Gao Chao and the fat man didn't notice Xia Qing's change, because the change was really subtle, and even Xia Qing himself only vaguely noticed something.

Hearing her say this, Gao Chao was still a little puzzled, although his task was only to assist Xia Qing in completing her research work, but for Gao Chao, his character determines everything, for all the things he has experienced, he has a "reluctant" heart, he is a person who can't be confused.

The fat man is different from Gao Chao, at this moment the fat man heard Xia Qing say this, and then said happily: "That's great, Xia Qing, is it that if you find the ruins, our task will be completed?" ”

Xia Qing said with a smile: "It's hard to say this, because I don't know what it means to return to the ruins, that's exactly what I want to study, so if I find it, it should be said that most of the task is completed." ”

The fat man grinned and said, "Huh? Only half? Oops, this is really going to kill you. ”

At this time, Gao Chao said solemnly on the side: "Xia Qing, I don't care what you are studying, but I have to clarify a principle now." ”

Xia Qing looked at Gao Chao's face, and had no choice but to say, "Please speak." ”

Gao Chao said: "When you find the ruins, no matter what you want to study, if I think there are certain factors that may lead to life-threatening, then the fat man and I will immediately ask you to terminate your research, and then whether you agree or not, we will take you out immediately!" ”

Xia Qing knew that Gao Chao was not joking, she knew that Gao Chao had already sensed the danger that might appear through some things in this tunnel at the moment, so she would say these words at this juncture.

So Xia Qing sighed and said, "Lao Gao, do I have the right to deny your principles?" ”

Gao Chao said coldly: "No." ”

Xia Qing shrugged his shoulders and said helplessly: "Okay, I already understand your principles, let's continue." ”

Gao Chao nodded in satisfaction, and then walked forward alone with the torch.

The fat man reacted on the side, and then said to Xia Qing with a smile: "Miss Xia, I always thought that workers like us had no right to put forward principles at all, but I didn't expect that I could counterattack now, it's okay, don't worry, if it's really dangerous, I will carry you as soon as possible!" ”

Xia Qing ignored the fat man with a straight face, and walked forward with a torch, the fat man secretly smiled at the end, and couldn't help but feel a little admiration for Captain Gao.

In this way, the three of them walked all the way down this dark tunnel for more than two hours, but everything around them seemed to have not changed in any way.

The stone walls inside the tunnel are still covered with droplet-shaped, smooth black recrystalline stone, and the width, height, and even the downward slope of the tunnel have not changed at all.

Gao Chao began to be a little suspicious, he remembered what had happened in Xia Qiu's villa before, he still remembered that it was also a tunnel, but it was quite narrow, and in that tunnel, they encountered "ghosts hitting the wall".

The fat man and Xia Qing were actually thinking about similar things, after all, they had been walking in this tunnel for more than two hours, but they didn't see a trace of change, this is somewhat unreasonable, is this tunnel endless? Two hours of downhill journey, how deep has that gotten down?

The fat man finally couldn't help but question the first one, he stopped and shouted, "Rest! I ask for a break! Where is the head of going on like this? We can't just keep going like this, can we? ”

After speaking, the fat man even sat on the ground, shook his head and began to sigh.

Gao Chao and Xia Qing also stood still, Xia Qing was a little embarrassed and a little helpless, after all, she didn't know anything about this place, and she didn't know anything about it at the moment, if she went on like this, it was still unknown whether she could get to the place she was looking for.

Xia Qing was helpless, so he looked at Gao Chao, hoping that Gao Chao could persuade the fat man to let him stand up and continue walking.

But at this moment, Gao Chao looked at the fat man, but he didn't even have a little expression on his face, if he looked closely, he seemed to have a little expression, but it was definitely a cunning smile.

In fact, Gao Chao didn't want to stop the fat man, he even hoped that the fat man could continue to carry forward this kind of kung fu of sitting on the ground and playing tricks, because if this was the case, they wouldn't have to go down any further, and now they walked for more than two hours, if they counted, they should already be 1 km underground, you know, this depth is definitely not a joke.

Gao Chao once read an article, that is about the article about underground drilling, the article wrote, so far, the world's deepest drilling project, was the former Soviet Union in the seventies of the last century began, it was called the "Kola ultra-deep well", the drilling work persisted for 24 years, and finally reached a depth of nearly 13,000 meters, that is, a depth of 13 kilometers, but in the end this Kola ultra-deep well project was forced to stop, the reason for its stop is varied, the official version is that the research funds are tight, so it was forced to stop, The popular folk theory is that when the depth of the well was close to 13,000 meters, in the sound data collected 13 kilometers underground, there was a strange, disturbing sound, which the scientists who heard described it as a very creepy sound, close to the "roar of man", and some other people at the scene also swore that "the sound sounded like the cry of a sinner in hell", so the huge cost of the "Kola ultra-deep well" project was sealed forever.

And now, their location, although not as deep as 13 kilometers, but the depth of 1 kilometer, has reached an unimaginable level, you must know that there are records in the world, the deepest cave that human beings have ever found, is only in the Kulu Boyara Cave in Georgia, its depth is 2197 meters, that is, about 2 kilometers, and the deepest cave found in China is in the stone cave in Tianxing Township, which is only 1026 meters deep, which is probably the same as their current location.

So Gao Chao was thinking, what could there be in such a deep position? Do you want to go on any longer? If you go on for another hour, no one knows what's going to happen in this tunnel.

So Gao Chao also sighed very tiredly, and looked at Xia Qing helplessly, he didn't say anything, but Xia Qing already understood what he meant when he saw his appearance.

You must know that Xia Qing is not an ordinary woman, ordinary women will not come to such a place, and the target she needs to look for is not ordinary, so she will not be willing to return with them because of the withdrawal of Gao Chao and the fat man, and walk back from here with her head down.

So Xia Qing held the torch and just smiled at Gao Chao, Gao Chao looked at Xia Qing who was smiling, but he was stunned for a moment, he couldn't understand what Xia Qing meant at all.

At this moment, Xia Qing looked very sorry, she sighed softly, and still smiled: "Thank you for being able to accompany me here, this is already a very difficult matter, but I know that you don't want to go on anymore, in fact, I understand your thoughts......"

At this point, Gao Chao and the fat man also lowered their heads a little helplessly, Xia Qing saw it in his eyes, but said with a smile: "In this case, let me go down the road alone, I won't blame you." ”

As soon as Xia Qing said this, Gao Chao raised his head and looked at her in surprise, Gao Chao didn't expect her to insist on walking alone, he originally thought that Xia Qing would give up and continue to move forward because of the opposition of himself and the fat man, but now there is such a situation, which makes him not know how to deal with it for a while.

Xia Qing looked at Gao Chao's expression, but she misunderstood Gao Chao, and then she quickly explained: "Lao Gao, please rest assured, I will not embarrass you, I declare, your task is complete, you just need to follow the original route and return to the south side of Gawa Gapu Snow Mountain, as long as you wait for the arrival of rescue there, they will not die without help, you will be taken away from this mountain area safely by them." ”

After speaking, Xia Qing let out a sigh of relief, as if she had relaxed a lot, but the person who should have relaxed would never be hers.

She looked at the fat man sitting on the ground at the moment, and the mastery who was looking at her with some munas at the moment, and then she waved her hand and said with a smile: "Goodbye, comrades! Good luck! ”

After speaking, before Gao Chao and the fat man could react, she had already turned around, raised the torch in her hand, and continued to walk along the dark tunnel, ahead.
