Die on Mars

Tang Yue sat in the dung pile and used scissors to cut open the vacuum packaging of the stool. Due to dehydration and low temperature, the feces in the bag were all dry and brittle. It looked hard, but in fact it would break like sand if lightly pounded.

At this age, he never thought that he would be lucky enough to have close contact with feces in his life. In the past, Tang Yue would pull up his pants, flush the toilet, and leave. He was quite ruthless and never looked back.

Tang Yue poured the dry feces in the vacuum bag onto the iron plate. He could even tell what he had eaten that day based on the food residue in the feces. Many foods rich in crude fiber cannot be fully digested in the human stomach. , will be excreted together with the feces. Tang Yue often ate canned vegetables for a while, and incompletely digested plant fiber was often seen in the stool during that period.

Tang Yue wore two layers of masks. Fortunately, the stools had been drying for a long time and had no smell.

"The smell in feces mainly comes from 3-methylindole, which is skatole. If this stuff gets on your clothes, it will smell like shit." The old cat sat on the side to help. Mash the feces and say it.

Tang Yue felt that its greater interest lay in the feces itself.

"Tang Yue, look at this lump. There is a long thing in it...is it a roundworm? No, it's undigested fiber..."

"Tang Yue, did you eat vegetables today? I saw vegetable leaf residues. Do you know this is food waste? I think these vegetable leaves can still be eaten after being picked out."

"Tang Yue, are your gastrointestinal function and digestion not good? Wuwuwuwu..."

Tang Yue clapped his hands and turned around.

He had just stuffed a rolled-up glove into the old cat's mouth.

It finally stopped.

"Human and animal manure is a very traditional fertilizer. It is rich in nitrogen, phosphorus, potassium, calcium and other elements. It is very suitable for growing vegetables. They can provide sufficient nutrients for tomatoes." Ophiopogon japonicus's voice sounded in the headphones, "Tang Yue, you These dried feces need to be rehydrated, that is, water is added, stirred thoroughly, and then mixed with the soil taken.”

Perform rehydration...

Tang Yue began to sweat on his forehead.

Although Maidong talks so academically, isn't this behavior just... stirring up shit?

Tang Yue glanced at the iron drill in his hand. The purpose of a stick depends on who is holding it. If it is in the hand of Harry Potter, then it is a tall wand. If it is in Tang Yue's hand, it will be a tall wand. Go on...it can only be a shit stick.

Origin determines everything.

Tang Yue asked the old cat to bring over the condensed water last time. Ophiopogon japonicus did not explain how much fresh water should be used. She only described that "the water added should make the feces sufficiently softened and diluted. The viscosity is between thin soup and thick soup." Between the porridge, it should be like a pot of curry with a little too much water.”

"Then the feces is added to the soil matrix, like curry on rice."

This metaphor is truly incredible.

Tang Yue never wanted to eat curry rice in his life.

Since this is a preliminary experimental planting, neither Ophiopogon japonicus nor Tang Yue is prepared to use up all the tomato seeds. If it fails accidentally, it will be doomed. Tang Yue decided to plant only about ten tomatoes in the first batch to verify the feasibility of the plan. When he was 100% sure, it would not be too late to sow the remaining vegetable seeds.

Therefore, the soil and feces were prepared according to the amount of ten tomatoes. Tang Yue still had a lot of poop in his hands... On the desolate Mars, poop was indeed a valuable and scarce resource.

Tang Yue imagined that if there was a primitive farming civilization on Mars, poop would be a hot commodity. Maybe someone would make a fortune by collecting and hoarding poop.

Lao Mao and Tang Yue each wore a helmet on their heads, as if facing a powerful enemy.

The old cat held a sink in his hand, which contained ice water.

Tang Yue held an iron skewer tightly in his hand and placed a large beaker in front of him. In the beaker was dark brown mysterious powder and lumps.

"Are you ready?" Old Cat's eyes were determined.

"Ready." Tang Yue nodded.

The old cat tilted the sink and poured water into the beaker. The feces in the cup was washed away, and the water immediately became turbid. The black residue mixed with foam swirled and floated up. The water was quickly absorbed by the feces, and the dry powdered stool became sticky again. It thickened like a jar of mud. Tang Yue held his breath, inserted the iron skewer in his hand into the stool, and began to stir it vigorously.

Tang Yue comforted himself that he was a happy manure digger.

"Tang Yue, just think of it as black sesame paste." Ophiopogon japonicus said.

Tang Yue and Lao Mao were both suffocated.

"Sister, I beg you to stop talking. You have already harmed the curry rice, please don't harm the sesame paste again!"

Maidong was wearing blue overalls and a matching hat, floating in the core cabin of the Crystal. The screen in front of her was connected to the Kunlun Station's communication system, and there were densely packed control panels on the front, back, left and right.

Maidong never dared to turn off the communication system. She was worried that Lao Mao and Tang Yue on Kunlun Station would disappear as soon as they woke up, just like on Earth.

Only when he looked at that mean man and cat did Maidong know that he was still alive.

Living alone in a space station is boring and boring. Although the universe is vast and boundless, being in a small space station can make people feel claustrophobic. The core cabin of the Crystal is the largest and most spacious cabin in the United Space Station, but going back and forth It's only a few steps long. The other cabins are less like rooms and more like pipes, cylindrical or rectangular pipes. Walking through these pipes feels like traveling in a maze or an ant nest.

Ophiopogon japonicus' daily life is very regular, including physical training, eating, checking the work of the space station, taking care of plant samples, and finally sleeping. She only sleeps five to six hours a day. She is in low-Earth orbit and does not distinguish between day and night, so Ophiopogon japonicus often suffers from insomnia. .

After all the scientific research work was cancelled, the free time was used by the girl to rest and have fun. There was a lot of music, movies and video games in the space station, and there was even a set of Sony's special edition PS10 game console. This game console was brought by Laotang. Coming here - each astronaut is allowed to carry a certain amount of personal belongings. In addition to necessary supplies and scientific research equipment, scientific expedition team members are allowed to carry a certain weight of personal belongings. You can bring dolls, photo albums, and even vinyl. Records, as long as they don't violate safety regulations.

In order to relieve fatigue during the long journey, most people brought entertainment supplies, such as more than a dozen terabytes of movies and music - except for Lao Mai, who was 250 years old and a math madman. He brought a large pile of scratch paper and declared To overcome Goldbach's conjecture during the Mars mission flight.

Of course, he forgot this ambition as soon as he got on the boat, and happily started playing Elder Scrolls and Call of Duty with Lao Wang.

Maidong doesn't play games. She listens to music and watches movies in her free time. There are many very classic old movies in the space station. The girl is not interested in those weird special effects blockbusters made by Hollywood. Since the earth disappeared, Maidong has been there. I watch "Gone with the Wind", "The Hunchback of Notre Dame" and BBC documentaries repeatedly, imagining that the blue planet is still 100 million kilometers away.
