The winner threw down the folding shovel in his hand stupidly, very depressed. "I think the principle of gravity should be used here, using some strong springs or something, as soon as a person steps on it, the gravity on both sides of this tomb is different, and you can immediately lift this passage up, very old lever design. I've seen it in a Shang Dynasty mausoleum before, but it's far from being that big, and I don't really know how to design it. Yao Jiuyin said with some sighs.

"Wow, senior brother, you still know gravity, I really admire you! I said loudly.

"Cut, don't you know that I also went abroad to study, unlike some self-righteous professors, who have a vain name......" Yao Jiuyin glanced at Ying Ziling a few times intentionally or unintentionally. I said Yao Jiuye, you said so much, how are we going to go down? Win Ziling suddenly said. It's simple, as long as you can find the pivot point of that leverage. In fact, I can conclude that this passage has been moving up and down all the time, but the amplitude is so small that we can't feel it. Yao Jiuyin seems to have suffered the loss of this design, and he is also very familiar with this principle, and he found a small nylon rope in the package. Ah Meng, you hold the rope and keep walking here, wait and pay attention to the horizontal line of this nylon rope, if there is a tilt, run back at speed! Do you understand? Ying Ziling was a little puzzled, this Yao Jiuyin said the same as the Book of Heaven, in fact, he didn't understand it very well, so he simply didn't ask. He grabbed the end of the rope and walked forward for about ten minutes, but he didn't see any strange signs. At this time, he seemed to hear Yao Jiuyin's shout, and Ying Ziling looked back, and immediately dispersed. He didn't know when this nylon rope was already tilting downward at an inverted forty-five degree angle, which means that Yao Jiuyin and they were sinking now! Thinking that he might be left alone in this tomb, Ying Ziling had only one thought in his head: run!

However, when the winner ran back breathlessly, he found that the rope in his hand had gradually become parallel to the ground again. Ying Ziling's face turned a little pale, and they hurriedly asked out loud when they looked at Yao Jiuyin. "Uncle Cripple, did you sink here just now?" "Well, it's a tiny feeling, and if it weren't for seeing the nylon rope tilt, we wouldn't even know the slate was sinking." Yao Jiuyin said. "Do you remember that place, Ah Meng? The position you step on is the fulcrum of that lever. "Remember, but how to step on it, if one person steps on it, how can that person come down?" Thinking of the scene that happened just now, Ying Ziling couldn't help but feel a creepy feeling. Yao Jiuyin frowned, he also had a little headache, this was really a problem. It takes a certain amount of weight to support it, and this stone slab can be gradually put down, but here is a bare piece, and there is nothing to hold that fulcrum! They tried back and forth several times, but they couldn't succeed, and as soon as someone left the fulcrum, the slab would slowly rise up and come back here. It also means that if they want to get out of here, they have to have someone to die. They wanted to put the contents of the package on the fulcrum, but found that the weight of the package was not enough to reach the strength required for the fulcrum. When they came, they had already thrown away all the unused things in their backpacks, and now the package didn't even weigh sixty or seventy pounds. The silence of the four people is as deathly, no one speaks, and when faced with this choice, it is too cruel, and no one will want to choose a dead end.

The silence of the four people is as deathly, no one speaks, and when faced with this choice, it is too cruel, and no one will want to choose a dead end. "I have a solution, maybe I can try." Ying Ziling thought about it, and said with some hesitation, and suddenly Yao Jiuyin's eyes lit up, and they all looked at Ying Ziling. "There is no doubt that the terrain here is very deep, and I just found out that there should be groundwater around this ring road. I think the smell here is very humid, don't we have some oil or something? As long as a fire is lit there, the hot air and the humidity here are mixed, and a large amount of water vapor should be formed, and when the time comes, it should be enough to absorb the stone and soil, and the weight should be enough......" Ying Ziling stared at a few people a little hairy, this method was idle and boring to see in the chemical magazine, but he didn't expect to use it now. "Don't stare at me, I'm just guessing, I don't know if it can be done." Ying Ziling hurriedly shouted. "It sounds like there is a bit of a feasible Cheng dù, if not, I'll open the way for you with this old bone. Haha, the little matchmaker has been waiting for me for more than ten years, and I should go to her too! The sick ghost said with a smile, looking indescribably lonely. Over the years, he has been following the instructions of the little matchmaker to him that night: "Live well." "He seemed to be relieved at once after making this decision." Uncle Ghost, don't talk nonsense, we will definitely be able to get out! "Ying Ziling looked at the lonely appearance of the sick ghost, and his mood was indescribably sour, all these years, the sick ghost has been very indifferent, who can know the pain in his heart?" Hehe, silly boy. The happiest thing I've done for so many years is to grow up with you, a cute boy......" The sick ghost looked at Ying Ziling and began to cry uncomfortably, and he couldn't help but feel relieved, he touched Ying Ziling's little head and laughed loudly. "That's what you said, we'll be able to get out!" A few people walked back to the direction of the fulcrum, and the sick man took out a bottle of fire oil and a large bottle of gasoline from his bag, which was originally intended to be used for self-defense, but he did not expect that it was now used for artificial rainfall. "Ah Meng, how do you get gasoline?" Yao Jiuyin is not good at this thing, he set his eyes on Ying Ziling. Ying Ziling squinted his eyes, racking his brains to think about what that book said, but fortunately, his memory was not bad, and he was reminiscing at this time. "Uncle Cripple, you scatter this gasoline separately, be wider, and most importantly, have a large range. And this fire can't burn for too long, as soon as the heat goes up, the moisture will condense into water drips down, if the fire burns for too long, I'm afraid the water droplets will evaporate! "Uncle Cripple and Uncle Ghost, you two go back to that place first and wait for us, and as soon as the fire starts, we will run back to meet you." The sick ghost and Yao Jiuyin thought about it and nodded, after all, their health was not convenient, and it was very likely that it would be too late to run back when the time came. Zhao San's face was slightly calm, and he didn't know what he was thinking. "Third uncle, let's spread this gasoline, try to hurry up, don't let this gasoline seep down!" Counting the time when the sick ghosts were leaving, Ying Ziling hurriedly said. At this time, he was going to have to do something that was at stake in his life, and he couldn't help but get nervous. "Hmm!" Suddenly, Ying Ziling quickly picked up the gasoline barrel and gently poured it on the stone slab, while Zhao San also poured out the fire oil separately. Seeing that it was almost over, Ying Ziling was about to rub the fire fold, but he pinched it for Zhao San, and Zhao San pointed to the fire hammer in his hand. The winner nodded knowingly, and lit the gasoline with a firecracker, so that they could buy a little more time to run back. In fact, the slate is almost a hundred meters away from here, whether he can arrive before the slate is lowered, Win Ziling has no bottom in his heart. "Bang!" A large yellow flame immediately enveloped the entire passage, but the gasoline was only a thin layer, so the fire was extinguished as quickly as possible, and suddenly a huge drop of water 'snapped' on the stone slab. "It worked!" Ying Ziling was so excited that he almost jumped up, and he spread his feet like Zhao San and ran back. When Ying Ziling ran to the predetermined location out of breath, he found that the stone slab had dropped by nearly fifty centimeters, and he and Zhao San hurriedly jumped down. "Ah Meng is good!" Yao Jiuyin gave a rare compliment to Ying Ziling, and the sick ghost smiled and didn't speak, and gave him a thumbs up. "Oh, I'm ashamed, I'm ashamed." finally did an earth-shattering event in front of these old-timers, and Ying Ziling felt that he would have another topic to talk about calves in the future. "No wonder we didn't react at all just now, the colors of the walls on these two sides are too similar, and who would have thought that this hundred-meter-long passage under our feet would actually rise slowly." Yao Jiuyin couldn't help but sigh. (To be continued.) )
