Tang Yue pulled his left foot out of the sand and took a tentative step forward to confirm that there was solid ground under the sand. Tang Yue tried to step firmly on it, but the quicksand immediately submerged his calf. Tang Yue could see everything.

No, there may be flat ground or a pit under the sand, so be careful every step you take.

Are you going in the right direction? Tang Yue stopped to rest, panting.

As long as he kept a straight line, he would be fine. The old cat was moving around on his back.

Why are you twisting all the time? Tang Yue turned his head, you are very heavy, do you know? As a cat, you have the weight of a pig.

I am generating heat through friction. Didn't you ask me to do this? The old cat is rubbing its hands and feet violently. I don't know if you are walking in a straight line. I told you that it is difficult for humans to keep the direction constant in the dark.

You may drift to the left unconsciously. I can't see anything and I can't determine the direction for you.

Move to the left. I will pay attention. I will pay attention. Tang Yue lifted the old cat up behind him. It was very inconvenient to carry the Mingguang Armor on his back because there was a life support system in between.

Because Tang Yue's hands are not long enough, my stride length is also 0.4 meters now. Since I carried you on my back, I have walked 2123 steps and 2124 steps. We have walked a total of

One thousand four hundred and fifty meters.

Can you still hold on?

Not bad. Tang Yue nodded. He lowered his head and walked forward step by step. Without the old cat to guide him, Tang Yue had no choice but to go up on his own. When I was on earth, I could easily run for five seconds.

I traveled the entire kilometer without panting and now only have two kilometers left, which is not a problem, not a problem.

Before he could finish his sentence, Tang Yue's body suddenly tilted. He stepped on something unknown with his right foot and lost his balance. He staggered and almost fell.

Tang Yue?

It's okay, it's okay. Tang Yue took a step across to adjust his center of gravity, subconsciously grabbed the old cat with both hands, took a deep breath, and we continued walking forward.

He tried his best to ensure that the direction remained unchanged, but Tang Yue himself knew that this could not be guaranteed. He stumbled along the way and fell countless times. If the old cat hadn't remembered it, Tang Yue would have been dizzy long ago.

.

Two thousand one hundred and twenty-eight steps.

Two thousand one hundred and twenty-nine steps.

Two thousand one hundred and thirty steps.

Tang Yue glanced at the time. The current time was 11:33 in the morning. It took them two and a half hours to walk the distance of more than a thousand meters. In order to save power, Tang Yue reduced the heat preservation power of the Mingguang Armor to the minimum.

His limbs were numb from the cold, and his toes were almost frozen off.

The thermometer shows that the outside temperature has dropped to minus 79 degrees Celsius, and is still falling rapidly. It is about to fall below minus 80 degrees Celsius. The dust storm has completely cut off all sunlight. In this case, the surface temperature will drop to a considerable

Terrible situation.

Are you cold? Tang Yue asked, your broken spacesuit cannot be heated. If I had known earlier, I should have kept an extravehicular work suit at Kunlun Station, just like the Z9 on the space station.

I am more resistant to freezing than the average person, and I can still withstand this temperature. The old cat huddled behind Tang Yue with its eyes closed. The wind and sand were blowing in front of it, so Tang Yue's body helped it block most of the strong wind. Z series

The extravehicular suit is bulkier than the Mingguang Armor, and you can't walk in that thing.

Tang Yue nodded.

If the temperature is too low, the battery may be overwhelmed.

I have an isotope battery with very low power. Its main function is to ensure the normal operation of the main battery. The old cat said that this means that I have a heart that generates heat.

12:40 noon.

Three thousand five hundred and seven steps.

Tang Yue took this step and gasped for air.

He put the old cat down and sat down on the ground, exhausted.

I have never been this tired after running two five kilometers. Tang Yue moved his hands and five fingers, but his five fingers no longer obeyed. The Mingguang Armor's battery still had half of its power. It was already halfway through two kilometers.

There is still more than one kilometer left to go. Old cat, can you confirm the direction?

The old cat sat next to him and curled up in a ball. It seemed that the temperature was too low and it had to find a way to maintain its internal temperature.

The number on the thermometer stayed at minus 89 degrees Celsius. This temperature has exceeded the lowest temperature in the history of the earth. Without the Mingguang Armor, Tang Yue could not survive for more than a minute when exposed to the outside air.

Go straight. The old cat said, keep going.

I had no feeling in my toes. Tang Yue leaned over and pinched his foot. It felt like a stone. I thought he could break off the toe.

Is Mingguang Armor still working normally? Lao Mao asked.

The Mingguang Armor is in normal condition.

Where are the batteries and oxygen? The old cat asked again.

There was still enough. Tang Yue coughed a few times, bit the drinking tube, and drank the last bit of fresh water in the water bag. Then he got up from the ground, "Get up, it's time to go, we will continue to move forward."

Aren't you going to take a rest?

There is not much time, there is still more than one kilometer to go, and every second you delay is a second lost. Tang Yue mustered up all his strength to carry the old cat on his back, and the more I rested, the more tired I became. If I sat down like this, I would really be unable to walk later.

Moved.

2pm sharp.

Tang Yue walked staggeringly on the sand. Every step forward he seemed to fall, but he immediately stood firm. The sand had already buried his knees. Tang Yue had long lost track of how many steps he had taken.

, it may be 4,500 steps, or it may be 4,600 steps. He no longer calculates the distance forward. As long as the direction is correct, he will see his destination sooner or later.

Tang Yue, can you still hold on?

Yes. Tang Yue nodded, how far have we gone?

Two thousand seven hundred meters. The old cat replied, there is less than one thousand meters left.

There was still less than a thousand meters left. Tang Yue's throat was hoarse, his throat was so dry that it was smoking, and it took a lot of effort to speak every word.

Tang Yue could no longer feel the existence of his limbs. The Mingguang Armor was as cold as an ice cave. Even so, it was still nearly 90 degrees Celsius higher than the outside temperature. The outside temperature continued to drop in the past two hours. Now

It has dropped to minus ninety degrees Celsius.

Tang Yue's brain was unable to communicate with his hands and feet. The extreme low temperature and fatigue froze everything to death, including Tang Yue's brain. He seemed to be a robot with no thinking and no memory. There was only one program going back and forth in his mind - walking.

, go forward, keep going forward.

The brain cannot convey any instructions to the body and limbs, but the legs are still stepping forward mechanically. I don't know where the strength comes from, like a conditioned reflex.

Tang Yue, your condition is not very good. Do you want to stop and rest?

No, no need, time is running out.

Tang Yue coughed violently. He began to have chest tightness and shortness of breath, difficulty breathing, and burning pain in his lungs. His throat was blocked by thick saliva. He wanted to cough but couldn't, and even if he wanted to swallow, he couldn't. Mingguang Kai's life monitoring system kept

When the alarm was called, Tang Yue's heart rate remained high and his heart was beating violently. It had exceeded a hundred times a minute and was still rising.

The old cat raised the small emergency light in his hand, and the light illuminated the dust and sand in the airflow.

Tang Yue.

Um?

Look, it's snowing.

Snow? Tang Yue raised his head and saw flying white ice crystals in the light. I don’t know when, the wind and sand were mixed with snowflakes. They fell on the mask glass and shoulders of the Mingguang Armor. They stayed there for a long time, and soon they disappeared.

Accumulate a thin layer.

These are dry ice snowflakes. The atmospheric temperature has been lower than the freezing point of carbon dioxide. The old cat also raised his head and whispered, so they have solidified and crystallized.

This is the first snow on the Ixi Plain of Mars in the year 2053 of the Earth's calendar, at the turn of spring and summer, during a long dark night.

It's snowing. It's snowing. Okay, we can make snowmen and have snowball fights.

Tang Yue muttered nonsense unconsciously. He crossed the top of the sand dune and was about to go downhill when his feet suddenly went soft. This time he didn't have time to stabilize his balance because his brain and limbs were extremely slow. Tang Yue fell to the ground in a daze.

His cheek hit the mask of the Mingguang Armor, making stars pop out of his eyes. At the same time, he threw the old cat behind him, and one person and one cat rolled down the sand dune, all the way to the bottom of the slope.

Tang Yue! Tang Yue! Tang Yue, where are you? Can you hear me?

The old cat was also stunned. It shook off the sand on its body, held up an emergency light, got up and shouted, it and Tang Yue were separated. There might only be a few meters between the cat and the human, but they couldn't see each other.

other side.

Neng Neng Tang Yue's voice was very weak.

Can you see the light in my hand? The old cat asked.

Neng. Tang Yue turned on the light inside the Mingguang Armor mask, and a white light lit up in the darkness a few meters away from the old cat.

Tang Yue, how are you doing? The old cat fumbled and found Tang Yue, who was lying motionless on the sand. How are you doing?

My situation may not be good. Tang Yue whispered, "Old cat, I feel so uncomfortable."

The old cat helped him up, what's wrong with you?

Tang Yue was panting violently, his face was pale, as if he had some sudden illness, his mouth was wide open, his eyes were wide open, his expression was distorted, I can't breathe, I, I

The old cat was surprised.

Tang Yue raised his hand to scratch his own throat, but the mask of the Mingguang Armor blocked him. Tang Yue could only reach out and grab the old cat's shoulder tightly, and used his other hand to tear hard on the Mingguang Armor, as if he wanted to tear it apart.

Enlightened and armored, the young man's eyes showed fear and helplessness, and the muscles all over his body began to twitch in pain.

Old old cat, help me, I can't breathe, help me

Tears overflowed from Tang Yue's eyes. He used all his strength to hold on to the old cat, his fingers digging into the fibers of the cabin suit.

Tang Yue! Tang Yue?

me

Tang Yue could no longer make any sound. The strength in his hands gradually faded away, the expression on his face suddenly solidified, and his pupils began to dilate.

Mingguang Kai's life monitoring system beeped - there was a sound.
Chapter completed!
