After driving the snowmobile on the glacier for another hour, Tang Feng came to the crack.

When he used the star core to survey just now, Tang Feng didn't determine how big this crack was, but when he really stood in front of this crack, Tang Feng felt how wrong his idea was.

This ice cap crack is much larger than the ice cap cracks that Tang Feng encountered on the Antarctic Peninsula before, and the width of this ice cap crack is at least more than 30 meters, as for the length, Tang Feng is really difficult to judge, because with the detection radius of 57 kilometers of the star core, it is impossible to find the end of this crack.

And what made Tang Feng feel the most terrifying was that when the fierce wind blew over this crack, the wind with a speed of nearly 20 m/s could not pass through this crack, and all of them were sucked down by this crack.

Of course, this is the place where Tang Feng is located, not far from Tang Feng, the crack is not absorbing the wind inward, but constantly spewing out a white column of air, as if the wind that was attracted from here went around in a circle in the crack and was sprayed out from another position.

This situation is clearly that this ice cap crack more than 2,000 meters deep is too deep and too wide, and it actually produces turbulence, which is the so-called air turbulence. Like Russia's Peace Diamond Crater, the 533-meter-deep and 1,600-meter-diameter crater creates air turbulence that can suck helicopters flying directly above it.

Although this ice cap crack is not as large as the Peace Diamond Crater, this ice cap crack is deeper and longer, so it is not surprising that there is strong air turbulence in this particular environment.

Tang Feng subconsciously took a few steps back, who knows if this kind of air turbulence will affect the edge of the crack, in case there is a strong turbulence, maybe he will be able to suck his hundred and ten catties into it at once

Through the star core. Tang Feng could see very clearly what the bottom of this ice cap crack looked like. The bottom of this ice cap crack is about the same width as the top, about 30 meters, but the bottom of the ice cap crack is no longer a glacier, but a thin layer of ice, not even a meter thick. The cracks in the front strip were as if they had been torn apart by Hercules' axe, and the ice walls on both sides were extremely smooth. It is estimated that this is a masterpiece of intense air turbulence for I don't know how many years.

You must know that strong winds are sometimes no weaker than flowing water, and in many places on earth, those hard rocks will be modified by violent winds in a variety of strange shapes over millions of years.

I don't know how many years this ice cap crack has existed, and the strong air turbulence in the crack is no less than the winds that define the earth, so it is not a strange thing that these hard glaciers have been blown flat.

The bottom of the ice cap crack is not all in contact with the rocks on the ground, just about two or three kilometers in the middle. The bottom is in contact with the rocks, and the bottom of the crevasses everywhere else is covered with a thick glacier, and the deeper the cress becomes, the shallower the depths of the cresmets, but even if they are shallower, the depth is more than a thousand meters.

In a slightly shallower position, though. The air turbulence was also not so strong, thought about it. Tang Feng still decided to go down from those slightly shallow positions.

After getting on the snowmobile, Tang Feng walked east along the crack, and after walking about 20 kilometers, Tang Feng got out of the car again. The depth of the cracks in the ice cap here is almost a thousand meters, and most importantly, the air turbulence here is already very small. The wind blowing over the crack would hardly be attracted to the crack.

Stopped the snowmobile about ten meters away from the crack, turned off the fire, and then Tang Feng began to dig the rope out of the space.

These ropes are static ropes made of Kevlar fiber, but they are not the same Kevlar ropes that Tang used last time he fished for the island's treasures in the Caribbean. The Kevlar static rope that Tang Feng took out now is thicker, with a diameter of 11 mm.

This thick Kevlar static rope has a breaking pull force of up to 10 tons, not to mention sending Tang Feng down, even if it is a snowmobile. Moreover, the thermal properties of this Kevlar static rope are excellent, and there will be no problems with this rope in the environment of minus 196 degrees to minus 330 degrees.

It's just that the static rope made of this Kevlar material is a bit heavy, and the weight of such a rope of more than 1,000 meters is almost 100 kilograms. However, Tang Feng has a star core, so there is no need to worry about this.

Standing next to the crack in the ice cap, Tang Feng carefully lowered the rope, and put it for five minutes before putting the static rope with the lead sinker on it to the bottom of the crack. The other end of the rope was threaded from the GRIGRI descent in the normal order, and the rope was attached to the snowmobile's tow hook.

GRIGRI is a kind of downhill used in the process of downhill, of course, in addition to GRIGRI, you can also use the figure 8 ring or ATC, it mainly depends on the user's preferences and habits.

Tang Feng likes GRIGRI more, so this time he is going to use GRIGRI when he rappels down from this ice cap crack. The most important thing is that GRIGRI is a relatively safe downhill device, with the function of automatic locking, which is a crack up to thousands of meters deep, and the temperature is so low, in case Tang Feng misses, then GRIGRI can automatically lock the rope through the bite of the gear at the critical moment, so as not to let Tang Feng fall.

PUTTING THE THREE LITTLE ONES INTO THE SPACE, PUTTING ON THE HELMET AND OTHER SAFETY EQUIPMENT, FASTENING THE SEAT BELT, AND HANGING THE SAFETY LOCK ON THE GRIGRI, TANG FENG STOOD ON THE EDGE OF THE ICE CAP CRACK, TOOK A DEEP BREATH, AND THEN BEGAN TO LAND TOWARDS THE BOTTOM OF THE ICE CAP CRACK.

The wind here is not strong, and it does not affect Tang Feng's rappelling action, Tang Feng kicked the ice wall of the ice cap crack, sliding down one by one, and it took about twenty minutes for his feet to stand on the glacier at the bottom of the crack.

The rope or something, Tang Feng didn't take it back, but put it in place, who knows if he had to point to this rope when he came back.

The bottom of the crack is not cold, on the contrary, it is much warmer here than above, and Tang Feng estimates that the lowest temperature here is at minus three or four degrees.

There was no wind at the bottom, it was very quiet, and the flat and smooth ice wall stretched all the way up from the bottom.

Because of the reflection of the ice wall, the bottom of the crack is not only not dark, but very bright. Tang Feng beckoned, took out a snowmobile from the star core space, stepped on, and with a twist of the throttle, the snowmobile drove along the glacier at the bottom of the crack, thinking about the deeper crack in the south.
