I didn't think much about it, and I touched it about a few dozen meters forward, and the cave wall seemed to start turning, and I touched it, and found that the next cave wall was at an angle to the cave wall I was leaning on, and it was obvious that the cave wall began to turn. Pen, fun, and www.biquge.info

Continue to touch, something strange happened, the light source began to slowly approach us! After a while, the light source slowly moved away from us again! Just a little hesitating, Wen Jing suddenly pulled me and said softly: "Are we going in circles again?"

Hearing this, I thought about it for a while, and I was a little sure in my heart: that light source should be in the middle of this space, and we are walking around this space!

Wen Jing whispered to me, since this is the case, let's not go down the cave wall anymore!

In the dark, if you want not to lose your way, of course, you need to have a reference, and the light source in the distance is the best choice!

This time, we're moving in a straight line. Because I didn't dare to turn on the flashlight, I could only move forward step by step!

Soon, we slowly approached the light source, which seemed to be a protrusion, and a slightly bloated figure swayed from time to time. As the distance shortened, we slowly saw the scene in front of us clearly, and when we got closer, I finally breathed a sigh of relief: that light source was the flashlight in Hong Kaiyuan's hand! As soon as I saw that it was him, my anger was out of control, and I immediately shouted: "Lord Yama is asking for his life!!"

Hong Kaiyuan was muttering to himself at the moment, and was startled by my roar, and immediately shone the flashlight. He is not a timid person, and when he saw that it was the two of us, he immediately scolded: "You don't know, people can scare people to death!"

I was so angry that I still yelled, "You still know that you're scared, I can't wait to skin you alive right now!"

Seeing that I was really angry, Hong Kaiyuan hurriedly waved his hand and said with a sneer: "Old Qi, don't be angry! Listen to me!" Fortunately, seeing that he was unharmed, the stone in my heart had fallen, but I rushed to him and punched him hard, hitting him in the left shoulder, and knocking him back several steps!

Hong Kaiyuan was stunned, but he didn't get angry, because he knew that he shouldn't have slipped away alone. At that moment, he said: "Because I know that your old Qi is very wise, you must know what I am doing, and you know how to find me, so I acted on my own!"

Seeing him quibbling, I didn't bother to bother with him, so I asked, "What are you looking at?"

Hong Kaiyuan turned around and shone a flashlight at the place he had been observing just now: "Look for yourself! It's so weird!"

At this time, Wen Jing also came to the two of us, I took the flashlight from her hand, and also shone at the place where Hong Kaiyuan pointed, under the light of the two flashlights, I saw a strange thing.

To be exact, it looked like a stone platform, the surface was granite, its outer façade looked like a column, about two meters in diameter, about one meter five or six high, and there was no gap between the bottom and the ground, and there was nothing unusual, as if it was an oversized stone pillar growing from the ground!

"Lao Qi, don't patronize and look outside, the weirdness is inside!" Hong Kaiyuan saw that I had been staring at the outside of the stone platform, and he was a little anxious. "Hurry up and take a look, Lao Tzu didn't see the reason for watching it for a long time!"

So I approached the stone platform, and with my height I could see the top or the inside of the stone platform.

Because at the top of the stone platform is not a plane, but a bowl-shaped structure that gradually concave from the four sides to the middle, it is said to be bowl-shaped, because the whole process of concave does descend and shrink inward like a ladder, but the surrounding area is not a whole spherical or curved surface like a bowl, but is divided into eight trapezoidal independent surfaces, much like the assorted boxes used to hold food in ancient times!

I counted carefully, and there were a total of twenty-five sides on the inner surface of this bowl-shaped groove, divided into three layers, each with eight sides, and a regular octagon in the middle. Looking at the edge of this stone platform again, my heart is a little strange!

Because the texture of the stone on the outer façade near the stone platform is completely different from the inside of the stone platform, and the inside does not look like granite, because I scraped it with my fingernails and found that this part of the stone platform actually has a metal-like reflection under the light of the flashlight, and the entire edge of the stone platform is irregularly jagged. I walked around the stone platform, carefully looking at the jagged structure around its perimeter, and suddenly a strange feeling welled up in my heart.

I came from a mechanical design background, and a lot of my thinking was limited to mechanics. Of course, there is a reason why I said this, because the biggest reason why I chose to major in mechanical design back then was that I had become obsessed with mechanical things and even became obsessed with them. My father wanted me to study medicine, but I went against the image of a good son and chose the major I wanted without hesitation!

Therefore, after reading this stone platform, I felt that this thing should be matched with something else and have a specific purpose. Because no matter how I look at it or think about it, I always feel that the structure of this stone platform concave surface is a complete assembly surface!

I think that the thing that was originally contained here was separated from it for some reason, and that thing that matched with it, after cooperating with it, should be covered with a layer of granite-like substance for some purpose, so that the two are completely one and the same from the outside, and it feels like a camouflage.

Thinking of this, I bent down and circled the ground around the stone platform. He also took out a small hammer that he carried with him (I couldn't buy a mountaineering pickaxe in a small place, so I bought a hammer to fill up at that time.) ), knocked on the outside of the stone platform.

"Hey, Lao Qi, are you pulling the grinder?" Hong Kaiyuan on the side was obviously a little impatient with my actions, and said loudly: "Do you see anything?"

I ignored him, straightened up, and looked at the inside of the groove, which had accumulated a layer of dust that was not too thick.

Thinking about it, I slowly touched the dust on one of the eight trapezoidal surfaces in the outermost circle, and it seemed that the inside of the hole was indeed clean, and the dust was less than half a millimeter thick. Soon, I saw the situation inside: the trapezoidal plane was glowing with a slight reflection like metal, and there were a few small holes distributed on it, and there seemed to be no regularity, and there seemed to be some regularity, and I couldn't help but feel a little discouraged after looking at it for a long time and not seeing a reason.

"How is it, is there a result?" Hong Kaiyuan asked when he saw that I had stopped.

"No!" I was a little frustrated, "you haven't seen anything for hours, I'll see what I can see for a while?"

"You two are still bragging about being the smartest people, and now you have only seen a little corner, of course you can't see anything!" Wen Jing, who had been silent, suddenly spoke.

"yes, I didn't think of that. Climb up and clean up all the inside, won't you see it?!" Hearing this, Hong Kaiyuan patted his head and immediately prepared to go up, and handed the flashlight to Wen Jing: "Sister, you help me hold it!"

Seeing this, I hurriedly grabbed him: "Could there be any mechanism in this?"
