However, when Zhang Meng ran back breathlessly, he realized that the rope in his hand had gradually become parallel to the ground again.

Zhang Meng's face turned a little pale, and they hurriedly asked out loud when they looked at Chen Cripple.

"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." Chen lame said.

"Do you remember that place, Ah Meng? Nine times out of ten, 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, Zhang Meng couldn't help but feel a creepy feeling.

Chen Cripple frowned, he also had a little headache, this is 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.

"I have a solution, maybe I can try."

Zhang Meng thought about it and said with some hesitation, and suddenly Chen Cripple's eyes lit up, and they all looked at Zhang Meng.

"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 should mix together, and a large amount of water vapor should be formed, which should be enough to absorb the stone soil when the time comes......"

Zhang Meng stared at a few people a little hairy, this method was idle and boring to see in the chemical magazine, but I 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." Zhang Meng 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." ”

After making this decision, he seemed to be relieved all at once.

"Uncle Ghost, don't talk nonsense, we will definitely be able to get out!"

Zhang Meng looked at the lonely appearance of the sick ghost, and his mood was indescribably sour, over the 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 growing up with you, a cute boy......"

The sick ghost looked at Zhang Meng so uncomfortable that he began to shed tears, and he couldn't help but feel relieved, he touched Zhang Meng'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?"

Chen Cripple is not good at this thing, he set his eyes on Zhang Meng.

Zhang Meng squinted his eyes, racking his brains to think about what the book said, but fortunately, his memory was not bad, and it was a lot of memories 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 Chen Cripple nodded after thinking about it, after all, they were not physically 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 left, Zhang Meng 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, Zhang Meng quickly opened the gasoline barrel and gently poured it on the stone slab, while Zhao San also poured out the oil separately.

Seeing that it was almost over, Zhang Meng was about to rub the fire fold, but he pinched it for Zhao Sanyi, and Zhao San pointed to the fire hammer in his hand.

Zhang Meng nodded knowingly, and lit the gasoline with a firecracker, so that they could buy a little time to run back.

In fact, the slate is almost a hundred meters away from here, and whether he can arrive before the slate is lowered, Zhang Meng 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!"

Zhang Meng was so excited that he almost jumped up, and he spread his feet like Zhao San and ran back.

When Zhang Meng ran to the predetermined location out of breath, he found that the stone slab had dropped nearly fifty centimeters, and he and Zhao San hurriedly jumped down.

"Ah Meng is good!"

Chen Cripple praised Zhang Meng rarely, 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 Zhang Meng felt that he would have another topic to talk about 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." Chen Cripple couldn't help but sigh and said.
