Mark felt his heart beat to the limit, speeding up the cliff, constantly magnifying the scenery in front of him and the crack behind him all stimulated his nerves, Mark's attention kept switching between the monitor and the rearview mirror, the collapsed crack seemed to play with them, sometimes pressing, sometimes suddenly slowing down, several times Mark thought he had run to safety, but the crack quickly caught up again.

The speed of the minecart is actually not fast, it can't be compared with the vehicles on the earth at all, Mark's accelerator has been stepped on the end, and the speed of the car can't be raised, so angry that he wants to smash the steering wheel, thinking that even if he drives a triple jumper on the earth, it is faster than it!

In contrast, Nina is much calmer, she has been engaged in geological work for a long time, and has encountered enough similar dangerous events, the moon seems to be calm and comfortable, but when there is real danger, you will see the hideousness under its kind face, in this case, bravery can't save you, the huge crater that is higher than Mount Everest at every turn contains huge energy, such a huge rock collapses, even if the gravitational pull of the moon is very low, it is certain to die.

At this time, only calmness can save you.

Nina knows this well, so she keeps her composure and constantly directs Mark's route, Mark is irritable at first, but quickly regains his senses under her guidance.

"No, throw all the goods away! If it goes on like this, it will be dead. Mark shouted anxiously.

"I don't think that's going to help, there's no heavy loading, it's going to be harder for the car to keep its balance, you throw half of it away."

"Walk you!" Mark slapped the button on the cargo hold, and a large amount of white lunar soil was thrown from the back of the car, like a glowing tail, and the lunar soil flew into a deep crack in the ground, and soon disappeared without a trace, as if it were connected to another world.

At the same time, the same trouble was encountered by their colleagues who were not far away on the gathering mission, and those people were not so lucky, many of them fell into the chasm because of the rampage, and the impact of the car alone was enough to crush people to death, not to mention the rocks that kept collapsing.

And the situation on Mark's side is not optimistic, even if they are lucky, they are quickly pushed to a dead end, the speed of the ground collapse is gradually accelerating, and the sudden horizontal crack in front of Mark forced Mark to stop the car, and they are surrounded by cracks in all four directions, and they can feel the obvious vibration when sitting in the car.

The earth is roaring, this cold and lonely land shows the other side of its rage, humans always easily think that they are in control of nature, climb a mountain and think they have conquered a mountain, but this behavior is like a flea on your head, shouting that you have conquered humans, this land that people think is so familiar, still devours a dozen lives in an instant.

"What are you doing in a daze?!" Nina decisively opened the door and took out the kit from under the seat.

"Huh?"

"Jump!"

When Mark was at a loss, suddenly a pair of hands grabbed his arm and dragged him out of the car, Nina kicked the top of the car violently, and the bodies of the two people floated into the air together, and soon the car was engulfed in the dark gap, and the white mysterious cube in the sky was floating there silently, as if staring at each other with the abyss on the ground.

On the moon, people can jump more than four meters high at will, and everyone is a high jump champion here, but this is not enough to get Mark and Nina out of the dangerous area, and the two of them still fell into the depression, but fortunately, Nina nailed the wall with the small mining manuscript in the toolkit, and the two slowly stopped falling, and Mark came back to his senses only to find that he was hurriedly hugging Nina, and the scene became a little embarrassing for a while.

"There's another one, you can just climb down the wall like me." Nina tossed the kit down to Mark.

"Oh, okay." Mark said as he took out his tools and nailed them to the rock wall, although he didn't feel anything through the hazmat suit, but the position was really terrible.

There are rocks on it that keep falling, it's not a good idea to lie here all the time, the two of them have to move down a little bit, the low gravity allows them to easily complete the movements of some rock climbers, but Mark doesn't remember handsome at all, although they escaped, but they are not out of danger, the protective clothing they are wearing now can't fight the cold of the moon at all, Mark has already felt that his fingers are starting to freeze, if he doesn't want to find a way to keep warm, he may freeze into an ice sculpture here, Then tomorrow when the sun rises, it will be thawed and scorched again, and after a million cycles, it will turn into an indescribable mass of mud like a molecular dish.

There was an abnormal shock from below, and Mark didn't know if it was his own car that blew up, or if it was some other unlucky car, anyway, if he had just fallen off one piece, it should have been wiped out with this explosion by now.

After about ten minutes, Mark and Nina finally descended to the bottom of the rift, which looked like a narrow river valley, but it was drained, narrow at the top and wide at the bottom, and the bottom was flat and smooth like a riverbed, Nina turned on the searchlight above her head, and the world in front of her quickly became brighter.

"What is this place? Was it because of an earthquake? It doesn't close suddenly, does it? Mark remembered a scene from the cartoon where the grave robbers stepped on the trap and the stone walls on both sides quickly closed and crushed them into meatloaf.

"Probably not, the geology here has existed for tens of thousands of years." Nina leaned down to take a closer look, "This place is like a big water pipe, with a thin stratum on top and a hollow inside, which must have collapsed because of our recent large-scale drilling." ”

"Does the government know this?" Mark asked.

"I guess I know that this mine was shut down a few years ago because of unknown geological movements, and now they have to take risks in an emergency." Nina picked a small rock and put it in her fanny pack, and looked up at the farthest point that the searchlight could reach, the valley-like passage leading into the distance, and the end of the vision was still dark.

"Damn! It's just a matter of carelessness! It's not risking their lives! Minsk is really not a good thing! Mark scolded indignantly.

"Don't say it's useless, let's go and explore, staying here won't come to rescue us." Nina was not at all afraid, and walked ahead of Mark and stepped into the dark passage.
