"Well, although the result is not good, but I like the process very much, what, talker, it feels contradictory, right?"

Listening to the information from all over the world, in fact, many of them were not sent by Yang Qiao's own personnel, but by friends, such as Li Er.

What did Li Er send, that is, this arquebus, there are several families making it, and even the enemy country has also made it, and among them, the enemy country is the most powerless.

There is also information sent by Cheng Fairy, that is, his little pistol has been almost stolen many times, that is to say, his small pistol has been remembered by others, and even, some of them are stolen, or their own good family, well, that theft is from the house, for this reason, he cleaned up the house once, but there are a lot of miscellaneous people who have been cleaned up.

"The predicate of destiny is sex, and the predicate of recklessness is the Tao, brother-in-law, how do you interpret this?"

On the side, Niu Baobao shook his head and carried Zhongyong on his back, looked at Yang Qiao in a daze, and asked by the way.

"Memorize it well, this is your teacher's homework for you, that is, to memorize the mean, and it doesn't let you understand the mean, and I'm just teaching you calligraphy, no other task."

Niu Baobao is not small, but, at this time, her study plan is to continue to memorize some classics, not to solve the classics, that is to say, at this time, it is a shaking head reciting, reciting, and reciting again, fortunately, in the middle, there is also a writing class, otherwise, the baby will be stupid.

Well, this is also a way of teaching, that is, at the beginning, the baby is small, so he can only memorize it, and slowly memorize it, and then, when he reaches the age, he starts to interpret the book, that's it, this, Yang Qiao can't say that it's good or bad, he has his teachings, and others have other people's teachings, however, in Yang Qiao's here, these predecessors' classics, but they can only be learned at a good age, except for those who are really interested.

"Princess, recite the mean well!"

At this time, this female official is also very powerful, is she supervising the recitation of Niu Baobao, at this time, you have to listen to her.

"Lang Jun?"

At this time, a secretary walked in with a craftsman carrying a wire roller, and this craftsman was carrying a basket.

"What is this?"

Yang Qiao was suddenly shocked in his heart, they, this is a breakthrough, this group, Yang Qiao has been putting pressure on them, but he has not given them any hints, but now, is there really a breakthrough?

This group, the so-called communication research group, has always been, they are the most stressful group of all the groups, well, Yang Qiao means that it is urgently needed, but it does not provide information, and there is not even a hint, ah, no, the simple two bamboo tubes and a thread have been prompted.

"Ding!"

Well, the technology tree in my mind is lit up again, this is independent research and development?

"Lang Jun, the communication team has made a new discovery, tell me for yourself!"

"Okay, Lang Jun, you see, we found that this carbon particle is pressurized, for example, if I talk to me, this current will be different, and then, this coil will add iron sheet, if this iron sheet must be thin, it will make a sound when adding current!"

Well, it's done, basically according to the normal way of thinking, but it's developed on the basis of the ammeter and voltmeter, and it's also considered to have an instrument, but this time, the amount, don't care, since it's developed, then, it's not going to be investigated.

"Principle, I don't care about it, that, when the time comes, you can look at your thinking materials, drawings or something, that, there are standard records, right?"

"Yes, Lang Jun, all records, even all ideas, whether reasonable or unreasonable, have been recorded, and even, even some useless words have been recorded, as long as there is a meeting, or someone suddenly remembers something, there are records, then, Lang Jun, we have shown it."

"You, you're alone?"

"Lang Jun, there are still a few people outside, I called them over, but doesn't it affect the princess's studies?"

"Princess, baby cow, since you want to see it, come and see it, soon, if it is successful, it will be installed by the father, and you can also talk to the father and the queen mother directly."

At this time, in fact, Niu Baobao has already memorized all the mean, and the teacher still has more time to give, and Yang Qiao will not add drama, so let's take a look.

"Hee-hee, brother-in-law, what is this thing?"

Niu Baobao grinned and lay on Yang Qiao's shoulder and watched these people at work, and saw that this person put down the back basket first, and a few people came in with outside, well, everything was in the back basket, originally they thought they were going to show Yang Qiao alone.

This is, hand-cranked generator.

First, he took out a set of shelves, and then, fixed a square object with a crank handle, and then, with his feet on the shelf, sat on the ground, and shook it with both hands, and on the side was a small electric bead, well, a small electric lamp lit up, and with the speed of shaking, it flashed and flashed.

Wiring, then, continuing to shake, the other person picked up a headphone, well, it was naturally the headset that was placed on the ear.

"Lingling, Lingling!"

Immediately after, a bell rang.

"Lang Jun, I heard it, I heard it."

"Experimental group, experimental group, did you hear it, did you hear it......"

Yang Qiao took the earphones and buckled them to his ears, the sound was too small to be tightened.

"Brother-in-law, listen to the Lun family, listen to the Lun family!"

"Listen, you go on, you should be able to talk to each other here, right?"

"Well, we're going to wait for the other party to send a signal, so let's stop generating electricity!"

So, the craftsman who was shaking the power stopped and the sound of the headphones naturally disappeared.

"Brother-in-law, it's gone!"

It's not that the brother-in-law is gone, it's that the other party doesn't speak.

"It's coming, it's coming!"

At this time, this little electric bead began to shine again, is this the other party shaking the generator?

"Send a signal, quickly."

Well, the other crank also shook up, this is a small signal transmission device, or a high-frequency transmission device, the other party should be ringing, well, how did Yang Qiao know, naturally, there is a manual in his hand No.

"Wait, hear, hear, wait, wait, wait......"

A microphone, a headphone, at this time, the headset also came from the voice of his own voice.

"Hey, brother-in-law, there's a voice again, there's a voice again, it's what he said."

"How far?"

"Hui Langjun, this line is three hundred meters long."

"Well, I'll give you a suggestion, if there is less dry battery, then, just use this generator to rectify it, rectification, you have all studied it, or rather, directly add a safe external DC power supply, so that when the other party is given a signal, after connecting, there is no need for one party to shake the handle all the time, and two machines are also needed, but, for the time being, let's do it first, more troublesome, more people, you are going to continue research, and also, the signal is a little weak, the sound is a little small, the next step, first look at ten miles, Then look at Baili. ”

Well, although this communication stumbled, Yang Qiao didn't give advice, in other words, if Yang Qiao gave advice, this phone call would soon be created, but Yang Qiao was so tough, he just didn't give them advice, or forced them to study it all the time, but he still gave them the goal they needed to achieve, that is, how to talk.

No, this person just needs to be forced, this is urgent, and it has really been studied, in fact, this thing is also simple, otherwise, where is it so easy, you let them make a nuclear pop-up now, well, Yang Qiao himself doesn't know, forcing others to do it, isn't that a joke.

And this phone, in fact, it's not that Yang Qiao didn't prompt, the front, the signal system used on the railway, isn't it a prompt, although it uses a lamp to make a signal, and the generator, it is also a prompt, and there is a voltmeter, an ammeter, this is all there, if it can't be tested, it's too stupid.

"Lang Jun, just this one line, all the communication?"

"You, hey, the railway signal, why a lot of lines, have you studied it?"

"I've studied, a signal light, a line, but this, you can say, you can listen to it?"

"Hey, you guys, what's the difference between this and a signal, it's just that there is one more listening voice and transmitting the sound."
