I don't know what he saw, but his expression was very ugly. This made Li Ling also couldn't help frowning, and slowly walked to Lin Xiao's side.

"What is this?" It's just that when she walked over, she immediately showed the same expression as Lin Xiao, and even said the same thing as Lin Xiao.

There was no way, what they saw in front of them really didn't happen to the two of them.

They thought it was a world full of alien creatures, but in fact they saw nothing but a blue-scaled snake.

Originally, they thought it was an inaccessible place, but now they felt that this was not the case at all!

From the outside, it was just a hole, but when they came to the hole, they saw that there was a pipe inside the hole.

That's right, it's a pipe made by hand.

I don't know what the material of the pipe is, but the workmanship is excellent, shining silver, and it is in a very perfect cylindrical shape.

And a little deeper in the pipe, there is also a fan, which is only slowly turning, but it is enough for exhaust.

Behind the fan, you can clearly see the pipe winding upwards.

"Anyone?" After the initial shock, Lin Xiao and Li Ling came back to their senses at the same time, and after glancing at each other, they said the same word again.

There must be someone, and this pipe looks like it was carefully forged by man, no matter how you look at it.

In this place, which is considered a forbidden place by the entire Sandar Star, there are man-made objects. And the pipe doesn't look old, if it's not new, it's definitely maintained.

That's just so abnormal.

So, Lin Xiao turned his head to look at the Mars people on the side, "You used to go up from here?" ”

The mountain wall that the Mars people had asked Lin Xiao to climb before was less than ten meters away from the horizontal position of the cave entrance.

The Mars people looked at Lin Xiao and Li Ling strangely, not knowing what was wrong with the two of them. But he nodded his head anyway, "That's right." ”

"Did you see anything unusual when you climbed up?" After a pause, Lin Xiao changed his words again, "Like a house or something." ”

If the pipe is really man-made, then the place where it is connected must be a human structure. If there really were human buildings, Lin Xiao and the others would certainly not have to climb up from here at all.

The Mars people shook their heads at Lin Xiao without even thinking about it this time, "House? How is it possible to have a house? I didn't see anything but the mountain wall anyway. ”

"Is it hidden in this mountain wall?" Li Ling hurriedly said to Lin Xiao.

Without waiting for Lin Xiao to speak, she opened her hand, and the black particles quickly converged from her hand, and finally condensed into a strange prop.

The prop is divided into two parts, one of which resembles a small trumpet, but is nothing more than rubber.

Others are just small tablets. There is nothing connected between the two parts, but it is still clear that it is a set. Between these two parts, there should be signal conduction.

After taking this thing out, Li Ling put the trumpet-shaped little thing on the mountain arm, and then pressed it lightly on the tablet on the other hand.

Suddenly, the screen of the tablet appeared, but it was a virtual block. You can also see that the whole block is spreading rapidly.

Lin Xiao is also a hacker and a thief, so of course he has studied these high-tech things. Otherwise, he wouldn't have been able to cultivate, and he would have to let Huang Mao prepare many high-tech products for him.

He only glanced at it briefly, and then he got a rough idea. This is supposed to be a scanning device, most likely sonar. That little trumpet-shaped thing is the product that conducts sonar.

It's a fairly old technique, but it has to be said to be very useful. Especially to explore the mountains.

"Hmm!" Only two or three seconds passed, and the tablet in Li Ling's hand suddenly went black, Li Ling snorted slightly, and then turned his head to look at Lin Xiao, "The sonar is blocked, there is really something in this mountain wall." ”

"It should be some kind of force field, if there is really a building in this mountain wall, it should be a protective force field."

"Force field?" Lin Xiao paused slightly, and immediately remembered that when he first fell into the valley, he tried to fly up with a jetpack, but a layer of light curtain and lightning suddenly appeared at the mouth of the valley, and now that he thinks about it, it should also be some kind of force field.

There is a strong field on the surface of the valley, and there is also a strong field in the mountain, Lin Xiao can basically be sure that there must be human buildings on the surface of this mountain.

Of course, Li Ling is also sure.

She put away the props in her hand and pointed to the pipe in front of her, "You can definitely get in through this pipe, do you want to go in." ”

Before, Lin Xiao would definitely nod without hesitation. But now, he didn't act rashly.

First of all, the Psychedelic Valley is a forbidden place, but someone built a building here, and no one knows about it until now? This is very abnormal.

At the edge of the valley there is a strong field of protection, to prevent things here from going out. And the buildings in the mountains are also protected by strong fields, which is even more abnormal.

Lin Fei shook his head and muttered in a low voice, "It's not sure that this is a military base, it's not a scientific research institute, and it's even more difficult that this is a place where a certain criminal organization was established, there are too many possibilities." ”

"If we get in and meet good people, that's fine, but if we meet bad people, we lose our lives."

Couldn't help but look up at the mountain wall not far away, compared to climbing into this pipe, Lin Xiao still felt that the mountain wall was much safer, after all, only to save his life was the right way.

Li Ling took out another lollipop and thought about it after holding it in his mouth. Although she is a little proud, it does not mean that she is a stupid person, and she also knows very well that what Lin Xiao said is completely true.

She was also thinking about what to do.

"Mmmmmm Just as they both fell silent, a soft sound suddenly came out. This voice was very low, and it sounded a little uncomfortable, at least Lin Xiao and Li Ling immediately frowned.

The combat uniform on Li Ling's body immediately wrinkled, and Lin Xiao couldn't help but urge Yuan Li to instinctively protect himself.

Only the Namars, whose eyes lit up when they heard the voice.

He raised his hand and slapped it heavily, and his eyes showed excitement at this moment, "Great, you want to eat?" ”

"Open dinner?" Lin Fei and Li Ling both turned their heads to look at him strangely.

It's just that just as the two of them were talking, suddenly there was a faint sound of 'bang, bang, bang' from the pipe.
