If Ah Xue was kidnapped, then she would not have been able to go where she had been.

But I believe she left on her own.

With Ah Xue's skills, it is almost impossible to kidnap her silently, unless she really meets an alien.

But if there really were high-level intelligent beings other than Earth coming here, then it would be impossible for Sildra to find nothing.

This place, she is most familiar with, should be my apartment.

But I've been to that place before, and there's no shadow of Axue. What else would she go back to besides that place?

I even wondered if the person who went to my apartment yesterday to rummage through things could be Ah Xue?

Isn't the person who rummages in an apartment the same person who turns things in a villa?

Of course, in the absence of sufficient evidence, everything is just speculation.

Am I going to go back to the wormhole now? Follow the route we escaped from that year?

As soon as his mind moved, he summoned the Miao Knife and prepared to fly in the direction of the wormhole.

But at this moment, a squeaky sound pierced the night sky and interrupted my train of thought.

This is...... The sound of the walkie-talkie?

Did it find a signal?

Is it a signal from Ayuki? Or is it a signal from other walkie-talkies?

I couldn't wait to take off the walkie-talkie, and when I looked at the slightly flashing indicator light on it, I began to wonder in my heart.

The walkie-talkie did find a signal.

But the signal was very strange, and there was no human voice coming from the speakers, nor did it look like a squeaky noise when there was no signal.

It's a very quirky signal, it has no content, but it has a lot of content.

In the speaker of the walkie-talkie, a rhythmic, regular note is being emitted...... A note that people can't hear at all!

Is this a password? Or is it a signal from outer space?

I thought for a moment, then said, "Sildra pinpoint the place where this electromagnetic wave is coming from." ”

"Yes! Master! ”

In the military, the telegraph was still used.

The reason is simple: the code transmitted by radio is not easy to decipher.

I want to see if this strange radio station is a password from a military base, or a signal from Ah Xue's walkie-talkie.

The walkie-talkie she gave me is really weird, and it has far exceeded the function of ordinary walkie-talkies.

Soon, Xierzhuo came up with an answer, but her expression was a little uncertain.

"What's wrong? Can't locate it? ”

"Hmm!" Xierzhuo looked at the horizon and said strangely, "Master, I really can't locate it." This is somewhat abnormal. In general, the location of a radio station can be determined as long as there is a radio coming out. Although the other party sends a pulse signal, it is intermittent, but after a long time, it will always be locked.

But...... Today's ...... It's really hard for me to say what's going on. ”

She thought for a moment and said, "Let me put it this way, when I received the first pulse, I could only get a straight line. And the radio must be on this straight line. At this point, I need to change positions and wait for the second pulse to be received. In this way, you can get another straight line, and the place where the two straight lines intersect is the position of the radio station.

But the first set of lines I measured didn't intersect at all. They're parallel! Just when I thought it was a signal from two stations, a second set of data appeared, and this time, two straight lines intersected. But...... Master, do you know where the intersection is?

Right in your villa! ”

"My villa!" I was taken aback, "How can there be a radio station in my villa?" It's still a radio station that is always emitting signals to the outside! ”

"Impossible!" I outright no. I didn't have any hope for this electromagnetic wave, but now I have to face it squarely.

"I also knew it wasn't possible. That's why I say it's weird. Master, this is not the weirdest thing, the weirdest thing is that when I measured the position of this station for the third time, it ...... It's right at your feet! ”

"Under my feet? Hildr, you're not mistaken, are you? ”

"It's impossible to be mistaken. Master, this radio station...... It seems to be moving, but it's moving too fast. It's simply not possible. I feel like we're running into a very tricky problem right now.

There is another thing that worries me the most. ”

I listened to her finally say this, and I couldn't help but frown: "You mean that a guy who we don't know about is approaching us at a crazy speed?" ”

"Hmm...... Host, it turns out that you have thought of ......"

In reality, there are no absolute parallel lines, just as there are no parallel lights...... Even if it is the best parallelism, it cannot be absolutely parallel.

Let's talk about this in terms of projections in drawings. If a point light source is very close to the projected object

, then the difference between the projection on the projection surface and the projected object is very large, but when the distance between the point light source and the projected object is infinitely larger, it can be infinitely close to a parallel light source, and the projection at this time can be regarded as a parallel projection.

In parallel projection, the physical object and the projection are exactly the same.

The first time Hildra said that two straight lines are parallel, it means that this station is still very far away, and in the case that Hildra is not moving a very large distance, these two lines are one parallel line...... At least two lines that are very close to parallel.

By the time of the second and third measurements, the two lines had already crossed and were getting closer and closer to us.

This means that the other person is approaching me at an almost terrifying speed.

It's like saying that one second the radio is still on the moon, and the next second it is on Earth, and the next second, it is already at my feet.

This...... No way!

How is it possible for a radio station to fly at the speed of light?

The fastest object in this universe is light!

One second can circle the earth seven and a half times.

If the other party is really light, then they can indeed get close to me at such a terrifying speed.

But the problem is that the reason why light can have such a fast speed is because photons have no mass!

In reality, it is impossible for any object with mass to move faster than the speed of light.

This is true on the planet, and it is true for us there.

When the speed of an object is close to the speed of light, the energy will gradually be converted into mass, which means that the mass of the aircraft will increase.

The mass of the aircraft increases, which means that the engine needs to provide more thrust.

And after these thrusts accelerate the aircraft, the mass of the aircraft will increase again. In this way, we enter a vicious circle, and it will never be possible to break through the speed of light!

In our case, the most we can do is to use the powerful gravitational field to distort time and space, and create short space tunnels to achieve the purpose of quickly crossing the stars.

This radio wave is really weird.

It's a little cold on my back.

I looked down at my own reflection in the river, I don't know when, my face had turned pale.
