What responded to me was still the sound of the grumbling piano.

The three of them were still singing, but none of them answered my question.

My heart was in turmoil.

I quickly looked overhead, and it was dark, and I held my flashlight high above my head.

I vaguely saw what seemed to be a large black shadow flashing in front of me.

It was just that with the light of my light, the shadow quickly dissipated in front of me, and seemed to be hidden.

"If you have the ability, don't hide!"

I gritted my teeth in anger, and it was obvious that the thing above my head had just dragged the three of them up.

Otherwise, how could a person suddenly disappear?

I looked at the wall.

The walls were smooth at the edges, carved with landscape maps, and had been artificially carved so that there were not many bulges for me to climb.

"If there are no conditions, you have to create conditions."

I didn't want to destroy the mural on the wall, so I fumbled around the edge of the wall to try to find the end of the mural.

Finally, at the very end of the wall, there was a blank space, and there was nothing on it.

I immediately pulled out the Soul Calming Spike, aimed it at the wall, and smashed it in.

"Cui Hao, you guys hold on, I'll be here soon."

I pressed against the wall, shouted inside, and then I stepped up my hand again, and drove two soul slamming nails into the wall.

With these two nails in place, I stepped on the Soul Calming Nails, took out the other ones, aimed them at the wall a little above, and slammed them down.

I nailed it diagonally upwards with the Soul Calming Spike, creating a path for me to climb up.

I stepped on the Soul Calming Nail and slowly climbed up the wall, but fortunately I had enough Soul Calming Nails to climb several meters high.

The higher I climbed, the more I felt my body tremble, and there was a faint tendency to fall.

It's too high here.

If you're not careful, you're likely to slide down the wall and strike another blow.

At this time, my cervical vertebrae were still aching, and I didn't want to fall down and hit my back and cervical spine again.

When I had climbed about five meters above the ground, I raised my flashlight and looked up.

There is indeed a pathway up there.

Almost two meters above my head, two long iron plates, about seven or eight meters long, spanned the top of my head and connected the two sides.

There are clearly edge platforms on both sides of the edge that can be climbed up. Above the head, there is a space about three meters high on the metal plate.

But it's already at the top.

"Looks like they've been dragged up, as long as I can grab the metal plate and climb up, I'll be able to go to the platforms on both sides and bring them back."

With the direction, I breathed a sigh of relief.

When people are in the unknown, they are in the most terrible situation.

I continued to climb up.

It's just a pity that the number of soul nails in this town is already insufficient.

But in my current state, trying to pry the soul suppression nail below out of the wall and take it down is even more a pipe dream.

If I'm not careful, I could just fall right from here, and I'll be bleeding from here.

I gritted my teeth and reluctantly put the hammer back into my backpack, pulling out the rope and hidden weapon from it.

I tied the rope to the concealed weapon, then aimed it at the iron plate and threw it at it.

Then, the rope quickly passed through the top of the iron plate, and the other end of the rope holding the hidden weapon fell from the other end of the iron plate.

I pulled the knot into my hand, quickly crossed the knot, and tied the rope to the iron plate.

I crossed it a few more times to make sure that I had pulled it into a dead knot, and then I pulled the rope down violently.

"It's relatively sturdy, I'll see if I can handle my weight."

I swallowed, grabbed the rope and slowly released my grip on the Soul Suppressor until I placed all my weight on the rope.

Fortunately, the rope was of good quality, and the knot I tied was stable enough, and the rope didn't break in the middle and didn't drop me off.

I breathed a sigh of relief and hurriedly grabbed the rope and began to climb up.

Luckily, there are only about two meters left, which is a breeze for me.

I quickly grabbed the metal plate, and with all my strength, grabbed the iron plate with both arms and jerked it upward.

Then I spun my body and jumped up in an instant, jumping onto the top of the iron plate.

I quickly stabilized my body, and immediately took out Shang Fang's sword, aiming it at the black giant shadow that I saw before I was vigilant.

At the same time, I held up my flashlight and shone it around.

"Nobody, is there anything else?"

I was relieved to see that there was nothing around me and no monsters as I had imagined.

I slowly grabbed the metal plate and moved it to the side little by little.

Finally, I came to the edge platform around me, and I stepped on it, and I put it down.

"We've finally arrived at a safe place."

I looked around, and it looked like a patio.

To be precise, the position we were in just now was like the bottom of a well that had been dug.

I climbed slowly to the edge of the well, along the wall at the bottom of the well, until I jumped to the ground at the edge of the well.

Around me was a rather large burial chamber, with no bottom visible all around, and there seemed to be more than just traces of artificiality.

The surface of the walls is pitted and uneven, and it looks like a natural phenomenon formed by the erosion of time.

But what worries me is that not far in front of me is a narrow road about three or four meters wide.

At the end of the road, there seemed to be a faint green light, which was extremely frightening in such an empty cavern.

Fortunately, I didn't see the black shadow just now.

At least I'm safe for the time being.

I moved as far away from the patio behind me as I could, and shouted a word forward with my flashlight.

"Cui Hao, are you there?"

It was silent, only my voice echoed in the empty tomb, as if I was still alone.

I took a breath and thought about simply lying on the ground and pressing my ears to the ground.

At this time, the land was very quiet.

The deafening singing just now, I couldn't even hear a sound, and even the strange sound of the piano disappeared completely.

"Why is there no sound?"

I slammed the ground three times, just as I was about to get up in disappointment.

But I never thought that I would hear three echoes from the ground.

To be precise, it was as if someone on the ground had responded to me and slammed the ground three times.

I was so excited.

"Cui Hao, is that you?"

I pressed against the ground and shouted to the bottom.

It's a pity that there was no response.

"It should be too far away, and you have to smash it."

I took out the hammer and slammed it three times against the ground, while silently sticking to the ground, waiting for the sound to echo.

As expected.

Just as I was stopping, there was a response from the front.

There were two thuds, and sure enough, someone was answering my call.

I briefly identified the source of the sound, it must have come from the faint green light directly in front of me.

"Eighty percent of that person is there."

I suppressed the uneasiness in my heart, tightened my grip on Shang Fang's sword, and slowly walked in the direction of the green light.

Every time I approached about five meters or so towards the green light, I would crouch down again and stick to the ground and hit the ground three times.

The good thing is that every time, there will be a response.

This also makes it easier for me to determine the other person's position and avoid me from falling on a fork in the road.

Finally through the path, the melancholy green light in front of it was becoming more and more obvious.

I could clearly see a large mural in front of me.

And in the center of the mural, there is still a melancholy green lake.

"Why does this look like it's the same as the one outside?"

I was relieved to see that it was a wall.

I immediately pressed against the wall, carefully groping for each stone brick on the wall.

However, it was not as I thought, there were no secret doors or cracks here, as if I had fallen into a desperate situation again.

"Strange, if there is no secret door, then where did the knocking sound just now come from?"

I thought about it for a moment, and quickly lay on the ground and pressed my ears against the ground.

"Bang bang."

I knocked three times, and soon the response came.

It's just that this voice suddenly made me bounce up from the ground, shivering, and quickly swung it in front of me with Shang Fang's sword.

Bang.

Shang Fang's sword smashed against the stone wall, almost cutting off a piece of the stone carving.

I came to my senses and immediately took a step back.

The voice just now was so obvious that it was clearly ringing in my ears.

To be precise, the sound seemed to come from less than a meter in front of me.

That is, it came from inside the wall.

"It's a wall again, how can it be a wall again?"

I quickly lay on the mural and knocked it three times the way I had just done.

Sure enough, the sound came from inside the wall.

And at the edge of the green lake, there was even a bit of rapidity in the voice.

"Cui Hao, is that you?"

I suppressed my nervousness and shouted at the wall.

However, I don't know if I can't hear it on the other side of my voice, or if I can't understand it at all.

The sound of banging on the wall continued, and there was no response from the other side.

"Whether it's or not, I'm going to have to find a way to open this wall."

Obviously, there must be a hollow inside this wall, and there must be a dark room inside.

Before I could figure out how to smash the wall in front of me, I suddenly heard more than one knock on the wall.

I couldn't help but put my ear against the wall again.

"Bang bang."

There was a constant sound of smashing walls, one of which was from inside the wall in front of me.

There were two other voices, which seemed to be coming from my left and right sides, respectively.

"Excuse me? Are there other secret passages in this wall? ”

I immediately lay on the ground, carefully analyzing the sources of the other two sounds.

Soon, my target landed on my left and right, the uneven stone wall.

"The sound seems to be coming from these two stone walls."
