The women of the tribe wore colorful foliage skirts, dressed up "flowery" and danced.

The men of the tribe were covered with mud and char ash on their faces and bodies, with leaves on their heads and leaves on their hands, spears sharpened from branches in their hands, and they were shouting slogans in their mouths and stomping their feet to beat their beats in a rhythmic way.

It was a very solemn ceremony.

After the ceremony, the natives offered gems and belongings as offerings to the gods, and these treasures were piled up at Chen Rui's feet like a small mountain.

Among them, a huge gem offered by the chief attracted Chen Rui's attention.

This is a huge diamond, the size of a small bowl for a human meal, pure and transparent, without any flaws, it is the best grade of diamond, the value is invaluable, the world is unparalleled.

This is probably the largest diamond in the world.

Chen Rui remembers that before this, the world's largest diamond was discovered in 1905 in the Premire diamond mine in South Africa, and the 'Cullinan' diamond, known as the 'Star of Africa', was the size of an adult's fist and weighed 3,106 carats, and was named after the name of the mine's general manager, 'Cullinan'.

The world's largest diamond was bought by the British government for $750,000 and shipped to England in 1907 as a gift to King Edward VII as a 66th birthday.

Later, the 'Cullinan' diamond was divided, cut and polished into the four largest diamonds.

'Cullinan I' was later set on the King's scepter, 'Cullinan II' was later set on the King's crown, 'Cullinan III' was set on the spire of the Queen's Crown, and 'Cullinan IV' was set on the side of the Queen's Crown.

The giant diamond at his feet is a larger and more valuable diamond than 'Cullinan'.

I guess it's the 'Star of the Americas'.

Chen Rui waved his hand in front of everyone and received these treasures into the space of the pregnant sea pearl.

At night, the natives arranged for Chen Rui to live in a cave, which seemed to be one of the most important places for the aborigines, and no one could enter the cave except for a few people.

The natives sent to the 'gods' women who were chosen by the tribe to be called the most beautiful and richly decorated. It is hoped that the 'god' will leave an heir, male or female, who will have the noblest lineage of the 'god', and that he and his descendants will be the most orthodox rulers of the tribe.

Chen Rui looked at the 'beautiful woman' sent by the natives, fat and fat, walking up, the fat on her body trembled, her skin was dark, her arms were thick, she was wearing a grass skirt, and her head was full of feathers and a headdress decorated with flowers.

The aesthetic perception of the indigenous people is just different.

Chen Rui sent the 'beautiful woman'.

Entered the space and counted the treasures.

The 'Star of the Americas', which replaced the 'Star of Africa, Cullinan' as the world's largest diamond, was held in the palm of Chen Rui's hand, shining with dazzling light, and its value was invaluable.

With the exception of the 'Star of the Americas', the possessions were mostly raw gemstones, pearls, and a lot of gold and some gold products.

In addition, Chen Rui is very puzzling that this indigenous tribe lives by hunting and gathering, and lives a very primitive and backward life, and has not formed a civilization like the ancient Incas, Mayans, and Aztecs.

They did not have the relatively advanced metallurgical process of extracting gold from gold ore and gold ore sands, let alone possessing a very sophisticated and sophisticated gold casting process like the Incas, and were able to cast exquisite gold products.

Why this indigenous tribe has so much gold and so many exquisite gold products. Or, the indigenous tribe had mastered relatively advanced metallurgical techniques and very sophisticated casting techniques.

Sitting in the cave, Chen Rui had time to observe the cave.

This is a relatively large natural cave, with an area of about 100 square meters.

Chen Rui raised his head and looked up, and found traces of smoke and fire on the top of the cave, several large soil pits on the ground, which had been burned, and there were ashes in the soil pits, and there were a pile of bones of various animals next to the soil pits, which were very scattered.

It can be pushed that the indigenous people of a long time ago lived in this cave and lived a cave life.

Chen Rui's gaze swept over the rock wall of the cave, and his gaze stayed on the section of the rock wall on the right side of the cave, where he made some discoveries.

In order to see clearly, Chen Rui walked over and took a closer look.

Sure it's petroglyphs.

A very ancient stone carving culture, the ancients carved and painted on the rock wall, stone cliff face and independent rock to depict human life, as well as their imagination and aspirations, involving the economy, society and life of primitive humans, constituting the earliest documents of primitive humans before the invention of writing.

The smooth and flat rock wall is covered with petroglyphs, which are very abstract, using lines and smudges to depict a thing or a thing.

For example, Chen Rui can see that the petroglyph depicts the deer's big horns, limbs, body, and tail with thick lines and smudges, but as for the eyes, mouth, ears, nose, hair, and other subtle things, it can only be vaguely identified from the unique features, shape, and appearance drawn on the mural.

The colors of the petroglyphs are very distinct, rich and diverse, including white, black, red, green, blue and yellow, etc., all of which are made of natural pigment particles + animal oil. For example, natural lime + animal fat = white pigment, charcoal + animal fat = black pigment, iron-rich soil + animal fat = red pigment, etc.

Many petroglyphs have been blurred, and the natural pigment particles have faded over the years, but some animals can be vaguely identified from the remaining lines on the petroglyphs, items closely related to primitive life, hunting, gathering, etc., as well as primitive hunting, gathering, sacrificial activities, and very important things happening.

Chen Rui starts with the first petroglyph on the far left.

From a few simple lines, it can be seen that the painting is a fish, which can show that people at that time lived by fishing, fish was a very important source of food, and secondly, it can also be said that there is a river nearby.

The second petroglyph depicts the scene of people hunting at that time, and the painting shows several people holding a very similar weapon hunting a very similar deer

In the sixth petroglyph, in the upper left sky, a red circle depicts the sun, and the red circle is surrounded by dense and very thin, short red lines representing the sun, and under the sun, an oval, slightly flattened disk appears in the air.

Chen Rui continued to look down, and then in the next petroglyphs, the oval and slightly flattened disc in the sixth petroglyph appeared one after another.

This is probably the earliest record of UFO alien flies.

Suddenly, one of the petroglyphs caught Chen Rui's attention.

A huge ball of fire, falling from the sky.
