After the avalanche, everything seemed to come to a standstill, even the goose feather snow in the sky had stopped, the wind on the snow-capped mountains had stopped howling, and the dark clouds that had suppressed the entire mountain range were dissipating.

The avalanche had flattened, and the ridge's rugged surface was now smooth, and the thick snow filled everything up.

Approaching a gentle slope at the top of the ridge, the flat snow suddenly appeared as a depression like quicksand, and slowly the depression grew larger and larger.

"Poof!"

A jet-black sapper shovel penetrated the snow and stretched out from the bottom of the depression with difficulty, perhaps the owner of this sapper shovel felt that it had been dug through, and instantly increased its speed, and the loose snow around it began to accelerate the speed of collapse.

Soon, a jet-black glove came out of the snow, followed by the other hand.

"Poof!"

A figure covered in ice flowers broke through the soft snow, but there was no cheer, just swooped forward again, collapsed on the snow and began to breathe in the thin air of the plateau.

This is Terry, who has been crushed by an avalanche for several hours.

There was no time to rejoice in his escape this time, Terry just rested for a while, took out a pot of water from the space and poured a few sips, looked at the sky that had begun to clear, and took heavy steps towards the top of the ridge.

Due to the delay of this avalanche, Terry, who had already lost his means of transportation, became even more urgent, after all, the situation of the Revolutionary Army was not too optimistic, if he could complete the task one day earlier, then the Revolutionary Army would have one less day to delay at the border.

Although Terry almost exhausted all his strength in the past few hours of getting out of the trap, facing the ridge that was only not far away, it felt like he was climbing the tall snowy mountains of Kharb, but Terry did not dare to have any idea of resting, gritted his teeth, and finally climbed to the top of the ridge with a wriggling speed.

The sky had cleared, and although the sunlight did not make people feel a trace of warmth on their bodies, it made the field of vision no longer so narrow, and Terry could easily see the scenery on the other side of the ridge as he climbed to the ridge.

This is another herringbone valley, but one look at the horseshoe-shaped collapse surface tells that it is a landslide canyon caused by a mudslide.

The slope of the side where Terry stood was relatively gentle, but on the opposite side was a steep cliff, and the vertical height of hundreds of meters could not even accumulate snow, and the dark blue granite seemed out of place with the surrounding white environment.

Near the base of the herringbone, a large half-buried hole appeared in the lower part of the cliff.

Although half of the cave was buried at this time, and the thick snow was thick, it was still more than 2 meters high, and the arc-shaped edge of the cave was very neat, and Terry's eyesight could vaguely see that there were many thick strips of objects neatly arranged on the arc-shaped edge.

After just a few glances, Terry no longer delved into how all this came about, but from the shape of the entire cave, Terry could see that this was the secret passage he was looking for.

Although he only rested for a while, Terry felt that his strength had recovered a lot, took out his skis and quickly put them on his feet, and tightened the bloated down jacket with a belt, Terry took a big breath of thin plateau air, and the slide bars of his hands were the snow, and his whole tall figure slid towards the bottom of the canyon like lightning.

Coming to the cave, Terry finally saw the true face of the exposed thick strips, which were thick steel bars (steel bars) that crossed like a grid, although the steel bars that had lost their cement protection were almost embroidered by the years, but the part near the cave could still show how thick these steel bars were originally.

It is a cliff formed by a collapse, but the black granite and gray cement walls can be clearly distinguished.

On the broken cement walls, in addition to the thick steel bars wrapped in gray cement, there are also some exposed I-beams, this ingenious design shows that the engineering level of the construction of this cave is very high.

This is only possible with the level of technology of prehistoric civilizations, and if it is based on the current situation, such a project is simply an incredible miracle.

However, thinking of the huge planes, trains traveling at hundreds of kilometers per hour, ships with a displacement of hundreds of thousands of tons, and even the large spacecraft that can fly out of the planet and reach the boundless space at the end of the video, Terry is relieved of such a project.

After feeling the greatness of this prehistoric tunnel project for a while, Terry put away his skis and quickly climbed over the half-buried pile of caves into the dark cave.

Pulling his flashlight out of the space, Terry slowly descended the collapsed stone to the bottom of the cave.

The ground was all silt, but it had been frozen hard, so Terry didn't have much effect on his speed when he walked on it, except for a little slippery.

The whole cave is straight and deep, except for a large number of stones and cement residues at the entrance, after entering the cave for dozens of meters, it begins to become empty.

The silt on the ground is still very thick, it is estimated that the dust that has been blown in for many years has accumulated, but there are also many ravines, which are estimated to be caused by the erosion of the mountains and rivers, and the bottom of the ravines leaks out of the hard cement floor.

Of course, Terry is not an architect or geologist, let alone an archaeologist, and what makes this prehistoric man-made structure survive hundreds of thousands of years can be so well preserved, Terry doesn't have the heart to know now.

Under the illumination of the flashlight, he hurriedly took a look at the environment of the cave, and after finding that there was no danger, he began to stride deeper into the cave.

Time passed slowly in this boring journey, this cave is indeed very long, Terry can't help but admire the power of the prehistoric civilization even more, because he has been traveling in this cave for about 2 hours, and he has not found the exit.

You must know that with the speed at which he travels, he can't say that he can say that he is comparable to a fast horse, but he is not much slower than an ordinary long-distance runner, although he stopped for a few minutes to rest in these two hours, but Terry knows that he has walked at least more than twenty kilometers.

Along the way to the cave, I really didn't find any particularly dangerous sections, although there were many places where there were collapses, but that should have happened a long time ago, and if there were no violent tremors, there should not be new collapses in those places.

However, there was a collapse point that almost completely sealed the entire huge cave, leaving only a crack about 1 meter square for people and horses to pass through, but this would not affect the movement of the revolutionary army, which had no baggage, so Terry was relieved.

"Huh, what's the sound?"

An eerie chirp came from ahead, causing Terry to be on his toes in an instant.
