Ye Han let out a sigh: "Okay! ”

Duan Xu and the others immediately came up with tools, and the three of them worked together to pull out this large ice block more than one meter long from the ice and carefully put it on the lunar rover. Pen % fun % Pavilion www.biquge.info

Such a large piece of ice, at least three hundred kilograms on the earth, but in this place it is only fifty or sixty kilograms, that is, the weight of a soft girl. The reason for being so cautious is that I am afraid that the sharp corners of the ice cubes will cut the spacesuit.

Ice cubes with a hardness of 6, sharp corners are no worse than real blades, and it is not a problem to really cut the ice cubes out of the blade when it is used as a knife.

The spacesuit is made of a combination of multiple layers of materials, and the outermost protective layer has a certain anti-scratch ability, but the anti-scratch is not anti-puncture, so you must be careful when you should pay attention.

To protect the safety of the astronauts, all equipment delivered to the moon is treated with very smooth edges and corners, minimizing the daily wear and tear of the spacesuits.

With the successful experience, the next work became much easier, and Ye Han quickly cut out more than a dozen ice mines, with a total volume of about one cubic meter.

But this is only the volume of the ice mine, in addition to the impurities in the ice body, there are many cavities, Ye Han believes that the cavities in the ice body are left when the ice lake condenses, it may be the water vapor produced by the boiling of the ice lake, which has opened a large number of bubbles in the water that is about to condense.

However, it is impossible for the gas in the bubble to be preserved until now, because after the ice condenses, the temperature of the glacial lake drops lower and lower, and the water vapor in the bubble will only re-solidify due to the severe cold, and it is impossible to maintain the gas state forever.

If all the impurities and cavities in the ice ore are removed, about one-third of the total volume will be removed!

This is still a rich mineral, if you encounter a poor mine, after the ice ore melted, it is difficult to say whether the water you get is enough and the electricity cost is not enough.

The space of the lunar rover was limited, so Ye Han simply asked his two companions to send the first car of ice ore back first, and he stayed to continue mining.

However, at a distance of a few hundred meters, there was no accident at all, and the two people drove the lunar rover away, leaving only Ye Han alone on the ice lake.

Since arriving on the moon, Ye Han has stayed alone for the first time, and his surroundings have suddenly quieted down. The loneliness of the moon is hard to describe, it is the kind of silence that has no sound, death, the breath is like thunder, the heartbeat is like a drum, and even the sound of blood flowing is like a river.

Then he seemed to have auditory hallucinations, first hearing the sound of the ice breaking, then hearing the sound of the breeze blowing, and the most outrageous thing was that he actually heard Bai Xiaoting's vague muttering.

Auditory hallucinations are not a good experience, Ye Han decided to find something to do for himself, started the cutting machine to continue mining ice mines, only to hear the sizzle of laser cutting ice cubes again.

This time it's not auditory hallucinations.

Although the moon has no atmosphere and lacks a medium for sound propagation, the sound can be transmitted to the spacesuit through the ice lake under Ye Han's feet and the cutting machine in his hand, but the cutting sound is too weak to be heard by ordinary people, only in this extremely quiet situation, the extremely sensitive ear can catch a little clue.

People are social creatures, even if Ye Han's nerves are much tougher than ordinary people, facing such an extreme environment alone, he can't help but feel a little uneasy in his heart, even if he knows that there is no one on all sides, he still can't help but look around, and after laughing at himself for being suspicious, Ye Han started the playback function and played some music for himself to break the silent atmosphere.

However, he had turned the volume to the lowest, and the sound of music that had penetrated into his ear drums was still like a constant muffled thunder, which shook him so much that he wanted to cover his ears, and after a few seconds, his ear drums readjusted to the sound of normal intensity, and the sound of breathing, heartbeat, and so on all left him.

Everything returned to normal, Ye Han continued the work in hand, with the previous experience, he is now comfortable operating the cutting machine, and the ice cubes cut out are no longer nondescript triangular columns, but ice cubes close to cubes, and he did not forget to make two holes in the ice cubes as grippers.

This kind of volume does not have to be used by three people at the same time, only one person can be easily handled, every time a piece of ice ore is cut, Ye Han can throw the ice ore aside with one hand, and there is a suitable shape, and the ice can also be stacked together when unloading.

As a soldier, uniformity has been buried in Ye Han's bones, what is the matter with the triangular column without edges and corners?

Cut out another piece of ice ore, Ye Hantuo carefully observed it in his hand, and found that the upper layer of the ice cube had the most impurities, and the lower layer of impurities was relatively few, this phenomenon immediately aroused his interest, and immediately threw the ice cube aside, continued to cut downward, and took out the ice cube from the position more than a foot below the ice surface to continue to observe.

The newly extracted ice cubes were significantly more transparent than the surface ice, and the impurities in the ice were like a fog when the light of the headlamp shone on the ice, and two fist-sized holes in the ice could barely be seen.

Throwing the ice cube aside, Ye Han continued to cut downward, and when it was about a meter deep, the permeability of the ice cube was greatly improved, and the impurities in the ice were significantly reduced.

Ye Han couldn't help but get excited and continued to cut down.

The temporary base only needs water, no impurities in the water, and the ice mine must be processed after it is sent back, and the less impurities in the ice, the easier it is to deal with, and it can also reduce the wear and tear of the water treatment equipment.

So Ye Han dug more and more deeply, and after a while, he cut out an ice pit three meters square and more than one person deep on the ice lake, and threw the ice blocks outside the pit everywhere.

When Duan Zhiyang and Xu Hua returned to the ice lake, they only saw the messy ice outside the pit, but they couldn't find where Ye Han's space was.

It just so happened that Ye Han threw out an ice cube about a foot long on the side of the block and smashed it on the ice pile, startling the two people.

Duan Zhiyang shouted over the radio: "Yezi, what are you doing here?" ”

Ye Han jumped out of the pit: "Don't want the left one, all the right ones are loaded!" ”

"Yo, the two sides are still different?"

"The quality at the bottom is better." Ye Han said, "I'm going to keep digging down." ”

Duan Zhiyang teased: "Lao Gao is digging a wall over there, you are digging a pit here, are you planning to compare the speed with a group and dig an underground base first?" ”

"Do I still need to send ice out to dig the base? Isn't it faster to melt directly at the bottom? Less nonsense, hurry up and load the car, I still have two hours of air, let's transport a few more cars back and see how many days it can be used. Ye Han said.

The temporary base is currently using circulating water, although the treated circulating water does not have any peculiar smell, but every glass of water is a collection of everyone's urine, every time he thinks of this, Ye Han will feel tired from the bottom of his heart.

Don't let me know who invented it!

Ye Han said in his heart.
