Someone once asked me, do you like summer or winter? If it's in the summer, I'll tell him I like winter, and when it's winter, I'll tell him I like summer.

In a summer when there was no air conditioning, no fans, and even no electricity, I once swore that I would rather freeze to death than die of heat.

However, no matter how hot it is, it can't kill me.

The mat is an artifact in the summer, the hard and smooth outer surface is always attached to people's hot buttocks, without any complaints, if you can give the mat a chance to say a word, then this sentence must be: hot me!

It's not enough to have a mat, you also need wind, it doesn't matter if it's cool or hot, there must be wind. The mat is easy to obtain, but the cool breeze is hard to have. The hot air is also a hot wind, and it is very uncomfortable to blow on people.

And all this has changed because of its appearance.

It was a sunny day, with a maximum temperature of 378 degrees, extremely dry, but fortunately there were a lot of clouds in the sky, at least not all the time in direct sunlight.

It just popped up.

A strangely shaped cloud in the distant sky caught my attention, like a big cotton ball, not floating serenely high in the air like other clouds, but tumbling as if something was about to burst out.

That's right, something really rushed out. However, I was stunned. It turned out to be a huge electric fan, to be precise, an electric fan with only a fan, and only a round frame covering the fan.

It was a huge silvery-white fan, measuring tens of thousands of meters in diameter just by visual inspection.

Just then, the fan moved! There is no power cord, I don't know what the power of rotation is, but it just moves.

People all over the world were amazed by the sight.

As soon as the huge fan in the sky turned, the surrounding clouds couldn't stop leaning over, and then it was as if a ten-level wind was blowing, which directly blew me on my head. I sat backwards on the ground and opened my mouth to form a huge circle.

Then, the sky changed. The gray clouds began to slowly gather around the huge fan, and behind the fan formed a vortex, like a huge horizontal funnel, which was a sight that was rarely seen before.

People came out of their homes and looked up at the sky. As for what is playing on the TV in the house, how can you come out in person to see it more clearly and realistically?

It's cloudy and windy, not to mention a big fan? The four wings of the fan slowly turned, and the dark clouds that had finally gathered were blown away! The big fan is facing east and west, and it has changed the weather forcefully, and the area of influence is tens of kilometers, basically covering the area of a province.

When the wind was up, the temperature dropped a lot, and I was very happy that I finally didn't have to turn on the fan. Judging from yesterday's weather forecast, today's maximum temperature will be 35 degrees, but now it is not that high.

Just when I had seen enough, three helicopters flew over. The fluttering sound was so loud that it overshadowed the sound of the big fan in the air. I'll take a look, hey, that's interesting, I'll look at it for a while!

The helicopter in the middle is obviously the most important one, only it is the closest, and the other two are circling the big fan, probably trying to find out the import and export of the big fan or something.

Could that be an alien spaceship?

I couldn't help but think about the three helicopters when they looked so serious.

I looked at the TV in the house and saw that the perspective had changed, to a close-up view of a helicopter. I quickly ran into the house and sat on the floor watching TV. The picture played in the TV is a large fan in the distance,There are some patterns similar to circuit boards on it,The color is similar to the silver-white of aluminum alloy,There are a few black lines in some places。 There was a helicopter that circled around the big fan, but it couldn't find anything like a window or a gate.

Could it be that the windows or doors above are also silvery-white? So you can't see it?

I thought with my chin crutched.

Without finding a window or door, the three helicopters prepared to retreat, unable to communicate with those inside.

Just as the three helicopters gathered together and stood in a row to leave, the fan made a whistle like a ship docking, and with the sound, the four wings slowly slowed down, and after a while, they stopped moving, and the position happened to be a standing cross. Then, the shell of the fan spews out a puff of white smoke in the four directions of the up, down, left, and right, and the bottom left moves a short distance to both sides, and then the bottom left slides up along the outer edge of the top left block to the top left, and the same goes for the bottom right. Then, the two pieces that moved up slowly straightened from a 45-degree arc to a horizontal direction, and were lifted up by the fan wings standing in the middle, which were about half the length of the fan wings. I was already confused, and I saw that the vertical fan below was divided into two identical parts in the east-west direction, forming an angle of 180 degrees, probably to maintain balance. At this time, the horizontal fan wing on the right quietly stretched out a large section to the right, the length of which was as long as a fan wing, and a small section stretched out at an oblique angle of 45 degrees can be seen at the far right end. It looks like there's a little fan spinning on it.

This...... Isn't that what a helicopter looks like?

I stared wide-eyed, shocked.

Everyone was shocked, and at the same time, they were all stunned.

The expressions of the people on the three helicopters, I can probably guess one, two, three, I guess it's all you look at me and I look at you, frowning, I don't know why.

Is this a parody mechanism?

So far, nothing has come close but the clouds have ever come close to the big fan, not even a bird.

Just when people saw that this was what a helicopter looked like, the wings of this huge "helicopter" turned up!

Well, it's more like a helicopter now.

No, it's just a look, it's not a real helicopter, and the most important thing is that it can stop in the air before it becomes a helicopter, and its wings are still spinning so slowly.

I looked at the "helicopter" moving slowly in the sky and wondered, what is this thing doing?

The "helicopter" lasted only about ten seconds before it stopped, and then, as if it were being played backwards, it began to slowly resume its fan-like shape.

The three real helicopters witnessed the whole process and suddenly felt very interesting, as if they were approaching a chameleon.

Some people didn't enjoy watching it and wanted to watch it again, so they ordered one of the helicopters to come forward again.

The helicopter was seen grabbing around the big fan, quietly waiting for a miracle to happen. However, after waiting for a long time, the big fan did not deform again.

Hey? How did it not change? Could it be that this transformation can only be changed once?

I have the same question, what if I get close with something else?

Sure enough, someone thought of it with me, and I saw a drone appear. The drone flew around the big fan and left. People have rekindled their inner expectations and want to see the big fan deform.

Sure enough, the big fan really began to deform, and it took less than a minute to turn into a huge "drone". The "drone" traveled around the sky for about ten seconds before stopping, and then it turned back into a big fan as expected.

Just as people were thinking about the next thing to get close to the big fan, a small bird suddenly appeared next to the big fan. The curious bird was curious, so it stopped in front of the big fan.

The one with the sharp eyes spotted the little bird and shouted, "Look! There's a bird there!

Sure enough, a bird appeared on the TV.

At this time, the big fan moved again. It began to deform with a few clicks, but instead of taking on the shape of a bird, as one might expect, it was in the shape of a giant funnel, like a radar. After that, people heard a tick-tick sound, as if it was some kind of signal.

Most people don't know what's going on, but those clever scientists have received a strange set of signals, and the content of the signal has not yet been cracked, but the source of the signal for a peak in two seconds is the radar at high altitude.

After a few minutes, two missiles flew from the sky.

Originally, I didn't know what this tick sound meant, but when I saw the missiles flying in the distance and the radar towards the higher sky, I had already guessed an approximate idea.

Just two missiles can destroy a big fan from afar?

I don't have much confidence in these two extremely fast missiles.

Sure enough, when the two missiles were still more than a thousand meters away from the big radar. On the edge of the radar, a columnar object slowly emerged, which was a replica missile. This "missile" fell like a ripe fall, and then flames erupted from its tail, flying towards two missiles more than 200 meters away not far away.

Can even missiles be copied? Well? It was not by explosion but by impact that the missile was destroyed?

I looked at the missile that had just been imitated and had shot down two missiles fired by humans in quick succession, and I thought about something.

Within ten seconds, a fighter plane appeared in the sky, and it turned out that it had launched the two missiles.

When the fighter was still a few kilometers away from the big radar, two more missiles were fired.

The big radar already has a cache for the missile, so the time taken to imitate a missile has been greatly reduced by nearly 96 percent compared with the previous one, and it can be said that it was imitated in an instant. With a whoosh, it not only shot down the two missiles that ushered in it, but also flew towards the fighter.

The nimble and fast fighter narrowly avoided missile collisions on several occasions, and the pilot received orders from his superior commander to use his machine gun to knock out the signal transmitter in the center of the radar.

The range of the fighter's machine gun is only a little more than a thousand meters, and it can only hit the target if it is close to the innermost part of the radar. The fighter's intentions had been learned by the radar, so he copied another missile, and at the same time the whole body was mobilized, and layers of circular steel plates appeared in front of the fighter's flight path, so that the fighter had to make the decision to change the direction of flight, or else it would collide.

Before changing the direction of the fighter's flight, the pilot tried to knock off the protective steel plate with a machine gun, but it was useless and could not be penetrated.

After the fighter attack was fruitless, they had to leave, mainly because there was not enough fuel.

The two replica missiles also flew back to the radar, and after returning to their positions, they became part of the radar again.

Humanity did not give up the attack, and after the withdrawal of the fighters, ten ultra-long-range self-propelled guns were sent. These 10 vehicles were parked in the woods more than 50 kilometers away from the high-altitude radar, and took advantage of the concealment of the trees to cover their whereabouts, preparing to deal a fatal blow to the radar, and all the guns were aimed at the signal emission source hanging high in the center of the radar.

The distance of 50 kilometers is far beyond the detection range of the radar that can scan objects and imitate them, and the shells fired by the howitzer fly extremely fast, even if it wants to block it, it will not have time to deploy.

Ten self-propelled guns opened fire in turn under the command of the Supreme Commander.

With a few clicks, ten shells flew into the sky in less than two seconds.

No matter how sluggish the radar's defenses are, they will react. The signal source at the center of the big radar fell with a whoosh and disappeared.

Ten shells flew over the large radar in an immutable course, and they didn't even touch a single hair of the radar, although the radar had no hair, but the meaning was that.

Just when ten self-propelled guns were preparing for the next attack, the radar had already detected it. It took less than two seconds for the radar to imitate the self-propelled guns, and I saw a thick barrel sticking out of the radar shell and pointing at the ten self-propelled guns more than 50 kilometers away.

Not good, all personnel evacuate quickly!

The commander shouted.

The ground combat crews reacted extremely quickly, and after all ten self-propelled guns were destroyed, more than half of them were evacuated, and those who did not evacuate were also affected by the explosion of the self-propelled guns.

Alas, failed again?

I couldn't help but shake my head and sigh.

Scientists have long warned us not to contact aliens, and look, people have come to the door!

At this time, just when people thought there was nothing to be done, another thick missile rushed towards the big radar with an even thicker tail flame. As if seeing something terrifying, the big radar shrank into a small ball, firmly wrapping the important signal transmitter in the center.

Rumble!

The missile exploded in an instant, producing a blinding glow and a huge fireball.

it! What missile is so bright?

I quickly covered my eyes with my hand, and within a few seconds, a strong air flow fell from the sky, blowing me off the ground, and I saw my house fly with it.

It's over, it's an atomic bomb?

I don't bother to think about what happened to my life, and it's a blessing that I don't die after I land. Sure enough, I lost consciousness after hitting the ground, and before I closed my eyes, I saw my house smashing down on me.

I don't see what happens next, but I'm going to tell you about it, because that's what people told me.

After the silver-white sphere was hit by the atomic bomb, half of the shell was melted by the heat in an instant, revealing the signal transmitter inside, and the melted part became dripping from the sky like molten steel. The other half quickly transforms, wraps around the transmitter, turns into a thick missile, and then, ignites, accelerates, and flies high into the air, out of the atmosphere, into the darkness of space, into the distant stars.

The parts of the radar that had melted into liquid as soon as they cooled to a solid body turned into dirt. When the people arrived, they saw only a few piles of dirt, not even half of the metal fragments.
