Shen Rui followed Lao Pan's hope, and sure enough, there was a gap at the bottom of this huge underwater pyramid, square, ten meters wide, and ten meters high, judging from the location and structure, it seemed that it was deliberately left when it was built in the pyramid.

After thinking about it for a while, Shen Rui manipulated the pyramid to dive down to a depth of 1,723 meters, and then slowly moved towards this entrance.

The water pressure was close to the limit of the Seahorse, and everyone was nervous, and they didn't even dare to breathe in the atmosphere, and there was an irritating squeak in their ears, which was the huge pressure of the sea water squeezing the hull of the submarine.

The Seahorse entered the entrance without incident, slowly beginning to float upwards, eventually appearing in a pool.

It turns out that there is also air inside the pyramid, and the air inside the pyramid balances the pressure of the seawater, creating a stable space in the deep sea.

As for this pool, it seems to be a deliberately set dock, and there are even stone pillars on the shore where the submarine can be tied with a cable.

Shen Rui and the others carefully opened the sealed door, entered the inside of the pyramid with great surprise, and looked at the magical underwater world in a daze.

Ye Wuxian squatted on the ground, carefully observed the ground with a spotlight, and said in a deep voice: "This is the Black Yao Volcanic Rock, the texture is extremely strong, the volume of each boulder is three meters by three meters, and the weight is estimated to be three hundred and fifty tons. ”

Shen Rui was stunned and said in surprise: "Human beings have the ability to transport such huge stones and build pyramids on the bottom of the sea?" ”

Ye Wuxian shook his head and said: "It's difficult, what's even more strange is that the cracks of these boulders are filled with a substance similar to cement, but the strength is not known how many times that of cement." ”

After that, he took out a handful of German-made **, and vigorously pried the white sealing material between the boulders, the knife was about to bend, but these cement-like substances did not move at all.

"Ultra-prehistoric civilization." Ye Wuxian said in a deep voice: "There is no doubt that this underwater pyramid is very old, but the technology used cannot be done even with our technology today, if it is not a product of a super-prehistoric civilization, it can only be inferred that he belongs to aliens." ”

Shen Rui stuck out his tongue, the existence of super-prehistoric civilizations is still a mystery to this day, and the more common example is the Mayan civilization in South America.

As we all know, the Mayan civilization belongs to the nature of the barbaric agricultural civilization, the ancient Maya were very bloody, at every turn to take out people's hearts to sacrifice to the sky, slaughter thousands of people and throw them into caves to worship the gods.

But it is such a wild and barbaric civilization that has incredible astronomical technology, and they have established an accurate calendar by observing the movement of the sun and the moon, and draw accurate star maps.

This is a super-prehistoric civilization, obviously a group of barbaric primitive people, but to a certain extent have mastered the technology comparable to modern people, as for the reason, no one knows, many scholars suspect that the Maya mastered such advanced technology because aliens once patronized and taught them all kinds of skills.

Even more legendary than the Mayan civilization is the Atlantean civilization of 10,000 BC.

Legend has it that Atlantis was a people of the god of the sea, living in an incredible, miraculous city, mastering astronomy, geography, mathematics, mechanics, music, and other extremely advanced civilizations, and they even had the ability to build airplanes.

You know, even in modern times, there are not many countries that have the ability to build airplanes, let alone such a distant age as 10,000 BC.

Obviously, this underwater pyramid is the remains of a super-prehistoric civilization, as for who established it and which civilization it belongs to, Shen Rui and they don't know.

Shen Rui swiped his finger on the ground a few times, "The landing point of the Holy See is opposite us, now we need to go through the center of the pyramid and figure out what exactly they are going to do, it is best to be able to save Sir Bruce from them." ”

Ye Wuxian and Lao Pan nodded, so the three of them left the landing site and walked along the promenade, trying to reach the other side of the pyramid.

The underwater world was extremely cold, but fortunately, Shen Rui and the others had been prepared, and they all wore thick jackets.

The road in the pyramid is like a labyrinth, Ye Wuxian activated his positioning equipment, but found that all the electronic equipment was out of order, Shen Rui walked in front, his perception was relatively strong, and he might be able to lead everyone through these complex lanes.

"Look, are these the legendary mermaids?" Shen Rui raised the glow stick in his hand and lit up a wall.

Ye Wuxian and Lao Pan looked at the light, and saw that the strokes on the wall were really bizarre, a group of women with the upper body of a human and the lower body of a fish, fighting with a group of warriors with dolphins on their feet.

Judging from the frescoes, the battle took place on an island with lush vegetation and a majestic giant city in the background, with high walls and a huge black tower that reached to the sky.

The mermaids depicted in the mural are not only not beautiful at all, but can even be described as hideous, with pointed ears, gills on their necks, and their mouths are all as sharp as knives when they open their mouths, and they pounce on the warriors riding dolphins and tear them up, biting through the warriors' bellies and tearing out the internal organs crazily.

Countless literary works in human history, TV and movies, portray mermaids as cute and well-behaved creatures, they are not only beautiful, but also loyal to love, and do not hesitate to break their bones in order to fall in love with the humans they like.

And the mermaids on these murals are simply a group of banshees, with bulging eyes, like the eyes of a dead fish, and the form is extremely crazy, which makes people shudder at the sight.

"I don't want to run into a creature like this." Lao Pan shook his head and said seriously.

Ye Wuxian didn't say a word, took a serious picture of these murals with his camera, and said to himself: "According to some historical records, the road of human evolution has not been smooth sailing, although most human beings have come out of the jungle, started agriculture, and become our ancestors, but there are still some human beings who have embarked on a completely different path from what we have today. ”

"Some human tribes have evolved a marine survival system because they have lived by the sea for a long time, and they can live under the sea like fish, and they are called fish people, which is also the prototype of mermaids.

"The sailors in the fleet believed that on the night of the full moon, the mermaids would approach the side of the ship and use their singing and beauty to confuse the lonely sailors, and once the sailors fell into the trap set by the mermaids, they would be torn apart and eaten by them."

"So these murals are nothing special, it's just different from the mermaids we see in cartoons, and in comparison, it's still the evil mermaids that are closer to historical archetypes."

"Having said that, I care more about the soldiers who ride dolphins, it seems that they have the ability to communicate with dolphins and be able to control sea creatures, which is quite similar to Shen Rui, and maybe it is also a kind of mind control technique."

"The other is the Tower of Babel in the distant city, according to historical records, the Tower of Babel is supposed to be a symbol of the ancient Babylonian Dynasty, how did it come to the coast? It looks like it's still tropical, and the vegetation is luxuriant. ”

"Maybe it's just another kind of legend, the people who carved the mural depicted a war that we didn't know about, a battle between humans and fish-people, based on the legends of their people."

Shen Rui nodded slightly, everyone knew that Ye Wuxian was very knowledgeable, and if he was the main speaker, I am afraid that he would not be able to finish it in three days and three nights, but now is obviously not the time to chat, it is more important to quickly rescue Bermuda expert Bruce from the hands of the church.

After walking not far forward, Shen Rui's face suddenly changed, and he gestured for everyone to stop.

"Listen, it is like a voice." Shen Rui pricked up his ears and whispered.
