"Could it be that this sinkhole runs directly through the moon?" Xue Jun frowned, and couldn't help but guess: "The stone fell directly from here and fell into outer space?" ”

"Did you learn physics in vain?"

Xiao Jin rolled his eyes, with a look of disdain in his eyes: "Even if this sinkhole really leads directly to the other side of the moon, it is impossible for that stone to fall into outer space under the action of the moon's gravity, Sao Nian!" ”

"Oh, hey, that's it!" Xue Jun touched his nose and laughed.

Xiao Jin responded lightly and continued to fly down: "No matter how deep it is, there will always be a bottom, I don't believe that this sinkhole is really bottomless!" ”

"Okay!"

Xue Yu pursed his lips and flew down, anyway, the Cybertrons have been resolved, and things on Earth will not continue to deteriorate, now there is time to toss.

Keep flying!

1 hour, 2 hours

Gradually, 5 hours passed, but the sinkhole was still bottomless, and the bottom of the pit could not be seen.

"Our descent speed is almost 180 kilometers per hour, and we have landed for nearly five hours, and we have more than 900 kilometers, but we still can't see the bottom."

"Go on!"

All the way down!

6 hours, 7 hours

Gradually, 24 hours passed!

"Xiaojin, it's been 24 hours, and we've descended nearly 4,300 kilometers, and the diameter of the moon is only more than 3,400 kilometers, why haven't we seen the bottom of the pit?"

Xiao Jin glanced at Xue Jun, in the dark pit, its eyes flashed with golden light, and the thief brightened me: "Haven't you found it yet?" ”

"Found what?"

"We're not on the moon anymore!" Xiao Jin's words are amazing!

"What do you say, no longer on the moon?"

Xue Jun's eyes widened, a little creepy, and he looked around, and this look really found something different: the rock walls around him disappeared at some point, and in their place, there was endless darkness.

Yes, darkness!

There was a black rumbling in all directions, and you couldn't see any further away!

There is only darkness in the whole world!

Xue Yu couldn't help but be shocked, his whole body was cold, and he was so shocked that he couldn't speak: "Where is Xiao Jin now, are you lost?" ”

Get lost!

It's all dark, and there's no longer even the only reference to the pit wall, so how can you not get lost?

"It's not like you're lost!"

Xiao Jin's eyes shot out two rays of light, which seemed to dispel the layers of fog, and everything around him was invisible: "We have now come to a space that is completely opposite to the space where the sinkhole is located!" ”

"The exact opposite of the sinkhole space?" Xue Yu was stunned.

"Don't resist, I'll share my vision with you!"

In the next second, there was a slight roar in Xue Shu's mind, and there were a lot of things in his brain, Xue Jun looked at it again, and sure enough, he saw the "pit wall" around again.

This pit wall is exactly the same as the pit wall I saw when I came down just now, but it is upside down.

Yes, upside down!

"How can this be?" Xue Jun's face was shocked.

"As I just said, the space we are in now is completely opposite to the space where the sinkhole is located, and the position is completely reversed, just like when you stand in front of a mirror, the scenery inside the mirror and the scene outside the mirror are completely reversed!

Look at that stone, is it exactly the same as the stone we saw when we first entered the sinkhole? ”

"Yes, the stone looked like a cow, I remember it clearly, it was seen less than five minutes after entering the sinkhole!"

"Yes, what we saw five minutes after entering the sinkhole, according to the opposite principle, we are less than five minutes away from the real bottom of the pit!"

"Five minutes" Xue Jun understood a little: "This is the opposite, doesn't it mean that we go to the bottom of the real pit, and don't we return to the exit of the sinkhole?" ”

"That's right, but you have to know that although these two exits look the same, they are not the same place, just like when you go from a place outside the mirror to the corresponding place inside the mirror, it looks the same, but in fact it is two different places, but it just looks the same!"

"Really"

"Let's go, we'll be at the bottom of the real pit soon!"

The five-minute journey was fleeting, and as Xiao Jin expected, when the two came to the bottom of the real pit, they really came out of the sinkhole.

It's just that after leaving the sinkhole, what appears in front of me is another place.

"The whole sinkhole is actually a passage or corridor formed by a pair of positive and negative spaces, and after walking out of the sinkhole, we have now come to the real destination, that is to say, we have walked out of the sinkhole, out of the passage formed by the positive and negative spaces!"

"Here"

It was surrounded by a dark plain, vast and vast, but the sky was full of stars shining brightly, and the earth was dark, but it was not dark.

It's not the moon anymore, it's like another planet?

Xue Yu muttered secretly.

"What the hell is this place?"

Xue Yu flew up in the air, and he could feel the gravity from the depths of the earth, which was enough to prove that this was a planet, and it was still night, but the question was, where is this planet?

"I entered the sinkhole at the bottom of the moon, passed through a passage in front and back space, and came to such a planet!" Xue Yu muttered: "This positive and negative space passage is somewhat similar to a wormhole!" ”

"It's a wormhole in itself!"

Xiao Jin spoke: "You know what a wormhole is, a wormhole is just a passage opened up in the universe to connect two star fields, just like you earthlings dig a tunnel at the bottom of a mountain, how the tunnel is dug out, what style it is chise, how wide, how big, how long it is, it's all up to you."

In the same way, what the wormhole is made into is completely up to the person who made the wormhole, he wants to make the wormhole normal, then normal, he wants to make a positive and negative space in the wormhole to make a mystery, and let it be! ”

"It sounds reasonable, but can something like a wormhole compare to digging a tunnel?" Xue Yu muttered: "I'm afraid the technical content in this is completely incomparable!" ”

"What's incomparable, for you, digging a tunnel is very simple, in fact, for the kind of existence that can create a wormhole, maybe it's easier to dig a wormhole, you can't look at others with your eyes!"

Xue Yu frowned, and had to admit that Xiao Jin's words were very reasonable: "It's also true, it's a difficult thing for us, and for that kind of existence, maybe it's very simple!" ”

"Let's go, look around, what's so strange about this planet?"

"Wait, I'll mark this spatial coordinate!" Xue Yu activated the space super energy and casually made a spatial coordinate to mark the sinkhole so as not to get lost.

The principle of making spatial coordinates is like fiddling a few stones and piling them up into an arrow pointing in the direction, but the spatial coordinates are made of a special "arrow" with a space interlayer.

The materials used are different, and the principle is similar.

Once the spatial coordinates are made, Xue Yu can sense it and know that it is here, so that he will not get lost.

"Let's go!"

After making the spatial coordinates, one man and one beast found a direction and began to fly forward.

The sky overhead, the earth below, flying aimlessly, the planet is desolate, the ground is dry yellow, and at a glance, there is dry earth everywhere, no grass, no trees, no water, no animals, nothing.

There are only sparse stones, a few rolling hills, and endless sand dunes!

"The air is almost the same as the Earth, and the gravity is not much different!"

"It's night, and the temperature in this area is about minus 3 degrees Celsius, which is not cold!"

As he walked, Jin used his keen sense of smell to judge the information of the planet: "But it's too desolate!" ”

"It's desolate!" Xue Jun couldn't help but nod, entering this planet, it really feels very similar to the earth, especially the air and environment make people feel very familiar, but it is too desolate.

The desolate ones are a little uncomfortable!

Flight!

Aimless flight!

The speed of the two of them is very fast, almost reaching 500 kilometers per hour, and in just such a moment, they have flown nearly 100 kilometers, but everything they see can basically be summed up by the word "desolate"!

"Huh? That mountain is so high! ”

While flying, while looking around, suddenly, a black mountain appeared in Xue Yu's field of vision, this mountain is amazingly large, like a sharp sword straight into the sky, stretching for an unknown number of kilometers.

High!

Big!

"It's really high, we have to be at least more than 4,000 kilometers away from that mountain, and we can see it from such a distance, but it's very high!"

Separated by 4,000 kilometers, it is like standing in Guangxi and looking at the mountains in the northeast, can you see it?

Can not see!

Why?

That's because it's too far away.

But this mountain can be seen, which is enough to show that this mountain is too high and too big!

"This mountain and the largest mountain in the solar system, Mount Ospirin, have a fight!"

Xue Yu praised that Mount Ospirin is located on Mars, which is the highest mountain and the largest volcano that can be observed.

"Let's see!"

The surrounding terrain is not very undulating, relatively flat, such a high mountain towering there, it is too conspicuous, Xue Jun decided to go there to see, anyway, it is aimless, it is better to see this high mountain.

With the goal in mind, the speed can't help but speed up!

Two streamers crossed the sky, and half an hour later, they came to this high mountain, and when they really came to it, they could feel its majesty even more.

Too high!

Too big!

Compared to it, Xue Yu felt like an ant, slightly humble.

"What's that?"

Suddenly, something on the mountainside attracted Xue Xu's attention, and Xue Fei glanced at Xiao Jin and flew over quickly.
