However, in this place where the tomb is getting deeper and deeper, the deeper the position on the ground, the slower the air flows.

Some of the decaying gases formed in the tomb after thousands of years are inert, and these gases often accumulate at the bottom.

In this case, the air flows very slowly, and it can even be said that no one has walked faster.

The road downhill here is much deeper than the tomb I have passed in the past. I don’t know if it is because of nature or if it is buried very deep.

I glanced at my waist slightly. There were three lights on the waist that looked like a walkie-talkie. When I saw that the lights on it were green, I didn't slow down.

This thing is an air detection device. If the green light on it is on, it means there is no problem with the air.

If the yellow light on it is on, it means that the oxygen content is 5% to 15% lower than normal, and the machine will usually alert you at this time.

If the red light above is on, it means that the oxygen content in the air is very low, far lower than that in normal air, and it is even enough to be a life-threatening time.

Or maybe there is some toxic substance in the air, and a red light will appear when the machine detects it.

When a red light appears, it is not just an alarm once, but a warning will be issued several times.

I saw this thing before when Mr. Qian and I were in the tomb. Later, I became more careful and bought one.

But every time I get to the tomb, someone brings such instruments, and my machine has never come in handy.

Such instruments are most suitable for use in deep burial tombs.

Due to injuries on my body and a box behind me, I was not walking too fast, about five or six meters per minute, and I had to rest every time I walked for nearly five minutes, and the speed was much slower than before.

This tomb passage, which is about 100 meters in total, actually made me walk for half an hour.

Now I have completely known how much the injuries I have recovered. It is already very good that I can barely move to this level.

Now, as long as I take a step, I feel like I'm pulling the wound, and my whole body trembles involuntarily.

Such a situation is really helpless.

After a while, I finally walked to the end of this not-too-long tomb passage.

The moment I walked to the end of the entire tomb passage, I suddenly breathed a sigh of relief and instantly collapsed on the ground.

The moment I stepped out of the tomb passage, I didn't even have room to observe the surrounding scenery.

The whole person can be said to be extremely tired.

Only when I was completely sitting on the ground did I start to look at the scene around me.

There is a square room around it, and the entire room is not much different in length, width and height.

It looks like a complete cube.

The floor is covered with floor tiles, and each floor tiles are square, and the color on the surface of the floor tiles is different.

If the colors are classified, there are two kinds of floor tiles in this room, one of which is whiter in the color, while the other is darker in the color.

Beneath the light of the flashlight, you can clearly see the difference between the two.

It seems that these conditions on the ground are not that simple, and these bricks of different colors look very disorderly arranged.

Except for the small stone platform in the middle of the room, the whole room is full of paved with such floor tiles.

My eyes gradually narrowed. The stone platform in the tomb was not too far away from me. I vaguely saw something standing upright on the stone platform.

When I narrowed my eyes into a slit, I could clearly see a coffin standing on the stone platform in front of me.

This coffin was completely placed upright, just like the coffin of the Egyptian pharaoh in the museum seen on TV.

This is not a horizontal layout, but a way to place books in the tomb. This is the first time I have seen it in the tomb.

This should be of some qualities.

I stared at the coffin erected in front of me, but there was very little information about this in my mind, and I didn't know what the meaning of such a placing was.

But the only thing that is certain now is that something is wrong with the tomb in front of you.

Whether it is the arrangement of the coffins or the floor tiles on the ground now, they are completely different from the style I have seen in the past.

The floor tiles in front of me are probably mechanisms. I squatted down slowly and first looked at the brick closest to me.

The four corners around the floor tiles are very accurate, and the gaps between the bricks are not large. Under normal circumstances, even a blade cannot be inserted into it.

My brows frowned gently. If the gap between the bricks is so small, would it really not have any impact if it was a trigger mechanism?

The gap between each other is too small, and I am afraid that they can contact and rub each other, so it will be difficult for the mechanism to touch it.

My hand slowly touched the surface of a brick. The brick was completely made of stone, and the material did not look too special.

At the moment of contact, you can feel that the smoothness on the surface of the stone is indeed extraordinary.

With the light of the flashlight, you can even see the reflection on the bricks, and the entire brick is like a mirror.

Just this polishing process can be said to be quite impressive.

There is no trace on it, and it really feels like a mirror.

So that's it!

Almost at this moment, I came back to my senses. If the entire surface of the brick was polished like this, it would be possible that the gap between the trigger mechanisms was very narrow.

After all, the friction force on the surface can be said to be extremely low. No matter how small the gap is, it should be able to touch the mechanism when it encounters external forces.

Almost at this point, I can already be sure that there is at least 80% chance that the floor tiles in front of me are hidden.

If there is no hidden mechanism, there is absolutely no need for such treatment on the surface of these floor tiles.

If it is just a wall as a whole for polishing, it is understandable, but now it is floor tiles one by one.

In order not to affect the overall aesthetic appearance, it is absolutely impossible to polish a whole piece of floor tiles together once polishing.

The most likely thing is to polish the floor tiles one by one separately, which can be said to be very long.
