San'er looked at the old prostitute and said, "Before you leave here, should you leave the things in your pocket?"

When I heard San'er say this, I immediately looked at the old prostitute. The old prostitute just looked at me and immediately stopped looking at me. As soon as I saw that the old prostitute was deliberately dodging, I said in my heart, it's over, this guy must not have done anything good, maybe he took something that shouldn't be taken.

The old prostitute pretended not to hear San'er's words, and shouted: Let's go, there are still more than a dozen people waiting to be saved, don't waste time here.

San'er saw that the old prostitute was pretending to be confused, and immediately walked towards the old prostitute. I don't see that things are good, if this fucking third son goes to the old prostitute's pocket, then he has to do it. I hurriedly ran to the old prostitute and asked him softly, "Did you take something?"

The old prostitute stared at San'er, and said to me in a low voice: "Take it, I saw that the porcelain pine was in good condition, so I took one of them."

"Are you fucking crazy, didn't you say, you can't take the things out here, put them back quickly."

"Why can't you take it out, if you don't say it, if I don't say it, who will know where this thing came from."

After the old prostitute finished speaking, I urged him again: "Hurry up and put it back, this thing is worthless, don't forget what we are here for."

"Do you think Lao Tzu is for money? I'm fucking for you and Zhanzhao, with this thing in my hands, are you still worried that you can't find any truth?" The old prostitute reached out and took out a turquoise from her coat pocket and said, "Okay, I'll fuck you for this fucking extra heart, if you want to put it back, you go, I will definitely not go."

I took the turquoise in the old prostitute's hand and glanced back at San'er, meaning to tell him that I had already brought the turquoise out, but I didn't think that San'er would say: There is.

"Old prostitute, is there still one?" I asked.

"No, don't listen to his nonsense, I'll take one."

I took advantage of the old prostitute's conversation and reached into his pocket. Good guy doesn't know if he doesn't flip it, and he is scared when he flips it. There were two turquoises in the old prostitute's pocket.

"You fucking lied to me." I scolded the old prostitute, and then handed the three turquoises to San'er.

When San'er went to put the turquoise back in the coffin, the old prostitute whispered to me: "Xiaoqi, are you fucking stupid, you just take one out of your pocket, why do you take out both." If Zhanzhao was here, he would definitely agree to me taking all three out. ”

I ignored the old prostitute, packed up my things and prepared to go back.

All the way back, I didn't say a word to the old prostitute, not to blame him for stealing the turquoise, but I didn't know what to say to him. I believe him and take turquoise for the wolf and me, I don't doubt that. But one thing I'm more sure of is that this guy is a money junkie, and if he only takes a turquoise, then I'll be pretty sure he's trying to help me and the little wolf. But he took all three, which proves that he is still a little selfish.

Walking back to where we had been sucked down by the whirlpool, San'er organized us to climb up the rope he had lowered beforehand. For the sake of safety, only one person is allowed on the rope at a time, and only the first person can go up and pull the rope a few times, and the second person can go up again. This is a bit of a delay, but it's a safe bet. In fact, we mainly want to avoid problems with the rope, and we are also afraid that the rope will not be able to bear the weight of four people at the same time. After all, there is only one rope that can be put down, and if something really goes wrong, it will be difficult to go up from here.

The process of going up is not described in detail, although there is the help of the rope, but it also takes a lot of effort. Originally, the walls of the cave were very smooth when washed by water, and there was a layer of slippery scale on the surface, so the feet could not bear the strength at all, and they could only rely on the strength of their hands to climb up. When I climbed to the top, I realized that the hole could be as tall as a seven-story building.

I was the first to come up, and when I saw the scene above, I was stunned.

For a moment, I almost forgot to pull the rope, and after a few seconds, I remembered to pull the rope twice to remind the people below that I was coming up.

Everything in front of me is indescribable. At first glance, it looks like a ruin. A space the size of a basketball court is full of stones scattered by the collapse on it. There is not a single decent stone wall around this space, and there are all large and small water holes.

The situation above looked even more terrifying, with a few rocks hanging from it and crumbling, especially the passage above, and a section hanging in mid-air. I looked up and saw that the rocks were so big that any one of them would fall enough to flatten a person.

While waiting for the second person to come up, I carefully looked at the entire space and found that ten meters away from me, there was an underground river, but the river did not seem to be deep, and a fallen stone pillar was not submerged in the river.

I took a general look, and the stone pillars falling in the water were very thick, and they had to be two meters in diameter, to say the least. When I first saw it, I thought it was a bridge pier. But when I saw a giant gear disc at the base of the stone pillar, I realized that it was not just a pier for support, but also a teleportation pillar for the mechanism.

You don't have to think much to guess that the rotating space above is all driven by it.

"Can you see what makes it turn?"

I looked back, and the second one to come up was San'er, who was asking me.

"It's supposed to be water." Actually, I'm not sure, but I haven't seen anything more powerful, so I judged it to be water.

San'er nodded and said, "It's okay." ”

When I heard him say this, I didn't know whether I should be happy or angry. I am happy because my judgment has been recognized by San'er, and I am angry because there is a very reluctant element in his words.

Of course, I'm not a stingy person, and I didn't think that I had to get San'er's approval, if it wasn't for coming here to save the little wolf, I don't think I would have known him in my life.

"How do you know that the rotation up there is driven by water?" I asked.

"Presumably," San'er replied.

"Speculation? That's a bold speculation. Luckily, your speculation is correct, otherwise we would all be hanging here. ”

"It's not hard to guess this, as long as you know a little bit about this place, you will find that there is nothing else here that has such a big thrust except for the water of the underground river." San'er explained.

I thought about it for a moment and thought it made sense, after all, the space that rotated on it could weigh hundreds of tons, and only water could do it here.

"I agree that the water is driving it, but how do you know that when the water collapses, the water here will go down, and if the water level doesn't go down, then we will drown in the passage above." I said.

"When you ask that question, you still don't understand how water creates power." I motioned for San'er to continue, I really didn't understand this.

"This process is a bit complicated to explain, do you know the Liujiaxia Hydropower Station?"

"You know, it's a hydropower station like Gezhouba." I replied.

San'er was stunned for a moment when he heard me say Gezhouba, as if he didn't understand, and thought for two seconds before asking: "What Gezhouba?" ”

I was also stunned when I heard San'er ask this, and I said: He is too strange, he knows Liujiaxia, but he doesn't know Gezhouba. But when I thought about it, I didn't think it was right, maybe he hadn't built Gezhouba before he came to the ancient city, so he didn't know. Hurriedly explained: "Gezhouba is also a hydroelectric power station, you continue to talk about yours." ”

San'er continued: "Actually, the principle here is similar to that of the Liujiaxia Hydroelectric Power Station. If you want water to be more powerful, you have to store it. Although it is not as big as Liujiaxia, the water in this space is enough to drive the mechanism, and it only needs to be filled with water and quickly discharged, which will produce a huge impetus in the process of drainage. In other words, in order to control the mechanism above, it is necessary not only to have an inlet, but also to have a drain that can discharge water at any time. Can you understand what I say? ”

I nodded my head in understanding, and pointed to the hole we had just come up to and said, "This is the drain." ”

"No, not here." San'er shook his head, stretched out his hand to point to the location of the river, and said, "It's in that direction." Where the stone pillars of the mechanism are, then the driving force of the water flow will naturally be there. If it were us, it would not be possible to drive the stone pillar to turn. ”

"And how did you figure out this hole?" I asked.

San'er smiled and said, "It's a windfall. This hole should have existed for a long time, but it was by no means a drainage. Perhaps the hole was sealed before it collapsed, but unfortunately, it was smashed open by a falling stone, so we could see everything below. ”

"No wonder you didn't agree with the old prostitute blowing up the passage at that time, it turns out that you have thought of it a long time ago. But since you already thought about it at the time, why don't you tell us? I asked San'er curiously.

"If I had told you then, would you have believed it?" San'er asked rhetorically.

I thought about it, smiled, and didn't answer. If San'er said it at the time, I think I would hesitate, but the old prostitute would definitely not believe him, he didn't say it at the time, which is a good choice.

"Now we have found the mechanism that rotates the space, but this mechanism has been abolished, and it is impossible to use this mechanism to find the right passage." I said.

"Do you still think there's the right passage up there?" I didn't say a word, and San'er continued: "The passage above should be all fake, and there is no passage to them at all. ”

"You mean, we can't save the wolf?" I looked at San'er with puzzlement.

"Of course you can save it, but not by going up there, but by going in from here." San'er motioned for me to look at the other side with his eyes.

On the opposite side are large and small water holes, although it looks like there is no water inside, but when the flashlight shines through, you can still see that there are still many water droplets dripping down the hole.
