"The air tightness is intact, and the internal pressure is 42kPa."

Tang Yue twisted the lock on his wrist, with a gentle "click", the gloves were engaged, and the green light turned on.

"The HUT function is intact, the shoulder joint is normal, the elbow joint is normal, the wrist joint is normal, the lower limb joint is normal, and the LTA function is intact."

"The life support system is normal, the liquid cooling is normal, the average heat discharge is 300W, the temperature in the suit is 22 °C, and the oxygen circulation flow is 17L/n."

Tang Yue tapped on the control terminal on the back of his hand, and the diffraction images on the glass mask quickly switched, and Tang Yue reported in turn.

"The battery balance is 97%."

"CCA is normal, communication channels are normal."

Tang Yue stretched out his hand and pressed the unlocking button on the door of the airlock room, a subtle fan turning sound sounded, and the air pressure in the airlock began to rise, and finally it was the same as the Kunlun Station hall room.

The lock cylinder exited, the hatch slowly opened, Tang Yue turned around, and glanced at Kunlun Station for a long time.

The hall was neatly tied, the workstation case was placed under the table, it had been turned off and unplugged, it was finally free from the clutches of the old cat, and no one would ever exploit it again, the computer monitors were placed back to back on the table, the chairs were lined up against the wall, all the paper materials were put into drawers, the tables were clean, and even the cups and clocks were placed in a line, like a boys' dormitory facing a bed during military training.

The OGS system is still on, but it is running at the lowest power, the old cat once said that it can last for fifteen years, Tang Yue doesn't know if this is true, but as long as the OGS system is still running, then all life in Kunlun Station can survive.

The plants sat high on the shelf, Tang Yue and the old cat made a simple dropper device with rubber pipes, led the fresh water in the water tank of Kunlun Station for irrigation, and filled all the soil and fertilizer into the petri dish***The living space of the eggplants expanded.

Tang Yue's gaze swept over the leafy tomatoes, each of which stayed for a long time.

The one that grows the most is the boss.

Next to it is the second child.

There are also third, fourth, fifth, sixth, seventh, eighth, nineth, tenth, and eleven.

This time Dad is going to go away.

You're going to far, far away, you're going to fight a very difficult battle, and you have to take care of yourself.

Okay.

"Here's the Martian Stray Dog, Roger." The voice of an old cat came from the headphones.

Tang Yue turned around and stepped into the airlock room, the hatch slammed shut behind him, and it locked with a click, and he walked through the six-meter-long cylindrical cabin step by step, and finally pressed the button on the outer hatch.

The air in the cabin was quickly evacuated, and the second the hatch opened, Tang Yue said to the oncoming Mars:

"I'm out of the cabin and feeling good."

The old cat has carried all the necessities to the Martian stray dog, and now the Mars rover is really a Thomas train, with the experimental cabin pulled behind the front of the locomotive, food, oxygen and fresh water in the cabin at the moment, and the experimental cabin is dragged by a board car, and the board car is tied with solar panels, this is all the luggage of Tang Yue and the old cat.

The old cat sat in the cab to check the state of the rover, the state of the Martian stray dog was really not normal, the whole front of the car was smashed into a big pie, the frame was twisted, all the glass was shattered, the cockpit is now just a broken hut with ventilation on all sides, and the only thing that can still be used is the steering wheel and accelerator brake. Tang Yue had seen a farm walk-behind tractor in a museum, and he said that it smelled of dieselpunk all over its body, pure machinery, and did not have a single piece of liquid crystal glass.

Now the Martian Stray Dog has also become a veritable walk-behind tractor.

The old cat stuffed the map under the center console, stuffed the letter into the light shield, then turned the steering wheel left and right, stepped on the accelerator and brake, and it was suddenly stunned.

There's something in the co-pilot's storage compartment.

The old cat pulled it out, and it was a wooden picture frame.

It smiled, leaned over to prop up the frame, and carefully placed it on the center console of the Martian Stray Dog.

Tang Yue buried a mobile hard drive in the pit, which was the grave he had dug for himself before, and the hard drive was a copy of the history of human development, and the original was kept in Kunlun Station. He took advantage of the last dawn of the sun to build a tomb for the vanishing human civilization, shoveled the earth in the hazy early morning night, covered and buried the hard drive little by little, and finally stuck the shovel in the dirt.

Mars is not the moon, footprints on the moon can be preserved for hundreds of millions of years, but the wind and sand on Mars will change the landscape, this small tomb does not know how long it can exist, but if nothing else, this shovel is the end of all mankind, Tang Yue took a step back, stared at the long handle of the shovel, and finally saluted.

"Tang Yue, the sun is about to rise." Old cat reminder.

"I know."

Tang Yue circled around Kunlun Station and patted the Chelome probe, who was still sitting on the sand, stretching the solar panels, the indicator light flashing second by second, although it was snatched by this group of people with a temperature control chip, but it didn't seem to care at all, the Cherome watched the sun rise every day, and watched the sun set, like an old man who had gone through vicissitudes.

"We're leaving, I'm sorry we can't take it with us." Tang Yue stopped in front of the Cherome, "Say goodbye to us, say goodbye and flash." ”

Chelome's faint light flickered.

"Goodbye." Tang Yue waved his hand backwards.

He passed by the garage, there were still cans for feces piled up in the garage, the old cat even arranged this neatly, all kinds of tools were stored in the boxes and hung on the wall, Tang Yue closed the door of the garage and pushed the door bolt. Tang Yue finally embraced the descent of the Eagle spaceship, which had saved Mai Dong's life in the first place.

He went out for a walk every day and often chatted with the Eagle spacecraft.

The Eagle was a good listener and never interrupted no matter what was said.

Tang Yue finally stood in front of the main station of Kunlun Station.

For more than 300 days and nights, this is his only home on Mars.

He has become accustomed to the days when he completes his routine every day, comes back and lies on the chair on all fours, and calls the old cat to pour water for him, the old cat sometimes helps him pour water, sometimes shrinks on the chair opposite and does not move, urging it to blow up, Mai Dong is haunted on the screen, I don't know if she is there, sometimes she is not in the core cabin, sometimes she is, but she does not want to appear in the camera's field of vision.

Tang Yue stretched out his hand, and his palm touched the wall of Kunlun Station.

For the first time, he regretted that he had to wear heavy Mingguang armor, and could only touch Kunlun Station through several layers of airtight insulation materials, if he didn't wear gloves, he might be able to feel the smoothness, hardness and warmth of Kunlun Station.

"We're leaving."

Tang Yue's helmet leaned against the outer wall of Kunlun Station and closed his eyes.

"We're leaving."

Behind him, the sun on the horizon finally rose, and the golden sunlight crossed the mountains and desert in an instant, casting the shadow of Tang Yue's upper body on the outer wall of the main station.

"Goodbye."
