After Lu Yuan learned the news of Langar from Nie Ankou, he decided to go to the local area to find out. Maybe you'll be able to discover more secrets.

But now the first priority is to send the five children back to Yingzhou, Kabul is too dangerous and completely unsuitable for the children's life and growth.

Three days later, Anthony's men finally arrived in Kabul. After sending the children away, they were finally able to move freely.

Lu Yuan planned to go to Langar first, and then find a way to figure out who wanted his life.

A week later, Lu Yuan arrived in Langar, the northernmost city in Afghanistan.

Langar borders Tashkurgan in Zhuxia. Although the two places are not far apart on the map, they are actually very difficult to navigate.

Because there is a natural barrier between the two places---- the Karakoram Mountains.

Although this place in Langar is very remote, it is a rare paradise in Afghanistan.

Because it is located within the Wakhan Corridor, the entire area belongs to the Hindu Kush Mountains.

The Hindu Kush Mountains are part of the Pamirs, so the whole area is steep and extremely difficult to navigate.

But it is precisely for this reason that Garland is far away from the ravages of war.

Lu Yuan stayed in Langa for 2 days, and after confirming that no one was following him, he walked into the mountain alone according to the clues provided by Nie An.

After entering the mountains, Lu Yuan truly realized the power of the Pamir Plateau.

This place, which has been called the Green Mountains in ancient times, is even more difficult to walk than the plateau, which is known as the roof of the world.

The average altitude here is over 4,500 meters, and the main peaks are above 6,000 meters.

The Kunlun Mountains, the Karakoram Mountains, the Hindu Kush Mountains and the Tianshan Mountains converge here, resulting in interlaced mountain ranges, complex terrain, high density of river networks, deep cutting, and serious damage to the razing plane.

The two places seem so close that you can even hear each other shouting, but it often takes a whole day to get to your destination.

Not only that, but there are also huge glaciers, the largest of which is 77 kilometers long.

In a place with such a harsh natural environment, Lu Yuan really couldn't believe that there would be a highly developed civilization here.

Lu Yuan walked through the mountain ranges, and it had been almost a month since he entered the mountains.

Nothing has been found, except for the recovery of several frozen animal carcasses.

The place he was going to today was already the last mountain, and if he still didn't find it, he had to leave for a while.

Because there was another country beyond that, he didn't want to sneak across the border because of that.

As you descend from the ridge, the temperature gets warmer and the vegetation grows more lush.

At this time, he suddenly noticed that a sinkhole appeared in the direction of five o'clock in the southeast.

This sinkhole is very large, and Lu Yuan's visual inspection shows that its diameter should be more than three kilometers.

"I really didn't expect there to be such a big sinkhole here!"

Lu Yuan sped up and walked towards the sinkhole, and twenty minutes later, he reached the edge of the sinkhole.

At this time, Lu Yuan noticed that this sinkhole was not only large, but also very deep, and its depth was at least 200 meters.

Lu Yuan checked the information and found that this sinkhole was still an existence that no one had discovered.

And when you look at it from the sinkhole, you can see that there is such a green place surrounded by snow.

It's really beautiful at first sight. "It's better to be happy alone, than to be happy with everyone!"

Lu Yuan couldn't help but share the beautiful scenery in front of him with others.

So he turned on the live broadcast equipment and started the live broadcast work again.

"Lu Yuan, what good things are you going to live broadcast for us this time?"

"I just discovered a beautiful fairyland, I hope you can enjoy it!"

After Lu Yuan said this, he pointed the camera at the beautiful scenery in front of him.

"It's so beautiful, what kind of place is this?"

"It's really beautiful, if only I could live in a place like this......"

Lu Yuan broadcast live for about half an hour, and then turned off the camera.

After eating something above the sinkhole and replenishing his strength, Lu Yuan went down to the sinkhole.

He found that many of the plants in the sinkhole were something he had never seen before.

He was very curious about these plants, and would stop from time to time to observe them.

Especially some of the tall trees in the sinkhole, Lu Yuan always felt that they should actually belong to the ferns.

These trees are nothing more than enlarged ferns.

Could it be that these plants were left over from tens of millions of years ago?

With such doubts, Lu Yuan took some videos and high-definition photos of these trees that were suspected to be ferns.

He's going to get some botanists to look at it when he gets back.

Lu Yuan walked slowly through the sinkhole, and he found that the creatures here were very rich.

A wide variety of animals live in this small sinkhole.

That's when he spotted a huge tree with a diameter of at least 5 meters.

Lu Yuan walked quickly to the tree and walked around the tree several times, but he still couldn't recognize what kind of tree it was.

He took out his camera and took a few high-definition photos of the tree.

While taking pictures, he noticed that something seemed to exist on the tree.

Put away the camera, Lu Yuan was afraid to go up to the trunk, and Lu Yuan found some traces of human activity on the trunk.

These marks include stranglement marks from the rope, as well as some knife marks.

"Someone has been here before!"

Lu Yuan judged, "Who has been here, is it Nie's parents?"

Lu Yuan jumped down from the tree and searched carefully.

Sure enough, he found some traces in the vicinity.

Following these traces, Lu Yuan eventually came to the eastern edge of the sinkhole.

There is a cave here that is not counted, and after Lu Yuan looked around, he walked in.

As soon as he entered the cave, he smelled a foul smell.

Two mutilated skeletons appeared in front of him.

Lu Yuan held back the discomfort in his heart and examined it carefully.

In his travel bag next to his body, he found some identification.

"Alas"

He sighed, judging from the identity certificate, these two skeletons should be Nie Case's parents.

He then took a closer look at his surroundings and the scars on his bones.

"Wildlife must have done it!"

Lu Yuan made a judgment, but he was still not sure if there was anyone else who had come here with Nie Case's parents.

After Lu Yuan gathered the two skeletons, he continued to walk towards the cave, which was very wet, and there was even an underground river inside.

Lu Yuan walked along the underground dark river, about five kilometers or so, and his eyes suddenly lit up. A small valley appeared in front of him.

This valley is not very large, about 0.4 square kilometers.

In the middle of the valley there is a huge stone house.

Because it has been uninhabited for a long time, it has been occupied by various plants and animals.

Lu Yuan was excited about this discovery, "Maybe I can find some good things here!"

He walked quickly towards the stone house, and at that moment a strange roar suddenly came from inside the stone house.

Lu Yuan couldn't help but stop, and at this time, two monsters that were more than three meters tall, with white hair all over their bodies, and walked on their own, rushed out of the stone house.

"Snow monsters!"

Lu Yuan was shocked, he didn't expect to encounter the legendary snow monster here.

The two snow monsters took the initiative to attack as soon as they saw Lu Yuan.

These two snow monsters are very fast and powerful.

If ordinary people encounter them, they are clearly not opponents.

But Lu Yuan is not an ordinary person, Lu Yuan, who has mana and a witch body, is above the snow monster in terms of strength and speed.

In just a dozen seconds, Lu Yuan subdued the two snow monsters.

After some tuning, the two snow monsters finally realized the strength of the little man in front of them.

They finally stopped resisting and honestly followed behind Lu Yuan.

After recovering the two snow monsters, Lu Yuan entered the stone house.

The stone house has a total of six rooms and looks like a handicraft workshop.

The largest hall is occupied by two snow monsters.

The other rooms look like they're still in their place.

Lu Yuan casually walked into a room, and as soon as he entered the room, he was shocked by the scene in front of him.

In front of him appeared a large number of weapons made entirely of crystal, including spear heads, short swords, and even crystal arrowheads.

Lu Yuan collected these weapons with a small wing.

Each of these crystal-made weapons is very sophisticated. It shows superb production skills.

These weapons surprised Lu Yuan and him, because there were no huge crystal mines in this area itself.

And to make these crystal weapons, you need a lot of crystals, and these crystal mines are obtained from there.

With doubts in his heart, Lu Yuan opened the doors of the other rooms again.

In the other rooms, he found some more crystal weapons, as well as a large number of crystal raw materials.

Lu Yuan moved all these things into the Xiaoding space.

Then he took out a special detection tool from the Xiaoding space.

After some testing, the time when these crystal weapons appeared was no later than 7,000 years ago.

Lu Yuan couldn't have imagined that someone here would be able to make such a sophisticated crystal weapon 7,000 years ago.

You must know that the texture of crystal is very hard, and it is even more difficult to polish it well than to make bronze and iron.

Lu Yuan boldly began to hypothesize that it was likely that these prehistoric humans had come into contact with more advanced civilizations.

Lu Yuan's first suspicion was the influence of the Naka tribe on the local area.

In the clay tablet written records where the body poison was found, the Naka people were originally also a people of the Mu Empire.

In the later period of the Mu Empire, due to the population explosion of the Mu continent, the Naka people, like the Kara people, chose to colonize outward.

Now everyone knows that the Kara people colonized the East and established the Kara Empire in the Amazon.

The Naka went in the opposite direction, choosing to go west, landing in the east of Shenxin, and eventually establishing the Naka Empire in Shengu and Central Asia.

The Green Ridge Plateau itself is located in Central Asia, and it is also very close to the body poison.

If the ancient Green Ridge area was influenced by the Naka people, it is entirely possible that they have obtained highly developed crystal making technology.

But the discovery that followed immediately overturned his suspicions......
