Xiao Ning didn't know where he had come, it was pitch black, he couldn't see his fingers, and it was difficult to predict what kind of danger would exist around him.

Xiao Ning stayed in place, clutching the pistol tightly, not daring to move at all.

In an unfamiliar environment, the best way is to wait and see what happens.

Not only is it terrible to be dark, but it's also terrible to be quiet!

Except for the sound of Xiao Ning's body trembling and the sand and gravel on the ground, there was no other sound!

Absolute darkness combined with absolute silence can easily break down a person's psychological defenses.

With the passage of time, even if Xiao Ning was a big man, he was a little panicked.

What to do? Get up and grope along the darkness?

He regretted it a little, why didn't he bring a fire fold with him?

Xiao Ning sighed, blindly waiting, there was no way, he decided to explore it himself.

Xiao Ning got up along the wall, this wall was a little wet, there may be an underground river around, and the moisture steamed up and attached to the rock surface.

Ku Ci sounded, and it was obvious that Xiao Ning stepped into the puddle.

It seems that there is some stagnant water in this place!

Touching the wall all the way forward, Xiao Ning could feel that the wall was curved, and he should have turned a big bend.

After that, the rest of the road is all straight, except for the occasional ups and downs.

Xiao Ning estimated the time, he had probably walked for more than half an hour, and he was afraid that he would be five or six kilometers away.

"If you bring your mobile phone and the mobile phone has a signal, you can start a live broadcast to do a desert island exploration show!"

"With the effect of this show, the big rocket can't be swished?"

Xiao Ning, who was bored, had a lot of wild ideas in his mind.

"Ahh

Suddenly, Xiao Ning was taken aback, and the right foot he stepped out of the air missed!

Fortunately, even if he took it back, otherwise he would have to fall into an unknown cave again!

Xiao Ning took a few steps back, then crouched on the wet surface, his arms reaching forward, groping on the ground.

Xiao Ning touched the hanging place, he pouted his buttocks, moved forward, and gestured forward with both hands.

Here, there seems to be a relatively deep pit, the length is not long, only about half a meter, you can jump over.

Xiao Ning didn't hesitate and got up and jumped over the hole.

After walking for more than half an hour, Xiao Ning regretted it a little, he might as well stay where he was and try to climb out.

If you go on like this, when will it be a head?

If you stay in the dark for a long time, you will become very sensitive to light!

After walking for an hour and a half, Xiao Ning finally found a glimmer of light in front of him!

Xiao Ning quickened his pace and ran towards the light with some excitement.

The light became more and more dazzling, Xiao Ning covered his eyes, and slowly opened his squinted eyes.

After getting used to it for a while, I was finally able to see the situation in front of me.

At this time, Xiao Ning was standing on a stone wall! Behind him was the cave he had just come out of!

This cave looks like a big crack created by the movement of the mountain!

And what shocked Xiao Ning the most was the scene in front of him!

In front of me, there is a huge sinkhole!

If Xiao Ning was to estimate, he wouldn't be able to estimate how big this sinkhole was, it might be more than three square kilometers in diameter!

There are a lot of grass and trees growing on the rock walls around the sinkhole, and judging from the scale and shape of this sinkhole, Xiao Ning feels that this is a bit like an abandoned mine!

Xiao Ning had seen such a sinkhole on TV before, and in some places, it even transformed the empty pit into a tourist attraction!

Xiao Ning took a small step forward, and some small rubble rolled down from where he was, making a rustling sound.

Xiao Ning touched his chest and took a step back, close to the wall.

The height of this place is more than ten meters high, and if you fall, you will become crippled if you don't die!

Xiao Ning looked up, and it was estimated that it was forty or fifty meters away from the top.

The distance of forty or fifty meters, if it is placed on flat ground, it will only take more than ten seconds to walk.

But if you want to climb forty or fifty meters at a vertical height, it's not so simple.

What's more, Xiao Ning doesn't have any climbing equipment, and he is not a professional climber, so it is difficult for him to climb up.

It is even impossible for him to climb up at all!

Since this can't go up, let's choose to go down!

After all, the distance from here to the bottom is only a dozen meters, and there are also some places to settle on the rock wall, as well as some grass and trees for Xiao Ning to grasp and provide him with support.

It depends on the situation, there are also a lot of rich resources at the bottom, staying here, either starving to death or dying of thirst, it is better to go to the bottom and fight!

Xiao Ning stepped on a suitable place to stay, firmly grasped some grass and trees clinging to the rock wall with both hands, and slowly crawled down.

Several times during this period, Xiao Ning almost fell, the stones around him were very wet and slippery, and his shoes couldn't hold on to them at all.

After a lot of effort, Xiao Ning finally came to the bottom!

The vegetation at the bottom is indeed extremely rich, and Xiao Ning also saw some fruit trees, which is good news for him, which can not only replenish the body's water, but also replenish vitamins!

The vegetation at the bottom of this sinkhole, in general, is a bird in the sky flying by, which just pulls the poop, and the undigested seeds in the poop fall here, and then take root and sprout.

Xiao Ning picked a few wild fruits, wiped them with his clothes, and then ate them.

While eating wild fruits, Xiao Ning observed the situation nearby.

Xiao Ning noticed that there were many small raised mounds in this place, very many, I am afraid that there are no less than a thousand.

"What are these things?" Xiao Ning couldn't tell what these small mounds were for.

Until, Xiao Ning inadvertently stepped on a hard thing.

Xiao Ning looked down and saw that it was a white flower, buried by the soil.

Driven by curiosity, Xiao Ning dug up the soil, and the whole picture of the thing was revealed.

"Dead man's bones!"

Xiao Ning was startled, it was a human thigh bone!

Xiao Ning instantly felt his scalp tingle, and a conjecture also appeared in his heart.

In order to confirm the conjecture in his heart, Xiao Ning found a wooden stick and turned over several mounds one after another.

In these mounds, Xiao Ning found human bones!

Obviously, these little mounds are all graves!

Inside this sinkhole, there is a huge group of tombs!

I found the dried corpse with a cross on his chest in the field they had cleared, and now I came across the graves.

In the past few days, have you with a dead man?

Syllable!

At this moment, Xiao Ning felt a palm fall on his shoulder, which made his hair stand on end, and his heart was drumming.
