"Wang Wangyang, where are you?"
I rushed towards the source of the sound, but I never heard Wang Wangyang's cry for help again.
As I shouted, the surroundings remained quiet, and only my own voice echoed in the empty environment.
"Wang Wangyang, can you hear me?"
Realizing something was wrong, Cui Hao and Zhang Xu quickly squeezed to my side.
"What's going on? What happened to that boy Wang Wangyang?"
I shook my head and pointed forward.
"Just now, did you hear the sound coming from here? But why are the people missing?"
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? Is there some secret passage that this guy fell into?"
As he spoke, Cui Hao stretched out his fingers and dug into the gaps in the wall, trying to find the secret door here.
Zhang Xu came to the other side of the passage and started groping on the stone wall.
I squatted down and groped the ground, trying to find traces of cracks and secret passages on the ground.
"How could there be nothing?"
We explored this passage from beginning to end, but found no clues or traces.
The passage was about 20 meters long. We reached the bottom quickly and found no forks or hidden secret doors.
"There must be a secret passage here, and he must have fallen down the passage."
Cui Hao didn't give up and was still groping around.
However, vaguely, I heard a sound of piano along the stone wall. The sound was far and near, spreading and drifting in our ears.
"Did you hear that?"
I covered my ears and the sound quickly became quieter.
I confirmed that this was not an auditory hallucination, so I immediately turned back to ask Cui Hao.
The two of them were immediately stunned by my question.
"What did you hear?"
I pointed to the wall and asked them to imitate me and stick to it.
"There is sound in here, and it's the sound of a piano. Could it be that there are living people here?"
The two of them were suddenly startled and immediately imitated me and stuck to the wall.
In an instant, Cui Hao's face turned pale.
"Let me go, there is really a sound in here. And I seem to hear a faint sound of singing, but the sound is very small. Did you notice it?"
I nodded.
I just heard someone singing along in the wall.
Under the dim underground, the green light illuminated the faces of the three of us.
Even though we held a flashlight to illuminate a section of the passage ahead, the miserable sound of the piano in the empty and lonely tunnel was still eerie.
Cui Hao swallowed, and it was extremely clear in this empty space.
"There is a sound inside the wall, which means there should be a secret passage here, just in this wall."
After saying that, he turned back to the other wall and listened.
The walls were cold, making him shiver.
However, I found that Cui Hao's face became paler and paler, and his fingers couldn't help but tremble.
"How is this possible?"
He quickly turned his head and pressed it against the end wall, then got up and lay on the ground to listen carefully.
Looking up again, Cui Hao's face was full of fear, and his lips couldn't help but tremble.
"Listen, listen. There is music playing on all three walls. Even if there are secret passages and dark rooms inside the walls, it's impossible to have them all on the three walls, right?"
My heart sank, and I immediately squatted down and pressed myself to the ground.
Guo Cui Hao didn't lie to me.
The ground was filled with the sound of the piano. In addition, the man's singing voice became increasingly bright and clear.
There was even a hint of melodiousness and sadness in the voice.
But the more I listened to this voice, the more familiar it became.
"Listen, does the sound under the ground sound like Wang Wangyang? Is this guy singing underground?"
However, no one agreed after I finished speaking.
The surroundings were still cold, and the two of them seemed to be frightened, completely forgetting to answer.
"Why don't you talk?"
I looked up dissatisfied, but my eyes fell on the wall, and I felt like I was struck by lightning.
At this time, in front of me, only Cui Hao was sitting on the ground.
Zhang Xu, who was standing seven or eight meters in front of me just now, actually disappeared.
What's even worse is that he was holding a flashlight. How could he suddenly disappear into the tunnel?
"Cui Hao, where is Zhang Xu?"
I quickly rushed to Cui Hao, shook his shoulders and asked about Zhang Xu's whereabouts.
Cui Hao looked up, his face full of fear.
"I don't know. I was listening to you just now. Just when I was about to reply, I felt a flash behind me. I thought the flashlight was out of power, so I planned to tell Zhang Xu that I have a power bank here."
Cui Hao's voice trembled violently.
"But, the moment I turned back, I saw a two-meter-high black shadow flash past, and the flashlight suddenly went out. Zhang Xu just disappeared."
I immediately stood up and rushed towards where Zhang Xu was standing just now.
"Cui Hao, don't move."
I shined my flashlight on the ground, and it was extremely clean, with not even a scratch on it.
Although Zhang Xu is not strong enough, he has the ability to protect himself after spending some time with us.
If you are suddenly in danger, you will never struggle or resist, or even make a sound.
"what happened?"
I held my flashlight up and down and around the cave.
The cave was dark 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 imagination.
"Master Man, please lie down and listen again. Have you heard that there seems to be another sound under the ground?"
The hair on my body exploded, and I immediately lay down and listened to the sounds on the ground.
Instantly my blood flowed backwards.
"Cui Hao, is that second voice Zhang Xu?"
Cui Hao did not respond.
He didn't respond!
An uneasiness swept through my whole body instantly, and I quickly turned back to look at Cui Hao.
There was no one behind me at this time, and there was no mark or trace 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 happened on this day.
Why did Cui Hao disappear quietly?
But before I could react, a third voice suddenly came from my ears.
This voice still came from underground, and the voice was empty and quiet. Three boys stood at three different angles, singing a sad song together.
However, this last sound is too familiar to me!
Isn't that Cui Hao?
The voices of Cui Hao and Zhang Xu gradually became louder, until they were mixed with Wang Wangyang's voice, and gradually enveloped my whole person.
"Where on earth are you?"
I didn't dare to stay close to the ground anymore, so I immediately stood up, took out Shang Fang's sword and placed it across my chest, watching for any strange phenomena around me.
At this time, the singing voice became more and more obvious.
The sound of the piano also drifted along the walls and squeezed towards me, almost suffocating me.
This sound can be heard even if it is not pressed against the wall!
"Zhang Xu, Cui Hao, Wang Wangyang, can you hear me?"
I asked loudly, trying to have a conversation with them.
But all this is in vain.
My heart became more and more frightened. I immediately took out a cigarette and put it in my mouth, lit it and took a long puff.
I calmed down a bit.
At this point, with my composure.
The surrounding sounds also seemed to be a little weaker.
However, this was only a moment. The next second, it was like there were four speakers placed around me, and the speakers were playing weird and melodious tunes at me crazily.
The sound of the piano is mournful, like weeping and complaining.
The voices of Cui Hao and others also harmonized with the sound of the piano, as if they had endured indescribable pain and sorrow.
"What the hell, don't act like a fool here. If you have the guts, come out!"
There couldn't be anyone alive underground, but I couldn't figure out what kind of thing could make such a sound.
Just as I was staring around cautiously.
Suddenly the sounds around him suddenly stopped, and everything was quiet.
However, this silence is even more terrifying than the noise just now.
I walked around in circles, looking around carefully for fear that there might be something hiding in the dark.
And right now.
Suddenly there was a strong wind above my head.
The next second, something grabbed my neck and pulled me up.
"Yes, why didn't I think of that? Over my head!"
That was the only thought I had when I was grabbed.
We just searched the surrounding walls and the ground.
But the top of the head was ignored.
We subconsciously follow the direction of the sound and search among the four.
We placed our targets on the surrounding walls and the ground, because no singing came from the space above, so none of us thought that the singing might be above our heads.
The thing pulling me was extremely strong.
My neck was strangled by the dead child, and I could hardly breathe.
I was hoisted higher and higher, and was quickly dragged to a height of five or six meters above the ground.
If this continues, I will be strangled sooner or later.
I was heartbroken, struggling to use my last bit of strength to swing Shang Fang's sword, and slid it down my neck.
Fortunately, my choice was correct.
The thing on my neck was directly cut open by me, and I could feel liquid splashing out.
There seemed to be a sharp howl coming from above my head, and the next second, the thing that was tightly strangling my neck suddenly retracted.
"Gan, why don't you let me put it down before we leave!"
Six meters, two stories high, if it falls, it can be sent directly to the crematorium to contain the urn.
Fortunately, the moment I fell, I reacted quickly, hugged my head tightly, and rolled my body into a ball.
The moment I hit the ground, I landed on my back. The heavy blow on my back almost made me vomit blood.
But fortunately, I protected my head in time, so I didn't hit the cave floor directly and get bloody.
When my body stopped rolling, Hubian spread his body flat on the ground and quickly listened to the sounds below.
At this time, the singing below was still there, but the melodious sound of the piano seemed to be only separated from me by a wall, playing against the wall in my ears.
I was startled and quickly jumped up from the ground.
But soon I clung to the ground again and shouted something below in a hoarse voice.
"Cui Hao, are you there?"
