A wall apart.

Dai Yue and Zhuo Zhi are inspecting the situation on the first floor of the main building of Cassini Station.

There is almost no light in the corridor, only the head lamp pillars of Dai Yue and Zhuo Zhi two sets of iron floating Tu are swept in the darkness, this scientific research station has been silent for twenty years, and the human footing has made the almost frozen air in the building disturbed again, bringing up fine gray-white snow dust, the dust suspended in the air is a good carrier of the Tyndall effect, and two snow-white pillars of light penetrate the turbid air.

The gravity on Titan was very small, and Dai Yue and Zhizhi pushed their bodies down one after the other, bouncing forward like two frogs.

They changed a lot of positions, and finally they felt that squatting down and jumping was the most appropriate.

Entering from the airlock room, the corridor is flanked by tool rooms, warehouses and laboratories, most of which are closed doors, Dai Yue and Zhuo Zhi inspect one by one, and stuff whatever they find useful into their pockets, like two scavengers picking up rags.

"It's hard to imagine that someone stayed here twenty years ago." Dai Yue sighed, "How far have those people gone?" ”

"At the craziest time, they wanted to send someone to land on Pluto." "It was a huge project, called the 'Edge of the Solar System' project, but it went bankrupt before it could be implemented. ”

"It's bankrupt." Dai Yue shook his head, "If you want me to say, some people are stunned, and they want to run out with all their hearts, but what is there outside?" What's the point of flying in one direction for 10,000 years, and you may not be able to touch a single speck of dust? ”

"It is human instinct to expand the living space." Zhuo Zhi said.

"It's also human instinct to be lazy." Dai Yue smiled and stopped to rest, "No kidding, Boss Zhuo, you can calculate an account, even how far away is Proxima Centauri, the closest to us?" There are four light years, and with our current theoretically fastest concept spacecraft, it takes 4,000 years to fly from the solar system to Proxima Centauri. Thirty generations, that's one hundred and thirty generations. ”

Dai Yue paused, and then said:

"Even with freezing technology, it is an impossible task to span 4,000 years, and if it freezes well, it will stink after 4,000 years."

Zhuo Zhi thought about the situation described by Dai Yue and laughed.

"That's the reason, and the target will be an aquatic spaceship full of stinky frozen fish."

"If we're going to build a spaceship like this, it's going to be incredibly big." Dai Yue said, "In order to prevent human beings from inbreeding and degenerating in spacecraft, at least a sufficient number of gene pools must be carried, right?" In order to maintain the daily life of the crew, it must have strong enough logistics and energy supply, right? It has to have self-sufficient food and fresh water, right? It has to be a completely self-circulating little ecosystem, right? It's not a spaceship anymore, it's a human-made planet - but even if it's built, who wants to go up there? Everyone knows that the first people to board the spacecraft will never be able to see the destination, their children will not see it, their children's children will not see it, these people will only spend the rest of their lives in the never-ending void, what is the difference with a space prison? ”

Insight nodded.

If there really is such a spaceship, if he is allowed to get on, he will definitely not be able to get on.

"The universe is essentially just an infinitely auto-generated game map from a given material." Dai Yue said, "Big and inappropriate, meaningless, what does it make if you are in the solar system or in the Great Magellanic galaxy hundreds of thousands of light years away?" In the Big Magellanic Galaxy, all you see is another Sun, another Earth, another Mars, another Venus, Jupiter, Saturn, Uranus, Neptune – and there won't be another periodic table anyway. ”

What Dai Yue said makes sense.

Everyone has to admit that the solar system is an isolated island in the universe, it is far from another isolated island in the vast ocean, but the inhabitants of the island only have canoes made of reeds, powered by hand-rowed wooden paddles, and the people on the boat are hung up less than 800 meters away.

It's almost an insurmountable barrier.

Why bother to run that far? Not to mention that the hard work has not come to fruition, and all your life is wasted on a journey that is destined to be meaningless.

Wisdom was silent for a few seconds, he thought he was a pioneer, but now it seems that his convictions are not very strong.

Pioneers always thought that the ultimate goal of human civilization was to spread to the outside world, and in the frenzy of a few decades ago, when foreign migration set off a national boom around the world, when Zhizhi was still very young, he also joined others in shouting, "The earth is the cradle of mankind, and human beings cannot live in the cradle all the time!" "Move the Porn Hub servers to Mars!"

Now that the era of chicken blood is over, most people have calmed down, young people like Dai Yue, born in the decline of space exploration, have even less interest in the desolate world outside the solar system, and the magnificent nebulae and wonders in the lens of the telescope are just background maps for the sandbox for them, and they know that humanity will never reach such a distant shore.

"That's true, but you're not bored." Zhuo Zhi said, "You are equivalent to denying the meaning of our external exploration, people must have a hope in the world, right?" To you, the universe is a recurring map, but to some it is a treasure map, full of attractions. ”

"It's sad to live like that." Dai Yue shook his head, "I love something that can't be fruitless in my life." ”

Wisdom knelt on the floor, looking up at the top of the hallway.

He thought to himself: What were the people who endured the extreme harsh nature here for 20 years ago?

If they are still alive, then they are already as old as themselves.

"Give." Dai Yue didn't know where to find a plastic plate and handed it to Zhuozhi.

Zhuozhi took it and looked down, it turned out to be the floor plan of the main building of Cassini Station.

"I just picked it up on the ground." Dai Yue said and stretched out his finger to look around, "The rooms around us are warehouses and utility rooms, the front is the laboratory and the computer room, the right is the elevator and stairs, and the innermost one is the P3 laboratory......"

"Then Dabai should still be in the computer room?"

"It should still be there, but I don't know if it can be fixed." Dai Yue pushed the door of the warehouse hard, and they hadn't searched this warehouse yet.

"Click-" The door was unlocked, but it was frozen.

The door and door frame froze into a single piece, and when you pushed it open, the ice crackled and fell down.

The two of them jumped in, as if jumping into the cold storage, Dai Yue suddenly let out a low exclamation, stopped, and subconsciously raised his hand to cover his eyes.

A blinding light shone in front of him, and he and Zhuozhi saw two figures standing in the dark room.
