My prophecy has come true! Nangong and I walked back to more than sixty stone chambers, but we still didn't see the cave that Nangong said, and the two of us fell into this dead knot.

Nangong now felt the same way I felt when I encountered the Death Loop before, and my heart was almost broken. I've been through this before, and I'm not so hopeless now.

I told Nangong all my previous speculations, and after Nangong listened to my speculations, his mood gradually recovered. is worthy of being a police officer, and her ability to accept is not a little bit stronger than mine.

After listening to my reasoning, Nangong put forward a bold idea, but this idea made me feel a little frightened and even a little repulsed. Nangong's idea is that the two of us are separated, one is waiting here, and the other is walking in one direction. If these stone chambers are not endless, then no matter what mechanism there is in this stone chamber, the person who walks will eventually walk out of the other doorway.

I discussed it with Nangong, and she now consumes more physical strength than me, so I asked her to wait here. I walked in the direction that Nangong came in, and if I still didn't see Nangong in more than a hundred stone rooms, I turned around and walked back.

To be honest, when I was with Nangong, although I was desperate in my heart, I was not particularly afraid. And when I began to walk alone through the stone chamber again, the fear that I was the only one in the world slowly came over me.

I counted the stone rooms one by one and walked forward, but after walking more than fifty rooms, I still didn't see the shadow of Nangong, although I told Nangong that I would walk back after walking through a hundred rooms, but to be honest, I didn't have any hope of being able to see Nangong ahead.

Just as I counted to sixty-three and walked mechanically towards the sixty-fourth stone chamber, I found that a person was looking at me excitedly, it was Nangong!

We finally got to know the stone chamber a little, but how did I get behind Nangong? Could it be that there really is a spatial wormhole in this string of stone chambers? As I passed there, I reversed the direction and walked back slowly? If I'm not mistaken, the stone chamber must be thirty-two.

Nangong was also a little excited when she saw me, and she didn't understand why I would appear behind her when I walked forward. She asked me for details about the way I had come. I told her everything, including the number of stone chambers I had walked through and my own inferences.

Nangong didn't deny my reasoning, but sat there thinking about it for a long time, and then said to me: "Maybe we imagined things too complicated, but the organs here are actually not as complicated as we thought. ”

I looked at Nangong with a frown, but I didn't know what she wanted to say, everything here was almost completely beyond my thinking ability, and I couldn't even think of any possible speculation about the current situation. But Nangong said that the mechanism here is not so complicated, could it be that she has already seen what is going on here?

Nangong saw my expression, smiled and said, "Did you ever tease ants with blades of grass when you were young?" ”

Listening to this suddenly changed question, I couldn't guess Nangong's intention for a while, so I had to nod my head to see what he was going to say next.

Nangong smiled and said: "My favorite thing to do when I was a child was to tease ants with branches, I would put the branch in front of the ant to let it climb up on its own, and then lift the branch into the air and watch the ant walk back and forth on the branch." But no matter how long it walks, it can't get back to the surface. ”

I listened to her words, and I thought about the ants crawling back and forth on the branches of the tree but never returning to the ground, but my heart was cold. If we don't care about what is holding us in this cycle now, then the problem we face is much simpler. It's a never-ending journey, and unless the guy with the branch is willing to let us down, we'll end up trapped in the branch like the ant.

Nangong laughed miserably, as if he knew what I was thinking, and said: "That's right, we are now ants in the hands of this invisible force, if it doesn't want to let us out, we can only keep shuttling back and forth in these stone chambers, and we will never find the exit." ”

I took a deep breath, relaxed my tense spirit, thought for a while and said to Nangong: "Perhaps, we can jump out of this branch and return to the ground." Think about it, if an ant on a branch accidentally falls off a branch, it will return to the ground and be free. As long as the two of us can know how to escape from these stone chambers, then we can return to the main burial chamber or the cave again, and then we can get out of this cycle of death. ”

Nangong looked at me and said, "Then how can I get rid of this stone room?" Are we going to open another exit from here? It's all slabs of stone, are we going to make a hole in the stone wall with a sapper's shovel? ”

I fell silent, sat aside and stopped talking, even though I knew that this was indeed a dead loop, we still had no way to find a way out, and instead lost the motivation to go on.

Nangong also sat down, but she was squatting on the side and drawing something, I was disheartened now, and I didn't care about her but sat down directly and began to rest, in a daze, I fell asleep again.

When I woke up again, Nangong was still squatting there writing and drawing, which made me start to worry, thinking of my inexplicable anger before, I suddenly felt a chill in my heart, ran over and hugged Nangong's shoulder, and yelled at her.

Nangong was taken aback by me, looked at me a little inexplicably and said, "What are you crazy about?" ”

When I saw that she didn't look like something was wrong, I finally put my mind at ease and said to her, "What are you painting here?" I thought you were crazy. ”

Nangong's head lowered again, and then drew her picture and ignored me. I didn't bother her anymore when I saw that she was so serious, and looked down to see what she was drawing. She drew a polyhedral shape, and I really can't count how many facets there were, and she wrote a lot of formulas with letters as she drew them.

To be honest, I could tell that she was writing formulas, and I was very grateful to my junior high school math teacher, but I couldn't understand what those formulas meant. After a long while, Nangong finally stopped, but his brows furrowed even deeper.

Seeing this, I asked, "What are you doing with so many numbers written like a ghost?" Are you calculating where that wormhole is? ”

Nangong pursed his lips, looked at me dissatisfied, and said, "Maybe there is no parallel space here at all, let alone a wormhole, all of these are the tricks used by the ancients to cover our eyes." ”

Actually, I don't particularly believe in parallel spaces and wormholes, but when we encounter something completely incomprehensible, we will put a scientific name and head on ourselves, and then use things that we can't understand at all to explain those phenomena. In fact, this is no different from the ancient people who hung those incomprehensible things on ghosts and gods, they are all superstitions in disguise, but the objects of superstition are different.

But I couldn't understand what Nangong painted at all, so I had to ask her directly, "Do you know the secret here?" ”

Nangong nodded and said, "Let's ignore the scene where the two of us come in first, and analyze the part of the stone room first." You said there were sixty-four of these stone chambers, right? ”

I nodded and said, "All of them are counted, and if I count correctly, it should be sixty-four." ”

Nangong nodded, and then said: "We always thought that we walked in a straight line through the stone chambers, so when we returned to our original position, we thought that this place was endless, but in fact, there is such a way to achieve this effect. ”

Pointing to the things she had drawn, she continued, "You see it's a sixty-quadrilateral, and each side represents a stone chamber, so when we pass through the sixty-three chambers, we'll go back to the original one." Whereas, the inner angle of the hexagon is close to one hundred and seventy-five degrees, which is close to a straight line. In addition, we all entered another stone chamber through a stone door, so we could not detect that this stone chamber actually had a small angular deviation, and after sixty-four superimpositions, these deviations would form a circle of 360 degrees and return us to the original point. ”

I didn't understand Nangong's words too much, but I could understand what she meant when combined with the picture she drew. These chambers are not in a straight line, but form a circle and are connected end to end. We are like rats in a toroidal glass tube, moving forward meaninglessly, but there is no way out.

Nangong's explanation brought us back into reality, and thinking that there was no supernatural force here, I suddenly began to have confidence in going out. Now we can get out of these stone chambers as long as we can find the mechanism to get out. It's like the rat can only come out if the plug on the ring glass tube is opened, all we have to do is open the plug ourselves.

However, I suddenly thought of the cigarette butt thing, and Nangong's statement could explain almost all the problems. But what she didn't know was the cigarette butt thing I had experienced. My heart suddenly became heavy, and looking at Nangong, who had rekindled her self-confidence, I didn't know for a while whether to tell her about it.

While I was struggling, the sound of a mechanism activating began to appear in the stone walls of this stone chamber, and it felt so familiar. Just as Nangong and I stood up, countless holes appeared in the walls around us, and then a buzzing sound came.
