Tianzhu's mountain combat unit is the army with the most rich combat experience in high-altitude and alpine areas in the world.

Since 1984, Ah San has successfully built at least 150 bases here.

But seriously, this place is more meaningful than practical.

THE TEMPERATURE IS MINUS 50 DEGREES Celsius, and it is often accompanied by snowstorms and hail with speeds of up to 100 KM/H.

If it weren't for the oasis, it would obviously be impossible for Huaxia to send people to find out.

Maybe it was because of the weather, so Chen Xi and his party didn't encounter any Tianzhu sentinels along the road.

And when the all-terrain vehicle climbed over a kind of low mountain, everyone suddenly felt that their vision suddenly widened.

It is a huge plain with a gentle terrain.

The towering 10,000-year-old icebergs around it are like a barrier, blocking the wind and snow from the other side of the mountain.

If you take an airplane and look down from the sky, you will find that the topography of this place is like a gourd, connected by two oval-shaped plains, one large and one small, surrounded by mountains and mountains.

The waist part of the gourd is the so-called Siarra Pass.

The convoy crossed the low hill to the mouth of the gourd, and then suddenly stopped not far from the mouth of the gourd.

Because, everyone was shocked by the scene in front of them.

If you haven't seen a glacier, you may not be able to imagine what it was like.

The earth is white, the mountains are white, and the heavens are white.

As far as the eye can see, the white expanse is extremely full of ice and snow for 10,000 years.

However, in such a pure world of ice and snow, now a large oasis has appeared out of thin air.

The first is unscientific.

Again, it's unscientific.

In the end, it's still unscientific......

Although the weather is much better than in the morning, there is still light snow in the sky, and the whole sky is covered with dark clouds.

However, the inside of the gourd mouth was lush with vegetation and green grass, and the dark clouds and wind and snow seemed to be blocked out by the towering mountains, so that the bright sun sprinkled from the sky wantonly, illuminating the entire valley.

The driver was a little unsure of the situation, so he parked the car outside the valley for the sake of safety.

After seeing the scene in front of them, the four professors in the car immediately stepped out of the car and carefully observed the surrounding situation.

It was still snowing outside the valley, but the sun was shining inside the valley.

From a scientific point of view, there is a convincing explanation for this situation.

But what's going on with the plants inside?

Not to mention that it's winter, and this is still a plateau with an altitude of more than 6,000 meters, and the climate is comparable to that of Antarctica.

Even if there are plants in such places, they are lower plants such as mosses or ferns.

The seemingly inconspicuous grass on the side of the road is actually a higher plant, so it is absolutely impossible to appear in such an extremely cold area.

Professor He shuddered, hugged his cotton clothes tighter, and then he squatted next to him and dug up the snow.

He wanted to see the temperature of the soil.

But after digging at least half a meter deep and not seeing the soil, Professor He wisely gave up the plan.

This place is full of pine snow, and even if he digs it again, it is estimated that he will only be able to dig out a glacial belt that will not melt for 10,000 years.

While several professors were studying the environmental differences inside and outside the valley, He Tiangang quietly entered the gourd mouth with the people of the Wulian after Chen Xi's consent.

There were no soldiers along the road, so He Tiangang estimated that Ah San was hiding in this oasis, so he wanted to touch it in to see the situation.

However, when He Tiangang sneaked to the mouth of the gourd, he was a little surprised to find that there were no soldiers of Ah San in the valley.

Not even any living creatures.

There seems to be an invisible dividing line at the mouth of the valley, and the moment He Tiangang crossed the dividing line, the surrounding temperature rose sharply, as if he suddenly came to Sanya from the northeast, and even more exaggerated than that, and the temperature difference soared directly to more than sixty or seventy degrees.

The people of the Wulian immediately dispersed and went to the depths of the oasis to inquire about the situation.

At this time, Chen Xi also slowly crossed the dividing line.

But the moment he crossed the dividing line, he couldn't help but take a deep breath.

The aura of heaven and earth here is too strong......

It's comparable to Tianxuan!

Is this the vision of Reiki's revival?

Chen Xi stood at the mouth of the gourd, looking up at the blue sky above the valley slightly.

This place turned out to be a natural spirit gathering array.

Every surrounding mountain, and even every boulder, occupies a key position in the formation.

Is all this man-made, or is it providential?

Chen Xi frowned slightly, stood at the mouth of the gourd and felt it for a while, then he waved his sleeves and took away his figure, and then suddenly flew over the valley.

He looked down on the oasis from the sky, and everything in the oasis was clear to him.

Except for their group, there really wasn't even a single person in the huge oasis.

Since there are cultivators who prevent them from entering the mountain, it means that Tianzhu knows about the existence of this place and has sent people to guard it strictly.

So......

What about Ah San's people?

Probably because the oasis had just appeared, the trees in the valley were not luxuriant, except for the green meadows, which were only faintly scattered with seedlings of trees and shrubs.

When you first see this grassy valley, you can still feel amazing.

But after looking at it for a long time, this valley faintly gives people a very strange feeling.

The sun is shining and the vegetation is luxuriant, just like the park in the afternoon, but it makes people feel that it is very lonely and at the same time......

Chen Xi frowned and pondered.

It turned out that it was because there were no sounds of animals or insects in the valley, and there was no sound of wind.

The whole valley was silent and terrible.

Chen Xi flew in the sky, quietly observing the actions of everyone below.

He Tiangang led the team to carefully inspect the oasis, while several professors were busy moving various instruments out of the all-terrain vehicle.

Everything seems normal.

Aside from discovering that it was a natural Spirit Gathering Array, he didn't find anything abnormal.

But that's what makes it seem a little abnormal.

I don't know why, Chen Xi always has a feeling in his heart that the mountain rain is about to come and the wind is full of buildings.

But he couldn't say what was wrong.

This feeling......

Chen Xi frowned, pondering for a while before suddenly realizing that this feeling had already appeared once before!

And the first time this feeling appeared, it was also when he found that the earth's aura began to recover!

That's how humans react to the unknown, and that's why he instinctively feels repulsed.

He still knows too little about the Earth......
