This is the most reasonable use of cement in this era, which is not high in yield.

Yang Qiao looked at the bridge pier made of cement and stones, and was happy, although Li Er did not visit his cement factory, that is to say, the cement road leading to the outside of the mountain was definitely made for the blind man, but it was not impractical, and it was absolutely indispensable.

No, just to test the effect of this cement, one by one, some are very powdery, some are very brittle, and some are slow to dry, in short, there are all kinds of types, and I don't know why, that talk, it didn't help.

However, this also gave Yang Qiao accumulated experience, especially after a few rains, he was more sure of several formulas.

Perhaps, this is the real purpose of the chatterbox, which is to let Yang Qiao get several more formulas, and there is only one formula it can provide, and it is a relatively advanced kind, it seems that it is really not practical, and the price is also high, and it is difficult to fire.

"Okay, haha, okay, that's it, Wang Qing, according to this standard, first build a wooden bridge on each of the main rivers in the city, and then you will discuss how this bridge should be arranged."

Wang Qing, an official of the fourth grade, was newly established under the Ministry of Industry, and Yang Qiao provided a new idea of an official in charge of craftsmen, because it was temporary, Li Er had not yet been officially confirmed, so there was only a rank, and there was a duty, but no formal official title.

However, Yang Qiao thinks that this department is well set up, perhaps, in the future, some craftsmen who can't get ahead will be collected by the Ministry of Industry, and all of them have levels, although the level is not high, but it is also an official.

This is definitely an idea to put wings in, but, in the court, there are still debates, Li Er, there is still trouble, although the system of six ministries in these three provinces has not really been formed for a long time, but a batch of old antiques is already there, that is, vested interests.

And these craftsmen, all along, have been in the third class, Shi Nong Industry and Commerce, this time, it is strange that it has been raised so high, and no one objected!

"Shengshang, this bridge, I still recommend waiting a few days before going to the people, but now you can let the craftsmen start painting, and when you can really go up to the people and bear the weight, the paint will be dry, but the maintenance of this bridge, it seems, there is still a need for a special maintenance team."

"It's easy to say, I'll leave it to Jingzhao County to be responsible, what do you say."

Li Er said to an official.

"The minister obeyed the order, and immediately went back to set up a Chang'an City bridge protection team, which was originally the minister's responsibility."

It turned out that this was Jingzhao Shaoyin, Yang Qiao thought that this was an official of the court, and it turned out to be a magistrate, but it was just at the feet of the Son of Heaven, and this official was not easy to do.

"Shengshang, let's go down the bridge, this is still a bare bridge, and I'm worried that the piers at both ends can't stand it temporarily, and after a few days, the bridge can really be built and can be passed, as long as it's not a particularly heavy object, you can still come up."

"Particularly heavy?"

"Well, like a cart of sand, a cart of stones, and others, such as grain, lighter than grain, and even running horses, can pass through the bridge, and if you look at the bridge again, the piers on both sides can not only be played here, but even the boatmen of the Nara can pass through the piers."

These water conservancy facilities in Chang'an City, especially several artificial canals, were built for shipping at the beginning, naturally, at this time, Li Er planned to use them, otherwise, he would not have seen this wooden arch bridge, so interested.

"Boy, that cement, I didn't expect it to be as good as you said, you see?"

Here in Li Er, and even in some old killers, Yang Qiao's two-word title of kid, it seems that he will be called for a long time, Li Er, qualified to be called, in general, his daughter was given to Yang Qiao, and the others relied on the old man to sell the old man.

And there are still people, come on, set up a rule, after this, you really need to have a suitable Taoist robe, and the title of the province is also messy, what kind of instructor or something, just call the Taoist chief.

Speaking of the Taoist.

"By the way, talker, I promised the prince to see me in ten days, and now, a few days have passed, and this day has passed."

Recently, Yang Qiao has discovered a new use for chatterbox, that is, to use it as a calendar or a clock.

Like, chatterbox, what time is it?

"Back to the host, it's Datang time, three minutes and two minutes."

This time is still relatively accurate, and this kind of answer is still very standard, and there is no joke at all.

"Back to the host, there are still three days left before the time you agreed with the prince."

This can even be used as a notebook.

"Boy, host, I beg you, in the future, don't ask me about the time or anything, this way of answering is too embarrassing, too ......"

"Haha, I didn't expect that you are talkative, and there is this day, I know how to toss you, save you from tossing me, and I have nothing to do with you."

Yang Qiao knew that when answering the question, it seemed that when answering the question, it was taken the initiative by a clock system, so it thought it was more uncomfortable.

"Holy one, then, the little one has retired."

Small, when did Yang Qiao be so careful in front of Li Er, as soon as Li Er heard it, his heart tightened, it seems that that thing is coming, as for the result, alas, look at the development!

"You, this, well, you go, I still need to study this bridge!"

A bare bridge, what is there to study, not only is it difficult to get on and off the bridge, but also at both ends of the bridge, there is still excavated soil, which has not been treated, at this time, that is, a few people come up, as for the horses, don't even think about it.

"Boy, maybe, I can give you a simple one, isn't this paving the road and building a bridge, maybe, you can suggest Li Er, start building sewers, haven't you been worrying about the sewage problem, now, with cement, isn't it a good solution."

"Well, this is also a way to make cement pipes, and this kind of pipes don't need to add steel bars, just use some bamboo chips. That is, the amount of cement used in this pipeline is not very small. ”

"That's why you have reached the level of ten tons a day, you think ten tons is a lot, but it's just two hundred bags."

"Yes, look at the bag, it's really not much, but, look at the mill, it's not much, it's less, but it can't be grinded, how many donkeys do I need to raise, and I have to give them masks or something, you say, donkeys, wear eye patches, it's enough, you put a mask on it, can it be comfortable! You see, those donkeys who are pulling and grinding are jumping up and down, I have never seen such a lively donkey pulling and grinding. ”

"You don't need a mask!"

"You think I'm stupid, it's good to choke a donkey to death these days or delay some efficiency, I don't know!"

The dust, absolutely, Yang Qiao went once, he didn't want to go a second time, fortunately, a distance away from the mill, there was no dust, but the workers Yang Qiao was looking for were dedicated and didn't complain at all.

However, Yang Qiao's treatment for them is also high, protection, dust glasses, masks, after work, there is a hot bathhouse to take a bath, and even, even soap, are equipped, they really don't have many opinions, for this reason, Yang Qiao doesn't want to spread this cement plant out, it's just harmful.

"Qingfeng, Mingyue, recently, what kind of Taoist people have placed orders here?"

"Looking back at the Lord, there is none, only the neighbors on the left and right, occasionally come to sit, and then, or Sun Lao Immortal again, some time ago, also left, saying, come back in a few days, see that the Lord is busy, so, did not say goodbye to the Lord, Immeasurable Heavenly Venerable."

These two Taoist children have also learned a good way, here, it seems that there is something missing?

"Ah, by the way, alchemy furnace, chatter, this, will you make it, this Taoist temple, without the alchemy furnace, how can it be called a Taoist temple!"

"This, I can provide the drawings, but, what are you doing with that kind of harmful thing?"

"Who said that refining harmful things, I can't use it to boil medicine, you don't know, if you use an alchemy furnace to boil medicine, I estimate that this disease will be three points better without medicine."

"Yes, you know a lot about medicine in your heart, but don't rely on this completely."

"Since there are Sun Shenxian who often come, and there are Taoist doctors in those classics, can you make good use of it, besides, these two boys, it is good to give them a foundation to stand on, during this time, the inspection of them is considered to be more than qualified."
