When Tang Yue woke up again, he realized that he had just passed out, and he didn't know how long he had been unconscious. Tang Yue tried to move, and found that he was being hugged—someone was holding his helmet.

At this time, Tang Yue realized that his posture had also changed, he was lying on the sand before, but now he was lying on his back facing the sky.

"Awake?"

Tang Yue was stunned for a moment, and quickly raised his head, through the mask of the Mingguang armor, he saw a huge spherical head on the top of his head, and the big round head was looking down at himself - of course it was not an alien, but the helmet of the old cat's spacesuit.

The old cat made Tang Yue half-lie on his lap, hugged Mingguang Armor's helmet, and looked down at him.

"Old cat?" Tang Yue saw the cat face in the glass mask of the other party's spacesuit, and was surprised, "You haven't hung it yet?" ”

"Hang your uncle, if I am two hours late, it won't be me, but you." The old cat leaned over and pointed to the wrist of the light armor.

Tang Yue lay on the old cat's lap, raised his left hand, and brushed the dust off the monitor screen on his wrist.

The power of the life support system has dropped by more than half, and the bright light armor is giving an alarm, and a small orange and yellow exclamation mark sign is flashing.

The air pressure in the oxygen cylinder has also been greatly reduced, and there is less than 0.5 atmospheres of oxygen left in the main oxygen cylinder, which is already approaching the red line of the alarm, and the main oxygen cylinder in the Mingguang armor life support system can store about 5 megapascals of oxygen, which is enough for Tang Yue to be active outside the cabin for eight hours.

Tang Yue had been busy all day today, and the oxygen in the Mingguang armor was almost exhausted.

According to the design, once the air pressure in the main oxygen cylinder of Mingguang armor drops to 0.4 atmospheres, then the life support system can no longer deliver oxygen normally, at this time, Mingguang armor will automatically connect to the backup oxygen cylinder, the backup gas cylinder is for emergency use, only 1.2 kg of oxygen is stored, and the use time does not exceed forty minutes.

The old cat was right, if it came an hour late, the oxygen and power in the Mingguang armor would all be exhausted, and Tang Yue would either freeze to death or suffocate to death.

Tang Yue poked the monitor screen with his finger and sighed.

"EVA is EVA, and sure enough, no power is a normal plot."

"No power is a normal plot?" The old cat didn't understand what this meant.

"That's what I'm talking about." Tang Yue pointed to his chest, "The EVA system, in addition to being an abbreviation for the Extravehicular Activity system, is also the name of some kind of giant super humanoid weapon, which will run wild once the power runs out. ”

The official name of the Mingguang armor extravehicular spacesuit is the EVA system, and the full name is the Extravehicular Activity System, that is, the extravehicular activity system, but just looking at the abbreviation it looks like a very high secret weapon.

The old cat helped him up, and Tang Yue sat up, "How long have I been in a coma?" ”

"It's eleven 20 p.m., you've probably been unconscious for an hour or so, and you're lying on the ground when I find you." The old cat replied, "The wind speed is starting to decrease. ”

Although the wind speed was reduced, Tang Yue couldn't see any difference, it was still dark all around, and the only thing he could see clearly was the old cat's face, which was because the light in his helmet illuminated the old cat's face.

"The wind speed is now 38 meters per second." The old cat said, "But why did you run out?" I told you to stay in Kunlun Station and not to move. ”

"I waited for more than an hour." Tang Yue replied, "You haven't come back...... Then when I took back the safety rope, I found that the rope was loose, so I came out to look for you, but why weren't you on the rope? Did you untie the safety rope? ”

The old cat nodded.

"The rope was wrapped around the gangway and couldn't move, so I unbuckled."

"But you walked for more than an hour and didn't come back." Tang Yue asked, "Why does it take so long?" Half an hour back and forth? ”

"I walked more than once because I was almost lost." The old cat replied, "I missed Kunlun Station, walked more than ten meters forward, only to realize that the situation was wrong, and when I turned around and came back to find Kunlun Station, I found that you were not there, so I followed the rope to find you again...... It's a good thing you have a safety rope tied to you, otherwise I might not find you. ”

Tang Yue breathed a sigh of relief.

The old cat is fine.

Everything was a false alarm, and in the process of delivering supplies for the last time, the most dangerous thing was not the old cat, but Tang Yue...... Tang Yue was unconscious in the sandstorm, the life support system of the Ming Guang Armor was almost exhausted, if the old cat did not find him, then Tang Yue would freeze to death in a coma.

He unknowingly brushed shoulders with death, turned around in the ghost gate, and was dragged back by the old cat.

Mingguang armor began to call the police, Tang Yue glanced at the terminal display screen, the air pressure of the main oxygen cylinder had dropped below the red line, and the spare gas cylinder was connected to Mingguang armor.

The air pressure inside the Mingguang armor suit is generally maintained at about 40 kPa, that is, 0.4 atmospheres, this pressure is mainly provided by the oxygen cylinder, once the spare gas cylinder is activated, the forty-minute countdown begins.

"Let's go, let's go, we should go back, you have forty minutes of oxygen left."

The old cat pulled Tang Yue and climbed back with difficulty along the safety rope.

The old cat crawled in front, Tang Yue followed behind it, and the two of them were strung on a rope, one in front and one behind them as if they were climbing Mount Everest.

After being in a coma for more than an hour, Tang Yue finally regained some of his strength, "Have you already delivered the last box?" ”

"Delivered." The old cat replied, "All the supplies are firmly tied to the cargo hold of the Eagle spacecraft, and they are all in place, ready for launch." ”

"Don't you need to check it any more?"

"We've done what we can do."

Tang Yue was a little relieved, they finally got this step done, this 400-kilometer express delivery was finally packed, this is probably the most difficult express delivery ever...... If it weren't for this damn sandstorm, the situation wouldn't have become so troublesome at all.

"When will it be launched?"

"There are six suitable launch windows tomorrow during the day, and my original launch time was half past eight in the morning...... But now the plan can be completely nullified. The old cat shook his head, "In the current situation, there is no point in planning ahead, we have to observe the wind speed, when the wind speed is lowered and when it is launched." ”

"Fifty meters per second?"

"Fifty meters per second is the design limit." "Of course, the lower the wind speed, the better, preferably as low as 30 meters per second...... Below 30 meters, there is a greater certainty, and if the wind speed can be reduced to this point, we may be able to resume communication with the United Space Station. ”

Tang Yue nodded.

"Hurry up and recover, I'm afraid that little girl in the sky is already crying now."
