"Didi ......"

Hearing this voice in his head, Yang Qiao was very irritable at first, not happy, why, this reward is too fucked, what Yang Qiao needs, can't come out, it's out, temporary, and it may not be able to be used, although, the words that have come out are all useful, but, until now, what is the excavator, Yang Qiao has never come up with a use.

Isn't it, you also rewarded me with an excavator, but, you rewarded, do I dare to use it, how to explain, what, God rewarded me, but, where does the diesel come from, then, I can create a modern chemical system.

"Congratulations to the host, reward the principle of the design drawings of the wooden arch bridge, and a copy of the calculation data."

Yes, as soon as Yang Qiao was distracted, the reward came down, as if, he felt that he had heard something incredible, but why was he distracted, why was he distracted, what the hell is this wooden arch bridge?

"Congratulations to the host, congratulations to the host, your reward, but it's amazing, although it may not be able to make money, but this is a good inheritance building, and it is the most needed building in Chang'an City now."

"Ah, that, what do you mean, it's just a kind of wooden bridge, and it can't be loaded, and it can't be anything."

Yang Qiao didn't believe what he said, and now, he really didn't want to do something extra, he was mainly preparing for next year's battle, but what he meant was that now, he could start to make this bridge, and he would do it in Chang'an City.

"Boy, haven't you noticed that there are a lot of rivers in this Chang'an City, but have you seen any beautiful bridges? Sao Nian, the responsibility of beautifying Chang'an City in the Tang Dynasty will be handed over to you, aren't you excited, don't you feel a great responsibility? ”

This is a problem, when did you learn to sensationalize, but, too, in this Chang'an City, there are really a lot of large and small rivers, and there are also a lot of large and small stone bridges, wooden bridges, and even bamboo bridges on the rivers, but there are not many really beautiful appearances, why, Chang'an City was built too anxious, there are some things, it seems, it is not too perfect, although the stone arch bridge, it seems to have appeared decades ago, but this technology, no one necessarily has learned, at least, at this time, Yang Qiao has not seen any stone arch bridge.

"Boy, are you thinking about the stone arch bridge, don't think about it, that, dealing with stones, it's too complicated, and the hook inside is also more complicated, and the manufacturing is also complicated, so, I suggest, you still build from this wooden arch bridge, this wooden arch bridge, not only beautiful, but also very strong, that is, the life is not long, this wood will rot, so, this lifespan, it would be good to have fifty years."

"If the life span is so short, why do you still ask me to build this kind of bridge?"

"Why, the most famous bridge is the Zhaozhou Bridge, that is, the bridge built by Li Chun in the previous decades, during the Kaihuang period, but what you don't know is that the most beautiful is the Hongqiao on the Qingming Shanghe map, that is, it is the wooden arch bridge."

Well, Yang Qiao is a little lonely, he knows the Qingming Shanghe map, but he doesn't know what is in it, especially that there is the most beautiful wooden arch bridge inside.

Sure enough, Yang Qiao flipped through the memory, this new memory, this wooden arch bridge, is really suitable for this era to use, even, this wooden arch bridge, is not worse than the bridge made of fired cement in this era, even, the steel bridge of this era, even, the life span will be stronger than them, this, is a technical problem, not bad, so, this system, sometimes feels, is still powerful, some things, or in order to be good, but, I don't know why, this wooden arch bridge, will come later than the stone arch bridge, well, I'll correct history, although this stone arch bridge appeared, but it is not yet famous, so let's make the wooden arch bridge famous first.

Wooden arch bridge, not simple, take the Bianshui Hongqiao in the river map as an example, the bridge is 16.8 meters long and 4 meters wide.

Moreover, this wooden bridge can be used in the fastest time to make some of the most beautiful decorations, and, once the construction is reasonable, in this Datang, it is enough, whether it is load-bearing or other aspects, it is not bad, that is, it is not durable, but it is cheap.

Even, once more bridges are built in Chang'an City, some new carpenters can be trained.

In fact, in Yang Qiao's heart, this bridge is not important, perhaps, the number of carpenters is what he cares about the most, especially the carpenters that appear on these high-end buildings.

In short, it is not important to carve beams and paint buildings on the house, and it is not something that ordinary people can use, but this practical advanced carpentry technology is what the entire Tang Dynasty needs, and perhaps, there will be some mathematical talents from it.

Therefore, Yang Qiao decided, the pre-war preparations, he can pay attention to it every day, and this wooden arch bridge can be regarded as the current focus, and there is no need to find a place, whether it is a home in the countryside or a home in Chang'an, there is a river, and this wooden arch bridge can be erected on it.

Moreover, once the construction of the wooden arch bridges in these two homes is completed, a group of craftsmen can be trained, and it is estimated that without Yang Qiao opening his mouth, someone will take the initiative to ask for help.

"Boy, what have you been doing lately, I heard that you demolished the bridge at home and started building it again, don't you want to take them to battle."

No, Yang Qiao is not in a hurry about training, Li Er is in a hurry first, it seems that the battle at the beginning of next year, in fact, at this time, Li Er may have been prepared in his heart, and even, perhaps, he has discussed it with Li Jing and others, that is, he doesn't know how to arrange Yang Qiao.

Or, since Li Jing praised Yang Qiao, Li Er has any new ideas about this training camp, and he is also anxiously waiting for Yang Qiao's battle, it's a big deal, let Li Jing take care of it more when the time comes.

"Shengshang, this training, in fact, doesn't need me to take care of it too much, as long as I lead the way, I don't need to be in charge, but this wooden bridge is even more important, when the time comes, you will know the Shengshang."

"Okay, okay, I can't talk about you, you can do it yourself, if the coming year, oh, if in the future, oh, what am I talking about, you, let's go, let's go, I, headache!"

Oh!

Yang Qiao was a little inexplicable, why was this Li Er inexplicably angry!

In fact, there is also an indispensable component of the stone bridge, and even, it is the most important component, that is, the pedestal on both sides, it seems that no matter the bridge of any era, any style of bridge, this pedestal, is the most important, so it is understandable that the stone arch bridge first appeared, and then the wooden arch bridge.

However, fortunately, Yang Qiao finally stumbled and built the first wooden arch bridge, which is this length, not too long, not more than ten meters, it can only be regarded as a small bridge, even if it is small, Yang Qiao has also gone through many load-bearing tests before deciding to officially use this bridge, and, in the future, according to this standard, you know, even in Chang'an City, there are such small rivers, that bridge, there is no need to be too heavy, as long as the galloping horse runs on it, does not step on it, it will be.

In fact, this first bridge did not cause any trouble, naturally, no one in the family appreciated, the old lady, that is a grumpy person, maybe, let her be a general, can achieve something, if you say, let her understand this science and other things, don't think about it, even, even if it is the eldest sister, although it is the first contact with the primitive industry, but her goal is not here, her idea, that is, what the younger brother said, just do it well, no, you can ask the younger brother.

As for the daughters-in-law, not to mention, perhaps, they will be more interested in this bridge railing, beautiful, beautiful, especially the color, how gorgeous, and the pattern carved by Yang Qiao himself, not to mention.

Therefore, Yang Qiao decided to start the second bridge project immediately, that is, the bridge in the city, and he chose a place that could be seen on the surface, so he didn't want to believe it, and no one appreciated it.
