"Wang Wangyang, where are you?"

I rushed to the source of the sound, but I never heard Wang Wangyang's cry for help again.

As I shouted, there was silence all around, only my own voice echoing in the empty environment.

"Wang Wangyang, can you hear me?"

Realizing that something was wrong, Cui Hao and Zhang Xu also quickly squeezed to my side.

"What's going on? Wang Wangyang, what's wrong with that kid? ”

I shook my head and pointed ahead.

"Did you hear the sound coming from here just now? But how did the people disappear? ”

Cui Hao scratched his hair and circled around the edge of the wall.

"What the hell, how could this place disappear out of thin air? Could it be that there is some secret passage, this guy has fallen? ”

As he spoke, Cui Hao stretched out his finger and picked at the gap in the wall, trying to find the secret door here.

Zhang Xu came to the other side of the passage and groped on the stone wall.

I crouched down and groped for the ground, trying to find traces of cracks and secret passages on the ground.

"How can there be nothing?"

We groped this passage from beginning to end, but found no clues or traces.

The passage is about 20 meters long, and soon it reaches the bottom, and there is no fork in the road and no hidden secret door is found.

"There must be a secret passage here, he must have fallen down the passage."

Cui Hao didn't give up, and was still groping around.

Faintly, however, I heard the sound of a piano along the stone wall, which flickered far and near, spreading and wafting in our ears.

"Did you hear that?"

I covered my ears and the sound quickly became quieter.

I confirmed that it was not an auditory hallucination, so I immediately turned back and asked Cui Hao.

The two of them were stunned by my question.

"Hear what?"

I pointed to the wall and asked them to stick it in my vein.

"There's a sound here, and it's the sound of a piano, can't there be a living person here?"

The two of them were startled and immediately imitated me and stuck to the wall.

In an instant, Cui Hao's face turned faintly pale.

"I'll go, there's really a voice in there. And I seem to hear the singing faintly, but it's a small voice, have you noticed? ”

I nodded.

I also just heard that there seemed to be people in the wall following the harmony.

Beneath the darkness of the earth, the green light illuminated the three of us.

Even though we held a flashlight and illuminated a passage in front of us, the miserable sound of the piano in the empty and lonely tunnel was still terrifying.

Cui Hao swallowed, and it was extremely clear in this empty space.

"There is a sound in the wall, which means that there should be a secret passage here, right in this wall."

After saying that, he turned back to the other wall and listened.

The walls were cold, and he shivered from the cold.

However, I found that Cui Hao's face became more and more pale, and his fingers couldn't help but tremble.

"How is this possible?"

He turned his head and quickly pressed against the wall at the very end, then got up and lay on the ground to listen carefully.

Raising his eyes again, Cui Hao's face was full of horror, and his lips couldn't help but tremble.

"You, listen. On all three walls, there is the sound of a harp. Even if there are secret passages and dark rooms in the walls, it can't be all three walls, right? ”

My heart sank, and I immediately crouched down and stuck to the ground.

Guo Cui Hao didn't lie to me.

The ground was empty with the sound of the piano, and the man's singing voice became more and more distinct.

There was even a bit of tactfulness and sorrow in the voice.

It's just that the more I listen to it, the more familiar it feels.

"Listen, the sound of this underground doesn't look like Wang Wangyang, is this guy singing underground?"

But when I finished, no one answered.

It was still cold, and the two of them seemed to be so frightened that they forgot to answer.

"Why don't you speak?"

I looked up dissatisfied, but my eyes fell on the wall, and it was like lightning strikes.

At this time, in front of me, only Cui Hao was left sitting on the ground.

Zhang Xu, who was standing seven or eight meters in front of me just now, was gone.

What's worse is that he is holding a flashlight, how could he suddenly disappear into the tunnel?

"Cui Hao, where is Zhang Xu?"

I rushed to Cui Hao, shook his shoulders and asked about Zhang Xu's whereabouts.

Cui Hao looked up, his face full of horror.

"I don't know, I was just listening to you, and I just wanted to reply when I felt a flash behind me, I thought the flashlight was out of power, so I was going to tell Zhang Xu that I have a power bank here."

Cui Hao's voice trembled violently.

"But, the moment I turned around. I saw a two-meter-tall black shadow flash by, and the flashlight went out. Zhang Xu just disappeared. ”

I immediately got up and rushed towards where Zhang Xu had just stood.

"Cui Hao, don't move."

I shone my flashlight at the ground, and it was so clean that there wasn't even a scratch.

Although Zhang Xu's strength is insufficient, he has the ability to protect himself after getting along with us for a while.

If you are suddenly in danger, it is impossible not to struggle, not to resist, not even to make a sound.

"What the hell is going on?"

I held up my flashlight and shone it around the cave.

The cave was dim and quiet, as if it was just the two of us who came in, and Zhang Xu and Wang Wangyang were just people in our hallucinations.

"Little Manye, you lie down, you listen again. Do you hear that there seems to be another voice under the earth? ”

I was covered in hair, and immediately lay down to listen to the sound on the ground.

In an instant my blood flowed backwards.

"Cui Hao, is that second voice Zhang Xu?"

Cui Hao did not respond.

He didn't respond!

A sense of uneasiness swept over me in an instant, and I quickly looked back at Cui Hao.

At this time, there was no one behind me, and there were no marks or traces left by anyone on the empty stone cave floor.

"Cui Hao?"

My voice trembled, and I lay on the ground and didn't even dare to get up.

I don't know what the hell is going on this day.

Why did Cui Hao disappear quietly?

But before I could react, a third voice suddenly sounded in my ears.

The voice was still coming from underground, the voice was empty and quiet, and the three boys stood at three different angles, singing a song of sorrow.

However, this last voice is all too familiar to me!

Isn't that Cui Hao?

Cui Hao and Zhang Xu's voices gradually became louder, until they blended with Wang Wangyang's voice, and gradually wrapped my whole person.

"Where the hell are you?"

I didn't dare to touch the ground anymore, so I immediately got up and stood up, taking out Shang Fang's sword and holding it across my chest, watching out for the visions around me.

By this time, the singing had become more and more obvious.

The sound of the piano squeezed towards me along the perimeter of the wall, almost overwhelming me.

This voice can be heard even if it is not against the wall!

"Zhang Xu, Cui Hao, Wang Wangyang, can you hear me?"

I questioned loudly, trying to talk to them.

But all in vain.

Frightened to the bottom of my heart, I immediately took out a cigarette and stuffed it into my mouth, lit a fire and took a hard breath.

I calmed down a bit.

At this point, with my composure.

The surrounding voices also seem to be a little weaker.

However, this was only for a moment, and then the next second, it seemed that four speakers were placed around me, and the speakers were playing that weird and melodious tune frantically towards me.

The sound of the piano is mournful, like crying and complaining.

Cui Hao's voices also harmonized with the sound of the piano, as if they had endured indescribable pain and sorrow.

"Damn, don't play tricks here. If you have a kind, you will come out! ”

There can't be any living people underground, but I can't figure out what kind of thing could make such a sound.

Just as I stared around warily.

Suddenly, the surrounding sounds stopped abruptly, and there was silence all around.

However, this silence is even more terrifying than the noise just now.

I walked around for a week, looking around carefully for fear that something was hiding in the shadows.

And right now.

Suddenly there was a gale above me.

The next second, something grabbed my neck and pulled me up.

"yes, why didn't I think of that? Crown! ”

That's the only thought I had when I was being dragged on.

We've just scoured the walls around us and the floor.

But he ignored the top of his head.

We subconsciously follow the direction of the sound and search in the four.

We targeted the walls and floors around us, because there was no singing coming from the space above, so none of us thought that the singing might be overhead.

It's pulling me with a lot of force.

My neck was strangled by the dead son, and I was almost out of breath.

I was hoisted higher and higher, and I was quickly dragged to a distance of five or six meters above the ground.

If I continue like this, I'll have to be strangled to death sooner or later.

I struggled to use the last bit of strength to shake Shang Fang's sword vigorously, sliding down my neck fiercely.

The good thing is that I made the right choice.

I cut a long hole in the top of my neck, and I could feel the liquid spilling out.

There seemed to be a high-pitched howl above my head, and the next second, the thing that was tightly holding my neck suddenly shrank back.

"Gan, why don't you let me go down and leave!"

Six meters, two stories high, you can directly send it to the crematorium and put it in an urn.

Fortunately, the moment I fell, I reacted and quickly hugged my head, and at the same time formed a ball.

The moment I hit the ground, I landed on my back, and the blow to my back almost knocked me to the point of vomiting blood.

But fortunately, I protected my head in time, so I didn't hit the ground of the cave directly, kowtowing and breaking the bloodstream.

When my body stopped rolling, I spread out on the ground by the lake, quickly listening to the sound below.

At this time, the singing below is still the same, but the melodious sound of the piano seems to be only separated from me by a wall, and it is playing in my ears against the wall.

I was startled and quickly bounced off the ground.

But soon I was pressed to the ground again, and a dumb voice shouted below.

"Cui Hao, are you there?"
