Suddenly, I was shocked.

"I didn't notice just now, these finger prints are completely wrong."

I shook my head and immediately pressed my finger up.

Really.

One of the fingers is actually only half.

The little finger looked unusually short as if it had been cut off by something.

It is one knuckle shorter than normal.

However, since it was from below, this small anomaly was covered by this dense palm mark, and I almost didn't see it.

"The man with four fingers, the little finger has been injured. It doesn't look like it's one of us, and it's eighty percent of the time someone else here. Either that's the dead. ”

As I was thinking, there was a sudden commotion behind me.

And I'm sure I heard it right.

This time the sound came from the stone wall behind me.

"Who?"

I looked back, but there was still no one to be seen.

The moment I turned around, the footsteps rang out again.

Or maybe the footsteps were coming towards where I was.

The sound is extremely clear.

Since I was on it, the range of the flashlight became larger, and there was no visible figure in my visible range.

Zhang Xu was so frightened that he shrank into the corner and shouted at me.

"That guy is going to ask for your life, you jump down quickly, if you continue like this, you will die."

I shook my head and stared calmly at the wall.

The handprints on it did not increase, and the sound of the footsteps was more pronounced than before.

And I could hear it very clearly, and it was like I was walking over.

Just as the footsteps were about to reach me, I vaguely felt an echo in my ears.

Or not an echo, but two voices.

The footsteps seemed to overlap, and there seemed to be a more subtle footstep sound, actually coming from above my head?

"What the hell, how do these two footsteps feel exactly the same?"

Not only are they the same frequency, but the mild size is almost exactly the same.

I carefully pressed my ear to the wall and listened silently to the sound from above.

Really.

Through the heavy walls, I could hear someone walking around on it.

The footsteps were heard clearly through the stone wall above our heads.

And the sound was almost identical to the footsteps on the ground.

"Could it be that these two footsteps are exactly the same?"

Thinking of this, I reached out and tapped the top of my head.

With my banging.

The footsteps above stopped all at once, and it was obvious that the people above had noticed the sound below us.

I took a breath, then pressed my mouth against the stone wall above my head and shouted at it.

"Anyone?"

Immediately afterward, I heard Cui Hao's response coming from under our feet.

It's just that the sound is relatively quiet, and it is almost completely incomparable to the footsteps just now.

"Little Manye, is that you?"

I breathed a sigh of relief.

"Could it be that this is not a mechanism set up in the dome and under it to scare tomb robbers, but the footsteps of real people as they walk? It seems that when I was just nailing the nail, the noise I made was too loud, and then I attracted Cui Hao and them. ”

Thinking of this, I looked up at the dome.

"But how is this divided into two levels? How did they get up there again? ”

But it's too hard to talk to the wall like that.

In addition, through the thick stone roof, it is extremely difficult for this sound to reach our ears.

So I gave up communicating.

"Cui Hao, you want to find a way to let Wang Wangyang walk again, in this way, you take two steps and stop, and take two steps to stop. With this rhythm, I know that the footsteps belong to the two of you. ”

With all my strength, I shouted this sentence to the top of the rock, and I didn't know if the two of them could hear it.

Soon, however, I could clearly hear footsteps beneath our ground, and it was exactly two rings and one stop.

"Sure enough, the sound from above was inaudible, and it went straight to the floor beneath our feet."

In this way, the footsteps that followed me before were not following the two of us.

On the contrary, Cui Hao and Wang Wangyang, who were above our heads, were walking, which made such footsteps.

If that's what you say, then everything makes sense.

I briefly instructed Cui Hao to pay attention to safety.

Then I grabbed the nail and jumped off it, and then I began to look closely on the ground.

"The ground was clean and level. If there is a substance similar to soundproof cotton on the stone walls on both sides and above the head, this makes it impossible for the sound from above to be transmitted at all. But there is also a solid interlayer embedded in the middle of the soundproofing cotton, which leads from the top to the bottom, directly connected to our floor. This means that the sound above cannot be transmitted directly through the air, but can be transmitted to our floor through the mezzanine in the center, so it all makes sense. ”

In solids, sound travels relatively quickly.

At least it's much less than the volume lost in the gas.

If there are soundproofing devices on the sides and overhead, and they transmit sound to the soles of our feet through some special solid layer.

Then there is a high probability that this effect can be achieved.

I couldn't help but take a breath.

"What kind of capable people can set up such a mechanism."

But what happens to the agency has nothing to do with us now.

Now the most important thing is how we should get out of this place.

And if the footsteps above were left by Cui Hao and Wang Wangyang, then the finger marks on the ceiling could never be the two of them.

It also proves that there are third-party people here.

Zhang Xu saw that I was stuck by the wall for a long time and did not move, so he came to my side worriedly.

"How are you? Did you find something? ”

I briefly told him my speculation and finally told him not to worry.

"If my reasoning is correct, then it means that the two of us are safe for the time being, and this footstep is not a threat to us."

I pointed to the ceiling above my head and said what I had just felt.

"I think it's the handprints on the ceiling and the prying eyes that I perceive consciously or unconsciously that are more dangerous."

Zhang Xu was relieved when he heard that Cui Hao and the others were likely to be above our heads.

"If that's the case, then we're safe."

I nodded, just about to speak.

But suddenly, I heard a knocking sound from below, followed by a faint sound of Cui Hao shouting.

"Come up, I'm looking for something for you."

I nodded and climbed back to the top of the wall, continuing to try to shout at them.

What the two of them said made me stiffen.

"There is a child in this place, about 1.5 meters tall, we have seen this shadow, and it flashed in front of us and disappeared. Anyway, I would like to remind you guys to be careful. ”

It's too much effort to talk like that.

I briefly exchanged information on our side, and immediately jumped off the wall.

My legs trembled.

Even if you step on the soul suppression nail, but after all, the position is too high, and you have to keep talking to the top of the wall, which is an extremely physically demanding thing.

Based on the information we just exchanged, it was as if they were trapped in a passageway.

The passage is straight ahead, without any forks.

However, both sides of the passage were blocked by stone walls, and there was no way to get out.

When Zhang Xu learned the news, he became even more nervous.

"What then? Are we going to be trapped underground, sealed like this all the time? ”

I think it's divided into two floors, and it definitely makes sense.

And judging by the mechanism and the sophistication of the mechanism set up in this place, we may be able to figure out why it is divided into two layers, and we will be able to find a way to escape from here.

I sat on the floor and thought carefully.

The minutes ticked by, but I didn't come up with an answer.

The channels are all roughly the same, but I can't see the situation above clearly, so naturally I can't compare them accordingly.

Thinking of this, I simply leaned on top of the wall again and shouted my plan to the two people above.

"In this way, you two will continue to walk until you reach the end of the passage, and I will follow in your footsteps. I'd like to see if our channels overlap exactly. ”

If the structure of our upper and lower passages is not the same, then at this dividing intersection, there may be clues and information that we can find.

The two of them agreed to my request, and immediately I heard footsteps under my feet and walked forward.

I'm not far behind.

But suddenly, I noticed that the footsteps were walking directly behind the wall when they reached a certain wall.

Instead of turning to the right like us, he continued to walk straight ahead.

"Don't go, stop."

I couldn't get my voice out, I couldn't communicate with them, so I had to stand there and be anxious.

I groped the walls carefully, carefully inquiring about every grain of the stone on it.

"What the hell is going on? Why did the two of them disappear when they came here? ”

As I fumbled with the wall, I suddenly felt as if the wall in front of me had suddenly disappeared.

Before I could react, the man plunged headlong into it.

"What's that?"

I immediately drew Shang Fang's sword and quickly slashed around, for fear of being attacked by something hidden in the shadows.

With a thud, I fell to the ground.

I realized that I hadn't been attacked by anything, but I had entered another passage, which was completely different from the one I had just had.

"What's going on, how did I get here?"
