Chen Fan cautiously looked at the rock wall and did not sneak in rashly.

The passage behind the waterfall is very narrow, and it doesn't seem to be a natural formation, when his eyes are locked at his feet, Chen Fan immediately saw a "clay urn"-like vessel, the vessel has been dried and corrupted, and it will be broken with a finger touch, Chen Fan cautiously removed his toes, no longer touching anything here, and then silently squinted his eyes, but found some mural-like lines on a damp wall.

"How can there be a mural here?"

Chen Fan's heart was shocked, and he hurriedly walked towards the mural, but unfortunately the age of the mural was not known for how long, it had already dried, and it was driven by the air flow of Chen Fan's movement, and the surface of the mural formed a strong powder, and before he could see the content on it, it had already peeled off.

"It's incredible!" Chen Fan's eyes flickered slightly, and his heart was extremely shocked.

The appearance of the mural shows that there were indeed traces of human activities here, after all, the earliest civilization of mankind was transmitted through relief totems, but this is obviously a different dimension, the ruins preserved in ancient times, how can there be murals left by human ancestors?

Chen Fan couldn't figure it out even if he wanted to, but he faintly felt that the appearance of this mysterious space must have some kind of connection with the real world, maybe if he continued to search, he would be able to find out the reason why the Blue Star World was attacked by monsters.

Thinking of this, Chen Fan immediately quickened his pace and continued to walk towards the depths of the cave, not long after walking, a dry breeze began to pour through the wet cave wall, and a warm breeze blew on his face, which was exceptionally warm and peaceful, and in the depths of the cave wall, there was a faint glow, and the cave was no longer so dim.

"It seems that this valley is indeed unique!" Chen Fan's heart sank slightly, a large number of doubts poured into his mind at the same time, and after thinking for less than two seconds, Chen Fan moved his steps again, and quickly walked towards the place where the light emanated, and with the violent approach, a new world suddenly appeared in front of him.

If he hadn't seen it with his own eyes, Chen Fan would never have been able to believe what he saw.

Outside the cave, is a primitive atmosphere of the ruins of the city, the whole body of the city is made of black boulders, the vicissitudes of the ancient atmosphere suddenly come to the face, in the depths of this ancient city, there is even a huge cone-shaped pagoda, its architectural pattern is unprecedentedly huge, far better than the mysterious pyramid of the blue star world.

The pagoda is also made of black walls, its height is about fifty or sixty meters, and the base is equivalent to the size of a football field, smooth plane, without a trace of creases, not even traces of stone splicing, like a whole.

Countless years of precipitation, so that it is full of mysterious simplicity and heaviness, and around the bottom of the tower, there are all kinds of low buildings, these buildings are all pyramid-shaped, and the pagoda is no different, but no matter the pattern or space, it is much smaller than the normal human world buildings.

"This is ......" Chen Fan's heart shook violently, and he felt a chill in his back, and goosebumps appeared.

Chen Fan even suspected that he had come to Egypt, because the giant stone pagoda in front of him was too small with the pyramids left by ancient Egyptian humans thousands of years ago, not only the shape was the same, the structure was similar, but what made Chen Fan puzzled was the number of these stone pagodas, nearly a thousand pagodas accumulated here, looking at it from afar, it looked like a giant burial pit.

"If the Blood Alien didn't lie to me, then the space here was formed at least 100,000 years ago, but inside the space, there are so many buildings with the same pattern as the pyramids of the Blue Star World, could it be that hundreds of thousands of years ago, there were really humans here?"

Chen Fan felt dazed for a while, but this state did not last long, and was soon replaced by shock because of the new discovery.

The ancient city covers an area of nearly hundreds of thousands of square meters, and around the city, there are four or five giant peaks rising from the ground, these giant peaks are like pillars supporting the sky, surrounding the entire city impermeable, like a solid city wall!

Standing at Chen Fan's angle, he couldn't see where the end of those "pillars" was, these peaks, like pillars that plunged straight into the sky, stretched all the way to the nine heavens, more like a mysterious passage!

"It's so strange, how did such a high mountain come to be, and why are there human ruins here?" Chen Fan silently raised his head and stared at the line where the giant peak met the sky, and in the depths of a hazy sea of clouds, a huge celestial body could be faintly seen.

The spherical surface of the celestial body shows countless irregular "depression" lines, like one giant crater after another, it is very close to the ground, and from a distance, it looks as if it is being held up by these ancient peaks!

"It's ...... The moon? Chen Fan was in a trance, he looked blankly at the uneven marks on the surface of the celestial body, and a conjecture clearly surfaced in the depths of his mind.

These mottled concave and convex lines were extremely close to the pictures of the surface of the moon that he had seen in his previous life, and he even suspected that the huge celestial body was a projection of the moon at all, but shouldn't the moon hang high in the real world, why should the moon be seen here? And so close, so clear!

Chen Fan was completely shocked and speechless, he looked around, constantly searching for valuable things, and soon, he saw a place less than five hundred meters away from him, showing a huge platform, on the platform stood hundreds of black stone pillars with log structures, the stone pillars were like a rainforest, intersecting and folding with each other, looking very mysterious.

Chen Fan moved his footsteps and slowly approached the forest sea formed by the stone pillars, and soon, the stone pillars with the thickness of the stone pillars were presented in front of him, the stone pillars were also made of black, and the mottled surface of the stone pillars was carved with dense reliefs, and the relief markings were shallow, and they had lost their original luster in the decay of the years, but some content could be vaguely seen.

The images on the relief are some creatures with large heads, but limbs and torsos that are extremely similar to humans, and these creatures are almost indistinguishable from humans, except that there is an extra vertical eye on the door of the head.

Three-Eyed Wictan!

Chen Fan was shocked, the human beings depicted on the relief, both in appearance and body proportions, were extremely similar to the humans in the Blue Star World, it may be aliens, but it may also be the human ancestors who have lived in the Blue Star World for hundreds of thousands of years.

The relief depicts these three-eyed humans fighting against a monstrous flood with a giant axe and spear in their hands.

In the depths of the flood, there were many pairs of evil eyes, and since the body parts of these eyes were not drawn in the relief, Chen Fan could not tell what kind of monster it was.

If all the reliefs are connected, it is a terrible apocalyptic scene, the ancient human world, suffered an unprecedented flood since ancient times, and there were all kinds of flood beasts in the flood, encroaching on the human home, these three-eyed people in order to protect their homeland, and the monstrous beasts in the flood fought fiercely, and finally the flood subsided, and the three-eyed people were completely extinct.

The place where the flood appeared was a broken sky, and a huge crack appeared on the black sky, and the monstrous flood was vented from those cracks, and around the crack, there was a back figure with a human head and a snake body, holding five stones of different colors, trying to fill the broken sky.

"Wait...... The flood, the moon, and the five-colored divine stone that fills the sky, this is the ......" Chen Fan seemed to think of something, his pupils suddenly dilated, and the whole person was terrified.

He muttered, "Could it be that the legend of Nuwa mending the heavens is true...... These things that only exist in myths have really appeared in the Blue Star World! ”
