Die on Mars

The old cat didn't know how to collect fresh water with a shovel, and the many functions of a shovel quickly flashed through his mind.

fight.

Chop.

Dig a hole.

Shovel.

And fried eggs.

Taken together, the purpose of the shovel should be like this - fight with Tang Yue, kill Tang Yue with a shovel, then dig a hole and shovel dirt to bury him, and finally sit on the grave and fry an egg with the shovel.

But what does this have to do with collecting fresh water?

While the old cat was thinking, Tang Yue had already started spinning around with a shovel. He looked down at his feet and walked around near the Eagle spacecraft. As he walked around, he used his feet to test the sand underneath. He seemed to really want to find it. A place to dig a hole.

"Old Cat, here, come here!" Tang Yue walked five or six meters away, put a long-handled shovel on the ground, turned around and called Old Cat.

The basalt was too hard to dig with a shovel. Tang Yue found a place without large rocks under his feet. The upper layer of this area was gravel, and the lower layer was soil mixed with fine sand. Tang Yue poked hard with the shovel to determine the manpower. If you can dig it, you can invite the old cat to dig the hole together.

"How big of a hole do you want to dig?" The old cat stood on the edge holding a shovel - its height was not much higher than the shovel.

Tang Yue lowered his head, opened his hand and gestured, then used a shovel to draw a circle on the sand, "Well... first dig a hole one meter in diameter and half a meter deep to see."

The old cat glanced at him, "You go back first, don't waste the Mingguang Armor's oxygen and electricity here, I will dig this hole."

"No." Tang Yue sternly rejected the old cat and picked up the shovel, "Let's dig together, it will be faster this way!"

ten minutes later.

Old Cat: If you are still going to use the shovel as a spoon in your next job, I suggest you go back now.

Tang Yue:......

Tang Yue returned to Kunlun Station.

"Tang Yue? Why did you come back first?" Maidong asked, "Where is Mr. Cat?"

Tang Yue closed the door of the airlock, removed the life support system, and took off the Mingguang armor.

"The old cat was digging a hole outside. He said I didn't know how to use a shovel, saying that I used a shovel just like a spoon, so he drove me back... But he didn't even think about it. I was wearing Mingguang Armor. You can't even bend down, how can you be as flexible as it?" Tang Yue pouted.

"Dig a hole?" The girl was curious, "Why dig a hole?"

"We are going to dig a grave and build a tomb for ourselves." Tang Yue said, "Whenever we can no longer survive, we will lie down in it..."

Maidong's expression suddenly changed.

Tang Yue knew that he had said the wrong thing.

"Collect fresh water." He quickly changed his explanation and explained, "The purpose of digging the pit is to collect fresh water, because growing tomatoes and carrots requires water, and the water we have is not enough... We are not planning to use the Eagle spacecraft to descend the stage. Does the propellant react to make water? But the product of the reaction is water vapor, and we now need to collect it."

Maidong breathed a sigh of relief.

What she fears most is that something happens to the person and the cat in Kunlun Station.

"Have you finished today's work?" Tang Yue asked, "How is the status of the space station?"

Maidong nodded, "I just came back from a circle and found that a piece of insulation lining fell off in the cabin. I used transparent glue to stick it back. There is no problem with other cabins... But the Dawn cabin still can't Going in, I still haven’t found where the crack in the cabin is.”

During a supply transport mission three months ago, the Eagle spacecraft had a violent collision with the United Space Station, which caused serious damage to the Dawn module and cracks in the outer wall of the module. At that time, Laomao closed the hatch in time, cut off the air circulation, and cut off the power supply, thus preventing the entire space station from losing pressure. However, Maidong was alone on the space station and was unable to repair the damaged Dawn module.

In the past three months, Maidong, under the guidance of Lao Mao, tried to enter the Dawn cabin.

She put on the spacesuit inside the cabin and put on the life support system, then closed the door at the other end of the crystal cabin, first isolating the air flow between the crystal cabin and other cabins, and then opened the Dawn's door.

The moment the crystal cabin was connected to the Dawn cabin, air began to leak.

The cabin of the Dawn, which had been dead for two months, was pitch black, completely in a state of cold vacuum. After entering the Dawn cabin, Maidong closed the door behind him, and then began to try to find the crack.

This crack is difficult to find. It is on the outer wall of the space station. Maidong cannot directly see the outer wall. The cabin has a thick lining, as well as densely packed experimental boxes and control panels. If you want to repair this crack, you must first find the exact location of the crack, and then remove the instruments and lining in the cabin. It is extremely difficult and the workload is huge. Maidong cannot complete it alone... The girl wandered around the Dawn Cabin and searched. After two hours, the old cat finally called me back.

Maidong once proposed that external repairs could be carried out, but Lao Mao gave up the idea after considering the difficulty and danger.

Today's joint space station has completely abandoned the Dawn module. Fortunately, the absence of this module does not affect the normal use of the space station - the main functions of the Dawn module before were deep space observation and high-energy physics research, and these two functions are no longer needed. .

"Tang Yue... these days, I have been thinking, if the earth really disappears, can we, as the last two human beings in the universe, do something?" Maidong said, "For example, make a record to provide information to human civilization. Leave a little legacy behind.”

"record?"

Maidong nodded.

Tang Yue asked: "Do you mean to write a memoir? Write a memoir for the entire human civilization?"

Maidong then nodded.

"At least we can leave something behind, otherwise in the end, even we will be gone, so what else can prove that the earth and humans once existed?"

Tang Yue thought it was a good idea to write a memoir of all mankind, review the development of human civilization, and make a summary of the survival of all mankind - although this is God's job, he may not have this level and qualifications, but now There is no one else besides Tang Yue who can do this.

Finally, give it a high-end and atmospheric name, such as "Once Upon a Time on Earth" or something like that.

This is evidence that human civilization once existed.

Let this universe never forget humanity.

We once existed.

No matter where the end is, we are trying to survive.

"But I'm not very good at studying history..." Tang Yue scratched his head. As a pure boy majoring in science and engineering, he had some idea about the Qin Emperor and Han Dynasty warriors, but he knew nothing about the dynasty changes in ancient Egypt.

There is no doubt that spreading the legacy of human civilization is an extremely huge project. It cannot be completed by Ophiopogon japonicus and Tang Yue alone. They can only do whatever they can.

"If you don't understand something, you can ask Mr. Cat." Maidong reminded, "Mr. Cat must know."

"Yes, if you don't know something, just ask the old cat." Tang Yue turned to look out the window. In the distance, the little white cat under the Eagle spacecraft was digging a hole with a shovel.

The old cat threw the shovel to the ground and climbed up from the pit.

"Tang Yue——! The hole is dug!"
