Confused, Brother Hao pulled me to the next intersection, just like just now, in addition to the tunnel itself, the other two tunnels are also engraved with arrows and H. Pen "Fun" Pavilion www.biquge.info

Am I blindfolded all of a sudden? Is the ghost hitting the wall? Or is there a parallel space here? I'm sure everything I've been through before that can be explained by science, but now it's a bit unbelievable.

We walked several intersections in a row, and the result was still the same, no matter how much we changed directions, nothing changed.

Brother Hao said in frustration: "It's over, completely lost!" ”

I was also a little hopeless, as if we would never get out. I sat on the floor and took a deep breath, gradually calmed down, and began to analyze the current situation.

First of all, it's certainly a labyrinthine loop, and if we put aside the possibility of supernatural factors, its structure is far more complex than we think. As it stands, each tunnel at each intersection is marked with markings, which means that we have walked every road, but every time we encounter a fork in the road, we only notice the exit markings, but ignore the two entrance markings, which leads us to the same intersection from different tunnels without knowing it.

This is the most likely, and if true, we are likely to be stuck in an endless loop structure. When I was a child, I loved to play mazes, the structure of the endless loop is the most difficult and very complex, it is composed of one or more closed loops, mostly found in hexagonal hive mazes. It is easy to find a way out at a glance from the floor plan, but when you are immersed in the scene, if you don't have enough spatial imagination and memory, you will often be trapped inside.

The flat loop structure can be solved by composing in the brain, but if this kind of loop is not two-dimensional, but three-dimensional, and each road will intersect and cascade at the spatial level, then it is difficult to achieve the composition with a sense of space alone, and the height and distance must be controlled to a certain extent, and few people can go out.

Not only are these tunnels meandering, but they also often have significant uphill and downhill slopes, so it's very likely that this is a three-dimensional labyrinth, and there is probably only one tunnel that can return to the normal route.

I told Brother Hao about this idea, and he nodded as if he didn't understand, and said, "So we are in a dead loop?" ”

I nodded, and he continued: "Then you think about it, you said that you loved to play mazes when you were a child. ”

"Brother, I'm just talking on paper, not to mention that the maze of real people and the ones drawn on paper are not the same level at all!" I replied angrily.

But his luck is really good, he didn't enter the dead circle when he came, otherwise with his unruly character, he could only be in a hurry, and he would definitely die of depression. But why is he so unlucky with me, and the fawn is the same, am I a broom star?

Brother Hao looked at me a little anxiously and said, "Preface, what should we do now!" ”

I didn't answer him, because I didn't know what to do, and if we couldn't find the only way, we wouldn't be able to get out at all, and we would waste our energy in vain. I suddenly realized the mood of Xiaolu's silence before, this is the silence that I don't want to disappoint my friend, at this moment, Brother Hao's hope is all pinned on me, and I don't want him to be disappointed.

There was an oppressive smell in the air, and my brain was racing, but I couldn't find a way to do it.

What would a fawn do if this were the case? I asked myself this in my heart. The fawn will definitely calm me down first, then analyze and think, and then ...... And then he took me out!

I think it's ridiculous, why is the gap between me and him so big, I was raised by my parents, I eat white rice and drink boiled water, why am I so useless!

Brother Hao on the side suddenly said: "I have a stupid way, I don't know if I can get out." ”

"You don't want to make a hole and get out." I teased.

He shook his head and said, "I've seen it on TV, you can keep walking along the wall on the right-hand side, and although you will take a lot of detours, you can eventually find the exit. We can also keep going through the tunnel on the right, we can always get out. ”

I understood what he meant, and said, "This method does not work for all mazes, only if the exit and entrance are on the outer wall, and it is a single-connected two-dimensional maze, because they are formed by two straight topologies, and no matter how the straight line folds, there is always a single passage connecting the entrance." However, this loop-and-loop structure doesn't meet any of these conditions, and it's not even certain if there are two gaps, so the approach you're talking about doesn't work at all. ”

I couldn't explain the concept to him without an intuitive pattern, and I don't know if he understood it, but I could clearly see a hint of desperation in his eyes.

I didn't want Brother Hao to feel bad, so I hurriedly added: "But this method is also worth trying, if the endless loop design has a slight loophole, if you are lucky, you may really be able to find an exit." ”

After saying this, I suddenly felt very slapped in the face, but I also had a bit of luck, in case the design of a certain road deviated, I really walked out.

We walked along the wall on the right, and after almost two hours, I don't know how many tunnels we walked, and we were still in an infinite loop. I sat on the ground exhausted, I really couldn't walk, Brother Hao seemed to be very energetic, looked at me and said, "Why don't we try along the left wall again." ”

I waved my hand weakly and said, "You're crazy! I can't walk anyway! This method will definitely not work, let's think of another way! ”

I suddenly felt a little broken, who had to dig a maze of dead loops and put it here, did he want to trap those dragon ants or protect the altar? But there's nothing in the altar.

Brother Hao looked a little depressed, sat next to me with his head down, and didn't say a word, as if he was stunned. I feel very sorry for him, the fawn didn't save him, but hurt him.

Suddenly, Brother Hao raised his head suddenly, looked at me with an unusually determined look, and said, "I have been walking along the wall on the left-hand side, since it is an endless loop, I will definitely return here." You just sit here and wait for me, and if I don't come back in two hours, you will come to me along the wall on the left! ”

With that, he tossed me the bag with compressed biscuits and water bottle. I held my bag and looked at him in amazement, not knowing what to say. Now, that's the only way.

But what if I can't find Brother Hao? I don't want to lose him again! I hesitated, and didn't respond for a long time.
