Tang Yue forcefully inserted the shovel into the soil at the head of the pit, and the long handle erected looked like a tombstone.

Although it was said that he was going out to carry out his daily routine work, in fact, Tang Yue started digging a pit with a shovel after moving the battery panels. He picked a feng shui treasure place, not far from the Eagle spaceship, the terrain is flat, there is a shallow ditch in front, there is a hillside behind, in feng shui this is called "there is a photo in the front, there is a back", it is a suitable place to bury people. Guo Pu, a feng shui master of the Jin Dynasty, said in the "Book of Burials" that "the law of feng shui is the best for water", I don't know if this set can work on Mars, this ghost place has run out of water tens of millions of years earlier.

Tang Yue dug a shallow pit, he measured it with the step size, it was about two meters long, half a meter deep, and it was more than enough to lie down and go in.

This is the tomb he prepared for himself, in case one day Tang Yue is really paralyzed and falls to the ground, he will climb into this pit to lie down, and then cut off the oxygen and electricity of the Mingguang armor, and die quietly without anyone knowing.

Tang Yue sat down, looked around, and felt that the view was quite good lying in this place, not far from the left was the Eagle spaceship, and on the right was Kunlun Station, the three old guys were not far from each other, and they could still take care of each other. It is conceivable that after Tang Yue's death, his corpse should be kept for a long time in low temperature drying, and if the extravehicular suit is opened, it won't take long for Tang Yue's corpse to dry like wood.

As for the epitaph or something, there is no need to write it, no one will see it anyway. From the moment the earth disappeared, it no longer mattered what Tang Yue's name was, he was the only earth creature on this planet, Tang Yue no longer needed his name as a code name to distinguish himself from others, he was unique in himself.

Tang Yue got up and returned to Kunlun Station, and he didn't pull out the shovel, so he left the shovel here as a mark, so as not to find it difficult to find it in the future.

What kind of person would use a shovel as his own tombstone?

That's probably the last person in the world.

When Tang Yue returned to Kunlun Station, Mai Dong was already scanning pictures, and the number of satellite photos had risen from 4,000 to 4,500, and searching for the traces of the old cat had become Mai Dong's daily routine.

"Good morning Tang Yue, is it so early today?" Mai Dong's eyes took off the screen, "Today's work is done?" ”

"Good morning." Tang Yue nodded and paused for a few seconds, "Mai Dong, I may not live long." ”

The girl's hand shook.

"You...... What are you talking about? ”

"After the Earth disappeared, I lived a long time in a state of confusion, living like a walking corpse." Tang Yue took off his Mingguang armor, sat down on the chair, rubbed his hands together to keep warm, "I don't know where I am, I don't know what I'm doing, and I don't know what the meaning of my life in this world is...... Anyway, the earth is gone, and the seven billion people are gone, so what difference does it make if there is one more or one less? ”

"I don't dare to think about the earth, I don't dare to think about the people on the earth, I can only numb myself in the repetitive work day after day, because I am afraid that I will collapse." Tang Yue whispered, "Can you experience that feeling of hopelessness in life?" I used to think that God had let me survive, maybe there was something on my shoulders, but then I thought I might just be a pile of kitchen waste, forgotten in the corner of the universe. ”

Tang Yue...... Don't think so, as long as we live, there is hope. ”

"There's not much hope, I'm in terrible shape." Tang Yue shook his head, rolled up his sleeves, and let Mai Dong see the bruises and blood spots on his hands, "I am bleeding under the skin all over my body now, this is a sign of scurvy, maybe in another half a year, I will be paralyzed, once I lose my mobility, it will definitely be better than death, if it really comes to that day, I will take the initiative to end my life...... I've dug up the grave. ”

Mai Dong covered his mouth with wide eyes.

"I picked a feng shui treasure, the green dragon on the left and the white tiger on the right, gathering the essence of heaven and earth, if my body does not rot for thousands of years, maybe it can become a big zongzi." Tang Yue smiled, "Then crawl out of the grave and jump around on Mars." ”

"It's not funny at all!"

Tang Yue gradually restrained his smile, put his palms together against the tip of his nose, and sighed deeply.

"Sometimes I lie in bed, looking at the roof, and I can't sleep for a long time, and I wonder when is this the end of the day? What is the difference between dying one day earlier and dying one day later, and dying two years later and dying tomorrow? ”

Mai Dong lowered her head slowly, she didn't know how to answer Tang Yue, her own situation was exactly the same as Tang Yue, for this young girl, when would such a day be a head?

"But I can't die yet, and if I die, what will you do? What about the cat that sees only ghosts? Tang Yue smiled, "How can I leave you alone?" ”

Mai Dong bit his lip and nodded.

"So I'm going to save myself." Tang Yue raised his head, gritted his teeth and said, "Whether the old cat can come back or not, whether the temperature control system can be repaired or not, I must save myself!" ”

He decided not to wait for the old cat any longer, and it was still unknown whether the old cat would come back.

He's going to do his last bit to save himself!

Scurvy is currently the biggest threat, and the only thing that can alleviate and cure scurvy is vitamin C, which is very common on Earth, and is abundant in almost all vegetables and fruits, but it is extremely rare on Mars, and can only rely on external supplies.

Outside supplies have long been cut off, and the multivitamin tablets in Kunlun Station have been exhausted, and the most viable and sustainable source of vitamin C is fruits and vegetables.

Mai Dong left a sufficient number of tomato seeds in Kunlun Station, and if Tang Yue could successfully plant them and wait for them to sprout and bear fruit, then the lack of vitamin C could be alleviated and Tang Yue's scurvy could be cured - but the damage to the temperature control system caused the room temperature at Kunlun Station to drop significantly, which is the biggest problem when growing tomatoes.

"Tang Yue, is there any way you can maintain the temperature?" Mai Dong asked.

"Nope." Tang Yue shook his head, "But now I can't care so much, take one step at a time, and become a dead horse doctor...... Is it true that the minimum temperature should be 20 degrees Celsius? ”

Mai Dong nodded, "Tomatoes are temperature-loving vegetables, and the optimal growth temperature is twenty to twenty-five degrees Celsius, but it doesn't matter if it's a little lower, but the growth and fruiting speed will be slower." ”

"I try to find a way to give them an ambient temperature of twenty degrees." Tang Yue took a deep breath and swept his gaze over everything in Kunlun Station, at this time, you can use whatever you have, you can't manage so much wasted resources, it's a big deal to drink less water and use less electricity in the future.

"But Tang Yue, it will take at least two months for tomatoes to bear fruit from planting to fruition." Mai Dong reminded, "What should I do in these two months? If you don't take vitamin C supplements in time, your physical condition will continue to deteriorate. ”

"Yes, tomatoes take time to grow, so I had to find a temporary source of emergency vitamin supplements."

"An urgent source of replenishment?"

Tang Yue nodded, took out a pack of compressed biscuits from the cabinet, and shook it at the camera, "This is it." ”
