"Don't sleep, wake up, change the oxygen tank!" Lu Yu hurriedly slapped Ma Lance's buttocks.

The horse got up with a shudder, and scrambled to find the oxygen tank.

The two of them put the oxygen tank under the bed before going to bed, and hurriedly replaced it after touching it, so that they breathed a comfortable sigh.

Ma Li couldn't help but smile bitterly: "It's still a little uncomfortable outside the blue star, dizzy, this broken base station has no heating, and it's cold." ”

When they first arrived on the moon, the two had no experience, and after experiencing this lack of oxygen, they felt that the dangers in the universe were no matter how big or small, and a small negligence could kill here.

This time, the space department prepared 200 cans of oxygen, which could support the two of them to survive on the moon for a month, but before Ma Lance was troublesome, he only brought 20 cans of oxygen to the Great Wall Station.

One hundred and eighty tanks of oxygen remained in the lunar module.

After this lack of oxygen, both men planned to go to the lunar module again and bring back all the remaining oxygen tanks.

Before leaving, Lu Yu inspected the homemade farmland and found that the moon dust and cosmic radiation had seriously affected the homemade farmland, causing it to be unable to grow vegetables at all.

In addition, there are places where water is stored, all of which have dried up, and this Great Wall station can be said to have really reached the point of running out of water and food.

Fortunately, the other internal equipment is still complete, and it can be used to get in touch with the aviation department on the Blue Star.

"Let's go, bring back all the oxygen tanks."

Lu Yu opened the door of the base station and stood side by side with Ma Li, looking at the vast moon, and the time they were in at this time was the positive light time when the sun was shining directly on the moon.

Here, there is no gray, only pure light and pure black.

The dark backlit side of the moon, no one knows what's there.

Buzz Buzz......

The space car restarted, carrying Lu Yu and the two to the space capsule, passing by the crater with the keel before, Lu Yu subconsciously glanced at it, and this glance made him creepy.

In the crater, empty, there is no longer that huge keel!

"The keel is missing?" Ma Lance muttered in shock: "No, is it alive again?" ”

At this moment, Lu Yu and Ma Li both felt an unprecedented horror crisis, which came from the fear of the unknown.

What kind of existence is the mysterious missing keel?

Could it be that living beings have been separated from their flesh and blood, lost their brains and hearts, and can survive in the world with a single bone?

This is not scientific!

Lu Yu held back that curiosity and continued to drive the space vehicle to the lunar module, but when they followed the map marks to locate the lunar module, they found that it was also empty.

The silent lunar dust floating, the endless desolation of lunar soil, and the vanishing lunar module all hammered down on the two of them, making them feel dizzy.

"What's going on! What's going on! Ma Lance unconsciously stepped back two cloths, and then quickly ran forward: "How did the lunar module disappear, where did it go, it shouldn't be, how could it disappear......"

Without the lunar module and oxygen tank, not to mention the oxygen problem, even the return to the blue star has become a problem, and it is abnormal that Ma Lance is not in a hurry.

Lu Yu checked the position where the lunar module stayed before and found that the traces on the ground were clear, so he pulled the horse lance and said in a low voice: "Now there is one thing that can be determined, that is, there must be other creatures on the moon!" ”

"The lunar module has been removed, the traces on the ground are clear, the gravitational pull of the moon is small, these traces are estimated to last for a long time, we will solve the problems of oxygen, water and food first, and then follow the traces to find the lunar module!"

Ma Lance smiled helplessly, pointed to the bloated and fat spacesuit on his body and said: "This suit restricts our movements, with the spacesuit on our bodies, it is a problem for us to bend down and squat, even if we find something to take the lunar module, how can we deal with them?" ”

The special materials and construction of the spacesuit make it difficult for the wearer to bend over or crouch, and in previous years, an astronaut fell on the moon and three astronauts around him were unable to pull him up, and finally transported him back to the base station with some kind of space rover similar to a forklift.

The action is still difficult, let alone a fist and kick fight.

Lu Yu was silent, Ma Lance was right, based on their current state alone, if a battle broke out when they encountered a hostile creature, then any aftermath of the battle could scratch the spacesuit.

In the starry sky, the spacesuit is torn, and if it can't be remedied, there is only a dead end.

Speaking of remedy, how to remedy?

The Great Wall station is about to become a deserted base station!

At this time, the horse lance has no arrogance, after all, the starry sky will not tolerate presumptuousness, it only needs to release a little bit of cosmic rules and attributes, which can give human beings a sense of despair and powerlessness.

"Let's solve the oxygen problem first." Lu Yu looked at Ma Lance, and said with a slight sympathy in his eyes: "Actually, I can temporarily hide in the dark matter plane, where I don't need to worry about oxygen, but you ...... You will die without oxygen. ”

Ma Lance snorted coldly and walked away: "Worry about yourself, it's not your turn to tease me, a little cub." ”

Ma Lance turned his back to Lu Yu, his fingers gently groped his chest, and his eyes flashed with thought, but he finally withdrew his hand.

"Not here...... Where would that be? ”

Lu Yu glanced at the back of the horse lance, and immediately stopped paying attention, he carefully speculated on the direction of the traces on the ground, and found that the traces were always straight, and the end had been extending towards the backlit surface of the moon.

The backlit side of the moon is pure darkness, and with the perception of the human eye alone, going there is tantamount to falling into the abyss.

At present, the problems of water and food are delayed, with the current physique of the two people, they can maintain their physical strength for about two weeks without relying on energy input, and their physical strength will become weaker and weaker after two weeks.

But the problem of oxygen, just relying on the twenty cans of oxygen on hand, it is a luxury to last for a week, and it is expected that on the fifth or sixth day, the oxygen will be exhausted!

That damn Great Wall base station, there is not a tank of oxygen storage at all, and Lu Yu doesn't dare to go to other base stations now, not to mention the long distance, just say that if he goes and doesn't find oxygen, wouldn't it be self-defeating.

"There's no way, I can only follow the traces to see." Lu Yu's eyes flashed with a hint of ruthlessness: "If a battle really breaks out, then you can only rely on the dark matter plane to fight, and the oxygen problem must be solved first!" ”

Ma Lance turned his head and frowned: "You think clearly, if you go, you can't come back?" ”

"It's better than sitting and dying!"

Lu Yu threw down a sentence, and then jumped along the ground tracks, plus he quickly adapted to the gravitational pull of the moon, and disappeared into the last crater in Ma Li's field of vision within a few minutes.
