I suddenly felt the hairs all over my body stood up.

As soon as these hairs stand up, they can no longer let go of them, and their hearts are unconsciously cold.

The scream was extremely like the shrill wail of a female ghost. I could hear it very clearly. The sound came from below the tomb where we are now.

Staring at the little bit of black blood that was gradually surging up, I felt very panicked.

I don't know what happened, but obviously it won't be a good thing.

There is definitely something under this tomb.

I quickly pulled out the bronze ancient sword and stared at the black blood fountain vigilantly. I could clearly smell the previous scent of the scent became stronger and stronger.

I was extremely nervous. Although the Taotie pattern on my hand didn't react much, I heard a scream from the ground. There was definitely some evil existence under the ground.

The Taotie pattern has not responded now, maybe because this thing is a little far away from us now, and there is a layer of black sand as a barrier.

I took a few steps back and stared at this blood fountain nervously, and I could clearly see that the black blood surging from the blood fountain became faster and faster.

As the blood surged up, it was still drilling into the black sand that was laid out nearby.

It is because of this that even though the black blood returns upwards relatively quickly, the position of the black blood does not increase significantly.

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

And the place I stepped on also tends to fall slightly.

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

When I was alert, Wang Xun pressed tightly against the wall and spoke with a solemn expression.

I nodded. What Wang Xun said was right. The structure here was indeed a bit weird. When Wang Xun dug before, a sound that almost happened when something broke, and I felt something was wrong.

I will still know the basic structure between the tombs.

There should be a layer of something similar to a stone wall under the black sand. This stone wall should not be very hard. It broke instantly under the excavation of the folding shovel.

But I don’t know how this black blood came about?

I was confused about what the structure under this layer looked like.

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

I see!

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

Although the changes were very subtle, I still found something.

At this time, the surrounding walls were rising, and to be precise, the ground we were stepping on was descending little by little.

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

In this way, I already understand the entire structure.

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

If it is correct, the ground material under the black sand would probably be extremely special. The sound from the knocking before was very strange. I have never heard of the collision sound before.

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

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

In addition, black sand is used as a layer of stability, and floor tiles are laid on it, so walking is no different from a normal road.

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

In an instant, the ground was like a boat with water leaks. In addition, the weight of the two of us and the bricks of black sand naturally sank down 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.

If you just break a hole, the ground will slowly sink.

This should reach a very deep level for the calculation of density and buoyancy.

Many things with lower density can float on them even if they are broken, just like plastic foam. Even if they are broken, they can still float on the water.

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

Such a design can be said to be wonderful.

Although the design is relatively simple, it is very complicated to implement, and it is difficult for ordinary people to find something wrong.

But now is not the time to admire. After slightly regaining the spirit, my face became solemn.

Even if the operating principle of this mechanism has been solved now, it is difficult to crack.

It is impossible to fill this layer of material. All the interlayers here are made of gravel, and these black gravels will completely soften after encountering blood.

The use of gravel in the mezzanine here may be because of this aspect.

Even if it is filled with bricks, it is impossible. Just pressing the top of the crack with bricks is still a gap, and it is difficult to block blood.

"Brother Li, have you thought of any solution? The blood spots here are getting higher and higher!"

Just as he was thinking, his blood was almost filling the sand layer, and Wang Xun exclaimed with an extremely ugly expression.

"I have roughly understood the structure here, but I can't think of any way to deal with it. Let me briefly explain it to you first and think of a solution together."

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

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

Judging from the current situation, the sand layer under your feet may not last long and will be completely stained with black blood.

I immediately arrived at Wang Xun and told Wang Xun what I guessed.

After hearing my words, Wang Xun condensed his mind slightly and thought briefly.

He thought for less than a minute, and his eyes lit up suddenly.

"If this is the case, things will be easy to resolve."

While Wang Xun spoke, I was suddenly shocked, and immediately saw Wang Xun take out a piece of linen from the package and a bundle of leather hoods.

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

The whole rag and sand combined to form a small sandbag. Then Wang Xun slowly walked to the edge of the blood fountain and simply cleaned the nearby ground. Please pay attention to the latest chapters
