After a long time, I patted my chest, took a deep breath, calmed my fear and weirdness, and continued reading. Pen, fun, and www.biquge.info

The scene cuts back to the rift, where the masked leader leads the soldiers and some strange creatures into the rift, passes the spherical object, and continues down, the rift is so deep that it almost leads to hell.

As the climb progressed, all sorts of strange events occurred, first a person fell from the stone wall of the rift valley for no reason, and then some soldiers disappeared for no reason, and when they were found, they were embedded in the rocks, and the rocks around them had no traces of excavation, as if they had been swallowed by the rocks.

The climb seemed to take a long time, as I could see that the armor of the soldiers on the mural was slowly rusting, and finally turning into mud and peeling off from their bodies, and under the armor was a miserable white skeleton, still crawling down, as if it had been summoned by hell to legions of the undead.

"It's really not human!" I muttered to myself, "What's the foggy thing on the mural in front of me?" A demon crawling out of hell? ”

I immediately shook my head again, laughing at myself for being a little superstitious, this is just a mural, it is originally very artistic, and the things recorded on it seem to be a myth and legend that has not been handed down, the imagination of the ancients is still quite rich.

"What is the name of this legend? "Journey to the Center of the Earth"? "I'm such a person, although imagination and curiosity are the taboos of the tomb robbers, many times some tomb robbers can scare themselves to death, but I still can't control myself, fortunately, my psychological tolerance is quite strong, and some humor, very able to entertain myself, so as to ensure that at this time I will not feel lonely, nor will I be scared to collapse.

I turned my gaze to the next mural, and after passing through a huge cavern underground, it was as if they had arrived in another world.

The reason why I say this is because after passing through this cave, everything seems to lose color, the whole world becomes black and white, and the whole painting is divided into two distinct parts around the cave, which gives people a very strange feeling, this feeling, like a color printer printing a picture halfway through the print and suddenly running out of color ink.

The next few paintings tell about some of the activities of these skeleton soldiers in this world, not so much as activities, but rather tourism, and the murals show the scenes in this world in great detail.

There are many majestic buildings here, such as the Dragon Tower, the Treasure Hall, the pavilions, and a long bridge carved with skeletons, but there is not a single person, not even any living creatures.

I don't know if it's because the mural has been damaged to a certain extent, or because of the bad lighting, the whole picture looks very blurry, as if it is covered with a layer of fog.

What caught my attention the most was a stone arch in front of the bridge, which was taller than any building, and very regular, like a door frame, and in the center of the stone arch, there were three big characters written on it, although I didn't know these words, but as soon as I saw them, a thought immediately flashed in my mind - the underworld.

Sure enough, this rift valley leads to hell!

I actually felt a slight chill spreading up my heels, and reading this kind of thing in such a specific environment was like reading a horror novel alone in the silent midnight, although I knew it was fake, but I was still a little scared.

I turned around and looked up, at the end of my sight, there was a red candle flame, just now I only looked at the mural, I didn't notice how far I had walked, I looked at my watch, it had been half an hour, according to my speed of walking and looking, I should have walked out for two or three hundred meters.

Our Ruzhou terrain is relatively low, groundwater resources are also very rich, generally dig wells, down to four or five meters will come out of the water, this tomb is not steep, but from the top to the position I am in now, the vertical distance is at least fifty meters, but the inside of the tomb is still relatively dry, it seems that the waterproof work here is still good.

I collected my thoughts, rubbed my eyes and continued to look down, they continued to climb down the rift, what happened next was more boring, it was a boring climb, and what really caught my attention was this picture.

This picture is a section of a sphere, marked with many layers in many colors, at first glance, it looks like many rings set together, but when I look closely, I feel a chill to the bone, this is actually a section of the earth.

There is absolutely no mistake, this picture is exactly the same as the one in the geography textbook I learned in high school, the lithosphere, the asthenosphere, the upper mantle, the lower mantle, the outer core, the inner core, everything, there are many small signs next to the map, with a very strange text, a bit similar to the earliest bird seal of the Western Zhou Dynasty, but it seems to be more ancient than it.

Could it be that the ancients knew thousands of years ago that the earth was round? And they already had a complete understanding of the internal structure of the Earth at that time? It's impossible!

I began to try to recall what I knew, and the Greek mathematician Pythagoras had already proposed the concept that the earth was a sphere in the sixth century BC, but the ancient Chinese had always believed in the doctrine of "the sky is round and the earth is round".

This can be seen from many unearthed ancient books and objects, the most famous is Zhang Heng's armillary sphere, but it is not excluded that there are some more advanced scholars who support Diyuan's theory, Lao Zhao once stole a volume of ancient books of the Tang Dynasty, and it is impossible to verify who the author is, but what is written above is a very interesting question, roughly like this - the further north you go, the higher the North Star; The further south you go, the lower the North Star becomes, and you can see some new stars that you won't see in the north.

But how to explain the internal structure of the earth? It should not be said that it is the crystallization of the imagination of the great working people of our country in ancient times, and I will not believe that what some people imagine out of thin air will be so consistent with the facts measured by precision instruments.

Oh my God, what did I see, or what did the person who painted this mural want to express to me?!
