The cave was as always, but it wasn't much of an obstacle for eyes like mine, but the old witch wasn't so comfortable, and the winding tunnel was full of stairs, and it was inevitable that in the darkness it would be to step on the wrong steps, and if you were not careful, you would have to roll some distance. People are already old and small, and I can't bear to see them.

"Pull me." I said, I pretended to put the flashlight in front of me, I can't expose it now, I can see it clearly, and the dark team with the injuries on the snowy mountains is completely fine.

The old witch snorted, but eventually relented.

It was indeed very dark, it seemed that there was something absorbing light on the rock wall, and our flashlight was only less than a meter away, and the darkness engulfed the light, and it was impossible to see the road ahead.

The old witch pulled me, and the old black pulled the old witch, and the three of us moved forward slowly.

From the place where the old witch began to fall, the water of the stream actually began to change, "Contour line? I said to myself.

"What are you muttering alone?" The old witch said impatiently.

I didn't bother to talk to her, we had been walking here for a long time, but we didn't find the slightest clue.

"Did you find anything?" I asked.

"I can't see the fart, where did I find anything? But I want to ask if we're going uphill? There are places where I feel like I'm going up all the time, but why is this damn stream all the time? The old witch asked in a bird-like voice, and the voice of not paying attention to his face in the darkness was actually a little enjoyable.

"I can't see it, but the stream is always there. If you can't see the rest of the senses now, the senses will be more sensitive, so maybe we're really climbing. "I'm looking around intently now, but because they can't see, the sense of hearing and touch will be better used, and this place is so evil that it's not impossible for the so-called ghost to hit the wall.

"We're walking forward, and that feeling has taught me." I said.

I suddenly remembered that I had seen a video on the Internet, and the protagonist's life was actually a cycle, thinking that jumping out was completely played with by the Morbius of life or fate, and the video was very short, but the end was not the end.

The Möbius belt was discovered by the German mathematicians Morbius and Johann Listin, and the paper tape circle made by twisting a strip of paper 180° and then bonding the two ends together will make the strip of paper have magical properties. Ordinary paper tape has two sides, one front and one back, but the paper tape after twisting and connecting in this way has only one side, and if you put a bug in it, the bug can crawl over the entire surface without having to step over its edge. This kind of paper tape is called "Möbius tape", and the most common is the hair loop for girls to tie their hair.

When a Möbius ring is infinitely magnified, those ups and downs will become smaller and smaller, and once a person walks in, he is like a worm, never finding an end or a beginning.

If it were really like the old witch said, we would be in such a place right now. But the strange thing is when we walked in, isn't it the way we came in? I couldn't help but look back and see nothing out of the ordinary.

"Stop, there's a weirdness here." Lao Hei said.

I hurried to a halt.

"What's wrong? What did you find? ”

"There's a pit in this place, and if I feel right, we've already walked it three times!" The old black said as he writhed back and forth on the pit.

We crouched down and looked carefully at the potholes in the ground, and the ground was slightly tilted not far ahead, and I hurriedly stepped forward, the left and right sides were slightly tilted, and it was difficult to see with my eyes, and I was overjoyed, it seems that I guessed correctly, this is a Möbius belt.

"What did you find?" The old witch asked.

"We may have entered the Mobius belt." I felt the tilt of the ground.

"What's that?" Lao Hei asked puzzled.

Although this thing is common, it is estimated that few people know what it is called. I also happened to be bored to see it before, but now that I have met it, I really understand the power of this thing. It's almost a perfect trap, whether you can see it with your eyes or not, you can't believe that you've been going around in circles all the time.

"It's like a circle, but he doesn't make you feel like it's a circle, and if we can't find a way to crack it, we'll just keep going around in circles." I explained.

"So how did we get in? There's always an entrance, right? The old witch said.

This is also the most difficult part of my imagination, there is no trace along the way that shows that we have gone to the other road, we just follow the stream all the way to here, and the stream has been flowing like that without changing.

"I don't know? Recall what happened, too. ”

The three of us began to reminisce about what had happened since we left us. We didn't dare to take off the earbuds at first, but the strange thing was that the bell never rang, and then we all removed the earbuds for the convenience of communication, and then we just walked and walked all the way, and there were no forks in the door or anything like that.

"I see, it's not just the ring you said, there should be other mechanisms, like this hole under my feet." Lao Hei said.

"Potholes, yes, although the road surface here is high and low, there are no potholes, this should be a mechanism."

"Are you stupid that people would be so kind to leave you a switch?" The old witch looked sarcastic.

This old witch is really good at pouring cold water, I really doubt how she survived to this day, I am afraid that she has accumulated a lot of enemies in this terrible character.

I didn't bother to bother with her, so I walked to the side of the pothole, and found that it was actually full of sand, and I used both hands to clear the mud and sand out and see what was underneath, if it was really the switch of the mechanism that was just right for the old witch to slap in the face.

But no matter how much I pulled the sand, nothing changed in it, as if the sand was endless. To the mocking laughter of the witches, I finally decided to give up and collapsed to the ground, resting for a while anyway.

The old black saw that I was lying there, and he didn't care about the old witch's words, and began to clean up the mud and sand in the same way as I did. His hands were wide and fast, and there was soon a bunch of small sand dunes next to me.

I can't help but think that this old black may be a good excavator, and it is more reassuring to make more money than this.

"In the end." Lao Hei turned his head and said slowly.
