Two hundred and ten,

After deliberation, it was unanimously agreed that they should go through the hole under the stone slab, instead of following the path from which Ge Huaiyi had come to find a new exit.

The first step is to make a hole.

This time, Li Jingfei was finally able to see with his own eyes how Ge Huaiyi's equipment was drilled.

I saw Ge Huaiyi approaching the stone slab, sticking his palms on it, and giving an order to the artificial intelligence in the helmet. Then his protective subordinates came out of their elbows with two black hoses sticking out of each of them, and there was a suction cup on the tube.

When the four suction cups are attached to the slate, the edges begin to shake constantly.

Li Jingfei understood at a glance that this was using resonance to test the density of this stone slab, so as to choose the strength to penetrate him.

It's just that listening to this sound, it is a little different from what Ge Huaiyi tested next door to the mountain wall just now, not because the material of the slate is different, but because the frequency of the test is different, and it is much slower.

"Why is the frequency so low?" Li Jingfei couldn't help but say.

Fan Lingwei on the side replied: "The frequency is adjusted according to the force transmitted back by the vibration. If the frequency is low, it means that the density of the slab is not as high as the mountain wall, and it should be easy to penetrate. ”

At this time, the test was over, and Ge Huaiyi took a few steps back, still stretching out his hands. This time, the position was aligned with the small hole made by the snake.

At the elbow joint, four more hoses protruded, extending one meter around the hole along with the previous two hoses. However, this time, the raised metal cone in the middle of the suction cup was firmly fixed on the stone slab, and the palms that were originally facing forward were also clenched into fists.

With a "weng" sound, two shockwaves hit the stone slab with two shockwaves from both fists at the same time.

There was a bang, and the stone slab was blasted out of a hole more than a meter long and wide in front of everyone.

The effect of this time made everyone stunned, they didn't expect the equipment on Ge Huaiyi's body to be so powerful. But the strange thing is that not only others, but even Ge Huaiyi was stunned.

According to the exploration just now, the density of this stone slab is not large, and the force just now is calculated, which can completely ensure that a large hole for one person to enter and exit easily. But what is this now, it is estimated that it will be difficult for a strong dog to get in.

For these, Li Jingfei naturally didn't know, he and Fan Lingwei, who first came back from the shock, came to Ge Huaiyi's side and said: "It's dangerous and unknown inside, we have equipment on both of us, it's better to go first and take a look, if it's okay, let the others in." ”

Ge Huaiyi waved his hand and said: "This slate is strange, with the strength I used just now, I can make a bigger hole, but now the hole is so small, which shows that the density of the slate is greater than that tested by the instrument." ”

"Is it because you don't have enough energy on your equipment to measure the full density?"

"But if the density is greater than the test, I won't be able to make such a big hole with that blow. ”

"What's the matter, is there anything wrong in this cave?" Behind him, Professor Zou asked when he saw that the three of them were slow to act.

The three of them didn't speak loudly, but they were afraid of affecting the people behind them, especially Zou Song, his character, when he heard the conversation between the three of them, he would definitely come up to study the structure of the slate.

"It's nothing!" Li Jingfei, who reacted quickly, immediately responded: "We are just discussing who will go first to explore the way next." After speaking, he continued to say to Ge Huaiyi: "You have offensive equipment on you, you go first to explore the way, I will answer at the entrance of the cave, and Fan Lingwei will stay to protect everyone." ”

After the discussion, the two began to prepare. Li Jingfei took out a small safety rope from the equipment on his body and fastened it around Ge Huaiyi's waist, while Ge Huaiyi leaned down first, took a flashlight and took a picture of the hole.

"Looks like we're mistaken. Ge Huaiyi shone the inside with a flashlight and said: "This is not a stone slab, but a stone pillar, a hollow stone pillar. ”

"Stone pillar?" Li Jingfei listened, and also leaned down and took the flashlight to shine inside.

Sure enough, it was their preconceived delusion that they mistakenly thought that this was a stone slab, and the stone pillar in front of them was built against the mountain, and most of it was inside the mountain, only revealing the outermost layer of the pillar wall, which made people mistakenly think it was a stone slab.

The inside of the stone pillar is not small, its length and width are the same, and if everyone can't get out for a while, it is possible to spend the night in it. The floor is also artificially paved, and the material is the same as that of the surrounding area, which is made of cement. The only difference is that the inner wall has been polished and appears smoother.

"The air inside is fine. When Li Jingfei irradiated the inside of the stone pillar with a flashlight, he also measured the air inside.

Get ready, Ge Huaiyi bent his waist and drilled into the slate cave.

I don't know if it's a coincidence, or if it was intentional when it was originally designed, drilling in from the position of the hole, the light is just reflected back no matter which angle it shines on. And when Ge Huaiyi entered the stone pillar, it was also the time when the light was the most dazzling. Instinctively, Ge Huaiyi closed his eyes slightly.

When he opened it again, the person was already inside the stone pillar, and the scene in front of him shocked him again. The pillar of light, which was originally straight ahead, did not shine on the wall in front of him, but shot into the endless distance.

What is the situation, when you look at it from the outside, the bottom area of the stone pillar is not so large, and you can't see the head, only the height of the top.

Thinking of the height, Ge Huaiyi immediately raised his flashlight and pointed upward. Sure enough, four or five meters above the head was the ceiling, not an endless passage leading to the sky.

Could it be that they were wrong again this time, in fact, the internal space of the stone pillar is not all hollow, only a few meters above it is hollow.

Although this can explain the phenomenon overhead, how can we explain the scene in front of us? Could it be that there is a light-controlled laser inside this stone pillar, and once it is illuminated to a certain extent, the wall in front of it will be opened and a passage will appear.

Thinking about it this way, although it seems to explain everything, there is another key issue that is not clear, and that is weight.

From the outside, this stone pillar is so high, it is still solid, and it can collapse at any time when pressed into such a cement stone room. But when I put a flashlight at the ceiling, I couldn't see a single crack.

"Hey, are you still there, can you hear it?" Just as Ge Huaiyi was about to further prepare to study the environmental structure here, he heard Li Jingfei's shout coming from overhead.

Ge Huaiyi was stunned when he heard this, why did the voice come from above his head? Shouldn't they be outside the cave behind them?

Hurriedly turned around and bent down to look, and sure enough, it was pitch black outside, and there was no half a figure.

What is the situation, is it possible that the space here is at a ninety degree angle to the outside? There was a mess in my head, I couldn't think at all, and the voices outside continued.

Anyway, let's get out first.

When Ge Huaiyi poked his head out, he found that everyone was gathered around the entrance of the cave, and all the flashlights were turned on.

"What's the situation?"

After pulling the person out, Ge Huaiyi and Li Jingfei asked in unison.

"What can I do here, it's you. When you go in, there is no movement at all, there is not much space inside, but I scanned it a few times with a flashlight, and I didn't see you. ”

"Really, when I went in, I saw that the environment in front of me had changed......

Listening to Ge Huaiyi talk about the scene inside, everyone also suspected that the space inside was folded in half to ninety degrees, but this situation was too incredible.

"Otherwise, let's go in and have a look. When the two professors heard about the space folding, although they were not professional, they were immediately interested.

"Don't be busy, you haven't figured it out yet, it's possible that there is such a mechanism in it. Otherwise, I'll go in and have a look, and this time I won't turn on the flashlight to see if I won't touch the mechanism. ”

Li Jingfei and Ge Huaiyi came to the entrance of the cave again and asked, "Do you think this is really caused by some mechanism?"

"When I was inside, I was hoping it was caused by the mechanism inside. But when I heard you say that you used a flashlight to shine on the inside, you didn't find anything, and you didn't hear any mechanism activated, so I thought it might not be a mechanism. But if it is explained that it is a space folding, I can't accept it, so I want to try again. ”

"What's so unacceptable about this, you have been exploring for a long time, and you have encountered all kinds of strange situations, such situations should not be strange. What's more, now that the whole world recognizes the existence of supernatural phenomena, even the monster attack on the city has happened, and this space folding is within the scope of bearing. ”

"I think I've experienced a lot of weird events, but I can't immediately accept the fact that the space in front of me is folded, but you can face it with a smile. This means that either you don't believe it at all, you just don't want to show it too obviously, or you know what goes on. ”

"So which one do you think it is? ”

"I think you've had an even more incredible time. ”

This time, the two discussed, or Ge Huaiyi went in alone, but this time he didn't turn on the flashlight, but let Li Jingfei shine behind him to see how Ge Huaiyi disappeared.

Li Jingfei knew that he had a great responsibility, and whether he could see the mechanism behind the cave this time was all up to him. Ge Huaiyi didn't use a flashlight this time, the scene inside couldn't be seen, and any slight changes were captured by Li Jingfei. Just in case, he also increased the range of direct light from the flashlight, just because he was afraid that the mechanism would be activated from the periphery.

Ge Huaiyi bent down, squinted his eyes and burrowed into the cave as before.

The sensitivity of the ears in the dark will be greatly improved, and this time Ge Huaiyi is more careful, he can feel it whenever the wind blows.

But this time he didn't feel anything, it was dark when he opened his eyes, and Li Jingfeng was said to be illuminated behind him, but at this time, there was no light behind him. In desperation, Ge Huaiyi had no choice but to turn on the flashlight by himself.

Inside, the situation is the same as before, there is a cement slab overhead, and there is a passage in front of you with no end in sight.

Li Jingfei's voice came from above his head again.

Ge Huaiyi sighed helplessly, so he had to get out again.

"What did you find outside?"

"No, I kept shining a flashlight behind you, and at first I could still see you, but at the same time you entered the cave, my light was completely swallowed up by the cave, and I couldn't even see the opposite wall that could have been illuminated. ”

"Could it be that your flashlight has been used for too long, the battery is not enough, and it just happened to be out of power for a short time at that time. ”

"Okay, let's not kid ourselves, my flashlight is the one you got and hasn't used yet, and I've also increased the range of light, and by the way, the walls around the cave have also shone on. At that time, it was only the light that hit the cave, and the light that shone on the walls on both sides was still there. ”

"There are no artificial mechanisms, pure supernatural phenomena, this is not easy to deal with. Ge Huaiyi was a little overwhelmed.

"It's not necessarily a bad thing, at least we have a chance to get out. ”
