After ten minutes, Yu Lie and the others finally returned to the place where they started. After a while, they finally figured out what was going on.

It turned out that twenty minutes after Yu Lie set off to look for Zhou Ran, Zhou Ran came back, but he came back from the west.

It's such a coincidence that the two went against each other.

After landing, Zhou Ran also discovered the strangeness of this place, and wanted to figure out what was going on, so he wanted to study the structure of the stone wall. I didn't expect the fog to be too big, and I accidentally got lost.

He followed the path he remembered, but as he walked farther and farther, he shouted loudly and no one answered, and there was no sound on the walkie-talkie. And, all the electronics on his body were out of order.

He didn't dare to wander around anymore, he just hoped that someone would come and look for him if he found out that he was missing. However, after waiting for more than ten minutes, no one appeared.

At this moment, Zhou Ran was completely panicked!

However, at this moment, there was a murmur on the walkie-talkie, which had been silent, and the malfunctioning electronic equipment was restored.

Zhou Ran also discovered one point: the fog gradually thinned.

Then, the compass on the electronic device could also be used, and Zhou Ran followed the instructions to the east, and returned to the starting point in a short time.

Lu Xian and the others were pleasantly surprised, and hurriedly contacted Yu Lie, but no matter how they called, no one responded.

The missing are back, and the searchers are missing again!

Zhou Ran suggested sending someone to find it, but Lu Ran vetoed it, with his rescue experience, the best way was to wait in place.

But after waiting for about three hours, there was no response from Yu Lie and others.

Just when everyone was at a loss, Yu Lie's voice came from the walkie-talkie......

"What!" Yu Lie almost jumped up, "Three hours? ”

"That's right." Lu Xian looked at him suspiciously.

Yu Lie remembers very well that although his electronic equipment failed for a while, the mechanical watch on his wrist kept working. From the time he set off to the moment he last contacted Shanglu, he looked at the watch three times.

The first time was fifteen minutes after departure, the second time was at 1:06 p.m., and the last time was at 1:35 p.m. Counting the ten minutes of the final return trip, it adds up to less than two hours.

How could it be three hours?

"No, according to the time, it should be ...... by now"

Yu Lie said as he looked at his watch, and when he saw the pointer pointing, he was stunned.

Half past three in the afternoon!

Yu Lie suddenly grabbed Lu Xian's wrist, and was stunned when he saw that his watch was also pointing at half past three.

"Are you three paying attention to the time?"

Yu Lie asked the three team members who were following him, and he still didn't believe that he could be mistaken.

The three of them shook their heads one after another.

Yu Lie couldn't figure out what was going on for a while, he closed his eyes and tried his best to remember everything that had happened.

That's right, absolutely not mistakenly, it's two hours.

So why is there a one-hour time deviation?

Thinking of the word "time deviation", Yu Lie suddenly opened his eyes.

Assuming that there is a "time bias", is it possible that the space is also biased? If that's the case, everything is clear.

As they walked eastward, the space crept into a deviation, and they were unaware of the change. So much so that without turning, without turning back, the direction in which they walked changed.

If they change direction, they will go in the opposite direction, and they may go further and further, and they may never get out.

When they get to the edge of the "spatial deviation", which is the last marking point, they turn around and correct the direction.

Yu Lie was glad that he had made the right choice, otherwise......

However, what are the causes of "temporal deviation" and "spatial deviation"?

He was just about to say what he thought, but he realized that it was just his own speculation, and if he did, it would inevitably cause panic. Moreover, their main mission this time is to rescue ......

In addition, the failure of communication equipment and electronic equipment is also a mystery.

Thinking of this, he looked at Zhou Ran, but he didn't expect Zhou Ran to be looking at him as well.

Zhou Ran had already seen his abnormality, but he didn't ask, but said in a low voice: "Captain Yu, what should I do next?" ”

Yu Lie knew that he was reminding himself, and saw that the team members were also waiting for him to make an idea, so he quickly thought about it.

"We advanced almost a kilometer east and found no signs of human presence. Moreover, since Professor Zhou was able to come back from the west, it means that it is relatively safe there. Yu Lie said and glanced at everyone, "My opinion is to search west." ”

"Agreed." Lu Xian was the first to agree.

Everyone nodded.

"Professor Zhou, what do you think?" Yu Lie said to Zhou Ran.

"Our survey team listens to you."

"Okay, time is pressing, let's go!"

The group slowly advanced westward, and there were people in front and behind the rescue team, with the front being led by Lie, and the rear Lu was instantly broken, and the survey team was sandwiched in the middle to ensure safety.

After walking for about half an hour, nothing happened and nothing unusual was found. However, the passage to the west seems to be getting narrower. Moreover, the light of the flashlight is getting farther and farther away, indicating that the fog is continuing to thin.

"Stop!"

With Yu Lie's deep voice, the group slowly stopped.

Before asking, the crowd suddenly fell silent, because they saw the stone wall in front of them, which meant that they had come to the end of the passage.

"Is it going in the wrong direction?" This was Yu Lie's first reaction.

When the four "self-response lights" were turned on, they could see the whole picture.

Although it is still gray, it is much clearer than before, the stone wall is uneven, and the whole is relatively smooth, as if it was smoothed out by both hands. It's still dark gray, just a little whitish, like polluted snow.

What's even more surprising is that there is an uneven stone wall above the head, about ten meters high, and there are small stone pillars similar to stalactites hanging in some places, but the color is also whitish dark gray.

The rescue team began to survey and survey the surrounding area, and the survey team began to study the structure of the stone wall in an attempt to discover the cause of this scene.

"It's like a cave." Zhou Ran said, "Look, isn't that a 'stalactite'." ”

"Well, it does." Yu Lie replied, "I don't know when we entered this cave. ”

"Anyway, it's all connected, and if you can get in, you can get out."

"It's weird." Yu Lie said suddenly.

Zhou Ran looked at him curiously and asked, "Captain Yu, what did you say?" ”

"Before I set off, I started counting the time, and based on the distance of the markers and the speed at which we were traveling, guess what pattern I found?"

"Is that happening again?"

Yu Lie naturally understood what he meant by "that situation".

It turned out that Yu Lie noticed that as they advanced, the time taken between markers at the same interval was different.

He walked the first set in three minutes and eight seconds, the second set in two minutes and forty-five seconds, the third set in two minutes and thirty-two seconds, and the fourth set in two minutes and thirty seconds, and each of the next sets held steady at about two and a half minutes.

Nothing happened during this period, which excludes the influence of external factors, and their speed of travel remains basically the same, and there will not be much deviation, which excludes internal factors.

So, what exactly is the cause of the time difference? Is it some unknown factor?

Yu Lie couldn't figure it out for a while, and told Zhou Ran what he thought.

"Could it have something to do with the fog here?" Zhou Ran said thoughtfully.

The problem was already noticed during the period when he was "missing" to the west.

At first, where they landed, the fog was relatively thin, and the communication equipment and electronic equipment worked normally. After he unconsciously walked a little west, he found that the fog there had become thicker, as could be seen by the range of the flashlight.

Then, his walkie-talkie and electronics malfunctioned, and when they were restored, the fog was thicker.

After he said this, Yu Lie began to recall the situation of the search. Indeed, when electronic devices fail, it is when the fog is thicker.

"You're right, I think there's a big possibility."

"That's not the only explanation, though." Zhou Ran said, "There is another possibility......

"What is possible?" Yu Lie asked.

In fact, as an experienced rescue captain, Yu Lie should be able to think of this factor, after all, it will be encountered in many situations.

Perhaps, there were too many strange things encountered today, which affected his judgment.

"Magnetic field." Zhou Ran said.

"Yes, Magnetic Field!" Yu Lie slapped his thigh, and then he came to his senses, "How did I forget this." Maybe it's the magnetic field that's at work, and the mechanical watch is not affected. ”

"Captain Yu, have you noticed that this place gives people a kind of... It's a strange feeling. ”

"Professor Zhou, I'll tell you the truth, since I came down here, I felt that everything was full of weirdness!"

"First of all, from the space and location here, it is almost certain that it is the 'epicenter' that caused this abnormal tremor, but it is so clean and tidy that even the stone walls are smooth. What's going on? Secondly, this fog has been present since it went down to more than fifty meters from the ground, how did it form? Finally, there is the phenomenon of puzzling 'getting lost', or 'temporal deviation' and 'spatial deviation', how can this be explained? ”

Yu Lie told the mysteries in his heart one by one, and then breathed a long sigh of relief, as if a big stone in his heart had finally landed.

Zhou Ran agreed with his statement, so he nodded and said: "What you said is very comprehensive, if you want to find out the truth of this abnormal shock, you must answer these questions one by one, how easy is it!" ”

Yu Lie also knew the difficulty, and not to mention these problems, he didn't know what kind of danger would await them next......

However, Zhou Ran's next words subverted his cognition.

"In addition to these questions, there is another point that I find strange."

"Tell me about it." Yu Lie said.

"This deep crack splits the huge Kunlun station in two, and we will inevitably investigate from here, and the rest will be natural. We went down, surveyed, and asked questions, but none of them could be solved. Now that we have come to such a dead end, why is this happening? ”

Yu Lie looked at him blankly, thoughtfully.
