"Okay, boy, don't send it, it's my guard outside, but remember, in the future, if there is anything good, you have to think about me, otherwise, I will be unhappy."

Li Er smiled and threatened Yang Qiao, obviously, his psychological burden had been completely put down, since he couldn't do anything to Yang Qiao, then, just stay good.

"Girl, my father didn't give you the title of princess, are you not satisfied?"

The eldest grandson pinched Li Er on the side, and Li Er said this, he didn't know, Yang Qiao could see it clearly.

"Father, the daughter has not thought about it, you think too much."

The eldest grandson pinched Li Eryi again.

But Li Er was looking at Yang Qiao, obviously, he wanted to wait for Yang Qiao to say something, but unfortunately, Yang Qiao was not fooled, why did he want the title of princess, he had already discussed with Li Lian, if he had a daughter, it would be done, but what about her, he didn't want it.

Until Li Er went to meet with his guards, he didn't see Yang Qiao's reaction, he knew that tonight, one thing did not reach his goal, but this is fine, who can say whether this thing is good or bad!

It seems that Li Lian has the title of this princess, then, Li Lian is the eldest princess, this, no one can say the problem, then, Yang Qiao will have a fixed title of what kind of concubine is on his body, after all, he is an official, so the title of this princess is still not good, it is Li Lian, and she is also happy, this is called being unemployed and light.

The next day, in this imperial city, there is an idle courtyard, and soon construction will begin, this is Yang Qiao and Li Er discussed, this Chang'an City's power plant, located in the imperial city, at this time, Yang Qiao can not care about pollution or not, even, even Li Er does not care, at this time, safety is the most important.

Moreover, Yang Qiao also set up a final line of defense for the walls of this imperial city, that is, the power grid defense line.

This is really a step into modernization.

Why is it the wall of the imperial city, not the wall of the palace city, the main thing is that this power plant is outside the palace city, inside the imperial city, so the defense is the entire imperial city.

Li Er is very resolute in doing things, since he wants to do it, he will do the best, no, in this Chang'an City, black telephone poles have been erected, but why are they wooden telephone poles instead of cement telephone poles?

Well, it's not exactly a wooden pole, there are still some elevated iron poles, which are used to cross the city wall, which is for the wires, it is impossible to break the city wall, so the wires must be elevated, which is why there is a wire tower made of angle iron, and Yang Qiao feels that this wire tower, in addition to the steel number of this steel, is not necessarily worse than that of later generations.

As for this wire, it is not pure iron, nor aluminum, although Yang Qiao feels very capable, but, this aluminum, he does not have the ability to manufacture it now, here, but to use electricity, chemical combination, it is still quite complicated, to say, Yang Qiao himself made it alone, it is also possible, but can the things in this laboratory be produced in batches, so he just gave the craftsmen a research task, and did not say that he made it himself.

Earlier, I haven't answered the question of this wooden pole, what time is this, winter, so, it is wooden, not a cement pole, obviously, this wooden one, much shorter, however, short has the advantage of being short.

In Li Er's words, this tree is a good thing to prevent snitches! Also, you chased those spies who were not your own, and jumped on this wire, well, you don't need Yang Qiao to explain.

You know, although there is no high voltage, but because the iron wire has been processed, the resistance is still relatively large, so naturally, this ordinary civilian high voltage, ten thousand volt high voltage, there are still some, otherwise, on these poles, how can it be a double-layer wire!

Moreover, this transformer, but a transformer in a square city, no way, some large households, the use of electricity is terrible, however, some of the big households who are familiar with Yang Qiao, and Li Er also allows, that have their own separate power plants, just right, Yang Qiao's craftsmen can make a few more artificial steam power engines and generators, which can not only be proficient in technology, but also allow these craftsmen to really understand the working principle of this steam power engine, that is, to understand the principle of power, not the principle of power generation, at this time, Yang Qiao still scratched his head, where did he go to the workshop every time.

"Lang Jun, what is the principle of this generator, and this, why can it be used to generate electricity when it is shaken, and this, this, why is it just a combination of lead and zinc sheets, plus what kind of acid, it can also generate electricity, this power generation can generate electricity, how can there be a DC AC difference, and this, why these two pieces are inserted in this fruit, and they can also emit a weak current."

That's a hundred thousand whys.

"And this, this ore, why can it be turned into direct current when it is placed on an alternating current circuit?"

Oh my mother, you can't understand step by step, and blame me, why are you giving you these tasks?

What does this direct current mean?

What does it mean, this carbon brush, and the copper head, after many tests, the insulation between the copper sheets of the copper head is not up to standard, that is to say, the glue is not up to standard, so this DC generator, has not been successfully developed, so Yang Qiao had to take out the ore rectification first, because, the reason for using batteries, especially this battery, needs to be charged, this is not, it must be used DC.

These things are more troublesome to say, in fact, Yang Qiao is still very relaxed, what things, as long as they are arranged, they will become, as for the problem, there are naturally craftsmen who are responsible for answering the questions, and these craftsmen really can't solve them, so they will use Yang Qiao.

However, can there be a craftsman who can't solve this ordinary lighting circuit, ah no, in the future, this craftsman will not be called a craftsman, but an electrician, this electrician chief engineer.

By the way, the craftsmen who came out of Yang Qiao's family, at this time, are all called the chief engineer, not the chief engineer, only the chief engineer leads out, called a certain worker, finally, let Yang Qiao think of a standard name for his own craftsman.

That is, senior engineer, senior engineer, chief engineer, chief engineer, a certain worker, a certain surname, such as Li Wang Yang or something, is Engineer Li, Engineer Yang, and then senior technician, technician, technician, this is the Yang family's name for craftsmen, and these six levels are the titles of skilled workers from level four to level nine, the highest, that is, level nine, senior engineer, naturally, this is different from Yang Qiao's previous life, this level nine is also the technician level.

The first-level to third-level workers are ordinary workers, however, the first level is not the lowest, the lowest is the apprentice, when the apprentice, they are called workers, or craftsmen, because the workers of the Yang family are not workers, they are mainly based on research and manufacturing, so the classification of this level is only designed by the Yang family.

"Shengshang, the level setting of this Yang family's craftsman is very valuable for reference, I don't know?"

Naturally, Yang Qiao set it up like this, and there are some places where the craftsmen of the Yang family participated, this title has changed, naturally, it is also known, obviously, this title feels very chic, and it is also very clear.

For example, "Xiao Yang, bring me pliers?" ”

"Yes, Chief Engineer."

This chief engineer is also the only chief engineer of the Yang family, and there are not even many engineers, and most of them are senior technicians.

It's this senior technician, the title is more troublesome, for example, Yang Senior Technician, yes, call it so, just call it that, in the end, there is a difference, it's not a technician or something before, and at this time, the title of this technician has been reduced.

"How do you think this can be learned?"

Li Er is also very interested.

"Shengshang, the minister thinks, this, can not be all moved, moreover, this classification, a little too big, so, the minister thinks, we should be so divided, engineers, technicians, technicians, workers these four levels, each level, and then a small classification, and, some officials in charge of technology, should give them engineers to the level of senior engineers, this is also a new thing in our Datang, before, there were only some painters, bridge construction and other craftsmen, at that time, this technician was relatively few, so, how to call it all, Now there are more, naturally, to be subdivided, and these engineers and technicians are still very important. ”

Yes, as long as the discerning person can see that this technical personnel are very important, but not before, only the personnel with high command ability with high force value are important.
