In the training of secret guards and secret agents, perhaps, Yang Qiao has some less experience than others, but Yang Qiao will have more advanced knowledge than them, at least, in terms of clothes, Yang Qiao is more prepared than them, and it is more advanced, this is the production method of camouflage uniforms.

"Husband, you said that this dress has always been black, isn't it stupid?"

"Maybe they have a traditional special training method, and our family, the accumulation is insufficient, so, there are no such things, so I can only change, that is, the color of the clothes is more style, and even, there is a style of discoloration, you see, the dark guard squatting in the corner, this clothes, is the color you saw when you first came out, and now, it has changed color, however, this kind of fabric, but the most expensive fabric, will not be sold to the outside world, at most, add a part of the family's clothes, uh, It's still under development, let's see, add a good look to someone's clothes. ”

This fabric, using special silk, and pigments, is mainly based on some principles of light refraction, uh, this, to tell you, you don't seem to understand, you just need to know, this dark guard's clothes, the most expensive become, but at night, it is also black, well, the moonlight is the brightest night is different.

"At night, they will also be on duty, then, they will not rest"

"Rest, or, why are there two of them, after all, they have to be given time to eat and rest every day, and that is to take turns."

"Okay, let's not introduce their equipment, let me tell you how you manage them, what about you, don't talk to them, even talk, but also talk about some useless, such as, the price of vegetables, whose calf is sick, whose mother-in-law broke her daughter-in-law or something, you just can't talk about yourself, you can't talk about the secret guard, you can't talk about things related to these things, don't be heard by others to go to any secrets, and this secret guard can only be commanded by you, oh, and, the one who called out their code name can command one to emergency."

"They're already here, let's talk about something else."

"Well, these two fools, in the future, when I want to say something important, I have to look around first."

"Look, it's normal, but it's not possible to keep it secret, unless it's in the room, in the future, our room, will be on the ceiling in the room, even if it's not the ceiling, then, but also under the tile on a layer of boards, I see who can also lift the roof tiles, you can hear the words below, or, just replace the small tiles with large tiles, the wooden planks, to replace the reed boards, but in this case, you still need the ceiling, the ceiling of special design, and, but also with wooden boards, patterns, elements lightIn this way, as long as there is a mosquito on it, it can be seen clearly, and if there is a small hole for eavesdropping, it can also be heard clearly. ”

This, can be explained, this opening of the tiles to eavesdrop, is only these old small tiled houses, in Yang Qiao's previous life, the tiles in some places have been replaced by large tiles, in fact, it is not appropriate to have this statement again.

Small tiles, that is a purlin, the purlin is a wooden plank on the top, and then, on the top is a tile, so that when you lift the tiles, you can see the things in the room below, if the grass house, uh, don't think about it, but, the grass house, who will eavesdrop, but, the grass house, it is also easy to eavesdrop, on the side of it, and use the roof.

There is also the poke window paper, which is coaxing the two fools, the window paper pasted inside, you poke it open, as long as it is talking about the secret, you will not look at the window paper at any time, such a big eye, you can't see it, uh, don't say it, it seems, in the story, if you don't poke the window paper, it won't become a secret of eavesdropping.

In fact, in the Yang family, this roof tile, basically there is no more, mainly there is a ceiling inside, this ceiling, one is, it can prevent rain leakage, well, when the rain leaks, you can flow the rainwater down the ceiling to the wall, instead of coming down directly from above, once the rain leaks, below, such a basin, such a basin, even sleeping, can't sleep, but, with the ceiling, uh, this rain leakage, it is easy to solve.

But, again, eavesdropping is also avoided.

And the window paper is a better solution, the Yang family, basically all the glass windows have been replaced, you can peek, but you can't eavesdrop, it's magical, you can't poke the window.

"Also, it's lip reading, but this ability, not many people will know it, as long as it's not too important, you don't need to avoid this ability."

"Husband, this lip reading is"

Reading her lips, Yang Qiao seemed to have said it a few times, and the Seventh Lady couldn't help but ask.

"Just by looking at your lips, you can know what you're talking about, but when there's really no way to avoid it, you can learn ventriloquism, and after all, there are many ways to avoid leaks."

At this time, Yang Qiao was explaining to Xiao Qi some ways to eavesdrop, peek, and even lip reading and other leaks, as well as the way those spies acted, and forgot about the business.

"Husband, that's all for this, you better put me down, weird tired, I mean I'm tired, this posture."

"Okay, you learn these first, and I'll explain some to you later, you see, here, we build a courtyard where the main family lives, naturally, it is also a temporary place to live, most of the time, you still need to live at home, over there, it is the place where the people and the shopkeeper here."

Because of the air pollution problem in this city, so, here, I will arrange to plant some trees that are relatively thin in size and have relatively sparse branches and leaves, why should they be sparse, mainly to prevent outsiders from coming in, and there is one less place to hide, if the branches and leaves are too dense, this tree, you can hide a few people, but it is sparse, you don't need to look, naturally, there will be your secret guard to report to you, madam, people come in, on that tree.

Even, perhaps, you yourself will be able to see someone in a tree.

Troubles, Yang Qiao's own sin, that is this air pollution, well, in fact, the main thing is the pollution of this soot, and there is the pollution of the fire wall of the fire kang, it is too serious, don't say that this fire kang, the pollution of the fire wall is small, the main thing is that the people living in this city are rich people, and there are those who have no money, but they occupy a small area, which can be ignored, they only have much less coal every winter, and the chimney at home emits a little green smoke, even if it is good, but, what about the rich people, the coal, but a lot of burning, the room should be more than warm as spring, In particular, Yang Qiao also designed a room humidifier, that, this room, is going to be very hot, especially this dress, that is, when you enter the house, you can take off the cotton robe and leather clothes you are wearing, and only wear a single coat, naturally the room is going to be hot, and there are more rooms, this chimney, the black smoke every day, this adds up, and it will not even be less than the black smoke of the power plant.

However, this is also good, so that Li Er fully understands the horror of pollution, but Li Er has no choice, whether to demolish the fire wall, or dismantle the ondol, or dismantle the power plant

Nothing can be done, so, in this palace, there are now more trees, similar to Yang Qiao's requirements, to thin trees, almost every year to replace, not afraid of dense branches and leaves, what, trees can't support people, however, it is enough to remove dust, but, at the same time, it still increases the load of the power plant, which has trees, naturally, there are more lights, in order to eliminate the shadows, to avoid people inside.

"Husband, can't this pollution be avoided?"

"Avoid, it should be possible, one, you can relocate this power plant to the mountain, and then, this smoke and dust, can be eliminated by going down the ground, however, one needs money, one needs a good conduction line, you know, why this power plant is increasing with distance, the main problem is transmission, this wire, can not afford to consume, iron wire, transmission consumption is too large, copper wire, silver wire, copper consumption, silver consumption is too much, so, it is also a difficult thing, so, now there is an urgent need for new wires."

"Husband, that, our household wire"

"Some places use copper wire, some places use silver wire, you know, our family, the consumption of this wire, is really not small, so, this, our home, it seems that there is also a need for new wire."
