Don't ask Tang Feng how he knows that the black dot is the place occupied under his feet, because Tang Feng can't tell why, it's just a kind of intuition.

The left half of the mural is painted with these two pictures, and the right half, which is near the tunnel leading to the northwest, is also made up of two pictures.

The first image is obviously connected to the second one, because the first image on the right side starts from the black dot, and a dotted line runs north along the Andes Mountains until about the Mexican Altiplano.

The dotted line runs north through Peru, Ecuador, Colombia, and other countries in Central America, and finally comes to an abrupt end at the Mexican plateau. The country and direction of this dotted line made Tang Feng immediately think of the famous South American Tunnel.

In fact, the South American Tunnel has not only been discovered in Ecuador, Colombia, and Mexico, and the mysterious underground tunnels have been discovered, and most importantly, although these tunnels are intermittent, if these tunnels are connected, a large tunnel along the Cordillera from Mexico to Chile will suddenly take shape.

Could it be that this picture is the Great South American Tunnel?

If this picture is true, then it is almost certain that the mysterious South American tunnel should be from Mexico in Central America all the way to Antarctica

This distance is definitely more than 10,000 kilometers, which is much longer than the length of more than 4,000 kilometers of the South American Tunnel. But even now, humanity has not fully understood where the South American Tunnel leads and how it was formed, so this incorrect inference of humans is nothing.

Now it seems that this tunnel is most likely excavated by this shape civilization. Otherwise, Juan. Dr. Moritz would not have found so many items in the underground halls of the Great South American Tunnel in Ecuador that clearly did not belong to Earth's civilization.

In this picture, there is also a dotted line that runs from the black dot to the east, and this dotted line goes all the way to the east coast of Brazil. This dotted line made Tang Feng blink involuntarily, because no matter how you look at this dotted line, it looks like the tunnel he has walked through in the past two days.

Although this map does not show the terrain elevation or the like, the terrain of the whole of South America is vividly depicted, and Viamontes, who fell into the underground river, looks like it from this map. It's right next to this dotted line

At this time, Tang Feng had a comprehensive understanding of the South American Tunnel. If this picture is true, then the Great South American Tunnel, which has puzzled mankind, is nothing at all.

This tunnel that runs through the entire South American continent and even reaches South America is not one, but two, one of which crosses the entire South American continent horizontally to the east in the middle of the South American continent, but I don't know that the group of aliens had to dig such a tunnel similar to a "T" shape, dividing the entire South American continent into three parts.

But vaguely, Tang Feng seemed to feel that the group of aliens back then seemed to be looking for something.

Of course, this is just a vague guess by Tang Feng. However, when Tang Feng saw the second picture on the right half, Tang Feng only felt that his brain was "buzzing".

Without him, because the thing in the middle of the second picture is too familiar to Tang Feng. It was a hexagonal earthy yellow stone, identical in color and shape to the core of the star. And all the lines in these pictures are that kind of black, but this hexagonal earthy yellow stone is not known to be painted in what color. I don't know how many years have passed, but it still retains that vivid earthy yellow.

"How can there be a star core here?" There is hardly any suspicion. Tang Feng can be 100% sure that the stone painted on this petroglyph is the star core, and it is definitely the star core on his body!

Tang Feng only felt a chill on his body, and an emotion that was almost desperate suddenly wrapped Tang Feng's whole person.

"Why is that? Why would anyone be able to draw a star core? Could it be those aliens? Or maybe those aliens came to Earth to look for a star core? Tang Feng only felt that his brain had turned into a pot of paste, and he seemed to grasp something vaguely, but in the blink of an eye, he couldn't grasp anything.

Took a long breath. Tang Feng settled down and began to look at the second picture carefully.

All the attention just now was attracted by the star core pattern, so that Tang Feng didn't see what this picture was at all, and now after looking at it carefully, Tang Feng felt that he suddenly had a feeling of being sudden.

This second picture is also quite simple. However, the content is not simple at all, because on this map, a dotted line extends westward from the black dot, across half of the Pacific Ocean, all the way to the Australian mainland. And the pattern of the star core is located on the Australian continent.

Seeing this, Tang Feng finally understood what the little clue that he couldn't grasp just now was.

The four pictures are actually telling a story, to be precise, it should be telling the story of an alien who came to Earth to find a star core. The first picture is supposed to tell about the aliens coming to the earth, and the second picture is about the aliens coming to the earth and descending on the Antarctic continent. The third picture should be about the process of this group of aliens looking for the core material on the earth to condense the star core, otherwise the aliens would not have dug such a long tunnel. As for the fourth picture, it shows that the aliens finally succeeded in condensing the star core in Australia!

If you look at these four pictures, it tells such a simple story. But Tang Feng felt that there seemed to be something wrong with this story.

When Tang Feng was buried underground, the main program once told Tang Feng very clearly that they came to the earth after crossing a distance of tens of millions of light years, and used the core material of the earth to condense into a star core, and after condensing into a star core, they were ready to start the first mining operation, but the first mining encountered crustal changes such as earthquakes, resulting in the destruction of the spaceship, and then they have been trapped in Australia.

In other words, the first owner of the star core should have been a star core condensed in Australia, and then it was trapped in Australia before it reached other continents. So how did the star core pattern on this petroglyph come about? (To be continued......)
