Suddenly, the cold hairs all over my body stood up.

As soon as these hairs stand up, they can't be put down, and the whole person's heart is unconsciously cold.

The cry was very much like the mournful wail of a female ghost, and I could hear it very clearly, and it came from under the tomb where we were now.

Staring at the black blood that gradually surged up a little bit of bubbling, I panicked in my heart.

I don't know exactly what happened, but it's obviously not going to be a good thing.

There's definitely something underneath this burial chamber.

I quickly pulled out the bronze ancient knife, staring vigilantly at this black blood spring, and I could clearly smell that the smell of the previous ** was getting stronger and stronger.

My whole body was extremely nervous, although the gluttonous pattern on my hand did not react, but I heard a scream coming from under this ground, there is definitely some kind of evil existence under this earth.

Now the gluttonous pattern is not responding, probably because this thing is a little far away from us, plus there is a layer of black sand as an obstacle.

I took a few steps back, staring nervously at the fountain of blood, and I could clearly see that the speed of black blood surging from the fountain of blood was getting faster and faster.

When the blood gushed up, it was still burrowing into the black sand that was laying out nearby.

Because of this, even though the speed of the black blood returning upwards is relatively fast, the position of the black blood has not increased too significantly.

As the black blood continued to pour into the black sand laid underneath, I could clearly feel that the sand I was stepping on now had become much softer.

And the place I stepped on also had a tendency to sink slightly.

"Brother Li, be careful, the structure here is very weird!"

When I was vigilant, Wang Xun leaned against the wall and said with a solemn face.

I nodded, what Wang Xun said was not wrong, the structure here is indeed a little weird, through Wang Xun's previous excavation, there was a sound almost like something shattering, I already felt that something was not right.

I'll know the basic structure of the chamber at that time.

It should be that there is a layer of something similar to a stone wall under the black sand, which should not be very hard, and under the excavation of the folding shovel, it shattered in an instant.

It's just that I don't know, how did this black blood come up?

I'm confused about what the structure looks like underneath this floor.

Suddenly, I glanced at the wall on one side, and my whole face froze.

I see!

I stared at the wall in front of me, and it was clear in an instant.

The changes were very subtle, but I found something.

At this time, the walls around us are rising, and the ground under our feet is descending little by little.

Although the speed of the decline is not too fast, it is not easy to notice, but as long as you observe carefully, you can still find clues.

So I already understand the whole structure.

The junction between the wall and the ground is not connected, and the ground is not fixed here.

If I'm not mistaken, the material of the ground under the black sand is probably very special, and the sound from the previous knock is very weird, and I have never heard the sound of collision before.

I'm afraid the density of this ground is very low, much lower than blood.

In this way, the ground is filled with a lot of blood, and it can perfectly support the ground above.

In addition, the black sand is used as a layer to assist in stabilization, and the floor tiles are paved on top, so it is no different from a normal road.

But when it was excavated, Wang Xun dug a hole in this layer.

In an instant, the ground was like a leaky boat, and with the weight of the two of us and the bricks and black sand, it naturally sank little by little.

I have to say that this method is very exquisite, and the relationship between material and weight must be calculated quite exquisitely.

Just by breaking a hole, the ground will slowly sink.

This is the case for the calculation of density and buoyancy to a very deep degree.

Many low-density things, even if they have a big hole, can float on them, just like plastic foam, even if they are damaged, they can still float on the water.

According to my calculations, all these black sand and bricks are deliberately placed on them, and their purpose is probably to achieve a counterbalance with this buoyancy.

Such a design can be said to be wonderful.

Although the design is relatively simple, the implementation is very complicated, and it is difficult for ordinary people to notice anything wrong.

But now is not the time to admire, and after a little retraction, my face became solemn.

Even if the mechanics of this mechanism have been figured out now, it will be difficult to decipher.

It's impossible to fill this layer with material, and the layers here are all made of gravel, and the black sand is completely softened when it comes into contact with blood.

The use of grit for the sandwich here may be due to this aspect.

Even if it is filled with bricks, it is impossible to just press the top of the crack with bricks, and there are still gaps anyway, and it is difficult to block the blood.

"Brother Li, have you thought of any way? The blood level here is getting higher and higher! ”

Just as he was thinking, the blood was almost over the sand, and Wang Xun exclaimed with an unsightly face.

"The structure here has been roughly figured out, but I can't think of any way to deal with it, so I'll give you a brief explanation first, and let's think of a way together."

I responded and slowly walked in the direction where Wang Xun was.

As I walked, my face became more and more solemn, and I could clearly feel the sand under my feet getting softer and softer.

Judging from the current situation, I am afraid that the sand layer under my feet will not last long, and it will be completely soaked in black blood.

Immediately, I arrived at Wang Xun's side, and I told Wang Xun what I had guessed.

After Wang Xun heard my words, he pondered briefly after contemplating slightly.

He had only been thinking for less than a minute, and then his eyes suddenly lit up.

"If that's the case, it's going to be settled."

When Wang Xun spoke, I was suddenly startled, and then I saw Wang Xun take out a piece of linen cloth from the package, and there was also a bundle of leather cases.

Just when I didn't know what Wang Xun was going to do, Wang Xun quickly grabbed a handful of black sand, wrapped it in the rag, and tied the mouth of the rag with a leather case.

The whole rag and sand were combined to form a small sandbag, and then Wang Xun slowly walked to the edge of the blood spring and simply cleaned up the ground nearby. Read the latest chapters, stay tuned
