Chapter 26: Eve

Chapter 26 The Eve

That night, Bai Yang lay in bed and couldn't sleep.

He has always been unable to sleep at night these days.

Today is September 29. Tomorrow is the last working day before the National Day holiday. The holiday will begin the day after tomorrow. Even though they are senior high school students, the Education Bureau has given them a full seven-day holiday and strictly forbidden to make up classes.

There is no moon tonight, no clear weather after rainy days, the external unit of the air conditioner hung outside the wall is "buzzing", the indoor temperature is set to 25 degrees Celsius, although it is not hot, but boring, it may be that the doors and windows have been closed for too long. As the carbon dioxide concentration rose, Bai Yang took a deep breath and put his hand on his forehead.

He was wearing a white short-sleeved t-shirt, **** shorts, one leg bent, and his body was paralyzed on the bed motionless, but his thoughts were in his mind.

When the tritium tube arrives tomorrow, he can start to make the time marker by hand, then put it into the time capsule and bury it in the lawn by the square of the community.

Where should I bury it?

Bai Yang outlines the floor plan of the plaza of the Meihua Villa community in front of her eyes.

The square is the boss.

The time capsule is such a small thing as 20 centimeters long. If you can find a place to bury it, you have to plow the ground with a tiller.

It would be easy if she had a metal detector-just like the mine detector used by the Japanese Devil Engineers to deal with landmines in the war landmine war, it swept the ground like a lawnmower, and when it found a landmine, it shook the ground. Its principle is simple electromagnetic induction. As long as the girl carries a metal detector in her hand and sweeps around the lawn, she can find her buried time capsule.

Of course, unexploded mortar shells may also be dug.

So there must be a marker.

Buried behind a bench?

Or buried under a tree?

Poplar contemplated, there is no doubt that the markers are very important, but he should not bury the time capsule in a place that is too conspicuous and easy to be found. After all, the thing must be safely hidden for twenty years.

If you hide in a place that is too easy to be found, then you can’t say one day in the future that you will be killed by a certain Cheng Yaojin halfway.

The cataclysm of the destruction of human civilization, the world will become so chaotic that Bai Yang simply can't imagine it.

He decided to step on a spot on the ground during the day tomorrow and find a few alternative locations. This location must meet the following conditions:

First, concealment.

Undetectable for as long as twenty years.

Second, safety.

cannot be lost or destroyed in a disaster.

Third, make sure the other party can find it.

So there must be an accurate coordinate, even in the past two decades, the other party can find the buried location based on the coordinate.

When she buried the time capsule, she told BG4MSR the location and asked her to dig it out.

White Yang took a long breath.

This is really interesting.

Do the electromagnetic waves radiated by the radio really have the ability to travel through time? 14.255M Hz shortwave emitted by ICOM725 shortwave radio-light is also an electromagnetic wave, can light span time?

Light may have the ability to span time. On any starry night, open your eyes and look up to the sky. The entire starry sky you see is very old.

To you, they are the past, to them, you are the future.

But can you talk to them in real time?

Can the future and the past be able to talk in real time?

The physics teacher hammered the board in the coffin: Impossible! The speed of information transmission cannot exceed the speed of light!

Bai Yang turned over on the physics teacher's coffin board, turned sideways, and looked at the old black Icom 725 on the bookshelf. Others always said it was a radio. In fact, its structure is not much more complicated than that of a radio— —The core of the radio station is just a set of simple LC oscillator circuits, and the basic composition of the LC oscillator circuit is just an inductor and a capacitor. The inductor can be bought on Taobao for two dollars, and the capacitor can be bought for two dollars. A large number of these two things together can produce high-frequency oscillating current, and a radio station like 725 that uses a quartz crystal oscillator is more trouble-free. The crystal can vibrate when the crystal is energized, just like He Leqin who stepped on the switch, only He Leqin for one second Shake several times, the crystal oscillator shakes millions of times per second, and the high-frequency oscillation signal that is shaken out is then transmitted through the power amplifier and antenna. This is the principle of the radio station transmitter... With such a simple structure, it can travel through time. It is better to say that a spaceship can be built out of planks and nails.

There are so many things in this world that look mysterious and mysterious. As long as you uncover their shells, you will find that they are just grass-roots teams.

Bai Yang turned over again, and lay on his back looking at the ceiling.

The light in the room is very dark, and the white roof of the bedroom can’t diffuse enough light to enter Bai Yang’s eyes, so Bai Yang doesn’t think it’s white, but it’s not black, just like what you see when you close your eyes. , You can hardly say that it is a certain color, it is fuzzy, dim, as if beating the noise of an old black and white TV.

Bai Yang took out the phone from under the pillow and turned on the flashlight to the ceiling.

The bedroom suddenly lit up, and there was a huge white spot on the ceiling. At this time, the path of the light was clear and followable. Bai Yang thought of the electromagnetic wave propagation path of the radio station. The radio wave radiated from the antenna of the radio station and went up dozens of kilometers. When it touches the ionosphere, it is reflected down again-just like the flashlight in Bai Yang's hand at this moment, the light is emitted from the LED, touches the roof upward, and then is reflected into a pair of opened eyes-

The girl blinked.

Banxia lay on her back on the bed, staring at the white light spot on the ceiling.

She shook the small desk lamp in her hand, and the light spot on the ceiling also shook. This game is quite boring to be honest. She is not a cat and is not interested in the dangling light spots.

But she has nothing else to do.

Can't sleep at night.

Banxia turned over and lay on the bed. She was wearing a white vest and black pajamas on her lower body. She hugged the pillow and buried her face in her arms. Then her two lower legs raised up and patted the bed board. , "Bang Bang".

After taking a few minutes, she didn't move anymore, lying straight on the bed, her face stuffed in the pillow, like a corpse.

So annoying.

Tomorrow-at most the day after tomorrow, BG4MXH will tell itself where to dig treasures.

Can this plan really succeed?

So annoying, so annoying, so annoying, so annoying.

If you can’t succeed, just take the other item!

snort!

Banxia raised her hand and swiped into the void.

No, he is the only one who knows me, where can I find the next one?

So Banxia stretched out her hands and put her head back into the void.

If it is really the menstrual period, I usually don’t feel so anxious. Pinellia raised her face, sighed, spit out the hair in her mouth, turned over and lay on her back on the bed, holding the lamp on top Hands.

She regularly presses the lamp switch in her hand to make the light flash.

Teacher taught Pinellia how to send CW equal-width reports, which is Morse code, but Pinellia is not very proficient because it rarely comes in handy.

Long and short, click and click.

"G."

Banxia reads silently in her heart.

Long and long, click and click.

Length and short, tap didi.

"Next is..."

Short long short, short short long, long short long short, long short long.

LUCK.

"Goodluck."

Short and short, short and long, short and long and short, short and long and short, long and short and long.

"HAPPY."

Pinellia uses fingers to draw two short arcs in the dark, and then draw a long arc to form a small smiling face.
