To my frozen hometown

Chapter 87 One of the main meanings of an adult's existence may be to protect children's dreams

The three of them walked around the ecological garden on the first floor. In the old man's introduction, Liu Yuan saw many things that she had almost forgotten, such as blooming flowers and abundant fruits.In this snow-white world, their colors are undoubtedly rare, and some people who rarely see them may never see them once in their lives.

Just like Al, at this time she was attracted by a bunch of flowers, squatting beside a flowerbed, quietly watching the swaying of the petals.

In the old man's description, the girl learned that these plants are alive, which made her a little surprised, but she also wanted to understand the truth of these lives even more.

Facts have proved that for unknown things, human beings are curious besides panic.

One of them hinders the pace of human beings, and the other pushes forward human beings. Perhaps this is the initial contradiction in the hearts of human beings. It is through the development and survival of such contradictions that complex and contradictory creatures like human beings are created.

Probably because he noticed the concentration in the girl's eyes, a smile appeared on the old man's face. He likes children because children are always innocent.Because it is always easier for children to fantasize about the future than adults who have bowed to reality.

Fantasy, on the other hand, keeps people going.

They were the hope of the future, the old man had always thought so.

"Do you like these flowers?" Standing at the exit of the ecological park, the old man asked Al.

Al might have been taken aback by the old man's sudden question, and turned around in a panic.

She looked at the old man, then lowered her head, hesitated, and said nervously.

"Well, they're beautiful."

"Then when you leave, I can give you one." The old man smiled gently and glanced at his ecological garden.

"Believe them, and they will also want to go to the outside world to see."

"By the way, little girl, do you know what kind of miracle these tiny lives once created?"

"Well, I don't know..."

"They used to be all over the planet, they used to bloom anywhere."

The old man's voice was flat, but it couldn't cover up the magnificence he described.

Al's eyes were slightly in a trance, probably because he imagined the past that the old man said, and imagined the appearance of flowers all over the ground.

As for Liu Yuan, she glanced out of the window with a little regret.

That boundless ice and snow has buried all her memories of the past.

"Okay, let me take you to the third floor, where I usually work, which is the research area of ​​this observatory."

As the old man said, he led the two of them towards the top floor.

Liu Yuan and Ai Er followed behind him, each thinking about their own affairs, on the one hand, the regrets that had been compromised, and on the other hand, the yearning that had not yet dissipated.

"Liuyuan." On the stairs, Al suddenly raised his head and asked Liuyuan.

"Will the snow on the ice sheet melt in the future?"

Hearing this question, the old man looked at Liu Yuan. He knew that Liu Yuan's next answer might be very important to the girl.

Because even he could see that the girl trusted this wanderer who didn't look so friendly.

Facing the girl's question, Liu Yuan thought for a while, and finally answered slowly.

"meeting."

She finally chose this relatively beautiful answer, even though she had seen too much misery.

"En." Al responded softly, looking forward to turning around and looking at the flowers, fruits, plants and trees in the ecological garden.

"That's great."

"Heh." The old man stretched his old brows and showed a shallow smile.

He nodded to Liu Yuan, and Liu Yuan silently looked away in response.

Really two energetic young people.

The old man thought so.

I believe their journey will be very interesting.

But in fact, the old man didn't know that Liu Yuan was a cold-blooded lunatic, and she would take the girl to die.

And the girl will never see the day when the ice and snow melt.

······

The third floor of the observatory is pale because its dominant color is white.White walls, white floors and white tables and chairs constitute the general structure of this floor.

Everything seems to be gray and white, only the computer on the right side of the room is displaying a picture with distinct colors.

Its background is pitch black, but there is a huge glowing sphere in the center of the image, and a small circular shadow is mixed in the middle of the sphere.

"This is what I call the Lingxing method."

He should have noticed that Liuyuan and Al were observing this photo, the old man stood beside them and explained.

"In addition to revealing the existence of a planet, this method can also tell us the size and orbit of the planet. After that, we can determine the discovered planet by observing the changes in light." Is it in the habitable zone, or in other words, measuring the distance between the planet and the star it orbits to determine whether liquid water exists on its surface."

"At the same time, we can also use the received stellar spectral type to infer the temperature of the star, so as to find a galaxy suitable for human beings to stay temporarily."

"How about this star?" Liu Yuan looked at the data on the screen and asked inexplicably.

"Class A spectral type, mass 3.1M⊙, radius 2.1R⊙, brightness 40L⊙, strong hydrogen lines, proportion of main sequence stars 0.60%, temperature range 7-500K." The old man said, shaking himself Head: "No, it's too hot."

Liu Yuan shrugged his shoulders, as if he wanted to show that he could roughly understand, so that she would not appear so ignorant right now.

But it is undeniable that apart from the temperature, she basically couldn't understand other data.

The old man walked to the computer and started to adjust the parameters again, while continuing to talk.

"However, it is not the galaxy that I am mainly tracking now. In the last three months, I happened to be able to observe a habitable galaxy that I discovered before. Unfortunately, the snowstorm these days is really too big, and I only We can wait until the snow is a little smaller to conduct research."

"Oh, that's right." Saying this, the old man seemed to think of something again, perhaps because he was getting old, and he couldn't finish the sentence at once recently.

"Liu Yuan, and this little girl, have you seen the meteor shower?"

"If not, I guess I should say you're in luck, because there's going to be one here in a few days, and it might be quite grand."
