"Of course it's dizzy, it's hard to adapt at first,"

didn't expect the man to get up and take two steps, Shangguan Rin quickly pulled him back and pressed him on the chair,

"Come, don't move, I'll take it off, and I'll deal with it for you later when I have time; After all, this pair is my backup, and the focal length and bioelectric parameters are mismatched, so it's no wonder if it's not dizzy~"

After a while, I was in a hurry, and I cleaned up the "pupil display", and before I knew it, the atmosphere in the room was a lot more harmonious.

Seeing the black technology displayed by Shangguan Rin, Fang Ran sighed for a while, he stared at Rin's Zhan Ran's eyes for a while, and then suddenly realized, and guessed how she read and wrote the lengthy results of large prime number decomposition:

"So, Rin, you've been wearing a pupil?"

"yes, I only take it off before going to bed, it's the same as your habit of using your mobile phone,"

While explaining, the empathetic girl guessed Fang Ran's question, and smiled very rarely:

"Well, you guessed right, my eyes were originally blue."

……

After knowing Shangguan Rin's identity, it is conceivable that Fang Ran's mental state has undergone drastic changes.

Not only that, but so did the trajectory of his life.

Time passed day by day, the end of the semester is getting closer and closer, and there are only a few short days before the final exam. And now, not to mention the fatalistic theory that he deeply believes, just the arrival of Rin, which brought him—or any earthling, would have a shock, in comparison, exams, studies, diplomas, have become secondary matters.

So what's most important right now?

From Fang Ran's point of view, what he was most curious about was, of course, the world Rin came from.

The "world" is naturally a "unique" attribute in human language, and before the birth of the concept of science fiction, probably only religion would generalize it:

Whispers such as "past life, next life", and the fantasy of "countless worlds", Fang Ran will only scoff at them.

However, since the long-held view is that "civilization will eventually die", what about the civilization where Shangguan Rin is located, how can it develop all the way to interstellar voyages and travel through distant time and space to reach the earth?

The theory was completely contrary to reality, which piqued his curiosity even more.

At night, the sky is full of stars, driving away from the glittering glamour of the big city, and the electric bus lies quietly on the fork of a highway out of the city.

Sitting in a bus with a wide view, the lights are completely turned off, and from the outside, if you don't notice someone inside, it's like a random vehicle parked on the side of the road; The commuter bus of the Hilton Hotel is quite high, and there is a glass sunroof between the roof beams, which is convenient for passengers to watch the scenery, and now, lying on the two seats that are completely folded, Fang Ran and Shangguan Rin are very close, and the two of them started talking in this completely relaxed and somewhat ambiguous posture.

"Do you see the night sky, Fang Ran; There is less light pollution here, and many stars can be seen. ”

"yes.

But, to be honest, I didn't pay much attention to this before, on the one hand, I didn't have a special interest in astronomy, and on the other hand, as you said, the intensity of light at night in modern cities makes it difficult for people to see the stars;

Even the Milky Way is very dim, and people with poor eyesight can't see it at all. ”

"Well, you're right.

But I think the main thing is that I don't have time or mood~"

Shangguan Rin's voice was as gentle as ever, but it hit the nail on the head, and what he said was related to Fang Ran:

"Well, not only me, but also the vast majority of people in the world.

Looking up at the starry sky, no matter what you can see, what is the meaning of your life and what real help does it have?

Many people have subconsciously thought about it, and the conclusion is, of course, 'no', every day is busy, except for professional workers, how can ordinary people have the leisure to pay attention to these? Although the E.R.A. space program has been in full swing in recent years, regardless of the motivation for doing so, when the wave of enthusiasm has passed and there are no breakthrough discoveries, people will be disappointed and move on to the next low ebb.

Speaking of which, Rin, what do you think of our world's space activities? ”

Fang Ran's question was improvised, he first finished his point of view before he remembered to ask Rin, the latter, he didn't think it was strange, and the answer was very fast:

"I have limited understanding, but you're right, chemical rockets have no future.

As for 'electromagnetic catapult', this world will have sooner or later in the future, but at most it is still very difficult to touch the edge of the stargate to reduce the cost of some space launches and increase the scale of deployment;

I will not speculate on the rest of the matter. ”

"'Stargate'?"

"Well,—— you can understand it as a 'wormhole', and we approach the earth through it."

Shangguan Rin's tone had been quite calm, but Fang Ran was surprised.

Although he had thought before, with the current natural science theories of human beings, Shangguan Rin's world could hardly exist in or near the solar system, and if it was to talk about the more distant deep space, then her civilization must have mastered a "non-traditional" time travel technology.

But is it a "wormhole", they actually have such a technology to create a wormhole?

This question may have taken a long time to unfold, so Fang Ran temporarily suppressed his desire to explore, and he turned the topic to the purpose of today's drive:

"It's completely incredible, but, Rin, where is your world?"

"It's far away, that's why I'm here.

It's just that there is no large detection equipment, such as astronomical telescopes, and I am afraid that there is no way to see it, well, there it is. ”

As she spoke, the girl raised her hand and pointed in the direction of Nantianqiu:

"According to the name of the earth, you see, it is the constellation of Lyra, just look in that direction, dR13F262; As for the distance, well...... Now it's about 70,000 light-years.

Naming rules, you can slowly become familiar with the planet we live in, called 'Planet 33', 'Lyra'. ”

Looking in the direction Rin had pointed out, Fang Ran didn't speak, he stared intently.

Lyra, 70,000 light years, what is this concept?

I just know that it is still within the Milky Way......

I can't imagine that, though, Rin uses the earth's unit of measurement, Fang Ran still feels powerless.

Light has to travel for 70,000 years to reach the distance, this kind of span, is completely beyond the intuitive understanding and grasp of a person.

Lying on his seat, looking up at the deep night sky, he didn't know how long ago he had last done this, Fang Ran looked at the faintly flickering stars, he knew that he couldn't be sure which of the stars near the constellation Lyra was the one Rin was talking about.

But, with the previous evidence, although it was all so implausible, he also chose to believe her completely.

"It's too far away, really, too far away.

Rin, your civilization must be extremely technologically advanced, right?

Otherwise, you wouldn't have been able to make a 'stargate' and reach Earth, and besides, you wouldn't have been able to travel like this, would you have come by a spaceship?

At a distance of 70,000 light-years, how did you discover the Earth and know that there was a civilization on it?

The two civilizations are so far apart, but you are very similar to us on the outside, and perhaps on the inside, will the evolutionary route be exactly the same, or is there some connection between us? ”
