As soon as these words came out, Chen Qingyun and Gu Le immediately glanced at each other.

Then Chen Qingyun immediately asked, "Da Zhuang, tell me quickly, how is it different?" ”

Seeing that Chen Qingyun was so excited, Niu Dazhuang knew that his discovery was likely to be the key to the disappearance of those people, so he did not hesitate, and then said: "Director Chen, every time we come down the steps, it seems that some walk long, and some walk break?" ”

Chen Qingyun and Gu Le originally thought that what Niu Dazhuang said was different, and it might be a problem with the stone steps themselves.

But I didn't expect it to be a matter of length.

Both of them were smart people, so without hesitation, they immediately returned to the top and walked down again.

They went all the way to the bottom, about five hundred steps.

Then the three of them went out together and waited outside.

At this time, no one spoke, as if knowing that the verification that was waiting for might prove all the problems.

However, after half an hour passed, Gu Le couldn't help it: "Director Chen, how long are you going to wait?" ”

Chen Qingyun said in a condensed voice: "At least an hour, or even two hours." ”

By this time it was completely dark outside.

They were in a tent, finding some resources, and clamping the miner's lamp to the tall trees around it, and the place was suddenly bright, and in this short time, they ate and filled their stomachs.

After all, in an afternoon, they don't know how many times they ran back and forth, how much time they delayed, how many questions they thought about, and how many brain cells they spent.

Strength and intelligence are both impaired.

Originally, they still refused to rest.

After all, there is no clue and progress in things, they have no intention of resting at all, and they have no intention of eating, but now, they have a little special plane and a little eyebrows, so they are a little relaxed, and when they feel hungry, they eat.

When eating, Gu Le sighed secretly, this Niu Dazhuang seems to be clumsy, but he didn't expect that he is still a key role.

If it weren't for his discovery, I'm afraid that at this moment, Chen Qingyun and they wouldn't be able to find a breakthrough.

Soon, more than an hour had passed, and Chen Qingyun felt that the time had come, so he beckoned the two of them, and the three of them took the miner's lamp and went down.

This time they were targeted, but they were not so godless and masterless, and they were also apprehensive.

But I'm still very excited, after all, the results of this investigation are so important to them.

Of the three of them, only Gu Le turned on the light to show them the way, Niu Dazhuang and Chen Qingyun were concentrating on counting the steps, step by step, these hundreds of numbers, it is really not so easy to check, if you jump down six or seven steps in a step, it won't take long to be able to go down, but when you check it like this, it's quite a lot, not to mention that they can't make mistakes.

Fortunately, people like Chen Qingyun are very cautious, and checking the numbers is simply trivial to him.

And Niu Dazhuang is indeed a homicide to the numbers, and others may be sloppy, but this point is very fine.

When the two reached the bottom together, Chen Qingyun asked, "How many steps?" ”

Niu Dazhuang said directly: "Five hundred and sixty-seven steps." ”

Chen Qingyun nodded, and suddenly said in a condensed voice: "Five hundred and sixty-seven steps." ”

As soon as these words came out, Gu Le suddenly changed color: "Wasn't it only five hundred steps just now?" Why is there so much more this time. ”

Chen Qingyun's gaze swept up and down, and said lightly: "I finally know why we haven't been able to find where they went, it turns out that the portal is not on both sides of the stone wall, but on this stone step." ”

Gu Le had already guessed: "You mean, these stone steps may be connected to many passages, but every once in a while, they will extend to different levels, so we will enter different places at different times, right?" ”

Chen Qingyun glanced at him: "Besides, is there a more appropriate explanation?" ”

Gu Le couldn't help but be silent, he really couldn't think of any other explanation.

And what Chen Qingyun said is really reasonable.

There are hundreds of layers up and down this stone step, the height is hundreds of meters, even if each layer is separated by ten meters, it can also be separated by ten layers, the stone wall is only three or four meters high, if there is such a thick thickness in the middle, it is normal to isolate a qiē sound and not hear the signal.

It's just that Gu Le still has a problem, and he really can't figure it out.

He immediately asked: "Director Chen, it's not that I don't believe you, it's really this question, it's a bit weird, I entered this tunnel twice, and finally arrived at the destination, it was the stone gate, we also opened the stone gate, and saw the situation inside, there is no doubt that it was the same as the first time I saw it, which means that we didn't go from the place." ”

Chen Qingyun pondered for a while, and then said, "Gu Le, what you said is right, but this is not without other possibilities. ”

Gu Le immediately asked, "What is possible?" ”

Chen Qingyun immediately said: "Think about it, this tunnel is long, we walk in it, because there is no reference, if the slope is small, we can't tell the height, and if the curvature is small, we can't see the change in direction, maybe the final result is the underground palace." ”

Gu Le was stunned, he really hadn't thought about this possibility.

After thinking about it carefully, I think there is a certain chance that it is right.

However, Niu Dazhuang immediately questioned: "No, if they finally lead to that stone gate, we should have seen them appear in the underground palace when we were there." ”

Chen Qingyun looked at Gu Le again: "Didn't he say it, this underground palace will give him face, without him, no one can enter." ”

Gu Le smiled bitterly, as if he didn't expect that this Chen Qingyun still had the heart to ridicule him at the moment.

He scratched his head: "Director Chen, even if I'm bragging, this place is too weird, I can't cover it." ”

Chen Qingyun said with a straight face: "I'm not sarcastic, it's true, if it weren't for that, I wouldn't be able to explain that they didn't appear in the underground palace later." ”

But this is not over, at this time Niu Dazhuang said again: "Also, if they can't get into the underground palace, they should think of coming out, we have been in and out a few times, and we have all gone out safely and unharmed, which means that there is no mechanism in the tunnel, but they haven't come out yet, it's been so long, isn't it strange?" ”

As soon as he said this, Chen Qingyun and Gu Le's hearts suddenly hung again.

Originally, they thought that the secret of the stone steps had been discovered, and the matter could be regarded as over, at least there was an explanation, although those people had not been found, they were certainly not in danger.

But Niu Dazhuang's words made them have to continue to worry.

Those people don't go in or out, so naturally they won't wait there, at least they have to send someone out to deliver a letter to them, or ask for help, but the key is that at this moment, no one has been found to go out, and the biggest possibility is that something happened to those people.

If it weren't for the danger, it would definitely be trapped somewhere and couldn't get out temporarily.

Gu Le was depressed, this matter was really troublesome and weird enough.

He asked, "Director Chen, what should we do now?" ”

Chen Qingyun was silent, looked at the two of them suddenly, and then said: "Two choices, is it to go out alone, wait for news outside, and the other two enter the dungeon to investigate, or let's enter the dungeon again now and see if we can see them?" ”
