Xiao Zhan was dressed in polar equipment, which was a must to enter the Arctic Ocean, from head to toe, from the inside to the outside, all of which were clothes adapted to the polar climate.

This kind of polar equipment is hard to find, and it is definitely not available on the market.

It has very high requirements for warmth, softness, prevention, transparency, excellence and glamorousness, and from the perspective of material, it is almost equivalent to aerospace clothing, whether it is a fleece jacket or spikes, all of which are required to reach the aerospace level.

Only by reaching the aerospace level can the survival of man in the polar environment be guaranteed.

In the North Pole, the minimum temperature can reach minus 70 degrees, although it is 20 degrees worse than minus 90 degrees in the South Pole, but these 20 degrees are really not much different for a person.

Three pairs of cashmere socks, with seal leather boots on the outside, even if the protection is so tight, the warmth is extreme, but it can't stop the cold from the surface.

After the breakup, Xiao Zhan embarked on the journey of extreme survival alone, he knew very well that extreme survival was only secondary, the main thing was to find this unknown corpse, and then find the hidden secret from the corpse.

As for whether the corpse had anything to do with genetic weapons, he didn't know, but as far as it mattered, it should be related to this matter.

The tundra is so vast that I don't know how long we have to travel.

Xiao Zhan chewed on the energy bar while observing the distance with a telescope.

Compared to the pristine rainforest, the danger of the Arctic Circle is not in the ground beneath your feet, because there are no invisible swamps here, and the tundra is beneath the permafrost, which is extremely strong.

The most dangerous is the harsh climate, as well as the lack of food.

Almost all of the people who die in this polar region freeze to death.

High-calorie food is a must, tents and sleeping bags are also necessary, and finding the corpse must be established under the condition of survival success to the limit, Xiao Zhan is very cautious to distribute his food reasonably.

You know, it will take many days to walk into the Arctic Ocean from here, and there is only a limit to what one person can bring.

"Whew...... Whew......"

Standing on a high place, Xiao Zhan exhaled white gas, and when he saw the area in front of him, he immediately closed his mouth tightly, held his breath, his pupils contracted, and the whole person showed an extremely cautious expression.

It was a low tundra grass, full of corpses, and there was an eerie aura everywhere, like a hell that existed in the world.

A hundred?

No, there are more than a hundred corpses here, there are countless of them.

There were five or six football fields-sized areas, littered with corpses, almost all of them animals, but there were also scattered corpses of people.

Xiao Zhan slowly squatted down, took out a telescope to observe the corpses here, and found that each corpse was shriveled, and the time was long and short, as if the flesh and blood had been sucked dry by something.

Because of the cold, the bodies did not appear to be decomposing, because the temperature here was very low, even in the hottest part of the summer, during the day, only a few degrees Celsius.

The corpse had not had time to decompose, and in the evening, it was frozen and refrigerated.

At this moment, Xiao Zhan's mind was thinking of the valley of death.

Death Valley in the Kronotki Mountains of Kamchatka, Russia; Desert Death Valley in California and Nevada; Death Valley near Naples and Wavelno, Italy; Valley Cave, Java, Indonesia; There is also the Nalengrad Gorge near the Kunlun Mountains in China, known as the "Gate of Hell" in the Kunlun Mountains, and the valley is full of wolf fur, bear bones, hunters' steel guns and barren hills and lonely graves.

These Death Valleys exist in the world as horrors, and why they became Death Valleys cannot be explained by science until now, and it has always been a mystery.

This is not something that modern humans can explore, and it is this unknown that is the most frightening.

The scene in front of him made Xiao Zhan feel cold in his hands and feet, and he could clearly feel an eerie and terrifying aura of death.

And this breath made him very uncomfortable, and he immediately felt the urge to retreat.

But this is the only way to go, and there is no way to detour.

An unknown tide of fear swept in, and Xiao Zhan stayed where he was for a while, trying to observe the possible danger and try to discern the cause of the corpse's death.

But he observed for a long time, but he didn't find the problem.

Whether it is an animal corpse or a human corpse, there are no wounds on the surface, but the appearance of flesh and blood has been sucked dry.

In addition, there were no traces of lightning strikes in the area ahead, which was different from the Death Valley of Kunlun Mountain.

Seeing widespread death without knowing the cause is a source of fear for anyone.

Why do humans have totems? Why is there a religion? Essentially, it's the fear of the heart, and then to worship, the desire to gain faith through surrender.

What exactly causes it?

I don't know, but the smell of death is getting stronger and stronger, and the fear of death is becoming more and more terrifying for Xiao Zhan.

"Hoo ......"

Xiao Zhan gently exhaled a breath of turbidity, and slowly stepped out with his left foot, entering this dead dwarf tundra.

He walked very carefully, lest he touch something he shouldn't.

One, two, three, four......

The two feet were so light that they didn't even make the sound of grass moving, and slowly, slowly, and forcefully endured the tingling sensation of their scalps, and came to the corpse of an animal.

Slowly pulling out the saber and slowly squatting down, Xiao Zhan gently poked the corpse with the saber.

There was no particular reaction, as the corpse was stiff due to the cold, but its stiffness was consistent with the characteristics of the corpse.

He then gently cut the corpse's fur with his saber.

"Whew-"

There was a slight tear of leather, and the fur, which had become brittle, was sliced open, revealing the dry muscles within.

Through the identification of the color of the muscles, Xiao Zhan was once again sure that these corpses had been sucked dry of blood and died.

But what about wounds?

No harm!

He thought of vampires, and even examined the neck of the corpse to see if there were any tooth marks from the fangs.

And the result is obvious, there is no wound at all, there is no wound at all on the whole body, it is so completely sucked up and died.

At this moment, the goosebumps on Xiao Zhan's body exploded, his scalp was numb as if there were countless ants gnawing inside, his hands began to weaken, and his heart was beating wildly.

What the hell is going on with these corpses all over the mountain, and how did they die?

Supernatural powers? A mystery that science can't explain?

Xiao Zhan swallowed a mouthful of saliva, feeling uneasy in his heart, resisting the urge to escape.

He is not afraid on the battlefield, because at least he knows how to die, but here he is really scared, maybe he doesn't know how to die.

I thought that there would not be much danger here, it was nothing more than fighting the climate, but now it seems that this place is not simple.

At this moment, Xiao Zhan's eyelids throbbed violently, and an extremely dangerous aura struck!
