Everyone saw that on each side of the large square lattice were drawn three parallel small lattices, connected by straight lines. Nangong Yu, www.biquge.info pen fun pavilion, explained: "This big lattice is a 'windmill', it will turn, and as long as it turns for a week, three new burial chambers will emerge. The burial chamber where we marked yesterday has been transferred, so there is no sign in the burial chamber today. After hearing this, everyone suddenly realized, and said charmingly: "It seems that this is really the case, how did you come up with it?" Nangong Yu said: "Although the things in the tomb are exactly the same, there are no clues." But if you look closely, there are still some details to follow. ”

Lao Zhangtou smiled: "I have to listen to this, there is anything else I haven't found." Nangong Yu said with a smile: "My master said that the advantages and disadvantages can be transformed. In the same way, the exact same thing in the eight burial chambers seems to have no clue, but they are actually clues. All the burial chambers only have coffins and utensils, have you noticed that they are all firmly sealed on the ground by molten iron? Why do they do this? Why can't they be moved? The only explanation is that they have a reason why they can't move, and that's 'windmills'. Because the windmill rotates, if it is not sealed, when the windmill turns to the other side, the contents will stagger and the trick will not be played. ”

Lao Zhangtou patted him on the shoulder with a laugh, and said with a smile: "Yes, young man, are you interested in entering our business of touching gold?" Nangong Yu smiled and said, "Although we know the principle now, there is still a problem that is not clear. First, how does the windmill rotate, whether it rotates automatically, or whether there is a mechanism that can be activated. Tan Mian said: "There is no manpower here, how can it rotate automatically?" Nangong Yu said: "Rotation does not have to rely on manpower, it can also be done with the help of natural forces, the Western Regions are full of underground rivers and moving quicksand, if you make good use of it, you will start the windmill." Lao Zhangtou said: "This is easy to do, we can divide it into three ways to squat and observe, if we find that the tomb has changed, we will enter the tomb at the same time to search, so that as long as it turns for a week, that is, four times, we will definitely find a way out." ”

After coming up with a solution, everyone was in good spirits and gave birth to hope. The next day, they divided into three groups and observed the three burial chambers in the back, but after waiting for a day, everyone was crowded in the stone passage with a sore back, but the stone passage and the burial chamber remained unchanged. Lao Zhangtou said: "It seems that the windmill can't start automatically, even if it can start automatically, if it doesn't turn once in a few days, our food can't be supported by water for so long, is it possible that the mechanism is activated?" Xiao Zhang said: "We searched all the tombs and didn't find any organs." Everyone was silent for a long time, and they couldn't think of why. Nangong Yu said: "Things that are used to are often ignored, everyone thinks about what we have to touch in each tomb." Everyone's faces changed, and the old man said, "Slate mechanism!" Nangong Yu nodded and said: "In retrospect, when the slate mechanism was activated or turned off at the beginning, there would be a 'squeak' sound from the depths of the stone path, which should be the sound of the windmill turning, but the sound was very small, so I mistakenly thought it was a mouse." But we've been here for a few days, and we haven't seen a single mouse. ”

The crowd fell silent, and they all felt that he had a point. Although Nangong Yu lost his martial arts, his intelligence was superior, and at this time he faintly became the leader of these martial arts masters. Lao Zhangtou and Xiao Zhang's ancient tombs are certainly rich in experience, but when they encounter complicated situations that they have never encountered, their imagination is not as rich as Nangong Yu.

Nangong Yu continued: "I think that the mechanism that is opened is the stone slab mechanism of the three-story tomb where we are located, and the stone slabs of the last three rows of tombs have no mechanism, they are only part of the windmill, otherwise we drilled up and down in the last three layers the day before yesterday, and if the mechanism is activated, we will be transferred to the other side of the windmill, but it didn't happen, so we can deny the existence of the mechanism." The windmill is opened by opening or closing the slate, and the 'squeak' we hear happens after that. The charm sneered, "Little prodigy, tell me how we should get out of here." ”

Nangong Yu said: "First of all, I want to prove that my theory is correct, please ask Brother Zhang to come with me, the two of us are enough." Xiao Zhang said: "Okay." Nangong Yu climbed into the stone path first, followed by Xiao Zhang. Nangong Yu asked him to control the slate mechanism, and climbed into the depths by himself to personally verify whether the windmill would start. He first climbed all the way to the end of the stone road, carved the word "Nangong" on the wall as a mark, and then retreated backwards, and when he retreated far enough, he lit a fire fold. This was the code that he and Xiao Zhang echoed from afar, and Xiao Zhang immediately closed the slate.

There was silence in the stone tunnel, and after a while, there was a "squeak" sound, like the sound of the mechanism being activated, and there was a "silky" friction sound in it. Suddenly, Nangong Yu's eyes flickered, as if in the blink of an eye, and the sound had stopped. Nangong Yu thought to herself, this is the end, no, it's too fast. He hurried to the end, and saw that the wall where the mark had been carved was empty, and he was shocked that the windmill had completed the transformation of space in an instant, and barely made any sound.

Nangong Yu believes that the "windmill" is quadrangular and carries three burial chambers on each side, that is, a total of twelve. According to this theory, as long as you turn for another three weeks, the mark you just left will appear. So he asked Xiao Zhang to activate the mechanism three more times, and sure enough, the word "Nangong" engraved just now appeared again. Nangong Yu breathed a sigh of relief, and she had a bottom in her heart. Then he asked Xiao Zhang to keep the stone slabs on the lower layer of the stone path unclosed, and then activate the stone slabs on the upper level, but the 'windmill' mechanism did not move. The final conclusion was that while each of the slabs in the first three chambers could start a windmill, the premise was that the other slabs were closed. He went back to the tomb and explained the situation, and concluded: "The way to leave this ghost place now is to investigate layer by layer, first try the lower levels on all sides of the 'windmill'. If there is no exit, try the middle layer again, and so on, and you will definitely find the exit within 12 times. ”

Everyone was overjoyed, and although they were tired from the day, they all came to their senses at this time, and they all wanted to leave this oppressive labyrinth as soon as possible. They said they would do it, first try it from the lower level, Nangong Yu led the way, Xiao Zhang manipulated the mechanism, every time they turned, they went to the lower tomb to check, although there was no way out, but in one of the rooms saw Tarip's body, proving the feasibility of the method. They then moved on to the middle level, and after four rounds, all the stone gates were still sealed. Finally, there are the three chambers on the upper floor, and at this time everyone's hearts have been hanging in the air, and the closer they get to hope, the more they are afraid of disappointment, especially when after three rounds, only the last tomb remains, and they dare not imagine what to do if this is not the way out. They've been trapped long enough that they'd go crazy any longer.

As a result, it is still the door of death. He Tongguang, who lost his mind, frantically pounded on the stone door, and suddenly cried loudly. Nangong Yu touched her chin without saying a word, thinking about where the problem was. All eyes were on him, including Lao Zhangtou.

After a long time, Nangong Yu muttered: "There is only one explanation, this 'windmill' mechanism is not dead, but alive. Everyone couldn't understand, Xiao Zhang said: "Little brother is talking about 'ghosts hitting the wall'?" Nangong Yu shook his head, but did not speak, suddenly moved, took out the dagger and came to the tomb door and stabbed it hard, only stabbed a small pit, he kept drilling into the small pit, and after a quarter of an hour, he only drilled a small pit as deep as a fingernail, and then he heard a "ding" sound, and touched something metal. Nangong Yu drilled elsewhere and also touched the metal.
