I don't know when, at the southeast city wall of Chang'an City, both inside and outside, a team was actually fortified far away, and I saw that a wooden bridge was erected on the city wall.

And the city wall below seems to have been demolished.

It's either like it's demolished, but naturally, this is the railway connection part inside and outside the city.

Then, what about the elevated wooden bridge above the city wall, Yang Qiao plans to use this wooden bridge as a temporary city wall defender passage, and the other is, perhaps, in the future, this wooden bridge will be a place to watch the scenery, so this wooden bridge, the appearance of the construction is quite gorgeous.

In other words, after this section of the wall is repaired, the wooden bridge will become a wooden bridge completely used for viewing.

To say that this section of the city wall has been demolished for a long time, that is to say, the railway outside the city has been repaired to the edge of the city wall, and it is waiting to be connected with the railway in the city.

"Daoist Yang!"

At this time, Yang Qiao really became Yang Daochang, because, most of the time, he was dressed in Taoist clothes.

"Husband, what are you?"

The daughter-in-law is a little puzzled, why, this husband has been wearing Taoist clothes almost all day recently, and even when he exercises and practices calligraphy, he wears Taoist clothes.

"I estimate that in the future, this outfit will basically not be able to get off, and in the future, I will basically not care much about some worldly things, and the things at home should be slowly handed over to our baby."

"Husband, will it be too early to hand it over to him now, he is still so young?"

"It's not small, after he passes the crown, I will officially hand over the position of the head of the family to him, small, isn't there a housekeeper to cooperate!"

What does Yang Qiao mean?

What does it mean, that is, the construction of the family, for him, has reached the extreme, how can it be developed, now, it is just slowly accumulating, there seems to be a good saying, a noble family, after three generations of efforts, therefore, Yang Qiao's efforts of the first generation have ended, at this time, even if the son is still young, he should hand over the power, not that Yang Qiao doesn't care, but that he will retreat behind the scenes and become the existence of the Dinghai Shenzhu in the family.

However, outside, that is to say, Li Er, as well as Datang, and even the Taoist temple that Yang Qiao took over, since he worshiped a master, then he must fulfill the responsibility of an apprentice and carry forward the mantle of the master.

Therefore, there is no need for Yang Qiao to build the home, but there are many other things that need Yang Qiao, no, this railway is a task.

"Daochang Yang, can this door be suitable, you can see it inside and out?"

"Well, it's naturally suitable, one is to reduce weight, the other is to enhance defense, naturally, when the time comes, the defense will be more troublesome, the bow and arrow outside may be able to shoot inside, and even, inside, it can't be blocked with sundries, here, you must keep the traffic flowing at any time."

"Okay, Daoist Yang, I understand a little, so, do you want to start erecting this iron gate now?"

"Well, the erection is also completed, the concrete pavement below here has been more than ten days, and let the Holy Shang start arranging the guards to defend this railway gate, this should be a separate force."

Naturally, a separate defense force is needed, here, switches, sometimes there will be no things for a few days, sometimes, there will be switches several times a day, here, not walking, but only passing by trains.

No, the pillars of the city wall are almost finished, just wait for this heavy iron gate to be erected, and then begin to encapsulate the perimeter, so that a gate can be considered completed.

The gate is a push-pull style, so at this time, in the city wall, the construction has been completely completed, that is, there is no capping, and the outside column has not been built, and the iron gate needs to be erected before construction, and this iron gate is two, when it is opened, it is first inside and then outside, and when it is closed, it is first outside and then inside.

Naturally, this door is not pushed and pulled by people, but with pulley guides, and there is a separate control room inside, which is controlled by a crank handle.

The door is made of thick iron bars, and the gap between the iron bars is the size of a fist, that is, this iron gate, on the outside and inside, can be placed on a team that defends or attacks with bows and arrows.

However, this door, the doorpost, is quite strong at this time, and no matter how much force you use, you can't hit it.

At the top of the iron gate, there are also guide rails, then encapsulated in reinforced concrete, and on top, there are city walls, battlements, and this section of the city wall, but it is thickened, this thickening, one for the iron gate, and the other for the wooden bridge at the top.

When this section of the city wall is fully usable, this wooden bridge will not go up from the city wall, but from under the city wall, directly set up a wooden ladder to go up, here, will become a place to view, outward, you can watch the beautiful scenery outside the city, to the inside, you can almost look down on the whole city, and the most important scenery is this railway with the double road.

At this time, looking at the past from this wooden bridge, on both sides of the compound road, there are many rainbows of flying frames, that is, wooden bridges, in order to be pleasing to the eye, naturally, it is painted with various colors.

What are these wooden bridges for, this is connected to the compound road from the homes of some families, that is to say, in the future, the ministers of these families will directly go to the imperial city through the compound road, no matter how windy or rainy it is, it will not be affected.

This is considered a welfare package, that is to say, at the level, there will be such a treatment, and what should I do if some people are far away from here?

What to do, Li Er's plan is to build a few more roads in Chang'an City, because he found that this is a good thing, whether it is military or civilian, it is beneficial.

"Daoist Yang Daochang, look, this iron gate has been shipped, how should it be erected?"

At this time, Yang Qiao had to admire these craftsmen, he just said a rough idea, and there was a drawing, as a result, these two iron doors were built like this, and, in the absence of bolts, what, no bolts, yes, Yang Qiao has not yet had the kung fu to manufacture, or professor, this time, all the connected parts are riveted and packaged, or rather, this riveting is as strong as welding.

And the transportation, even more powerful, the newly built train chassis is also used, it is an empty frame, as for the horses pulling the carriage, it actually used twelve horses, this horse driver is also amazing, can command twelve horses at the same time to move within the specified range, and even say that they walk on a fixed line.

"If you don't ask me, how are you going to set it up?"

Yang Qiao was a little curious, if, if there were no pulleys, yes, in front, the iron door was made, and no pulleys were used, but the iron door was made directly on the frame.

"I don't need to ask you, then, I will use the soil cultivation method, or use the skidding method to erect this iron gate, but it will take a long time, but I heard that Yang Daochang, you have the easiest and fastest way?"

"Well, actually, I'm ready, you see, on those wagons."

Yang Qiao pointed to a few special carriages that followed him, why is it a special type, this is a highway type of train, however, the weight is not heavy, it is relatively long, this is a mobile type of pulling rod, this, Yang Qiao is a kind of high density and toughness of wood made of wood in the deep mountains, this, where to go, just put an iron plate on the ground, and then, let the pulling rod frame in a specific position, so, a simple lifting equipment is completed, why not make it into the shape of a crane, Again, it's too heavy, perhaps, it's okay on the railway, but if you have to walk on land, it's not possible, it's better to use this kind of temporary device, it's more troublesome, even if you get stuck on the road, you can unload things and transport them, right?

"Yang Daochang, look, is this for our Ministry of Industry?"

This official, his eyes are shining with golden light around this pole, it is too convenient, what a heavy thing, just so that three or five people can be hoisted, this, this!

"Okay, okay, since I took it out, I will give you the technology, and these technologies don't need to be kept secret, as for why they haven't been taken out before, you see this control, it's not simple, this needs someone to learn, otherwise, it's still very dangerous, you know, this hoisting is all heavy objects, one is not careful, that's a human life, and even, there may be several human lives."

Yes, it was Yang Qiao's previous life, a person who used this kind of simple pole pulling, if he was not careful, he would have an accident, let alone at this time!
