One of the glaciers that appeared in front of Lu Yuan's eyes looked very much like a shield from a distance.

The other looks very much like an ancient knife coin.

There is a very deep fissure at the junction of the two glaciers.

When Lu Yuan walked into the glacier, he soon found some human remnants in the cracks between them.

From these things, Lu Yuan inferred that outsiders had been here.

Because this area has long been deep into no man's land.

Local herders generally don't come here, and it's unlikely that tourists will come here.

It can be inferred from this that the greatest possibility is the Nazi expedition of that year.

After Lu Yuan made a judgment, he decisively entered the glacier crack.

After Lu Yuan walked into the crack, he found that because both sides of the crack were blocked by glaciers, the temperature in the crack was much higher than outside.

For the first time in so many days, Lu Yuan experienced a warm feeling.

Walking among the cracks, Lu Yuan actually found some plants.

"What a place to be!"

After observing the surroundings, Lu Yuan couldn't help but sigh.

Although this is only the junction of two glaciers, Lu Yuan found that not only the climate here is very warm, but also the soil is good.

In Lu Yuan's view, this place is actually very suitable for human survival, and if this place is renovated, it can even be reclaimed as a piece of cultivated land.

This discovery made Lu Yuan feel very strange, although the glaciers on the east and west sides blocked the wind, the temperature should not be so high.

And what made Lu Yuan even more strange was that the oxygen content here was actually higher than that of the surrounding area.

The oxygen content here is not at all lower than that in the Yunnan-Guizhou region.

You must know that this is more than 6,000 meters above sea level, and the Yunnan-Guizhou Plateau is only 2,000 meters.

"Is there really anything special about here?" Lu Yuan continued to walk forward in confusion.

The further you go inside, the more plants you see along the way.

Later, you can still see some trees, and from time to time you can see some animals.

Lu Yuan felt more and more that this place was full of mystery.

After walking about two kilometers forward, a huge cave appeared in front of Lu Yuan.

Before entering the cave, Lu Yuan felt a warm breath rushing towards him.

Not only that, but Lu Yuan also felt that the oxygen content in the air had risen sharply.

"Could this be the legendary Shambala?"

In Lu Yuan's opinion, this huge cave is too mysterious, and it can constantly provide oxygen to the outside.

Lu Yuan couldn't wait to go in and find out.

He walked quickly into the cave, and it dawned on him that it was even bigger than he had imagined.

In Lu Yuan, this cave can apply for Guinness World Records.

The highest part of the cave is at least 300 meters, and the widest part of the cave is estimated to be at least 5 kilometers.

This cave can't even be called a cave anymore, it's better to call it the mountain world.

Because a whole ecosystem has actually been formed in this cave.

All kinds of plants were growing in the cave, and Lu Yuan only took a cursory look and found hundreds of different plants.

In addition to plants, there are also many animals in the cave, and there are some animals that Lu Yuan actually found that he didn't know at all.

However, he wasn't sure if it was a new species, maybe he was just a loner and hadn't seen it before.

At this moment, Lu Yuan's mood was very happy, even if this cave was not Shambala, it was a major discovery for the world of biology and geography.

Lu Yuan suppressed his excitement, took out the shooting equipment, and took a full range of shots around.

Because he wasn't sure if there was an unknown danger here, he didn't upload the videos and photos he took to the Internet.

After finishing the shooting, Lu Yuan put away the equipment and went to the depths of the cave.

Although it is in the middle of the mountain, there are several openings at the top of the cave to bring in light, so the cave is not dark.

As Lu Yuan walked, he observed the surrounding flora and fauna, and from time to time he would stop to observe some plants that he had never seen before.

When Lu Yuan stopped again to observe a strange-looking plant, he inadvertently looked up at the top of the cave.

That's when he suddenly noticed something strange above the cave.

Out of curiosity, Lu Yuan finally climbed to the top of the cave with great effort.

That's when he realized the strange object he had found.

The object is apparently man-made, and from its appearance, Lu Yuan speculates that it should be a lighting device.

After putting this item away, Lu Yuan continued to search for the roof of the cave, and soon he found a second identical item.

Next, Lu Yuan found more and more lighting equipment on the top of the cave.

There are three models of these things in terms of size.

After careful observation, Lu Yuan concluded that this kind of thing also uses electrical energy, but their technical content is obviously much higher than that of modern lighting equipment.

From this, Lu Yuan judged that these things were definitely not left behind by the Nazi expedition.

The technology of the Second World War did not reach such a level at all, let alone the Second World War, and even today it cannot reach this level.

What's more, there were only five people on the Nazi expedition, and they didn't have such a thing as a storage dozen, so it was impossible to bring so much lighting equipment here.

After some observation, Lu Yuan found that the shape of this cave was too regular, and it really didn't look like it was naturally formed.

"Could it be that this was once a base for aliens?"

Lu Yuan suddenly thought of the saucer-shaped flying machine created by the Nazis at the end of World War II.

It's hard to believe that the Nazis were able to suddenly produce such a bizarre flying machine without any references.

At that time, the Third Reich was on the verge of collapse, and all kinds of supplies were already very insufficient.

If one were not certain enough, it would be reasonable to assume that the Nazis would not have wasted their limited resources at will.

I believe that any normal person would have concentrated all his resources to create weapons and ammunition that were urgently needed on the battlefield in that situation.

No one would foolishly waste a lot of materials on useless things in such a time of crisis.

Were the Nazis really stupid, apparently not stupid, not only not stupid but a very smart bunch of people.

Otherwise, they would not have been able to create so many advanced weapons, and they would have almost unified the entire Old Continent.

Lu Yuan deduced that the Nazi expedition had actually found the cave and found a flying saucer in the cave.

It was because they found the flying saucer that they were able to convince Hitler to support them in the production of the saucer after returning home.

It's a pity that when new weapons appeared, it was too late, and it was powerless to rely on just one or two advanced weapons......
