"What's going on?" I said puzzled.

"Don't move around and save a little physical strength, this thing bullies men and women, fat and thin, tall and short, and quiet. We call this altitude sickness, and we should be almost in Devil's Town after today. You should be able to adapt to it, and you will have this reaction at an altitude of more than 3,000 meters. It seems that the altitude is too high and the oxygen is not enough, and you think about the three cities of Utopia are all in the newly defined zero altitude area. And this devil's city is 3,700 meters above sea level, can it not be uncomfortable? It's okay to get used to it in a week at most, I threw up when I first came. You're doing a good job, and you're comfortable getting used to it. Han Dong said.

Early in the morning of the fourth day, the train stopped.

The guards pressed us all out of the car, and as soon as we got out of the car, we were almost deserted.

It was full of yellow sand and rolling dunes, and I was a little dizzy when I came down.

The sea seems to have recovered, constantly looking in the direction before the train came.

The guard seemed to see something and said, "Don't try to escape, you saw it too." It also takes four days to get on the train back and forth, how long do you think it will take? Or walk in this desert? ”

We were escorted a little further on, past a slightly larger sand dune.

I was shocked after the sand dunes, and it was the rock walls that stood in my way.

It's like a wall where you can't see the head, and there is a wooden platform on top of the wall below.

You can see people with tools mining the rock wall, and the wooden platform is about nine floors. Each of the nine floors goes from the far left to the far right, and the rocks are constantly being chiseled down and carried away.

Han Dong said: "This is the moon, and only the rocks on the surface of the moon have helium-3. There isn't one inside, so we need to chisel off the outer shell of the moon. The wooden platforms are numbered as Wood 1 to Wood 9, and I first came here two years ago. At that time, it was only opened to Kihachi, and it will only get harder and harder to mine as time goes on. Look below is the Devil's Town, the only oasis. ”

The guards pulled us and started to go down, and I saw the Devil City that Han Dong was talking about.

It was indeed a desert oasis with trees and lakes.

In the middle, a vaulted grotto is reinforced with wood and steel frames, and the castle looks like a skull.

We were taken down and walked for a long time before we came to the level.

By the time we entered the Devil's Town, it was already dark.

Workers in the distance also began to be transported back by slightly larger vehicles, and came to the gate of Devil's City.

The guards swapped us with the guards of Devil's City, and it looked like the two sides were handing over.

The exiled workers who came down not far away had already entered the Devil's City, and they passed by and greeted us in the process.

"Newcomers."

"It's a little bit rare this time."

"Old Han, you're back. I'll tell Brother Shi that he is happy. ”

"Old Han, you're coming later than you asked. Brother Shi has been angry recently, so be careful when you give the goods. ”

。。。

"Who made Brother Shi angry?" Han Dong shouted.

The guards of Devil City knocked on Han Dong with a stick and said, "Don't talk to each other. ”

It seems that the guards of Devil's City are even more fierce than the ones who sent us.

After the handover of the guards, he asked about the next train to leave.

The Devil City guard in front of him took out the key and shouted, "Come, untie it for you in order." ”
