But where the tomb gets deeper and deeper, the deeper it is from the ground, the slower the air circulates.

Some of the decaying gases that have been formed in the tomb over thousands of years are inert, and these gases tend to accumulate at the bottom.

In this case, the air flow is very slow, and it can even be said that no one has walked fast.

The road on the downhill side was much deeper than the tombs I had passed before, and I don't know if it was due to nature or because it was buried very deep.

I glanced at my waist, and there were three lights on my waist, which looked like walkie-talkies, and when I saw that the lights on it were green, I didn't slow down.

This thing is an air detection device, and if the green light on it is on, it means that there is nothing wrong with the air.

If the yellow light on it is on, it means that the oxygen level is 5 to 15 percent lower than normal, and the machine usually gives an alarm at this time.

If the red light on it is on, it means that the oxygen content in the air is very low, far lower than the oxygen content in normal air, and even enough to threaten life.

Or maybe there is some kind of toxic substance in the air, and if it is detected by the machine, a red light will appear.

When a red light appears, it is not just one alarm, but several warnings.

I had seen this thing when I went to the tomb with Qian Lao before, and then I also had a heart and bought one.

It's just that every time I go to the grave, someone carries such a device, and my machine has never come in handy.

Such an instrument is suitable for deep burials.

Due to the injuries on my body and the fact that I was dragging a box behind me, I didn't walk too fast, about five or six meters a minute, and every time I walked close to five minutes, I had to take a break, and the speed was much slower than before.

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

I know exactly how far I've recovered from my injuries, and now I'm barely able to move to this point, which is pretty good.

Now, as long as I take a step, I feel like I have pulled the wound, and my whole body trembles involuntarily.

In a situation like this, it's really quite helpless.

After a short time, I finally came to the end of this not too long tomb road.

The moment I brought the entire tomb to the end, I suddenly breathed a sigh of relief, and my body collapsed to the ground in an instant.

The moment I stepped out of the tomb, I didn't even have the slightest room to observe the scene around me.

The whole person can be said to be extremely tired.

The moment I sat down on the ground, I began to look around me.

All around this is a square room, and the whole room is not much different in length, width, and height.

It looks like a complete cube.

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

If color is used as a classification, there are two types of floor tiles in this room, one of which is whiter and the other is darker.

Under the light of a flashlight, the difference between the two can be clearly seen.

It seems that these conditions on the ground are not so simple, and the bricks of different colors seem to be arranged in a very disorderly manner.

The whole room, except for a small stone platform in the middle, is full of such floor tiles.

My eyes narrowed, the stone platform in the burial chamber was not too far away from me, and I could vaguely see something standing 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 is completely upright, just like the coffin of the Egyptian pharaoh seen in the museum on TV.

This is not a horizontal arrangement, but a way of placing the book upright, and this is the first time I have seen it in the tomb.

This should be something to be special about.

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

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

Whether it is the arrangement of the coffins or the tiles on the floor, they are completely different from what I have seen before.

The floor tiles in front of me were most likely mechanisms, and I slowly crouched down and looked at the nearest brick first.

Around this floor tile, the four corners are very precise, and the gap between the bricks is not large, and under normal circumstances, even a blade cannot be inserted.

His brows furrowed slightly, if the gap between the bricks was so small, if it was a trigger-type mechanism, would it really not have an effect?

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

The hand slowly touched the surface of a brick, which was completely stone, and the material didn't seem to be too special.

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

You can even see the reflection on the bricks by the light of the flashlight, and the whole brick is like a mirror.

This polishing process can be called quite good.

There is not a trace on it, and it really feels like a mirror.

So that's it!

Almost instantly, I came to my senses that if the entire surface of the brick was polished like this, it would be possible for the trigger mechanism to have very small gaps between each other.

After all, the friction on the surface can be said to be extremely low, even if the gap is small, it should be able to touch the mechanism under the action of external force.

Almost at this point, I was already sure that there was at least an 80% chance that the floor tiles in front of me had hidden mechanisms.

If it weren't for the hidden mechanism, there would be absolutely no need for such a treatment on the surface of these floor tiles.

It would be understandable if it was just one wall as a whole, but now it is a piece of floor tiles.

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

Most likely, the floor tiles are sanded separately one by one, which can be said to be a very long time.
