"Boy, today, I came to you for two important things."

When Yang Qiao came to the palace, Li Er said to Yang Qiao very seriously, all along, Li Er had never used the word "I" in front of Yang Qiao, but this time, it seemed too formal.

"Holy Lord, you say."

Yang Qiao also sat on the side with a rare seriousness, listening to Li Er's words.

In particular, the eldest grandson hid behind the curtain, although she could listen, but she did not participate.

"Boy, one is, recently, the horse-drawn train, there have been several accidents, do you know, among them, three horses died, and five horses were seriously injured, which is no longer useful, and a few horses were slightly injured, this, can be treated and then transferred to civilian use."

Accident, Yang Qiao's heart tightened, he was afraid of this kind of thing, so, all along, he has been very strict with the training of personnel on this railway, but he didn't care about it for a while, and there was an accident.

"So, what about the personnel?"

"The personnel are fine, because you used a new iron chassis, so, only the horses were injured, and the people were just a little frightened."

"Ah, that's good, that's good, it's good that there are no casualties in this person, Holy Lord, I'm not saying, who is in charge of this part, and dares to violate my regulations, otherwise, how could there be an accident, this is to say that the train, this accident, it's a big deal."

"The train, not nothing, but almost, thanks to the whistle you added recently, so that the horse-drawn train can be heard from a long distance, and the driver and crew also reacted quickly, when they heard the whistle, they quickly took the horse to the back, and went back, just a little bit!"

Speaking of this accident, Li Er was a little lucky.

"Holy Lord, what about this, I don't actually have any good ideas, even if there is, people are careless, I have no choice, the only thing is to carry out a disciplinary rectification of these personnel, and even fine, you know, their salaries are quite a lot."

At the beginning, Yang Qiao thought of this aspect, so only if the salary is high, can he be heavily punished, isn't it, such a high salary, you don't do a good job for me, what else is there to say.

"Listen to you, these boys should also be educated and educated, then, the second thing is that the air bridge has had a lot of trouble recently."

"What's the trouble with the bridge?"

"It's not this train, it's a rare thing, so whether it's a nobleman, a royal family, or a commoner, they all want to go up and have a look, no, it's trouble."

"This is also a trouble, so I don't need to solve it!"

Li Er estimated that Yang Qiao would not give any solution.

"Then, that's it, let them think about it, after all, you can't make a fuss, isn't it just an observation deck!"

In fact, this is not a casual viewing platform, but has become a scenery of Chang'an City, if you install colored bulbs on it, it will look more beautiful, and it can also let ordinary people go up, and there is, this Chang'an City, outside the city, can be watched, perhaps, on this observation deck, there will be some poems that have been handed down to future generations!

Li Er's finding for Yang Qiao reminded Yang Qiao that this signal should be kept up with as soon as possible, this accident may not necessarily be man-made, it may also be when the manpower is exhausted, not to mention, because of fatigue, or for some reason, which led to the mistake of the signaling personnel, so it is the most important thing to reduce the burden of some important personnel as soon as possible.

And at this time, what was the craftsman in charge of studying the signal doing?

"Toot,"

A whistle sounded from the hill in the distance, and a man was waving a red flag.

"Toot toot."

Immediately afterward, he blew two whistles and raised a green flag in his hand.

"Toot toot."

And on the hill in the distance, two whistles also sounded, and there was a green flag.

If you want to talk about this signal, naturally, it is not about the whistle and the flag, but also the bells, lights, and special vibration bells.

In other words, the simplest signal has been successfully studied, Yang Qiao doesn't need to ask, just look at their happy looks, just know, and a few days ago, when he came, although it was also like this, but the people who watched this experiment were frustrated.

"Lang Jun!"

Sure enough, when Yang Qiao approached, the craftsman greeted Yang Qiao excitedly.

"What, the experiment was successful?"

"Well, I can't say yet, but I think it should be successful, and the response signals given by the other side are all qualified, so I'm waiting for the person on the other side to come back and report again."

"By the way, I asked you to test it with wire, did you do that?"

"Yes, Lang Jun, you see, no, for this reason, we have also specially erected a telephone pole, which is carbonized according to your requirements, after testing, the telephone pole treated in this way should not rot for a hundred years, and the iron wire on this is also newly made by the blacksmith shop of the imperial court, and this porcelain pot is also made by the porcelain workshop of the imperial court, but why can we make these things, and let the imperial court make them?"

Why, naturally, these things are not a big deal technology, so Yang Qiao doesn't need to arrange craftsmen to make them by himself.

"Big brother, big brother, good news, we have passed those steps of yours very clearly, this is a record, ah, Lang Jun is good!"

"Well, you guys do yours, I'll just watch it."

Yang Qiao waved his hand, watching them do all kinds of tests, and didn't want to interfere with them themselves, although the tests they did were different from the tests in Yang Qiao's mind, but they had the same goal, as long as they could play an effective role, and this was their own thing, so Yang Qiao still supported them.

"Okay, the remote test is over, now, let's conduct a two-way test, so that you go to the room over there, and I'm still in this place, this time, we don't need a whistle, and a flag, just a bell, and a signal light to do the test."

"Okay big brother, Lang Jun, then, I'll go."

"Go ahead!"

Yang Qiao waved his hand, but looked at the craftsman.

"Lang Jun, this so-called two-way is this iron line, which leads to the mountain over there, and then lets the mountain over there transmit it to the room over there, which is the two-way journey, that is, two signals."

This craftsman understands well, as long as this so-called two-way test is successful, then, that is, this is already a signal of interconnection between the three stations, this is already considered a success.

"Bell bell bell ......"

It's a long tone.

"Lang Jun, this signal is to remind the other party of the station, and a signal has been sent to the other party."

"Lingling."

It was another bell, only two, and with that, there was a green light on.

"Lang Jun, this is a signal to the other party."

"Bell bell bell ......"

"Lang Jun, this is a signal from the other party to return, proving that it has been received."

"Bell bell bell ......"

Then, in the room over there, there was also this bell, and here, there was nothing.

"Lang Jun, this is the other party sending a signal to a third party."

With the explanation of the craftsman, one step after another, I went through it.

"Well, that's good, but, this time, let's see and give a different solution, don't mess up."

Soon, Yang Qiao saw some unsatisfactory places and pointed them out one by one.

"Also, after a while, I will arrange for you to go to the railway to impart this knowledge, and also, what telephone poles, wires, porcelain pots, and all kinds of electric bells and other accessories, all arrange people to do it, and we will not be responsible for making these things."

This is a supplier's business, which can make money, but Yang Qiao doesn't have the energy to do any business, naturally, he has to sell, as for who sells and who buys, it has nothing to do with Yang Qiao, he just collects money.

"Boy, this time, why didn't you give it away for nothing?"

"Give it away for nothing, it depends on what it is, you know, these things, that is, Li Er, will not be arranged to be made in the workshop of the imperial court, naturally, you can't cheap the other party, you have to collect money, besides, this is a special supply of goods, and I am not afraid of who steals the technology."
