"Let's go, let's go through it again and see where we're taking a detour."

After finishing speaking, Li Wu waved his hand, asked the fat man to follow him, found an entrance casually, and walked into the gossip array like an endless loop.

"Wuzi, I don't feel like there's a turn, haven't we been walking in a straight line?" just now the fat man was staring at the ground all the way, walking forty or fifty steps, and he didn't feel that he had a turn when.

"Fat man, you take out the rope of the bag, let's do an experiment and know" Li Wu thought for a while and said, in fact, he didn't hurry to get there There is a bend, because the stone pile is not connected into a wall, there is a gap in the middle, so even if there is a bend, Li Wu and they can't detect it.

"How?" asked the fat man, pulling the rope out of his backpack.

"You put this end of the rope on this pile of stones and don't move, I put the other end on the stones in front of me, you should be able to see if it is a straight line" Li Wu said the method to the fat man, pulled the end of the rope, and walked forward.

"We're really taking a detour" The fat man looked at the pile of stones that were straightened by the rope, and the piles of stones between the two of them obviously did not touch the rope, that is, these piles of stones were amplitude, not straight forward.

"Fatty, now you go forward, let's use the rope to measure all the way over, to see where the amplitude is larger, the exit is estimated to be there" Li Wu The rope they bought was a ten-meter climbing rope, such a distance was just enough for them to effectively see which stone piles had a large amplitude.

"How much is this, are you sure this method works?" The two switched back and forth seven or eight times, and the fat man didn't notice that there was a large arc, and he couldn't help but wonder if Li Wu's method was feasible.

"Where is this, you are in a hurry, hurry up, walk ahead" Li Wuzhen was angry with the fat man, and he had just begun to measure, and he began to doubt.

"And don't look at the rope, but also pay attention to the distance between the two stone piles, if there is a relatively large one, maybe it is the exit" Li Wu thought for a while, and then explained to the fat man.

"Wuzi, come and see, this distance is very big, do you think it will be an exit?" As soon as Li Wu's words were finished, the fat man said loudly.

"I don't know, but I finally found another way, let's go, let's go and try it" Li Wu waved his hand a little excitedly, although there was no big turn here, and I wasn't sure if it was an exit, but Li Wu was still very happy to be able to leave the established track of this gossip array.

"Okay, then I'll go ahead, if I can get through, you'll be able to pass," the fat man said, and took the lead in getting through the crack in the rock.

"Wuzi, this road is getting wider and wider, are we looking for the right way, and you see this rope, all of them are attached to the stone pile, we are walking in a straight line" When the fat man first entered this road, it was still a little crowded, and now after walking for ten years, it found that the road is getting wider and wider, and there is no difference from the one when they first came.

"Maybe, I don't know," Li Wu said with a frown, he always felt that he had overlooked something.

............

"Wuzi, is this the way out? We didn't walk for so long when we came in, and look at these stone piles, how do I feel so familiar! We won't go back to the original place, right?" After walking for about twenty minutes, looking at the familiar scene around him, the fat man shouted incredulously.

"This is not where we just stayed, see if you can find the mark you left behind. Li Wu said noncommittally.

"Not really, but why is this place so similar to somewhere? Is there two places in the same place?" the fat man looked around in confusion.

"Hey... I think you're right, there are indeed two places in this Bagua Array" Li Wu sighed and said: "I just said that we were in the center of the Bagua Array at that time, but now I think it's wrong, that position should be in the center of the Yin Fish, and now we are in the center of the Yang Fish, or switch it." ”

"Do you mean to say that there are two places in this gossip array that are the same, and the road we just walked over leads to another place? But didn't you say that you can go out after walking in a straight line for a long time? The result we just measured with a rope is to walk in a straight line!" The fat man stared at Li Wu with a confused expression.

"I've just figured out this question, the road we started to take was turning to the left, so we could measure its amplitude, but when we went to the other road, it turned to the right, and we measured the same change with the rope, and of course the rope would stick to the rocks."

"Damn... So we're in another loop?"

After listening to Li Wu's words, the fat man opened his mouth, and it took a long time to hold back a sentence.

"Hehe, so to speak!" Li Wu smiled when he heard this.

"You can still laugh, forget it, I'm really not leaving, it should be twelve o'clock now, I'm too hungry to walk, I think I'd better wait for rescue" The fat man sat on the ground and said weakly.

"Come on, don't think about rescue, Professor Wang, they will come to us as soon as they arrive, but when do you think they will come here, it is estimated that they will not arrive tomorrow at the earliest, do you want to spend the night here?" Li Wu kicked the fat man with his foot, and then said: "Although we have arrived in another formation, but we have finally found another way, this proves that my method is still feasible." ”

"Then let's go one last time, if I can't find the exit, I'm going to really have to spend the night here" The fat man sighed, in fact, if he was really tired and couldn't walk, there was no, but the real road of this gossip array seemed to have no end, and he was a little flustered.

"Okay, then go one last time, by the way, you turn off your lights first and turn them on, otherwise if there is no electricity, we will be finished" Seeing the fat man's strong light shining on his face, Li Wu thought of saving power supply, although the strong lights they bought can be illuminated for more than ten hours in a row, but who knows how long they will stay here, it is better to save some electricity.

"Okay, then mine is off, you follow me, but what do you say we should go back this time" The fat man also knew the importance of the light, and after listening to Li Wu's words, he turned off the light casually, and pointed to the road when they just came.

"It's okay, it's the same if you go that way" Li Wu nodded indifferently.

............

"Did we just come out of here?" After walking in the same way for another twenty minutes or so, the fat man finally found another intersection that he could pass.

"Judging by the distance, it should be, but I'm not sure, let's go in and have a look," Li Wu shook his head and said.

"Wuzi, how do I feel that it is the road I just walked, don't you feel that the road is getting narrower and narrower" The fat man felt that now this road could only let him just walk.

"No matter, let's go over first"

Li Wu also noticed that the road had narrowed, but he had already arrived here, so he could only continue to move forward.

"It's finally getting wider, just almost... Damn, Wuzi, can you take a snapshot of it, is it a palace" The fat man walked and walked, just felt that the road had become wider, and suddenly seemed to see a palace in front of him, but now he put the strong light in his bag, and he couldn't see it clearly.

"This is the Eunuch Bureau, thank goodness we finally came out"

Li Wu saw the eunuch in front of him and said with feeling.
