After passing through the swamp, you will come to a high mountain.

Chen Rui took out the map from his backpack and pointed to the location of the mountain on the map with his finger. Then, with his finger twiping across the map, he took a spot in the long stretch of mountains and muttered to himself, "The Treasure Valley should be here." ”

Chen Rui put away the map, put it in his backpack, and continued on his way.

A few days later, a man and a tiger appeared in a valley.

The valley was deep, and people were standing at the entrance of the valley shouting, and the sound was heard far and wide in the valley.

"This is the valley."

The valley is large, densely wooded, overgrown with branches and vines.

The ground was covered with a thick layer of dead branches and leaves, dark and damp, and the air emitted a ** smell.

In the rotting leaves, lurking a lot of poisonous insects, poisonous snakes.

It is difficult for people to walk through it, let alone a large animal.

In order to avoid accidents, Chen Rui put the black spots into the space of the pregnant sea pearl.

Chen Rui searched in the valley for most of the day, but did not find the ancient city full of gold and gems written in the diary of the Spanish explorer Fred.

Chen Rui walked alone in the valley.

The valley was full of trees and vines, branches and vines that blocked the sun, and the ground was very dark and damp.

The surroundings were very quiet, so quiet that Chen Rui felt a little depressed and simmering.

Chen Rui walked cautiously on the edge of the valley.

A piece of soft soil under Chen Rui's feet suddenly slid and collapsed because it couldn't bear Chen Rui's weight.

Chen Rui's body fell uncontrollably down the valley with the collapse of the soil.

Chen Rui's eyes were quick, and he grabbed a sturdy vine hanging down in mid-air, stabilized his body, and the vine hung Chen Rui in mid-air.

Chen Rui looked down, and the scene in front of him suddenly shocked Chen Rui.

At the bottom of the valley is an ancient city, the one that Fred wrote about in his expedition diary, which is full of gold and gems.

Chen Rui looked up, his eyes were all green, green leaves and tangled vines blocked Chen Rui's vision, and only a few rays of sunlight leaked out of the gaps left by the dense leaves and vines, shining into the valley.

The bottom of the valley is completely obscured by trees and vines, and the ancient city below is not visible from above.

That's right, too.

If the ancient city had not been covered by trees and vines, the scale of the ancient city below would have been revealed at a glance on the map of the valley and song.

It has already been discovered, so why wait for Chen Rui to come and hunt for treasure.

Chen Rui's whole person was hanging on the vines, above the ancient city, and the scene of the ancient city below was unobstructed.

The ancient city is very large, but it has become very vicissitudes of life after years and wind and rain, with mottled walls, moss-covered steps, and big trees rooting in the cracks of the walls."

From the tall and ornate palaces and temples of the ancient city, the walls made of polished and smoothed bluestone, and the huge and elaborate sculptures of the people standing in the center of the city, as well as the tall pyramid buildings, etc.

It can be seen that a very advanced ancient civilization lived here a long time ago, and they built this city.

Climb down the vines, climb to the bottom of the valley, and enter the ancient city.

As soon as he walked into the ancient city, the scene Chen Rui saw confirmed Chen Rui's speculation.

In the ancient city, Chen Rui found some pottery, the surface of the pottery is very smooth, the shape is beautiful, elegant decoration, beautiful geometric patterns and brilliant colors.

It shows that the Akha people have remarkable polishing techniques, exquisite zuò making techniques and a rich variety of decorative styles in pottery making.

The Aka people are the name that Chen Rui gave to the people who lived here a long time ago.

Because the mountain range where this valley is located is called artka in the local indigenous population, translated as Aka in Chinese, and the people who live in the artka mountain range are also called Aka.

This is the same reason that the Yuanmou people were named Yuanmou people because they were found in Yun, Nanyuan, and Mou counties.

The Acre people also excelled in metal smelting and processing, as can be seen from the bronze knives, swords, spear tips, axes and other weapons found by Chen Rui in the city of Acre, as well as production tools such as sickles and axes.

The city inhabited by the Akha people was called Acre City.

The Akha people also have a well-developed handicraft industry, and Chen Rui found various processing workshop houses and processing tools in the city of Acre, as well as various handicrafts such as gold, silver, copper, precious stones, leather, textiles, feathers, pottery, etc.

In addition to this, the Akha people also have a fairly well-developed ruling class system and religious system.

This can be inferred from the neat streets and squares in the ancient city, the temple, the royal palace, the administrative office, the noble residence, the playground, the school and other buildings in the city, and the large market in the north of the city.

Acre also has a 10-kilometre-long waterproof causeway and two stone troughs that divert fresh water from the land.

This is the fourth largest ancient civilization that is not inferior to the Mayan civilization, the Aztec civilization, and the Inca civilization, and the three ancient civilizations of the Americas, the Acre civilization.

Chen Rui walked to the center of the city, where there is a pyramid, comparable to the Egyptian pyramids and the Mayan pyramids.

The pyramid of Acre is different from the Egyptian pyramids, but bears some similarities to the Mayan pyramids.

The pyramid of Acre is flat-topped in appearance, the tower body is square, the bottom is large and the top is small, layer upon layer, and a square stone tablet is erected on the platform at the top of the tower.

The pyramid of Acre is built from blocks of polished and leveled boulders.

To Chen Rui's surprise, the junction between the boulder and the boulder is not plastered, but it is still extremely tight, and the blade is difficult to insert.

This shows the great architectural skills of the Akha people.

Chen Rui climbed to the top of the Acre Pyramid and found that the stone tablet was engraved with various patterns and words.

Explain that the ancient civilization of Acre developed to the point of possession of writing.

These patterns caught Chen Rui's attention.

A dozen concentric circles of size and size resemble a target, and below is a constellation-like pattern composed of dots and lines.

Chen Rui studied this pattern for a long time, and finally confirmed that the constellation-like pattern composed of dots and lines was the constellation diagram.

Represented is the sign of Virgo.

The rings represent the solar system, and one of the rings represents the Earth.

This is a chart of the solar system drawn by the Akha people.

The pattern of the second piece is like two calculation problems.

One horizontal and one vertical to represent the number.

Chen Rui studied for a long time, and suddenly thought of computer binary numbers.

One horizontal represents 1, and one vertical represents 0.

Then, Chen Rui put a horizontal representative of 1 and a vertical representative of 0 into this calculation problem, and the result is 365.22.

365 days a year, as modern people know, this is the time it takes for the earth to make one revolution around the sun.

But the Akha people not only came up with this number a long time ago, but also accurate to 365.2424, and the modern astronomical observation is 365.2422 a year, which is 0.0002 different from the figure obtained by the Akha people, which is a very incredible achievement.
