With this strange sound, Shen Li and I glanced at each other, and then looked at the steps under our feet.

However, there is nothing unusual about the steps under our feet, they look like ordinary stone steps.

Could it be that there is a hole in the staircase that makes a sound?

Without much thought, I continued to raise my foot and step up the step on my heel, and the moment I got down, the next step made the same sound......

"Buzz ......"

Yes! The almost identical sound indicates that the first step is not empty, but that the person who built the staircase has deliberately done it in some way......

But the people who built this step, why did they let it make a sound?

Of course I couldn't figure it out, I looked at Shen Li on the side, Shen Li also had a calm face, and it didn't seem that he had come up with a reason.

"Continue ......"

At this time, Shen Li opened his mouth in a low voice, I nodded without hesitation, and stepped on the higher steps again, and sure enough, this higher step also emitted almost the same low roar as the previous two steps.

He didn't stop, he stepped straight up all the steps step by step, and came to the door of the room at the top of the steps.

turned around and looked at Shen Li, who was still on the first step, but found that Shen Li frowned tightly, as if he had thought of something.

"What? What did you find? ”

I looked at Shen Li and asked, and Shen Li shook his head slightly.

"Jiang Wangsheng, listen carefully......"

After speaking, Shen Li actually retreated from the first step, and then stepped on the steps continuously, coming straight towards me.

For a while, the voices of the previous order and the next order were mixed together, so that after Shen Li finished stepping on the ninth order, all the low roars of the ninth order converged together.

"Uh-huh......"

In an instant, listening to the sound of these nine levels coming together, I thought of a language, and that was the Sanskrit sound of Buddhism!

Yes! Buddhist Sanskrit sounds, almost like this, are mixed together with several sounds that are almost identical, but subtly different, to form a sound that has never been seen before.

And this unprecedented sound, in the Sanskrit sound of Buddhism, often represents a certain kind of Buddhist mantra!

This ninth-order Sanskrit sound is a kind of Buddhist mantra!

I was horrified in my heart, and Shen Li beside me shook his head and frowned.

How could a murderous creature build this ninth-order Sanskrit sound......

"I don't know, it would be nice if Lin Mu was here, he must understand what this ninth-order Sanskrit sound represents."

I shook my head and looked back at the huge stone door on the steps.

Hui Guo has slipped into this stone gate, and his safety is, of course, the most important thing for me at the moment.

Of course, Shen Li also understood this, so he didn't continue to study this ninth-order Sanskrit sound, but stepped towards the huge stone gate with me, leaned on the side of the stone gate, and looked towards the stone gate.

Then, I only saw that in the middle of this stone gate, there was a huge underground cave, and only the four corners of the cave were lit with torches, and the light of the torches could not illuminate the entire cave space.

Grass...... So, how do we find Huiguo?

In a hurry, I was the first to get into the stone gate, and the moment I got into the stone gate, I couldn't help but shiver, because the temperature in the stone gate was much colder than the outside passage, and its resentment was incomparably rich.

It's like when we were working underground, Lin Mu and I felt the situation when we had dug half of the loess area......

Grass, could it be that this other civilization is really of the same origin as the evil hole, and this is really the source of the evil hole?

Uneasy in my heart, Shen Li also got into the stone gate and came to my side, and we didn't stop, leaning against one wall of the cave, and looked for Huiguo's trace in the dark.

I stared at the darkness of the cave in front of me until Shen Li, who was beside me, tugged at my shoulders and pointed to the cave wall behind us as I turned my head.

I took a look, and saw that there were huge murals carved on the wall of the cave behind us, and these murals were all murals of statues of some creatures.

It's just that the creatures in these murals are all very strange, such as being in human form, but having horns, and a thick neck and a head like a horse and a donkey......

Of course, because I was anxious to find Huiguo, I didn't look too much, and after scanning it, I looked at the dark places of the cave again.

And this time, just by a glance, I saw a figure suddenly flash in the range of the torch in the upper left corner of the cave in front of us, heading towards the area of the cave wall in front of us.

Of course, as long as it is a figure, it must be Huiguo!

Without hesitation, I pulled Shen Li and rushed towards the cave wall opposite us, however, when I pulled Shen Li to the center of the cave, I paused in a panic.

Yes, paused in the midst of the shock.

Because I only saw that in the very center of this cave, there was a black shadow outline, and this black shadow outline was the same black shadow outline I had seen before, like a giant spider......

With a "bang", Shen Li and I drew out our respective weapons, however, the silhouette of the giant spider-like black shadow in front of us was motionless, like a sculpture.

Gritting his teeth, of course, he was still anxious for Huiguo's comfort, so he didn't wait long, clenched the black knife, and stepped towards the silhouette of the giant spider-like black shadow in the center of the cave in front of us, step by step.

As we got closer, I realized that the giant spider-like black shadow in the center of the cave was really a sculpture......

Yes! It's a sculpture, but we can see from this sculpture that this giant spider-like black shadow clearly has a body similar to that of a human, but his limbs and torso are very long, so he can move on his elbows on the ground like a spider.

The only pity is that the sculpture doesn't depict the face of a giant spider-like creature, so we don't know what kind of face he really has.

Without thinking much about it, since it was just a statue, of course we would go around it and continue to run to the opposite side of the cave where Hui Guo had flashed just now.

The distance of more than ten meters, just in an instant, we reached the other side of the cave where Hui Guo ran just now.

He stared around, but he didn't find any trace of Huiguo.

Of course, this made me even more anxious, and at this moment, Shen Li pointed to the side of the cave wall we were leaning on at this time.

I looked along and found that what Shen Li was referring to was the corner of the torch that flickered on the side of the cave wall we were leaning against at this time.

And in the corner of the torch, there was a stone door!

Yes! At this moment, there was a stone door in the corner of the cave wall we were leaning on, but this stone door was not as big as the stone door we ran through in the dark passage, but at this time, this stone door was clearly open!

Without thinking much about it, he and Shen Li hurried over against the cave wall.

Leaned against the stone door and waited for a moment, then poked his head out into the stone door.

Then, I only saw that in the stone gate was a boxy stone chamber, and its area was only half the area of the cave outside.

Moreover, the stone room in this stone gate actually has a stone bed, and on the other side of the stone bed, there is a fence of the same stone, and at this time, there is really a figure standing in front of the fence...... it!

Without the slightest hesitation, I rushed into the stone room with Shen Li, and after a few big strides, I went to the stone fence and grabbed the figure in front of the fence.

No accidents, of course it's Huiguo!

"What is running around? Didn't you keep up with us? ”

I stared at Hui Guo and couldn't help but whisper.

However, instead of reacting to my low drink, Huiguo stared at the stone fence with a smile on her face.

I couldn't help frowning, and I also looked at the stone fence, and just one glance, my heart was groaning.

For it was only in this stone fence that I saw a nest of black eggs......

Yes!

There were weeds in the stone fence, and among them was a nest of black eggs.

These black eggs look about the size of ostrich eggs, but they are so black that I can't help but feel a little hairy in my heart.

It's as if this nest of black eggs is a small black hole vortex, no matter how you look at it, it is pure black, even darker than the darkness without light......

"How can it be so dark?"

I turned my head to look at Shen Li and frowned, but Shen Li shook his head slightly.

"Not a black ......"

"Not black?"

Of course, I didn't understand what Shen Li meant, but Shen Li stretched out another finger and frowned slightly on the embroidered spring knife he held in his other hand.

Then, Shen Li's finger was cut by the sharp embroidered spring knife without accident, and after she cut her finger, she put her finger into the stone fence, and dripped the blood from the finger scar on one of the black eggs.

For a while, blood dripped and smashed on the black egg, dyeing the surrounding weeds with blood red, however, the black egg did not change at all, it was still pitch black, as black as a black hole abyss!

"See......"

Shen Li withdrew his fingers and shook his head.

"It's not black, it's just that we can't see it......"

I listened, and of course I understood what Shen Li meant.

Ordinary people who are not inhumans cannot see the ghosts and ghosts without entering the land of extreme yin, unless the ghosts and ghosts take the initiative to appear.

And in some coincidences, ordinary people can only see a dark shadow when they see ghosts and ghosts, and that is because they are not in the same world as each other.

That is to say, the fact that the egg is so black at this time does not mean that the egg is black, but that we cannot see the egg clearly, because the egg is not a thing of the same world as us......

"Grass, this other civilization is also an invading race......

I couldn't help but curse, and Shen Li shook his head slightly.

"As I said before, this other civilization is likely to have the same origin as the evil hole, and the evil cave is the 'plague' that invaded the world......"
