However, this sacrifice wears a rare yellow mask, and also holds a yellow scepter in his hand, Hu Xiaodao is a bit strange, and the murals here only have three colors: white, dark red and black, why is there yellow?

Hu Xiaodao reached out and touched it, feeling that the yellow quality was smoother than other colors, because it was close, and the miner's lamp on his head actually shone a little on the yellow paint.

Hu Xiaodao put down the backpack and stepped on it, lying on the wall to take a closer look, this yellow paint is actually gold!

After discovering that it was gold, Hu Xiaodao noticed that the whole pattern was not only the mask and the scepter in his hand, but also the bronze medal hanging on the chest of the sacrificer, and the bone chain on his hand, all made of gold.

The only pity is that these are not carved, but painted with gold dust.

Continuing to look at the third one, the style of painting is much simpler, from a dozen people gathered next to the sacrifice at the beginning, and now there are about thirty people.

The difference is that some people carry horsewhips, some people carry machetes and spears, although the clothing is similar, but there is still a clear difference when you look closely, at least everyone's clothing is almost different.

This point conflicts with Hu Xiaodao's cognition.

Even thousands of years ago, people were already very concerned about the structure of the army, and it was impossible for people to dress differently in the same country.

If it appears by force, then there is only one end - this is the coalition army.

From the perspective of the country, Hu Xiaodao really doesn't understand what these 30 or so coalition forces represent, could it be that these 30 or so people represent not individuals, but more than 30 tribes?

This is highly likely.

Nowadays, there are 13 countries and regions in the whole of South America, with a total area of 17.8 million square kilometers, and if a tribe with hundreds of people in ancient times, more than 30 tribes can only be regarded as a very small force.

However, in the fourth picture, Hu Xiaodao looked at it with a tight heart.

In the picture is a monster with a human head and an octopus body, and judging from the scale of the picture, each tentacle of this octopus is about three to five meters long.

At the same time, the tentacles of the octopus also grasp different prey, including humans, jaguars, and monkeys.

The human-faced octopus is surrounded by several Amazonian piranhas, and their sharp teeth and three rows of spikes above and below their bodies show that they are the real overlords of the vast sea, and even the octopus that holds its prey runs away from them, not daring to annoy them.

There are dozens or hundreds of murals like this, Hu Xiaodao naturally didn't have time to look at them one by one, but just took a general look, it is worth mentioning that Hu Xiaodao also saw the picture scroll about mermaids.

The secular perception is that the mermaid is bounded by the waist, the upper body is a beautiful woman, and the lower body is a beautiful fish tail covered with scales, and the whole body is both seductive and easy to escape quickly.

They have no soul and are as merciless as the sea; Voices, like their appearances, are often deceptive; A combination of seduction, vanity, beauty, cruelty, and desperate love.

The familiar image of the mermaid comes from the beautiful mermaid Lorele, which is often mentioned in German legends and poems.

She would often appear on the banks of the Rhine when it was dark, and with her cold and poignant appearance and mournful singing, she would distract the passing boatmen and disorient them, and finally sink to the bottom of the river.

In modern science, female dugongs are often mistaken for "mermaids" because they occasionally have the habit of carrying their young to the surface of the water to breastfeed.

However, the picture that Hu Xiaodao saw may have been painted thousands of years ago, showing a group of men and women, dozens of people with tails, exchanging various fish and squid from the indigenous people of the time for wooden combs.

In 1962, a probe ship carrying scientists and military experts captured a human child off the coast of Cuba with scaly skin, gills, a human-like head and a fish-like tail.

The little mermaid claimed to be from the city of Atlantis and told researchers that millions of years ago, the continent of Atlantis spanned Africa and South America before sinking to the bottom of the sea......

The people who survive today live on the ocean floor and live up to 300 years. Later, the little mermaid was sent to a secret research facility in the Black Sea for scientists to study in depth.

In 1958, Dr. Rotan of the National Oceanographic Society of the United States photographed some human-like footprints on the seabed at a depth of 5 kilometers in the Atlantic Ocean.

In 1963, at the bottom of the southeast sea of Puerto Rico, during a submarine exercise of the US Navy, a strange ship was discovered, with a speed of 280 kilometers per hour, which could not be tracked, and human modern technology could not reach it.

In 1968, the American photographer Mooney found a monster near the bottom of the sea, with a monkey-like face, a neck four times longer than a human, eyes like a human but much larger, and a fast "thruster" on its legs.

In 1938, people once found a "toad man" on the beach of Juminda, Estonia, with chicken breasts, flat beaks and round heads, jumping into the Baltic Sea.

Therefore, judging from the murals, the mermaid is a creature, different from others, due to the scarcity of the number or other reasons, it is always women who are found, so there is the title of "mermaid"!

However, according to Hu Xiaodao's understanding, in ancient times, even five thousand years ago, the whole world was a matriarchal society, and women were the masters of the house, so the probability of women surfacing was much higher than that of men, so the explanation was barely reasonable.

After reading the mural, Hu Xiaodao picked up his backpack and came to the middle disc, only to find that the disc was not as short as he thought.

Its first layer is about ten meters in diameter, and it will be shortened by one meter if it does not rise in size, and it will be about four meters in diameter when it reaches the seventh layer, which can be described as huge.

However, the strange thing is that the height of the seven layers of stones is about one meter two, and the external relief of the stone blocks is completely different except for the mountain pattern above and the water pattern below.

The first layer depicts the various creatures of the ocean.

The second layer depicts a variety of trees and plants on the ground.

The third layer depicts a variety of animals, even elephants.

The fourth layer depicts people fishing or hunting.

The fifth layer depicts soldiers with spears.

The sixth layer depicts some people wearing robes.

The seventh floor depicts a man wearing a sacrificial garment with a scepter in his hand.

Unconsciously, Hu Xiaodao had come to the seventh layer with his backpack on his back, only to find that there were texture grooves similar to six-pointed stars on the top, including the other six pieces under his feet, all of which were equilateral six-pointed stars.

"It can't be a magic circle, right?" Hu Xiaodao was cranky.

The seven-layer disc here is easy to understand, from the lowest to the highest, perfectly interpreting the ancient class system.

These striped knives had only been seen in ancient books, and they were similar to summoning and sealing.

However, in Hu Xiaodao's view, these things are just tricks made up by the privileged class to consolidate their position.
