Three days later.

The Tianzhou 37 cargo spacecraft slowly landed on the sand, the thrust reverser engine roared and raised the sand and dust that covered the sky, at a distance of more than fifty meters, the sound of the rocket engine should have roared like thunder, but the too thin air weakened the noise, and in Tang Yue's ears, there was only a walk-behind tractor outside.

He turned his head to look out, the white and rounded fuselage of the cargo spacecraft was particularly conspicuous in the brown-yellow dust, Tang Yue could even see the blue letters on the fairing: CNSA, and he also saw the old cat, the small shadow standing in the dust, guiding the spacecraft to land on the landing field, the fur was turned by the air flow of the engine.

This is the first time Tang Yue has seen a man-made object again after the disappearance of the earth, the Tianzhou spacecraft is undoubtedly a curvaceous whole, like a huge warhead, it is a one-time spacecraft, and it cannot take off again after landing, so it is not divided into upper and lower levels, the white and smooth fairing shell reflects the sunlight, the spacecraft slowly unfolds the landing gear, and the engine is turned off at the last few centimeters of landing, and the spacecraft stands steadily.

Everything was perfect.

The spacecraft traveled hundreds of millions of kilometers in the dust, and without any human guidance and interference, the final landing site was only five meters away from the intended location.

The old cat lowered the ramp and elevator in the cargo compartment of the spaceship and began to unload the cargo.

They had been waiting for this spaceship for too long, and it brought hope for the survival and continuation of the Kunlun Station.

Tang Yue should have been very happy.

He had eaten compressed biscuits and tomatoes for more than half a year, and now he finally had canned beef and Australian lobster, which in the past was simply the New Year.

But he watched from afar as the Tianzhou spacecraft landed on the ground, but he couldn't make the slightest wave in his heart, and he even refused to invite the old cat to unload the cargo with him.

He doesn't like to eat lobsters anyway.

Tang Yue sat on the chair, his eyes fell on the monitor on the desktop, a little dazed, he often couldn't help but be in a daze in the past three days, and his brain was so tired that he didn't want to turn.

On the computer monitor is still the orbital equation he calculated three days ago, they tried everything to design a rescue plan, but fate did not give them a chance to implement it, he did not understand why the space station crashed, the old cat said that you give you a seven-fold discount on the number that Mai Dong reported to you, which is the true height.

This cat knows everything.

But it doesn't say anything.

This is the style of artificial intelligence fucking people, they always remain rational, always choose the best result, the old cat probably predicted the final result on the day of the accident on the space station, it was the one who peeked at the dice points in the cup, but it told Tang Yue that the lid was not opened so he didn't know.

When the old cat is designing a rescue plan, what is it thinking in his heart? It constructed a set of plans that were impossible to implement with completely false data, and then pretended to advance step by step, and it advanced so rigorously and meticulously that Tang Yue believed it from beginning to end.

It probably despaired.

Sooner than everyone else despaired.

Tang Yue still maintains the habit of wearing headphones at any time, Tang Yue turned over the last recording and listened to it repeatedly, listening to it without saying a word, not crying, not making trouble, and the old cat did not bother him, Tang Yue did whatever he wanted, the old cat knew very well that this depression was temporary, time would eventually dilute everything, no matter how important and unforgettable the person was, as long as it was a long time, it would eventually be blurred in the years - this is the self-protection mechanism of the human brain.

But it's a pity that the old cat doesn't have this mechanism, and no matter how long it has been, the crash of the space station will seem like yesterday to it.

Every day it wakes up from its dormancy, it can recall that Mai Dong told it yesterday to take care of Tang Yue.

So it has to take care of Tang Yue.

With a "click", the hatch of the airlock room opened, and the old cat dragged the heavy box into the door, and then opened the seal, the box was full of soft cans, the Tianzhou 37 cargo spacecraft brought rich supplies, it was loaded according to the needs of six people, from food and fresh water to medicine, enough for Tang Yue to eat alone for a long time.

The old cat went back to unloading, piling the boxes in the landing field, and then pulling the small cart back and forth, organized and unhurried, except for food and fresh water, everything else was stored in the garage.

"Class A canned food...... Sixty pieces. ”

"Class C canned food...... Eighty pieces. ”

"Category E rehydrated food, thirty kilograms."

The old cat carried a small notebook in his arms, counting the materials one by one, and there was a kind of relief that the old farmer had harvested the crops.

The Tianzhou spacecraft landed at 10 o'clock in the morning, and it started working at 10 o'clock and worked until half past eight in the evening, going back and forth between the cargo spacecraft and the Kunlun station, watching the supplies gradually pile up in the hall, and never tired of it, until the power was close to running out.

The old cat plugs himself in the charging cable.

"Old cat."

Tang Yue's throat was hoarse, he hadn't spoken for a whole day.

"Huh?"

"I'm so tired."

"When you are tired, lie down and rest." The old cat said.

Tang Yue shook his head.

"I can't live anymore."

The young man turned his head to look at the old cat, the latter was taken aback, Tang Yue's face was pale and withered, and he looked like he had lost half a catty—something had collapsed in his body.

"Old cat, I really ...... That's it. ”

God knows how Tang Yue has persevered until now, the earth has disappeared, if it were a different person, I am afraid that he would have had a mental breakdown, but Tang Yue can still muster up his spirit to face the life that is getting worse day by day, saying that he is strong-willed, optimistic, or a tendon in his brain, after all, he supported this small residence on Mars on his own.

But now even Tang Yue has reached the limit, the space station has crashed, Mai Dong is dead, his only spiritual pillar has collapsed, the world is vast, and he is finally left alone.

He will not survive for the sake of survival, and in this case, it is only endless torture to live any longer.

The old cat was silent, it looked at the abundant materials on the floor, Mai Dong had told it to take good care of Tang Yue, but if even Tang Yue himself gave up survival, then what could it do? It couldn't tie Tang Yue up and stuff food into his mouth with a mallet every day.

"Is the grave we dug still there?" Tang Yue asked.

"Yes."

The conversation ended, no one spoke again, and there was silence in Kunlun Station, only the clock beating minute by minute.

Tang Yue sat in a chair, the light above his head casting his shadow on the floor, he was the last human in the world.

The starlight outside the window.

The world is lonely.

"Knock knock!"

Three muffled sounds broke the silence, and Tang Yue, who had been in a daze, was stunned for a moment, and didn't react for a moment what kind of sound it was and where it came from, but in the next second, he thought he was hallucinating, because he followed the source of the sound and subconsciously looked over and found that it came from the inner hatch of the airlock room - and the next second, Tang Yue turned back sharply to find the old cat.

At the same time, the old cat also turned its head to stare at Tang Yue, one person and one cat were confirming that the other party was indoors.

Tang Yue and the old cat were both stunned, their eyes widened, and they exchanged quickly and silently with their eyes.

Tang Yue: Hallucination?

Old Cat: Hallucinations?

Tang Yue: Hallucination!

Old Cat: Hallucination!

Just when Tang Yue and the old cat were glaring at me and I was glaring at you, there was another knock outside the cabin door in the airlock.

"Boom! Boom! Boom! ”
