Chang Fa didn't quite understand what sounds could be heard in this place, so he also calmed down and listened carefully to the sounds around him like Zhang Yancheng.

It's quiet, so quiet that there won't be any other sound at all, and when I listen carefully, there are only a few heartbeats and breathing, and the sound of footsteps on the ground.

If he guessed like this, Chang Fa felt that Zhang Yancheng should have heard a few footsteps.

So he also noticed the change in everyone's footsteps and walked forward slowly.

Changfa's hearing level is not faster than Zhang Yancheng's at all, so he can hear very clearly, and he can clearly distinguish the sound changes of several footsteps.

Now when he listens carefully, he can easily tell which of the fat man's feet is heavy.

And after walking like this for about half an hour, Chang Fa suddenly noticed a change.

When he concentrated on listening to all the footsteps, Chang Fa felt that he was still quite tired, and the appearance of this sound was relatively clear, and it directly reached Chang Fa's ears.

It was a resonant sound like stepping on a wooden plank, and according to this sound analysis, Chang Fa felt that the ground under their feet had become empty. And the thickness of this floor will not exceed ten centimeters.

After this abnormal sound appeared, Zhang Yancheng also reacted quickly.

Apparently knowing what that meant, he pulled a shovel straight out of his backpack, an iron-tipped shovel and a wooden handle.

He grabbed the head of the shovel and began to tap on the wall of the corridor on his right.

He taps very regularly, about every 20 centimeters, and the error before and after will not miss two centimeters.

Chang Fa listened to the sound of the shovel hitting the wall while paying attention to the shovel hitting the wall.

Slowly, he found a pattern.

At first, the sound was the sound of a shovel hitting a solid wall, but slowly, the sound began to muffle, and holes began to appear in the back of the wall.

And as the few people continued to move forward, the hollow in the wall became bigger and bigger, and the sound became more and more crisp.

Finally, after reaching a certain point, Zhang Yancheng stopped.

He pressed his oddly long fingers against the wall, closed his eyes and began to sense the changes in the wall.

At this time, Changfa can't imitate it.

Listening to the sound and watching the movement, Chang Fa felt that he could still compare with Zhang Yancheng, even if he was not experienced enough, but the sensitivity of his senses was definitely not much different, but when it came to the touch of his fingers, Chang Fa looked at Zhang Yancheng's fingers and understood that he couldn't compare at all.

Zhang Yancheng carefully sensed the changes on the wall, and his fingers kept sliding, as if he was looking for something engraved on the wall.

After about three minutes, Chang Fa saw Zhang Yancheng's eyes open suddenly, and his right hand suddenly exerted force, put his five fingers together, and slammed into the stone of the wall in unison.

I often subconsciously feel a pain in my fingertips.

The feeling of hitting a stone violently with your fingertips is unbearable just by imagining it a little.

But the truth is not very imaginable, the moment the five fingers of Zhang Yancheng's palm touched the stone, the stone instantly cracked, and then a hole was revealed in the back.

Zhang Yancheng eagerly reached into it, touched a mechanism in the hollow, and pulled it hard.

Chang Fa felt the stone slab under his feet suddenly shake, and he bent his knees in time, ready to fall.

Immediately after, the stone slab under his feet fell in an instant and flipped over.

Several people fell below at the same time.

Chang Fa was ready to fall, so he adjusted it in time, and at the moment of falling, his body twisted, fell directly to the surface, landed on his feet, and shook twice to stand firm.

Fortunately, the distance of the fall was not high, only three or four meters, and although several people fell, none of them were fallen.

Zhang Yancheng, like Chang Fa, adjusted his body shape the moment he fell, so he also landed on the surface of the rain steadily.

And the fat man was more miserable, and he fell on Lin in a daze.

Fortunately, he has a lot of fat on his body, otherwise he would have to fall out of something wrong this time.

And Li Jiao was much luckier, although he also fell, but half of his body fell on the fat man's belly, excellent shock absorption, he immediately stood up.

The only trouble was that the kerosene lamp fell to the side after it fell, and after a moment of illumination, it went out.

Li Jiao went over to pick it up, took out the flint in the package and wanted to light it again, but Zhang Yancheng stopped him.

"Don't light the lights. Zhang Yancheng arrived in a low voice.

When he was done, he pointed to the passage in front of him and said again, "Look. ”

Li Fake and the fat man were extremely uncomfortable in this dark environment, so they couldn't see the direction of Zhang Yancheng's finger at all.

But Chang Fa can be seen clearly here, because there is a light shining in front of him, in the direction that Zhang Yancheng pointed to.

Like moths trapped in the dark, several people immediately walked in the direction of the light.

It's about a hundred meters away, which isn't too far.

And when they arrived, Chang Fa saw the source of the light and was immediately stunned.

It turned out to be a phantom of light, the real light was above, and the light below was reflected from above.

That's a bit scary.

As we all know, stones are very strong at blocking light, and I have never heard of which stones can pass through light.

If the stone could pass through the light, then the ancient times would not have carved into the wall to steal the light", and people today will not use glass to make windows.

But now this fact was laid out before them, and the light did shine in from above, and the shadow of the light fell to the ground, forming a shadow in the shape of a dragon.

Chang Fa took a closer look and was surprised to find that the shadow in the shape of a dragon was none other than the dragon in the lamppost in the corridor with the dragon ring incense on it, the dragon coiled.

Chang Fa didn't even understand what this thing was, and he felt that he couldn't figure it out. But now he saw something even more amazing.

The light is reflected from the lamppost above.

In fact, if you think about it carefully, when Zhang Yancheng and the road they appeared in at the beginning would not have light, Chang Fa felt that there was actually a problem.

Because in the end, there was indeed a light shining into the corridor, and after the two of them came out of the corridor, they entered the location where the light was.

Now that I think about it, maybe the corridor is indeed isolated from the light, but the reason why there is light shining in it is not that there is a problem with the corridor, but that there is a problem with the light.

The transmission of this light is simply too strong.
