The disappearance of the mercenary group in the busy rainforest did not cause any waves.

No one knew what had happened to them, and no one cared if they were dead or alive.

It was as if they had never existed, and they were gone forever in this world.

At the same time, Lu Yuan is also gradually approaching his destination, the Kara Empire.

Legend has it that the people of Mu Continent, who sank in the Pacific Ocean, had a highly developed civilization. And established a powerful Mu Empire, which was very good at navigation and often organized colonial groups to develop overseas.

The first group, made up of the Kara people, sailed eastward, arrived from Central America to South America, and settled down there, creating the "Kara Empire".

In addition, a group of Muguo people called the Naka tribe sailed westward, landed in South Asia and Burma, and opened up the famous "Naka Empire" in the direction of poison.

The Naka people have a high IQ and a level of science and technology that surpasses that of Mu, and the flying ships they invented often fly back to Mu, bringing with them all kinds of curiosities, gold, silver and precious stones.

At that time, the Andes Mountains had not yet been formed, and the Amazon basin was just a huge bay. The Kara built five cities there, one of which was the Golden City known as Manoa.

About 12,000 years ago, the continent was suddenly wiped out, the entire continent was swallowed up by the Pacific Ocean, and the colonial countries also declined due to the loss of the mother country.

The Kara Empire was hit by the sinking of the continent, the earth was uplifted, the Amazon River dried up, the Andes Mountains were formed, the cities became jungles, and the people returned to primitive life.

Although the Naka Empire had advanced technology and maintained a short-term prosperity, it soon experienced civil strife and self-destruction.

Later, the stories of air wars and super weapons in the myth of poison probably refer to this civil war.

The destination of Lu Yuan's exploration this time is the legendary capital of the Kara Empire, Manoa.

Lu Yuan passed through a swamp and came to the foot of a high mountain, and looked at the satellite positioning, he was now close to the Andes.

Comparing the map, the former capital of the Kara Empire, Maloya, should be within 50 kilometers of the vicinity.

Lu Yuan put away the map, ate a little, and continued to move forward.

Before the sun set, he found a huge cave, this cave looked very large, out of curiosity, Lu Yuan walked into the cave.

Lu Yuan has a large number of this cave, the inside of the cave is larger than the cave entrance, and the widest part of the cave is about 30 meters. The cave is relatively dry, and if you clean it up, it is actually quite suitable for human habitation.

I happened to be tired, so Lu Yuan took out some daily necessities and prepared to stay in this cave for another night.

After eating something and drinking a cup of tea, Lu Yuan lay down comfortably.

Suddenly, he jumped up from the ground.

He noticed something on the opposite rock face.

Lu Yuan hurriedly walked over, and there were actually petroglyphs on the rock wall.

The petroglyphs look very old, but they are still clearly visible.

Lu Yuan took a closer look at the petroglyphs, and the first half of the petroglyphs depicted daily life.

The petroglyphs depict the patterns of people trading and living in the city, and what surprised Lu Yuan the most was that the patterns of flying machines actually appeared on them.

Realizing the importance of this pattern, Lu Yuan quickly photographed all these petroglyphs.

After doing this, Lu Yuan continued to look back, and found that the next thing was mainly about war, and at this time there were giant figures on the pattern, these ancients, wearing armor and receiving weapons, regarded as the attacking side.

At this time, Lu Yuan was suddenly stunned, he suddenly found two gods on the rock paintings, and the meaning of these two gods was actually "Great Witch"!

"Could it be that the war depicted on the petroglyphs has a great witch involved!"

Lu Yuan felt more and more shocked, and then the petroglyphs also described people abandoning the city and hiding underground!

Lu Yuan looked at the petroglyph and was silent for a long time, and he began to speculate about the meaning of the petroglyph.

Lu Yuan speculates that many years ago, a group of people created a very prosperous city, where people lived in abundance and technology was also very advanced.

But one day the war broke out, and these cities were not enough to withstand the attack of their opponents, and in order to survive, the people were forced to hide underground.

The original city was obviously abandoned, and Lu Yuan guessed that the city on the petroglyphs was probably the Manoa he was looking for.

The petroglyphs show people hiding underground, which may be related to the traces of dungeons found around the world.

"Maybe there's a dungeon somewhere in this Amazon rainforest!"

However, what puzzled Lu Yuan the most was what happened to the "big witches" that appeared on the rock paintings, whether these big witches represented invaders or allies of the rock art authors.

However, one thing he can confirm is that the Great Witch, or the legendary Yu Xia, must have participated in this war.

Lu Yuan stayed in this cave for a week, and did not leave this place until all the petroglyph materials in this cave were preserved.

......

On this day, Lu Yuan came to a valley, and Lu Yuan felt that this valley was a little weird, and he felt that this valley did not seem to be naturally formed.

"Could this be the legendary Maroya?"

Lu Yuan suppressed the excitement in his heart and walked into the valley alone.

The valley is very large and very densely wooded, full of large trees that require several people to hug.

There are also vines growing between the trees. These vines are very strong and thick, some vines are actually as thick as thighs, they are very strong, and some of them look relatively old, even Lu Yuan has a hard time tearing them off.

"If it's ancient, these vines are good materials for making rattan cards, and I'm afraid the rattan cards made by them can really block bullets!"

Thinking of this, Lu Yuan simply collected some vines that were older and more resilient.

"Maybe it'll be used again in the future!"

After collecting some vines, Lu Yuan continued to walk.

Because the trees are so lush, there is some gloom in the valley.

Due to the inaccessibility of people, the ground is also full of thick dead branches and leaves, and under these dead branches and leaves, countless poisonous insects live.

If it weren't for his extraordinary physique, Lu Yuan felt that he would have died under these poisonous insects a long time ago.

This also made Lu Yuan feel sure that even if he really discovered Manoya, the capital of the Kara Empire, this time, he couldn't announce it, at least not for the time being, because this rainforest was too dangerous, and ordinary people rushed in rashly, and it was simply "ten deaths and no life"!

Lu Yuan sat alone in the valley, and the surroundings were very quiet, which made him feel very bad because it was too depressing.

After searching in the valley for most of the day but finding nothing, Lu Yuan couldn't help but feel a little disappointed.

Stopping again at the edge of the valley to rest for a moment, and recuperating his strength, he continued on his way.

Then he found that there was another area to the west of this valley, and he went west first.

Lifting the leaf that blocked his vision, Lu Yuan was stunned by the scene in front of him.

In his eyes appeared a huge pyramid, which was not exactly the same as the pyramids of Egypt.

The tops of the Egyptian pyramids are pointed, and the area is small. But the top of the pyramid is flat, and there is a building on top that looks like a temple.

But like the Egyptian pyramids, they are all so majestic.

Although the pyramid has been surrounded by a large number of vines, it is still possible to see its former glory.

In addition to this pyramid, there are a lot of buildings around it, which look a bit like they were made of stone, but with a bit of a difference.

It's clear that this is an abandoned city.

In order to see the whole picture of the city clearly, Lu Yuan climbed a mountain next to him as fast as he could.

Come to the top of the hill and see the whole city in full view.

The ancient city is very large, but after years and wind and rain, it has become very vicissitudes, the collapsed walls, the big trees will root in the cracks of the walls, and all kinds of vines have climbed all around the building......"

Lu Yuan took out the map and opened the positioning system for careful comparison.

He was thrilled to find that this ancient city was indeed Manoya, the capital of the "Kara Empire" he was looking for. That is, the legendary city of gold.

With excitement, Lu Yuan walked into the ancient city of Manoya.

Between the woods and vines, Lu Yuan discerned everything in the city one by one.

The city has gorgeous palaces, tall temples, huge statues, and perfect water conservancy facilities.

Any facility can show the strength, civilization, development and wealth of the original "Kara Empire".

Such a civilized and rich empire actually disappeared from the earth like this, which couldn't help but make Lu Yuan think about it with great horror.

Judging by the architecture of his city, the "Kara Empire" was not much worse than the current civilization.

It will be destroyed suddenly and inexplicably, so will modern civilization have the same result!

Lu Yuan continued to search carefully in the ancient city.

Soon after, he found some pottery and suspected porcelain, which were mainly household utensils judging from the pottery found.

They have a very smooth surface, beautiful shapes, elegant decorations, beautiful geometric patterns and brilliant colors.

It is clear that the Kara Empire had a striking level of polishing techniques, exquisite craftsmanship and a wide variety of decorative styles in the manufacture of pottery.

The suspected porcelain found was mainly used as ornaments, and although they were not as good as the porcelain at the peak of Zhuxia, they were still much better than those produced in other countries.

Putting all these pottery and porcelain into the Xiaoding space, Lu Yuan continued to move forward.

Soon he found a number of metal products, including knives, swords, daggers and other weapons, as well as sickles, axes and other production tools.

In particular, the swords in it are still as clean as new after so many years.

Put a grip on them and it will work fine, and it will be extremely sharp. Its metal manufacturing process surpasses even modern civilized society.
