Looking at the vibration of the water in the water bottle, we knew that we had returned to the space we were in.

San'er didn't take much rest, but stood up, asked Scar for a long rope, and told us to wait here, and he ran towards the back of the passage.

I don't know what he's up to, but I'm sure he's trying to do another experiment.

San'er ran very fast, and the rope moved quickly on the ground like a flying snake on the grass.

It took about twenty seconds for the rope to stop.

At this moment, I had sat up from the ground and looked in the direction of San'er's run, but I couldn't see his flashlight clearly.

Fortunately, the rope we brought was measured, and the rope that Scar took for San'er was a 200-meter outdoor climbing rope, which was very thin and light, but very strong and wear-resistant.

I took a closer look, and San'er pulled out 169 meters, that is, he is now 169 meters away from us.

After reading the rope, I asked the old prostitute and Scar what they saw before they ran back? Why did you run so suddenly?

The two of them replied in unison: I didn't see anything, I just heard San'er shouting to run, so I ran back, as for what was happening in front of them, they didn't pay attention to it at all, and just ran away with their lives.

I glanced at the old prostitute and said in my heart: Scar has never seen the world, and it is understandable to run for his life as soon as he encounters an accident. But your old prostitute is a person who has experienced strong winds and waves, how can you run away without figuring out anything like Scar, it's a fucking shame.

I was thinking about it, so I couldn't help but shake my head, and the old prostitute just happened to see me shaking her head, as if she could see what I was thinking. immediately scolded at Scar: "Damn, you kid didn't see anything, and you ran fucking with your life." I thought you saw something, or Lao Tzu wouldn't have followed you. ”

"It's not that I'm going to run, didn't I say that I listened to that San'er, he shouted to run, and I ran away." Scar explained helplessly.

The three of us, you and he discussed for a while, all guessing what San'er saw in front of him. I guessed everything I had seen and never seen, and even what I couldn't hit with eight poles was told by Scar.

"Don't guess, there's nothing." San'er said.

We were still guessing before San'er came back, and when we saw him, he was less than twenty meters away from us.

"No, there's nothing, so what are we going to run?" Scar asked, surprised.

"If you don't run, you'll never come back."

"What do you mean?" Scar was puzzled.

San'er didn't rush to explain, but lowered his head to look at the meters of the rope, and then drew with his hands on the ground, as if he was writing something.

Scar wanted to continue asking, but I stopped him. I don't know what San'er drew on the ground, but I saw that he was very focused, so I didn't let Scar ask again.

When I walked over to take a look, I realized that San'er had just done a simple division problem on the ground. However, the number he wrote was very unclear, and he could only see that it was divided by 2, and the specific number could not be read clearly.

Looking at the division problem written by San'er, I suddenly felt that this guy must not be very good at math, and he may not even have gone to elementary school, otherwise a simple problem of dividing by 2 would still need to be written on the ground to calculate.

After finishing the calculation, San'er stood up and said to Scar, "That passage is a trap used to trap people. ”

I don't know if I saw the old prostitute and Scar, but the moment I ran backwards, I looked inside, and it was indeed a dead end. When I guessed what would be in there just now, I didn't even think about the dead end, I always thought that San'er saw something, so I shouted to run back, so I didn't think about the trap that trapped people at all.

Now that I think about it, it really looks like a trap for people. I nodded, looked at San'er and said, "Fortunately, you made a decisive decision at that time, if you delay for a few more seconds, then we will be trapped inside." ”

"If you're thanking me, don't thank me, you should be thanking the people who built the passage, they didn't build it long enough so we had time to run back."

I savored what San'er said, and it really made sense. Although I didn't mean to thank him for what I just said, what he said was true. If that passage had been a little longer, we wouldn't have been able to run back if we had walked forward for a dozen more seconds. I'm afraid that by then, the passage here has already been turned, and we are really trapped inside.

"How do you see that?" The old prostitute asked San'er.

"Intuition," San'er said, walking towards the edge that was still slowly turning.

"Oh my god, you made a decision based on intuition...... "The old prostitute was about to say something, but I interrupted her. I know that what this guy is going to say later is definitely not a nice thing, it is probably either sarcasm, sarcasm, or overturning San'er's intuitive remarks.

I told the old prostitute about the situation when I ran back and saw a dead end in front of me, and he was also thoughtful after listening to it, although he didn't fully agree that San'er's decision was right, but he didn't say anything unpleasant.

Actually, I don't really believe in intuition, of course, I do believe it once or twice once or twice, but the facts are there, one thing is certain, here it turns, and it continues. Then it means that the back road of that passage has been blocked.

I looked at San'er standing on the edge of the rotating stone wall, he kept looking at the still rotating stone wall, his expression was different from before, it felt a little weird, after a while, he spoke, and said lightly: "It seems to be round." ”

"What is round?" I couldn't help but ask.

San'er touched the stone wall with his hand, and his eyes swept around the colored stone passage, before looking at me and replied, "This rotating space." ”

"You're saying that the rotating space we're in now is circular?"

San'er nodded, and I continued: "If it's round, it's easy to do. ”

"Easy?" San'er repeated what I said in confusion, and then said, "Do you know how big this circle is? ”

"If I'm not mistaken, you just ran out to see the rotation at the other end of the passage, and this distance should be 169 meters."

San'er signaled that I was right, and I continued: "169 meters, it seems that the diameter of this circle is indeed very long, but no matter how big this circle is, as long as it is round, as long as it turns in one direction, there will always be a time to turn around. We can mark the opening of each turned channel, for example, the next channel that is about to turn out, we mark it as 1, then the next channel as 2, and so on, until the circle turns into a circle, and then turns back to 1, we can grasp the rotation law here, and deduce which is the original channel when we come in. ”

I thought that after I said this, San'er would look at me differently, but unexpectedly, he showed a bitter smile coldly, and said in a low voice: "It seems that you haven't experienced enough, don't think about this, sit down and rest for a while." ”

After San'er finished speaking, he leaned against the stone wall and sat down, closing his eyes and resting.

When I saw that he didn't want to speak, I didn't say anything more. I began to think about what he said, and I didn't understand the meaning of his words at all, but I just thought it was a little weird, but I didn't understand whether he approved of my plan or didn't agree with me.

I didn't understand what he meant, but the way he sat and closed his eyes made me feel sad. Because the way he sits is so similar to the little wolf, it looks like it was carved out of a mold, and if I were to cover his face, I would definitely think that he is the little wolf. So seeing his posture at the moment, I instantly thought of the little wolf inside, and I don't know if he still has the strength to sit like San'er at this time.

After about a minute, I finally turned to another passage, which was still a colored stone passage.

After the rotation stopped, I took a closer look at the docking of the two colored stone passages, as if it was a seamless docking, and there were very few traces left at the link, if we didn't know the location of the docking in advance, I'm afraid it would not be easy to find this docking point.

"Do we want to go into this passage?" Scar asked.

"Come in your sister, go in, I know that the direction is wrong, and I still get a fart." The old prostitute choked Scar quietly.

I walked out of the docking point more than two meters away, carved a very conspicuous 1 with iron on the stone wall, and then walked back to the rotating space.

The old prostitute kept watching my every move, and when she saw me walking back, she asked me, "Even if you turn around every passage, are you sure which one is right?" ”

"As long as I can turn around, then I will be able to figure out which passage we will come in." I replied confidently.

"The difficulty is not in the calculation, but in how to make it turn again." San'er's sudden interjection made me chuckle in my heart.

I began to understand why he was talking to me just now, it turned out that he had thought of these things for a long time, but there was still a question that bothered him, but I didn't think about it. That's how to make this rotating space rotate again.

"It's really hard." I thought for a moment and said, "It's a little harder, but we can still try, maybe not as hard as we imagined." ”

"Tell me what you think." San'er asked.

"If you want this place to turn, you have to understand the mechanism of this turning. Almost all of the ancient organs were the same, and they never deviated from their origins. In my opinion, it's very likely that the mechanism here is triggered by gravity. From the first time we walked into this mechanism, it turned, it must have been that we increased the gravity here to trigger the mechanism, and then when we walked into that trapped passage, it also rotated, and that was because we went out and reduced the gravity that we had increased, so that the gravity here came back to square one, so it started to rotate again. This is enough to prove that gravity is the trigger point for turning the trap. In other words, every time gravity is added and returned to the original gravity, a trap rotation will be triggered. ”

I saw that none of them had an opinion, and continued: "If we change the gravity here, we can make this place turn." In fact, it is very simple to change gravity, we just need to get out of the rotation space and let the gravity here return to the original gravity again, and we can trigger a mechanism rotation. ”

"Although what you said makes sense, I think you are oversimplifying, maybe it has something to do with your past experience, and the mechanism here will not be as simple as you think." San'er said to me.
