"It would be nice to have a campfire." Tang Yue piled the stones together on the ground one by one, like a small mani pile, "When I used to train with Lao Wang in Taklamakan, I often picked up some dead poplar branches and camel thorns to live, and the temperature difference between day and night in the desert was large, and the temperature dropped sharply as soon as the sun set, and we wore wool blankets to bake the fire. ”

"It's a pity we don't have any combustibles on our hands." The old cat picked up a stone and gently placed it on the pile of stones, "There is not enough oxygen, every oxygen molecule in this hellish place is precious." ”

"Do you know the old cat, through the bright light armor, I sometimes feel that I am far away from this world." Tang Yue threw the stone, "I have never really touched this land, everything I see, is also through the glass mask, who knows if this is true or false?" ”

"Even if you don't wear the armor of light, everything you see and touch is just nerve signals, they are essentially intercellular electrical currents, what you see, touch, and feel must be real? The human brain is trapped in a closed shell, relying on nerve endings that dot the body's surface to perceive the outside world. The old cat shrugged, "Strictly speaking, you are not actively learning about the world, but passively obtaining information. ”

"The problem with the brain in the vat?" Tang Yue thought for a moment, "It's too philosophical." ”

"It's not really a philosophical question." "It's a very rigorous matter of biology, physics, and psychology, and until Darwin, Pasteur, and Jung have figured out the human brain, Mr. Kant should sit by and have afternoon tea." ”

"It is always said that the end of science is philosophy, and the end of philosophy is theology."

"Whoever says something like that, I suggest you can go back and reinvent it." The old cat continued to build stones on the stone pile, "mixing rigorous empirical cognition, reproducible experimental verification, and universal methodology with the nonsense of the gods, and the twelve years of compulsory education were all in vain." ”

"Darwin and Herr Huxley were undoubtedly the leading men in the difficult journey of mankind to know themselves, Freud and Mr. Jung were also powerful supporters, and Kant and Mr. Rousseau set up the ladder of siege—and as for Mr. Aquinas, his mother should call him home for dinner."

"Well, I know you're a cat who despises theology."

"No, I have never despised theology." The old cat shook his head, "Really." ”

Tang Yue was skeptical.

"I have never denied the importance of theology in human culture." The old cat continued to raise the pile of stones, "On the high tower of human history, every brick is indispensable, if you want to forcibly extract a ......"

The old cat gently pinched a stone and jerked it.

Boom.

"It's going to collapse."

Tang Yue looked at the stones scattered all over the place, and suddenly smiled.

"Why are we talking about this?"

"You started first." The old cat spread out his paws.

"Sometimes I feel like a philosopher, the only and last philosopher in the world." Tang Yue leaned back and looked up at the sky, "Later, I thought, the universe is so big and so vast, and a person's mind is too small...... Is the mind really something as great as the starry sky? ”

"When man thinks, God laughs."

"I can already imagine some old man with a white beard rolling on the floor with a smile on his crutches."

"I imagined some old white-bearded cat rolling on the floor laughing."

Tang Yue and the old cat chatted with each other, Tang Yue said that they lacked a bonfire, which was not wrong, if a bonfire could be lit, then this lonely and cold desert night would probably become warmer.

"You wait." The old cat got up and returned to the experimental module of the Martian stray dogs, and returned a few minutes later with a small lamp.

The old cat half-buried the light bulb in the sand, and then turned on the switch, and Tang Yue and the old cat's faces were illuminated by the dim light.

"The solar-powered emergency light can last for two hours when fully charged, but the brightness is not too high." The old cat said, "Do you feel a little warmer?" ”

"The temperature in the Mingguang armor is twenty-five degrees Celsius." Tang Yue sat cross-legged on the ground and looked at the small light source in front of him, "I'm not cold." ”

"Then I'll put it away."

"Wait." Tang Yue stretched out his hand to stop it, looking up at the other party's dirty cat face, "It's better to keep it, I feel a little warmer." ”

A man and a cat sat together in the dim light, the orange-yellow light wrapped in a small space by the bodies of the two people, and the solar-powered emergency light was unstable and occasionally flickered, making it look more like candlelight.

"I feel like we're two emperor penguins." Tang Yue said.

"Emperor penguins?" The old cat asked.

"Emperor penguins gather together during a blizzard to fight the weather." Tang Yue explained, "The vast majority of creatures in this world have the ability to resist external aggression only when they are together. ”

"But this is the desert." The old cat said, "How can there be emperor penguins in the desert...... Think of the scene where penguins are walking in groups on the sand, staggering, climbing to the top of the dunes, and then surfing on the dunes with their belly sticks to the ground. ”

"Nope." Tang Yue waved his index finger, "We are the emperor penguins in the desert." ”

The old cat was stunned for a moment, and immediately understood what Tang Yue meant, they were emperor penguins trekking in the desert, the kind of black and white big fat birds could not fly, they were inconvenient to move on land, they were clumsy and slow to move, they could only adapt to the cold and low temperature climate of the polar regions, and there was only a dead end in the arid and hot desert - but Tang Yue, the penguin, was wearing a spacesuit and carrying enough water and ice on its back, and it had to use ice to cool itself down while moving forward.

On a planet full of deserts, where can emperor penguins go?

Tang Yue imagined the lonely and helpless emperor penguin looking around in the desert, staggering forward, leaving a line of shallow footprints, before it died of thirst, could it find a refrigerator in the middle of the vast desert?

Emperor penguins looking for a refrigerator in the middle of the desert.

Tang Yue thought silently.

Is the former incredible, or is the latter more whimsical?

"Is it taking longer to charge the Martian stray dog today than before?"

"Yes." The old cat replied, "Since yesterday, the charging time of the Martian stray dog has begun to be significantly longer, and this is because the intensity of the sunlight is weakening. ”

"The sun is waning, the reason for the season?"

"It's the season." "We are gradually entering the summer, the atmospheric activity is starting to intensify, the air is becoming turbid, and the light flux is decreasing. ”

Tang Yue sighed.

"Will the stray dog make it to the finish line?"

"No problem." The old cat replied, "We only have sixty kilometers left, and we will reach our destination in two days, even if Mars is about to be destroyed, there is no hurry for these two days." ”
