Gao Chao didn't want to ask Jiang Ji's question, because no matter what he said, it was a sad thing.

So there was nothing to say that night, and everyone went back to rest in silence, and early the next morning, when it was just dawn, the old man got up.

He was alone on the side of the camp, chose a good position, buried the remains of Political Commissar Zhao Gang and Li Hong, and erected them in front of the grave with two 81 bars as tombstones.

Da Lao Hei stood alone in front of the grave, and he didn't leave for a long time, what was he thinking? Did he recall his comrades-in-arms? Did your comrades leave like this? No one knows that only soldiers can experience such feelings.

When the sun was fully above the horizon, everyone seemed to have just come out of the depression of last night, so everyone sat together again and began to discuss the plan of action for the future.

According to Zhao Gang's diary, now they have got some important information, first of all, the ancient city of Yinshan does exist, and it is on the north side of the Gawa Gapu Snow Mountain, and there is a ready-made tunnel that can pass through the Gawa Gapu Snow Mountain, and that tunnel is called Tunnel No. 1, but the specific location of the No. 1 tunnel is not very clear now, only know that it should be above the snow line, and this still needs everyone to cross the snow line to find it.

Then there is a No. 2 tunnel in the ancient city of Yinshan, which is exactly what Xia Qiu was looking for, although I don't know where the No. 2 tunnel leads, but it is certain that the secret of the ancient city of Yinshan should be at the end of that tunnel.

However, Tunnel 2 must be very dangerous, and it has been mentioned in this diary that those soldiers back then, including Company Commander Zhang Bin, were probably in Tunnel 2 and encountered something unexpected that would cause such a terrifying incident to happen.

Through the description in the diary, everyone speculated that what happened in tunnel No. 2 that night should have something to do with black blood fever, those so-called "crazy people" are very similar to people with black blood fever, they may all become "weak men", bite people when they see them, like zombies, but what is in tunnel No. 2 will make so many well-trained soldiers become weak men and have black blood, which is simply unimaginable.

And in the end, it is the 101 Institute that everyone can't figure out, that is, the 101 Institute of Geology, what is this unit for? Is it really as simple as its name? Just a geological research institute? Or does it mean something else?

As for why Xia Qiu was able to survive in the end, this point is even more incredible, the fat man didn't care about it, and asked Xia Qing in front of everyone, but Xia Qing only said three words: I don't know.

She had made up her mind that she didn't want to share that information with anyone, it was her freedom and her right, but even if she was so willful, no one could blame her, after all, if she hadn't led everyone to this base, they might not even have this information now.

In the end, everyone reconfirmed the action plan, and now what they have to do is to find the No. 1 tunnel above the snow line, and they only have such a choice, because if they want to successfully find the ancient city of Yinshan, they must go over the Gawa Gapu Snow Mountain, but their time is running out, they can only enter the ancient city in the shortest time through the No. 1 tunnel, otherwise, they will either retreat and wait for death, or die on the snow mountain, they can only succeed, not fail, failure means destruction.

After all the people were united, they repacked and set out on the journey, leaving the abandoned military base and climbing towards the mountain.

At about four o'clock in the afternoon, they finally reached the position of the snow line, the altitude here, which was already about 4,500 meters, and from here upwards, the trees began to gradually thin, and the snow under their feet was all year round, although it was not soft to walk, but it was very slippery, and if you accidentally fell, there was a danger of slipping into the valley.

Jiang Ji was at the forefront, leading everyone to walk on the harder snow slopes, he was obviously very experienced, and would often climb up step by step, and then cut crosswise, the biggest advantage of this is safety, and secondly, it can save a lot of physical strength.

But despite this, the people were still a little unbearable to travel at high altitudes, especially with huge backpacks on their backs, so after they entered the snow line, the speed of their travel began to be greatly reduced.

In front of the vast white Gawa Gapu Snow Mountain, has reached into the sky, in the evening, they only rose more than 100 meters, but these more than 100 meters, but almost killed them, everyone finally experienced the pain caused by high-altitude climbing.

Constant coughing, breathlessness, chest tightness, and splitting headaches, all of which made everyone miserable, only Jiang Ji was in a better state, but he was also very tired.

That said, it's not the worst of it.

I don't know when it began, the clouds on the snow-capped mountains began to become thicker, from the original white, quickly turned black, and it was like an endless iron pot, pressing down on them.

At this time, Jiang Ji looked at the sky and hurriedly suggested that everyone should find a stable place to spend the night first, and the sky will change soon.

On the snow-capped mountains, the weather is like a child's face, the four seasons of the day are never exaggerated, at the same time as the dark clouds are pressed down, the wind also begins to rise on the mountain, the wind is getting stronger and stronger, and snowflakes begin to float in the sky.

The snowflakes on the snowy mountains are by no means the kind of beautiful snowflakes, they are completely ice crystals, like sand, hitting the face in the howling wind, it is a pinprick pain, and it is impossible to open your eyes.

The sky also suddenly darkened, and the visibility in front of it dropped rapidly, and in less than twenty minutes, it was already less than ten meters.

Jiang Ji was quite experienced, and in such a harsh environment, he did not panic, but searched as much as he could, when he found that just under the snowy slope where they were, there was a flat land, which was not only leeward, but also spacious, and should be able to accommodate them to camp.

So in the midst of the strong wind, Jiang Ji shouted to everyone and took everyone down the snow slope, and everyone rolled and climbed and hid in the leeward place under the snow slope.

Although the wind was still howling and the blizzard was still raging, they did not dare to stop for a moment, so they quickly took out the tent from their backpack, stuck to the snow wall as much as possible, propped up the tent, and buried the snow nails deep in the snow.

The group set up camp as fast as they could, and then before everyone had time to speak, they all got into their tents.

When Gao Chao got into the tent, he was already beaten by the cold wind, he shivered and got into his sleeping bag, watching the roof of the tent shake violently, making a "whoosh" sound, the wind seemed to tear it to pieces, and people had an indescribable fear from the bottom of their hearts.

I don't know how long it took, but the wind gradually stopped, and it was quiet outside the tent, and there was a dead silence, as if the sound of snow flakes falling on the tent became very clear.

Gao Chao woke up suddenly, he had a nightmare, but he couldn't recall what that nightmare was, in such an environment, he just wanted to have a good rest, but even closing his eyes and sleeping peacefully for ten minutes was also very luxurious.

There was an occasional violent coughing sound outside the tent, and he didn't know who it was, because it seemed like everyone was coughing, and it was already about 4,500 meters above sea level, and it was easy to get altitude sickness here.

Gao Gao's physique is not bad, but he also feels out of breath, and even every time he flips his body, he has to gasp for a while.

The cold hit him, but he had to get out of his sleeping bag because he had to go out to check on everyone, and in the strong wind just now, on such a snowy mountain, there was a good chance that something unexpected would happen.
