After the old prostitute was awakened, she stood up instantly, thinking that she had heard something unusual, so she hurriedly took out the guy and looked around.

But if you listen carefully, it is a beep sound generated by electrons, and when you follow the sound, it turns out that the watch on Xiao Yu's hand is ringing. Only then did I realize that my reaction was a little too nervous, and I immediately relaxed.

Xiao Yu also woke up and was looking at the watch on his wrist in amazement.

"How long did we sleep and when did you set the alarm?" The old prostitute looked at Xiao Yu and asked.

"It's not an alarm clock, it's an alert."

The old prostitute looked dazed, and asked suspiciously: "Alert, what alert?" Does your watch also have a warning of danger? ”

Xiao Yu immediately stood up, turned off the sound of his watch, and didn't want to explain more, but said, "We have to get out of here as much as possible." ”

After saying that, Xiao Yu walked towards the only passage, and the old prostitute hurriedly followed when she saw this, asking Xiao Yu what was wrong as she walked.

"My watch is not just to see the time, there are many functions, the alarm just now is oxygen monitoring, there is not enough oxygen here, so we have to get out of here quickly." Xiao Yu explained as he walked.

"Oh my god, are all the watches so advanced now? It's too much of a feature. Where did you buy this watch? I'll buy a piece when I go out. ”

"This is made in Germany, you can't buy it in China, if you go out, I'll ask someone to buy another piece and send it to you......"

Before Xiao Yu finished speaking, he stopped, and at the same time, the old prostitute also stopped, because there was no way out in front of them.

This made the two of them feel very surprised, they thought they had found a way out, but they didn't expect it to be a dead end.

"What to do? It's also a dead end. Xiao Yu looked at the old prostitute and asked.

The old prostitute did not reply immediately, but carefully checked the stone wall in front of her, and found that the stone wall blocking the way in front of her and the stone wall on both sides were one, without the slightest gap. In other words, this stone wall cannot be a mechanism.

The old prostitute thought about it for a while, and then said very suspiciously: "Damn, could it be that the two of us have walked into the passage of the turnaround again." ”

After speaking, the old prostitute began to walk back, this passage is not long, only a distance of more than ten meters, and walked back to the stone room where they were resting just now.

The two of them turned back a few times, and found that the stone chamber and passage here had not changed in the slightest, which made them feel very strange, since it was not that kind of mechanism passage, why was there no way out ahead?

At this time, Xiao Yu was a little nervous again, because his watch began to beep again.

The old prostitute deliberately glanced at Xiao Yu's watch, which looked the same as a normal electronic watch, but when she remembered the beep, there would be a small red light flashing constantly.

After Xiao Yu turned off the sound, he said to the old prostitute: "Let's blow up a way, otherwise the air here won't last long." ”

His idea coincided with the old prostitute, who liked this simple and effective method. Walking to the stone wall of the passage, the two men began to dig a blast hole, but no matter how much they used the steel cone, they could not make a blast hole.

"No, the stone here is too hard, it's completely different from the one in the passage over there. I'm afraid that the blasting won't work for the stones here, and even if you can barely put the blast YAO in it, you won't be able to blow it up much. At this rate, before we can blow up the passage, we will have to suffocate to death because there is no oxygen. Xiao Yu chiseled a few times and decided to abandon this method, thinking that blasting here would not work, and it would only be in vain.

The old prostitute tried a few times, and also felt that it was a bit unreliable to blast here, but if they didn't do it now, they couldn't think of a better way, and they couldn't go back along the original blasted passage, after all, there was already a poisonous gas pouring there, and going back would be tantamount to asking for their own ideas.

The two of them returned to the stone room, a little hesitant to go back to the original passage, the old prostitute was strongly opposed, he did not want to be festered by the poisonous gas when he was dying.

But Xiao Yu had a different idea, and he wanted to go back and try it, as long as the poison gas didn't reach the passage where they blew up, they might blow it up somewhere else.

The old prostitute felt that Xiao Yu's idea was too naïve, and the poisonous gas must have spread to the entire passage, after all, they slept in the stone room, and for such a long time, there was enough poisonous gas to penetrate the entire passage, so he insisted on opposing it.

"So what do you say? Let's just wait here to die, instead of waiting here for death, it's better to go over and gamble. Xiao Yu shouted at the old prostitute, and after shouting, he kicked the stone wall in great annoyance, and then scolded: "I don't know which bastard it is, what is the purpose of designing such a stone room with such a lack of morality." ”

The old prostitute looked at Xiao Yu and seemed to think of something, and muttered, "Yes, why are you designing such a stone room?" It can't be designed to trap the two of us. Speaking of this, the old prostitute immediately reacted, and hurriedly said: "This stone room will not be closed, there must be a mechanism." ”

After the old prostitute finished speaking, the two of them began to inspect the surrounding stone walls, and Xiao Yu asked very puzzled while looking for a mechanism: "How do you know that there must be a mechanism?" Is there any basis for this? ”

"Do you think it's a natural occurrence?" The old prostitute asked.

"I'm cāo, is this showing off your IQ? Fools know that this place can't be natural. ”

"Oh my god, then you fucking ask me, since this place is not naturally formed, it is artificially excavated."

After the old prostitute finished speaking, she paused, seemed to feel a little hypoxia, and then lowered her voice a lot, and then said: "On the surface, this is a dead end, and there is no connection with the outside world, but have you ever thought about how this place is not connected to the outside world, how did that person come in and dig this stone room, and this stone room was never created to trap you and me, and its existence must have a certain significance." ”

"What's the point?" Xiao Yu asked.

"Oh my god, I don't know what it means. Hurry up and find it, I'm fucking struggling. ”

After the two of them searched all the stone walls, they didn't find any special places, with the experience of the old prostitute, if there is a mechanism here, even if it is hidden in a very hidden place, as long as they look for it with their hearts, they will definitely be able to find it, which the old prostitute is very confident.

But ten minutes passed, and the oxygen here was almost zero, and the results of the search were very disappointing to them.

The two of them began to feel a little depressed and helpless, and they also began to show fatigue. The two of them sat down, you look at me, I look at you, and there was not a word of exchange.

The old prostitute had begun to feel dizzy, but he was still trying to wake himself up and didn't dare to let himself sleep. And from time to time, he also dragged Xiao Yu to remind him to persevere.
