That's, the plane.

In this world full of ice and snow, an airplane full of modern technology parked on a block-shaped ridge two kilometers away from Xia Ren and the others. The white paint on the surface of the fuselage almost ignored the past.

Xia Ren and Lanaya looked at each other and decided that no matter what, they would go over and take a look first.

Professor Fold was most likely to be the one who drove the plane over, but after so long, the temperature of minus 40 degrees below zero and 50 degrees below the mountain range at night and the wind speed of more than ten meters per second was enough to freeze any creature who dared to stay outside. They could not tell whether Professor Fold had encountered an unexpected accident or the worst result... Is it possible that he had become a monster?

But that plane was their only hope for survival, and no matter how dangerous it was, they had to try it.

Xia Ren, with the help of Lanaya, took the sled again and came to the ridge. However, the rock walls here were almost vertical and there was no slope for climbing. They had to drive the sled around the rock walls and try to find a road.

Half an hour later, they finally saw a... staircase!

"Can't there be humans living here before?"

Lanaya looked at the narrow stairs, spreading upwards at forty-five degrees to the end of her vision, and she couldn't believe her eyes.

Xia Ren looked at the size of the stairs and frowned slightly.

There is no snow on this staircase, and it is covered with weathering traces. Each of them is about 40 centimeters high, which is seriously inconsistent with the human body. He recalled again the mirage he saw yesterday morning, the magnificent rock city, and its size and proportions are very consistent with this staircase.

That city is probably built by the monsters buried in the snow.

"No matter what, let's go up and take a look first."

Xia Ren said.

They left the sled in place, and the huskys were trained to avoid running around unless they encountered any emergency.

Xia Ren refused Lanaya's support. The ladder was very long and she was not injured. She had a greater chance of survival. Xia Ren had to let her preserve her strength.

His ribs were broken at least three times, so he had to endure great pain every step forward. At the same time, he had to ensure that he had to take every step steadily. Otherwise, if his feet slipped at such a height, he would definitely be smashed to pieces.

It took an hour and a half, and although Xia Ren's physical fitness had improved after spending more than a month in the ice field, he still sweated and most of it was in pain.

Lanaya was not feeling well. The high altitude made the air here thin. She had to breathe harder to ensure the oxygen supply to her body.

When the two finally finished the last step and came to the huge rock platform, they saw the plane parked not far away, and their faces were pale, but none of them could care about the fatigue. Looking at the scene in front of them, they were speechless in horror.

A further away from the plane stands a... city wall!

The city wall is about thirty meters high and is made of four or five rocks. Although the distance is relatively far, they can still see the mottled traces of time on its surface, and they don’t know how long it has existed.

Xia Ren can be sure that what is placed in front of them now is the mirage I saw yesterday morning!

Even Lanaya cannot comfort herself that this is what humans do, and even any rational and sober person cannot agree with it. This magnificent and terrifying building, this building that has never been recorded in history, and this building that is difficult to achieve even with modern technology will be the work of human beings!

Xia Ren barely suppressed the shock in his heart and came to the plane.

The glass hatch doors with only two seats were closed. Without much effort, he found the switch to open it. However, facing this pair of complex instruments and various dense and colored buttons that had been put together, Xia Ren, who had never piloted a plane, was stunned.

"Can you fly a plane?"

He asked Lanaya a little foolishly, who shook his head repeatedly.

"Then there is nothing to do."

Xia Ren inhale carefully to avoid touching the injury and slowly climbed off the plane.

"The plane didn't seem to be damaged, it should have landed normally, but no trace of humans was found around. There was snow below. No one could spend the night underneath without any camping conditions, so we had to go in."

He said, looking at the magnificent walls.

They have to find someone who can fly the plane.

Lanaya was obviously afraid of this rock city, but as long as she was with Xia Ren, she would not be afraid.

This schisand platform is probably just a side door of the city, so the entrance is not too big. The two of them walked in nervously, holding hands.

Only when you are inside these buildings can humans realize their insignificance.

The clear light projected from the ice clouds above the head illuminates the road. There are rocks dozens of meters high around the two. If the scientific research team is here, they can definitely infer the general time of the existence of this city from the surface of the rock. But unfortunately, neither of them is doing research, so they only feel a strong sense of vicissitudes.

Thanks to the previous mirage, Xia Ren learned about the basic situation of the building in advance. Most of the walls inside were in the shape of "right", like a maze made of spliced ​​together, endless. Before they could walk a corner, they used the broken rocks at their feet to make a mark to avoid getting lost.

I don't know how long they walked, but they began to see different buildings, such as ink-colored stones piled together, showing irregular geometric shapes. The two of them were frightened and quickly left quickly. There were also smaller independent buildings with conical, pyramid-shaped, trapezoidal-shaped, separate cubes, cubes aggregates and other cuboid structures. There were also strange buildings in the shape of pentagrams that Xia Ren had seen in the mirage scene. The long circular arch bridge passed through them, and they didn't know where to connect them, and they couldn't know what their effectiveness was. The city seemed to be pieced together by various buildings, and it looked strange, but it might be that Xia Ren and his own wisdom could not fully understand these buildings.

The more you go inside, there are more and more things that are difficult to understand. The stone walls around you that have been exposed to the cold wind for a long time are devastated. It is estimated that in the years ago - perhaps hundreds of thousands of years, or even tens of millions, and hundreds of millions of years ago, they were also glamorous, and the creatures that built them traveled back and forth in it, exuding vitality.

But now they are all turned into ruins.

Xia Ren also saw decorative glyphs on the slightly better preserved stone wall. They were obscure patterns made of lines, just like the existence of this city, and were irrespectable.

Just as they stopped to watch the glyphs on a wall, a sound suddenly came:

"Are you, humans?"
