

"Okay, I don't blame you, I didn't expect this asphalt road to teach you, and now, you have done a good job."

It's very good, no, when the official in charge of this road in the Ministry of Works arrived, he was surrounded by a group of people.

"Don't talk about you as a little five-grade official, even if you Shangshu is here, we have to find trouble with him, why did you dig the road in front of us in a mess and let us not walk......"

"Have they always been like this?"

Yang Qiao frowned slightly.

"Yes, Lang Jun, recently, this Chen Langjun has been harassed by them."

"All of you, the people of who's house, give the name of the head of your house."

Obviously, these are some housekeepers, and they look like foxes and tigers.

"You! Eh, Yang Langjun, let's go, let's go. ”

This is?

"Yang Daochang, you don't know, you are on the hero list of Chang'an City, so naturally they don't dare to provoke you, and besides, they have heard about it a long time ago, and they heard that you will not come here, so they are looking for trouble with the lower officials, but in the future, they will not dare to come, but this place does block their way, you see, these wooden bridges are all for them to walk temporarily."

Yang Qiao looked at the scene in front of him, and couldn't laugh or cry, you, since you haven't tested it well, what kind of road are you digging, and besides, you are digging so deep, is it necessary!

At this time, a section of the road has been dug down, and there are two square markets, so it blocks the road at the entrance of the two markets, but it is good, the people who live here, but they are all the same existence, and they also paved a few wooden bridges, however, this temporary wooden bridge is not so easy to walk, and there is, every other distance, there are large piles of stones, sand or something, this is, the materials are ready, but when it comes, they don't know what to do next.

However, why did the craftsman teacher sent by Yang Qiao do this, because, at that time, the cement road was repaired, but the road that transported cement out, the road was relatively strong, because the load was too large, if it was not strong, it was better not to repair, you know, the cement road was broken, and it would be more difficult than the dirt road.

Therefore, at that time, the ground was paved with a thick layer of gravel of different sizes, stones, and then, on top of it was paved with cement and gravel and sand mixed concrete, this is the cement pavement, which is really strong enough, if Yang Qiao is not worried that the cement is not up to standard, he can guarantee that this pavement will not be bad for a hundred years, why is it hundreds of years, this cement, but there is a time limit for use.

And now, the craftsman has naturally learned this trick, but to match the height of the railway, naturally, this road surface will be dug down fiercely.

"That's all right, you guys, spread this stone underneath, how deep is it, come here!"

This depth, it's really hard to say, then, can only be designed according to the height of the side rail pavement, and after the stone pavement is paved, it must be compacted with a roller, which is the roller used to press the road, is made of stone, and it needs several people to pull, even with horses, or cattle to pull and press.

After the stone pavement is compacted, a layer of loose sand and cement mixture is paved on it, and after compaction, another layer is come, and then, it is covered with a curtain first, and then watered on it, which is the most reasonable way to build the road in Yang Qiao's previous life, however, no matter how reasonable, it is just technology, with original technology, and with advanced technology, it is a matter of speed, and there is not much scientific and technological content in it, to say that the scientific and technological content is just the standard of cement, and the proportion of sand.

This, to the point is not a problem, I would rather the gray number be slightly larger, too standard, but to save materials, and now, because it is the experimental stage, so, this material, but can not be saved.

A group of craftsmen looked at Yang Qiao with wide eyes one by one, listening to his explanation, while the officials were quickly recording on the side, afraid of falling behind.

"Yang Daochang, but, what about asphalt, you didn't talk about how to use asphalt?"

"Asphalt, well, you go to make a few such big pots, and stoves, this, you don't need me to draw drawings, some of my technical teachers will know, you just need to tell them the size of it, and when your iron pot and stove are ready, then call me, and these things I ordered today, you also have to do them as soon as possible, don't affect people's walking."

There is no mixer or anything, naturally, it is necessary to use the most primitive way, and it is a relatively advanced road repair method to lay the top layer of asphalt cement mixture, so it will use a furnace and an iron pot to melt the asphalt and even mix the cement or something!
