The school is slowly getting on the right track, and Yang Qiao almost no longer gives ideas to his brother-in-law.

"Boy, why don't you teach more than calligraphy?"

Now, Li Er has a new habit, if there is something he doesn't understand, he directly summons Yang Qiao to ask, no, he has an idea again.

"I'm very busy, but maybe only I can teach this regular script."

This, Yang Qiao is not bragging, a, the regular script of the brush, he teaches the standard way of writing, which is naturally the standard writing method that later generations have only after thousands of exercises, although it may not be able to train any calligraphers, but, this is always a standard.

There is also hard pen calligraphy, this, no one teaches it, at this time, there are many people who are also groping for it, so Yang Qiao took the initiative to take over this task.

"Well, this is also true, although what you write is not necessarily the best, but what you write is the most standard, and it is the best for teaching, however, I have an idea, that is, the military school, should it be prepared, look, the battle ahead should be over earlier."

"Isn't it too early to finish?"

"I'm going to end it first, and really stabilize the land on this side of the river, and on the other side of the river, let's talk about it when I have time."

"Holy Lord, I'll give you an idea."

Since Li Er didn't want to fight, Yang Qiao suddenly had an idea.

"Idea?"

"Well, isn't there Goguryeo, Baekje, and Silla in front, and besides, they all have a feud, or they secretly arrange a part of the merchants to support one side and provide some weapons to the other party, and whoever is weak will support the bigger ones, and whoever is strong will support the poorer, so that they will always be at war, war, or war, and even, if they have any capable characters, just."

Yang Qiao gestured towards his neck.

"Ha, you kid, good or bad, good or bad, but, I like it, so I will do it, then, I will arrange to withdraw from the army, but I can't retreat back a year ago, so I must first stabilize the territory that has been defeated."

This is the sadness of the lack of people, it's not that Li Er doesn't want to expand the territory, but that no one uses it, he has the heart, but he doesn't have the strength, otherwise, he wouldn't have been beaten back by Silla in the later period of the empress, and what Goguryeo and Baekje were beaten down by Li Zhi in the later empress period.

It is because of this historical record that Yang Qiao is still very willing to let Li Er really stabilize the territory he has beaten first, and then what Khitan and Turkic are attached to it, which also needs Li Er to govern, otherwise, when you are weak in the Tang Dynasty, these people will bite you in turn, so this also needs to be governed by Li Erxian.

"This matter in front of us is settled, but, this matter of the military academy?"

"Well, this, Shengshang, I don't think there is a need to be too anxious, the military academy can be merged with the previous training camp, and the territory of the training camp in the city can be changed into a military school, but it is best to find a place in the imperial city first, as a school directly under the Holy Shang, called the Senior General Refresher Course, that is to say, let the generals who can be called generals in the Tang Dynasty take turns to enter the class to train new combat knowledge and new weapon use."

"Boy, hey, when did that kid leave?"

This Li Er, just thinking about that beautiful thing, actually forgot Yang Qiao's departure, you know, this time, when Yang Qiao entered the palace, he actually forgot the most important thing, that is, this military academy wants Yang Qiao to preside, but, looking at this meaning, Yang Qiao obviously doesn't want to preside.

Also, there are already some things that are not in the front, what should be taught, and what should not be taught, Yang Qiao really doesn't want to participate, and Yang Qiao can still see Li Er's helpless eyes on Yang Qiao, so staying away from danger is what he wants to do most now.

………………

"Lang Jun, we just wanted to arrange someone to call you, but we didn't expect you to come now."

This, in fact, Yang Qiao also knows in his heart, the speed of the craftsman's work, as well as the amount of labor, allows him to grasp the progress of this project, no, as soon as the prototype of this generator comes out, Yang Qiao also arrives.

"You've tried it, haven't you?"

"Lang Jun, not yet, no, I'm preparing to test it, this connection, we use a belt, not a direct connection as you said."

Also, this direct connection, Yang Qiao took it for granted, maybe, he didn't think much about it at the beginning, but these craftsmen are different, they can find that this direct connection, they have not been able to do it recently, maybe, some designs are there, but, this technology, it seems that it can't be reached, maybe, there is still a layer of window paper in it, just waiting for someone to poke it.

"That's fine, it's good to use the split type, direct connection, you don't need it, and the speed and even the frequency also need to be adjusted, so that the split type is even more needed, and there is an indirect connection."

"Huh?"

When he saw the generator, Yang Qiao's eyes suddenly lit up, originally, he thought that this generator would be caused by a black iron bump, but in front of him, is this a machine, or a work of art?

Look at this shell, it should have been carefully polished by them, and it also had a layer of varnish, which looked oily, and those places with heat vents were covered with delicate copper wire mesh, these craftsmen are really a waste, this copper, but it's money!

A generator for such a work of art, I just don't know if it can generate electricity.

"Lang Jun, you see, this is a carbon brush, which is made of toner powder, and a carbon brush made of glue extracted from pine resin, for the conductivity you said, it is also mixed with some very fine copper powder that you requested, and this is what it looks like, and the wire that comes out of this is also a wire woven with copper wire that is thinner than a hair, and these connecting pieces are also made of copper."

The craftsman explained in detail every part of the generator he made.

There is also the problem of soldering that you mentioned, that is, according to your requirements, we used most of the tin and a small amount of lead to synthesize the tin bar you said.

If you want to use electricity, this soldering technology is indispensable, it is said that it will be better to use copper for direct welding, but at this time, Yang Qiao does not have the ability to manufacture convenient brazing equipment, so it is still the most commonly used soldering, and this soldering should be enough, as long as it does not require strength for welding, and there is an overheated place.

"So, what about rosin, have you tried it, can you weld?"

"Well, yes, yes, yes, Lang Jun, you see, this is copper and iron, soldered together, that is, this is not too strong, as long as you twist hard, the copper on this soldering will fall off, but this soldering, used to repair copper, is a good thing!"

Well, let these coppersmiths discover a new technology for repairing copperware, these big families have a lot of copperware, but there is also wear and tear, even if it is a large household, throw it, don't give it, don't throw it, can't use it, you have to repair it, and, how to repair it before, with riveting, this technology, is terrible.

And now, they have discovered the technology of soldering, not that they didn't know how to use it before, but there is no flux, that is, rosin, who knows, this pine oil can make this copper and other gold, silver and iron welded together, and then make jewelry, it seems, there are some special types, can also be done.

"Lang Jun, you see, this is the new jewelry they made, and there are some copperware, tin ware, etc., all of which use tin soldering technology, and this is a soldering iron, and they also make many kinds of shapes, all of which are made of copper welding heads."

What is this introducing, how to digress, this actually looks like jewelry, but these jewelry, it really feels very beautiful.

Lang Jun, look at this butterfly, in the past, it would take more than a month to make it, but now, it can be made in three or five days, and it is more beautiful than the one, and there is also this connected place, which can be made more exquisitely.

"Okay, okay, don't talk about these jewelry, perhaps, arrange two craftsmen to go to my eldest sister, teach her craftsmen, and let her open a jewelry shop too."

With this new technology, Yang Qiao's first thought was to launch it.

"Okay, Lang Jun, then, let's continue to introduce this generator."
