If you take the first equilateral hexagon as the center, the six equilateral hexagons around it can be regarded as the second layer, and I can now clearly see that the third layer has twelve identical equilateral hexagons, but I can't accurately represent them in my mind. I can only look for that inspiration in this existing image.

What is it? My mind wandered through these linear passages, and I could instantly move between the known images, but the feeling that made me suddenly never appeared, and I was like a clumsy and ignorant toddler, shuttling through the imaginary passages in a daze.

For a moment, a way, a stupid way, came to my brain.

If my idea is true, of course, this needs to be verified. We can take this hexagon in the middle as the center and search outward layer by layer. In the end, it is possible to find the exit, at least Xiao Guolin and their traces can be found. But this was by no means my original idea, and although I can't find it anymore, I'm sure it's a completely different idea from my original idea.

This idea is not very feasible, and our lighting does not allow us to explore for a long time. Unless we give up the lighting and explore in the dark. This is too inefficient. When my mind is complicated, I can't concentrate, and the images can't be complex and concrete. I had to let go of this stupid method, let go of complicated thoughts, and concentrate on drawing my map in my head.

But it was getting harder and harder for me, and I found it hard to concentrate so much ever since I was disturbed by that strange sound. When I was so distressed that I almost collapsed, there was a little fire in the passage in front of me.

I looked at the approaching firelight with mixed feelings, a little nervous, a little expectant, and a little panicked, because under this firelight, it may be Platoon Commander Zhao, or it may be, Xiao Guolin.

When the firelight approached a certain distance, I shouted, "Is it Platoon Commander Zhao?" ”

The firelight flickered, and Platoon Commander Zhao's scolding voice came: ", Brother Qiang, are you going to scare us to death?" How did you put out the fire? ”

With the sound coordinates, the speed of the two people increased, and they soon came to me. I looked at the tired looks of the two of them and explained, "We need to save fire, I'm waiting here alone, with or without lighting." ”

"We didn't find the marks left by Xiao Guolin at that fork, where are you?" Platoon Commander Zhao saw me and first asked him the question he was most concerned about.

I shook my head and said, "Didn't find it." But I have an idea. ”

Then I spoke my mind. Of course, I also said that in order to prove this idea, I have to take a risk and go around it.

Platoon Commander Zhao immediately took a hard object and drew a crappy hexagon on the ground. Then he drew a second hexagon along the line that was divided to represent the fork. I glanced at this miserable picture, worried that my thoughts would be carried into the ditch by it, and hurriedly raised my head to look at squad leader Liu.

At this time, we can see the difference in everyone's spatial imagination. Team Leader Liu never glanced at the picture drawn by Platoon Leader Zhao, and had already entered a meditative state. In a moment he suddenly exclaimed, "Is this a hive? ”

it, I had a bang in my head. That's right, that's what first flashed into my head.

But I immediately came to my senses, shook my head, and said, "I have this assumption too." But judging from the path we have explored, it should be a plane, not a three-dimensional structure. ”

"Are you sure?" Squad leader Liu pointed to the top of his head and said.

What's the doubt about this? I looked up at the top of the cave, and it was pitch black. I took the torch from Platoon Commander Zhao, who was still squatting on the ground and drawing circles, and raised it to the top. The roof of the cave was still strangely pitch black. I thought about it, the cave was very high, but when I raised the torch to the top, I could still see the top of the cave. This fork in the road is not visible, what is going on? Hell yes.

I jumped a few times with my torch in the air, but I couldn't see the top of the cave. I couldn't help but ask squad leader Liu: "When did you find out?" ”

The flesh on squad leader Liu's face trembled a few times. "When you pass by the first fork."

"Then why didn't you say it earlier?"

"Say what? Didn't I see the roof of the cave? ”

…… I was so angry with him that I couldn't speak for a while.

Yes, anything that would cause panic at that time would have been unwise to say. I can't condemn him on this issue, but it still upsets me that he has artificially ignored this information. This has the potential to mislead us in the direction of our actions. But what now? After being told the problem that bothered me by Team Leader Liu, I found that it did not help us get out of the predicament, but made the situation more complicated. In fact, if you think about it a little, you will see how unrealistic this idea is. No matter what the original intention of building this channel is, it is of no practical significance to build it into a three-dimensional honeycomb structure. It's hard to imagine how difficult it would have been, at least I don't think their civilization would have been able to do it thousands of years ago. Although I cannot give a convincing explanation for the height of the roof of the tunnel at the fork in the tunnel exceeding the height of the passage, vague and uncertain speculation is possible. For example, each fork will be the key area of construction, personnel, equipment, earth and stone will be distributed here, especially some large excavation equipment, will be assembled or disassembled here. That would require a relatively high space.

After I told this speculation, I immediately got the support of Platoon Commander Zhao, who believed that this explanation was correct and reasonable. But squad leader Liu shook his head and said, "What if that's the case? He put his two hands together, crossed his fingers as if he had pinched a nest in his palm, and with his movable right arm, he placed this nest somewhere in the space, and then pinched the other one in the same way and placed it in another place in the space. I watched him constantly place imaginary objects in the void, and my brain couldn't help but be engrossed, otherwise I wouldn't have been able to keep up with the pace of his thoughts. Before my eyes, no, I should say that a complex model appeared in my mind: a huge, three-dimensional beehive. Of course I knew it wasn't possible. In fact, the honeycomb is a single-layer six-sided cylindrical structure, and it will not be the three-dimensional structure imagined by squad leader Liu. Of course, he could have assumed layering, but another problem came to the fore, and his assumption was that the stones surrounding these passages were like the space inside the hive, and the passages were like the walls of the hive. Judging from his movements and my understanding, the nest head that he pinched out to indicate the space in the hive is completely independent and suspended in mid-air, which is also different from the actual situation. I immediately pointed out to him that his hypothesis was not true. I pointed to the imaginary nests he had placed in the void and said, "First of all, it is impossible for these nests to exist independently in the air, which is contrary to common sense and inconsistent with the current reality. Also, you can't realize this idea, and this amount of engineering and engineering difficulty are impossible tasks for that era. "I'm pinching zongzi." Squad leader Liu seems to care more about calling his work a nest than denying his overall ideological works.

PS: Happy parental leave. I'm going to go out in a minute, there's only one chapter today.
